    Understanding the complexity of designing dynamic textile patterns2011Ingår i: Proceedings of the Ambience conference, Borås, Sweden, 2011, s. 28-30Konferensbidrag (Refereegranskat)
    Abstract [en]

    Through a smart textile design project we have identified two sets of complex issues generally relevant for design with state changing materials. Specifically, we show how the temporal dimension of smart textiles increase the complexity of traditional textile design variables such as form and colour. We also show how the composite nature of smart textiles creates a series of interdependencies that make the design of the textile expressions additionally complex. We discuss how these forms of complexity provide opportunities as well as challenges for the textile expressions, and we show how we dealt with them in practice.

    A state-of-the-art Literature Review of Upcycling: A Clothing Industry Perspective2016Ingår i: CORTEP 2016 - Book of Abstracts: 16th Romanian Textiles and Leather Conference / [ed] Avadanei Manuela, Bucharest: Editura Acreditata de Cncsis Bucuresti , 2016, s. 121-Konferensbidrag (Refereegranskat)
    Abstract [en]

    Aim: The purpose of this study is to review and appreciate the developments in the literature of upcycling domain; (i) To comprehend the concept of upcycling and subsequently, understanding the difference among the prominent terminologies used in the literature (ii) To identify application of upcycling across various industries; (iii) To propose a framework of upcycling practices for clothing industries based on the insights.

     Methodology: A scientific literature review procedure proposed by Mayring (2002) was adopted to select and screen the paper which comprised of four steps; (i) Material collection: The collection of material is well defined and delimited based on the profiling approach. Each paper is defined as unit of analysis; (ii) Descriptive analysis: Different criteria are set to analyze collected materials. These are publication year, journal, methodology and author affiliations; (iii) Category selection: To do analysis different categories have been identified. Further those categories were divided into sub-categories; (iv) Material evaluation: According to above mentioned categorization, research papers are analyzed and interpreted to form a conceptual framework.

     Result: The paper has identified terminologies and definitions used in the literature. Recycling may be considered as  the use of the material properties (e.g. as a fire retardant non-woven material in a mattress spring cover) (Morley, Bartlett et al. 2009). Down-cycling may be conceptualized as making an inferior product or broken down into raw material. However, several scholars proposed various definitions of upcycling. The prominent may include: (i) Value/quality of product is improved by making superior product. (Dervojeda, Verzijl et al. 2014); (ii) Giving new value to materials that are either discarded, or are not being used anymore" (Fletcher and Grose 2012); (iii) repurposing lower-value items such as a neck scarf to construct a higher-value end use item, such as a wrap skirt or halter top (Janigo and Wu 2015). The results indicated that designing may be considered as one of the important steps in upcycling process. The process of redesigning consists of ideation, reconstruction and fitting. The limitation of redesigning is variability in size and pattern. This can be overcome by; craftsmanship, time, innovation, provenance, desire, narrative.

     Conclusion: The extant literature revealed that no study so far has attempted to summarize the literature in upcylcing area. Thus, this could be seen as a significant and unique contribution to the literature. Further, the bibliography and insights provided in the study may be used by future scholars as a ready reference for their research.

    Textile qualities of regenerated cellulose fibers from cotton waste pulp2017Ingår i: Textile research journal, ISSN 0040-5175, E-ISSN 1746-7748Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Cotton is not the answer to meet the rapidly growing demand for textile fibers. Wood-based regenerated cellulosefibers are an attractive alternative. Since wood is a candidate to replace fossil raw materials in so many applications of thecircular economy, other sources need investigation. Cotton linters work in the viscose process – can cotton waste beused to make dissolving pulp? We describe the textile qualities of lyocell fibers from (i) pure cotton waste pulp and(ii) blending with conventional dissolving pulp. The staple fibers were tensile tested, yarns spun and tensile tested andknitted, and tested for shrinkage, water and dye sorption, abrasion resistance, fuzzing and pilling, staining and fastness.TENCEL staple fibers and off-the-shelf TENCEL yarn were used as references. The results show that the two studyfibers had tenacity and an E-modulus that exceeded the staple fiber reference. Also, the study yarns were at least as goodas the spun reference yarn and the commercial off-the-shelf yarn in terms of wet tenacity. Single jerseys made from thestudy yarns shrunk less upon laundering, which is surprising since they could absorb at least as much water at acomparable rate as the references. Dyeability, staining and color fastness, durability and pilling tendency showed thatthe two study fiber tricots performed at least as good as the references. This study suggests that cotton waste is apromising candidate for special grade pulp to suit niche regenerated fiber products or to spice up conventional woodbaseddissolving pulp.

    Ioncell-F: ionic liquid-based cellulosic textile fibers as an alternative to viscose and Lyocell2016Ingår i: Textile research journal, ISSN 0040-5175, E-ISSN 1746-7748, Vol. 86, nr 5, s. 543-552Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Ioncell-F, a recently developed process for the production of man-made cellulosic fibers from ionic liquid solutions by dry-jet wet spinning, is presented as an alternative to the viscose and N-methylmorpholine N-oxide (NMMO)-based Lyocell processes. The ionic liquid 1,5-diazabicyclo[4.3.0]non-5-ene acetate was identified as excellent cellulose solvent allowing for a rapid dissolution at moderate temperatures and subsequent shaping into continuous filaments. The highly oriented cellulose fibers obtained upon coagulation in cold water exhibited superior tenacity, exceeding that of commercial viscose and NMMO-based Lyocell (Tencel) fibers. The respective staple fibers, which have been converted into two-ply yarn by ring spinning technology, presented very high tenacity. Furthermore, the Ioncell yarn showed very good behavior during the knitting and weaving processes, reflecting the quality of the produced yarn. The successfully knitted and woven garments from the Ioncell yarn demonstrate the suitability of this particular ionic liquid for the production of man-made cellulosic fibers and thus give a promising outlook for the future of the Ioncell-F process.

    Effect of bioactive extruded PLA/HA composite films on focal adhesion formation of preosteoblastic cells2014Ingår i: Colloids and Surfaces B: Biointerfaces, ISSN 0927-7765, E-ISSN 1873-4367, Vol. 121, s. 409-416Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The quality of the initial cell attachment to a biomaterial will influence any further cell function, including spreading, proliferation, differentiation and viability. Cell attachment is influenced by the material's ability to adsorb proteins, which is related to the surface chemistry and topography of the material. In this study, we incorporated hydroxyapatite (HA) particles into a poly(lactic acid) (PLA) composite and evaluated the surface structure and the effects of HA density on the initial cell attachment in vitro of murine calvarial preosteoblasts (MC3T3-EI). Scanning electron microscopy (SEM), atomic force microscopy (AFM) and infrared spectroscopy (FTIR) showed that the HA particles were successfully incorporated into the PLA matrix and located at the surface which is of importance in order to maintain the bioactive effect of the HA particles. SEM and AFM investigation revealed that the HA density (particles/area) as well as surface roughness increased with HA loading concentration (i.e. 5, 10, 15 and 20wt%), which promoted protein adsorption. Furthermore, the presence of HA on the surface enhanced cell spreading, increased the formation of actin stress fibers and significantly improved the expression of vinculin in MC3T3-E1 cells which is a key player in the regulation of cell adhesion. These results suggest the potential utility of PLA/HA composites as biomaterials for use as a bone substitute material and in tissue engineering applications.

    High-strengthelectrically conductive fibers: Functionalization of polyamide, aramid andpolyester fibers with PEDOT polymer2017Ingår i: Polymers for Advanced Technologies, ISSN 1042-7147, E-ISSN 1099-1581Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In this work, high-performance fibers such as aramid (Twaron), polyamide (PA6), polyester (PET), and hybrid Twaron/PA6 fibers were transformed into electroactive fibers by coating them with conjugated polymer, poly(3,4-ethylenedioxythiophene) (PEDOT) through vapor phase polymerization (VPP) method. The VPP is considered as an efficient technique for depositing CPs on different substrates regardless of their lower solubility in various solvents. In this paper, PEDOT-coated high-performance fibers were prepared under already optimized reaction conditions, and then a comparison between electrical, thermal, and mechanical properties of different fibers, before and after coating, was made. The obtained coated fibers were characterized through scanning electron microscope (SEM), thermogravimetric analysis (TGA), 2-probe electrical resistance measurement method, and tensile testing. It was revealed that at particular reaction conditions, all high performance textile substrates were successfully converted into electroactive fibers. The voltage-current (V-I) characteristics showed that PEDOT-coated polyester fibers exhibited highest conductivity value among all other substrate fibers. The active PEDOT layers on high performance fibers could behave as an antistatic coating to minimize the risks associated with static charges at work places. Also, the obtained fibers have potential to be used as smart materials for various medical, sports, and military applications.

    The Co-design Process in Mass Customization of Complete Garment Knitted Fashion Products2016Ingår i: Journal of Textile Science & Engineering, E-ISSN 2165-8064, Vol. 6, nr 4, s. 1-8Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Complete garment knitting technology is a method of producing products, generally fashion garments, readymade directly in the knitting machine without operations such as cutting and sewing. This makes it possible to manufacture a fashion garment with fewer processes then with conventional methods. Mass customisation is a customer co-design process of products and that tries to meets the needs of an individual customer's demand. The customer can order a garment with a customised style, colour, size, and other personal preferences. Co-design is a collaborative process between the customer, the retailer, and the manufacturer by which a product is customised to fulfil the customer's requirements. This paper is based on the results of a doctoral thesis. The process of codesign and manufacture of a customised complete fashion product is examined. Research was conducted by a retail concept simulation and three case studies. A cross-case analysis was done to analyse the data. The main findings are a description of two kinds of retail concepts for knitted customized fashion products. A knitted garment can be customized, produced, and delivered to the customer in three to five hours. In the Co-design process two kinds of interactions are feasible between the company and the customer: manual or digital co-design. A manual process has advantages such as: high service level for customers, no requirement of advanced technical equipment. However, manual co-design is labour intensive, a shop assistant can only serve one client at a time. It is also only pplicable to brick-and-mortar stores and not transferable to the Internet. Digital codesign, on the other hand, encourages customers to do the customisation on their own, without the aid of sales personnel and little risk of queues. Moreover, this technique is ideal for the Internet. Disadvantages to date have included limited design options and problem of taking body measurements.

    Knittability of fibres with high stiffness2000Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    Knitting techniques and machinery are extensively used for the production of textile products for garmet and industrial use. Knitting is also gaining importance for composite materials performing. Basically two principles are in use. i) Weft knitting gives structures of for example traditional sweaters types suitable for structures taking impact loads. ii) Warp knitting gives the traditional tricot structures and the non crimped insert yarn DOS-fabrics extensively used for composite materials fabrication. In the knitting process do hooked needles pick up yarns and form closed loops. The stability of the loop formation depends on the bending of the fibres and type of friction on the needles during the different stages of the knitting process. The characteristics of static friction when the yarn is drawn by the needles into the machine, sliding friction in the loop formation and release after loop formation are of vital importance for the final product. The complexity of the yarn behaviour, the far from ideal mechanical and tribological behaviour of the fibres are mastered by many knitters. The history of knitting indicate the same kind of phenomena as indicated by the history of the steam engine: ”Science owes more to the steam engine than the steam engine owes to science”, lord Kelvin. The knitting process has however been modelled from first principles using models for friction of fibres on positively curved surfaces and simultaneous plastic deformation. A method and fixtures based on earlier work by Andersson et.al adopted for tests of the stress build up in fibres on knitting needles in order to study the knitting process in a tensile testing machine have been developed. Monofilaments and high modulus multifilament yarns known for giving difficulties in knitting process have been studied with respect to : – Static friction – Bending radius of the fibre during the process – Adhesion to needle at the end contact – Sliding friction Plain knitted fabrics and symmetric spacer fabrics have been produced of monofilament and multifilament nylon, PET and aramides. Analysis of fabrics in compression is going on.

    Kreativitet vs Kapital: Användningen av innovativa marknadsföringsmetoder hos svenska modeföretag2015Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    År 2013 var den globala omsättningen för modeindustrin ca 76 tusen miljarder svenska kronor (Office of Textiles and Apparel, 2014). Bara i Sverige omsattes det 229 miljarder svenska kronor år 2012 inom denna sektor, en ökning på 11 % från föregående år (Tillväxtverket, 2014). Att modebranschen är under ständig utveckling och ökar i tillväxt kan man se då dessa siffror stiger varje år. Statistik från 2014 visar att trots denna ökning så överlever endast 47 % av nystartade modeföretag de tre första åren (Statistic Brain, 2014). Så hur lyckas man som modeföretag i early stage-fasen att med begränsade resurser stärka sitt varumärke och hålla sig kvar på marknaden? I denna studie berörs olika delar så som traditionell marknadsföring, okonventionell marknadsföring, branding samt transparens, där huvudfokus ligger på företag i early stage- fasen av sin uppstart. I uppsatsen genomfördes sju intervjuer med svenska modeföretag som är eller nyligen varit i denna fas för att få ett resultat med så hög validitet som möjligt. Brist på kunskap och kapital är inte ovanligt i denna bransch och med ökad medvetenhet hos konsumenter om de olika processerna, så kan det ibland uppstå svårigheter att försvara sig som nystartat företag. Då modebranschen är i ständig rörelse med stora förändringar från säsong till säsong måste man som nytt företag vara beredd på reformation samt att alltid tänka innovativt. Det är även viktigt att vara uppmärksam på kommande och rådande trender gällande alla aktiviteter ett företag arbetar med. Eftersom olika marknadsföringsstrategier både kan hjälpa och stjälpa ett varumärkes position på marknaden är den stora utmaningen att hitta rätt metod för just sitt företag (Easy, M. 2009). Resultatet av denna studie kommer alltså att bygga på de kvalitativa intervjuer som genomförts med de utvalda företag som har valt att medverka. De beskriver hur deras uppstart sett ut när det kommer till branding samt hur de i olika kanaler väljer att marknadsföra sig. I dessa intervjuer tittar vi även närmare på hur de lyckades starta sin verksamhet och vilka kapitalmedel de använt, deras syn på okonventionell marknadsföring samt hur marknadsföring och branding hänger samman.

    Performance of biocomposites from surface modified regenerated cellulose fibers and lactic acid thermoset bioresin2015Ingår i: Cellulose (London), ISSN 0969-0239, E-ISSN 1572-882XArtikel i tidskrift (Refereegranskat)
    Abstract [en]

    The effect of surface treatments, silane and alkali, on regenerated cellulose fibers was studied by using the treated fibers as reinforcement in lactic acid thermoset bioresin. The surface treatments were performed to improve the physico–chemical interactions at the fiber–matrix interface. Tensile, flexural and impact tests were used as indicator of the improvement of the interfacial strength. Furthermore, thermal conductivity, viscoelasticity measurements as well as microscopy images were made to characterize the fiber surface treatments and the effect on adhesion to the matrix. The results showed that silane treatment improved the mechanical properties of the composites as the silane molecule acts as link between the cellulose fiber and the resin (the fiber bonds with siloxane bridge while the resin bonds with organofunctional group of the bi-functional silane molecule) which gives molecular continuity in the interphase of the composite. Porosity volume decreased significantly on silane treatment due to improved interface and interlocking between fiber and matrix. Decrease in water absorption and increase in contact angle confirmed the change in the hydrophilicity of the composites. The storage modulus increased when the reinforcements were treated with silane whereas the damping intensity decreased for the same composites indicating a better adhesion between fiber and matrix on silane treatment. Thermogravimetric analysis indicated that the thermal stability of the reinforcement altered after treatments. The resin curing was followed using differential scanning calorimetry and the necessity for post-curing was recommended. Finite element analysis was used to predict the thermal behavior of the composites and a non-destructive resonance analysis was performed to ratify the modulus obtained from tensile testing. The changes were also seen on composites reinforced with alkali treated fiber. Microscopy images confirmed the good adhesion between the silane treated fibers and the resin at the interface.

    Compression-recovery model of absorptive glass mat (AGM) separator guided by X-ray micro-computed tomography analysis2017Ingår i: Journal of Power Sources, ISSN 0378-7753, E-ISSN 1873-2755, Vol. 365, s. 389-398Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Absorptive glass mat (AGM) separators play a key role in enhancing the cycle life of the valve regulated lead acid (VRLA) batteries by maintaining the elastic characteristics under a defined level of compression force with the plates of the electrodes. Inevitably, there are inherent challenges to maintain the required level of compression characteristics of AGM separators during the charge and discharge of the battery. Herein, we report a three-dimensional (3D) analytical model for predicting the compression-recovery behavior of AGM separators by formulating a direct relationship with the constituent fiber and structural parameters. The analytical model of compression-recovery behavior of AGM separators has successfully included the fiber slippage criterion and internal friction losses. The presented work uses, for the first time, 3D data of fiber orientation from X-ray micro-computed tomography, for predicting the compression-recovery behavior of AGM separators. A comparison has been made between the theoretical and experimental results of compression-recovery behavior of AGM samples with defined fiber orientation characteristics. In general, the theory agreed reasonably well with the experimental results of AGM samples in both dry and wet states. Through theoretical modeling, fiber volume fraction was established as one of the key structural parameters that modulates the compression hysteresis of an AGM separator.

    Creating three-dimensional (3D) fiber networks with out-of-plane auxetic behavior over large deformations2017Ingår i: Journal of Materials Science, ISSN 0022-2461, E-ISSN 1573-4803, Vol. 52, nr 5, s. 2534-2548Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Fiber networks with out-of-plane auxetic behavior have been sporadically investigated. One of the major challenges is to design such materials with giant negative Poisson’s ratio over large deformations. Here in, we report a systematic investigation to create three-dimensional (3D) fiber networks in the form of needlepunched nonwoven materials with out-of-plane auxetic behavior over large deformations via theoretical modeling and extensive set of experiments. The experimental matrix has encapsulated the key parameters of the needlepunching nonwoven process. Under uniaxial tensile loading, the anisotropy coupled with local fiber densification in networks has yielded large negative Poisson’s ratio (up to −5.7) specifically in the preferential direction. The in-plane and out-of-plane Poisson’s ratios of fiber networks have been predicted and, subsequently, compared with the experimental results. Fiber orientation was found to be a core parameter that modulated the in-plane Poisson’s ratio of fiber networks. A parametric analysis has revealed the interplay between the anisotropy of the fiber network and the out-of-plane Poisson’s ratio based upon constant volume consideration.

    Vikten att följa trender - en inköpares dilemma?: En tvärsnittsstudie om beslutsfattandet inom svenska modeföretags inköpsprocesser2014Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Sedan millenniumskiftet förändrades modevärlden radikalt av fler säsonger, ökad mångfald av trender samtidigt som trendernas livslängds blev allt kortare. Hos inköparna på de stora klädbolagen ställs det idag ett allt större krav att veta vad som kommer att sälja i framtiden. Idag måste besluten tas snabbt så att kläderna hinner producera och levereras i tid innan modet hinner ändra sig. Som ett hjälpmedel för inköpare och designers om i vilken riktning modet kommer att gå finns trender som fungerar som ett avgränsat modeuttryck för att förmedla och tolka en viss stil och därmed ge en tydlig bild om vad som bör produceras och efterfrågas. Men eftersom internet har medfört en ökad acceleration av trender kan det upplevas svårt att veta vad som kommer sälja i framtiden och det är här ser vi trendbyråernas roll. Trendbyråer har en koordinerande roll på marknaden där de ger företag vägledning om förändringar i modet. Genom trendanalyser får företag en överblick hur riktningen i modet kommer att gå, förstå vilka globala influenser som påverkar modet och en reflektion kring hur allt återspeglas till modet. Vad gäller tidigare forskning av begreppen trender och trendbyråer vid beslutsfattande, har ingen omfattande undersökning tidigare gjorts vilket har medfört att vår uppsats känns värdefull för en mer förståelse kring ämnet. Avsikten med vår uppsats är att undersöka och analysera hur trender och trendanalyser har för betydelse vid beslutsfattande inom inköpsprocessens tidiga stadium hos svenska modeföretag. Studien har efter insamling av teori inom områdena beslut, trender och trendanalyser genomförts med en kvalitativ grund där insamling av det empiriska materialet har utgått från semistrukturerade intervjuer. Intervjuer har främst genomförts med respondenter som innehar en roll inom inköp på svenska modeföretag som ingår i beteckningen SME (Small medium Enterprises). Dessa företag är Ellos, Lindex, Gina Tricot och MQ. För att öka förståelsen kring trender och trendanalyser har intervjuer även genomförts med en trendanalytiker från Svenska Moderådet och en författare bakom boken Trendmakarna. Insamlad data har därefter analyserats och ställts mot teorier angående beslut, trender och trendanalyser i syfte att kunna uttala oss om hur inköpare ser på trender och trendbyråers betydelse vid beslutsfattande av inköp. De resultat som empirin bestått av ger indikationer på att trender har en betydande roll men att det både kan öka och minska på osäkerheter samt risker. Inköparna anser att det finns många risker med trendbaserade produkter men att trendanalyser vid beslutsfattande kan användas för att förstå riktningen modet går i för att därefter kunna anpassa inköpen genom volym, budget, material och leverantörer. Därmed kan de vara ett hjälpmedel för att minska på både ett besluts risk och osäkerhet, vilket bekräftar de teorier som tagits upp. Dock kan vi uttala oss om att beslutsfattande inom inköp inte bara baseras på trendanalyser utan andra faktorer och variabler spelar också in.

    Single-step disperse dyeing and antimicrobial functionalization of polyester fabric with chitosan and derivative in supercritical carbon dioxide2019Ingår i: Journal of Supercritical Fluids, ISSN 0896-8446, E-ISSN 1872-8162, Vol. 147, s. -240Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In this study, a novel green approach was adopted to develop antimicrobial polyester fabric using sustainable biopolymers (chitosan/derivative) as eco-friendly antimicrobial agents via the resource efficient supercritical CO2 (scCO2) dyeing route in a single step. Polyester fabric was dyed with a small amount of dye (0.4% owf) in the presence of chitosan/derivative (3% owf) in scCO2 at 120 °C, 25 MPa for 1 h. The success of chitosan/derivative impregnation was confirmed by Fourier Transform Infrared (FTIR), Zeta Potential (ζ), Scanning Electron Microscopy (SEM), and Water Contact Angle (WCA) measurements. According to the result, excellent color strength and fastness properties were obtained and the treated samples also reduced 75 − 93% of Escherichia coli (ATCC 25922) bacteria within one hour. This suggests that the dye and chitosan/derivative had no adverse effect on each other, proving compatibility. This new approach would help to reduce the cost of production and environmental pollution associated with the conventional textile finishing processes.

    Combined Pre-treatment and Causticization of cotton fabric for improved dye uptake2017Ingår i: Advance Research in Textile Engineering, ISSN 2572-9373, Vol. 2, nr 1, artikel-id 1016Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Conventionally, cotton fabric is subjected to a series of separate pretreatment processes such as desizing, scouring, and bleaching to remove natural and added impurities for satisfactory dyeing and finishing. When the sole purpose is to improve the dye uptake, cotton fabric is subjected to yet another separate process called causticization, a treatment of cotton fabric at reduced concentration of caustic soda (110-150 g/L) compared to mercerization. All these processes i.e. desizing, scouring, and bleaching are lengthy and require large amount of water, energy, chemicals, and time which lead to increase in cost and productivity loss.

    In this paper, a combined desizing, scouring, bleaching and causticization process with shorter processing time is reported. Single factor randomized experimental design was used for process optimization. Based on experiments, the optimum recipe consisted of padding the gray cotton fabric using a twodip, two-nip technique in a bath containing NaOH 140g/L; Sodium Per Borate (SPB) 40-45g/L; wetting agent 1g/L, batching for 30 min at room temperature and washing the treated fabric with 1g/L emulsifier twice for 15 minutes each at boil with 3% owf SPB added during the second wash, rinsed with hot and cold water and air dried.

    The results showed excellent wettability, good degree of whiteness, minimum loss of tensile strength and higher dye uptake compared to uncausticized commercially bleached cotton fabric.

    Supercritical CO2 technology in resource effective textile production of functional textiles2017Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    Supercritical CO2 (SC-CO2) textile processing is a water-free technology with significant savings in energy, chemicals, and wastewater while producing high-quality products thereby creating new business opportunities. It is an attractive alternative to both water and organic solvent since it is inexpensive, essentially nontoxic, nonflammable, environmentally friendly and requires relatively low critical temperature 310c and pressure 7.38 Mpa which can easily be recaptured and recycled after use.

    Today supercritical CO2 dyeing of PET has come up to the commercial level. The Netherlands-based company, DyeCoo Textile Systems, was the first to launch commercial SC-CO2 dyeing system. Meanwhile, SC-CO2 is a resource efficient, flexible, and ecological textile production which could be a suitable technology for textile functionalization. However, there are limited studies on the potential use of this technology for the production of smart and functional textiles. Furthermore, unlike dyes, fundamental understanding of the solubility and transport (kinetics) properties of functional compounds is lacking.

    The aim of this research project is to develop sustainable functional and smart textile materials using SC-CO2 technology. It will focus on combined dyeing and functionalization (antimicrobial, medical/care, and flame retardant) of woven and knitted synthetic textiles using SC-CO2. Preliminary experiments have been conducted to develop antimicrobial polyester fabric in SC-CO2 and a promising result is found. Furthermore, characterization of the functionalized fabric (surface property, wettability), the release kinetics of active principles from textiles (Franz cell device, HPLC) and the skin physiology after the contact with a functionalized fabric (cutometer) will be investigated.

    Comparison of the photochromic behaviour of dyes in solution and on polyester fabric applied by supercritical carbon dioxide2019Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    Photochromic textiles are of considerable interest for smart and functional textile applications due to their remarkable dynamic colour changing effect when irradiated with light of a certain wavelength. The use of resource efficient processes, such as digital inkjet printing and supercritical carbon dioxide (scCO2) dyeing techniques enables an economic production of those high-end functional products with high material costs. In this study, photochromic polyester fabric has been prepared by applying two commercially important photochromic dyes from spirooxazine (SO) and naphthopyran (NP) dye classes using scCO2-dyeing technique. The properties of scCO2 dyed photochromic fabrics were compared with the properties of the same dyes in a non-polar solvent, hexane. UV-Vis spectroscopy and a specially designed online colour measurement system capable of simultaneous UV irradiation and colour measurement were used to evaluate the photochromic colour behaviour. Both photochromic dye types embedded in textile as well as in solution showed significant reversible colour changing properties when exposed to UV light and revert to their original non-coloured form when the UV light is removed. The scCO2 dyed polyester fabrics exhibited similar trends of colour build-up as in solution, while contrasting behaviour was observed in terms of colour changing rates compared to their behaviour in solution.

    Effect of liquid immersion of PEDOT:PSS-coated polyester fabric on surface resistance and wettability2017Ingår i: Smart materials and structures (Print), ISSN 0964-1726, E-ISSN 1361-665X, Vol. 26, s. 1-7, artikel-id 065016Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Coating of textile fabrics with poly (3, 4-ethylenedioxythiophene): poly (styrene sulfonate) (PEDOT:PSS) is one of the methods used for obtaining functional or smart applications. In this work, we prepared PEDOT:PSS polymer with certain additives such as polyethylene glycol (PEG), methanol (MeOH), and ethylene glycol (EG) on polyester fabric substrates by a simple immersion process. Surface resistance was measured and analyzed with analysis of variance to determine the coating parameters at 95% confidence level. Fourier Transform Infrared (FTIR) analysis and Scanning Electron Microscopy (SEM) study of the samples were performed. Contact angle and washing fastness measurements were conducted, to observe the wettability and washing fastness of the samples, respectively. Surface resistance values were decreased by a factor of 100, due to conductive enhancers. As the immersion time and temperature condition varies, surface resistance showed no difference, statistically. FTIR analysis supports the idea that the mechanism responsible for the conductivity enhancement is the partial replacement of PSS from PEDOT chain by forming a hydrogen bond with hydroxyl ion (OH) of the conductive enhancers. A SEM images showed that PEDOT:PSS is well distributed to the surface of the fabrics. Contact angle measurements showed morphology change in the samples. The conductivity was reasonably stable after 10 washing cycles. Altogether, an effective simple immersion of coated polyester fabric is presented to achieve functional textiles that offer a broad range of possible applications.

    Electromechanical properties of polyamide/lycra fabric treated with PEDOT:PSS2017Ingår i: Electromechanical properties of polyamide/lycra fabric treated with PEDOT:PSS, Institute of Physics (IOP), 2017, Vol. 254, s. 072025-Konferensbidrag (Refereegranskat)
    Abstract [en]

    One of the challenges in smart textiles is to develop suitable multifunctional materials that can address simultaneously several characteristics such as durability, stretchability, lightweight, and conductivity. Conductive polymers which showed success in different technological fields like polymer solar cells and light emitting diodes are promising in many smart textile applications. In this work, we treated a common polyamide/lycra knitted fabric with PEDOT:PSS for stretchable e-textiles. PEDOT:PSS, with DMSO as a conductivity enhancer and different ratios of water-based polyurethane dispersions as a binder, was applied to the fabric with simple immersion and coating applications. The effect of different application methods and binder ratio on the surface resistance of the fabric was monitored with four point probe electrical surface resistance measurement systems. Samples prepared by immersion technique are more uniform and have higher conductivity than those prepared by a coating technique. SEM images showed that PEDOT:PSS is incorporated into the structure in the immersion method while in the coating it is majorly present on the surface of the fabric. The tensile measurement showed that the acidic PEDOT:PSS and polyurethane dispersion coating has no adverse effect on the tensile strength of the fabric. The coated samples can be stretched up to 700% while still reasonably conductive. The resistance increases only by a small amount when samples were stretched cyclically by stretching 100%. Generally, samples prepared by the immersion method maintained better conductivity while stretching than those by a coating method. The washing fastness of the samples was also assessed.

    New Product Forecasting with Structured Analogy Method in the Fashion Industry: Case Studies with the Fashion Footwear Products2015Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Fashion and the contemporary environment as a whole, is a complex environment that requires retailers and wholesalers to adapt to the changes that constantly occurring. This adaptation is in a bid to ensure that more profits than loses are realized by the company. For this reason, companies have to use various methods to determine the best ways to improve their products. Companies resolve to introduction of new product to the market but the acceptance of new products to the fashion industry is not an assured factor but rather a gamble. This is mainly because of the industry’s characteristics. The main aim of this thesis is to analyze the methods that may be used to improve the accuracy of new products. The fashion industry has characteristics that may be considered as challenges because for instance, when a product is launched, one has to determine whether it is by a reputable designer or whether it is a trend, and with the fashion industry, trends are mainly turned into such by celebrities who introduce a certain design to the world for adoption. These challenges or characteristics are carefully analyzed and examined with the necessity of the introduction of new products analyzed. Data collection, being the main backbone of this thesis and multiple-case study method, is used to answer the research question as “How can structured analogy method be used to improve the forecast accuracy for the footwear products in the fashion industry “.Samples for case study have been chosen from footwear category. Structured analogy method is used to determine the accuracy of the information gathered from literature review.
