Abstract [en]

Sensory investigations of the functional textiles could be an alternative for the quality-inspection and control of the products. The purpose of this research is to use subjective evaluation technique for assessing the tactile comfort of some functional textile fabrics based on AATCC Evaluation procedure 5-2011. Blind subjective evaluations and visual subjective evaluations were performed for sensory investigation. Ten fabric-skin-contact and comfort-related sensory properties were used to evaluate the handle of the functional textile fabrics. The reliability of the sensorial data obtained by subjective tests was evaluated using statistical data analysis techniques. A minimum and maximum consensus distance recorded were 0.58 and 1.61, respectively, using a descriptive sensory panel analysis and prove the consistency and similar sensorial perception between panelists. The Pearson correlation coefficient between panelists was up to 96% and hence a strong agreement between the panelist’s judgment. The results allowed to consider the subjective evaluation using a panel of experts could be validated in the case of functional fabrics. For functional textiles, additional visual subjective evaluation should be considered to have a similar human perception in addition to blind subjective evaluation.

Abstract [en]

Hospital-acquired infections have become a major challenge which threaten the hospitalized patients’ safety. The presence of nosocomial pathogens is generally reported in connection with solid surfaces near patient environments. These surfaces become significant sources of transmission and lead most often to the contamination and cross-contamination of nosocomial pathogens to the patients and staff. This paper investigates strategies to apply beneficial bacteria on viscose-based nonwoven wipes and the viability of these beneficial bacteria on the wipes along with characterization of the physical properties of the wipes. Major findings include that it is possible to produce dry wipes which contain an adequate number of beneficial bacteria or spores. After these wipes are wetted, they can release a certain number of bacteria from the wetted wipes. These released beneficial bacteria can inhibit pathogens by growing and colonizing on the wiped surfaces.

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.

Abstract [en]

Conductive elastic fabrics are desirable in wearable electronics and related applications. Highly elastic conductive polyamide/lycra knitted fabric was prepared using intrinsically conductive polymer poly (3, 4-ethylenedioxythiophene) (PEDOT) blended with polyelectrolyte poly (styrene sulfonate) (PSS) using easily scalable coating and immersion methods. The effects of these two methods of treatments on uniformity, electromechanical property, stretchability, and durability were investigated. Different grades of waterborne polyurethanes (PU) were employed in different concentrations to improve the coating and adhesion of the PEDOT:PSS on the fabric. The immersion method gave better uniform treatment, high conductivity, and durability against stretching and cyclic tension than the coating process. The surface resistance increased from ~1.7 and ~6.4 Ω/square at 0% PU to ~3.7 and ~12.6 Ω/square at 50% PU for immersion and coating methods, respectively. The treatment methods as well as the acidic PEDOT:PSS did not affect the mechanical properties of the fabric and the fabric show high strain at break of ~650% and remain conductive until break. Finally, to assess the practical applicability of the treated fabric for wearable e-textiles, the change in surface resistance was assessed by cyclically stretching 10 times at 100% strain and washing in a domestic laundry for 10 cycles. The resistance increases only by a small amount when samples were stretched cyclically at 100% strain and the samples show good durability against washing.

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.

Abstract [en]

Despite their chemical inertness and poor hydrophobicity, carbon-based materials are widely used in electrochemical applications due to their robustness, good electrical conductivity and corrosion resistance. The purpose of the work carried was to increase the wettability of nonwoven carbon fiber felts for improved efficiency in bio/electrochemical applications. Virgin Carbon Felt (VCF) was first treated with cold remote plasma (CRP) using a mixture of nitrogen and oxygen (1 or 2 %) as plasma gas.  Bio-functionalization of the carbon felts with glucose oxidase (GOx) enzyme was then carried using physical adsorption method. FTIR and XPS analysis showed an integration of new oxygenated functional groups (C-O and C=O) as well as amines and amides on the surface of VCF treated by the CRP treatment, which improved the wettability of the samples. Capillary uptake increased from around 0 % (for VCF) to nearly 750 % with 2 % oxygen in plasma gas. GOx enzyme showed higher activity after immobilization at pH 5.5 on the CRP treated samples, maintaining up to 50 % of its initial enzymatic activity after six cycles while with the VCF, no enzymatic activity was observed after the fourth cycle. These obtained felts can be used as electrodes in sustainable bioprocesses.

Abstract [en]

Subjective and objective evaluations of the handle of textile materials are very important to describe its tactile comfort for next-to-skin goods. In this paper, the applicability of artificial neural network (ANN) and adaptive neuro-fuzzy inference system (ANFIS) modeling approaches for the prediction of the psychological perceptions of functional fabrics from mechanical properties were investigated. Six distinct functional fabrics were evaluated using human subjects for their tactile score and total hand values (THV) using tactile and comfort-based fabric touch attributes. Then, the measurement of mechanical properties of the same set of samples using KES-FB was performed. The RMSE values for ANN and ANFIS predictions were 0.014 and 0.0122 and are extremely lower than the variations of the perception scores of 0.644 and 0.85 forANN and ANFIS, respectively with fewer prediction errors. The observed results indicated that the predicted tactile score and are almost very close to the actual output obtained using human judgment. Fabric objective measurement-technology, therefore, provides reliable measurement approaches for functional fabric quality inspection, control, and design specification.

Abstract [en]

In this paper, an overview of the bio-Fenton and bio-electro-Fenton processes for sustainable wastewater treatment is provided. These two methods have been used in recent years to treat many kinds of persistent pollutants while maintaining the sustainability in materials and power consumption compared to conventional methods, through efficient eco-designed systems. The different kinds of electrodes used for the bio-electro-Fenton are reviewed, along with the influencing factors affecting the efficiency of these methods, and the different designs used to construct the reactors. Moreover, the various organic pollutants from industrial sources, like effluents from textile and pesticides facilities, treated using these processes are also reported. However, the main challenge facing these technologies is to improve their performance, stability and lifetime to achieve more sustainable and cost-effective wastewater treatment on pilot and large scales. Hence, future perspectives and trends are discussed to overcome the drawbacks of these methods.
