Abstract [en]

Highly oxidation tendency of zerovalent iron nanoparticles limits itsvarious practical applications. In this work, stabilization of zerovalent ironnanoparticles (nZVI) in 3-Mercapto-1,2-propanediol (α-thioglycerol, α -TG)modified polyester nonwoven (PN) for improved catalytic and antibacterialapplication has been studied for the first time. Changes in wettability as wellas structural, morphological, thermal and catalytic properties of the resultingPN/α -TG/nZVI material were investigated by scanning electron microscopy,energy dispersive X-Ray, zeta potential measurements, thermogravimetricanalysis, differential scanning calorimetry, fourier transform infrared and UV–visible spectroscopies. Prior to functionalization, hydrophilic functional groupshave been introduced in PN surface by air atmospheric plasma treatment.Iron nanoparticles were immobilized by α-thioglycerol on the polyester fiberswith a multi-meter particle size. α -TG stabilized nZVI by reducing thetendency of easy oxidation. nZVI insertion resulted in high thermal stability ofPN. As an application, PN/α-TG/nZVI exhibited an excellent catalytic activityin the reduction of 4-nitrophenol with appreciable recyclability. The resultsfurther demonstrate that PN/α-TG/nZVI can be employed not only for toxiccompounds removal but also to inhibit the growth of bacteria at normalconditions which herein open new prospects for concrete industrialapplications of nZVI based multifunctional systems.

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]

Dispersion of iron nanoparticles (Fe-NPs) was achieved on polyester fabrics (PET) beforeand after incorporation of dendrimers (PAMAN), 3-(aminopropyl) triethoxysilane (APTES) orthioglycerol (SH). The catalytic activity of the resulting materials (PET-Fe, PET-PAMAM-Fe,PET-APTES-Fe and PET-SH-FE) was comparatively investigated in the degradation of 4-nitrophenol(4-NP) and methylene-blue (MB. Full characterization through diverse instrumentalmethods allowed correlating the type of the organic moiety incorporated to the Fe content,catalytic properties and stability. The highest 4-NP degradation yield reached 99.6 % in 12 minsfor PET-SH-Fe. The catalytic activity was explained in terms of reactant interaction with Fe-NPs. The 1st order reaction kinetics and pseudo-1st order adsorption kinetics provide evidenceof the key-role of reactant adsorption. These findings allow envisaging the preparation of fiberbasedcatalysts for potential uses in environmental and green chemistry.

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]

This study reports the synthesis, immobilization and stabilization of multiscale zero valent iron (Fe0=ZVI)particles on fibrous polyester (PET) nonwoven membrane for heterogeneous Fenton-like removal of hazardouspollutants in water. Activation of PET fiber surface by air atmospheric plasma with or without a consecutivegrafting of hyperbranched poly-(ethylene glycol)-pseudo generation 5 dendrimer having hydroxyl (-OH) endgroup functionality created polar reactive functional groups allowing immobilization and stabilization of ZVIparticles. Synthesis of ZVI was carried out through chemical reduction of ferric ions, either through a single stepin-situ, or a two-step ex-situ reduction-immobilization method. The nonwovens were characterized usingwettability, Fourier transform infrared spectroscopy (FTIR), optical microscopy, scanning electron microscopy(SEM), X-ray energy-dispersive spectroscopy (EDS), X-ray diffraction (XRD) and thermo-gravimetric analysis(TGA). Results confirmed the formation and immobilization of nano to sub-micronic multi-scale ZVI particles.The particle size, distribution and stability of ZVI were found to be influenced by the methods of ZVI synthesisand PET surface activation used. The ZVI particles initially formed, quasi-instantaneously turned to yellowishbrown indicating the formation of oxide layer, except in the case of dendrimer grafted PET, where higher content(22.30%) and stability of ZVI was detected. All ZVI immobilized nonwovens exhibited high effectiveness towardsFenton-like degradation of malachite green dye (20 ppm), with fastest color removal (98% in 20 min) achievedby dendrimer/ex-situ nonwoven. This nonwoven could be used up to eight repeated cycles providing low TDS (52 ppm) and high COD reduction (66.23%). Combined use of eco-friendly plasma and dendrimer grafting,provides efficient fibrous textile base heterogeneous catalysis.
