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]

Wearable Electrocardiography (ECG) sensing textiles have been widely used due to their high flexibility, comfort, reusability and the possibility to be used for home-based and real-time measurements. Textile electrodes are dry and non-adhesive, therefor unlike conventional gel electrodes, they don't cause skin irritation and are more user-friendly especially for long-term and continuous monitoring outside the hospital. However, the challenge with textile electrodes is that the quality and reliability of recorded ECG signals by smart garments are more sensitive to different factors such as electrode placement, skin humidity, user activities and contact pressure. This review will particularly focus on the research findings regarding the influence of electrode placement on the quality of biosignal sensing, and will introduce the methods used by researchers to measure the optimal positions of the electrodes in wearable ECG garments. The review will help the designers to take into account different parameters, which affect the data quality, reliability and comfort, when selecting the electrode placement in a wearable ECG garment.
