Underwater plasma discharge is used for surface activation of polypropylene nonwoven fabrics with subsequent immobilisation of silver or copper. Plasma generated at atmospheric pressure is preferred as this is a low cost and environmental considerate technique in comparison with other techniques. At the same time, the antibacterial properties of silver and copper are well known. The underwater ...

A short review with 49 references describes the electrospinninng (ES) process for polysaccharides, cellulose and chitosan, and their derivatives, including cellulose acetate and hydroxypropyl cellulose. A majority of applied studies adopted a two step-process, in which the cellulose acetate was used for the first ES process, followed by acetyl group removal to regenerate cellulose thin fibers. ...

| Cloudiness constitutes an important quality parameter of nonwoven fabrics. We show that it can be graded using a speciic Laplacian pyramid decomposition which has to be modiied at the boundaries. An algorithm is presented which calculates a quality measure as a weighted mean of the variances at all pyramid levels, where the weights are adapted to the human perception of cloudi-ness. The obtai...

The main limitation preventing the use of enzymatic cellulosic ethanol in industrial production is its higher cost which is mainly due to the elevated price of β-glucosidase (BG). Herein, we report on a simple strategy for the in-situ encapsulation of BG for repeated cellulosic ethanol production. In this strategy, BG was net-immobilized into a poly(ethylene glycol) (PEG) net-cloth layer on a P...

In this study, cotton spunlace nonwoven fabrics with four different basis weights were coated graphene oxide (GO) by conventional dip coating method which is one of the most simple and effortless process in textile industry. The immersed an aqueous sodium dithionite solution order to obtain reduced (RGO) fabrics. obtained became electrically conductive very low surface electrical resistivity 5....

Textile materials are good carriers of various types of micro organisms and can cause health related problems to the wearer. Application of natural antimicrobial agents on textile dates back to antiquity, when the ancient Egyptian used. Herbs were used to inhibit the growth of bacteria on textiles. Silver is a renowned antimicrobial agent used on textiles from very ancient time till date. A ver...

Upon the outbreak of COVID-19, community wide mask wearing has become an important tool to prevent spread virus. The use disposable masks -that are generally produced three or more layers synthetic nonwovens- by general public is being questioned from environmental and waste perspective. Conventional textile fabrics, on other hand, may not provide desired level protection against In this study ...
