Fiber fragments are one of the dominant types microplastics in environmental samples, suggesting that synthetic textiles a potential source to environment. Whereas release during washing is already well studied, much less known about abrasion processes. The may induce fibrillation fibers and therefore result formation finer fiber fragments. aim this study was investigate influence on microplast...

This thesis describes strategies for and examples of cellulose fiber modification. The ability of an engineered biocatalyst, a cellulose-binding module fused to the Candida antarctica lipase B, to catalyze ring-opening polymerization of εcaprolactone in close proximity to cellulose fiber surfaces was explored. The water content in the system was found to regulate the polymer molecular weight, w...

in this research, old magazine (omg) recycled fiber and glass fiber (gf) were mixed at different levels of 10%, 20%, 30% and 40% (based on weight) with two levels of 50% and 60% polypropylene (pp) and then the produced composites evaluated compared to those from net polypropylene. on the basis of obtained results from normalization equations in different treatments done, two treatments has been...

Abstract The Sound absorbent textile materials, especially nonwoven composite structure of reclaimed materials which have low manufacturing costs, relative density and are more attractive. In this research the use cotton polyester fiber for production sound absorption has been investigated. Three different blend ratios fibers that is 25:75, 40:60 50:50 used. composites specified their physical ...

Abstract Recycled steel fiber comes from the waste produced by machining. Adding recycled into concrete can significantly enhance toughness of concrete. In order to study impact fiber-reinforced concrete, drop weight repeated experiment method was used performance under load. Four kinds samples with different volume contents were designed and made, loading experiments five working conditions ca...

The final attenuation and twisting of fiber take place at ring spinning machine hence its optimized performance is very crucial in terms yarn quality. Drafting has a decisive effect on There exist many influencing parameters the geometry that have to be for manufacturing quality yarn. present research work was carried out develop Artificial neural networks (ANN) based prediction model polyester...

Cellulose aerogels with polyester resin as cross-linkers have attracted much attention. This study describes the route to produce a fully bio-based aerogel high added value from waste paper and starch, cellulose acetate starch–cellulose mixture for oil adsorption, instead of environmentally harmful resin. The manufacturing process is simple, sustainable cost-efficient, without releasing by-prod...

In this study, an industrial source) E-Glass fiber) and a natural source (chestnut filler) were combined to improve the properties of polyesters. Hand-layup technique was applied in work. Polyester (UPE) reinforced with E-glass fibers, then nano chestnut particles. All composites prepared (10% wt.) for all sheet ratio Nano composite preparing hybrid composites, particles used reinforce E-glass/...
