A nonwoven member that includes a plurality of piezoelectric fibers. The nonwoven member is formed into a cloth by intertwining the plurality of piezoelectric fibers. The nonwoven member inhibits the growth of bacteria due to an electric charge generated when an external force is applied to the piezoelectric fibers.

The invention relates to a process for manufacturing a multilayer knitted textile by heating a multi-layer knitted textile in the presence of one or more dye compounds, wherein the multilayer knitted textile comprises a fabric outer layer and a fabric inner layer, wherein the fabric outer layer is knit from a first yarn containing a combination of modacrylic fibers and cotton fibers, wherein the fabric inner layer is knit from a second yarn made from 50-90% HBA/HNA filaments, wherein the heating shrinks the outer layer from about 5 to 25% in length, width, or both.

Sliver containing cellulose acetate staple fibres is obtained that exhibits good fibre to fibre cohesion energy and can be successfully drawn and made into spun yarns. Such slivers can be made of cellulose acetate staple fibres that have of round shape, a denier of less than 3.0, a crimp frequency per inch (CPI) from 5 to 30, a good fibre to fibre coefficient of friction and have a low static charge. The textile fabrics made from spun yarns have plant-based renewable resources by containing the cellulose acetate staple fibres, and can exhibit a thermoplastic behaviour to impart better dimensional stability to a textile fabric. The low denier of the cellulose acetate fibres can impart a feel similar to that of cotton, yet can be successfully processed through carding machines to form cohesive slivers and retain their integrity throughout the drawing process, allowing them to be formed into spun yarns.

A yarn comprising a plurality of bicomponent filaments having a first region comprising a first polymer composition and a second region comprising a second polymer composition; the regions being distinct and present in the bicomponent filaments in a sheath-core structure or a side-by-side structure; wherein the first polymer composition comprises aramid polymer containing 0.5 to 20 weight percent homogeneously dispersed discrete carbon particles and the second polymer composition comprises aramid polymer being free of discrete carbon particles and having at least one homogeneously dispersed masking pigment, the yarn having a total content of 0.5 to 5 weight percent discrete carbon particles.

A production process of mixed yarns and mixed yarns obtained from circular and or sustainable and or biodegradable textiles within any textile industry and or adapted in the machines within spinning mills. This makes possible a very large combination of different types of textile yarn mixtures and a wide range of weights of mixed sustainable and or biodegradable yarns, to meet and create new demands for sustainable and circular textile products. The process described for injection of compressed air is the combination and mixing of sustainable and circular and or biodegradable continuous filament yarns with biodegradable, and sustainable natural and/or artificial spun yarns, bringing technology to the products in line with the sustainability of the environment. This makes possible a definitive solution in ocean contamination by synthetic fibers and prevents much of the artificial textile fibers from fabrics and clothes, which release their cut fibers during industrial and domestic washing.
