Fibers, yarns, woven fabric including the yarns and fibers, and methods of manufacturing the same are disclosed. Fibers can include base material staple fibers and dissolvable or water-soluble fibers that are mixed together to define an ultra-homogenous yarn comprising base material and dissolvable material, which is provided in at least the warp direction to form a woven fabric having a 7-end, 8-end or 10-end sateen weave. A processing step provides for the removal of the dissolvable fibers to produce a yarn defining a plurality of pores that are uniformly distributed throughout the structure of the yarn. The woven fabric has a thread count between 450-1200. The woven fabric is thermally-insulative, breathable and moisture-wicking.

The present invention provides a method for successively introducing water soluble fibers into finish fibers (e.g. cotton) to produce a hollow and ultra soft structure, by introducing water soluble slivers into the center of a multi-hole feeder with multiple cotton fiber slivers arranged around the water soluble fiber in a pre-drawing process via a multi-hole sliver feeder. A plurality of these fibers can be drawn together to produces a fiber having multiple water soluble fibers. A cloth, e.g., towel, can be made using the method.

Provided are a graphene-based fiber in which a liquid-crystalline aromatic compound is intercalated into a graphene-based material, a graphene-based carbon fiber obtained by carbonizing the graphene-based fiber, and a method of manufacturing the same.

High-melting antimicrobial polymer fibers and antimicrobial fabrics comprising such fibers are prepared by preparing a masterbatch of polymer pellets (e.g., PET), silver and copper salts, and a compounding agent which provides free flowing polymer pellets which can be prepared in advance, with a long shelf life. Polymer masterbatches prepared by the methods of the invention can produce limited color or off-white antimicrobial fibers and fabrics using conventional melt spinning manufacturing methods. Fabrics incorporating fibers of the present invention are potent inhibitors of Athlete's foot fungi, gram negative and gram positive bacteria, and drug resistant pathogens.

The present disclosure relates to the field of textiles, and in particular, to a multifunctional temperature-adaptable yarn, and a preparation method and use thereof. A multifunctional temperature-adaptable yarn is prepared from 20-30% of a temperature-adaptable fiber, 20-30% of an antibacterial fiber, and 40-60% of a cotton fiber in mass percentage by blending. The cotton fiber is a short fiber having a length of 10-50 cm. The multifunctional temperature-adaptable yarn has a linear density of 18-45 tex, a single yarn breaking strength of 12.5-12.8 cN/tex, a single yarn breaking strength coefficient of variation (Cv) of 11.5-12.5%, and a coefficient of variation of mass (CVm) of 11.3-11.4%. The multifunctional temperature-adaptable yarn in the present disclosure is made by blending three types of fibers and thus enabled to have good antibacterial and temperature adaptation properties.
