Disclosed are textile fibers, yarns, and fabrics having improved comfort and water and odor adsorption properties, and methods of manufacturing same. The improved textiles have an increased distribution of adsorbing particles distributed at the surface of the fibers and yarns to enable greater overall surface area for adsorbance.

Techniques are described for controlling widths of nanofiber sheets drawn from a nanofiber forest. Nanofiber sheet width can be controlled by dividing or sectioning the nanofiber sheet in its as-drawn state into sub-sheets as the sheet is being drawn. A width of a sub-sheet can be controlled or selected so as to contain regions of uniform nanofiber density within a sub-sheet (thereby improving nanofiber yarn consistency) or to isolate an inhomogeneity (whether a discontinuity is the sheet (e.g., a tear) or a variation in density) within a sub-sheet. Techniques for dividing a nanofiber sheet into sub-sheets includes mechanical, corona, and electrical arc techniques.

A method of manufacturing multi-ply separable textured yarn, the method comprising, passing a multi-ply separable interlaced filament yarn through a texturizing unit to form a multi-ply separable draw textured yarn, wherein the multi-ply separable interlaced filament yarn is separable in to at least two separable interlaced filament yarn, wherein the interlacing of the filaments within each separable interlaced filament yarn is retained during further processing of the yarn to fabric and in the fabric.

A preparation method of PVA fiber comprises the following steps: preparing a spinning dope; PVAc is used as a raw material, and dissolved with addition of methanol before filtration, and then the spinning dope is obtained; spinning; the spinning dope is injected into a spinneret, and the ejected fibers are brought into a direct current electrolytic cell, and undergo a series of reactions of alcoholysis, electrolytic catalytic alcoholysis, and the levering of the alcohol; and the solution formulation in the electrolytic coagulation bath comprises alkali, alcohol and water; acid bath; through stretching, drying, washing with water, crimping with hot water and packaging, a finished polyvinyl alcohol fiber product is formed. The mirabilite is not needed in the coagulation bath, and PVA is obtained by the alcoholysis of PVAc in an electrolytic cell, and the produced PVA fibers present high purity and few impurities.
