A cotton fiber particulate and method of manufacture including, generally, obtaining cotton fibers; mixing the cotton fibers with a solvent such as water to obtain a fiber furnish; milling the fiber furnish; and drying the fiber furnish to recover the cotton fiber particulate. Other steps include modifying the pH of the fiber furnish with a material such as calcium carbonate in an effort to make the fibers brittle, and filtering the fiber furnish to recover the cotton particulate. The fibers are milled to between 5-25 microns in length with a mean length of less than 50 microns with a mean length of 20 microns preferred.

A nanofiber spinning method and device for producing a high strength and uniform yarn made of nanofibers. The device includes: a nanofiber producing unit (2) which produces nanofibers (11) by extruding polymer solution, prepared by dissolving polymeric substances in a solvent, through small holes (7) and charging the polymer solution, and by allowing the polymer solution to be stretched by an electrostatic explosion, and which allows the nanofibers to travel in a single direction; a collecting electrode unit (3) to which an electric potential different from that of the charged polymer solution is applied, and which attracts the produced nanofibers (11) while simultaneously rotating and twisting the nanofibers, and gathers them for forming a yarn (20) made of the nanofibers (11); and a collecting unit (5) which collects the yarn (20) passed through the center of the collecting electrode unit (3).

Wash-durable fluorochemical-containing textile and / or fiber treatments that simultaneously impart soil resistance (or soil-release) properties and moisture wicking characteristics to target fabric substrates are provided. Such treatments surprisingly impart these two simultaneous effects to target fabrics and / or fibers because fluorochemicals generally provide moisture repellency rather than moisture wicking capabilities. As prior soil release / moisture wicking treatments do not function properly, or, alternatively, compromise hand or other properties of certain target textiles after treatment application, a new, effective, soil release / moisture wicking formulation for such purposes was needed. The inventive treatment is extremely durable on such fabric substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its soil release / moisture wicking properties. The method of adherence to the target yarn, fiber, and / or fabric may be performed any number of ways, most preferably through the utilization of a jet dyeing system or through a steam-transfer method. The particular methods of adherence, as well as the treated textile fabrics and individual fibers are also encompassed within this invention.

A microfiber substrate of improved carding ability and its manufacturing method, and more particularly a micro-fiber spun by conjugated melting of crystallization difference of high crystallization polymer and low crystallization polyester, drawn to form an unsplit microfiber staple having a layer of thin film in its surrounding, the microfiber staple which is still kept in unsplitting state during opening, carding and lapping treatment, will be split just at the layer of thin layer of its surrounding of the microfiber staple by spunlace to completely split from the microfiber, knitted to form water-jet punch web, then subject to hot water to shrink to densification. The microfiber nonwoven web excellent in the wiping effect, cleaning effect and microfiber artificial leather excellent in the hand feeling and fluff compaction without environment pollution is enabled to offer the artificial leather more cheaply and easily finished.

Isolated composites are disclosed comprising collagen fibers isolated from a Sarcophyton sp. coral. An exemplary composite comprises as a first component a bundle of collagen fibers, the collagen fibers being isolated from a Sarcophyton sp. coral, and a second component selected from the group consisting of a polysaccharide, a polypeptide, polylipid, a synthetic polymer, a metal and a mineral, wherein the bundle of collagen fibers comprise woven fibers, twisted fibers, braided fibers, knitted fibers, tied fibers, or sutured fibers. Uses thereof and method of generating are also disclosed.
