Disclosed is a method for producing an antimicrobial heat-retaining fiber. The method includes spinning a spinning solution onto a fiber-forming resin. The spinning solution includes 1.0 to 6.0% by weight of carbon particles and 0.2 to 2.0% by weight of a metal alkoxide coupling agent. The spinning solution further includes 0.5 to 3.0% by weight of inorganic particles composed of a metal powder, a ceramic powder, or a mixture thereof By using the metal alkoxide coupling agent, the carbon particles and the inorganic particles are dispersed in a resin. Also disclosed is a fiber produced by the method. The fiber is prevented from breakage during spinning and is imparted with heat-retaining and antimicrobial functions due to the presence of the carbon particles and the inorganic particles. Further disclosed is a fabric manufactured using the fiber. The fabric can be prevented from deterioration of wash fastness.

Antimicrobial cellulose fibers and antimicrobial cellulose fabrics are provided herein. Such an antimicrobial fiber can include a reactive antimicrobial compound comprising an antimicrobial agent that reacted with at least one reactive compound, and wherein the reactive antimicrobial compound is chemically fixed to a cellulose fiber.

Antimicrobial cellulose fiber and fabric comprising multiple antimicrobial cellulose fibers

A method for producing an antimicrobial cellulose fiber. The method includes reacting a reactive compound with an antimicrobial agent to prepare a reactive antimicrobial compound, chemically fixing the reactive antimicrobial compound to a cellulose fiber through chemical bonding between the reactive compound and the cellulose fiber, and stabilizing the cellulose fiber structure. Further disclosed is an antimicrobial cellulose fiber produced by the method. The antimicrobial cellulose fiber is a human friendly material that has excellent antimicrobial activity and deodorizing performance. The antimicrobial cellulose fiber can be manufactured in the form of raw cotton, sliver, roving yarn, spun yarn, woven fabric, knitted fabric, non-woven fabric, etc. The antimicrobial cellulose fiber may be blended with other fibers, such as natural fibers and synthetic fibers.

The object of this invention is to provide a temperature-sensitive state-changing hydrogel composition and a method of producing the same. The hydrogel composition includes 1-10 wt % of branched gelation polymer, 0.5 5 wt % of electrolyte gelation polymer, 0.5-5 wt % of skin-communication enhancer, 1-10 wt % of natural biomaterial, 3-30 wt % of polyhydric alcohol, 1-10 wt % of functional additive, and 30-93 wt % of water based on a total weight of the composition. Hydrogel is transformed into a fluid state at 10-50&#xb0; C. The hydrogel composition is transformed into a fluid state due to body temperature when it comes into contact with the skin to be fluidized, so that cosmetics or drugs contained in hydrogel are uniformly and quickly delivered into the skin.

Temperature sensitive state-changing hydrogel composition and method for their preparation

Disclosed is a chitosan microflake which is exceptionally improved in coatability to the skin. The chitosan microflake is manufactured by dissolving chitosan in a weak acidic, aqueous organic acid solution to give a chitosan solution, extracting chitosan from the solution, and solidifying the solution and pulverizing the form film into the microflake which has a width ten fold greater than thickness. With high coatability onto the skin, the chitosan microflake improves the medicinal efficacies of highly pure chitosan, including wound healing, sterilization, prevention or suppression of cicatrix formation, and recuperation from wounds, upon being applied to external traumas such as dermal damages, surgically operated regions and burns. In addition to the medicine and medical industries, the chitosan microflakes can find numerous applications in a broad spectrum of industries, including food, bioengineering, cosmetic, agricultural, chemical engineering, and environmental industries.
