Abstract

The invention relates to a preparation method of far infrared chitosan fiber. The preparation method comprises the following steps: axially stretching a chitosan fiber product in a swelling agent in which far infrared ceramic powder is dispersed, washing, and drying to obtain the far infrared chitosan fiber, wherein the chitosan fiber product is chitosan fiber obtained through wet spinning. Compared with the chitosan fiber product, the prepared far infrared chitosan fiber has the advantages that the orientation degree is increased by 30.3 to 41.5%, the crystallinity is increased by 12.6 to 21.9%, the breaking strength is increased by 25.3 to 32.8%, the infrared emissivity is increased by 42 to 56%, and the thermal insulation performance is increased by 30.5% to 42.9%, and under the radiation of infrared rays, the apparent temperature is increased by 2 to 5 DEG C. The preparation method is simple, low in cost and low in energy consumption; the orientation of chitosan molecules is effectively improved; the tensile property is enhanced; the far infrared ceramic powder and the chitosan fiber can be combined more firmly, so as to make the far infrared performance of the chitosan fiber stable.

Description

technical field [0001] The invention belongs to the field of fiber reinforcement, and relates to a preparation method of far-red shell polysan fiber. Background technique [0002] The biological activity and safety of chitosan are more and more recognized by people, and its application is more and more extensive. Chitosan fiber naturally has five major functions: non-toxic, anti-mildew, anti-bacterial, flame-retardant, and anti-static. Used in the production of bedding, underwear, socks and towels and other products that are in direct contact with the skin. In the early 1990s, Japan was the first to use the properties of chitosan fiber to make antibacterial and deodorant underwear and pantyhose blended with cotton, which were favored by consumers. From 1999 to 2000, Donghua University developed chitin series blended yarns and fabrics and made them into various health underwear, pantyhose and baby products.
