Abstract

The invention relates to a composite fiber as well as a preparation method and an application thereof. The composite fiber comprises a skin layer and a core layer, wherein the core layer is polyvinyl alcohol; the skin layer is prepared from components in parts by mass as follows: 30-75 parts of carboxyethyl chitosan fiber, 10-20 parts of alginic acid fiber, 1-5 parts of a lonicera japonica extract, 3-8 parts of shellac pigment and 2-7 parts of gardenia yellow pigment. The skin-core structure is adopted, the lonicera japonica extract, the shellac pigment and the gardenia yellow pigment are added, and the alginic acid fiber is composited into carboxyethyl chitosan fiber, so that the prepared composite fiber has excellent mechanical performance and antibacterial performance and has the sterilizing rate up to 99.9% for staphylococcus aureus.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a composite fiber and its preparation method and application. Background technique [0002] Chitin is a renewable resource second only to cellulose in reserves on the earth. Its deacetylated derivative, chitosan, has good biocompatibility, biodegradability, hemostasis, and promotion of wound healing. Absorbable surgical sutures, wound dressings, drug carrier materials, artificial skin and other tissue engineering scaffold materials have broad application prospects. [0003] Dissolve chitosan in organic acid or inorganic acid to form viscous colloid. After spinning, coagulation, washing, drying and other processes, chitosan fiber can be obtained, which can be used to prepare wound dressings. Japanese Open Patent Gazette (JP 60,059,123, 1985), Chinese Patent Publication No. CN1129748A, the publication date is August 28, 1996, the title of the invention is "deacetylated chitin fib...
