Problems solved by technology

However, the current application of chitin is limited to the use of pure chitin-chitosan to produce fiber manufacturing technology or the use of chitin-chitosan as a fabric finishing agent, and the use of chitin and cellulose blending There are few technologies to produce health-care fibers with good dyeability, biocompatibility, antibacterial and deodorant properties, and easy degradation, which greatly limits the utilization of chitin and hinders health care. type fiber development

Abstract

The invention discloses a production method of health fiber and a health fiber produced by the method. The method comprises the following steps of preparing a chitin adhesive and a cellulose adhesive respectively from chitin and cellulose, mixing to obtain a spinning solution, and producing the health fiber by the mixed spinning solution. The health fiber production method of the invention has low requirement for temperature and vacuum degree for alkalization, sulfonation, etc., and is convenient and suitable for industrial production. The health viscose fiber containing chitin as a portion thereof has a plurality of characteristics such as long bacterial resistance, good chromaticity, biocompatibility, bacterial resistance as well as deodorization, and easy degradation.

Description

technical field [0001] The invention relates to a man-made textile fiber, in particular to a production method of health-care viscose fiber and the health-care viscose fiber produced by the method. Background technique [0002] Cellulose fiber has a long history in man-made fibers and is widely used. Due to its wide source of raw materials, excellent hygroscopicity, air permeability, comfortable clothing, good dyeability and ecological relevance, it occupies an important position in the production and application of man-made fibers. stable position. But the textiles of this kind of fiber can't meet people's various requirements such as antibacterial property and biocompatibility. [0003] Modern microecological studies have shown that there is a certain amount of microbial flora on the surface of human skin. The normal flora on the surface of human skin includes three types: ① native flora (also known as resident flora), such as Propionibacterium acnes and other flora, The...
