Problems solved by technology

[0005] The technical problem to be solved by the present invention: in view of the fact that ordinary yarns do not have the function of moisture absorption and heat generation, the garment fabrics produced do not have good hygroscopicity, cannot absorb the sweat emitted by the human body, cannot generate heat, and are easy to breed bacteria. Without the defects of warming effect and antibacterial effect of the fabric, a preparation method of moisture-absorbing, heat-generating and anti-bacterial yarn is provided

example 1

[0023] According to the mass ratio of 1:2, polyacrylonitrile and 15% sodium hydroxide solution were mixed in a beaker, hydrolyzed at a temperature of 85°C for 12 minutes, cooled and discharged to obtain a reaction solution, and then added to the reaction solution Add soybean protein with 7% of the mass of the reaction solution to the mixture, continue stirring and reacting for 35 minutes, and discharge to obtain a modified polyacrylonitrile hydrolyzate; weigh 20 g of crab shells and grind them for 10 minutes to obtain crab shell powder, and then add crab shell powder to the crab shell powder Yogurt with 0.5% shell powder mass is put into a fermenter, sealed and fermented at a temperature of 35°C for 6 days. The fermentation product of chitosan and the sodium hydroxide solution that mass fraction is 30% are mixed to be placed in the beaker, be frozen under the condition of-12 ℃ for 35min, obtain frozen liquid, finally freeze liquid and 2-chloroethanol by mass The ratio was 2:1 ...

Abstract

The invention discloses a method for preparing moisture-absorbing, heat-generating and anti-bacteria yarn, which belongs to the technical field of yarn preparation. Firstly, polyacrylonitrile is modified by alkaline solution and soybean protein. The alkaline solution contains a large number of hydroxyl groups, so that water vapor molecules are adsorbed on the surface of the substrate, thereby improving the moisture absorption and heat generation performance of the yarn. In addition, these hydrophilic groups can make The polar force between polyacrylonitrile molecules is weakened, which is conducive to the improvement of the moisture absorption and heat generation performance of the yarn; the present invention utilizes the chitin in the crab shell to prepare chitosan through a fermentation method, thereby improving the solubility of chitosan, and in addition Adding chitosan in the matrix is ​​beneficial to improve the antibacterial properties of the yarn. In addition, the self-made chitosan is further modified with silver nitrate solution, and the generated hydroxyl radicals and active oxygen ions can destroy bacterial proliferation and achieve antibacterial. After the bacterial cell loses its activity, the silver ions are freed from the bacterial cell to achieve long-lasting antibacterial, thereby improving the antibacterial property of the yarn, and has a wide application prospect.

Description

technical field [0001] The invention discloses a method for preparing moisture-absorbing, heat-generating and anti-bacteria yarn, which belongs to the technical field of yarn preparation. Background technique [0002] Yarn refers to a product processed from various textile fibers into a certain fineness, which is used for weaving, rope making, thread making, knitting and embroidery, etc. Yarn is divided into: short fiber yarn, which is processed from short fiber through spinning, divided into ring spinning, open end spinning, self-twisting yarn, etc. Continuous filaments, such as natural silk and chemical fiber filaments, are divided into twisted or untwisted, smooth filaments or textured filaments, etc. Combined staple fiber and continuous filament yarn, such as polyester-cotton filament core-spun yarn, etc. The thread is made of two or more single yarns combined and twisted. Classified by yarn raw materials: pure spun yarn, pure spun yarn is a yarn spun from a fiber mat...
