Abstract

The invention discloses an antibacterial cotton textile fiber preparation method, which is characterized by comprising: immersing 5 g of a fabric in a caustic soda solution with a mass fraction of 5-30% for 15-60 min at a temperature of 20-35 DEG C, taking out the fabric, placing into 100 g of a chloroacetic acid aqueous solution with a mass concentration of 10%, taking out after 30-45 min, sealing the fabric in a polyethylene plastic bag, placing in a 30-80 DEG C oven, carrying out a reaction for 1-3 h, washing 3-5 times with 50 ml of an ethanol and water mixing solution with a volume ratio of 80:20, drying, dispersing 0.6 g of sodium alginate, 0.7 g of chitosan and 2.2 g of a coptis chinensis extract in 10 g of distilled water, carrying out mixing stirring for 15 min at a temperature of 30 DEG C to obtain the chitosan solution of microcapsule, immersing the modified cotton textile fiber in the chitosan solution of the microcapsule for 30-45 min, taking out, immersing 6 g of a modified starch cross-linking agent, carrying out a reaction for 0.5-1.5 h, adding 0.3 g of a material C, carrying out a reaction for 1 h at a temperature of 90 DEG C, drying for 5-15 min at a temperature of 150 DEG C, carrying out water washing 3-5 times, and drying so as to obtain the antibacterial textile. The prepared textile of the present invention has the lasting antibacterial effect.

Description

technical field [0001] The invention relates to a preparation method for enhancing textile antibacterial properties, in particular to a preparation method for antibacterial cotton textile fibers. Background technique [0002] Coptis chinensis is the dry rhizome of Coptis chinensis, Coptis triangularis or Yunlian, also known as Chuanlian and chicken feet. This taste is bitter, cold in nature, the heart, stomach, liver, and large intestine meridians, and has the effects of clearing away heat, purging fire, drying dampness, and detoxifying. Clinically, it is mostly used to treat dysentery, acute gastroenteritis, chronic diarrhea, respiratory infection and various inflammations. In recent years, studies have found that it also has obvious effects in anti-tumor, anti-arrhythmia, and hypoglycemia. [0003] The main components are alkaloids and lignans, in addition to phenolic acids, volatile oils, flavonoids, coumarins, terpenes, steroids, polysaccharides, etc. The alkaloids fou...
