Problems solved by technology

The traditional antibacterial finishing agents add mercury salts, lead salts, acid salts, etc., which are highly toxic and have a long residual period, and have been banned from use; while adding synthetic organic fungicides has a small amount and good effect, but there are short validity periods, The disadvantages of high toxicity and narrow application range limit its application

Abstract

The invention discloses a preparation method of an antibacterial silk. The antibacterial silk is prepared by the following raw materials by weight proportion: 70 to 85 percent of silk, 10 to 15 percent of titanium oxide concentrated liquor, 0.4 to 1.6 percent of silane coupling agent, 2 to 4 percent of hydroxypropyl methyl cellulose, 2 to 3 percent of polyethylene glycol, 0.2 to 1 percent of octamethyl cyclotetrasiloxane polymer, 3 to 4 percent of 2-methyl-4-isothiazoline-3-ketone, 0.4 to 1 percent of dispersing agent and defined amount of water. Various chemical reagents generate chain reaction with non-toxicity and environmental friendliness, the silk has soft texture and strong antibacterial ability, and the preparation method is simple and low in cost.

Description

technical field [0001] The invention relates to the field of silk preparation, in particular to a method for preparing antibacterial silk. Background technique [0002] Silk is a continuous "long fiber" formed by the solidification of the silk liquid secreted by cooked silkworms when they make cocoons. It is also called "natural silk" and is a natural fiber. Silk is the lightest, softest and thinnest natural fiber in nature. It can easily return to its original shape after the external force is removed. [0003] The natural protein structure in silk fabric makes it a textile material with a good affinity for the human body, but it also becomes the best place for bacteria to breed and multiply. Therefore, antibacterial finishing of silk fabrics has attracted people's attention. The traditional antibacterial finishing agents add mercury salts, lead salts, acid salts, etc., which are highly toxic and have a long residual period, and have been banned from use; while adding syn...
