Abstract

The invention provides a low-temperature bleaching process of a bamboo fiber yarn. The low-temperature bleaching process comprises the following treatment processes: putting the bamboo fiber yarn into a low-temperature scouring and bleaching liquid, of which the bath ratio is (1:5) to (1:10); carrying out heat preservation at 60-80 DEG C for 40-60 minutes, and washing, wherein the low-temperature scouring and bleaching liquid is prepared from sodium percarbonate, imidazole metal complex and tea saponin. According to the method provided by the invention, the bamboo fiber yarn can be bleached at relatively low temperature; an energy source is saved; and the damage degree of the bamboo fiber yarn can be reduced.

Description

technical field [0001] The invention relates to the field of low-temperature pretreatment of textiles, in particular to a low-temperature bleaching process for bamboo fiber yarn. Background technique [0002] Bamboo fiber is another new type of fiber that has been successfully developed and put into production in my country after soybean fiber. Due to the porous cross-section of bamboo fiber, it has excellent capillary effect, can quickly absorb or discharge water, and has good hygroscopicity, air permeability, and durability. Abrasiveness and dyeing properties, knitted fabrics made of bamboo fiber yarns feel soft, smooth, and good drapability; bamboo fibers have natural antibacterial properties and strong deodorizing properties, and are especially suitable for making underwear. [0003] As a new type of fiber, bamboo fiber has poor whiteness and yellow fiber surface due to the existence of natural pigments. In addition, bamboo fiber has poor alkali and oxidant resistance, so...
