Abstract

The invention provides a low temperature bleaching process of cotton-polyester blended yarns. The treatment process is as follows: putting cotton-polyester blended yarns into low temperature scouring and bleaching liquid, wherein the bath ratio is 1:5 to 1:10; maintaining the temperature at 60-80 DEG C for 40-60 minutes and washing. A low temperature scouring and bleaching agent is prepared from sodium borate, an oxalic acid metal complex and a scouring agent. The method provided the invention can be used for bleaching the cotton-polyester blended yarns at lower temperature, thereby saving energy and reducing the damage degree of the cotton-polyester blended yarns.

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 polyester-cotton blended yarn. Background technique [0002] Polyester-cotton blended fabric not only highlights the style of polyester but also has the advantages of cotton fabric. It has good elasticity and wear resistance under dry and wet conditions, stable size, small shrinkage, and is tall and straight, not easy to wrinkle, easy to wash, and fast. Dry features. However, the polyester fiber in polyester cotton is a hydrophobic fiber, which has a strong affinity for oil stains, and it is easy to generate static electricity and absorb dust during wearing, making it difficult to wash, and it cannot be ironed at high temperature or soaked in boiling water. [0003] After searching the prior art, the patent application number 201310364324.9 (publication date: December 11, 2013) discloses a pretreatment process for co...
