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 acidmetal 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 yarns. 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 in dry and wet conditions, stable size, small shrinkage rate, straight, not easy to wrinkle, easy to wash, fast dry characteristics. However, the polyester fiber in the 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 the wearing process. It is difficult to wash, and it cannot be ironed at high temperature and soaked in boiling water. [0003] After searching the prior art, the patent with the application number of 201310364324.9 (published on December 11, 2013) discloses a pretreatment proce...
