Abstract

The invention discloses dyeing enzyme for improving pilling resistance of a polyester-cotton knitted fabric, and belongs to the technical field of textile dyeing. The dyeing enzyme comprises, by weight, 5-15 parts of heat-resistant weak-acidic pectinase, 5-15 parts of cutinase, 5-25 parts of wide pH (potential of hydrogen) cellulose, 1-5 parts of C21 monocyclic binary acid salt, 10-30 parts of biomass polyoxy alkyl ether, 1-5 parts of N-alkyl phthalimide and 40-70 parts of water. According to the dyeing enzyme for improving pilling resistance of the polyester-cotton knitted fabric, refining and oil removing, polishing and polyester dyeing can be completed once, energy, water and time are saved, emission is reduced, energy conservation and emission reduction requirements of green printing and dyeing are met, COD (chemical oxygen demand) content of waste water can be reduced, and a product and a printing and dyeing process are innovated.

Description

technical field [0001] The invention relates to a refining and dyeing enzyme for improving the anti-pilling performance of polyester-cotton knitted fabrics and a preparation method, belonging to the technical field of textile dyeing. Background technique [0002] Among all kinds of textiles, polyester-cotton blended fabric has become the most important kind of blended fabric, and polyester-cotton blended fabric needs to take into account two kinds of fibers with different properties during dyeing and finishing. The traditional medium-dark color processing technology is refining and degreasing→polyester dyeing→reduction cleaning→polished cotton dyeing→soaping, etc. The process is lengthy and time-consuming; the additives used have poor biodegradability, and the COD of the wastewater is high; the alkali remaining inside the fiber after reduction cleaning is likely to cause pH fluctuations in the polishing and dyeing process, affecting the polishing effect. Therefore, the trad...
