Problems solved by technology

However, due to issues such as the manufacture, price, and source of activators, the use of these activators only solves the difficulty of low-temperature bleaching with hydrogen peroxide, but does not solve the difficulty of low-temperature scouring and bleaching, nor can it simultaneously realize cotton or cotton blended knitted fabrics or cotton loose fibers. The pre-treatment process of scouring and bleaching in a low-temperature bath, the pre-treatment process of scouring and bleaching in a low-temperature bath of cotton or cotton blended yarn, and the cold pad-batch process of cotton fabrics

Abstract

The invention discloses one dosage type low temperature scouring and bleaching agent which comprises a surface active agent, a hydrogen peroxide activator, a bleaching synergist, a chelating agent, a hydrogen peroxide stabilizer, a defoamer and a filler in a mixing mode. The one dosage type low temperature scouring and bleaching agent can be used for scouring and bleaching cotton, cotton blend knitted fabric or cotton loose fiber in a low temperature bath of 60 DEG C- 85 DEG C and cotton or cotton mixed and blended yarns in a low temperature bath of 80 DEG C -95 DEG C and for cold pad-batch processing of cotton fabric. The one dosage type agent is a solid product which is convenient to pack and transport. One agent can replace more than three agents such as alternative scouring agent, hydrogen peroxide activator, chelating agent, brightening agent and oxygen bleaching stabilizer during processing, which is convenient to feed and process. The one dosage type low temperature scouring and bleaching agent is widely applicable to processes such as scouring and bleaching in bath and cold pad-batch processing.

Description

Technical field [0001] The present invention relates to the technical field of textile printing and dyeing pretreatment, in particular to a one-part low-temperature scouring and bleaching auxiliary agent and its use. The one-part low-temperature scouring and bleaching auxiliary agent is suitable for the pretreatment of cellulose fiber non-finished textiles. Background technique [0002] At present, energy conservation and emission reduction have become a global consensus, and the dyeing and finishing industry also focuses on reducing energy consumption, reducing processing costs, shortening the processing cycle, and improving the quality of finished products to enhance competitiveness. [0003] As we all know, the pretreatment of cotton or cotton blended fabric is the processing process that consumes the most energy and water and discharges the most pollution in the dyeing and finishing process, and is also the key to the quality of the finished dyeing and finishing product. At pre...
