Problems solved by technology

However, the moisture and splashing of water droplets generated in the dyeing and finishing process of the printing and dyeing processing factory are completely unpredictable to the processor. Once the moisture content in the air is sufficient, the heat generated by the powdered sodium dithionite will reach or exceed the autoignition temperature.
[0007] And Publication No.: Although the solid particle stabilization system described in U.S. Patent Document 4066390 can obtain good cleaning effect after disperse dyeing, it still belongs to solid state, and it is very inconvenient to use and operate; secondly, when the solid is mixed, the environment and processing conditions will cause its poor stability
Furthermore, solid particles are prone to dust, causing the operator to inhale and cause respiratory occupational diseases
[0008] It can be seen from the above that the current reduction cleaning system of polyester still has many fatal flaws.

Abstract

The invention discloses a reduction cleaning agent for terylene. The reduction cleaning agent for the terylene is characterized by comprising deionized water, an unsaturated reduction system, a surfactant system and a pH value buffering system, in parts by mass: 84 to 35 parts of the deionized water, 10 to 50 parts of the unsaturated reduction system, 5 to 10 parts of the surfactant system and 1 to 5 parts of the pH value buffering system. The reduction cleaning agent for the terylene is stable in state, avoids heating and spontaneous combustion conditions, does not have pungent smell, is convenient to transport and store, and has an excellent cleaning effect.

Description

technical field [0001] The invention relates to the field of fabric dyeing and finishing auxiliaries, in particular to a polyester reduction cleaning agent which replaces sodium hydrosulfite and has good cleaning effect and a preparation method thereof. Background technique [0002] Polyester is a kind of synthetic fiber. Because of its excellent setting performance and its excellent deformation resistance after repeated washing, polyester is widely used in clothing, textile and other industries. And along with the continuous development of fabric blending technology, polyester-cotton blended fabrics are more and more favored by garment manufacturers. Although polyester has excellent setting performance, it has a major technical defect in dyeing and finishing. Traditional polyester is mostly dyed with disperse dyes, and disperse dyes are non-polar small molecules with extremely poor hydrophilic properties. Therefore, it is impossible to use conventional washing methods to r...
