Abstract

The invention discloses a knitted fabric pretreatment cold-pad-batch assistant, which relates to the technical field of knitted fabric treatment assistants. The knitted fabric pretreatment cold-pad-batch assistant comprises the following components of peroxide salt, a stabilizer, a strong-base release control agent, a water treatment agent, an activator and a non-ionic surface active agent. The invention also relates to a preparation method of the knitted fabric pretreatment cold-pad-batch assistant. By virtue of the preparation method, the problems of high safety risk, unstability of products, high consumption during production and low selectivity of processed products in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of processing auxiliary agents for knitted fabrics, in particular to a cold storage auxiliary agent for pretreatment of knitted fabrics, and also relates to a preparation method of the auxiliary agent. Background technique [0002] The current pre-treatment cold pile additives for knitted fabrics are mainly based on strong alkali, high alkali content, strong oxidation and high oxidation content. Due to the strong action force, it is easy to produce many uneven states and cause great damage to the fibers. It is the biggest defect of traditional additives and the bottleneck that cannot be broken through. For example, during the static stacking process, there will be a difference in whiteness, a difference in whiteness inside and outside, and alkali spots due to the movement of alkali. [0003] Strong alkalinity and strong oxidizing properties have the following disadvantages: [0004] (1) It brings great saf...
