Low-foam scouring agent for cotton woven fabric continuous pad dyeing and preparation method of low-foam scouring agent

Abstract

The invention discloses a low-foam scouring agent for a cotton woven fabric continuous pad dyeing and a preparation method of the low-foam scouring agent, and the low-foam scouring agent comprises the following components in percentage by weight: 8.0%-16.0% of isomeric fatty alcohol polyoxyethylene ether, 4.0%-8.0% of block polyether L64, 12.0%-16.0% of sodium isopropyl benzene sulfonate, 10.0%-20.0% of fatty alcohol polyoxyethylene ether sodium phosphate, 2.0%-5.0% of sodium gluconate and 35.0%-64.0% of water. According to the low-foam scouring agent for the cotton woven fabric continuous pad dyeing and the preparation method of the low-foam scouring agent, the low-foam scouring agent has the advantages of being good in wetting and foam inhibition effect, high in emulsifying capacity, good in impurity and oil removal effect, easy to biodegrade and the like, and meanwhile the low-foam scouring agent has good compatibility with other surfactants and auxiliaries.

Description

technical field [0001] The invention relates to the technical field of textile auxiliaries, in particular to a low-foaming scouring agent for long-vehicle cotton woven fabrics and a preparation method thereof. Background technique [0002] The pre-treatment and scouring process is a complex chemical and physical-chemical process of textiles at a certain temperature with alkali and scouring aids, which includes penetration, cleaning, puffing, emulsification, saponification, dispersion, chelation and decolorization, etc., among which Penetration and cleaning are relatively important functions. The first step in the scouring process is that under the action of surfactants, the training liquid and chemicals penetrate into the fiber to make the fibers and impurities expand; the second step is the cleaning effect, that is, the fibers undergo After sufficient wetting, its natural impurities are removed by heat and chemical soaping, emulsification, extraction, dispersion, etc. The ...

AI Technical Summary

Problems solved by technology

During this process, a large amount of foam will make the operator unable to see the actual liquid level of the treatment liquid, which will cause the scouring agent to overflow, the chemical material will be uneven, and a large amount of foam will remain when the material is finally discharged, making the discharge dirty.

Excessive foam will float the fabric and block the nozzle of the working fluid circulation, which will aggravate the accumulation of dirt in the working fluid and contaminate the surface of the fabric or equipment. After hydrogen peroxide and caustic soda are added to the working fluid, the foaming of the surfactant will be aggravated. more severe blistering

In order to ensure the rinsing effect, a large amount of water will be required for multiple cleanings, excessively wasting water resources, and at the same time, a large amount of alkaline waste liquid will be produced, which will pollute the environment
