Problems solved by technology

Foam brings a lot of trouble to textile processing, not only will it cause uneven dyeing and finishing, but also cause the loss of working fluid, resulting in economic losses
However, the stability of traditional defoamers is not good, and oil stains or oil spots may appear on the fabric, which will make the product downgrade or be called waste product

Abstract

A special organic silicon defoamer for the textile industry is prepared from raw materials in parts by weight as follows: 3-5 parts of petroleum sulfonic acid, 2-4 parts of hexamethylenetetramine, 5-17 parts of dialdehyde starch, 8-16 parts of polyvinyl acetate, 12-22 parts of white carbon black, 5-7 parts of polyether modified silicone, 3-5 parts of polyoxyethylene sorbitan fatty acid ester, 2-6 parts of thiodiglycol, 4-7 parts of thiourea dioxide, 5-8 parts of sodium hydrosulfite, 8-14 parts of a thickener, 4-7 parts of silicone oil with low hydrogen content, 2-5 parts of hydroxy-terminated polydimethylsiloxane, 4-7 parts of aluminum trioxide and 2-4 parts of sodium chloride. The special organic silicon defoamer for the textile industry has the benefits that the defoamer has the characteristics of fast defoaming, good foam inhibiting performance, stable chemical property as well as heat resistance.

Description

technical field [0001] The invention relates to a special organosilicon defoamer for the textile industry. Background technique [0002] Defoamers, also known as antifoaming agents, will produce many harmful foams in the process of industrial production, and defoamers need to be added. Among the 8 main processes of fabric processing (spinning, sizing, weaving, desizing, scouring, bleaching, dyeing (tie-dyeing) and finishing), there are 4 processes (sizing, scouring, dyeing and finishing). Finishing) requires the use of surfactants and other additives, so there are different degrees of foam troubles. Foam brings a lot of trouble to textile processing, not only will it cause uneven dyeing and finishing, but also cause the loss of working fluid, resulting in economic losses. However, the stability of traditional defoamers is not good, and oil stains or oil spots may appear on the fabric, making the product downgrade or called waste.
