Application of strong alkali penetrant resistant agent in textile industry

Mercerizing cotton and its blended fabrics with concentrated alkali has become a key process in dyeing and finishing. However, due to the large viscosity of the lye, weak penetration and short time, the lye is difficult to penetrate into the interior of the fiber in a short time, so that the mercerization is not sufficient, which will affect a series of dyeing and finishing processing.

In order to solve this problem, it is necessary to rely on the role of additives such as penetrants. As a mercerizing penetrant, it must be resistant to strong alkali and less polluting to the environment. Phosphate ester is a kind of high turbidity point, strong alkali resistance, high temperature resistance, non-toxic, low bubble, easy biodegradation of efficient penetrant, rapid development in recent years, in the front treatment of this kind of varieties more development, more widely used.

At present, the main products in this category on the market are: fatty alcohol or fatty alcohol polyoxyethylene ether phosphate, such as isooctanol phosphate, AEO-3P, AEO-9P, etc.; Alkyl phenol polyoxyethylene ether (TX\OP\NP) phosphate ester, such as NP-4P, NP-10P, etc., because it contains APEO, the application in textile is limited.

The use of phosphate surfactant will produce phosphorus containing wastewater, when the phosphorus content in the water is too high, it will promote the excessive proliferation of algae, destroy the balance of the original water, and cause eutrophication pollution.

It has excellent wetting and permeability, resistance to strong alkali, strong acid, high concentration electrolyte, no turbidity point, and can be used at high temperature. Does not contain benzene ring structure, does not contain APEO, does not contain phosphorus, will not cause pollution to the environment after degradation, is a new type of environmental protection penetrant.
