Pre-treatment Auxiliaries

The pre-treatment Auxiliaries at home and abroad are mainly composed of anionic surfactants and nonionic surfactants, or mixtures with other inorganic and organic substances. This can not only improve the ability of wetting, penetrating, dispersing, solubilizing, and decontamination, but also make up for the shortcomings of nonionic surfactants and anionic surfactants. It should be compounded according to the requirements of various factories, such as alkali resistance, penetration, whiteness, and hair efficiency.

Printing and dyeing pretreatment Auxiliaries mainly include scouring agents, detergents, oxygen bleaching stabilizers, and chelating dispersants. Their functions are respectively impurity removal, decontamination, bleaching, anti-embrittlement and anti-cavitation.
