Pretreatment auxiliaries for cotton

In the process of pr-treatment of cotton mainly using scouring agent, alkali resistant penetrating agent, hydrogen peroxide stabilizer and hydrogen peroxide remover. Before dyeing and printing, cotton fabric needs a certain process to remove the impurities and oil from the cloth surface. This processing is usually called scouring, and the function of the scouring agent is penetrating, emulsifying, washing, dispersing and wetting. The penetrating agent of cotton not only needs good permeability, but also needs good alkali resistance. The role of hydrogen peroxide stabilizer is to control the decomposition rate and pH value of hydrogen peroxide in the process of oxygen bleaching or desizing, boiling and bleaching, so as to avoid fiber damage and achieve good bleaching effect. The residue hydrogen peroxide will affect the color and dyeing reproducibility, hydrogen peroxide removal agent decomposite and remove residual H2O2, to ensure the smooth progress of dyeing.
In the process of pr-treatment of cotton, scouring agent exerts the effect of scouring and penetrating. When using hydrogen peroxide bleach cotton fabric, hydrogen peroxide stabilizer and hydrogen peroxide remover can ensure the smooth processing of bleaching and subsequent dyeing.
