What is fabric thickener
Depending on the method, 2113 blackening agents are usually divided into two categories: Post darkening stain and 4102 stain used in the 5261 method. The depth of the pre-1653 principle is actually increased by fiber surface modification in order to change or improve
Good surface properties of the fiber, increase the affinity of the fiber, used for coating, dyes, coloring materials are better absorbed, attached; also, by changing the solubility of the dye in the solution, or in the dye and other methods of structural changes in order to improve the dyeing properties.
The test focuses more and more on the use of dark colorants. The principle is to change the optical properties of the fiber surface to increase the depth in order to obtain an obvious dark effect. This kind of deep agent does not meet the requirements, or the deep dyeing amount of dark dye products dyed finished products, has a very good practical value. Test. Research on the effect of increased reagent on cotton fabric and the depth of reactive dye depth, the change from the previous tone depth, the depth of increased agent relationship and the amount of increased depth effect, and the depth treatment with increased color fastness.
