Key points of chemical material operation1. Check the accuracy of the prepared dyes and chemicals according to the prescription list. When disperse dyes are used to make materials, generally use cold water to beat them and mix them evenly (stirring with a mixer for about 20-30 minutes), and then dil Read More

What is Amylase and its application? Amylase is the general name of enzymes that hydrolyze starch and glycogen. It usually catalyzes the hydrolysis of starch slurry on fabrics by amylase. Due to the high efficiency and specificity of amylase, the desizing rate of enzyme desizing is high and the desi Read More

What is Desizing? Desizing (desize) refers to the process of treating fabrics with acids, alkalis, enzymes, etc., to remove the slurry rhyme added to the warp yarns during weaving. The purpose is to facilitate subsequent processing such as refining. Before fabric weaving, warp yarns are generally su Read More

The nature of cationic dyesSolubilityThe salt-forming alkyl and anionic groups in the cationic dye molecule affect the solubility of the dye. In addition, if there are anionic compounds in the dyeing medium, such as anionic surfactants and anionic dyes, they will also combine with cationic dyes to f Read More
