Physical and Chemical Properties | A reactive cationic polymer, a light yellow viscous liquid. It can be miscible with water in any ratio and can be mixed with non ionic or cationic additives. Formaldehyde free color fixing agent YSZ molecules contain active groups that can covalently bond with polar groups on fibers, such as - OH, - NH2, and have cationic properties. It is easy to bond with anions of dye molecules through ionic bonds. At the same time, it can also crosslink into a large molecular network of insoluble films to further block the dye, increase the binding between the dye and the fiber, and prevent the dye from dissolving and falling off during wet treatment, Therefore, it significantly improves the wet treatment fastness. |
Use | This product can be used for fixation treatment of reactive dyes and direct dyes. |
This product is non-toxic and is stored and transported as a general chemical.
Firstly, diethylenetriamine is used as the raw material to react with epichlorohydrin to introduce reactive groups (- OH and - Cl). The product reacts with acryloyl chloride to obtain acrylamide derivatives with reactive groups, which are the monomers of the polymerization reaction. The above monomers were polymerized using 2,2-azobis (2-methylpropioximic acid) as an initiator to obtain a cationic polymer containing reactive groups, which is the fixing agent YSZ.
