Textile Auxiliaries---Formaldehyde-free Fixing Agent

The Aldehyde-free fixing agent series is the main product of jervay.
The Aldehyde-free fixing agent product series is mainly for the fixing treatment of cotton fabrics. It is used to fix the printing fabrics such as direct dyes, reactive dyes and sulfur dyes. It is a highly concentrated green product. The product can effectively improve the soaping fastness and the water fastness. It has excellent color fixation effect on red, royal blue and dark black fabrics. The original color of the fabric has not changed much. Does not affect the original feel of the fabric.
We conducted multiple sets of comparative tests on the products. After comparing with peer products, our products are more effective. In market research, customers reported that the product effectively improved various fastnesses.

The principle of Fixing Agent

Although some dyes can dye brighter colors, but because of the water-soluble groups on the dyes, the fastness is not good, and the color fade and staining are serious.
The molecular attraction between the fixing agent and the fiber is used to increase the fixing strength of the fixing agent, thereby improving the color fastness. The intermolecular attraction referred to here is the key hydrogen bond attraction.
The fixing agent is used to form a film on the surface of the fiber, which increases the difficulty of dissolving the dye and improves the fastness.
Use the reactive group in the fixing agent molecule to crosslink the reactive group on the dye molecule, thereby reducing the water solubility of the dye.
