Practical significance-the dry and wet rubbing fastness of the finished product can be improved to above 3-4, which can meet the first-class quality requirements of customers. The wet rubbing fastness improver can be used in the same bath together with the fixing agent and the softening agent without adjusting the pH value, which can simplify the production process, shorten the production time and greatly improve the production efficiency.
This passage is going to talk about the following questions of the wet rubbing fastness improver:
(1) Prospect of the wet rubbing fastness improver
(2) Performance and use of the wet rubbing fastness improver
(3) Precautions for using the wet rubbing fastness improver
Since the 1990s, China has developed rubbing fastness enhancers. After decades of development, progress has been made. Although all major domestic auxiliary auxiliaries’ manufacturers sell their products on the market, they still lack a full range of rubbing fastness enhancers. The wet rubbing fastness of cashmere fabrics is significantly improved, and there is no selectivity for dyes, which affects the feel of the fabric. Very small, no need to adjust the pH value of the working fluid in use.
Certain rubbing fastness enhancers on the market are only suitable for fabrics dyed with reactive dyes. There are also some that are useful for vulcanized direct dyed fabrics and need to be adjusted during use. The pH value of the working fluid may cause the problem of color increase, and the hand feeling of some finished fabrics is difficult.
The wet rubbing fastness improver is a high molecular compound and does not contain formaldehyde. It is suitable for the fixing and finishing of reactive, vulcanized, direct and vat dyed fabrics. The wet rubbing fastness improver is easy to penetrate and adsorb. The wet rubbing fastness improver can form a lake with the dye inside the fiber, making the adhesion of the dye on the fiber stronger. The wet rubbing fastness improver can be bathed with silicone oil. The wet rubbing fastness improver is soft to the touch and the color becomes smaller, which can obviously improve the dry and wet fastness, and the wet rubbing fastness of the dark fabric can be improved by 2-3 levels
The wet rubbing fastness improver can be used for the finishing of dark fabrics. It has no selectivity to dyes and can improve the fastness of wet rubbing reactive dyes, direct dyes, sulfur dyes and vat dyes to level 3 or higher.

It has an excellent effect on improving moisture. The color fastness of rubbing fabric has little effect on the fabric. Possible effects are the color and feel of the fabric.
After finishing in the same bath, the fastness of the colored fabric to friction, soaping and perspiration reaches above level 4. This not only improves the performance of wearing dark fabrics, but also simplifies the production process of the dyeing factory, and has good economic and social benefits.
