What are the functions of scouring agents in dyeing and finishing?
Remove fiber impurities:
In the production process of textiles, some impurities such as grease, wax, pectin, etc. are often attached to the fiber surface. These impurities not only affect the penetration of dyes, but also may cause uneven dyeing. Scouring agents can effectively decompose and remove these impurities, creating favorable conditions for subsequent dyeing processes.
Improve dye permeability:
Wetting Agent Sylic P1400Scouring agents can reduce the tension on the fiber surface, making it easier for dyes to penetrate into the fiber. This not only improves the uniformity of dyeing, but also enhances the fastness of dyeing, making the color brighter and more durable.
Optimize dyeing and finishing process:
The use of scouring agents can simplify the dyeing and finishing process and reduce production costs. At the same time, it can also reduce the defective rate in the dyeing process, improve product quality and production efficiency.
Environmental protection and safety:
Modern scouring agents mostly use environmentally friendly formulas, which are not only harmless to the human body, but also have little impact on the environment. This is in line with the current green and environmentally friendly production concept and is conducive to the sustainable development of enterprises.
Composition and mechanism of action of scouring agent:
Scouring agent is mainly composed of various anionic and nonionic surfactants and appropriate additives, and is a compound with a washing effect obtained through a certain ratio method. These ingredients have good penetration, emulsification, dispersion, and cleaning properties, and are alkali-resistant, high-temperature-resistant, low-foaming, safe and non-toxic.
Application examples of scouring agent in dyeing and finishing process:
Before dyeing and finishing of textile fibers, scouring agents are widely used to remove natural impurities on fibers and pulp and oil agents during textile weaving to improve the water absorption and softness of fibers, and facilitate the adsorption and diffusion of dyes during printing and dyeing process.
