The textile industry is an extremely important industry that provides people with a variety of fabrics, clothing and textiles needed in daily life. In this industry, auxiliaries are very necessary because they can improve the quality, performance and appearance of fibers and fabrics. Now let's learn about the types of auxiliaries used in the textile industry and how to expand their applications.

Textile auxiliaries are special chemicals added to fibers or fabrics. They can help fibers or fabrics to be processed quickly and easily, making them more dimensionally stable, abrasion-resistant, color stable and glossy. In the textile industry, there are many types of auxiliaries, which can be used to pre-treat, dye, print, and finish fibers and fabrics as needed. In the textile industry, commonly used auxiliaries include:

1. Dyeing auxiliaries: Dyeing auxiliaries are chemical agents that make fabrics dye more evenly and have higher color fastness, including dispersants, dye locking agents, reducing agents and brighteners.

2. Printing auxiliaries: Printing auxiliaries are mainly used in printing processes, which can help printing dyes adhere to fabrics and make patterns more vivid and clear.

3. Pre-finishing agent: Pre-finishing agent is a chemical agent added before fabric dyeing or printing, which can make the surface of the fabric smoother and softer.

4. Post-finishing agent: Post-finishing agent is a chemical agent added after fabric dyeing or printing, which can make the fabric smoother, more resistant to friction and less prone to pilling.

5. Antibacterial agent: Antibacterial agent can form an antibacterial film on the surface of the fabric, inhibit the growth of microorganisms such as bacteria and mold, and keep the fabric hygienic.

6. Surfactant: Surfactant has strong surface activity, which can make the fiber absorb moisture quickly, more breathable and more comfortable to wear.

7. Flame retardant: Flame retardant can make the fabric have flame retardant properties by chemically treating the fabric, effectively avoiding the occurrence of fire accidents.

How to expand the application of auxiliaries in the textile industry? First, we need to conduct in-depth research on the physical and chemical properties and application characteristics of various auxiliaries, and explore more application areas, such as new materials, new processes, etc. Secondly, strengthen international cooperation and exchanges, introduce more advanced textile auxiliaries technology, and improve the international competitiveness of my country's textile industry. In addition, environmental protection and sustainable development are also important considerations for the development of the textile industry. When using auxiliaries, attention should be paid to reducing the impact on the environment.

Auxiliaries are indispensable chemicals in the textile industry. They can improve the performance of fibers and fabrics, increase the technical content of the industry, and also promote the textile industry to develop in a more intelligent, environmentally friendly and sustainable direction.
