Textile auxiliaries: Textile auxiliaries are necessary chemicals in the production and processing of textiles. Textile auxiliaries play an indispensable main role in improving the product quality and added value of textiles. They can not only give textiles various special functions and characteristics, such as softness, anti-wrinkle, anti-shrinkage, waterproof, antibacterial, antistatic, flame retardant And so on, can also improve dyeing and finishing technology to save energy and reduce processing costs. Textile auxiliaries are crucial to improving the overall level of the textile industry and their role in the textile industry chain.

The types of textile auxiliaries include:

Pre-treatment auxiliary series: pre-treatment, cleaning, anti-dyeing.

Physical additives series: Ternary copolymer silicone oil, amino silicone oil, smooth and bright, soft oil, film, resin, whitening, enzyme.

Dyeing auxiliary series: dyeing and fixing.

Functional finishing agent series: functional finishing agent.

Printing series: Printing series.

Washing auxiliary series for wool finishing: soft, hand-feel, decontamination finishing, and decontamination finishing.

Textile Dyes: Textile dyes are dyes used in textile dyeing. They are mostly plant extracts such as plant fruits and tree sap, and are also rich in natural chemical extracts such as coal tar. It is divided into natural dyes and constituent dyes, and most of them are constituent dyes on the market. Textile dyes have good colorability, are not easy to fade, and are not easy to fade after washing. After the textile is colored, the hand feel is not changed much, and it will not become hard. But the color is less beautiful and saturation than acrylic.

The types of textile dyes include: reactive dyes, acid dyes, disperse dyes, and leather dyes.

1. Reactive dyes: Reactive dyes are mostly used in cellulosic fabrics and less used in proteins. It is characterized by bright color, light fastness, washing and collision fastness.

2. Acid dyes: Acid dyes are mostly suitable for protein fibers, nylon fibers and silk. It is characterized by bright color, but poor washing fastness, excellent dry cleaning fastness, and widely used in natural dead dyeing.

3. Disperse dyes: disperse dyes, suitable for viscose, acrylic, nylon, polyester, etc., with different washing fastnesses, polyester is better, viscose is poor.
