In the modern textile industry, printing is a common process. Printing is a method of creating different patterns and color effects by printing pigments or dyes on the surface of fabrics. However, in order to achieve the best printing effect, textile auxiliaries are needed. This article will introduce the commonly used textile auxiliaries in printing, their functions and scope of application in detail.

1. Fixing agent

The fixing agent is a textile auxiliary that is mainly used to maintain the fastness of pigments or dyes after printing. Since textiles are affected by various factors in daily use, such as friction, washing and sunlight, fixing agents are needed to ensure that the printing effect is sustainable. Commonly used fixing agents are cationic fixing agents and anionic fixing agents. Cationic fixing agents are suitable for situations where the printing pigments and dyes themselves carry anions, while anionic fixing agents are the opposite and are suitable for situations with cations.

2. Dispersants

Dispersants are also important in printing. It can disperse pigments or dyes in liquids and prevent them from aggregating with each other during the printing process. Dispersants help maintain printing quality and consistency. The choice of dispersant should be based on the type of pigment or dye used.

3. Slurry

Slurry is a commonly used textile auxiliary agent, which is usually used to improve the quality of printing. Slurry can make pigments or dyes adhere better to the surface of fabrics, creating clearer patterns and more saturated colors. Slurry is usually a mixture of resin, fixing agent and other auxiliaries. Choosing the right slurry can improve the printing effect.

4. Defoamer

Defoamers are usually used to control the generation of foam during the printing process. Foam may hinder the contact between pigments or dyes and the surface of fabrics, thereby affecting the quality of printing. Defoamers can reduce the generation of foam and maintain the stability of the printing process.

5. Solvent

Soluble agent is a commonly used textile auxiliary agent, which is usually used to dissolve difficult pigments or dyes. Solvent can change the molecular structure of pigments or dyes, making them easier to dissolve and match. The choice of solvent should be based on the type of pigment or dye used.

6. Resin

Resin is a commonly used textile auxiliary agent that can improve the quality of printing. Resin can make pigments or dyes adhere better to the surface of fabrics, and can increase the hardness and wear resistance of fabrics. The choice of resin should be based on the desired effect.

Textile auxiliaries in printing are very important. We need to choose different auxiliaries for different printing effects. During the printing process, textile auxiliaries can improve quality, increase wear resistance and enhance its appearance. Therefore, before printing, it is very important to understand the uses and functions of different auxiliaries.
