In the textile printing and dyeing industry, fabric wettability and feel are important indicators of product quality. Good wettability helps the uniform distribution of dyes and auxiliaries on the fabric, while excellent feel can enhance the wearing experience of consumers. To achieve these goals, chelating agents in textile auxiliaries play a key role.

The role of chelating agents in improving fabric wettability

The wettability of fabric refers to the ability of liquid to spread and penetrate on the surface of fabric. During the printing and dyeing process, if the wettability of the fabric is poor, dyes and auxiliaries will be difficult to penetrate evenly, resulting in uneven dyeing or residual auxiliaries. Chelating agents can effectively improve the wettability of fabrics through their unique chemical properties.

Chelating agents can form stable complexes with metal ions (such as calcium, magnesium, etc.) on the surface of fabrics, thereby neutralizing or removing these ions that have an adverse effect on wettability. At the same time, chelating agents can also reduce the interfacial tension between the liquid and the surface of the fabric, making it easier for the liquid to spread and penetrate on the fabric.

Technical knowledge of our company's special chelating dispersant for textile auxiliaries

As a professional manufacturer of textile auxiliaries, our company's special chelating dispersant for textile auxiliaries has shown excellent performance in improving fabric wettability. This chelating dispersant adopts advanced copolymer technology and combines multiple functional groups. It has strong chelating ability, good dispersibility and excellent wetting performance.

Specifically, our chelating dispersant can react with metal ions on the surface of the fabric through specific groups in its molecules to form a stable complex, thereby neutralizing or removing these ions. At the same time, the chelating dispersant can also reduce the interfacial tension between the liquid and the fabric surface, making it easier for dyes and auxiliaries to spread and penetrate on the fabric.

Application Cases

Case 1: A printing and dyeing factory improves the wettability of cotton fabrics

Problem: When dyeing cotton fabrics, the printing and dyeing factory found that the dye was difficult to penetrate evenly, resulting in uneven dyeing.

Solution: Add Chint New Materials' special chelating dispersant for textile auxiliaries in the pre-dyeing process.

Effect: After treatment, the wettability of cotton fabrics has been significantly improved, the dye can penetrate evenly, and the dyeing effect is more uniform and bright.

Case 2: A textile company improves the feel of silk

Background: The textile company produces silk products, but customers report that the silk feels hard and not soft and comfortable enough.

Solution: Add Chint New Materials' special chelating dispersant for textile auxiliaries in the finishing process and adjust the relevant process parameters.

Effect: The treated silk products feel soft and comfortable, and maintain the original luster and color, which has been well received by customers.
