1. Choose appropriate dyes: Choosing high-performance dyes is the foundation for improving various color fastness. For example, the washing fastness of reactive dyes is better than that of direct dyes, while the washing fastness of insoluble azo dyes, reducing dyes, and sulfide dyes is even better.

2. Optimize dyeing and finishing processes: Developing a reasonable dyeing and finishing process is the key to ensuring various color fastness. This includes strengthening processes such as washing, fixing, and soap washing, as well as selecting the correct dyeing process.

3. Use environmentally friendly additives: In order to improve certain fastness of textiles, specialized additives can be used. For example, in order to improve the wet rubbing fastness of deep colored cellulose fiber products, specialized additives that can enhance the wet rubbing fastness of textiles can be selected.

4. Conduct necessary tests: Conduct necessary tests on textiles, such as azo testing, to ensure their safety. These tests can help identify potential security issues and take corresponding measures for improvement and monitoring.

5. Adhere to relevant standards and regulations: Ensure that textiles comply with global regulatory requirements, such as the EU REACH regulation, SVHC List of Substances of Very High Concern, CPSIA Consumer Improvement Act, etc.
