Problems solved by technology

[0004] People's requirements for textiles are not only functional, but also multi-functional for the same fabric. Because there are many problems in compatibility between single-functional finishing agents, it is difficult to finish in the same bath. In order to meet the multi-functional requirements of fabrics, Often the fabric needs to be finished multiple times, which not only complicates and increases the cost of finishing, but also makes it difficult to ensure good versatility
[0005] Dual-reactive dyes have the characteristics of high color fixation rate, low hydrolysis rate and environmental protection requirements. They have gradually become the main dyes of cotton fabrics. However, their low color fastness to light is often difficult to meet the requirements of use. Anti-UV finishing to solve this problem, but the effect is not obvious
