Features and Advantages

1. Excellent trans-dyeability, which can effectively solve all kinds of defects of polyester and its blended fabrics after dyeing, and the colored light remained basically unchanged after repairing.            

2. The special activator component in the composition can retard dyeing and prevent the secondary condensation of dyes at low dyeing temperature, and play a strong role in promoting dyeing at high temperature. Therefore, the dyeing of polyester and its blended fabrics with WF-4016 can not only improve levelness, but also increase the rate of color formation.            

3. It is suitable for dyeing polyester cheese yarn. Because of its strong diffusivity, it can effectively avoid the problem of color difference between inner and outer layers of cheese yarn.
