Different from traditional color- fixing agents, this product does not affect the style, hydrophilicity and hand-feel of the fabric (like the stiffness of the fabric after color fixation, etc.), has very little effect on the color and does not affect the subsequent color matching. It also differs from conventional fixing agents in any odor, such as sour or ammonia. In addition, it has low viscosity, in more and more automated input chemical raw materials and auxiliary materials system use, it can solve the traditional color fixing agent viscosity problem be easy to dilute, improve the accuracy of automated input chemical raw materials and auxiliary materials. Moreover, the characteristics of high content and super high-cost performance can reduce production costs. It does not contain formaldehyde and is a green and environmentally friendly product.
