The difference between Korean velvet and Huayao fabrics

     As a cold proof tool, non inverted fabric is widely used in winter clothing, and the sales volume of dyed non inverted fabric is also good. Does anyone know the manufacturing process of dyed down fabric? Today, we will introduce the manufacturing process of dyed non inverted fabric.

It is a new dyeing method and a new trend of dyeing process to select alkali resistant disperse dyes and cooperate with special dyeing auxiliaries in alkaline dyeing of polyester and blended fabrics. The traditional disperse dyeing of pure polyester without downing can be carried out in acid bath after alkali deweighting, washing and neutralization. This not only wastes working hours, water, electricity and steam resources, but also fails to achieve the desired effect. Due to the fact that a large number of oligomers are attached to the surface of the fiber and the inner wall of the dyeing tank under acidic conditions, the finishing difficulty of the dyeing tank is increased, and the surface of the fiber becomes rough, the handle is reduced, and the problems such as color spots, color spots and color flowers are easy to appear. The alkali deweighting dyeing one bath process uses alkali resistant disperse dyes and corresponding auxiliaries to carry out alkali deweighting and dyeing under alkaline conditions.

         The one bath one-step process can overcome the problems caused by acid dyeing, improve the fiber performance and quality, greatly shorten the dyeing time, greatly reduce the water, electricity and steam consumption, and reduce the emission of pollutants together.
