Problems solved by technology

Polyester fiber, such as micro-denier polyester fiber, has high strength, wear resistance, excellent resilience and heat setting characteristics, can maintain the bending deformation formed when heated, and is light and thin, so it is a popular material in sportswear, but , its level dyeing and dyeing depth are poor, so it is easy to cause uneven dyeing in the dyeing process
The basic chemical composition of viscose fiber is the same as that of cotton fiber, so it is close to cotton fiber in some properties, for example, it has better softness; at the same time, viscose fiber has the smoothness of silk fiber, and its hygroscopicity and air permeability And the gloss is better than cotton fiber. Therefore, the dyeing performance of viscose fiber is better, it is easier to color than cotton fiber, and the color is pure and bright, and the color spectrum is the most complete; however, the biggest disadvantage of viscose fiber is that it is wet. Poor strength, the fabric is easy to wrinkle and difficult to restore
By blending micro-denier polyester fiber and viscose fiber, a soft, moisture-absorbing, breathable and strong blended fabric can be obtained. However, the properties of these two fibers are quite different. The traditional dyeing and finishing process needs to remove the blended fabric. Oil, polyester dyeing, cleaning, viscose dyeing, soaping and other processes can complete the dyeing, which consumes a lot of energy. With the increasing pressure of environmental protection, various production costs are also increasing
[0003] For the dyeing of micro-denier polyester and viscose fibers, the traditional method is to use the "two-bath method", first dyeing micro-denier polyester fibers, and then dyeing viscose fibers after draining, which consumes a lot of energy; Bath two-step method", select salt-resistant disperse dyes and high-temperature-resistant direct dyes for dyeing, but because of the need to use multiple dyes, add in several times, resulting in long process time, complicated operation, direct dyes are unstable at high temperatures, viscose At the same time, in order to solve the dyeing defects of direct reactive dyes under high temperature conditions, multiple dyes are generally used. However, the disadvantage of using multiple dyes is that it is difficult to match colors and poor reproducibility
Therefore, there is currently no method to realize the one-step dyeing of micro-denier polyester and viscose fibers in the same bath.
