In recent years, the textile industry has continued to innovate in the development of science and technology, fashion, and green fields, especially when the "low-carbon economy" and energy saving and emission reduction have attracted the attention of the industry. my country's chemical fiber industry is looking for a cleaner dyeing method. , Solve the problem of environmental pollution in the dyeing process for a long time. At present, the use of masterbatch method (including polyester masterbatch) for pre-spinning coloring is a recognized environmentally friendly coloring method.

Generally speaking, the production of traditional colored fabrics requires multiple processing links such as spinning (yarn), high-temperature and high-pressure dyeing, warping weaving, etc. The printing and dyeing process uses conventional spinning white polyester filaments with disperse dyes Dyeing under high temperature and high pressure not only has a long process flow and high energy consumption at high temperature, but also discharges a large amount of printing and dyeing wastewater, causing certain pollution to the environment.

The coloring of masterbatch (including polyester masterbatch) has three main advantages:

1. It can save a lot of manpower and energy.

2. It can greatly reduce the discharge of industrial wastewater.

3. The cost advantage is obvious in the light-colored or dark-medium color field.

Experiments show that compared with printing and dyeing, the pre-spinning coloring process has less process flow, no process waste water, and low energy consumption. The electricity consumption per ton of coloring is about 50 degrees, and the dye utilization rate is 100%. From the perspective of coloring quality, the color is uniform and High color fastness, light resistance, washing resistance and rubbing resistance. According to statistics, my country's polyester chemical fiber output exceeded 40 million tons in 2017. Among them, the output of black fiber is 9.1 million tons, and the output of other colors is 4.9 million tons. As domestic environmental protection requirements become more stringent and labor costs are getting higher and higher, it can be expected that the printing and dyeing capacity will gradually decrease for a long time in the future. In the long run, masterbatch (including polyester masterbatch) will be used for dope The number of coloring factories will increase. According to industry insiders, the development of pre-spinning coloring technology is very important to promote the sustainable development of the chemical fiber industry and the entire textile industry, and more importantly, the long-term social benefits. The pre-spinning coloring technology can solve the high energy consumption, The problem of high pollution has helped the textile industry to achieve breakthroughs in energy conservation and emission reduction, bringing long-term benefits to society and the industry.
