Polyester spinning before the coloring is the polyester masterbatch dissolved or dispersed in the polyester spinning solution for melt spinning, the direct preparation of colored polyester fiber of the new technology is to solve the polyester dyeing the most difficult way, the process characteristics are as follows:

(1) environmental protection is good, good health before spinning the coloring agent for the solvent dyes, without the disabled structure and composition, the human body does not cause harm. At the same time as the dyeing before dyeing can withstand more than 300 ℃ high temperature, spinning process without any gas and wastewater discharge, dye utilization increased to 100%, therefore, color masterbatch color can be said to be environmentally friendly, health products.
(2) is conducive to the development of polyester fiber function
    The development of science and technology and the improvement of people's living standards, apparel fabrics increasingly toward the functional, diversified, flexible direction, antibacterial, antistatic, flame retardant, far infrared, anti-ultraviolet and other functional fibers have successively developed, , Flame retardant, anti-bacterial, anti-ultraviolet fabric and other functional fabrics on the market, enriching people's lives, all this is achieved through the melt spinning; Therefore, masterbatch not only for polyester fiber color opened up the road, and poly The ester fiber gives the new function to open the way.

(3) low cost: the cost of dyeing is the consumption of energy and additives. Spinning before dyeing reduces the dyeing process of dyeing and finishing equipment and multi-channel fibers or fabrics, removes the dyeing auxiliaries, combines each pigment molecule into the target product, fundamentally eliminates the dye emission, reduces the consumption of raw materials, To avoid the environmental pollution, reducing the cost of dyeing, saving a huge amount of pollution control costs, there are reports, "polyester spinning before coloring and fiber dyeing compared to the production of 100 tons of liquid dyeing polyester staple fiber, can save 10,000 tons of water, saving Gas 16,500 cubic meters, saving electricity 5.6 million degrees. "" Fiber dyeing per 100 kilograms of products, can produce about 10 tons of wastewater. " According to the survey, the average coloring cost of dyeing is about 4,000 yuan, while the use of masterbatch spinning before coloring, the tanning cost of the average cost of only about 1,200 yuan, we can see before spinning color not only save a huge amount of pollution charges, and coloring only dyeing Of the third, that is, the cost of dyeing to more than three times the color of the liquid.

(4) high color quality: conventional dyeing as mentioned above is mainly used in the high temperature and high temperature under the conditions of high temperature and pressure. However, due to the production of fiber and physical and chemical treatment is difficult to ensure that the internal structure of the crystal area and the uniform distribution of the area, the dye crystal form, dispersion performance, dyeing rate and other general are often different, so the dyeing process is often easy to produce Color, stain, color flowers and other dyeing defects. Spinning before spinning is the coloring agent and the true color of the slices before the spinning, evenly mixed, and then by the melt filter, and then spinning, so the fiber dyeing uniform, regardless of batch size, color uniformity can be maintained, batch and The batch will not appear between the unacceptable color. From the structure of the fiber before dyeing, the colorant and the polyester form a consistent uniform solid solution, light fastness, washability, abrasion resistance and other fastness than conventional dyeing.

(5) the use of simple spinning before the color of polyester production, fiber use without any special requirements, the original spinning equipment, the existing production process. Especially when the polyester and other fibers blended intertwined, the use of polyester fiber does not only reduce the dyeing process, so that is not suitable for high temperature, high pressure dyeing conditions of fiber and polyester blended intertwined and easy to achieve the fabric pre-designed style. So spinning before the coloring to a certain extent, it can be said that no investment in the dyeing plant, is to use advanced technology to solve the dyeing and finishing "bottleneck" one of the shortcuts.
