The two main advantages of pre-spinning coloring with polyester masterbatch are as follows:

(4) Polyester masterbatch for pre-spinning coloring is environmentally friendly and beneficial to health. The colorant used for pre-spinning coloring is a solvent dye, which does not contain prohibited structures and ingredients and does not cause harm to the human body. At the same time, since the dye used for pre-spinning can withstand the high temperature above 300 °C, there is no gas and waste water discharge during the spinning process, and the dye utilization rate is increased to 100%. Therefore, the masterbatch coloring can be said to be an environmentally friendly and healthy product.

.

(5) The pre-spinning of polyester masterbatch is beneficial to the functional development of polyester fiber.

With the development of science and technology and the improvement of people's living standards, apparel fabrics are increasingly developing in the direction of functionalization, diversification and flexibility. Antibacterial, antistatic, flame retardant, far infrared, anti-ultraviolet and other functional fibers have been successfully developed. Functional fabrics such as flame retardant, antibacterial and anti-ultraviolet fabrics have been put on the market, enriching people's lives, all of which are achieved by melt spinning; therefore, masterbatch not only opens the way for polyester fiber coloring, but also gathers Ester fibers open the way to new functions.
