The existing spinneret used for producing nylon fibers has circular spinning holes, and the fibers produced from the circular holes have a solid structure inside, which is tightly arranged and lacks hydrophilic structures between molecules. Therefore, the moisture regain is low, the moisture absorption and dyeability are poor, and the surface is lubricated. When light shines on the surface, it simply forms diffuse reflection, resulting in poor luster and difficulty in meeting people's needs.

In addition, in the existing production of nylon, in order to give the newborn fibers a specific color, the method of adding color masterbatch in the slicing melt extrusion screw is generally adopted. The existing color masterbatch injection equipment mainly includes the slicing melt extrusion screw and the color masterbatch addition equipment located in front of the slicing melt extrusion screw. However, the existing color masterbatch addition equipment can only work in the power frequency state and does not have the function of variable speed increase. It cannot be adjusted according to production requirements or changes in production status, making it difficult to control the increase of color masterbatch. The color uniformity of nylon fibers is poor, and the production speed and quality of nylon color yarn are low.
