AI Technical Summary

Technical Problem

Existing nylon fibers, when used in multifunctional layering processes, are costly and their dyeing performance cannot meet the application requirements, making it difficult to combine multiple functions such as cooling sensation, UV resistance, and moisture absorption.

Method used

Design a spinneret for producing PA6 biomimetic fibers. The cross-section of the spinneret is formed by connecting several leaf-shaped lines end to end to form a centrally symmetrical shape, creating grooves to increase the specific surface area. The distance from the center point of the spinneret to the connection point of the adjacent leaf-shaped lines is greater than the distance between the centers of the spinnerets, achieving multi-functional superposition.

Benefits of technology

It achieves multi-functional layering of PA6 fibers, improving the fiber's absorption and release properties, cooling effect, and dyeing performance, while also increasing the fabric's bursting strength to meet the requirements of high-end sportswear and outdoor apparel.
