According to Zhihu, there are several ways to enhance the strength: 1. Optimizing production process: Optimizing production process, such as adjusting spinning temperature, can improve the strength of nylon stretch yarn.
2. Changing the cross-sectional shape of fiber: By changing the cross-sectional shape of fiber and increasing the surface area of fiber, the strength and wear resistance of nylon elastic yarn can be improved.
3. Blending other fibers: Blending nylon stretch yarn with other fibers can make use of the characteristics of other fibers to improve the strength and wear resistance of nylon stretch yarn. For example, blending nylon stretch yarn with cotton, hemp and other fibers can improve the friction and cohesion between fibers, thus improving the strength of nylon stretch yarn.
4. Selection of high-strength fiber: selecting high-strength fiber to produce nylon elastic yarn, such as high-strength polyamide fiber, can improve the strength and durability of nylon elastic yarn.
