How to further improve its strength and wear resistance by adjusting the raw material ratio or optimizing the spinning process?

In the production process of Polyester DTY, how to further improve its strength and wear resistance by adjusting the raw material ratio or optimizing the spinning process?

In the production process of Polyester DTY (Draw Textured Yarn), improving strength and wear resistance are key goals. By adjusting the raw material ratio and optimizing the spinning process, we can effectively achieve this goal. Here are some specific suggestions:

1. Adjust the ratio of raw materials

Choose high-strength raw materials: Increase the proportion of high-strength polyester fiber in the raw material ratio, which will help improve the strength of the final product. At the same time, you can consider using specially treated polyester fibers, such as reinforced polyester fibers, to further increase strength.
Add wear-resistant additives: Add an appropriate amount of wear-resistant additives to the raw materials. These additives can form a protective film on the surface of the fiber, reducing the friction between the fiber and external substances, thereby improving the wear resistance.
Control the mixing uniformity of raw materials: ensure that different raw materials are evenly distributed during the mixing process to avoid local proportion deviations to ensure the performance stability of the final product.

2. Optimize the spinning process

Control spinning temperature: Spinning temperature is an important factor affecting fiber properties. By adjusting the spinning temperature, the crystallinity and orientation of the fiber can be controlled, thereby affecting its strength and wear resistance. During the optimization process, it is necessary to find the optimal spinning temperature range to achieve the best fiber performance.
Optimize draw ratio and speed: Stretch ratio and speed have a significant impact on the strength and abrasion resistance of the fiber. By adjusting these parameters, the internal structure of the fiber, such as fiber orientation and crystalline structure, can be controlled to optimize its performance. Appropriate stretching ratio and speed can improve the strength and wear resistance of the fiber.
Enhanced cooling and heat treatment: During the spinning process, enhanced cooling and heat treatment help stabilize the structure of the fiber, improve the crystallinity and orientation of the fiber, thereby enhancing its strength and wear resistance.

3. Introducing advanced technology

New spinning technologies are adopted: such as melt direct spinning technology, air deformation technology, etc. These technologies can improve the internal structure of the fiber and increase the strength and wear resistance of the fiber.
Combining composite spinning technology: Composite spinning of polyester fiber and other high-performance fibers to form composite fibers with excellent properties. This method can make full use of the advantages of various fibers to achieve complementary performance.

By adjusting the raw material ratio and optimizing the spinning process, we can effectively improve the strength and wear resistance of Polyester DTY. In the actual production process, it also needs to be flexibly adjusted and optimized according to specific needs and product characteristics.
