Liyuan Fiber talks about the performance characteristics of polyester low elastic yarn

    Polyester low elastic yarn is a type of textured yarn of polyester chemical fiber. It is made of polyester chip (PET) as raw material, and polyester pre-oriented yarn (POY) is spun at high speed, and then processed by drafting and false twisting. It has the characteristics of short process, high efficiency and good quality. Polyester low elastic yarn has the characteristics of high breaking strength and elastic modulus of general polyester, excellent heat setting, good resilience, heat resistance, light resistance, strong corrosion resistance, easy washing and quick drying, etc. It also has bulky properties. High performance, good heat insulation, comfortable hand feel, soft luster and so on.

    Polyester low elastic yarn also has a sewing function, and overlocking is also called overlocking. This process is required for all pieces of clothing. Since the main purpose of the stitching is to keep the yarn of the piece from falling apart, the strength of the stitching thread is not high. In order to save costs, the overlock thread is generally made of polyester network yarn without twisting, and its strength is lower than that of sewing thread. The difference between it and ordinary sewing thread is that the overhang thread is made of polyester filament without twisting, while the sewing thread is made of polyester staple fiber and twisted.

    Below, Liyuan Fiber Co., Ltd. will talk to you about the performance characteristics of polyester low elastic yarn:

1. High strength. The short fiber strength is 2.6 to 5.7 cN/dtex, and the high tenacity fiber is 5.6 to 8.0 cN/dtex. Due to its low hygroscopicity, its wet strength is basically the same as its dry strength. The impact strength is 4 times higher than that of nylon and 20 times higher than that of viscose fiber.

2. Good elasticity. The elasticity is close to that of wool, and it can almost fully recover when the elongation is 5% to 6%. The wrinkle resistance exceeds other fibers, that is, the fabric does not wrinkle and has good dimensional stability. The elastic modulus is 22~141cN/dtex, which is 2~3 times higher than that of nylon.

3. Heat resistance and thermal stability are good in synthetic fiber fabrics. a

4. The surface of polyester is smooth, and the internal molecules are closely arranged.

5. Good wear resistance. The abrasion resistance is second only to nylon with good abrasion resistance, and it is better than other natural fibers and synthetic fibers.

6. Good light resistance. Lightfastness is second only to acrylic.

7. Corrosion resistance. Resistant to bleaches, hydrocarbons, ketones, petroleum products and inorganic acids. Dilute alkali resistance, not afraid of mildew, but hot alkali can make it decompose.

8. Poor dyeability, but good color fastness, not easy to fade.

   Liyuan Fiber Co., Ltd. specializes in the production of polyester low elastic yarn, polyester cord, nylon cord and other textile threads.
