Polyester low elastic yarn (referred to as DTY) is a type of textured yarn of polyester chemical fiber. It is made of the polyester chip (PET) as raw material, using high-speed spinning polyester pre-oriented yarn (POY), and then through drafting and false twisting. become. It has the characteristics of short process, high efficiency, and good quality. In addition to the 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 high bulkiness, It has the characteristics of good heat insulation, comfortable hand feeling, and soft luster. It is an ideal raw material for knitting and weaving and is suitable for making clothing fabrics, bedding, and decorative items. Polyester low-elastic yarn also has a sewing function, which is required for all clothing pieces. Since the main purpose of stitching is to prevent the yarn of the pieces from falling off, the strength of stitching is not required.

Whether it is bedding or all kinds of clothing in people's lives, polyester low-elastic yarn, a chemical fiber raw material, is inevitably applied in the sewing process. Often people use this material for the use of overlock lines. The reason why polyester low elastic yarn can stand out from so many raw materials is precise because of the many advantages of this chemical fiber product, so it has received more and more attention and widespread attention.

Generally, polyester cords are widely used in the manufacture of clothing fabrics and industrial products and have excellent shaping properties. Polyester, also known as terylene, is the simplest of the three synthetic fibers, and the price is relatively cheap. In addition, it is durable, elastic, not easily deformed, corrosion-resistant, insulating, stiff, easy to wash and quick-drying, etc. Features are loved by people. Polyester is the most heat-resistant fabric in synthetic fabrics. It has thermoplastic properties and can be made into pleated skirts with long-lasting pleats. At the same time, the polyester woven low elastic yarn has poor melting resistance, and it is easy to form holes when encountering soot and sparks. Therefore, try to avoid contact with cigarette butts, sparks, etc. when wearing.

Low elastic yarn also has a sewing function. Overlocking is also called overlocking. In English, it is 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 off, 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.
