What are the characteristics of polyester yarn?

Pure polyester yarn is made by spinning polyester staple fiber, and its staple fiber has different categories. From the length, there are cotton fibers, the length is about 37 mm, and there are medium-length fibers, and the length is 51 mm-57. Millimeters, hairy fibers, 75 mm-105 mm in length.
　　 There are fine denier fibers from the thickness, around 1.5D, coarse denier fibers around 5D, and intermediate 3D fibers, of course, there are finer ones such as 1D and even ultra-fine fibers such as 0.1-0.5D.
The yarn is very thin, such as 50 yarns and 60 yarns. It is easy to spin evenly with fine denier fibers. If the fiber is longer, it can increase the cohesion and strength. The spun yarn feels fine. On the contrary, thick denier yarn feels rough and has a better hair feel. and many more. When spinning polyester spun yarn, it is necessary to clarify the thickness of the fiber and the length, and generally know where the staple fiber is produced.

Characteristics of polyester yarn
　　Polyester yarn: It is made by spinning polyester staple fiber. Polyester fabric has high strength and elastic recovery ability. Therefore, it is durable, wrinkle-resistant and non-ironing. Polyester fabric is not deformed and has good wash and wear properties.
　　 Polyester is a fabric with better heat resistance among synthetic fabrics. It is thermoplastic and can be made into pleated skirts with long-lasting pleats. Polyester fabric has good light resistance, and its light resistance is better than natural fiber fabrics. Especially the light fastness behind the glass is very good, almost as good as acrylic. Polyester fabric has good resistance to various chemicals. Acids and alkalis do not damage it too much, and they are not afraid of molds and insects. Polyester is widely used in the manufacture of clothing and industrial products.
Polyester is used as clothing fiber, and its fabric achieves the effect of no wrinkle and ironing after washing. Polyester is often blended or interwoven with various fibers, such as cotton polyester, wool polyester, etc., which are widely used in various clothing and decorative materials. In industry, polyester can be used in conveyor belts, tents, canvases, cables, fishing nets, etc., especially polyester cord used in tires, which is close to nylon in performance. Polyester can also be used for electrical insulation materials, acid-resistant filter cloth, and medical industry cloth.
