Viscose Filament Yarn is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dihydric alcohol. It is a kind of synthetic fiber obtained by melt spinning polyester as raw material. The main variety is polyethylene terephthalate fiber, usually polyester fiber refers to this fiber, which is called polyester in China. It is the largest variety of synthetic fibers at present. Polyester fiber fabric is an ideal textile raw material.

Its recovery ability (ie elasticity) to deformation such as elongation, compression and bending is close to that of wool. The fibers are not easily deformed, and the processed fabrics do not wrinkle after washing, and can not be ironed. It has strong drug resistance and is not prone to mildew and insect damage, so it is relatively simple to store. The pleats formed with thermoplastic have high strength and good durability. The strength of polyester fiber is generally 44~71cN/dtex, which is 1 times higher than cotton and 3 times higher than wool.

It also has good heat resistance, light resistance and abrasion resistance, and can be used within -70~170℃. Polyester fiber is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dihydric alcohol. It is commonly known as polyester, which is widely used in clothing fabrics. Polyester has excellent wrinkle resistance, elasticity and dimensional stability, good insulation properties, and a wide range of uses.

It is suitable for clothing of men, women and children. What kind of fabric is polyester fiber? Polyester fiber has high strength and elastic recovery, so it is durable, wrinkle-resistant and easy to iron. It has good light fastness, except that it is worse than acrylic fiber, its light fastness is better than that of natural fiber fabrics, especially the light fastness behind glass is very good, almost comparable to acrylic fiber. In addition, polyester fabrics have good resistance to various chemicals, and are not damaged by acids and alkalis. At the same time, they are not afraid of mold or insects.
