Polyester, also known as polyester, is a synthetic fiber with several notable characteristics. Here are some of the key features of polyester:
Excellent wear resistance: The wear resistance of polyester fiber ranks among the best among all types of textile fibers. Its wear resistance is second only to nylon, which has the best wear resistance. It is 20 times higher than cotton fiber and 20 times higher than wool. -30 times.
Excellent elasticity: The elasticity of polyester fiber is close to that of wool. When stretched by 5% to 6%, it can almost completely recover. The wrinkle resistance exceeds that of other fibers, that is, the fabric does not wrinkle and has good dimensional stability.
Good heat resistance: Polyester fiber has good heat resistance and can be used in the temperature range of -70°C to 170°C. It has the best heat resistance and thermal stability among synthetic fibers.
Excellent light resistance: Polyester fiber has better light resistance. In addition to being worse than acrylic fiber, its light resistance is better than natural fiber fabrics. Especially the light resistance behind glass is very good, almost as good as acrylic.
Excellent chemical stability: Polyester fiber is resistant to acid, alkali and other chemical corrosion, and is not afraid of mold and insects.
Good wrinkle resistance and shape retention: Polyester fiber has high strength and elastic recovery ability, so it is durable, wrinkle-resistant and does not need ironing.
Good hygroscopicity: Polyester fiber has poor hygroscopicity and feels stuffy when worn. It is also prone to static electricity and dust contamination, affecting its appearance and comfort. However, because it dries easily after washing, has almost no drop in wet strength, does not deform, and has good washability and wearability.
Lighter texture: Polyester is less dense, so the fabric has a lighter weight.
Easy to process: Polyester fiber is easy to process into various shapes and sizes and is widely used in textiles, clothing, home decoration and other fields.
Good insulation: Polyester fiber has good insulation and does not conduct electricity easily, so it is often used in electrical and electronic equipment.
In general, polyester fiber is widely used in various fields due to its excellent properties and is one of the important raw materials in the textile industry.
