Polyester filament is a synthetic fiber with excellent wear resistance, corrosion resistance and wrinkle resistance. It is widely used in textiles, industrial threads and knitwear and other fields. The specifications and product science of polyester filament yarns are as follows:
1. Specification: The specification of polyester filament is usually expressed by the "D" value, that is, the mass per unit length. Common specifications include 75D, 100D, 150D, 300D, etc., where the larger the "D" value, the greater the thickness of the fiber.
2. Product categories: There are many types of polyester filament products, including ordinary polyester filament, high elastic polyester filament, ultra-fine polyester filament, etc. Ordinary polyester filaments are mainly used in textiles and industrial threads, high-elastic polyester filaments are mainly used in elastic fabrics and sportswear, and ultra-fine polyester filaments are mainly used in light and thin fabrics and high-end clothing.
3. Characteristics: Polyester filament has excellent wear resistance, corrosion resistance and wrinkle resistance, as well as soft, smooth and easy to clean. It also has good heat resistance and chemical resistance, suitable for various production process requirements.
In a word, polyester filament is a kind of high-quality synthetic fiber, which has a wide range of application prospects and can meet the needs of different fields.
