The role of polyester processed parts is mainly reflected in many fields and aspects, including applications in industry, agriculture, new technology fields, packaging industry, electronics, health care, construction, automobiles and other fields. Polyester fiber and polyester resin are the two main categories of polyester processed parts, and they each play an important role in specific fields.
Polyester fiber has a wide range of applications, including textile industry, ropes, carpets and other consumer products. When combined with cotton, polyester fiber can produce fabrics that will not shrink or wrinkle, and its strength and flexibility make it more tear-resistant. In addition, polyester textiles are widely used in automotive interiors, and PET has become an ideal packaging material due to its non-reactive properties with many foods. Post-processing of polyester fibers improves the structure of the fiber and gives it excellent performance, such as stretching, heat treatment, etc., to further improve the strength and performance of the fiber.
Polyester resin is mainly used in three major fields: fiber, sheet, film and bottle resin. About half of the world's synthetic fibers are made of PET, which is suitable for the production of high-strength fibers, papermaking nets, high-strength films, etc. Polyester resins are also used in bottles, films, etc., and are widely used in the packaging industry. It is the largest non-fiber application market for polyester and also the fastest growing field for PET. As an important intermediate product connecting petrochemical products and products from multiple industries, the wide range of applications of polyester chips shows the important role of polyester processed parts in multiple industries.
In summary, polyester processed parts have not only improved the performance and quality of products through their application in multiple fields such as textiles, packaging, and building materials, but also promoted the development and progress of related industries12.
