Which industries will use more polyester fibers
source：www.03559659.cn | Release time：2025-08-061. Textile and clothing industry: Polyester fiber is an important textile raw material with characteristics such as high strength, high modulus, and low water absorption. Polyester short fibers can be spun pure or blended with natural fibers such as cotton, linen, wool, or other chemical short fibers to produce various cotton, wool, and medium to long fiber textiles. Polyester filament can be used for machine weaving, knitting and other processing, applied in the fields of clothing fabrics, decorative fabrics and non-woven fabrics, such as making shirts, sportswear, curtains, sofa fabrics, etc.
2. Transportation industry: Polyester fiber is widely used in the transportation industry, with direct applications such as seat cushions, seat belts, carpets, etc; Indirect applications include composite materials such as inflatable hulls, tire cords, airbags, interior decorative fabrics, etc. 90% of global car seat fabrics use polyester fibers, and the amount of polyester industrial yarn used in airbags is about 30%. HMLS polyester industrial yarn has also become the main reinforcing material for the carcass of semi steel radial tires.
3. Industrial manufacturing industry: Polyester fiber strong yarn is widely used in the manufacturing of industrial ropes, conveyor belts, filter fabrics, etc. due to its high strength and modulus, excellent high temperature resistance, fatigue resistance, and stability. In addition, polyester fiber is also a good filling material and insulation material, which can be used for papermaking fabrics, sewing threads, etc. It can also be made into products with special properties such as water repellency, anti-static, and flame retardancy.
4. Construction industry: Polyester fibers can be used in the fields of construction and building materials, such as insulation materials, roof waterproofing materials, wall coatings, flooring materials, and insulation materials. The weather resistance, chemical resistance, and insulation properties of polyester fibers make them the preferred choice for building materials. In addition, polyester engineering fibers can also be used in scenarios such as concrete reinforcement and roadbed reinforcement.
5. Packaging industry: Polyester bottle flakes are widely used in packaging of food, beverages, cosmetics, pharmaceuticals and other fields due to their excellent material properties. By 2025, the global demand for food grade PET has exceeded 35 million tons, and 80% of new projects in Nantong, Ningbo, and other places have locked in the bottle chip field, accurately matching emerging demands such as beverage packaging.6. Medical industry: PES fiber (polyethersulfone fiber) is used to produce high value-added products such as sutures and artificial blood vessels due to its biocompatibility and antibacterial properties. Antibacterial fibers can also be used to make medical dressings, and the market size is expected to reach 1.2 billion US dollars by 2025.
