There are obvious differences between PBT high-elastic yarn and polyester high-elastic yarn in many aspects.
1. Composition and structure: PBT high-elastic yarn belongs to polyester fibers, and its chemical structure is similar to that of polyester, but the carbon chain structure in the molecular chain is different, which makes PBT have higher elastic recovery performance.
2. Performance characteristics: PBT high-elastic yarn has excellent resilience, wrinkle resistance and shape retention, as well as high strength and wear resistance, which makes PBT high-elastic yarn widely used in clothing, home textiles and other fields. Polyester high-elastic yarn has high breaking strength and abrasion resistance, but poor wrinkle resistance and shape retention.
3. Processing method: PBT high-elastic yarn is usually produced by melt spinning, while polyester high-elastic yarn is produced by slice spinning.
4. Applications: PBT high-elastic yarn is mainly used to make high-end sportswear, high-end sofa fabrics, etc., while polyester high-elastic yarn is mainly used to make ordinary textiles and industrial supplies.
5. Environmental protection: PBT high-elastic yarn is biodegradable and environmentally friendly, while polyester is difficult to degrade, and long-term use will cause a certain burden to the environment.
In general, there are certain differences between PBT high-elastic yarn and polyester high-elastic yarn in terms of composition, performance characteristics, processing methods, application fields and environmental protection. Consumers can choose according to their needs and preferences when choosing.
