Classic Polyester Yarn: The Staple of Modern Textile Industry

In the modern textile industry, Classic Polyester Yarn, as a synthetic fiber, occupies a pivotal position. Polyester, also known as polyester fiber, has become an important pillar of the global textile industry with its physical and chemical properties.

Polyester yarn is made of polyester resin as the main raw material, and the fiber is made through polymerization, spinning, stretching and other processes, and then spun. Polyester fiber is widely used in the manufacture of various textiles due to its wear resistance, fading resistance, wrinkle resistance, easy washing and easy drying. Polyester yarn not only has high strength and low elongation, but also has good thermal stability and dimensional stability, which makes it have performance in many fields.

According to different structures and uses, polyester yarn can be divided into many types. Ordinary standard polyester industrial yarn, also known as high-strength low-stretch polyester industrial yarn, is mainly used for high-strength products such as tire cord, conveyor belts and automotive seat belts. High modulus low shrinkage polyester industrial yarn has gradually replaced ordinary standard polyester industrial yarn in tires and mechanical rubber products due to its high breaking strength, high elastic modulus and low elongation. High strength low shrinkage polyester industrial yarn is widely used in coated fabrics and conveyor belt wefts due to its small shrinkage after heating. Special functional polyester industrial yarns, such as seawater repellent, flame retardant, and wear-resistant, have further expanded the application range of polyester yarn.

In the field of textile fabrics, polyester yarn also plays an important role. Clothing made of polyester fabrics is not only wear-resistant and wrinkle-resistant, but also has good elasticity and recovery, which makes polyester an ideal choice for making high-end knitwear, sportswear and outdoor clothing. The easy-drying characteristics of polyester fiber also make it popular in the production of bedding and towel products, which can absorb and evaporate moisture faster and maintain comfort.

Another major advantage of polyester yarn is its economy. Compared with natural fibers such as cotton, linen and wool, polyester has a short production cycle, abundant raw materials, and a more efficient production process. This not only reduces production costs, but also makes polyester yarn and its products competitive in price. Especially in the process of the global textile industry shifting from developed countries to developing countries, the widespread use of polyester yarn has greatly promoted the development of labor-intensive industries, absorbed a large number of surplus labor, and promoted the integration of the global economy.

The environmental protection of polyester yarn is also an advantage that cannot be ignored. Although the production process of traditional polyester may cause certain environmental pollution, with the advancement of technology, recyclable and biodegradable polyester fibers have gradually been developed. These new polyester yarns not only maintain the performance of traditional polyester, but also reduce the negative impact on the environment, which is in line with the concept of modern green production.
