Classic Polyester Yarn: Innovations and Expanding Horizons

Classic Polyester Yarn, or traditional polyester yarn, is a widely used synthetic fiber material. Since its birth, it has become an indispensable part of the textile industry with its unique properties and diverse application fields. With the advancement of science and technology and changes in market demand, polyester yarn has not only continued to innovate in technology, but also demonstrated great potential in market expansion.

Polyester yarn is made of polyethylene terephthalate (PET) through a specific spinning process and has properties such as high strength, wear resistance, wrinkle resistance, easy washing and quick drying. These properties make polyester yarn an ideal choice for manufacturing clothing and industrial products. Especially in the field of flame-retardant polyester, through special chemical treatment, polyester yarn has acquired permanent flame retardancy, which makes it not only widely used in industrial textiles, building interior decoration and vehicle interior decoration, but also plays an important role in the field of protective clothing. According to the national standard for flame-retardant protective clothing, metallurgy, forestry, chemical industry, petroleum, fire protection and other departments should use flame-retardant protective clothing. The number of people in China who should use flame-retardant protective clothing is more than one million. This market demand has further promoted the research and development and production of flame-retardant polyester yarn.

In the production process of polyester yarn, technological innovation plays a vital role. Traditional polyester yarn is usually dyed with disperse dyes under high temperature and high pressure. In recent years, the emergence of cationic polyester yarn (Cationic Polyester Yarn, referred to as CD yarn) has brought revolutionary changes to the dyeing process.

Cationic polyester yarn uses cationic dyes and can be dyed at room temperature and pressure, which not only simplifies the dyeing process, but also reduces energy consumption and improves production efficiency. This innovation not only improves the dyeing performance of polyester yarn, but also opens up a new path for its environmentally friendly production.

As an important branch of polyester yarn, the development of polyester industrial yarn production technology is also remarkable. The research and development of polyester industrial yarn melt direct spinning technology has achieved continuous production from raw materials to finished products, eliminating cooling and pelletizing, solid phase polycondensation, melt extrusion and other processes, making the process more compact and significantly improving production efficiency. This technology not only reduces production energy consumption and operating costs, but also improves product quality to meet the national standard GB/T16604-2008. The widespread application of polyester industrial yarn melt direct spinning technology marks that polyester industrial yarn production has entered a new stage of development and provides strong technical support for the diversified application of polyester yarn.
