How many types of polyester yarn are there?

In the textile industry, polyester fiber has attracted much attention due to its excellent properties and wide range of applications. As the world's largest producer of synthetic fibers, my country has always been at the forefront of the world in the production and research and development of polyester fibers. As one of its important finished products, polyester fiber yarn has diversified types to meet the needs of different fields.

At present, according to different classification standards, polyester yarn can be mainly divided into the following types:

According to different spinning processes, polyester hose yarn can be divided into traditional ring-spun polyester yarn and new polyester yarn. Traditional ring-spun polyester yarn refers to polyester yarn produced by traditional ring-spinning machines. It has a compact structure, smooth surface, and high strength, and is widely used in the manufacturing of various textiles and clothing. New polyester yarn refers to polyester yarn produced using new spinning technologies, such as compact spinning, air-end spinning, vortex spinning, etc. It has the characteristics of fluffy structure, light quality, softness and comfort, and is widely used in Home textiles, decoration and other fields.

According to different uses, polyester yarn can be divided into polyester  hose yarn for weaving and polyester yarn for knitting. Polyester yarn for weaving is mainly used to produce fabrics, which require high strength and good wear resistance; polyester yarn for knitting requires soft feel and good elasticity, and is suitable for the production of underwear, sportswear, etc.

Depending on the fineness, polyester yarn can be divided into coarse denier polyester yarn and fine denier polyester yarn. Coarse-denier polyester yarn has a larger diameter and a relatively stiff texture, and is suitable for producing heavy fabrics; fine-denier polyester yarn has a smaller diameter, soft and delicate texture, and is suitable for producing light and thin fabrics.

According to the different added ingredients, polyester yarn can be divided into pure polyester yarn and blended polyester yarn. Pure polyester yarn refers to yarn made of 100% polyester fiber; blended polyester yarn refers to yarn made of polyester fiber and other fiber blends, such as polyester-cotton blends, polyester-linen blends, etc. , with a variety of performance features.

With the continuous development of science and technology, the types of polyester yarns are still increasing. The application of new spinning technologies and advances in fiber modification technology provide more possibilities for the diversity of polyester yarns. For example, the development of functional polyester fiber makes polyester hose yarn possess antibacterial, anti-odor, anti-UV and other functions; while the addition of smart fiber gives polyester yarn the ability to sense and respond, which can be used in the manufacturing of smart textiles.

At the same time, as the concept of sustainable development becomes more and more popular, green environmental protection has become an important development direction of the textile industry. The development and application of bio-based polyester fibers provide strong support for the environmentally friendly performance of polyester yarns. Bio-based polyester fiber comes from renewable resources, such as corn, cassava, etc. Its production process is more environmentally friendly than traditional petroleum-based polyester, which helps reduce carbon emissions and resource consumption.

To sum up, polyester yarn has diverse types and a wide range of applications. Different types of polyester yarns have different performance characteristics and are suitable for different uses. With the continuous advancement of technology and changes in market demand, the types of polyester yarns will continue to be enriched and developed. In the future, as consumers have increasing demands for environmental protection, health and comfort, the development of polyester yarn will pay more attention to functionality, environmental protection and sustainability.
