Polyester yarn, polyester yarn manufacturing process

Polyester silk, also known as polyester fiber, is a synthetic fiber made from polypropylene, amide, cellulose and other polymer compounds as raw materials. Polyester yarn has good elasticity and wear resistance, is not easy to deformation and aging, and is widely used.

Application areas of polyester yarn include:

1. Textile industry

Polyester silk is one of the important raw materials of textiles, which can be used to manufacture various home textiles, clothing and other textiles.

2. Construction Industry

Polyester filament can be used to reinforce concrete, improve the mechanical properties of concrete, improve the crack resistance of concrete, and improve the durability of concrete surface.

3. Printing

Polyester silk can be used to manufacture high-quality printing nets, which are widely used in the printing field of textiles, ceramics, glass, metal and other materials.

4. Health care

Polyester silk can be used to make medical bandages, surgical sutures and other medical supplies, with the characteristics of not easy to prick ji, not easy to cause allergies.

5. Industrial use

Polyester yarn can also be used to manufacture high-strength, high-elasticity industrial ropes, cables and other products, widely used in aerospace, ships, automobiles and other fields.

In summary, polyester yarn has a wide range of applications and excellent properties, is an important chemical fiber raw materials.

Polyester is a kind of synthetic fiber, light in texture, strong and durable, high gloss characteristics. Polyester is widely used in various fields, such as clothing, household goods, industrial products and so on.

1. Soft and comfortable

Polyester fabrics feel soft and comfortable, and there is no discomfort after wearing, as if the second skin. Therefore, it is very popular with consumers.

2. Easy to care for

Polyester silk is not only easy to clean, but also has good moisture absorption and can dry quickly. Therefore, housewives and enterprises are very fond of using textiles made of polyester silk.

3. It's cheap

Polyester silk is favored by a wide range of markets for its lower raw material costs and production costs, as well as good other properties. The price is affordable and loved by consumers.

4. Colorful

After thousands of years of history, people's feelings for color are still very rich. The dyeing performance of polyester silk is excellent, and various colors can be dyed to meet the needs of different consumers.

5. Go green

Polyester silk is a fully recyclable textile raw material, and will not pollute the environment during the production process, so it is more environmentally friendly. In the pursuit of sustainable development of modern people, polyester silk will have a broader application prospects.

In short, polyester silk is more and more recognized by consumers and enterprises because of its durable, soft, easy to care, affordable, diverse colors and environmental protection advantages, and its use will be more extensive in the future.

Polyester, also known as polyester fiber, is a synthetic fiber that has the advantages of toughness, high strength, and good tensile resistance. Its manufacturing process consists of the following steps:

Preparation of raw materials. The raw materials of polyester silk are polyethylene terephthalate and ethylene glycol. The two raw materials are mixed in a certain proportion and sent to a high-temperature and high-pressure reactor for polymerization.

The following reaction. Along reaction refers to the polyester that has been polymerized into small particles, and then remixed with the polyester reaction monomer, and then polymerized again by heating to expand the chain.

Spin a filament. The polymerized polyester particles are fed into the spinning machine, heated until melted, and drawn into fine threads by rotating the nozzle.

Stretch. The filaments are heated to a certain temperature and stretched using a stretching machine to make them stronger.

After processing or dyeing, polyester silk has become an important material for all kinds of clothing and fabrics.

In recent years, with the gradual improvement of social environmental awareness, more and more consumers have begun to pay attention to the environmental protection of textiles. Among them, polyester silk and cotton yarn are commonly used textile materials in People's Daily life. So, which is more environmentally friendly, polyester or cotton?

First of all, from the production process. The production of polyester silk requires the consumption of fossil fuels and produces certain pollution to the environment, while the production of cotton yarn requires a lot of water resources. Therefore, from this point of view, the two are equally environmentally friendly.

Secondly, from the use of the process. Polyester yarn has excellent durability and adhesion, can go through multiple washing without wear, pilling and other conditions, so compared with cotton yarn, polyester yarn is more durable, longer service life, reduce the pressure of consumers to buy frequently, save resources. The cotton yarn is easy to oxidize, rot, breed bacteria, etc., need to be replaced frequently, so compared with polyester silk, the environmental protection of cotton yarn is slightly lower.

In general, the degree of environmental protection of polyester silk and cotton yarn is similar, but polyester silk is more durable in the use process and more in line with the concept of modern sustainable development, so it is more recommended for consumers. Of course, when purchasing textiles, it is recommended to choose the brand certified by the environmental protection mark to control the environmental protection of textile materials and production process from the source.
