Polyester fiber sounds like a chemical substance. What exactly is polyester fiber? People who know it may know better. Polyester fiber fabrics are relatively common. Polyester fiber fabrics What are the advantages and disadvantages of polyester fiber? Let’s take a look at What is polyester fiber and the advantages and disadvantages of polyester fiber for your reference.

1. What is polyester fiber

Polyester fiber

Polyester fiber is a synthetic fiber made from petroleum. With the development of manufacturing technology, polyester has been developed and produced with a silky feel after alkali treatment and weight reduction processing. Fiber, and the mainstream products on the market today are ultra-fine fibers made using high-tech technology—new synthetic fibers. It refers to the general name for fibers made from polyester produced by polycondensation of various diols and aromatic dicarboxylic acids or their esters. What is polyester fiber? Polyester fiber is also called ice silk in the clothing industry.

What is polyester fiber? Polyester fiber has been widely used in the textile industry. At present, our country is also a big country in chemical fiber. However, how to make the fiber stronger requires enterprises to continuously improve own technology

Only with innovative capabilities and more added value can we go further. What is polyester fiber? Polyester fiber is mainly used for clothing and interior decoration. Short fibers can be spun purely or blended with natural fibers and other chemical fibers; filaments can be processed to make elastic yarns, tire cords, industrial ropes, transmission belts, filter cloths, fishing nets, etc., and can also be used as electrical insulation Materials and preparation of artificial blood vessels, etc.

2. Advantages and Disadvantages of Polyester Fiber Fabrics

1. Advantages of Polyester Fiber Fabrics

Advantages and disadvantages of polyester fiber fabric: Polyester fiber fabric is an ideal textile raw material. Its recovery ability (i.e. elasticity) from deformations such as elongation, compression, and bending is close to that of wool. , and because the fiber macromolecular chain has greater rigidity and high elastic modulus, the fiber is not easily deformed. The fabrics processed by it will not wrinkle after washing and do not need to be ironed. It has strong resistance to pesticides and is not prone to mildew and insect damage, so it is relatively simple to store. The pleats shaped by thermoplastic have high strength and good durability. The strength of polyester fiber is generally 44~71cN/dtex, which is 1 times higher than cotton and higher than wool.
3 times, it also has good heat resistance, light resistance and wear resistance, and can be used within -70~170℃.

Polyester sunshine fabric has flame retardant properties that other fabrics do not have. After burning, real polyester fabrics will retain the internal skeleton of glass fiber, so they will not deform, while ordinary fabrics will not have any residue after burning. Moisture proof. Bacteria cannot reproduce and the fabric will not become mildewed.

2. Disadvantages of polyester fiber fabrics

Advantages and disadvantages of polyester fiber fabrics: poor dyeing performance and moisture absorption performance , requires high temperature and high pressure dyeing, complex equipment, high cost, and static electricity is easily generated during processing. It is being solved through modification methods such as cocondensation with other components, eutectic spinning with other polymers, and spinning composite fibers or special-shaped fibers.

3. Polyester fiber fabric processing

(1) Alkali treatment to reduce volume

Advantages and disadvantages of polyester fiber fabrics: Polyester fiber will decompose after alkali treatment, and the surface of the fiber will dissolve and become thinner, resulting in a softer and more delicate feel. It is often used as a raw material for the manufacture of elegant ready-to-wear products such as women’s shirts.

Alkaline treatment to make the polyester fiber feel softer and softer. The texture structure becomes loose due to the thinning of the fiber. The arms can move up and down when wearing it. Repeated use will cause “texture twisting” in part of the fabric, the texture will become loose, and gaps will appear in some places, so product inspection is required. In addition, under the action of softener, the fibers will become slippery, making it easier for the phenomenon of “cloth twisting” to occur. In order to deal with the electrostatic characteristics of polyester products, soft processing is essential.

(2) Ultrafine fiber

This is the use of various A fiber with excellent softness and luster developed using high-tech science and technology. Products from Europe, the United States and other Asian countries have not yet reached the fiber level of Japan, but Japan leads the field with its advanced manufacturing technology in manufacturing polyester fibers called ultrafine fibers.

Generally, mixing black dye and red dye can highlight the depth of black, so in order to express the concentration of black, several colors are mixed in the dye. In this way, when the black material bleeds out, the remaining color will be emphasized. The fiber surface area of ​​ultrafine fiber products is larger. In order to achieve the ideal dyeing effect, more dye must be invested, so it is easier for uncolored dye to remain. Therefore, it is necessary to use post-processing beyond ordinary soaping.

The relationship between polyester fiber and polyester

First of all, we must determine the relationship between polyester fiber and polyester It is a kind of raw material, but why it has different names is because: polyester fiber is commonly used in the world.The number � is mainly famous for the earliest production name, and now it has become a common name in the world; polyester is the Chinese name, and polyester fiber in China is generally polyester. From this point of view it can be understood that there is no difference between them.

For those who do not understand polyester and polyester fiber, it is easy to be fooled by the name, thinking that the raw materials are different but they are fundamentally the same. For those who do not understand polyester, for those who understand polyester fiber You know, although polyester has a wide range of uses, it has certain shortcomings. Therefore, the names between the two can easily lead to misleading consumption. For this reason, we need to understand the advantages and disadvantages of polyester fiber and fully understand this material.

Polyester and polyester fibers are widely used and are mostly used in textiles. They can be blended with other raw materials to make various cotton-like, linen-like and silk-like fabrics. Ester fiber has the advantages of being easy to iron, easy to wash and dry, and can improve the shortcomings of other materials after blending. For example, it solves the problem that silk products are prone to wrinkles. Of course, the shortcomings of polyester fiber and polyester are that they are prone to pilling and have poor air permeability. However, modern technology is gradually improving these shortcomings through chemical modification.
