Textile products: polyester material

Polyester is an important variety of synthetic fiber and the trade name of polyester fiber in China. Polyethylene terephthalate (PET) is a kind of fiber polymer, which is made from PTA, DMT and MEG by esterification, transesterification and polycondensation. It is spun and treated.

Molecular structure formula, as shown in the figure:

From the molecular composition of polyester, it is composed of short aliphatic chain, ester group, benzene ring and alcohol terminated hydroxyl group. In addition to the existence of two alcohol terminated hydroxyl groups, there are no other polar groups in polyester fiber, so the hydrophilicity of polyester fiber is very poor. Polyester molecule contains about 46% ester group, which can be hydrolyzed and pyrolyzed when temperature is above 200 ℃, and it can be soaped when it meets strong alkali, so the degree of polymerization is reduced. Detergent washing powder with normal dosage below 100 ℃ has no effect on polyester.

Polyester features: high strength, good elasticity, heat resistance, heat insulation, wear resistance, corrosion resistance are relatively good, but the dyeing and moisture absorption are relatively poor, but the color fastness is good, not easy to fade.

There are many kinds of polyester fabrics. In addition to pure polyester fabrics, there are many products mixed or interwoven with various textile fibers, which make up for the shortage of pure polyester fabrics and play a better wearing performance. Polyester fabric is developing in the direction of natural synthetic fibers such as wool like, silk like, hemp like and deer skin like.

Advantages of polyester cotton blend

The contrast effect between T / C blended fabric and pure cotton fabric: strength and elongation (T / C blended fabric > pure cotton); wear resistance (T / C blended fabric > pure cotton); pilling and pilling (T / C blended fabric < pure cotton), which is easy to pilling, mainly because of the low strength and poor wear resistance of cotton fabric, the wool balls or pellets formed on the surface of the fabric are quickly worn off; and chemical fiber and its blended fabric are due to the fiber It has small dimensional cohesion, high fiber strength and good elongation, especially good bending fatigue resistance, torsion fatigue resistance and wear resistance, so the fiber is easy to slide out of the fabric surface, and it is not easy to fall off quickly once a small ball is formed on the surface; crease resistance (T / C blend > pure cotton); moisture permeability (T / C blend < pure cotton); air permeability (T / C blend > pure cotton).

Polyester cotton "and" cotton polyester ", the order of the two words changed into two different fabrics.

"Polyester cotton" (TC) fabric refers to the polyester component accounting for more than 50%, and the cotton component is less than 50%;

Advantages: the luster is brighter than pure cotton cloth, the feel is smooth, crisp, and not easy to wrinkle, and the higher the composition of polyester, the less likely the fabric is to wrinkle.

Disadvantages: skin affinity is not as good as cotton, wearing no cotton fabric comfortable.

"Cotton polyester" (CVC) is the opposite, which means that the composition of cotton is more than 50%, and that of polyester is less than 50%, also known as CVC variety.

Advantages: the luster is slightly brighter than pure cotton, the cloth surface is flat, clean and free of gauze head or impurities. It feels smooth, crisp and wrinkle resistant.

Disadvantages: skin affinity is not as good as cotton, wearing no cotton fabric comfortable.

Advantages of polyester flax blend

1. Cool touch

The flax fiber blending ratio is 35% - 40%, and the flax fiber coverage rate of the yarn appearance is high. Therefore, when the human skin contacts the polyester / hemp low tex fabric, the heat on the human body surface will be quickly emitted, so that people have a cool feeling.

2. The fabric is light and bright colored

The yarn is thin, generally under 20tex (more than 50g), and can be interwoven into ultra-thin fabric by itself or with pure or blended yarn of other textile fibers. The product is of high grade, bright and beautiful in dyeing and printing, and the fabric is famous for its cool, transparent, thin and cool.

3. Good crease resistance

Due to the fiber characteristics, the advantages of polyester wrinkle resistance can be used to improve the wrinkle and dyeing of linen fabric, and the advantages of linen moisture absorption and dehumidification can be used to improve the poor moisture absorption and uncomfortable wearing of polyester fabric.

4. Comfortable to wear, good washability

The blending ratio of polyester flax yarn and fabric is moderate, the fabric feels soft, easy to wash, easy to dry, and has good plastic setting. After washing, it does not deform and has the same good moisture absorption, moisture release and air permeability as pure flax fabric. It is a high-grade summer inner and outer clothing fabric that does not stick to the body.

Polyester viscose blend is a kind of blend with strong complementarity. There are not only cotton type, wool type, but also medium length type. Wool fabric is commonly known as "Kuaiba". When the polyester content is not less than 50%, this kind of blended fabric can keep the strong, wrinkle resistant, size stable, washable and wearable characteristics of polyester. The mixing of viscose fiber improves the permeability of fabric, improves the resistance to melting hole, reduces the pilling and antistatic of fabric.

The ratio of polyester / viscose blend is 65 / 35 or 67 / 33. The characteristics of this kind of blended fabric are smooth, bright color, strong wool shape, good flexibility and moisture absorption, but poor ironing resistance.

The advantage of blended fabric is that through the organic combination of two or more different kinds of fibers, it can learn from each other's strengths and complement each other's weaknesses, coexist its strengths, and meet people's different requirements for clothing. The blended fabric will combine the advantages of two or more materials to make up for each other, so as to achieve better performance and comfort of the fabric, and also greatly reduce the cost of the product. Through the introduction of polyester and polyester blended fabric, we must know more about polyester and polyester.
