Polyester is a substantial variety of synthetic fiber.It is the commodity name of polyester fiber in our country.Polyethylene terephthalate (PET) is a fibrous polymer prepared from refined terephthalate (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or transesterification and condensation reaction and is made of the fiber after spinning and post-treatment. Polyester is a substantial variety of synthetic fiber.It is the commodity name of polyester fiber in our country.Polyethylene terephthalate (PET) is a fibrous polymer prepared from refined terephthalate (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or transesterification and condensation reaction and is made of the fiber after spinning and post-treatment.From the point of view of the molecular composition of polyester,it is composed of a short aliphatic hydrocarbon chain,ester group,benzene ring, and end alcohol hydroxyl group.  polyester fabric

There are no other polar groups except the two end alcohol hydroxyl groups in polyester,so the hydrophilicity of polyester fiber is very poor.The polyester molecule contains about 46% ester group,ester group in 200℃ above can hydrolyze,thermal cracking, in case of solid alkali soap,so that the polymerization degree is reduced,the ordinary amount of detergent washing powder below 100℃ does not affect polyester.Polyester characteristics: high strength,good elasticity,heat resistance,insulation, wear resistance, and corrosion resistance is relatively good, but dyeing and moisture absorption are relatively poor, but good color fastness and not easy to fade.Because there is no specific dyeing group on the polyester molecular chain, and the polarity is slight, it is challenging to dye; poor dyeing, dye molecules not easy to enter the fiber, Wear a sultry feeling, at the same time, easy to carry static electricity, stained dust, affect the appearance and comfort. However, it is easy to dry after washing, and the wet strength is almost not decreased, not deformed, and it has good washing and wearing performance.There are many kinds of polyester fiber fabric; in addition to weaving pure polyester fabric, there are many mixed or interwoven products with various textile fibers, which make up for the shortage of pure polyester fabric and play a better performance. Polyester fabric is developing towards the naturalization direction of synthetic fibers like wool, silk, hemp, and deerskin.

The superiority of the polyester-cotton blend

Comparison effect between poly-cotton blended fabric and pure cotton fabric: strength and extension (poly-cotton blended fabric > pure cotton); Wear resistance (poly-cotton blend > pure cotton); Pilling (poly-cotton blend < pure cotton), poly-cotton blend fabric is easy to pill, mainly because cotton fabric fiber strength is low, wear resistance is poor, the fabric surface formed wool ball or ball is quickly worn off; The chemical fiber and its blended fabric are easy to slip out of the surface of the material due to the small inter-fiber bonding force, high fiber strength, good elongation, excellent resistance to bending fatigue, torsional fatigue and wear resistance, once the formation of small balls on the surface is not easy to fall off quickly; Crease resistance (poly-cotton blend > pure cotton); Moisture permeability (poly-cotton blend < pure cotton); Air permeability (poly-cotton blend > pure cotton).

Poly-cotton "and" cotton polyester "changed the order of the two words into two different fabrics.

"Polyester cotton" (TC) fabric refers to a polyester composition of more than 50%, a cotton composition of less than 50%;

Advantages: gloss than pure cotton is bright, smooth, and crisp and is not easy to wrinkle, and the higher composition of polyester fabric is not easy to wrinkle.

Disadvantages: skin-friendly as cotton, wearing cotton fabric is not comfortable.

"Cotton/polyester" (CVC), on the contrary, refers to the composition of cotton above 50% and polyester below 50%, also known as CVC varieties.

Advantages: The gloss is slightly brighter than pure cotton cloth, and the cloth surface is smooth and clean without yarn head or impurities. Feel soft, crisp, wrinkle resistant than cotton.

Disadvantages: skin-friendly as cotton, wearing cotton fabric is not comfortable.

The superiority of polyester and linen blends

In the past, the yarn density of linen textiles was high, which could only be woven into medium and low-grade products. It was only suitable for making coats and decorative fabrics, which could not reflect the unique moisture absorption, good wetting, and incredible advantages of linen textiles. Polyester and flax fiber are now blended to produce high-grade flax series combined products suitable for summer interior and outerwear. What are the characteristics of polyester and linen blended fabric?

1.Cool to the touch

The Flax fiber blending ratio is 35%-40%, yarn appearance of flax fiber coverage is high, so when the human skin comes into contact with polyester./flax low particular yarn fabric, the heat on the human surface will be rapidly emitted, giving people an incredible feeling.

2.The fabric is light and brightly dyed

Yarn is fine, generally below 20tex (more than 50 male), and can be alone or with other textile fiber.Pure spinning or mixed yarn is interwoven into the ultra-thin fabric.This PRODUCT is of high grade, dyeing, printing bright, beautiful, and gorgeous; the material is famous for being excellent, transparent, thin, and calm.

3.Good wrinkle resistance

Because of the fiber characteristics, it can not only use the advantages of good anti-wrinkle of polyester fiber to improve the shortcomings of easy wrinkle and not bright dyeing but also use the advantages of good moisture absorption and moisturization of linen fiber to improve the shortcomings of poor moisture absorption and uncomfortable wearing of polyester fabric.

4.Comfortable to wear and good washability

Polyester linen yarn and fabric mixing proportion are moderate; the fabric feels soft, easy to wash, and easy to dry; the plastic shape is good, after washing deformation and pure linen fabric has good moisture absorption, wetting, air permeability, is a non-stick body high-grade summer inner coat fabric.

The superiority of polyester cashmere blend

Wool: polyester =45:55.This ratio can maintain the advantages of yarn and play the benefits of polyester.Almost all coarse and worsted wool fabrics have corresponding wool-polyester blends. Among them, worsted wool polyester thin tweed, also called calm and relaxed, commonly known as wool Dacron (note: Dacron is the common name of polyester), is one of the fabrics that can best reflect the characteristics of wool polyester blend.Compared with the whole wool tweed, the wool polyester thin tweed has a light and delicate texture, good crease recovery, strong wear-resisting, easy washing and quick drying, lasting pleat, regular size, not easy to moth, but not as soft as the natural wool.If polyester is used as raw material to blend, the cloth's surface has silky luster; if cashmere or camel wool and other species of animal hair are used in mixing raw material, the feel is smooth and tender.Washing instructions: soak in cold water for 15 minutes first, then wash with a general synthetic detergent. The temperature of the washing solution should not exceed 45 degrees Celsius. The dirty place of the collar and cuffs can be cleaned with a brush (soft).

The superiority of TR fabric

The polyester-viscose blend is a blend with substantial complementarity. Polyester viscose is not only cotton type, wool type, and long. Wool fabric is commonly known as "fast bus." When the polyester is not less than 50%, the blended fabric can maintain the firmness, wrinkle resistance, size stability, washability, and wear characteristics of polyester.Mixing viscose fiber improves the fabric's air permeability and anti-melting porosity. Reduce the pilling and anti-static phenomenon of fabric.

Polyester/viscose blend ratio of 65/35 or 67/33, this kind of blended fabric is characterized by smooth and smooth fabric, bright color, strong wool type, good hand elasticity, and good moisture absorption. But the iron resistance could be better.

Advantages of TR fabric:

1.High strength, short fiber strength of 2.6~5.7Cn/dtex, high strength fiber of 5.6~8.0Cn/dtex. Due to its low moisture absorption, its wet strength is the same as its dry strength, and its impact strength is four times higher than that of nylon and 20 times higher than that of viscose fiber.

2.Good elasticity, elasticity close to wool, when the elongation of 5%~6%, almost can be recovered entirely, wrinkle resistance more than other fibers, that is, the fabric does not wrinkle, good dimensional stability, elastic modulus of 22~141cN/dtex, 2~3 times higher than nylon.

3.Good water absorption.

4.Good wear resistance; wear resistance is second to the best wear resistance of nylon, better than other natural fibers and synthetic fibers.

5.Good light resistance, light resistance second only to acrylic.

6.corrosion resistance, can be resistant to bleach, oxidants, jing, ketone, petroleum products, and inorganic acids, resistant to dilute alkali, not afraid of mold, but hot alkali can make its decomposition.


The advantage of blended fabric is to meet people's different requirements for clothing through the organic combination of two or more different kinds of fibers, learning from each other and coexisting advantages. Blended fabric will combine the benefits of two or more types of raw materials to make up for each other to achieve better performance and comfort and significantly reduce the cost of the product. By introducing polyester and polyester blended fabric, we must have a further understanding of polyester.
