does polyester shrink,how to avoid

What is polyester fabric?

Polyester, an important variety of synthetic fibers, has a trade name called polyester fiber. It is a fiber-forming polymer made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or ester exchange and polycondensation reaction. Material - polyethylene terephthalate (PET).


Polyester fabric is a kind of chemical fiber clothing fabric used in daily life. Its biggest advantage is that it has good wrinkle resistance and shape retention, so it is suitable for outerwear. In our life, polyester fabric is a very common clothing fabric, which is widely used.


The advantages of polyester fabrics:

1. Polyester fabric has high strength and elastic recovery ability, so it is firm and durable, wrinkle-resistant and iron-free.

2. Polyester fabrics have poor hygroscopicity, feel sultry when wearing, and are easy to carry static electricity and stain dust, which affects the appearance and comfort. However, it is very easy to dry after washing, and the wet strength hardly decreases, and it does not deform. It has good wash and wear performance.

3. Polyester is the best heat-resistant fabric among synthetic fabrics. It has thermoplastic properties and can be made into pleated skirts with long-lasting pleats.

4. The light fastness of polyester fabric is better, except that it is worse than acrylic fiber, its light fastness is better than that of natural fiber fabric. Especially the light fastness behind the glass is very good, almost on par with acrylic.

5. Polyester fabrics have good resistance to various chemicals. Acids and alkalis are not very damaging to them, and they are not afraid of mold or insects.


Disadvantages of polyester fabrics:

1. Poor hygroscopicity. Polyester fabric has poor hygroscopicity, it will feel stuffy when wearing, easy to carry static electricity and be contaminated with dust, but it is very easy to dry after cleaning, the wet strength is almost unchanged, and it is not deformed, and the wearability is very good.

2. Poor dyeability. There is no specific dyeing gene, it is difficult to dye and easy to dye, but the color fastness after dyeing is very good, and it is not easy to fade.

3, easy to pilling. One of the synthetic fiber products, after a period of use, will pilling.

4. Poor melting resistance. It has poor melting resistance, and it is easy to form holes in case of sparks and soot. Avoid contact with cigarette butts and sparks when wearing.

Does polyester shrink in the dryer?


Polyester fabric is a chemical fiber fabric, which is not only durable, but also not easy to shrink because its synthetic fiber is shrink-resistant. Therefore, polyester fabrics are especially suitable for drying in a dryer.

Does 100 polyester shrink?

Polyester fabric, the washing temperature is between 0 and 40 degrees, and the dyeing temperature is around 140 degrees. It is a very stable material, and 100% polyester clothing will not shrink.


Polyester fabric does not shrink because it is determined by the characteristics of its raw material fibers. According to fiber chemistry, it is theoretically difficult for polyester to shrink because polyester is a fiber with poor hygroscopicity, that is, it is difficult for water molecules to enter the fiber.

Does 50 cotton 50 polyester shrink?


50% cotton 50% polyester fabric is also called polyester cotton (polycotton), which is what we call polyester-cotton (t/c) blended, or cotton-polyester (CVC) blended, this blended fabric will have a certain amount of Shrink, but not more than 3% by industry standards.


The reason for the shrinkage of 50% cotton and 50% polyester fabrics is mainly due to the fibers in the raw materials. Cotton fibers are natural fibers and will shrink in a certain amount when exposed to water. Polyester fibers are chemical fibers and will not shrink when exposed to water. The lower the shrinkage rate.

Does polyester and spandex shrink?

Polyester, also known as polyester, the full name of polyethylene terephthalate, is a synthetic fiber with the most extensive applications and the best fastness. The really good and polyester cards of the 1960s were its earliest forms. Polyester is characterized by good fastness, abrasion resistance, good color fastness and straight appearance.


Spandex, also known as Lycra, is made of polyurethane fiber throughout. Hong Kong people call it a pull frame, which is actually the pronunciation of Lycra. Spandex is characterized by very good elasticity and has the title of rubber fiber. Now all sportswear and pants must be added with spandex. The elasticity of pure spandex is so great that it has almost no shape, and it is what you wear. Therefore, in most cases, spandex cannot be used alone to make clothes, but can only be blended with polyester or nylon to provide moderate elasticity.


Polyester is a chemical synthetic fiber, and spandex is a polyurethane fiber, both of which have the property of not shrinking when exposed to water. Polyester-spandex composite fabric is also called polyester-spandex fabric, so polyester-spandex composite fabric also has the property of not shrinking when exposed to water.

does polyester shrink in cold water?

Polyester, also known as polyester, is a chemical synthetic fiber, because it is not hydrophilic, so no matter how it is washed in cold water, it will not shrink.
