Advantages and disadvantages of polyester fabrics
Dec 20, 2018

Polyester fabric is used in daily life is a very many chemical fiber clothing fabrics, its biggest advantage is wrinkle resistance and shape retention is very good, therefore, suitable for coat clothing, all kinds of bags and tents and other outdoor supplies.

Advantages of polyester fabrics:
First, polyester fabrics have high strength.Short fiber strength is 2.6 ~ 5.7cN/dtex, high strength fiber is 5.6 ~ 8.0cN/dtex, due to low moisture absorption, its wet strength and dry strength is basically the same, impact strength is 4 times higher than nylon, 20 times higher than viscose fiber.
Second, polyester fabrics are super elastic.Elasticity is close to wool, when the elongation of 5% ~ 6%, almost completely recovered, the polyester fabric repeatedly rubbed, and soon can be restored to its original shape, and no wrinkles, the elastic modulus of 22 ~ 141cN/dtex, than nylon 2 ~ 3 times higher than other fabrics, which can not be compared.
Thirdly, polyester fabrics have good heat resistance.It can be said that polyester has the best heat resistance and strong plasticity in chemical fiber fabrics. If it is made into pleated skirt, it can keep pleats well without excessive ironing.
Fourth, polyester fabrics light resistance is better.Polyester fabrics are generally made of goods are more resistant to the sun, the degree of natural fiber fabrics, polyester fabrics placed in the sun is basically no problem, do not worry about what side effects will occur.This feature makes polyester fabric light resistance and acrylic fabric is almost the same.
Fifth, polyester fabrics wear resistance is good.Wear resistance is second only to wear resistance of the best nylon, than other natural fibers and synthetic fibers are better.
Sixth, polyester fabrics have good chemical resistance.Polyester fabrics made of textiles, acid and alkali damage to its degree is not large, so some bleaching agent, oxidant on its fundamental effect, and polyester textiles are not afraid of mold, not afraid of moth.

Disadvantages of polyester fabrics:
First, poor dyeing.Because polyester molecular chain has no specific dye groups, and the polarity is small, and dyeing is more difficult, dyeability is poor, dye molecules are not easy to enter the fiber.But good color fastness, not easy to fade.
Second, poor melting resistance.Polyester is one of the most heat-resistant synthetic fabrics with thermoplastic properties. It can be used to make pleated skirts with long-lasting pleats.At the same time, polyester fabric has a poor resistance to melting, soot, Mars and other easy to form holes.Accordingly, when wearing, should avoid the contact such as cigarette end, spark as far as possible.
Third, poor moisture absorption.Polyester fabric hygroscopicity is poor, wearing a sultry feeling, at the same time easy to bring static electricity, dirt, affect the appearance and comfort.However, it is extremely easy to dry after washing, and the wet strength almost does not drop, does not deform, and has good washable and wearable properties.
Fourth, easy pilling.Polyester fabric is now a synthetic fiber products, all synthetic fiber fabrics will have pilling phenomenon!And polyester fabrics as a synthetic fiber of course is no exception, so polyester fabrics in a period of time after the use of pilling.
Polyester components:
Polyester is a synthetic fiber, it is based on refined terephthalic acid or terephthalic acid dimethyl ester and ethylene glycol (EG) as raw materials through esterification or ester exchange and condensation reaction of the fiber forming polymer - polyethylene terephthalate ester, after spinning and post-processing of fiber.It's also what we call dacron.
Polyester features:
1. High strength.The strength of short fibers was 2.6 ~ 5.7cN/dtex and that of high strength fibers was 5.6 ~ 8.0cN/dtex.Due to its low hygroscopicity, its wet and dry strength is basically the same.Impact strength is 4 times higher than nylon and 20 times higher than viscose fiber.
2. Good elasticity.The elasticity is similar to that of wool, and can be almost completely recovered at an elongation of 5-6%.Crease resistance is higher than other fibers, that is, the fabric does not crease, good dimensional stability.Elastic modulus is 22 ~ 141cN/dtex, 2 ~ 3 times higher than nylon..polyester fabric has high strength and elastic recovery ability, so it is firm and durable, wrinkle-resistant and non-ironing.
3. Heat-resistant polyester is made by melt spinning, and the formed fiber can be heated and melted again. It belongs to thermoplastic fiber.The melting point of polyester fiber is relatively high, and the specific heat capacity and heat conductivity are small, so the polyester fiber heat resistance and heat insulation is higher.It's the best synthetic fiber.
