Analysis of the advantages and disadvantages of polyester fabrics

What kind of fabric is polyester?

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. Therefore, it is suitable for Make outerwear, various types of bags, tents and other outdoor products.

Advantages and disadvantages of polyester fabrics:

Advantages of polyester fabrics:

First, polyester fabrics have high strength. The strength of short fiber is 2.6~5.7cN/dtex, and the strength of high-strength fiber is 5.6~8.0cN/dtex. Due to its low hygroscopicity, its wet strength and dry strength are basically the same. The impact strength is 4 times higher than that of nylon and 4 times higher than that of nylon. Viscose is 20 times taller.

Second, polyester fabric is super elastic. The elasticity is close to that of wool. When stretched by 5% to 6%, it can be almost completely restored. If the polyester fabric is rubbed repeatedly, it will quickly return to its original shape without leaving wrinkles. The elastic modulus is 22 to 141cN/dtex. Nylon is 2 to 3 times taller, which is unmatched by other fabrics.

Third, polyester fabric has good heat resistance. It can be said that polyester has good heat resistance and strong plasticity among chemical fiber fabrics. If it is made into a pleated skirt, it can maintain the pleats well and does not require excessive ironing.

Fourth, polyester fabrics have better light resistance. Items made of polyester fabrics are usually more light-resistant than natural fiber fabrics. It is basically no problem to expose polyester fabric items to the sun, and there is no need to worry about any side effects. This feature makes polyester fabrics almost as lightfast as acrylic fabrics.

Fifth, polyester fabric has good wear resistance. The wear resistance is second only to nylon with good wear resistance, and is better than other natural fibers and synthetic fibers.

Sixth, polyester fabrics have good chemical resistance. Textiles made of polyester fabrics are not greatly damaged by acids and alkalis, so some bleaches and oxidants have no effect on them at all, and polyester textiles are not afraid of mold or insects.

Polyester Disadvantages of fabrics:

First, poor dyeability. Because there are no specific dyeing groups on the polyester molecular chain and its polarity is small, it is difficult to dye and has poor dyeability. It is difficult for dye molecules to enter the fiber. But the color fastness is good and it is not easy to fade.

Second, poor melt resistance. Polyester is a fabric with the best heat resistance among synthetic fabrics. It is thermoplastic and can be made into pleated skirts with long-lasting pleats. At the same time, polyester fabric has poor melt resistance and can easily form holes when exposed to soot, sparks, etc. Therefore, when wearing it, you should try your best toAvoid contact with cigarette butts, sparks, etc.

Third, it has poor hygroscopicity. Polyester fabric has poor hygroscopicity and feels stuffy when worn. It is also easily charged with static electricity and contaminated with dust, affecting its appearance and comfort. However, it dries very easily after washing, has almost no drop in wet strength, does not deform, and has good washable and wearable properties.

Fourth, it is easy to pill. Polyester fabric is one of the current artificial synthetic fiber products. All synthetic fiber fabrics will have pilling! As a kind of artificial synthetic fiber, polyester fabric is of course no exception, so polyester fabric will be It will pill.

The biggest advantage of polyester fabric is that it is not easy to deform and wrinkle. It is more suitable for sofas, dining chairs and other places in the home. There is no need to worry about leaving wrinkles that will affect the aesthetic effect, so understand it before choosing textiles. It is necessary to know the characteristics of the fabric.
