What kind of fabric is polyester fiber and its advantages and disadvantages?
Polyester fibre A synthetic fiber obtained by spinning a polyester obtained by polycondensation of an organic dibasic acid and a diol.
The polyester chain research report pointed out that the industrially mass-produced polyester fiber is made of polyethylene terephthalate, which is commonly known as polyester. It is the first large variety of synthetic fibers.
Let's take a look at what polyester fiber is.
The specific gravity of polyester is 1.38; the melting point is 255-260 ° C, the bonding starts at 205 ° C, the safe ironing temperature is 135 ° C; the moisture absorption is very low, only 0.4%; the breaking strength of the filament is 4.5 - 5.5 g / Dan, short fiber is 3.5 - 5.5 g / den; filament elongation at break is 15 - 25%, short fiber is 25 - 40%; high-strength fiber strength can reach 7 - 8 g / den The elongation is 7.5 - 12.5%.
Polyester has excellent wrinkle resistance, elasticity and dimensional stability, good electrical insulation properties, sunlight resistance, friction resistance, mildew resistance, good chemical resistance, and resistance to weak acids and weak bases. At room temperature, it has a certain ability to resist thin and strong acid, and has poor resistance to strong alkali. Polyester has poor dyeing properties and generally needs to be dyed with a disperse dye at high temperatures or in the presence of a carrier.
Polyester has many excellent textile properties and performance. It can be used in pure textiles, or blended with natural fibers such as cotton, wool, silk and hemp, and other chemical fibers. It is easy to dry, non-scaling and washable. It has good performance of wool, imitation cotton, imitation silk and imitation linen. Polyester fabric is suitable for men's and women's shirts, outerwear, children's clothing, upholstery fabrics and carpets. Polyester can also be used as cotton wool because of its good elasticity and bulkiness. In the industry, high-strength polyester can be used as tire cords, conveyor belts, fire hoses, cables, fishing nets, etc., and can also be used as electrical insulation materials, acid-resistant filter cloths, and paper-making blankets. Non-woven fabrics made of polyester can be used for interior decoration, carpet backing, pharmaceutical industry fabrics, flocking, lining, etc.
However, there are many obvious shortcomings in the fabric of this material. Now let's understand the shortcomings of polyester fiber.
Fibers are divided into natural fibers and man-made fibers. Polyester fibers are man-made fibers. Because they can be blended with other natural fibers, they are widely used in the garment industry. It is precisely because of this characteristic of polyester fiber that many people cannot distinguish it from natural fiber.
One of the shortcomings of polyester fiber is that it is poor in water absorption and airtight. When worn in summer, it feels very stuffy. This is mainly due to the low moisture content and poor gas permeability of polyester fibers compared with natural fibers. This is why we wear polyester fabrics in the summer, and we feel that after sweating, the clothes are attached to our skin, which is very uncomfortable.
The second disadvantage of polyester fiber is that it is easy to adsorb dust and generate static electricity. Winter wind and sand, it is conceivable that clothes wearing polyester fabric are easily contaminated with dust, which not only causes unsightly, but the most annoying is the static electricity generated, which not only feels stinging, but also if the pants are due to static electricity. Close to the skin, completely lose the pants type of pants, very unattractive.
The third disadvantage of polyester fiber: it is used by unscrupulous traders to produce high-grade fabrics. Polyester fiber is difficult to judge with the naked eye because of the feel and appearance and silk. It has been used by unscrupulous traders. In addition, many consumers do not understand that polyester fiber is the scientific name of polyester. It is misunderstood by the new name as a high-grade fabric, and some are considered to be silk derivatives, which makes it difficult for consumers to define the concept of silk and polyester fiber. .
