Polyester fiber: synthetic fiber spun from polyester condensed from organic dibasic acid and diol, referred to as PET fiber, belongs to polymer compounds.
Polyester: Polyethylene terephthalate (PET), a fiber-forming polymer made of polyethylene terephthalate (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG), is spun and post-treated.
Nylon: commonly known as nylon, it can be divided into two categories: one is poly (hexamethylene adipate) obtained by condensation polymerization of diamine and dibasic acid, and the other is obtained by condensation polymerization or ring-opening polymerization of caprolactam.
Cotton: woven from cotton yarn or blended yarn of cotton and cotton-based chemical fiber.
Spandex: Spandex is short for polyurethane fiber and is an elastic fiber.
2. Features:
Polyester fiber: low moisture content, poor air permeability, poor dyeability, easy pilling, easy to stain and so on.
Polyester: high strength, high strength and elastic recovery, high heat resistance and heat preservation, good thermoplasticity, good wear resistance, good light resistance, corrosion resistance, strong acid and alkali resistance, ultraviolet resistance, poor dyeability, good color fastness and good washing resistance.
Nylon: The most outstanding advantage is that its wear resistance is higher than all other fibers, which is 10 times higher than cotton and 20 times higher than wool. Adding some polyamide fibers to blended fabric can greatly improve its wear resistance. When stretched to 3-6%, the elastic recovery rate can reach100%; Can withstand tens of thousands of bends without breaking.
Cotton: good hygroscopicity and heat resistance, no odor, alkali resistance and warmth retention.
Spandex: Spandex has excellent elasticity. The strength is 2 ~ 3 times higher than that of latex yarn, the linear density is thinner and it is more resistant to chemical degradation. Spandex has good acid and alkali resistance, perspiration resistance, seawater resistance, dry cleaning resistance and wear resistance.
Step 3 use:
Polyester fiber: Polyester fiber has many excellent textile properties and wearability, and is widely used. It can be woven pure, blended and interwoven with natural fibers such as cotton, wool, silk, hemp and other chemical fibers to make wool-like, cotton-like, silk-like and hemp-like fabrics with various colors, which are firm and crisp, easy to wash and dry, and have good washing resistance and wear resistance.
Because polyester has good elasticity and bulkiness, it can also be used as wadding cotton. In industry, high-strength polyester can be used as tire cord, conveyor belt, fire hose, cable, fishing net and so on. It can also be used as electrical insulation material, acid-resistant filter cloth and paper-making blanket.
Polyester: Polyester is widely used in making clothes and industrial products. Flame-retardant polyester is widely used because of its long-lasting flame retardancy. In addition to playing an irreplaceable role in industrial textiles, building interiors and vehicle interiors, it has also played a lot of roles in the field of protective clothing.
Nylon: mainly used for synthetic fibers, the most prominent advantage is that the wear resistance is higher than all other fibers. This product has a wide range of uses. It is a good material to replace steel, iron, copper and other metals with plastic, and it is an important engineering plastic.
Cast nylon widely replaces the wear-resistant parts of mechanical equipment, and copper and alloy are used as the wear-resistant parts of equipment. It is suitable for manufacturing wear-resistant parts, transmission structural parts, household electrical appliances, automobile manufacturing parts, anti-screw mechanical parts, chemical mechanical parts and chemical equipment.
Used in all kinds of medical care and knitwear. In civil use, it can be blended or spun into various medical and knitwear. Nylon yarn is mainly used in knitting and silk industry. In industry, nylon is widely used to make ropes, industrial cloth, cables, conveyor belts, tents, fishing nets and so on. Mainly used in military fabrics such as parachutes in the field of national defense.
Cotton: Fibers are used for textiles and fillers. Various cotton fabrics made of cotton refer to fabrics made of cotton yarn or blended yarn of cotton and cotton chemical fiber.
Spandex: It can be used for clothes that can be stretched to meet comfort requirements. The proportion of spandex used in ordinary clothes is very small. In North America, it is rarely used in men's wear, but more used in women's wear. Because women's clothing requires close fitting. When in use, a large number of other fibers, such as cotton and polyester blends, are added to minimize the gloss.
