Composition raw materials of sofa fabric


1. Composition of fabric:

Polyester fiber: synthetic fiber obtained by spinning polyester condensed from organic dibasic acid and dihydric alcohol, referred to as PET fiber, belongs to polymer compounds.

Polyester: Polyethylene terephthalate (PET), a fiber-forming polymer made from 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 polycondensation of diamine and diacid, and the other is obtained by polycondensation or ring-opening polymerization of caprolactam.

Cotton: woven from cotton yarn or blended yarn of cotton and cotton-type chemical fiber.

Spandex: Spandex is short for polyurethane fiber and is an elastic fiber.

2. Characteristics of fabric:

Polyester fiber: low moisture content, poor air permeability, poor dyeability, easy pilling and fuzzing, easy to stain and so on.

Polyester: high strength, high strength and elastic recovery, high heat resistance and thermal insulation, good thermoplasticity, good wear resistance, good light resistance, corrosion resistance, strong acid and alkali resistance, ultraviolet resistance, poor dyeability, good color fastness, fastness and good washability.

Nylon: The most outstanding advantage is that the wear resistance is higher than all other fibers, 10 times higher than cotton and 20 times higher than wool. Adding some polyamide fibers to the blended sofa fabric can greatly improve its wear resistance; When stretched to 3-6%, the elastic recovery rate can reach 100%; Can withstand tens of thousands of bends without breaking.

Cotton: Good moisture absorption and heat resistance, no peculiar smell, 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, sweat resistance, seawater resistance, dry cleaning resistance and wear resistance.

3. Use of fabric:

Polyester fiber: Polyester fiber has many excellent textile properties and wearability, and has a wide range of uses. It can be woven purely, or blended and interwoven with natural fibers such as cotton, wool, silk and hemp and other chemical fibers to make wool-like, cotton-like, silk-like and hemp-like fabrics with various colors, firmness and crispness, easy washing and drying, and good washability and wearability.

Because polyester has good elasticity and fluffiness, 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, etc., and can also be used as electrical insulation material, acid-resistant filter cloth and papermaking blanket.

Polyester: Polyester has a wide range of uses, and is widely used in making clothes and industrial products. Flame-retardant polyester has a wide range of applications because of its permanent flame retardancy. Besides playing an irreplaceable role in industrial textiles, interior decoration of buildings and interior decoration of vehicles, it also plays a lot of roles in the field of protective clothing.

Nylon: It is mainly used for synthetic fibers, and its most prominent advantage is that its wear resistance is higher than all other fibers. This kind of products has a wide range of uses. It is a good material to replace steel, iron, copper and other metals with plastics, and it is an important engineering plastic.

Cast nylon widely replaces wear-resistant parts of mechanical equipment, copper and alloy as wear-resistant parts of equipment. Suitable for making wear-resistant parts, transmission structural parts, household appliances parts, automobile manufacturing parts, screw rod prevention mechanical parts, chemical machinery parts and chemical equipment.

Used in all kinds of medical and knitwear. In civil use, it can be blended or spun into all kinds of medical and knitwear. Nylon filaments are mostly used in knitting and silk industry. In industry, nylon is widely used to make cord, industrial cloth, cables, conveyor belts, tents, fishing nets and so on. It is mainly used for parachutes and other military fabrics in national defense.

Cotton: fiber is used for textile and wadding. Various cotton fabrics made of cotton refer to sofa 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 ratio of spandex used in ordinary clothes is small. In North America, it is rarely used on men's clothes, but more used on women's clothes. Because women's clothes are required to be close to the body. When in use, a large amount of other fibers such as cotton and polyester blends are added to minimize the gloss.
