The difference between polyester fiber (polyester) and nylon (polyamide fiber, nylon) is mainly reflected in the advantages and disadvantages, uses, etc., as follows:
1, polyester fiber (polyester)
Advantages: polyester fiber is the biggest advantage of the wrinkle resistance and shape-retaining property is very good, with high strength and elasticity recovery ability. Have good electrical insulation properties, sunlight resistance, friction resistance, not mold and moth, have good resistance to chemical reagents, can resist weak acid and weak alkali. At room temperature, there is a certain degree of resistance to dilute strong acid ability, resistance to strong alkali is poor. It is firm and durable, wrinkle-resistant, non-ironing, non-sticky hair.
Disadvantages: polyester fiber and natural fibers compared to the existence of low water content, poor breathability, poor dyeing, easy to pilling hair, easy to stain and other shortcomings.
Use: polyester has many excellent textile properties and taking performance, a wide range of uses, can be pure textile manufacturing, but also with cotton, wool, silk, hemp and other natural fibers and other chemical fibers blending and interweaving, made of a wide variety of colors, firm and straight, easy to wash and easy to dry, free of ironing and wash wearable performance of good imitation of wool, imitation of cotton, imitation of silk, imitation of linen fabrics.
Polyester fabrics for men and women's shirts, outerwear, children's clothing, indoor decorative fabrics and carpets. Because polyester has good elasticity and fluffiness, it can also be used as wadding.
In industry, high-strength polyester can be used as tire cord, transport belt, fire hose, cable, fishing nets, etc., can also be used as electrical insulating materials, acid-resistant filter fabrics and paper blankets. Polyester nonwoven fabrics can be used for interior decorations, carpet backing, medical industry cloth, flannel, lining and so on.
2, polyamide fiber (polyamide)
Advantages: polyamide is mainly used for synthetic fibers, its most prominent advantage is that wear resistance is higher than all other fibers, 10 times higher than cotton abrasion resistance, 20 times higher than wool, a little bit of polyamide fibers in the blended fabrics, which can greatly improve its abrasion resistance; when stretched to 3-6%, elasticity of the recovery rate of up to 100%; to withstand tens of thousands of folding and flexing. Withstand tens of thousands of folding without breaking.
The strength of polyamide fiber is 1-2 times higher than cotton, 4-5 times higher than wool, and 3 times higher than viscose fiber.
Disadvantages: polyamide fiber heat resistance and light resistance is poor, the retention is also poor, made of clothing is not as strong as polyester.
Use: nylon products are widely used, is a plastic instead of steel, iron, copper and other metals, a good material, is an important engineering plastics; cast nylon is widely used in place of mechanical equipment, wear parts, instead of copper and alloy for the wear parts of the equipment. Applicable to the production of wear-resistant parts, transmission structure, household appliances parts, automotive parts, screw to prevent mechanical parts, chemical machinery parts, chemical equipment.
such as turbines, gears, bearings, impellers, cranks, instrument panels, drive shafts, valves, blades, screws, high pressure washers, screws, nuts, seals, bobbins, sets of simple, bushing connectors.
In addition, it can also be used to replace copper and other metals, for a variety of medical and knitted products.
