The difference between nylon and polypropylene yarn

The difference between nylon and polypropylene yarn
1. Different uses of the two:
1, nylon yarn use: this kind of product is widely used, is a plastic replacement of steel, iron, copper and other metals good material, is an important engineering plastics; Cast nylon is widely used to replace wear-resistant parts of mechanical equipment, and to replace copper and alloy as wear-resistant parts of equipment. Suitable for making wear-resistant parts, transmission structure parts, household electrical parts, automobile manufacturing parts;
Lead screw to prevent mechanical parts, chemical machinery parts, chemical equipment. Such as turbine, gear, bearing, impeller, crank, instrument panel, drive shaft, valve, blade, screw, high pressure washer, screw, nut, sealing ring, shuttle, sleeve simple, bushing connector, etc.
2, polypropylene yarn (also known as pp yarn) use: pp yarn/polypropylene yarn woven into the ribbon and rope can be used for all kinds of luggage belt, travel bag, backpack, shoelaces, mobile phone sling and so on.
Two, the characteristics of the two are different:
1, the characteristics of nylon yarn: wear resistance is higher than all other fibers, 10 times higher than cotton wear resistance, 20 times higher than wool, slightly add some polyamide fiber in blended 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 bending without breaking.
2, the characteristics of polypropylene yarn: because polyamide has non-toxic, light weight, excellent mechanical strength, wear resistance and good corrosion resistance.
Three, the overview of the two is different:
1, nylon yarn overview: Dragon is the United States outstanding scientist Carothers (Carothers) and under the leadership of a scientific research team developed, is the world's first synthetic fiber, nylon is a polyamide fiber (nylon) of a statement. The appearance of nylon makes the textile a new look, its synthesis is a major breakthrough in the synthetic fiber industry, but also a very important milestone in polymer chemistry.
