Different chemical molecular structure

Nylon thread is the general term for the thermoplastic resin with repeating amide group - [NHCO] - in the main chain of the molecule. Polypropylene yarn is polypropylene.

Different performance

Nylon is tough horny translucent or milky white crystalline resin, nylon as an engineering plastic molecular weight is generally 1.5-3 million. Nylon has high mechanical strength, high softening point, heat resistance, low coefficient of friction, abrasion resistance, self-lubricating, shock absorption and silencers, oil resistance, weak acid resistance, alkali resistance and general solvent, good electrical insulation, Self-extinguishing, non-toxic, odorless, good weather resistance, poor dyeing. Drawback is that water absorption, the impact of dimensional stability and electrical properties, fiber-reinforced resin can reduce water absorption, so that it can work under high temperature and humidity. Nylon and glass fiber affinity is very good. Commonly used in the production of combs, toothbrushes, hooks, fan, net bag rope, fruit bags and so on. Non-toxic, but not long-term and acid-base contact.

Polypropylene yarn straight vertical smooth, circular cross-section. The biggest advantage is the light texture, the density of only 0.91g / cm3, is the lightest varieties of common chemical fiber density. Polypropylene yarn has excellent elasticity and good abrasion resistance. In addition, the wet strength of polypropylene yarn is basically equal to dry strength, so it is the ideal material for making fishing nets and cables. The wicking ability is very strong and the effect of moisture absorption and perspiration is obvious. Polypropylene line dyeing is poor, incomplete chromatography, but the solution can be used to make up for the lack of coloring; polypropylene line has good chemical resistance, suitable for use as a filter material and packaging materials. In addition, polypropylene electrical insulation is good, but easy to produce static electricity during processing. Poor thermal stability, insensitive to the sun, easy to aging brittle damage, this is often joined in the anti-aging polypropylene; near the flame that is fused, flammable, away from the fire burning slowly and black smoke, the upper flame yellow, the lower blue , Exudes a smell of oil, after burning ash as hard yellowish brown particles, hand twist fragile.

Different uses

Nylon thread commonly used in the production of combs, toothbrushes, coat hooks, fan, net bag rope, fruit bags and other packaging. Non-toxic, but not long-term and acid-base contact.

Polypropylene yarn Civil use: Can be pure or blended with wool, cotton or viscose and other blended fabrics to make all kinds of knitwear such as hosiery, gloves, knitwear, knitted trousers, dishcloths, mosquito net cloth, batting, warm stuffing , Wet diapers and so on.

Polypropylene Thread Industrial Uses: Carpet, Fishing Net, Canvas, Hose, Reinforced Concrete, Industrial Fabrics, Nonwoven Fabrics. Such as carpet, industrial filter cloth, rope, fishing nets, building reinforcements, oil absorption carpet and decorative cloth.
