What is the difference between polypropylene thread and nylon thread?

1. The chemical molecular structure of the two is different
Nylon thread is a general term for thermoplastic resins containing repeating amide groups - [NHCO] - on the main chain of the molecule. The polypropylene thread is polypropylene fiber.

Haian County Xiaoxiao Thread Factory, located in the tenth group of Dulou Village, Duntou Town, Haian City, is a company specializing in the production and processing of polypropylene yarn, high-strength polyester yarn, nylon yarn and other products, and has a complete and scientific quality management system.

2. They have different uses
Nylon thread is often used to make combs, toothbrushes, clothes hooks, fan bones, mesh bag ropes, fruit outer packaging bags, etc. Non-toxic, but not long-term contact with acid and alkali. Polypropylene threads have both civil and industrial uses.

Civil use of polypropylene yarn: It can be spun purely or blended with wool, cotton or viscose to make various knitted goods such as socks, gloves, knitted sweaters, knitted trousers, dishcloths, mosquito nets, quilts, thermal fillers , wet diapers, etc.

Industrial use of polypropylene thread: carpets, fishing nets, canvas, hoses, concrete reinforcements, industrial fabrics, non-woven fabrics, etc. Such as carpets, industrial filter cloths, ropes, fishing nets, building reinforcements, oil-absorbing blankets and decorative Knitting Polyester Yarns.

3. The performance of the two is different
Nylon is a tough angular translucent or milky white crystalline resin. The molecular weight of nylon as an engineering plastic is generally 15,000-30,000. Nylon has high mechanical strength, high softening point, heat resistance, low friction coefficient, wear resistance, and self-lubrication. Nylon has a very good affinity with glass fiber. It is often used to make combs, toothbrushes, clothes hooks, fan bones, net bag ropes, fruit outer packaging bags, etc. Non-toxic, but not long-term contact with acid and alkali.
