Polyamide fiber, commonly known as nylon (), English name (abbreviation), density., is the general name for thermoplastic resins containing repeating amide groups [] on the molecular main chain. Including aliphatic, aliphatic aromatic and aromatic. Among them, aliphatic has many varieties, large output and wide application. Its name is determined by the specific number of carbon atoms of the synthetic monomer. It was invented by the famous American chemist Carothers and his scientific research team. Nylon is a term for polyamide fiber (nylon), which can be made into long fiber or short fiber.
Nylon is polycaprolactam, while nylon is polyhexamethylene adipamide. Nylon is % harder than nylon, and theoretically, the higher the hardness, the more brittle the fiber, and the easier it is to break. But this small difference is indistinguishable in carpet use.
Melting point and elasticity:
The melting point of nylon is ℃ and the melting point of nylon is ℃. But this is not a difference for the temperature conditions in which carpets are used. The lower melting point makes nylon have better resilience, fatigue resistance and thermal stability compared with nylon.
