Product Introduction
Polyamide (Nylon) is the first industrialized synthetic fiber, polymerized from petrochemical products such as caprolactam, hexamethylenediamine and adipic acid. It is wear-resistant, high-strength, elastic and lightweight, widely used in textiles, apparel, industry, automotive and other fields, and is a core category of high-performance synthetic fibers.
Types and Characteristics of Equipment
Type
Polyamide Synthetic Fiber: Mainly divided into PA6 and PA66 by raw material; divided into filament and staple fiber by form, suitable for textile and industrial scenarios, with core advantages of super wear resistance, high strength, high elasticity, lightweight and skin-friendly.
Features
Features Best wear resistance, 10 times that of cotton and 20 times that of wool, friction-resistant and long service life; High strength and lightweight, high tensile strength, density 1.14g/cm³, lighter than polyester; Excellent elasticity, good elongation recovery, resistant to repeated bending and not easy to deform; Good moisture absorption, second only to vinylon among synthetic fibers, comfortable to wear and easy to dye; Chemically resistant, alkali-resistant, oil-resistant and mold-proof, but the disadvantage is that it is not acid-resistant or sunlight-resistant.

Basic Principles and System Composition
Basic Working Principle
PA6 is obtained by ring-opening polymerization of petroleum-cracked caprolactam to form polyamide melt; PA66 is formed by polycondensation of hexamethylenediamine and adipic acid, both of which are made into fibers through melt spinning, drawing and setting.
