Nylon, also known as nylon, is a general term for polyamide fibers. It has high strength, wear resistance, and good resilience. Nylon has hygroscopicity and thermal setting properties, which can maintain the bending deformation formed during heating. Nylon filament (nylon) can be made into long or short fibers. Nylon filament is mostly used in knitting and silk industry; Nylon staple fibers are mostly blended with wool or woolen synthetic fibers.

The physical and chemical properties of nylon filament

Property 1: Form. The longitudinal surface of nylon is straight and smooth, with a circular cross-section. Nylon is alkali resistant but not acid resistant. In inorganic acids, the amide bonds on the nylon macromolecules will break.

Property 2: Strong elongation and wear resistance. Nylon has high strength, large elongation, and excellent elasticity. Its fracture strength is about 42-56cN/tex, and its elongation at break reaches 25-65%. So, nylon has excellent wear resistance. It is an ideal material for making wear-resistant friction products. But the initial modulus of nylon is small, easy to deform, and its fabric is not stiff.

Property three: hygroscopicity and staining. Nylon has better moisture absorption among common synthetic fibers, with a moisture regain of about 4.5% under normal atmospheric conditions. In addition, nylon has good dyeing properties and can be dyed with acid dyes, dispersed dyes, and other dyes.

Property 4: Light resistance and heat resistance, etc. Due to the sensitivity of the end groups of nylon macromolecules to light and heat, nylon turns yellow and brittle. Therefore, nylon has poor light and heat resistance and is not suitable for making outdoor fabrics. In addition, nylon is corrosion-resistant, not afraid of mold, and not afraid of insect infestation.
