The main physical and chemical properties of nylon


The main physical and chemical properties of nylon:


1. 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 nylon macromolecules will break;


2. Nylon has high strength, large elongation, and good elasticity, with a fracture strength of about 42-56cN/tex and a fracture elongation of 25% -65%. Therefore, nylon has good wear resistance and ranks first among common textile fibers. It is an ideal material for making wear-resistant wiping products. However, nylon has a small initial modulus, is prone to deformation, and its fabric is not stiff;


3. Moisture absorption and dyeing properties: Nylon has good moisture absorption among common synthetic fibers, with a moisture regain of about 4-5% under general atmospheric conditions; In addition, nylon has good dyeing properties and can be dyed with acid dyes, dispersed dyes, and other dyes;


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