Information

Nylon is the trade name of polyamide fiber, also known as nylon. The focused structure of nylon is closely related to the stretching and heat treatment of the spinning process. Nylon twisted yarn is mainly filament, and there are a small amount of nylon staple fiber. Nylon twisted yarn is suitable for knitting and weaving, covering all areas of textiles.

The main physical and chemical properties of nylon (nylon yarn twisted) are reflected in the following aspects:

1. Form-The longitudinal surface of nylon is straight and smooth, and the cross section is round. Nylon is alkali-resistant and not acid-resistant. In inorganic acid, the amide bond on the nylon macromolecule will break.

2. Hygroscopicity and dyeability ——The hygroscopicity of nylon is better among common synthetic fibers, and the moisture regain rate is about 4.5% under general atmospheric conditions. In addition, nylon has good dyeability and can be dyed with acid dyes, disperse dyes and other dyes.

3. Strong elongation and abrasion resistance-Nylon has high strength, large elongation and excellent elasticity. The breaking strength is about 42~56cN/tex, and the breaking elongation is 25%~65%. Therefore, nylon has excellent abrasion resistance and ranks first among common textile fibers. It is an ideal material for making abrasive products. However, nylon has a small initial modulus, is easy to deform, and its fabric is not crisp.

4. Light resistance and heat resistance, etc.-because the end groups of nylon macromolecules are more sensitive to light and heat, which causes the nylon to turn yellow and become brittle, the light resistance and heat resistance of nylon are poor, so it is not suitable for making outdoor fabrics . In addition, nylon is resistant to corrosion, mildew, and insects.

The main purpose of nylon twisted yarn is to increase its strength and elasticity by adding twist to its filaments. With the miniaturization of automobiles, the higher performance of electrical and electronic equipment, and the acceleration of the lightweight of mechanical equipment, the demand for nylon will increase Higher and bigger. Especially nylon, as a structural material, puts forward high requirements on its strength, heat resistance, and cold resistance.
