It's worth taking a look at the physical and chemical properties of nylon twisted yarn!

Release time:

Aug 22,2020

Nylon is the trade name for polyamide fibers, also known as nylon. The focused state structure of nylon is closely related to the stretching and heat treatment during the spinning process. Nylon twisted yarn is mainly made of long fibers, and there are also a small amount of nylon short fibers. Nylon twisted yarn is suitable for knitting and weaving, covering all fields of textiles.

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

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 nylon macromolecules will break.

2. Moisture absorption and dyeing properties - Nylon has the best moisture absorption among common synthetic fibers, with a moisture regain of around 4.5% under general atmospheric conditions. In addition, nylon also has good dyeing properties, which can be dyed with acid dyes, disperse dyes, and other dyes.

3. Strength, 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%. Therefore, the wear resistance of nylon is particularly excellent, ranking first among common textile fibers. 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 straight.

4. Light resistance and heat resistance - Due to the sensitivity of the end groups of nylon macromolecules to light and heat, resulting in yellowing and brittleness of nylon, its light resistance and heat resistance are poor, and it is not suitable for making outdoor fabrics. In addition, nylon is corrosion-resistant, not afraid of mold and insects.

Nylon twisted yarn is mainly aimed at increasing its strength and elasticity by adding twist to its filament. With the miniaturization of automobiles, the high-performance of electronic and electrical equipment, and the acceleration of lightweight mechanical equipment, the demand for nylon will be higher and greater. Especially as a structural material, nylon has high requirements for its strength, heat resistance, and cold resistance.

What are the benefits of nylon reflected in?

Polyamide, also known as nylon silk, is mainly used for synthetic fibers. Its most prominent advantage is that its wear resistance is higher than all other fibers, 10 times higher than cotton and 20 times higher than wool. Adding some polyamide fibers to blended fabrics can greatly improve their wear resistance; When stretched to 3-6%, the elastic recovery rate can reach 100%; Can withstand tens of thousands of twists and turns without breaking.

Don't believe it! Look!! The effect of using nylon silk fabric is really different~

Nylon can maintain the bending deformation formed during heating. Its long filaments can be made into elastic filaments, while its short filaments can be blended with cotton and acrylic fibers to improve their strength and elasticity. In addition to being used in underwear and decorations, it is also widely used in industrial fields such as cord threads, transmission belts, hoses, ropes, fishing nets, tires, parachutes, etc. Its wear resistance is 10 times that of cotton fiber, 10 times that of dry viscose fiber, and 140 times that of wet fiber, making it extremely durable.

How does the nylon industry shoulder the burden of fashion

China is a major producer of nylon civilian fibers, and the future development space is still very broad. However, compared to its position as a major producer of nylon, China's nylon industry still urgently needs to enhance its strength in areas such as product application development, brand expansion, and cultural construction. The era of nylon industry expansion relying on scale and quantity has come to an end, and changes in labor and other related factors have led the industry into a new era that requires changes in development methods, structural adjustments, and transformation and upgrading. It needs to rely on technology, culture, brand, and innovation to drive the overall upgrading of the industrial chain value.

Chemical fiber industry: This year's "Golden Nine" has not risen as much as in previous years

In July and August of this year, polyester filament manufacturers generally gained a lot. Due to tight supply, FDY products have a high profit level per ton. DTY and POY products have relatively weak returns. DTY products benefit from the lag in price changes, and their profit level decreases slowly during the period of POY price decline. Although POY began to turn losses into profits in early July, it fell to the edge of profit and loss in mid to late September.
