Nylon fiber is a kind of synthetic fiber, its main component is polyamide. The molecular structure of nylon fiber has the following characteristics: 1. The molecule of nylon is composed of polyamide chain and substituent, and polyamide chain is its main structural unit. Polyamide chains are usually composed of aliphatic binary amines and dibasic acids, the most common of which are sulfite anhydride and caprolactam. A large number of amide groups (-Conh -) exist in the molecules of polyamide fiber, and these groups are connected by amide bonds
Nylon fiber is a kind of synthetic fiber, its main component is polyamide. The molecular structure of nylon fiber has the following characteristics:
1. The polyamide molecule is composed of polyamide chain and substituent, and polyamide chain is its main structural unit. Polyamide chains are usually composed of aliphatic binary amines and dibasic acids, the most common of which are sulfite anhydride and caprolactam. A large number of amide groups (-Conh -) exist in the molecules of polyamide fiber, and these groups are connected by amide bonds.
2, polyamide fiber molecules contain many methyl and methylene groups, these groups make polyamide molecules have good hydrophilicity, easy to stain.
3. The polyamide chain in the polyamide molecule is highly ordered, forming a certain crystalline region, so the polyamide fiber has excellent physical and mechanical properties, such as high strength and elasticity.
4, nylon fiber has good thermal stability and wear resistance, can maintain good physical properties at a higher temperature, not easy to wear.
The molecular structure of polyamide fiber is mainly composed of polyamide chain and substituent group, polyamide chain is its main structural unit. Due to the presence of more amide groups and methyl/methylene groups in its molecules, it has good hydrophilicity and easy staining.
Because nylon fiber has good physical and mechanical properties, heat resistance, wear resistance and easy staining and other advantages, it is widely used in various fields, some of the main application fields include:
1, textile field: can be used to produce a variety of fabrics and textiles, such as underwear, socks, sportswear, swimsuit, casual wear, work clothes, etc., its wear resistance and strength and other properties can make these textiles have good service life and comfort.
2. Industrial field: It is also widely used in the industrial field, such as manufacturing car seats, seat belts, tire cord, industrial ropes, filters and other products.
3, the field of packaging materials: can be used to produce a variety of packaging materials, such as high-strength fabric, fiberboard, gasket, etc., its high strength and wear resistance and other properties can protect the packaging items, making the packaging more durable.
4, home decoration field: can also be used to produce a variety of home decoration materials, such as carpet, sofa fabric, curtains, bedding, etc., its softness and wear resistance and other properties can make these home decoration materials more durable.
5, medical field: can be used in the production of medical supplies, such as surgical gowns, masks, drug filters, etc., its high strength and heat resistance and other properties can ensure the safety and service life of these medical supplies.
