Polyamide (PA) is commonly known as nylon, with a density of 1.15g/cm3. It is a general term for thermoplastic resins containing repeated amide groups (NHCO) on the molecular backbone, including aliphatic PA, aliphatic aromatic PA and aromatic PA. Aliphatic PA has many varieties, large yield and wide application, and its name is determined by the specific number of carbon atoms of the synthetic monomer. It was invented by the famous American chemist Carothers and his research team.
Nylon is the United States outstanding scientist Carothers (Carothers) and his leadership of a scientific research team developed, is the world's first synthetic fiber.
The appearance of nylon makes textiles take on a new look. Its synthesis is a major breakthrough in synthetic fiber industry and a very important milestone in polymer chemistry.
The use of nylon fabric
Instead of metals like copper
Due to its non-toxic, light weight, excellent mechanical strength, wear resistance and good corrosion resistance, polyamide is widely used to replace copper and other metals in the manufacture of bearings, gears, pump blades and other parts in machinery, chemical industry, instrument, automobile and other industries. Polyamide fused into silk after high strength, mainly used as synthetic fibers and can be used as medical suture.
Used in all kinds of medical and knitwear
For civilian use, it can be blended or spun into a variety of medical and knitwear. Nylon filament is used for knitting and silk industry, such as woven single stockings, elastic stockings and other wear-resistant nylon socks, nylon gauze, mosquito net, nylon lace, elastic nylon outerwear, a variety of nylon or woven silk. Nylon short fiber is mostly used to blend with wool or other chemical fiber wool products to make a variety of wear-resistant clothing.
The advantages of nylon fabric
1, nylon fabric wear resistance in all kinds of fabrics, many times higher than other fibers, excellent durability.
2. The hygroscopicity of nylon fabric is also very good, and the clothes made of nylon are more comfortable than polyester clothes.
3, nylon fabric elasticity and recovery is very good, easy to deformation under external force, so easy to wrinkle in the process of wearing.
4, nylon fabric has self-extinguishing, non-toxic, odorless, good weather resistance, inert biological erosion, has good antibacterial, mildew resistance.
The disadvantages of nylon fabric
1, easy to static electricity
2, the sun and light resistance is very poor, in the wearing process must pay attention to the washing, maintenance conditions, so as not to damage the fabric
3, easy to aging
4, poor water absorption, poor dimensional stability.
Common problems of nylon fabric
1. Is the cleaning and antifouling of nylon fabric good
These two properties are affected by the shape of the fiber section and the antifouling treatment of the back channel. The strength and hardness of the fiber itself has little effect on cleaning and antifouling.
2. What is the melting point of nylon fabric? What kind of nylon fabric is used in the family
The melting point of nylon 6 is 220°c and the melting point of nylon 66 is 260°. For household low carbon, the temperature conditions of the melting point demand is not very high, so it is recommended to use better elastic nylon fabric 6.
3, the color fastness of nylon fabric
Color fastness is not a characteristic of nylon; it is the dye in the nylon, not the nylon itself, that fades when exposed to light.
