Nylon six and nylon six six fibers account for more than 95% of polyamide fibers. Their main properties are as shown in the table. Although their physical properties are different, in general use, their appearance, feel, strength and wear resistance are very close. , From its plain woven and knitted fabrics, it is also difficult to distinguish Xuan Yu, so they can often be replaced with each other, but if considering the cost, nylon six has the advantage.
The shrinkage rate of nylon six filaments is slightly higher than nylon six, which is more suitable for knitted fabrics and pile fabrics. Because nylon 6 has a lower softening point, it is softer than nylon six, but its curling deformation is more difficult, so nylon Sixty-six of the processed silk is superior to nylon six in the strength of shrinkage, so if it is used as a pantyhose material, nylon six six is more elastic than nylon six, and it is more durable.
The melting point of nylon six is higher than nylon six and the shrinkage rate can be lower. Therefore, the tire cord is more resistant to high-speed driving than nylon six after it is made into a tire. The tire can also travel a longer mileage. In addition, nylon six and six The melting point of polyester fiber is close to its cross fabric with polyester, which can be dyed at the same temperature as polyester, so the N/T fabric of nylon six or six (nylon and polyester cross fabric) is better than that of nylon six. Good fabric fastness.
