What is Nylon(PA)/nylon NYLON(N) or spandex(PU)
Apr 26, 2018

What is Nylon(PA)/nylon NYLON(N) or spandex(PU)?

Nylon (PA) or Nylon NYLON (N):

1, the strength is very good, even more than the same fineness of the wire.

2, wear resistance is very good, more than other textile fibers, suitable for sportswear, socks, parachutes, cables.

3, poor water absorption, a fixed moisture regain of 4%, easy static electricity, fluffing, pilling.

4, alkali is not acid, 37.5% hydrochloric acid can be dissolved.

5, good corrosion resistance, poor water resistance, poor light resistance, heat resistance, long-term drying power decreased yellowing.

6, nylon garments easily deformed, easy to wrinkle.

Spinning form: Main FDY, ATY.

Spandex (PU):

Properties: 500-800% extensible, low strength, good resistance to perspiration, seawater, acid and alkali resistance. It can not be used alone for latitude and longitude, and must be coated with other silk yarns.

Spandex coating forms are: empty bag (can obviously see spandex); machine bag (spandex is wrapped inside)

Island composite yarn: It is a composite yarn composed of island silk and high-shrinkage filament mixed network.

High-shrinkage silk: Shrinkage of boiling water reaches 35% (so the rate of suede is large).

Island silk: microfiber, single fiber up to 0.138 (a suede velvet feeling).
