The difference between polyester and nylon

The differences between polyester and nylon are as follows:

1. The specific gravity is different. Polyester 1.38, nylon 1.14;

2. Polyester fabric is not easy to wrinkle, and it is stiff, with good dimensional stability and shape retention. Nylon has poor shape retention, is not as stiff as polyester, and is easy to deform;

3. The melting point of polyester is 260℃ and the ironing temperature can be 180℃. The heat resistance of nylon is not good enough, the ironing temperature should be controlled below 140℃, and the low temperature resistance is good;

4. Nylon has high strength, good elastic recovery, excellent wear resistance, better hygroscopicity and dyeability than polyester;

5. Polyester is resistant to sunlight, acid and alkali. Nylon is alkali-resistant but not acid-resistant, and its light resistance is not good. After long-term exposure to sunlight, its fiber strength will decrease and its color will turn yellow.

6, nylon weaving feels smooth and the surface gloss is high. Clothing materials are more in sportswear, swimsuits, fitness clothes and socks;

The identification of polyester and nylon is as follows:

Nylon:

Combustion phenomenon: it contracts and melts close to the flame, melts and burns in contact with the flame, and continues to burn away from the flame. When burning, there are continuous droplets of melt, which can be drawn into filaments while it is hot. The flame is very small and accompanied by a blue flame.

Smell: unpleasant pungent smell.

Ashes: Black-brown transparent balls.

Polyester:

Combustion phenomenon: it contracts and melts near the flame, melts and burns when it contacts the flame, and continues to burn when it leaves the flame. The flame is yellow and white and very bright.

Smell: unpleasant aroma.

Ash: a dark brown amorphous lump.
