Difference between nylon thread and polyester thread

2024-01-25

The difference between polyester and nylon is as follows:

1, the specific gravity is different. Polyester 1.38, nylon 1.14.

2, polyester fabric is not easy to wrinkle, and straight, good dimensional stability, good conformability. Nylon conformability is not good, no polyester straight, easy to deform; 3, the melting point of polyester is in the range of 1.38 to 1.14.

3, polyester melting point at 260 ℃, ironing temperature can be 180 ℃. Nylon heat resistance is not good enough, ironing temperature should be controlled below 140 ℃, good low temperature resistance.

4, nylon high strength, good elastic recovery ability, good abrasion resistance, moisture absorption and dyeing are better than polyester.

5, polyester is resistant to sunlight, acid but not alkali. Nylon alkali resistance but not acid resistance, light resistance is not good, long-term exposure to sunlight under the fiber strength will decline, the color turns yellow.

6, nylon weaving feel smoother, higher surface gloss. Clothing in sportswear, swimwear, bodybuilding clothing, socks are more;.

Polyester and nylon are recognized as follows:

Nylon:

Burning phenomenon: close to the flame contraction melting, contact with the flame melt burning, away from the flame to continue to burn, burning constantly melt drop, while hot can be pulled into a thin wire, the flame is very small, and accompanied by blue flames.

Odor: unpleasant pungent odor.

Ash: Dark brown transparent ball.

Polyester:

Burning phenomenon: contraction and dissolution near the flame, melting and burning in contact with the flame, continue to burn away from the flame, the flame is yellowish-white, very bright.

Odor: unpleasant aromatic smell.

Ash: black-brown indeterminate hard lumps.
