What is the difference between nylon and polyester yarn?

Polyester is a kind of synthetic fiber, which is the raw material of chemical fiber fabric. It is not a kind of fabric itself. Polyester is the former name, its scientific name is polyester. The whole process of polyethylene terephthalate is the trade name of polyester fiber. Nylon is nylon, which is called Nylon, polyester and amine fiber. The advantages are high strength, high abrasion resistance, high pitting blood, good deformation resistance and aging resistance, but the disadvantages are hard hand feel. Polyester filament

1. Sensory difference

The luster of the fabric is bright, and the feel is smooth, which is nylon; The appearance of the fabric is darker than nylon, and the coarser is polyester.

2. Combustion

The difference between nylon and polyester. The simple way is combustion! When polyester burns, it emits a lot of black smoke, while nylon emits white smoke. In addition, look at the residue after burning. The polyester will break when pinched, and the nylon will become plastic! The price always says that nylon is twice as much as polyester.

3. Scrape with a nail

In addition, you can use nail scraping. After nail scraping, the obvious trace is polyester, and the inconspicuous trace is nylon, but this method is not as good as The three methods are intuitive and easy to distinguish.

Nylon is generally elastic! The dyeing temperature is 100 ℃. When dyeing with neutral or acid dyes, the high temperature resistance is worse than that of polyester, but the strength is better than that of nylon, anti-pilling, and whitening with burning smoke. Polyester burns black smoke, and the black ash will also float up. The dyeing temperature is 130 ℃ (high temperature and high pressure), and the hot-melt method is generally baked below 200 ℃. Polyester is mainly characterized by good stability. Generally, adding a small amount of polyester in clothes can help prevent wrinkles and shape, but the disadvantage is that it is easy to generate static electricity and fuzz balls. The shortcomings of the current polyester have been improved.
