What is the difference between nylon and polyester yarn

Polyester is a synthetic fiber and the raw material of chemical fiber fabrics. It is not a fabric itself. Polyester is the previous name, the scientific name is polyester, and the whole process is polyethylene terephthalate, which is the trade name of polyester fiber. Nylon is nylon, which is called Nylon, polyester amine fiber. The advantages are high strength, high wear resistance, high pitting blood, and good resistance to deformation and aging, but the disadvantage is that it feels hard.
1. Sensory difference
The gloss of the fabric is brighter and the feel is smoother than nylon; the appearance of the fabric is darker than that of nylon, and the rougher one is polyester.
2, burning
The difference between nylon and polyester is simply the burning method! Polyester emits very strong black smoke when it burns, while nylon emits white smoke. The other is to look at the residue after burning. Polyester will be broken when squeezed, and nylon will become plastic! The price has always been that nylon is twice as expensive as polyester.
3. Scrape with your fingernails
In addition, you can use your fingernails to scrape. After the nails are scraped, the obvious traces are polyester, and the less obvious traces are nylon, but this method is not as intuitive and easy to understand as a method.
Which is better nylon or polyester?
Nylon generally has better elasticity! The dyeing temperature is 100 degrees, and it is dyed 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 the color of burning smoke is white. The polyester burned with black smoke, and the black ash also floated up. The dyeing temperature is 130 degrees (high temperature and high pressure), and the hot-melt method is generally baked below 200 degrees. The main feature of polyester is good stability. Generally, adding a small amount of polyester to clothes can help wrinkle resistance and shape. The disadvantage is that it is easy to generate static electricity and pilling. Now the polyester has been improved and the shortcomings have been improved.
