1. Composition
Nylon is a synthetic fiber made from polyamide, while polyester is a synthetic fiber made from polymerizing esters. Nylon is typically produced from petroleum or coal-derived chemicals, while polyester is usually produced from petrochemicals. Nylon and polyester yarns have different chemical structures, which affect their properties and performance.

2. 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.

3. Combustion

The simple difference between nylon and polyester is combustion method! 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.

4. 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 intuitive and easy to distinguish as one method.

5. Strength and Durability
Nylon is known for its strength and durability, making it an ideal choice for applications that require high-strength materials, such as tire cords, ropes, parachutes, and seat belts. Nylon yarns have a high tensile strength and are resistant to tearing, abrasion, and punctures. On the other hand, polyester is less strong and durable compared to nylon, but it has a better resistance to sunlight, mildew, and shrinkage.
