What is the difference between polyester and nylon

1. Polyester --- Polyester fiber, also known as POLYESTER, is characterized by good air permeability and moisture removal. It also has strong anti-acid and alkali resistance and anti-ultraviolet ability. Generally, the fabrics with multiples of 75D are polyester, such as 75D, 150D, 300D, 600D, 1200D, 1800D are polyester, the appearance of the fabric is darker and rougher than nylon.
2. Nylon --- Nylon, also known as Nylon, is polyamide fiber. The advantages are high strength, high wear resistance, high chemical resistance, and good resistance to deformation and aging. The disadvantage is that it feels hard. The more famous ones are PERTEX and CORDURA. Generally, the fabric with multiples of 70D is nylon, such as 70D, 210D, 420D, 840D, and 1680D, which are all nylon materials. The gloss of the fabric is brighter and the hand feel is smoother. Generally speaking, nylon Oxford cloth is used for bags. The simplest difference between nylon and polyester is the burning method! It will be broken when squeezed, and nylon will become plastic! The price of nylon is twice that of polyester. Nylon, quickly curls and melts into a white gel when near the flame. It melts and drips and bubbles in the flame. There is no flame when burning. It is difficult to continue to burn when it leaves the flame. . Polyester, easy to ignite, melts near the flame, emits black smoke while burning, turns yellow flame, emits a fragrant smell, after burning, the ashes are dark-brown lumps, which can be crushed with fingers. The hand feel will also be different. Polyester feels rough, nylon feels smoother. In addition, you can scrape with your nails. After scraping the nails, there are obvious marks on the nylon, and the ones with less obvious marks are nylon, but this method is not as good as the first method. A method that is intuitive and easy to argue.
