What is Polyeter？

Man-made fiber: Polyester: also called polyester fiber, English: Polyeter, full name: polyethylene terephthalate, when burning, the flame is yellow, there is a lot of black smoke, the burning smell is not big, the whole is hard particles after burning, the most widely used, the cheapest price, long fiber, not frizzy, good gloss, not easy to absorb water, easy to be sweet, smooth, static electricity, no elasticity, good tear strength, good physical properties, low cost, the characteristics are good air permeability and moisture discharge, such as 75D, 150D, 300D, 600D, 1200D, 1800D are all polyester, the surface of the fabric is darker than nylon and rougher. (Generally, clothes and bags made of polyester fabrics are cheaper)

What is Nylon？

Man-made fiber: Nylon, English name: Nylon, also called nylon, second only to polyester and polyamide fiber. The advantages are high strength, high wear resistance, high chemical resistance, good deformation resistance and aging resistance. The disadvantage is that it feels hard. The more famous ones are PERTEX and CORDURA. Generally, fabrics with multiples of 70D are nylon, such as 70D, 210D, 420D, 840D, and 1680D are all made of nylon. The gloss of the fabric is brighter and the feel is smoother. Generally speaking, nylon Oxford cloth is used to make luggage. The simplest difference between nylon and polyester is the burning method! Polyester emits strong black smoke, nylon emits white smoke, and the residue after burning is that polyester will break when squeezed, and nylon will become plastic! In terms of price, nylon is twice that of polyester. Nylon shrinks rapidly near flames and melts into a white gelatinous state. It melts, drips and bubbles in the flame. It burns without flames and is difficult to continue burning without flames. It emits a celery smell. After cooling, the light brown molten material is not easy to grind. Polyester is easy to ignite and shrinks near flames. It emits black smoke while melting and has a yellow flame. It emits a fragrant smell. The ashes after burning are dark brown lumps that can be crushed with fingers.

Distingush Polyester and Nylon？

1. Polyester feels rough, while nylon feels smoother. You can also use your fingernail to scratch it. If there is an obvious mark, it is polyester, and if there is no obvious mark, it is nylon.
2. The simplest difference between nylon and polyester is the burning method. Polyester emits strong black smoke, while nylon emits white smoke. Also, look at the residue after burning. Polyester will break when squeezed, while nylon is plastic. In terms of price, nylon is twice as much as polyester.
3. When polyester burns, it produces a puff of black smoke and black ash. 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 resist wrinkles and plasticity. The disadvantage is that it is easy to generate static electricity and pilling.
4. Nylon generally has good elasticity, and the dyeing temperature is 100 degrees, and it is dyed with neutral or acid dyes. It is less resistant to high temperatures than polyester, but has better strength and anti-pilling properties. When burned with fire, the color of the smoke turns white.
