The difference between polyester, polyamide and nylon
- Sep 05, 2018 -

1, polyester - polyester fiber

Also known as POLYESTER, the properties are good breathability and moisture wicking. There is also a strong resistance to acid and alkali, UV resistance. Generally, the fabric of the multiple of 75D is polyester, such as 75D, 150D, 300D, 600D, 1200D, 1800D are polyester, the appearance of the fabric is darker than nylon, and is rough.


2, Polyamide - nylon


Also known as Nylon, polyamide fiber. The advantages are high strength, high wear resistance, high chemical resistance, good deformation resistance and aging resistance. The disadvantage is that the hand feels harder. More famous are PERTEX, CORDURA. Generally, the fabric of multiples of 70D is nylon, such as 70D, 210D, 420D, 840D, and 1680D are made of nylon. The gloss of the fabric is brighter and the hand feels smoother.


Generally speaking, all the bags are made of nylon oxford. The difference between nylon and polyester is the simplest method of combustion! Polyester's very strong black smoke, nylon's white smoke, and the burning residue, polyester pinch will be broken, nylon plastic! The price of nylon is twice that of polyester.


Nylon, the near flame is rapidly curled and melted into a white gel. It melts and blisters in the flame, and there is no flame when burning. It is difficult to continue burning after leaving the flame, and the celery flavor is emitted. After cooling, the light brown melt is not easy to be broken. .


Polyester, easy to ignite, near the flame is melted, burning while burning black smoke, a yellow flame, emitting aroma, after burning, the ash is a dark brown lumps, can be broken with fingers.


The other hand feels different. The polyester feels rougher and the nylon feels smoother.


In addition, you can use a nail scraper. After the nail is scraped, there is a clear trace of the rayon. The trace is not obvious is nylon, but this method is not as straightforward as the first method.


Polyester: close to the flame - softening, melting and curling, in the flame - melting, slow burning, yellow flame, flame side blue, flame top black smoke, leaving the flame - continue to burn, sometimes stop burning and self Off. Burning odor - slightly aromatic or sweet. Residue characteristics - the ash path is hard and black, and it is not easy to crush with fingers.


Nylon-nylon: close to flame--combustible softening shrinkage. In the flame - curling, melting, burning slowly, producing small bubbles, the flame is very small, blue. Leave the flame - stop burning and self-extinguish. Burning odor - amino or celery. Residue characteristics - the ash path is hard and black, and it is not easy to crush with fingers.


So, what are the differences in performance? Simply put, nylon has better performance than polyester, but at a higher cost than polyester. Nylon products are better than polyester products in terms of abrasion resistance, strength, color fastness and gloss, and are not easy to produce dead wrinkles.


On the hand, nylon is soft and polyester is hard!
