There is also a strong acid and alkaline resistance, UV resistance. Generally 75D multiples of the fabric is polyester, such as 75D, 150D, 300D, 600D, 1200D, 1800D are polyester, the appearance of the fabric darker than nylon, rough.

Nylon sewing thread is also called Nylon, 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 harder. More famous are PERTEX, CORDURA. Generally 70D multiples of the fabric is nylon, such as 70D, 210D, 420D, 840D, 1680D are nylon material, fabric gloss is brighter, feel smoother. In general, nylon oxford cloth is used as the bag, and the difference between nylon and polyester is the simplest one. Polyester prosperous black smoke, white nylon smoke, there is to see the residue after burning, polyester pinch will be broken, nylon plastic! The price of nylon is double that of polyester. Nylon, near the flame that quickly curled into a white gel, melting in the flame dripping and blistering, there is no flame burning, leaving the flame is difficult to continue burning, emitting celery taste, after cooling the light brown melt is not easy to grind .
