which is the most durable polyester?

 Which is the most durable polyester?

For bags, we normally use the polyester, but polyester is a gernerally called for the textiles. 

That means, the PA (POLYAMIND), TERYLENE could be  all called polyester. 

However, Polyamind is more duable than terylene, and it usually used for industiral purpose, 

for our rebag bag items, terylene will be durable enough, sometimes, we use nylon material. 

But we have a middle way, that make the textiles by terylene, and use PA (nylon) coated for 

for the surface for this material, so that we get the both advantages:  cheaper for the textiles

but much more durable. 

For rebag bags, we also do the same material: 190T,  210T, 210D, 420D(not coated), terylenes 

for lining, 420D coated, 600D, 300D , 70D, 1680D material as the outside material. it will be 

much more depends on the bag purpose, the functions and budget from the customers. Such

as the backpack, the postman bag, the makeup bags, the 600D material will be regularly found. 

So the question is, which is the durable material, of course, the 1680D is the high density and 

durable. This is also the terylene, with PVC, PU, coated, but this is only for bag items, not compared

with industrial textiles.


There is another question: what's the difference between Terylene and Polyamind: 

1. Polyester --- polyester fiber

Also known as POLYESTER, it is characterized by good air permeability and moisture desorption. 

There is also strong resistance to acids and alkalis, and UV resistance. Generally, the fabrics with 

multiples of 75D are polyester, such as 75D, 150D, 300D, 600D, 1200D, and 1800D. The fabric is 

darker and rougher than nylon.

2. Nylon --- 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 t

hat it feels hard. The more famous ones are PERTEX and CORDURA. Generally, fabrics that are multiples

 of 70D are nylon. For example, 70D, 210D, 420D, 840D, and 1680D are all nylon materials. The fabric 

has a brighter gloss and a slippery feel. Generally speaking, all bags are made of nylon oxford cloth. 

The simplest difference between nylon and polyester is the burning method! The black smoke of polyester, 

the white smoke of nylon, and the residue after burning, the kneading of polyester will shatter, and the 

plastic of nylon! The price of nylon is twice that of polyester. Nylon, near the flame, quickly curls and melts 

into a white gel. It melts and drops and bubbles in the flame. There is no flame when burning. It is 

difficult to continue burning away from the flame. It emits a celery smell. The light brown melt is not easy 

to grind after cooling. . Polyester is easy to ignite, and it melts when it is near the flame. When it burns,

 it emits black smoke while melting. It shows a yellow flame and emits an aromatic smell. After burning, 

the ashes are dark brown lumps, which can be broken with fingers.

In addition, the hand feel will be different. Polyester feels rougher, while nylon feels smoother. In addition, 

you can use your nails to scrape. After the nails are scraped, there are obvious traces of tape, and the less 

obvious traces are nylon, but this method is not as good as the first One method is intuitive and easy to argue.
