The description of the fabric on the general backpack specification is not very detailed, but it is CORDURA or HD. What it says is just a textile method. If more detailed description should be material + fiber + textile method. For example: N. 1000D CORDURA, that is 1000D nylon CORDURA material.
Many people think that the "D" in the backpack material represents density or weight. This is wrong. D is the abbreviation for denier. Denier is a measure of fiber. The calculation method is: 1 gram weight per 9,000 meters long is called Denier. So the smaller the number in front of D, the finer the line and the lower the density. For example 210D material, the texture is particularly thin, generally used as a bag inside or compartment. The grain lines of 900D or 1000D are thick, and the lines are also thick and very wear-resistant. Generally, they are used as a package bottom.
First of all, the material used for the fabric used on the bag is Nylon and Poly. Occasionally, two materials are mixed together. Nylon is nylon and Poly is polyethylene. Both of these materials are extracted from petroleum. Nylon is a little better than Poly, but it is certainly more expensive. From the fabric, Nylon feels softer.
Here are some of the fabrics that often appear in backpacks:
1. CORDURA
It is a kind of fabric invented by DuPont. It has the functions of light weight, quick drying, softness, and durability. It is not easy to change color when used for a long time. It is said that such fabrics will appear in two colors at different angles, except for DuPont's companies who do not know how to produce this material. Nylon is generally woven into the fabric, Denier as the strength standard, there are 160D, 210D, 330D, 420D, 600D, 900D, 1000D, etc. The higher the number, the stronger, the thicker the lines. Generally 160D to 210D is used on clothes or as a general outdoor bag. The reverse side of this material is coated, and moderate rain does not wet the material.

2. KODRA
KODRA is a fabric produced in Korea. To some extent it can replace CORDURA. It is said that the inventor of this fabric originally wanted to study how CORDURA was spun. At the end, no research was done but a new fabric was invented. This is KODRA. This fabric is generally woven with Nylon, and is also based on fiber strength standards, such as 600D, 1000D. The reverse side is coated, which is similar to CORDURA.
3. OXFORD
Oxford's warp threads are woven from two strands of thread, and the weft threads are also relatively thick. Its textile method is one up and down, it is a very general textile method. Generally 210D, 420D material. The reverse side is coated. Used as a bag inside or compartment.
4.HD
HD is an abbreviation of High Density, meaning high density. Look at fabrics and OXFORD almost. Usually 210D, 420D, usually used as a bag inside or compartment. The reverse side is coated.
5.R/S
R/S is short for Rip stop. This fabric is a small square of nylon. Its toughness is stronger than normal nylon. The outside of the square on the fabric is a thicker line. The middle of the square is woven with very thin threads. Generally 300D, 330D, 450D, etc., can be used as the main material of the backpack, such as the big side, outside the pocket and other parts. The reverse side is coated.
6.Dobby
Dobby's fabric seems to have a lot of very small grids, but if you look closely, it will be found that it is woven from a thick and thin two lines, the front and back lines are not the same. Generally little coating. The intensity is much worse than that of Cordura, and it is generally only used in casual bags or short trip bags. Do not use on mountaineering bags.
7.VELOCITY
VELOCITY is also a nylon cloth. High strength. It is also commonly used on mountaineering bags. The reverse side is coated. Has 420D or higher strength. The front of the fabric looks like Dobby.
8. TAFFETA
TAFFETA is a very thin coated fabric, some coatings more than once, so the waterproof performance is better. The main fabric, which is not a backpack, is usually a raincoat or a rain cover for a backpack.
9.Poly PU
It is generally replaced with Poly. Poly density is generally 64t (low), 74t (medium), and 82t (high). Fabric strength from 150D to 1800D is getting stronger. The general high intensity of 600D can be used as the bottom of the bag, but its textile method is not as strong as CORDURA.
10. AIR MESH
General Chinese is called it Space Network, it is different from the general network. Its mesh has a gap with the material below, typically 3mm or more. It is this kind of gap that gives it good ventilation properties, so it is generally used as a strap or back or other place close to the body.
11.Mesh
The general network has many specifications and is not introduced one by one. Nylon nets are usually used on bags only on both sides of the bag as a sundries pocket or water pocket.
The above is a brief introduction to the main ingredients used in general backpacks. Just for your reference, if you have any suggestions, please send them.
