Here are some of the fabrics that are often present in backpacks:
1. KODRA
KODRA is a fabric produced in Korea. To a certain extent it can replace CORDURA. I heard that the inventor of this fabric originally wanted to study how CORDURA was spun, and eventually it was not studied but it invented a new fabric. This is KODRA. This fabric is generally woven with Nylon, and is also based on fiber strength specifications, such as 600D, 1000D. It is not coated with CORDURA.
Special attention is given to Tetron Kodra, actually tetoron Kordra is a poly/nlon blended fabric
2. 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. Discordant and coated. Used as a bag inside or compartment.
3. CORDURA
It is a fabric invented by DuPont and it has the functions of light weight, quick dryness, softness, and durability. It is also not easy to change color during long-term use. It is said that such fabrics will appear in two colors at different points of view, except for DuPont's companies who do not know how to produce this material. Generally made of Nylon weaving, with Denier as the strength specification, there are 160D, 210D, 330D, 420D, 600D, 900D, 1000D, etc. The higher the number, the stronger and the thicker the texture. Generally 160D to 210D may be used on clothes as a general outdoor bag. This type of material is not coated and the medium rain will not soak the material.
4.HD
HD is an abbreviation of High Density, meaning high density. Look at fabrics and OXFORD almost. Generally 210D, 420D, generally used as a bag inside or compartment. Discordant and coated.
5.Dobby
Dobby's fabric is composed of many subtle grids, but if you look closely, it will be found that it is woven from a thick and thin two lines, and the front and the discord texture are not the same. Generally little coating. The strength is much worse than that of Cordura and is generally only used on leisure bags or short trip bags. Do not use climbing bags.
6.VELOCITY
VELOCITY is also a nylon cloth. High strength. It is also commonly used on climbing bags. Discordant and coated. Has 420D or higher strength. The front of the fabric looks like Dobby.
7.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 grid center 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 face, the outer pocket and other parts. Discordant and coated.
8. TAFFETA
TAFFETA is a very thin coated fabric, and some coatings more than once, so the waterproof function is better. Generally do not make the main fabric backpack, only raincoats, perhaps a backpack rain cover.
9. AIR MESH
General Chinese is called it Space Network, it is different from the general network. Its mesh surface and the following material have a space, usually 3mm or more. It is this kind of vacant land that gives it outstanding ventilation, so it is generally used as a back strap or perhaps the rest of the body.
10.Poly PU
Replaced by Poly. Poly density is generally 64t (low), 74t (medium), and 82t (high). Fabric strength from 150D to 1800D is getting stronger. The general high strength of 600D can be used as the bottom of the climbing package, but its textile approach is not as robust as CORDURA.
11.Mesh
There are many standards in the general network and they are introduced differently. Nylon nets are generally used on bags only on either side of the bag as a debris pocket or water pocket.
