Commonly used backpack fabric introduction

- Jun 20, 2018-

First of all, the material used for the fabric used on the backpack 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.

Oxford Nylon (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.

Imitation DuPont Nylon (KODRA)

KODRA is a fabric produced in Korea. To a certain extent it can replace CORDURA. It is said that the inventor of this fabric originally wanted to study how CORDURA was spun. In 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 as the standard, such as 600D, 1000D. The reverse side is coated, which is similar to CORDURA.

High Density Nylon (HD)

HD is an abbreviation for High Density, meaning high density. Look at the fabric and OXFORD almost. Usually 210D, 420D, usually used as a bag inside or compartment. The reverse side is coated.

Plastic nylon (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 face, the outer pocket and other parts. The reverse side is coated.

Tig Nylon (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 the back of the 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.

Super Velocity Nylon (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 very much like Dobby.

Waterproof nylon (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.

Poly PU

Generally use Poly instead. Poly density is generally 64t (low), 74t (medium), and 82t (high). Fabric strength is increasing from 150D to 1800D. The general high strength of 600D can be used as the bottom of the bag, but its textile method is not as strong as CORDURA.

Space Network (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. In general, there are many specifications for nets. Nylon nets are usually used on bags as debris or water pockets on both sides of the bag.

1. Polyester --- Polyester Fiber

Also known as POLYESTER, the characteristics are good breathability and moisture absorption. There is also a strong acid and alkaline resistance, UV resistance.

2. Spandex --- Telescopic nylon

Also known as SPANDEX, it has the advantages of high elasticity, high flexibility and good recovery. The general use of 2% can increase the fabric's sense of movement, as well as the drapability and shape retention. Weaknesses are weaknesses in alkali resistance; yellowing and embrittlement can occur after exposure to chlorine or exposure to ultraviolet light. Poor heat resistance. Often used as an auxiliary material blended with other materials.

3. Nylon --- Nylon

Also known as 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.

Above are the materials that are commonly used on backpack bags.
