What are backpacks made of?

What are the best business laptop backpacks made of? Let's talk about the material. Generally, the raw materials of the fabric used on the bag are Nylon and polyethylene, and occasionally the two materials are mixed together. Both of these materials are extracted from petroleum. Nylon is a bit better in quality than polyethylene, and of course it is a bit more expensive. In terms of fabric, Nylon feels softer.

Many people think that the "D" in the backpack material represents density, or weight. This is wrong. D is the abbreviation of denier. Denier is a unit of measurement for fiber. The calculation method is: every 9,000-meter-long line weighs 1 gram and is called Denier. Therefore, the smaller the number in front of D, the thinner the line and the smaller the density.

For example, the material of 210D has very fine texture, which is generally used as the lining or the compartment of the bag. The 900D or 1000D material has thick texture and thick thread, which is very wear-resistant, and is generally used as the bottom of big backpacks.

The following is a brief introduction to some fabrics that often appear in backpacks:

It is a kind of fabric invented by DuPont. It has the functions of lightness, quick-drying, softness and strong durability, and it is not easy to change color after long-term use. It is said that this kind of fabric will appear in two colors from different angles. Except for DuPont's company, no one else knows how to produce this material.

Generally, it is woven with Nylon, with fiber density (Denier) as the strength standard. There are 160D, 210D, 330D, 420D, 600D, 900D, 1000D, etc. The higher the number, the stronger the texture and the thicker the texture. Generally 160D to 210D are used on clothes or as the inside of general large travel backpack. This material has a coating on the reverse side, so normal rain will not soak the material.

2. K0DRA
K0DRA 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 woven. In the end, it was not researched, but a new fabric was invented. This is K0DRA. This fabric is generally used
Nylon is woven with fiber degree as the strength standard, such as 600D and 1000D. There is a coating on the reverse side, similar to CORDURA.

The warp yarn of Oxford spinning is woven from two strands, and the weft yarn is relatively thick. The weaving method is one up and down, which is a very general weaving method. Generally 210D, 420D material. The reverse side is coated. Used as the lining or compartment of the bag.

HD is short for High Density, meaning high density. The fabric is similar to 0XFORD. Generally 210D, 420D, usually used as the lining or compartment of the bag. The reverse side is coated.

5. R/S
R/S is short for Rip stop. This fabric is nylon with small squares. Its toughness is stronger than normal nylon, and the outer squares on the fabric are thicker threads. The middle of the square is woven with very thin threads. Generally there are 300D, 330D, 450D, etc., which can be used as the main material of backpacks, such as large areas and outer pockets. The reverse side is coated.

6. Dobby
Dobby's fabric seems to consist of many very small grids, but if you look closely, you will find that it is woven from two kinds of threads, one thick and one thin, and the lines on the front and back are different. There is generally very little coating. The strength is much worse than Cordura, generally only used on leisure bags or excursion bags and not on hiking bags.

VELOCITY is also a nylon cloth. The intensity is high. Generally used on mountaineering bags. The reverse side is coated. There are 420D or higher strength. The front of the fabric looks a lot like Dobby.

What are backpacks made of?

TAFFETA is a very thin coated fabric, and some are coated more than once, so the waterproof performance is better. Generally not the main fabric of the backpack, only the raincoat or the rain cover of the backpack.

9.Polyethylene PU
Generally use polyethylene instead. The density of polyethylene is generally 64t (low), 74t (medium), and 8t (high). The strength of the fabric is getting stronger and stronger from 150D to 180D. Generally, those with a high strength of 60D can be used as the bottom of a mountaineering bag, but its textile method is not as strong as CROURA.

It is different from the general net. There is a gap between its mesh surface and the material below, generally 3mm or larger. And it is this kind of gap that makes it have good ventilation performance, so it is generally used as a harness or back or other places close to the body.

11. Mesh
There are many specifications for general nets, not to introduce them one by one. Nylon nets are generally only placed on both sides of the bag as a sundries pocket or water pocket.
