Military backpack fabric requirements.

1.Wear resistance: 

Military backpacks need to withstand a lot of wear, so the fabric must have excellent wear resistance. This can be achieved by using thickened nylon or other wear-resistant materials.

2.Waterproof: 

In order to cope with various weather conditions, the fabric of military backpacks usually needs to be waterproof. This can be done by adding a coating to the surface of the fabric or by using special waterproof materials.

3.Tear resistant: 

Military backpacks may encounter various unexpected situations during use, so the fabric needs to be able to resist tearing. This can be achieved by using high-strength fibers or by adding reinforcing layers to the fabric.

4.Uv resistance: 

Considering that military backpacks may be exposed to sunlight for a long time, the fabric needs to have some UV resistance to prevent damage.

5.Lightness: 

Despite the aforementioned protective properties, the fabric of military backpacks also needs to be kept light so that soldiers can carry them for long periods of time.
