Plain

Plain weave is the most basic of three fundamental types of textile weaves (along with Ripstop and twill). It is strong and hard-wearing, and is used for Bulletproof or Tactical vest fabrics. In plain weave fabrics, the warp and weft threads cross at right angles, aligned so they form a simple criss-cross pattern. Each weft thread crosses the warp threads by going over one, then under the next, and so on. The next weft thread goes under the warp threads that its neighbor went over, and vice versa.

Waterproof

Waterproof refers to that water can’t penetrate through the fabric back side in specific pressure. Generally, it will coat PU or PVC coating on the chemical fabric backside to make the waterproof function. Some fabric will laminate Polytetrafluoroethylene (PTFE) membrance to make it waterproof. This function usually won’t invalid by washing and long-term use.

Water repellent (WR)

Water repellent (WR), also known as water resistant. By adding auxiliaries to make the surface of the fabric has a very low surface tension. After the water drops fall, the tension on the surface of the fabric is very large, which promotes the shrinkage of the surface of the water droplets. It is spherical and cannot be spread out, so it quickly slips off the fabric in the form of water droplets. But after multiple washings, the effect of water repellent will decrease.
