Canvas is very common. It is a rain-proof and waterproof shelter commonly used in construction, transportation and other industries. It has good waterproof property and is widely used in our life. In addition, we also wear canvas shoes. But is canvas for these two purposes a kind of canvas?
The origin of the name of canvas is that this kind of rain-proof and wind-proof cloth was originally used on sailboats, and the reason why canvas is waterproof is that PVC glue is applied on the surface of cotton and hemp base cloth, which is also why the canvas shoes we usually wear are not waterproof and are used for the waterproof of canvas for transportation or industrial production.
In the early days when there was no chemical fiber or glass fiber, cotton and hemp canvas was an important rainproof tarpaulin. With the advent of glass fiber, glass fiber cloth as the base cloth of some special cloth had better toughness and flexibility, so glass fiber canvas began to become popular. Because glass fiber did not burn, glass fiber canvas was often used for fire protection.
Glass fiber canvas is commonly known as fire resistant canvas or fire resistant cloth. The base cloth is woven with glass fiber and the surface is PVC coated. Due to the problems of glass fiber and PVC materials, glass fiber canvas cannot be completely waterproof. Its main characteristics are fire resistance, high temperature resistance, dust prevention, mildew resistance and good permeability. It is a good material for making fire resistant door curtain and machine fire and dust resistant canvas cover.
