Raw material composition of automobile canvas

There are generally three types of fabrics for car canvas (car tarpaulin, car rainproof cloth), which are as follows:

One is PVC-coated fabric, which is woven into a grey fabric with cotton yarn, and then heat-bond the PVC glue to the grey fabric on the upper and lower sides of the grey fabric, so that a percentage of waterproofing can be achieved. Many cars now use this fabric.

The second is: organic frog cloth, which is woven with pure cotton cotton yarn. Generally, the cloth is required to be relatively high, the woven is not dense enough, and it is easy to seep.

The third is: wax canvas. It is on the top and bottom of the cotton canvas, and the wax is dissolved into the canvas. However, this kind of cloth is more advantageous for vacuuming, and it is easy to get dirty.
