Canvas bag is a kind of thick cotton or linen fabric, which was named after the sail in the early stage. Generally, plain weave is used, a small amount of twill weave is used, and multi strand yarn is used for warp and weft yarn. Canvas bags are usually divided into two categories: coarse canvas and fine canvas. Coarse canvas, also known as tarpaulin, has good waterproof performance. It is often used for automobile transportation, covering of open-air warehouse and camping in the field. Fine canvas is used to make labor protection clothing and its supplies. After dyeing or printing, it can also be used as shoe material, luggage fabric, handbag, backpack, tablecloth, tablecloth, etc. In addition, there are rubber canvas, shielding canvas for fire prevention and radiation prevention, and canvas for paper machine.
