Canvas is a thicker cotton or linen fabric. Named because it was originally used for sails. Generally, plain weave is used, and a small amount of twill weave is used. Multi-strand yarn is used for warp and weft. Canvas are usually divided into two categories: coarse canvas and fine canvas. In addition, there are rubber canvas, shielding canvas for fire and radiation, and canvas for paper machine.
Coarse canvas, also known as tarpaulin, is commonly woven with No. 58 (10 English) 4-7 strands. The fabric is strong and resistant to folding and has good waterproof performance. It is used for automobile transportation, open-air warehouse cover and outdoor tents.
Fine canvas warp and weft yarns are generally 2 strands No. 58 to 6 strands No. 28 (10 British counts/2-21 British counts/6), which are used to make labor protection clothing and supplies. After dyeing, it can also be used as fabrics for shoes, travel bags, backpacks, etc.
The fabric density of canvas is calculated in metric system, which refers to the number of warp and weft yarns arranged in one square inch. The density directly affects the appearance, feel, thickness, strength, flexural resistance, air permeability, abrasion resistance, and thermal performance of the fabric. It also affects the cost and production efficiency of the product.
