CANVAS: Canvas is made by tightly weaving yarns together in a plain weave, which is a very basic textile weave. The warp (vertical) threads are held steady on the loom, while the weft threads cross over and under each warp. The fibers used in the canvas are thick, usually medium to heavyweight threads (multiply yarns). The threads weight and the plain-weave technique separates canvas from other cotton fabrics.

Most cotton canvas is made with two-ply yarns, or two single yarns twisted together, which adds weight, texture, and creates an even thickness throughout the fabric. Canvas fabrics are usually divided into the coarse canvas and fine canvas.
Coarse canvas, also known as an awning cloth, is usually woven with 10s/ 4-7 ply thread. Those canvas fabrics are known for being durable, sturdy, and heavy-duty. By blending cotton with synthetic fibers, the canvas can become water-resistant or even waterproof, making it a great outdoor fabric for tents, awning, beach parasols, truck covers, and coverings of the open-air warehouse.
Fine canvas warp and weft yarns are generally 10s/2 to 21s/6, which are used to make labor protection clothing and articles. After dyeing, it can also be used as shoes, travel bags, backpacks, etc. In addition, there are rubber canvas, fireproof and radiation shielding canvas, and canvas for paper machines.
The canvas used for art is single-warp canvas, which uses a single-ply yarn.
