The canvas factory tells you the raw materials of the canvas and the safety distinction of the canvas

Canvas A thicker cotton or linen fabric, named for its original use for sails. Generally, plain weave is used, and a few varieties use twill weave, and multi-strand threads are used for warp and weft yarns. Coarse canvas, also known as tarpaulin, is commonly woven with 4 to 7 strands of No. 58 (10 inch), the fabric is firm and resistant to twists and turns, and has good waterproof performance. Wait. The fine canvas warp and weft yarns are generally 2 strands of No. 58 to 6 strands of No. 28 (10 N/2 to 21 N/6), which are used for labor protection clothing and supplies. After dyeing, it is also used as shoe fabric, travel bag, backpack and canvas box material. Some of the fine canvas used in shoemaking can be woven into a double-layer organization, which combines the upper and the lining of the shoe into one, which can improve the quality of the upper. In addition, there are rubber canvas, shielding canvas for heat, fire and radiation protection, canvas for paper machines, etc. The rubber canvas requires high strength in the warp and weft direction, uniform warp and weft density, small interweaving gap difference between warp and weft threads, and no oil stains, which is conducive to the uniform penetration of the glue when the rubber is applied. Canvas for paper machine requires thick cloth body, suitable softness and hardness, clean and smooth cloth surface, and good moisture permeability. The raw materials of canvas have been developed to chemical fiber and glass fiber, which makes the canvas have better performance.
