What is the difference between cotton canvas and polyester canvas

In life, the use of canvas bags can be said to be very extensive, because it has the characteristics of wear resistance and lightness, and has good applicability for many material industries with wear resistance requirements. Cotton canvas and polyester canvas can be said to be the two most widely used types. So what is the difference between cotton canvas and polyester canvas? 01 Cotton canvas is a thicker cotton fabric or linen fabric. Named for its original use for sails. Generally, plain weave is used, a small amount of twill weave is used, and multi-strand threads are used for warp and weft yarns. Cotton canvas is usually divided into two categories: coarse canvas and fine canvas. Coarse canvas, also known as tarpaulin, is commonly woven with 4 to 7 strands of No. 58 (10 inch), the fabric is firm and foldable, and has good waterproof performance. The warp and weft yarns of fine canvas are generally 2 strands of No. 58 to 6 strands of No. 28 (10 N/2-21 N/6), which are used to make labor protection clothing and supplies. After dyeing, it can also be used as shoes, travel bags, backpacks and other fabrics. In addition, there are rubber canvas, shielding canvas for fire and radiation protection, and canvas for paper machines. Because cotton canvas gains weight after rain, it is rarely used in occasions with high requirements for rain protection, but it is still a good choice for dust-proof padding, because cotton canvas is the most wear-resistant of all canvases. 02 Polyester canvas: Features: high strength, good impact resistance, heat resistance, corrosion resistance, moth resistance, acid and alkali resistance, good light resistance (second only to acrylic fiber), 1000 hours of exposure, 60-70% strength, The hygroscopicity is very poor, the dyeing is difficult, the fabric is easy to wash and dry quickly, and the shape retention is good. Features a 'wash and wear' feature. Uses: Filament: often used as low-elasticity yarn to make all kinds of textiles. Staple fiber: cotton, wool, linen, etc. can be blended. Industry: tire cord, fishing net, rope, filter cloth, insulating material, etc. It is the most used chemical fiber at present. Polyester waterproof canvas, also known as silicone waterproof canvas, has super waterproof performance because of the silicone (fluorine) waterproof treatment. Now it is the main fabric for tents. The disadvantage is that the silicone waterproof coating is washed by rain and snow. The waterproof effect will get worse and worse. Zhongshan LINYANG is located in Zhongshan City.
