A canvas is a thick cotton or linen fabric. Named for the original use of sails. Generally, plain weave is used, a small amount of twill weave is used, and warp and weft yarns are multi-stranded. Canvas is usually divided into two categories: coarse canvas and fine canvas. The coarse canvas, also known as the tarpaulin, has good waterproof properties, and is used for covering cars and open warehouses as well as tents in the wild. Fine canvas is used to make labor protection clothing and its products. After dyeing or printing, it can also be used as shoe materials, luggage fabrics, handbags, backpacks, tablecloths, tablecloths, etc. In addition, there are rubber canvas, shield canvas for fire and radiation protection, and canvas for paper machine.
There are two kinds of production techniques for waterproof canvas. One is the horizontal machine production, which is the kind of heavy-duty large cylinder. After putting the cloth into the material, it is put on the pila belt and pressed and flattened by the bottom of the heavy-duty large cylinder. Then pull on the dryer to dry, then cut, divide, and package. One is the vertical machine mechanical production, the cloth is pulled straight into the raw material box and pulled out. The glue-like material on the crepe cloth is a high-purity PVC material, and then both sides are straightened straight through the machine with a knife scraping, scraping with a knife After drying, the dryer is trimmed, trimmed, divided, and packaged. There are two types of dryers, one is electric burning and the other is using a boiler. The PVC coated canvas produced by the horizontal machine is cheaper than the PVC coated canvas produced by the vertical machine. The reason is that the horizontal machine requires lower production materials than the vertical machine. The horizontal machine production can be What kind of rubber can be put on and pressed, but the vertical machine can not be produced, the requirements for raw materials are high, and the raw materials must have a certain purity. PVC canvas produced by vertical machines is often slightly more expensive, and the purity of canvas products is also high.
