The coarse tarpaulin is also known as the cover cloth. The fabric is fast and durable. It has good waterproof performance. It is used for covering automobile transportation and open-air warehouse and putting tent in the field.
Fine tarpaulin warp and weft yarn is used for making, labour protective clothing and its articles. After dyeing, it can also be used as shoes, travel bags, backpacks and other fabrics. In addition, there are rubber tarpaulins, shielding tarpaulins for fire protection and radiation protection, and tarpaulins used for paper machines.
In short, the size of the yarn is the size of the yarn. At present, in China, it is still "British style", that is, a pound (or 454 gram) weight of cotton yarn (or other ingredients), the length of which is the length of the yarn.
When 840 yards (0.9144 yards / meter), the fineness of the yarn is one. If a pound of yarn is 10 * 840 yards in length, the fineness of the yarn is 10, and the representation of the gauze is the expression of the English letter "S" single yarn.
The 32 single yarn is expressed as follows: the 32S ply line is expressed as follows: 32 strands (two threads and two twists) are 32S/2, 42, 3 and twist: 42S/3.
The density of tarpaulin fabric is calculated in metric system, which refers to the number of yarns arranged in warp and weft yarn in 10cm. The size of the density directly affects the physical and mechanical indexes such as the fabric appearance, the feeling, the thickness, the strength, the bending resistance, the air permeability, the wear resistance and the heating performance. At the same time, he also relates to the cost of the product and the size of the production efficiency.
