Tarpaulin (or waterproof cloth) is a kind of waterproof material with high strength, good toughness and softness. It is often used as canvas (oil canvas), polyester coated with polyurethane or made into polyethylene plastic. Tarpaulins usually have strong grommets at the corners or edges to facilitate binding, hanging or covering with ropes.
Tarpaulins are usually divided into two categories: coarse tarpaulins and fine tarpaulins.
Coarse tarpaulin is also called tarpaulin. The fabric is strong and resistant to folding and has good waterproof performance. It is used for automobile transportation and open-air warehouse covering and tents in the field.
Fine tarpaulin warp and weft yarns are used to make labor protection clothing and its supplies. After dyeing, it can also be used as fabrics for shoes, travel bags, backpacks, etc. In addition, there are rubber tarpaulins, shielding tarpaulins for fire and radiation protection, and tarpaulins for paper machines.
1. Yarn count:
To put it simply, yarn count refers to the thickness of the yarn. What is commonly used in China is the "imperial system" that is: one pound (454 grams) of cotton yarn (or other component yarn), and the length is
At 840 yards (0.9144 yards/m), the yarn fineness is one piece. If one pound of yarn has a length of 10×840 yards and a fineness of 10 yarn counts, the representation method of the yarn count is the English letter "S". The representation method of a single yarn is:
32 single yarns-------expressed as: 32S strands are expressed as: 32 strands (two twists in parallel) is: 32S/2, 42 strands and 3 twists are both: 42S/ 3.
2. Density:
The calculation unit of the density of tarpaulin fabric is in metric system, which refers to the number of warp and weft yarns arranged within 10cm. The density directly affects the appearance, feel, thickness, strength, flexural resistance, air permeability, abrasion resistance, and thermal performance of the fabric. It also affects the cost and production efficiency of the product.
