Tarpaulin is a kind of waterproof material with high strength, good toughness and softness. The tarpaulin usually has strong nooks at the corners or edges to make it easy to tie, hang, or cover with ropes.

Tarpaulin is usually divided into thick tarpaulin and thin tarpaulin two types.

Tarpaulin, also known as awning cloth, fabric fast folding resistance, has good waterproof performance, used for car transport and open warehouse cover and field tent. Thin tarpaulin warp and weft yarn is used to make labor protection clothing and articles. After dyeing can also be used as shoes, travel bags, backpacks and other fabrics.

Yarn count refers to the thickness of the yarn. The common practice in China is still the "British" system, which means that cotton yarn (or yarn of other components) weighing one pound (454 g) in length of 840 yards (0.9144 yards/m) has a single finness.

The measurement unit of tarpaulin fabric density in the metric system is the number of warp weft threads arranged within 10cm. The size of the density directly affects the appearance, feel, thickness, strength, flexability, air permeability, wear resistance and thermal properties of the fabric and other physical and mechanical indicators.
