Explanation of common specifications and terms of tarpaulin products

Explanation of common specifications and terms of tarpaulin products: When purchasing tarpaulin products such as canvas tents, you will often see the introduction of similar terms such as yarn count, density and other professional terms. The specific parameters, then let's learn the name explanation together.

In short, the yarn count refers to the thickness of the yarn. The "Imperial system" is still commonly used in China, that is: one pound (454 grams) of cotton yarn or other component yarns with a length of 840 yards (0.9144 yards/meter). , the fineness of the yarn is one. If a pound of yarn, its length is 10*840 yards, its fineness is 10, and the representation method of yarn count is the English letter "S". The representation of a single yarn is: 32 single kills -- --- Expressed as: 32S strands are expressed as: 32 strands (two twisted in parallel) are: 32S/2, 42 strands of 3 twisted: 42S/3.

Density, the calculation unit of tarpaulin plant density is in metric system, which refers to the number of warp and weft yarns arranged within 10cm. The consignment of density directly affects the physical and mechanical indicators of the fabric's appearance, feel, thickness, strength, folding resistance, air permeability, weather resistance and thermal insulation performance, and it is also related to the cost of the product and the size of the production efficiency.

Gram weight: refers to the weight in grams of one square meter of fabric. Woven tarpaulin fabrics use "ounces", "an" and "OZ". Knitted tarpaulins generally use gram weight (g/m2). 1 ounce is 28.35 grams, which is related to yarn count and fabric warp and weft density. The thicker the yarn, the higher the density of the cloth. The thicker it is, the greater the gram weight.
