Classification of tarpaulins
Classification of tarpaulins and tarpaulin( or canvas tarps ) is a leakproof material with high strength, good durability, and wimpiness. It’s frequently used as an oil, polyester with a polyurethane coating, or made into polyethylene plastic. 12×24 tarps heavy-duty waterproof tarps generally have strong grommets at the corners for easy rope tying, hanging, or covering.

Tarpaulins are generally divided into two orders coarse tarpaulins and fine tarpaulins. Classification of tarpaulins for Ldpe tarpaulin, tarpaulin sheeting, tarpaulin cover, waterproof tarpaulin, plastic tarpaulin, heavy-duty PVC tarpaulin, Woven tarpaulin fabrics, truck cover tarpaulin, tarps for pools, and other custom tarps.
The coarse tarpaulin is also called poly tarp, the fabric is strong and resistant to folding, and has good leakproof performance. It’s used for covering machine transportation and open storages and setting up canopies in the wild.
The underpinning and weft yarns of fine tarpaulins are used for making labor protection apparel and its inventories. After being bepainted, it can also be used as fabric for shoes, trip bags, packs, etc. In addition, there are rubber tarpaulins, shielding tarpaulins for fire protection and radiation protection, and garden tarps for paper machines.
In short, the yarn count refers to the consistency of the yarn. The common bone
in China is still the “British system”, that’s one pound( 454 grams) of cotton yarn( or other element yarns), the length is
At 840 yards (0.9144 yards/ cadence), the fineness of the yarn is one-piece. However, the representation system of the yarn count is the English letter “S”, If a pound of yarn has a length of 10 x 840 yards and a fineness of 10 counts. The representation system of a single yarn is
32 single yarns——- expressed as 32S beaches are expressed as 32 beaches( two beaches and crooked) are 32S/ 2, 42 beaches and 3 beaches are twisted 42S/ 3.
The computation unit of tarpaulin fabric viscosity is in the metric system, which refers to the number of underpinning and weft yarns arranged within 10 cm. The size of the viscosity directly affects the physical and mechanical pointers similar to the appearance, feel, consistency, strength, folding resistance, air permeability, wear resistance, and thermal performance of the fabric, and it’s also related to the cost of the product and the size of the product’s
This system is suitable for regular fabrics with high viscosity and small yarn count. First, after assaying the fabric structure and the number of spiraled underpinning yarns in the structure
(Number of spiraled weft yarns in the towel), and also multiplied by the number of circles in the towel in 10 cm, the product attained is the underpinning( weft) yarn viscosity.
The direct dimension system is fulfilled by means of a cloth glass or a fabric viscosity analysis glass. The scale length of the fabric viscosity analysis glass is 5 cm. Under the analysis lens, there’s a red line engraved on a long glass piece. When analyzing the fabric viscosity, move the lens and align the red line on the glass piece and the red line on the scale at two points at the same time. Between the yarns, take this as the starting point, and count the number of yarns while moving the camera, until the 5 cm scale line is then. The number of affair yarns is multiplied by 2, which is the viscosity value of the 10 cm fabric.
When counting the number of yarns, the center between the two yarns should be used as the starting point. However, further, than 0, If the number reaches the endpoint. 5 yarns and lower than one yarn should be counted as 0.75 yarns.
If it’s lower than 0.5 roots, it’ll be calculated as 0.25 roots. Generally, 3- 4 data should be measured for fabric viscosity, and also the computation mean value should be taken as the dimension result.
3. Gram weight
Refers to the weight in grams of one square cadence of fabric.
Woven tarpaulin fabrics use” ounces”,” an” or” OZ” knitted tarpaulins generally use gram weight( g/ m2) Its conversion is that 1 ounce is equal to 28.375 grams, but it’s generally counted on the importing machine
grams, which is related to the yarn count and the underpinning and weft viscosity of the fabric. The thicker the yarn, the thicker the cloth, and the lesser the weight in grams. Thank you and please check the web: www.kgpackage.com
