How to test the density of tarpaulin

The density of the tarpaulin manufacturer is an important factor to weigh the waterproof function of the tarpaulin. The size of the density will directly affect the appearance, feel, thickness, strong separation, folding resistance, air permeability, wear resistance and thermal insulation performance of the fabric. and other physical and mechanical targets

The calculation unit of tarpaulin fabric density is in metric system, which refers to the number of warp and weft yarns displayed within 10cm, then when testing tarpaulin density, if you roughly estimate the density of tarpaulin, the number of yarns is small, and the regular For organization, the direct test method can be used. First of all, it is to analyze the weave of the fabric and the number of weave loops (the number of weft loops), and then multiply the number of weave loops in 10cm, and the resulting product is the warp (weft). ) yarn density. If it does not belong to the above-mentioned types of tarpaulin, and the tarpaulin factory, it is to use the direct measurement method, that is, to rely on the cloth mirror or the fabric density analysis mirror to complete
