How to test the density of tarpaulin determines the waterproof and service life of tarpaulin. How do we detect the density of tarpaulin when selecting tarpaulin? The tarpaulin factory will teach you how to test the density of tarpaulin. The calculation unit of fabric density in tarpaulin is metric, which refers to the number of warp and weft yarns arranged. When testing the density of tarpaulin, if it is roughly estimated that the tarpaulin has a high density, a small number of yarns, and a regular structure, an indirect test method can be used: firstly, the number of circulating yarns of the fabric tissue and its tissue is analyzed (Number of tissue circulating weft yarns) , And then multiply by the number of tissue cycles in, and the product obtained is warp (Weft)Yarn density. If it does not belong to the above-mentioned tarpaulin type, Linyi tarpaulin factory will adopt the direct measurement method: it will be completed by means of a cloth mirror or a fabric density analysis mirror. The length of the scale of the fabric density analysis mirror is 5 cm. Under the analysis lens, a long piece of glass is engraved with a red line. When analyzing the fabric density, the lens is moved, align the red line on the glass sheet and the red line on the scale at the same time between a certain two yarns, starting from which the number of yarns is counted while moving the lens until the 5cm scale line is used for this. The output yarn number multiplied by 2 is the density value of fabric. When counting the number of yarns, start with the center between the two yarns, and if you count to the end, exceed 0. 5, and less than one, should press 0. 75 calculations; If it is less than 0. When 5, press 0. 25 calculations. Fabric density should generally be measured 3- 4 Data, and then take its arithmetic average as the measurement result.
