Understand the direct measurement method of tarpaulin-News Center-Lin-Yang dishcloth factory
Understand the direct measurement method of tarpaulin and the direct measurement method of tarpaulin. Today we understand the algorithm of tarpaulin manufacturers.
As follows: 1. The direct measurement method is 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.
2. When counting the number of yarns, start with the center between the two yarns. If you count to the end, it will exceed 0. 5, and less than one, should press 0. 75 counts 3, if 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.
