Test method of tarpaulin

(one)
indirect test
This method is suitable for regular weave fabrics with high density and small yarn characteristics. First, after analyzing the fabric structure and the number of circular warp yarns
(Number of weft loops in weave), and then multiplied by the number of weave loops in 10cm, the product obtained is the warp (weft) yarn density.
(two)
direct measurement
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 5cm. Under the analysis lens, a long glass piece is engraved with a red line. When analyzing the fabric density, move the lens and align the red line on the glass piece and the red line on the scale at the same time. Between the yarns, take this as the starting point, and count the yarns while moving the lens until the 5cm scale line is this. The number of output yarns is multiplied by 2, which is the density value of 10cm fabric.
When counting the number of yarns, the center between the two yarns should be taken as the starting point. If the count reaches the end point, it exceeds 0.5, and when it is less than one, it should be counted as 0.75.
If it is less than 0.5, it will be counted as 0.25. Generally, 3-4 data should be measured for fabric density, and then the arithmetic mean value should be taken as the measurement result.
3. Weight:
Gram weight:
Refers to the weight in grams of one square meter of fabric.
Woven tarpaulin fabrics use "ounces", "an" or "OZ". Knitted tarpaulins generally use gram weight (g/m2).
28.35 grams, which is related to the yarn count and the weft and warp density of the fabric. The thicker the yarn, the thicker the cloth, and the greater the gram weight.
