Testing method of tarpaulin quality

Some people may not know very well about tarpaulins. They don't know what tarpaulins are or what tarpaulins are. Today, Linyi tarpaulin factory will share with you: a thicker cotton fabric or linen fabric. Named for its original use for sails. Generally, plain weave is used, a small amount of twill weave is used, and multi-strand threads are used for warp and weft yarns. Classification of tarpaulins: tarpaulins are usually divided into two categories: coarse tarpaulins and fine tarpaulins. Coarse tarpaulin, also known as tarpaulin, is a fabric that is strong and resistant to folding and has good waterproof performance. The warp and weft yarns of fine tarpaulin are used in the production of labor protection clothing and its supplies. After dyeing, it can also be used as shoes, travel bags, backpacks and other fabrics. In addition, there are rubber tarpaulins, shielding tarpaulins for fire and radiation protection, and tarpaulins for paper machines. 1. Yarn count: In short, yarn count refers to the thickness of the yarn. Currently, the 'Imperial system' is still commonly used in China, that is: one pound (454 grams) of cotton yarn (or other component yarns) with a length of 840 yards (0.9144 yards/meter), the fineness of the yarn is one. If a pound of yarn, its length is 10 × 840 yards, its fineness is 10 counts, the representation method of yarn counts is the English letter 'S', and the representation method of single yarn is: 32 single yarns -- ----- Represented as: 32S strands are expressed as: 32 strands (two twisted) are: 32S/2, 42 3 strands are twisted: 42S/3. 2. Density: The calculation unit of tarpaulin fabric density is in metric system, which refers to the number of warp and weft yarns arranged within 10cm. The size of the density directly affects the physical and mechanical indicators such as the appearance, feel, thickness, strength, folding resistance, air permeability, abrasion resistance and thermal insulation performance of the fabric, and it is also related to the cost and production efficiency of the product. (1) Indirect test method This method is suitable for fabrics with high density and small yarn characteristics. First, after analyzing the fabric structure and the number of weave loops (the number of weft loops), and then multiplying the number of weave loops in 10cm, the product obtained is the warp (weft) yarn density. (2) Direct measurement method 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, take the center between the two yarns as the starting point. If the count reaches the end, 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, then 0.25 root count. Generally, 3-4 data should be measured for fabric density, and then the arithmetic mean value should be taken as the measurement result. 3. Gram 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). It is related to the warp and weft density of the fabric. The thicker the yarn, the thicker the cloth and the greater the gram weight.
