canvas fabric texture more and more, most of them are very delicate and smooth printing and imaging are very good. Relatively easy cleaning, after washing, will be a little modification, because the cotton will shrink. This is much stronger than the non-woven fabric. Canvas: one kind of thick cotton or linen. Originally named sail. Generally used plain weave, twill weave a small amount of the warp and weft yarns. Canvas is usually divided into two categories: rough canvas and fine canvas. Also referred to as canvas tarpaulins, usually 58 (10A) 4-7 from a woven fabric, folded quickly, good waterproof performance, and for automotive transportation field open warehouse, and tents. Fine canvas the warp and weft are usually 2 shares, stocks 58-6, 28 pounds (10 pounds / 21 pounds), for the production of labor protection clothing and articles. After staining, it can also be used as shoes, bag, backpack, and other fabrics. In addition, rubber, canvas, fire, radiation canvas, canvas, and the like machine.

Hobo S: short yarn, it refers to the fineness of the yarn, Chinese current or "Empire": one lb (454 grams) of the yarn (wire or another component), a length of 840 yards (0.9144 yards / m), a yarn fineness. Canvas Density: Cotton fabric density calculation unit metric units, the finger 10 cm of warp and weft yarns are arranged. Density directly affects the size of the fabric appearance, feel, thickness, strength, crack resistance, air permeability, abrasion resistance, thermal properties, and other physical and mechanical indicators, but also the product cost and production efficiency related.
Direct measurement and by direct measurement of the cloth or fabric density analyzer completed. Analysis mirror fabric density scale length is 5 cm, the analysis under the lens, a rectangular piece of glass engraved red analysis of the fabric density, moving the camera, the size of a piece of glass between the two lines in the red, while the red line, as a origin, while the number of yarns lens movement amount, up to 5 cm cord. the number of yarns in the output multiplied by 2, i.e. the density of the fabric 10cm. To calculate the number of yarns, the yarns should be the center between the two is the starting point. If you count the end of this line is more than 0.5 points and less than 1, you should press 0.75; is less than 0.5, then the number of 0.25. Fabric density usually uses to measure the number of 3-4, then it is the arithmetic average of the measurement results.

Indirect test. This method is applicable to the general fabric having a high density and small yarns. First, after the fabric structure and organization analyzed warp (equatorial stitch number), multiplied by the number of cycles of 10 cm, resulting in warp yarns (weft) yarn density. HobuKeshige: g body weight: Refers to one square meter of fabric weight grams. Woven canvas cloth and "oz" "security" or "OZ" is a commonly used knitting canvas weight (g / m2) conversion of 1 ounce = 28.375 g, but usually in the machine cloth 28.35 g, yarn and fabric density, yarn density thicker cloth thicker, a large weight. Fabric and yarn density, do not mind, but uses a relatively thick ounce fabric, such as denim canvas ounce must be, in fact, you can also be understood as a relatively rough and Oz yarn, but it is now widely used in denim and canvas.
