Knowledge Of The Fabric About The Canvas Bags
The use of plain weave woven canvas, two by two or more yarns perpendicular to latitude and longitude 90 degree angle for woven fabrics, yarn called the warp vertical chanel sunglasses, horizontal yarns called weft. Both warp and weft strands of coarse with thick cotton or linen fabric, used sails for the first name. Canvas and fine canvas is usually divided into two categories canvas. Canvas canopy cover gucci outlet online, also known as cloth, used 58 (10) 4 to 7 strands woven system, fabric winding resistance adidas outlet, fastness, good water resistance, for motor transport, open storage of cover cloth and tent cloth, and other field . Fine canvas weft yarn is 2 shares 58 6 shares 28 (10 / 2 21 / 6), protective clothing and supplies for the work. After dyeing the fabric is also used as shoes, nonwoven bags travel bags, backpacks and canvas box materials.
Canvas with yarn that is typically British: one pound (454 grams) weight yarn (yarn or other ingredients), a length of 840 yards (0.9144 yards / meters), the fineness of a yarn. If one pound yarn, its length is 10x840 yards, and its fineness is 10, that symbol is letters S. Such as 10 yarn that is 10S, said strand is: 10 strands (two interactive and twist) for both: 10S / 2,21 branch 3 and twist for both: 21S / 3.
Canvas fabric density unit in metric terms, is 10CM arranged within the root of the number of warp and weft. Density, size, fabric directly affect the look, feel, thickness, strength, fracture resistance, air permeability, thermal properties such as wear resistance and mechanical indicators, and he is also related to the product cost and size of production efficiency.
An ounce usually canvas fabric or OZ as a unit, such as 6 An 8 An 10 An 12 An 14 An 16 An 18 An 22 An 24 An, is one square meter of fabric weight. Its conversion is 1 ounce equals 28.375 grams, the weight of yarn and fabric with warp and weft density, the greater the density the more coarse yarn thicker cloth, gram weight greater.
Canvas width:
Width, refer to the zonal width of the canvas in the international common-inch or said, rpet bag as 47. Cm or CM in the country often said gucci watches for men, such as 120cm. Inches and centimeters conversion formula: 1 inch = 2.54 cm. Such as: 36 equal 91.44CM, 47 is equal to 119.38CM, 63 is equal to 160.02CM.
Canvas classics, weft density measurement following two methods:
(A) the number of direct measurement method
With direct measurement method is according to the number of cloth or fabric density analysis mirror mirror to complete. Analysis of fabric density scale length mirror 5cm, the lens in the analysis below, a long strip of glass engraved with a red line, in the analysis of the fabric density, moving the lens, the glass on the red line and red line on the scale while between a quasi-two yarns, as a starting point, while moving the camera while a few number of yarn root, until 5cm scale line for this. Root of the number of yarn output multiplied by 2, that is, 10cm fabric density.
Number of roots in the points when the yarn to the center between the two yarns as a starting point, if the number to the finish line, more than 0.5, while less than one, the count should be 0.75; if less than 0.5, then count by 0.25. Fabric density should generally be measured 3-4 data, and then take the arithmetic average of measured results.
(Ii) indirect test method
This method is suitable for large density, yarn number of special rules for the organization of small fabric. After a first analysis of the organization and its organizational fabric warp cycle number (the number of weft loops Organization), recycled PET reusable bags and then multiplied by the number of 10cm in tissue cycle, the product is obtained by (weft) yarn density.
Woven canvas is more than two or two perpendicular yarn, latitude and longitude 90 degree angle for woven fabrics, woven by warp and weft where some bending, and Di in the direction perpendicular to the fabric plane bending , the degree of bending and tension between the warp and weft, and the stiffness of the yarn, woven fabrics to external tension when, as in the longitudinal tension, the yarn tension increases, the bending is reduced chanel watches, while the weft bending increases, non woven bag china such as vertical keep stretching until the warp completely straight up, while the fabric was transverse contraction. When the woven fabric to external tension to lateral tension, increase in weft tension, bending is reduced, while the increase in warp bending, recycle bag such as horizontal stretch non-stop until the weft completely straight up, while the fabric was a longitudinal contraction. The classics, weft conversion does not occur, and knits are different.
After due woven canvas, little weft extension and contraction, nor conversion occurs, so the fabric is generally more closely, and firm.
Physical and mechanical woven canvas, including the warp and weft yarn density, cloth sides, positive and negative, good times or bad hair direction, the fabric cover.
