The width of the reed sets the maximum width of the warp. [4] Common reed sizes for the hand-weaver are 6, 8, 10, 12, or 15 dents per inch, although sizes between 5 and 24 are not uncommon. [9] A reed with a larger number of dents per inch is generally used to weave finer fabric with a larger number of ends per inch. Because it is used to beat ...
The most obvious is the moving reed, the frames which hold the heddles and the "pinch" or "sand" roll utilized to keep the cloth tight as it passes over the front of the machine and onto the doff roll. The most common injury in weaving is pinched fingers from distracted or bored workers, though this is not the only such injury found.
Textile manufacturing is one of the oldest human activities. The oldest known textiles date back to about 5000 B.C. In order to make textiles, the first requirement is a source of fibre from which a yarn can be made, primarily by spinning.
Warp and weft in plain weaving A satin weave, common for silk, in which each warp thread floats over 15 weft threads A 3/1 twill, as used in denim. Weaving is a method of textile production in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth.
Loom beaters typically take the form of a bar mounted across the loom. The actual beating is done by a metal insert known as a reed, which contains a number of slots, known as dents, which the warp threads pass through. This is the more common form, as floor looms and mechanized looms both use a beater with a reed.
Three heddle-rods for weaving twill. The warp-weighted loom is a simple and ancient form of loom in which the warp yarns hang freely from a bar, which is supported by upright poles which can be placed at a convenient slant against a wall. Bundles of warp threads are tied to hanging weights called loom weights which keep the threads taut. [1]
To get a better shed the weaver can lift the harnesses while the reed is against the fabric, [1] [5] or raise only one harness at a time. By weaving in a different manner sometimes a good shed can be created. [5] The weaver can also insert a stick into the shed to clear it, and make way for the shuttle though this option is time-consuming.
The machinery used in fluid-jet weaving consists of a main nozzle, auxiliary nozzles or relay nozzles, and a profile reed. Air-jet looms are capable of producing standard household and apparel fabrics for items such as shirts, denim, sheets, towels, and sports apparel, as well as industrial products such as printed circuit board cloths.
