The purpose of introducing size, which is either a starchy substance for cotton or gelatinous mixture for woollen fibre, is to reduce the chances of threads fraying and breaking due to the friction of the weaving process. [1] The size stiffens the thread and helps the fibres lie closely together. [2] Many recipes for size can be found in ...
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]

Weaving a tapestry on a vertical loom in Konya, Turkey A Turkish carpet loom showing warp threads wrapped around the warp beam, above, and the fell being wrapped onto the cloth beam below. A simple handheld frame loom. Weaving is done on two sets of threads or yarns, which cross one ...
It is the "Jacquard head" that adapts to a great many dobby looms that allow the weaving machine to then create the intricate patterns often seen in Jacquard weaving. Jacquard-driven looms, although relatively common in the textile industry, are not as ubiquitous as dobby looms which are usually faster and much cheaper to operate.
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.
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.

Sizing or size is a substance that is applied to, or incorporated into, other materials—especially papers and textiles—to act as a protective filler or glaze. Sizing is used in papermaking and textile manufacturing to change the absorption and wear characteristics of those materials.
A rapier loom is a shuttleless weaving loom in which the filling yarn is carried through the shed of warp yarns to the other side of the loom by finger-like carriers called rapiers. [1] A stationary package of yarn is used to supply the weft yarns in the rapier machine. One end of a rapier, a rod or steel tape, carries the weft yarn.
