Air-jet Loom
An air-jet loom is a shuttleless loom that uses a jet of air to propel the weft yarn through the warp shed. It is one of two types of fluid-jet looms, the other being a water-jet loom, which was developed previously. Fluid-jet looms can operate at a faster speed than predecessor looms such as rapier looms, but they are not as common. 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. Heavier yarns are more suitable for air-jet looms than lighter yarns. Air-jet looms are capable of weaving plaids, as well as dobby and jacquard fabrics. Method In an air-jet loom, yarn is pulled from the supply package, and the measuring disc removes a length of yarn of the width of fabric being woven. A clamp ho ...

Loom
A loom is a device used to weave cloth and tapestry. The basic purpose of any loom is to hold the warp threads under tension to facilitate the interweaving of the weft threads. The precise shape of the loom and its mechanics may vary, but the basic function is the same. Etymology and usage The word "loom" derives from the Old English ''geloma'', formed from ''ge-'' (perfective prefix) and ''loma'', a root of unknown origin; the whole word ''geloma'' meant a utensil, tool, or machine of any kind. In 1404 "lome" was used to mean a machine to enable weaving thread into cloth. By 1838 "loom" had gained the additional meaning of a machine for interlacing thread. Weaving Weaving is done by intersecting the longitudinal threads, the warp, i.e. "that which is thrown across", with the transverse threads, the weft, i.e. "that which is woven". The major components of the loom are the warp beam, heddles, harnesses or shafts (as few as two, four is common, sixteen not unheard of), s ...

Weft
Warp and weft are the two basic components used in weaving to turn thread or yarn into fabric. The lengthwise or longitudinal warp yarns are held stationary in tension on a frame or loom while the transverse weft (sometimes woof) is drawn through and inserted over and under the warp. A single thread of the weft crossing the warp is called a ''pick''. Terms vary (for instance, in North America, the weft is sometimes referred to as the ''fill'' or the ''filling yarn'').Barber (1991), p. 79 Each individual warp thread in a fabric is called a ''warp end'' or ''end''.Burnham (1980), pp. 170, 179 Inventions during the 18th century spurred the Industrial Revolution, with the "picking stick" and the " flying shuttle" ( John Kay, 1733) speeding up the production of cloth. The power loom patented by Edmund Cartwright in 1785 allowed sixty picks per minute. Etymology The word ''weft'' derives from the Old English word ''wefan'', to weave.

Rapier Loom
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. 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. The other end of the rapier is connected to the control system. The rapier moves across the width of the fabric, carrying the weft yarn across through the shed to the opposite side. The rapier is then retracted, leaving the new pick in place. In some versions of the loom, two rapiers are used, each half the width of the fabric in size. One rapier carries the yarn to the centre of the shed, where the opposing rapier picks up the yarn and carries it the remainder of the way across the shed. The double rapier is used more frequently than the single rapier due to its increased pick insertion speed and ability to weave wider widths of fabric. The housing f ...

Nozzle
A nozzle is a device designed to control the direction or characteristics of a fluid flow (specially to increase velocity) as it exits (or enters) an enclosed chamber or pipe. A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas). Nozzles are frequently used to control the rate of flow, speed, direction, mass, shape, and/or the pressure of the stream that emerges from them. In a nozzle, the velocity of fluid increases at the expense of its pressure energy. Types Jet A gas jet, fluid jet, or hydro jet is a nozzle intended to eject gas or fluid in a coherent stream into a surrounding medium. Gas jets are commonly found in gas stoves, ovens, or barbecues. Gas jets were commonly used for light before the development of electric light. Other types of fluid jets are found in carburetors, where smooth calibrated orifices are used to regulate the flow of fuel into an engine, and in jacuzzis or spa ...

Reed (weaving)
A reed is part of a weaving loom, and resembles a comb. It is used to separate and space the warp threads, to guide the shuttle's motion across the loom, and to push the weft threads into place."Reed." ''The Oxford English Dictionary''. 2nd ed. 1989.1911 Encyclopædia Britannica The reed is securely held by the beater, and consists of a frame with many vertical slits. Floor looms and mechanized looms both use a beater with a reed, whereas Inkle weaving and tablet weaving do not use reeds. History Modern reeds are made by placing flattened strips of wire (made of carbon or stainless steel) between two half round ribs of wood, and binding the whole together with tarred string. Historically, reeds were made of reed or split cane. The split cane was then bound between ribs of wood in the same manner as wire is now. In 1738, John Kay replaced split cane with flattened iron or brass wire, and the change was quickly adopted. To make a reed, wire is flattened to a uniform thickn ...

Weaving Equipment
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. Other methods are knitting, crocheting, felting, and braiding or plaiting. The longitudinal threads are called the warp and the lateral threads are the weft, woof, or filling. (''Weft'' is an Old English word meaning "that which is woven"; compare ''leave'' and ''left''.) The method in which these threads are interwoven affects the characteristics of the cloth. Cloth is usually woven on a loom, a device that holds the warp threads in place while filling threads are woven through them. A fabric band that meets this definition of cloth (warp threads with a weft thread winding between) can also be made using other methods, including tablet weaving, back strap loom, or other techniques that can be done without looms. The way the warp and filling threads interlace with each other is called the weave. The majority of woven products ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas Technologies
Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture, such as air, contains a variety of pure gases. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. This separation usually makes a colourless gas invisible to the human observer. The gaseous state of matter occurs between the liquid and plasma states, the latter of which provides the upper temperature boundary for gases. Bounding the lower end of the temperature scale lie degenerative quantum gases which are gaining increasing attention. High-density atomic gases super-cooled to very low temperatures are classified by their statistical behavior as either Bose gases or Fermi gases. For a comprehensive listi ...
