Curtain
A curtain is a piece of cloth or other material intended to block or obscure light, air drafts, or (in the case of a shower curtain) water. Curtains are often hung on the inside of a building's windows to block the passage of light. For instance, at night to aid sleeping, or to stop light from escaping outside the building (stopping people outside from being able to see inside, often for privacy reasons). In this application, they are also known as ''draperies''. Curtains hung over a doorway are known as portières. Curtains come in a variety of shapes, materials, sizes, colors, and patterns. They often have their own sections within department stores, while some shops are completely dedicated to selling curtains. Theater drapes and stage curtains serve a number of sound-absorbing and light-blocking functions, such as the front curtain that separates the stage from the auditorium, and other curtains and drapes that serve as backdrops or to obscure offstage areas.

Front Curtain
A front curtain, also known as a (front-of-)house curtain, act curtain, grand drape, main curtain or drape, proscenium curtain, or main rag is the stage curtain or curtains at the very front of a theatrical Stage (theatre), stage, separating it from the house. The front curtain is usually opened at the beginning of a performance to reveal the stage set and closed for intermissions as well as the end of a performance. The most common material for the front curtain is a heavy velour material, often with pleated Pleat, fullness sewn into the fabric to create a more opulent appearance. Types There are several styles of house curtains, which vary in construction, operation, and cost. Depending on a curtain's type, its fabric may be flat or pleated, and it may drape, hang, or do both. Some types open with the full curtain rising out, either via a fly system or by gathering upwards with lines; other types part in the centre and either travel horizontally on a track or are pulled out d ...

Theater Drapes And Stage Curtains
Theater drapes and stage curtains are large pieces of cloth that are designed to mask backstage areas of a theater from spectators. They are designed for a variety of specific purposes, moving in different ways (if at all) and constructed from various fabrics. Many are made from black or other darkly colored, light-absorbing material (In North America, for example, heavyweight velour is the current industry standard). Theater drapes represent a portion of any production's ''soft goods'', a category comprising any non-wardrobe, cloth-based element of the stage or scenery. Theater curtains are often pocketed at the bottom to hold weighty chain or to accept pipes to remove their fullness and stretch them tight. Proscenium stages use a greater variety of drapes than arena or thrust stages. In proscenium theaters, drapes are typically suspended from battens and can be controlled by a fly system (i.e., they are "flown," in theater terminology). When a drape is flown, the task of adjust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curtain Tie-back
A curtain tie-back is a decorative window treatment which accompanies a cloth curtain. Within the field of interior decoration, tie-backs made of fabric are classified as a kind of "soft furnishing" (along with other fabric-based décor such as pillows, valances, towels, blankets, mattresses, bed skirts, bedspreads, jabots, and shower and window curtains) while those made out of wood, metal, or glass are considered "window hardware" (along with curtain rods, cornices, latches, hinges, push bars, and handles). Soft furnishing A simple rope or braid used to secure a curtain to one side of a window is a basic curtain tie-back. Other more elaborate soft furnishing curtain tie-backs usually fall into one of the following categories. Structured tie-back A structured tie-back consists of a single short U-shaped strip of fabric held flat by a piece of interfacing. A ring (often metal, sometimes wood or plastic) is placed at each end of the strip, and the strip is looped around the cur ...

Shower Curtain
A shower is a place in which a person bathes under a spray of typically warm or hot water. Indoors, there is a drain in the floor. Most showers are set up to have adjustable temperature, spray pressure and showerhead nozzle angle. The simplest showers have a swivelling nozzle aimed downward, while more complex showers have a showerhead connected to a hose that has a mounting bracket; this allows the showerer to hold the showerhead by hand to spray the water onto different parts of their body. A showerhead can be installed in a small shower stall, or bathtub, with a plastic shower curtain or door. Showering is common due to the efficiency of using it compared with using a bathtub. Its use in hygiene is, therefore, common practice. History Waterfalls have historically been used as primitive forms of showers. The falling water rinsed the bathers completely clean and was more efficient than bathing in a traditional basin, which required manual transport of both fresh and wast ...

Portière
A portière () is a hanging curtain placed over a door or over the doorless entrance to a room. Its name is derived from the word for door in . History From Asia, it came to Europe at a remote date. It is known to have been in use in Europe in the 4th century, and was probably introduced much earlier. Like so many other domestic plenishings, it reached England by way of France, where it appears to have been originally called ''rideau de Porte'' (literally, "door curtain"). Common in wealthier households during the Victorian era, it is still occasionally used either as an ornament or as a means of mitigating draughts. It is usually of some heavy material, such as velvet, brocade, or plush, and is often fixed upon a brass arm, moving in a socket with the opening and closing of the door. Rising portière A rising portière is a simple but effective mechanism. It is fastened to both the door and to the wall near the hinge, such that the rail raises itself when the door is opened. ...

Cloth
Textile is an umbrella term that includes various fiber-based materials, including fibers, yarns, filaments, threads, and different types of fabric. At first, the word "textiles" only referred to woven fabrics. However, weaving is not the only manufacturing method, and many other methods were later developed to form textile structures based on their intended use. Knitting and non-woven are other popular types of fabric manufacturing. In the contemporary world, textiles satisfy the material needs for versatile applications, from simple daily clothing to bulletproof jackets, spacesuits, and doctor's gowns. Textiles are divided into two groups: consumer textiles for domestic purposes and technical textiles. In consumer textiles, aesthetics and comfort are the most important factors, while in technical textiles, functional properties are the priority. The durability of textiles is an important property, with common cotton or blend garments (such as t-shirts) able to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Door
A door is a hinged or otherwise movable barrier that allows ingress (entry) into and egress (exit) from an enclosure. The created opening in the wall is a ''doorway'' or ''portal''. A door's essential and primary purpose is to provide security by controlling access to the doorway (portal). Conventionally, it is a panel that fits into the doorway of a building, room, or vehicle. Doors are generally made of a material suited to the door's task. They are commonly attached by hinges, but can move by other means, such as slides or counterbalancing. The door may be able to move in various ways (at angles away from the doorway/portal, by sliding on a plane parallel to the frame, by folding in angles on a parallel plane, or by spinning along an axis at the center of the frame) to allow or prevent ingress or egress. In most cases, a door's interior matches its exterior side. But in other cases (e.g., a vehicle door) the two sides are radically different. Many doors incorporate lock ...

Window
A window is an opening in a wall, door, roof, or vehicle that allows the exchange of light and may also allow the passage of sound and sometimes air. Modern windows are usually glazed or covered in some other transparent or translucent material, a sash set in a frame in the opening; the sash and frame are also referred to as a window. Many glazed windows may be opened, to allow ventilation, or closed to exclude inclement weather. Windows may have a latch or similar mechanism to lock the window shut or to hold it open by various amounts. Types include the eyebrow window, fixed windows, hexagonal windows, single-hung, and double-hung sash windows, horizontal sliding sash windows, casement windows, awning windows, hopper windows, tilt, and slide windows (often door-sized), tilt and turn windows, transom windows, sidelight windows, jalousie or louvered windows, clerestory windows, lancet windows, skylights, roof windows, roof lanterns, bay windows, oriel windows, ...

Absorption (acoustics)
In acoustics, absorption refers to the process by which a material, structure, or object takes in sound energy when sound, sound waves are encountered, as opposed to reflection (physics), reflecting the energy. Part of the absorbed energy is transformed into heat and part is transmitted through the absorbing body. The energy transformed into heat is said to have been 'Dissipation, lost'.Acoustic Absorbers and Diffusers: Theory, Design and Applicatio.CRC Press .2009.Peter D'Antoni When sound from a loudspeaker collides with the walls of a room, part of the sound's energy is reflection (physics), reflected back into the room, part is transmitted through the walls, and part is absorbed into the walls. Just as the acoustic energy was transmitted through the air as pressure differentials (or deformations), the acoustic energy travels through the material which makes up the wall in the same manner. Deformation causes mechanical losses via conversion of part of the sound energy into h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saqaliba
Saqaliba (, singular ) is a term used in medieval Arabic sources to refer to Slavs, and other peoples of Central, Southern, and Eastern Europe. The term originates from the Middle Greek '' slavos/sklavenos'' (Slav), which in Hispano-Arabic came to designate Slavic slaves. The word was often used to refer specifically to Slavic slaves, but it could also refer more broadly to various other ethnicities of Eastern Europe traded by the Arab traders, as well as all European slaves in some Muslim regions like Spain and Portugal including those abducted from raids on Christian kingdoms of Spain and Portugal.Historical Encyclopedia of World Slavery saqaliba&f=false The Historical Encyclopedia of World Slavery: A-K; ...

Mamluk
Mamluk or Mamaluk (; (singular), , ''mamālīk'' (plural); translated as "one who is owned", meaning "slave") were non-Arab, ethnically diverse (mostly Turkic, Caucasian, Eastern and Southeastern European) enslaved mercenaries, slave-soldiers, and freed slaves who were assigned high-ranking military and administrative duties, serving the ruling Arab and Ottoman dynasties in the Muslim world. The most enduring Mamluk realm was the knightly military class in medieval Egypt, which developed from the ranks of slave-soldiers. Originally the Mamluks were slaves of Turkic origins from the Eurasian Steppe, but the institution of military slavery spread to include Circassians, Abkhazians, Georgians, Armenians, Russians, and Hungarians, as well as peoples from the Balkans such as Albanians, Greeks, and South Slavs (''see'' Saqaliba). They also recruited from the Egyptians. The "Mamluk/Ghulam Phenomenon", as David Ayalon dubbed the creation of the specific warrior class, was ...
