Curtains
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. A curtain is also the movable screen or drape in a theatre that separates the stage from the auditorium or that serves as a backdrop/background. 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, colours, and patterns. They often have their own sections within department stores, while some shops are completely dedicated to selling curtains. Curtains vary according to cleanability, ultraviolet light deterioration, oil and dust retention, noise absorption, fire res ...

Theater 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, 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 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 diagonally using lines ( ...

Ninon
Ninon is a lightweight, sheer fabric made with plain or leno weaving, it is a suitable material for curtains, evening wear and lingerie. Ninon is made with variety of filament yarns such as polyester, silk, rayon or nylon. History Ninon is a French derivation from the name Anne. Originally it was made from highly twisted silk yarns, gradually changed to synthetic yarns such as rayon. In the early 20th century (1909), the Ninon silk was in use for dresses also. Types Initially there were two types of Ninons, single and double. The difference was with the number of ply or the twisted yarns used in weaving: one, two, or three. The finest and single Ninons are more popular. Structure and characteristics Ninon is a lightweight sheer material with good draping qualities. It is very thin and has a surface with a mild sheen. Ninon has an open mesh-like appearance and a crisp hand feel. Ninon has more transparency similar to Marquisette in comparison to its peers such as voile, ...

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 french: porte. 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 ...

A Breeze In The Curtains
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it fro ...

Window Shutter
A window shutter is a solid and stable window covering usually consisting of a frame of vertical stiles and horizontal rails (top, centre and bottom). Set within this frame can be louvers (both operable or fixed, horizontal or vertical), solid panels, fabric, glass and almost any other item that can be mounted within a frame. Shutters may be employed for a variety of reasons, including controlling the amount of sunlight that enters a room, to provide privacy, security, to protect against weather or unwanted intrusion or damage and to enhance the aesthetics of a building. Depending on the application, and the construction of the window frame, shutters can be mounted to fit within the opening or to overlap the opening. The term window shutter includes both interior shutters, used on the inside of a house or building, and exterior shutters, used on the outside of a structure. On some styles of buildings it is common to have shutters to cover the doors as well as the windows. Inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opaque
Opacity or opaque may refer to: * Impediments to (especially, visible) light: ** Opacities, absorption coefficients ** Opacity (optics), property or degree of blocking the transmission of light * Metaphors derived from literal optics: ** In linguistics: *** Opaque context, a term to describe the linguistic context of co-referential terms *** Phonological opacity, a term in phonology *** Semantic opacity, the opposite of semantic transparency ** Opaque travel inventory, the market of selling unsold travel inventory at a discounted price * Musical works: ** ''Opacity'' (album) ** Opacities (EP) * Computer science: ** Measure of obscuration of background by "painting" an image, e.g. alpha channel ** Use of an opaque data type ** Property attributed to data that can be interpreted only by using an external entity, e.g. magic cookie In computing, a magic cookie, or just cookie for short, is a token or short packet of data passed between communicating programs. The cookie is often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Absorption (electromagnetic Radiation)
In physics, absorption of electromagnetic radiation is how matter (typically electrons bound in atoms) takes up a photon's energy — and so transforms electromagnetic energy into internal energy of the absorber (for example, thermal energy). A notable effect is attenuation, or the gradual reduction of the intensity of light waves as they propagate through a medium. Although the absorption of waves does not usually depend on their intensity (linear absorption), in certain conditions (optics) the medium's transparency changes by a factor that varies as a function of wave intensity, and saturable absorption (or nonlinear absorption) occurs. Quantifying absorption Many approaches can potentially quantify radiation absorption, with key examples following. * The absorption coefficient along with some closely related derived quantities * The attenuation coefficient (NB used infrequently with meaning synonymous with "absorption coefficient") * The Molar attenuation coefficient (a ...

Lace
Lace is a delicate fabric made of yarn or thread in an open weblike pattern, made by machine or by hand. Generally, lace is divided into two main categories, needlelace and bobbin lace, although there are other types of lace, such as knitted or crocheted lace. Other laces such as these are considered as a category of their specific craft. Knitted lace, therefore, is an example of knitting. This article considers both needle lace and bobbin lace. While some experts say both needle lace and bobbin lace began in Italy in the late 1500s, there are some questions regarding its origins. Originally linen, silk, gold, or silver threads were used. Now lace is often made with cotton thread, although linen and silk threads are still available. Manufactured lace may be made of synthetic fiber. A few modern artists make lace with a fine copper or silver wire instead of thread. Etymology The word lace is from Middle English, from Old French ''las'', noose, string, from Vulgar Latin *' ...

Marquisette
Marquisette is a lightweight, sheer fabric that has a structure similar to a mosquito net. Construction Marquisette is a very loose weave construction plain and sometimes with designs. Leno is one type of weaving the marquisette. Marquisette may be made with many natural or synthetic yarns, and the most common is nylon. The other variants are possible with cotton, silk, rayon, orlon and polyester. Use Marquisette is employed in certain undergarments, and is seen in dresses such as bridal wear and evening wear. It can commonly be seen in sheer draperies and curtains. See also * Ninon * Voile Voile is a soft, sheer fabric, usually made of 99% cotton or cotton blended with linen or polyester. The term is French for ''veil''. Because of its light weight, the fabric is mostly used in soft furnishing. In tropical climates, voile is used ...

Polyester
Polyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in plants and insects, as well as synthetics such as polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. Synthetic polyesters are used extensively in clothing. Polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties. Cotton-polyester blends can be strong, wrinkle- and tear-resistant, and reduce shrinking. Synthetic fibers using polyester have high water, wind and environmental resistance compared to plant-derived fibers. They are less Fireproofing, fire-resistant and can melt when ignited. Liquid crystalline polyesters are among the first industrially used liquid crystal polymers. They are use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Window With Transluscent Curtains
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. In addition to this, many modern day windows may have a window screen or mesh, often made of aluminum or fibreglass, to keep bugs out when the window is opened. 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, sideli ...
