Knot Density
Knot density is a traditional measure for quality of handmade or knotted pile carpets. It refers to the number of knots, or knot count, per unit of surface area - typically either per square inch (kpsi) or per square centimeter (kpsc), but also per decimeter or meter (kpsd or kpsm). Number of knots per unit area is directly proportional to the quality of carpet.Cucker, Felipe (2013). ''Manifold Mirrors: The Crossing Paths of the Arts and Mathematics'', p.89-90. Cambridge University. . "The knot density...not only provides a measure of the work required to produce a given rug but also sets limits to the possible designs." Density may vary from or higher, where ≤80 kpsi is poor quality, 120 to 330 kpsi is medium to good, and ≥330 kpsi is very good quality. The inverse, knot ratio, is also used to compare characteristics. Knot density = warp×weft while knot ratio = warp/weft. For comparison: 100,000/square meter = 1,000/square decimeter = 65/square inch = 179/''gereh''. For ...

Pile (textile)
Pile is the raised surface or nap of a fabric, consisting of upright loops or strands of yarn."Pile." ''The Oxford English Dictionary''. 2nd ed. 1989. Examples of pile textiles are carpets, corduroy, velvet, plush, and Turkish towels. The word is derived from Latin ''pilus'' for "hair".Pile

Length and density

The surface and the yarn in these fabrics are also called "pile". In particular "pile length" or "pile depth" refer to the length of the yarn strands (half-length of the loops). Pile length affects and is affected by

Thread Count
Textile fibers, threads, yarns and fabrics are measured in a multiplicity of units. * A fiber, a single filament of natural material, such as cotton, linen or wool, or artificial material such as nylon, polyester, metal or mineral fiber, or man-made cellulosic fibre like viscose, Modal, Lyocell or other rayon fiber is measured in terms of linear mass density, the weight of a given length of fiber. Various units are used to refer to the measurement of a fiber, such as: the denier and tex (linear mass density of fibers), super S (fineness of wool fiber), worsted count, woolen count, linen count (wet spun) (or Number English (Ne)), cotton count (or Number English (Ne)), Number metric (Nm) and yield (the reciprocal of denier and tex). * A yarn, a spun agglomeration of fibers used for knitting, weaving or sewing, is measured in terms of cotton count and yarn density. * Thread, usually consisting of multiple yarns plied together producing a long, thin strand used in sewing or weavi ...

Knot (wood)
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or woodchips or fiber. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the production ...

Prayer Rug
A prayer rug or prayer mat is a piece of fabric, sometimes a pile carpet, used by Muslims, some Christians and some Baha'i during prayer. In Islam, a prayer mat is placed between the ground and the worshipper for cleanliness during the various positions of Islamic prayer. These involve prostration and sitting on the ground. A Muslim must perform (ablution) before prayer, and must pray in a clean place. Prayer rugs are also used by some Oriental Orthodox Christians for Christian prayer involving prostrations in the name of the Trinity, as well as during the recitation of the Alleluia and Kyrie eleison. Its purpose is to maintain a cleanly space to pray to God and shoes must be removed when using the prayer rug. Among Russian Orthodox Old Ritualists, a special prayer rug known as the Podruchnik is used to keep one's face and hands clean during prostrations, as these parts of the body are used to make the sign of the cross. Many new prayer mats are manufactured by weavers in a ...

Metropolitan Museum Of Art
The Metropolitan Museum of Art of New York City, colloquially "the Met", is the largest art museum in the Americas. Its permanent collection contains over two million works, divided among 17 curatorial departments. The main building at 1000 Fifth Avenue, along the Museum Mile on the eastern edge of Central Park on Manhattan's Upper East Side, is by area one of the world's largest art museums. The first portion of the approximately building was built in 1880. A much smaller second location, The Cloisters at Fort Tryon Park in Upper Manhattan, contains an extensive collection of art, architecture, and artifacts from medieval Europe. The Metropolitan Museum of Art was founded in 1870 with its mission to bring art and art education to the American people. The museum's permanent collection consists of works of art from classical antiquity and ancient Egypt, paintings, and sculptures from nearly all the European masters, and an extensive collection of American and modern ...

Ardabil Carpet
The Ardabil Carpet (or Ardebil Carpet) is the name of two different famous Persian carpets, the largest and best-known now in the Victoria and Albert Museum in London. Originally there were two presumably identical carpets, and the London carpet, as restored and reconstructed in the 19th century, uses sections from both. It now measures . The other carpet, now in the Los Angeles County Museum of Art, and smaller at , was made up of the sections in adequate condition unused for the London carpet. Both carpets are now smaller (shorter in particular) than they would have been originally, and there are other fragments in various collections that appear to come from the reconstruction process. The carpets have a typical Tabriz design, with one central medallion and smaller, ornate designs surrounding. Such medallions and shapes were central to the design and reality of Persian gardens, a common symbol of paradise for followers of Islam. A cartouche on the London carpet contains the ...

Pazyryk Carpet
The Pazyryk burials are a number of Scythian (Saka) "The rich kurgan burials in Pazyryk, Siberia probably were those of Saka chieftains" "Analysis of the clothing, which has analogies in the complex of Saka clothes, particularly in Pazyryk, led Wang Binghua (1987, 42) to the conclusion that they are related to the Saka Culture." "The dress of Iranian-speaking Saka and Scythians is easily reconstructed on the basis of... numerous archaeological discoveries from the Ukraine to the Altai, particularly at Issyk in Kazakhstan... at Pazyryk... and Ak-Alakha" Iron Age tombs found in the Pazyryk Valley and the Ukok plateau in the Altai Mountains, Siberia, south of the modern city of Novosibirsk, Russia; the site is close to the borders with China, Kazakhstan and Mongolia. Numerous comparable burials have been found in neighbouring western Mongolia. The tombs are Scythian-type kurgans, barrow-like tomb mounds containing wooden chambers covered over by large cairns of boulders and sto ...

Weaving
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 a ...

Warp And Woof
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. ''Warp'' means "that which is thrown away" (O ...
