Nain Rug
Nain rugs are constructed using the Persian knot and typically have between 300 and 700 knots per square inch. The pile is usually very high quality wool, clipped short, and silk is often used as highlighting for detail in the design.

Persian Knot
A knotted-pile carpet is a carpet containing raised surfaces, or piles, from the cut off ends of knots woven between the warp and weft. The Ghiordes/Turkish knot and the Senneh/Persian knot, typical of Anatolian carpets and Persian carpets, are the two primary knots.Goswami, K.K.; ed. (2009). ''Advances in Carpet Manufacture'', p.239. Woodhead Publishing in Textiles: Number 87 (The Textile Institute). . "The two most common types of knot used in an oriental carpet are the Persian knot and the Turkish knot." A flat or tapestry woven carpet, without pile, is a kilim. A pile carpet is influenced by width and number of warp and weft, pile height, knots used, and knot density. "The structural weft threads alternate with supplementary weft that rises from the surface of the weave at a perpendicular angle. This supplementary weft is attached to the warp by one of three knots... to form the pile or nap of the carpet." Knots are tied in rows, one to each pair of warp threads, which may t ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Square Inch
A square inch (plural: square inches) is a unit of area, equal to the area of a square with sides of one inch. The following symbols are used to denote square inches: *square in *sq inches, sq inch, sq in *inches/-2, inch/-2, in/-2 *inches^2, inch^2, in^2 *inches2, inch2, in2 (also denoted by "2) *historic engineering drawings □″ (number with a square & a double apostrophe, both as an exponent) The square inch is a common unit of measurement in the United States and the United Kingdom. A common unit of pressure, pound per square inch (psi) is derived from this unit of area. Equivalence with other units of area 1 square inch (assuming an international inch) is equal to: (the overbars indicate repeating decimals) * square feet (1 square foot is equal to 144 square inches) * square yards (1 square yard is equal to 1,296 square inches) * square centimetres (1 square centimetre is equal to square inches) * square metre The square metre ( international spelling as used by ...

Wool
Wool is the textile fibre obtained from sheep and other mammals, especially goats, rabbits, and camelids. The term may also refer to inorganic materials, such as mineral wool and glass wool, that have properties similar to animal wool. As an animal fibre, wool consists of protein together with a small percentage of lipids. This makes it chemically quite distinct from cotton and other plant fibres, which are mainly cellulose. Characteristics Wool is produced by follicles which are small cells located in the skin. These follicles are located in the upper layer of the skin called the epidermis and push down into the second skin layer called the dermis as the wool fibers grow. Follicles can be classed as either primary or secondary follicles. Primary follicles produce three types of fiber: kemp, medullated fibers, and true wool fibers. Secondary follicles only produce true wool fibers. Medullated fibers share nearly identical characteristics to hair and are long but lack c ...

Silk
Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm ''Bombyx mori'' reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors. Silk is produced by several insects; but, generally, only the silk of moth caterpillars has been used for textile manufacturing. There has been some research into other types of silk, which differ at the molecular level. Silk is mainly produced by the larvae of insects undergoing complete metamorphosis, but some insects, such as webspinners and raspy crickets, produce silk throughout their lives. Silk production also occurs in hymenoptera ( bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knots Per Sq Cm
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.
