    The term carpet comes from Old French carpite. One derivation of the term states that the French term came from the Old Italian carpita, from the verb "carpire" meaning to pluck. The Online Etymology Dictionary states that the term "carpet" was first used in English in the late 13th century, with the meaning "coarse cloth", and by the mid-14th century, "tablecloth, [or] bedspread". The Online Etymology Dictionary states that the term comes "...from Old French carpite "heavy decorated cloth, carpet," from Medieval Latin or Old Italian carpita "thick woolen cloth," probably from Latin carpere "to card, pluck," probably so called because it was made from unraveled, shred[d]ed, "plucked" fabric".The meaning of the term "carpet" shifted in the 15th century to refer to floor coverings. The term "carpet" is often used interchangeably with the term "rug". Some sources define a carpet as stretching from wall to wall. Another definition treats rugs as of lower quality or of smaller size, with...

    Woven

    The carpet is produced on a loom quite similar to woven fabric. The pile can be plush or Berber. Plush carpet is a cut pileand Berber carpet is a loop pile. There are new styles of carpet combining the two styles called cut and loop carpeting. Normally many colored yarns are used and this process is capable of producing intricate patterns from predetermined designs (although some limitations apply to certain weaving methods with regard to accuracy of pattern within the carpet). These carpets...

    Needle felt

    These carpets are more technologically advanced. Needle felts are produced by intermingling and felting individual synthetic fibersusing barbed and forked needles forming an extremely durable carpet. These carpets are normally found in commercial settings such as hotels and restaurants where there is frequent traffic.

    Knotted

    On a knotted pile carpet (formally, a "supplementary weft cut-loop pile" carpet), the structural weft threads alternate with a supplementary weft that rises at right angles to the surface of the weave. This supplementary weft is attached to the warp by one of three knot types (see below), such as shag carpet which was popular in the 1970s, to form the pile or nap of the carpet. Knotting by hand is most prevalent in oriental rugs and carpets. Kashmir carpets are also hand-knotted. Pile carpets...

    Carpet can be formulated from many single or blended natural and synthetic fibres. Fibres are chosen for durability, appearance, ease of manufacture, and cost. In terms of scale of production, the dominant yarn constructions are polyamides (nylons) and polypropylene with an estimated 90% of the commercial market.

    The knotted pile carpet probably originated in the Caspian Sea area (Northern Iran) or the Armenian Highland. Although there is evidence of goats and sheep being sheared for wool and hair which was spun and woven as far back at the 7th millennium, the earliest surviving pile carpet is the "Pazyryk carpet", which dates from the 5th-4th century BC. It was excavated by Sergei Ivanovich Rudenko in 1949 from a Pazyryk burial mound in the Altai Mountains in Siberia. This richly coloured carpet is 200 x 183 cm (6'6" x 6'0") and framed by a border of griffins. Although claimed by many cultures, this square tufted carpet, almost perfectly intact, is considered by many experts to be of Caucasian, specifically Armenian, origin. The rug is woven using the Armenian double knot, and the red filaments' color was made from Armenian cochineal. The eminent authority of ancient carpets, Ulrich Schurmann, says of it, "From all the evidence available I am convinced that the Pazyryk rug was a funeral acc...

    Carpet is commonly made in widths of 12 feet (3.7 m) and 15 feet (4.6 m) in the US, 4 m and 5 m in Europe. Where necessary different widths can be seamed together with a seaming iron and seam tape (formerly it was sewn together) and it is fixed to a floor over a cushioned underlay (pad) using nails, tack strips (known in the UK as gripper rods), adhesives, or occasionally decorative metal stair rods, thus distinguishing it from rugs or mats, which are loose-laid floor coverings. For environmental reasons, the use of wool, natural bindings, natural padding, and formaldehyde-free glues is becoming more common. These options are almost always at a premium cost. In the UK, some carpets are still manufactured for yachts, hotels, pubs and clubs in a narrow width of 27 inches (0.69 m) and then sewn to size. Carpeting which covers an entire room area is loosely referred to as 'wall-to-wall', but carpet can be installed over any portion thereof with use of appropriate transition moldings whe...

    For the year 2018 in the U.S., the recycling of carpet fiber, backing, and padding was 310,000 tons, which was 9.2 percent of carpet generation. A slightly larger proportion (17.8 percent) was combusted for energy recovery, while the majority of rugs and carpets were landfilled (73 percent).

    There are many stories about magic carpets, legendary flying carpets that can be used to transport people who are on it instantaneously or quickly to their destination. Disney's Aladdin depicts a magic carpet found by Aladdin and Abu in the Cave of Wonders while trying to find Genie's lamp. Aladdin and Jasmine ride on him to go on a ride around the world. The term "[m]agic carpet [is] first attested [in] 1816. From the 16th century to the 19th century, the term "carpet" was used "...as an adjective often with a tinge of contempt, when used of men (as in carpet-knight, 1570s)", which meant a man who was associated with "...luxury, ladies' boudoirs, and drawing rooms". Rolling out the red carpet is an expression which means to welcome a guest lavishly and handsomely. In some cases, an actual red carpet is used for VIPs and celebrities to walk on, such as at the Cannes Film Festivaland when foreign dignitaries are welcomed to a country. In 1820s British servant slang, to "carpet" someo...
