Carpet

A carpet is a textile floor covering consisting of an upper layer of pile attached to a backing. The pile is generally either made from wool or fibers such as polypropylene, nylon or polyester and usually consists of twisted tufts which are often heat-treated to maintain their structure. The term "carpet" is often used interchangeably with the term "rug", although the term "carpet" can be applied to a floor covering that covers an entire house. Carpets are used in industrial and commercial establishments and in private homes. Carpets are used for a variety of purposes, including insulating a person's feet from a cold tile or concrete floor, making a room more comfortable as a place to sit on the floor (e.g., when playing with children or praying in Arabic culture) and adding decoration or colour to a room.

Carpets can be produced on a loom quite similar to woven fabric, made using needle felts, knotted by hand (in oriental rugs), made with their pile injected into a backing material (called tufting), flatwoven, made by hooking wool or cotton through the meshes of a sturdy fabric or embroidered. Carpet is commonly made in widths of 12 feet (3.7 m) and 15 feet (4.6 m) in the USA, 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.

Red carpet

A red carpet is traditionally used to mark the route taken by heads of state on ceremonial and formal occasions, and has in recent decades been extended to use by VIPs and celebrities at formal events.

History

The earliest known reference to walking a red carpet in literature is in the play Agamemnon by Aeschylus, written in 458 BC. When the title character returns from Troy, he is greeted by his vengeful wife Clytemnestra who offers him a red path to walk upon:

Agamemnon, knowing that only gods walk on such luxury, responds with trepidation:

Oriental carpets in Renaissance painting often show rugs and carpets, patterned but with red often the main background colour, laid on the steps to a throne, or on a dais where rulers or sacred figures are placed.

A red carpet was rolled out to a river to welcome the arrival of United States president James Monroe in 1821. In 1902, The New York Central Railroad used plush crimson carpets to direct people as they boarded their 20th Century Limited passenger train. This is believed to be the origin of the phrase "red-carpet treatment". Film premieres are often laid down with red carpets.
