A new rug 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 polyesterand 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. Rugs 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. Most of new rugs are hand made in Iran (known as Persian rug) , Turkey , Pakistan , India , Egypt ,Morocco , Afghanistan and Armenia.
