Bell Twist carpet

A carpet is any loom-woven, felted textile or grass floor covering. The term was also used for table and wall coverings, as carpets were not commonly used on the floor in European interiors until the 18th century. The hand-knotted pile carpet probably originated in Central Asia between the 3rd and 2nd millennium BC. Carpet-making was introduced to Spain in 10th century by the Moors. The Crusades brought Turkish carpets to all of Europe, where they were primarily hung on walls or used on tables. Only with the opening of trade routes in the 17th century were significant numbers of Persian rugs introduced to Western Europe.

Carpet types:
Woven
The carpet is produced on a loom similar to woven cloth and is a cut pile. Normally many coloured yarns are used and this process is capable of producing intricate patterns from pre-determined designs. These carpets are normally the most expensive.

Needlefelt
These carpets are more technologically advanced. Needlefelts are produced by electrostatic attraction of individual synthetic fibers forming an extremely durable carpet. These carpets are normally found in the contract market such as hotels etc. where there is a lot of traffic.

Others
A flatweave carpet is created by interlocking warp (vertical) and weft (horizontal) threads. Types of oriental flatwoven carpet include kilim, soumak, plain weave, and tapestry weave. Types of European flatwoven carpets include Venetian, Dutch, damask, list, haircloth, and ingrain (aka double cloth, two-ply, triple cloth, or three-ply).
A hooked rug is a simple type of rug handmade by pulling strips of cloth such as wool or cotton through the meshes of a sturdy fabric such as burlap. This type of rug is now generally made as a handicraft.
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 which was popular in the 1970s, to form the pile or nap of the carpet.

RUGS
An authentic oriental rug is a handmade carpet that is either knotted with pile or woven without pile. Oriental-design rugs made by machine or any method other than hand knotting or hand weaving are not considered authentic oriental rugs.
These rugs normally come from a broad geographical region extending from China and Vietnam in the east to Turkey and Iran in the west and the Caucasus in the north to India in the south. People from different cultures, countries, racial groups and religious faiths are involved in the production of oriental rugs.
Oriental rugs are organized by origin: Persian rugs, Anatolian rugs, Kurdish rugs, Caucasian rugs, Central Asian rugs, Turkestanian rugs, Chinese rugs, and Tibetan rugs.
