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 a manmade fibre such as polypropylene, and usually consists of twisted tufts which are often heat-treated to maintain their structure.
The carpet is produced on a loom similar to woven cloth and is usually a cut pile although looped pile carpets of woven construction are not unheard of. Normally many colored yarns are used and this process is capable of producing intricate patterns from pre-determined designs( although some limitations apply to certain weaving methods with regard to accuracy of pattern within the carpet). These carpets are normally the most expensive (although not always) due to the relatively slow speed of the manufacturing process.
