The related words "fabric" and "cloth" and "material" are often used in textile assembly trades (such as tailoring and dressmaking) as synonyms for "textile". However, there are subtle differences in these terms in specialized usage. A "textile" is any material made of the interlacing fibres, including carpeting and geotextiles, which may not necessarily be used in the production of further goods, such as clothing and upholstery. A "fabric" is a material made through weaving, knitting, spreading, felting, stitching, crocheting or bonding that may be used in the production of further products, such as clothing and upholstery, thus requiring a further step of the production. "Cloth" may also be used synonymously with "fabric", but often specifically refers to a piece of fabric that has been processed or cut.
