Recycled wool, also known as rag wool or shoddy is any woollentextile or yarn made by shredding existing fabric and re-spinning the resulting fibres. Textile recycling is an important mechanism for reducing the need for raw wool in manufacturing.
Shoddy was invented by Benjamin Law of Batley in 1813.[1][2] It was the dominant industry of Batley and neighbouring towns in the West Riding of Yorkshire, known as the Heavy Woollen District, throughout the 19th and early 20th centuries.[3][4][5][6] Following its decline in the United Kingdom, the centre of the shoddy trade shifted to the city of Panipat in India.[7][8] Efforts have been made to revive the British recycled wool industry in the 21st century.[9]
Terminology
Historically, recycled wool products were called rag wool. Manufacturers distinguished among three main categories of rag wool:[3]
Shoddy – made from loosely woven or "soft" textiles that could be pulled apart relatively easily;
Mungo – made from "hard" fabrics such as felts, that were harder to disintegrate but resulted in a finer product;
Extract – made from the wool portion of cotton/wool blended fabrics.
In practice, few outside the industry were aware of these distinctions, even when rag wool was widely used.[3][10] The common name was shoddy, which became a generalised term for poor quality goods.[3] It is still used as a technical term for recycled wool within the industry.
Regulators in the United States make a distinction between reprocessed wool, which is made from manufactured wool products that were never used by the consumer, and reused wool, which the consumer has used.[11] Other bodies refer to these as pre-consumer and post-consumer waste material.[12]
The terms virgin wool and new wool are used to distinguish newly-produced, never-used wool from shoddy.[2]:13
