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]
