The Industrial Revolution brought huge changes to cloth manufacturing. The rise of European colonialism at the same time helped support the rapid growth of cloth production by creating many cheap sources of raw materials. British cloth manufacturers would import raw cotton from America and the British West Indies to Ireland, where it would be spun into yarn. The yarn would be imported into England, where mechanized factories employed thousands of workers, who would weave cloth on industrial looms. In 1781, a cloth producer from Manchester testified about his business to a committee of the House of Commons in the British Parliament. He stated that he employed 6000 workers, who would print and stamp 60,000 yards of cotton and linen fabric a year. Cotton gradually replaced linen for most uses in clothing, but remained preferred for bedsheets and tablecloths. Other European countries manufactured and traded their own types of household linens as well, and mass manufacturing techniques and trade competition gradually made affordable household linens common.
