The fibers are then processed into various cotton goods such as linens, while any undamaged cotton is used largely for textiles like clothing. The greatly expanded supply of cotton created strong demand for textile machinery and improved machine designs that replaced wooden parts with metal. This led to the invention of many machine tools in the early 19th century.]]> 2017-09-12 22:25:00 UTC https://padlet.com/samsonwongtsewan/qzthsr7l9a4m/wish/186988037 samsonwongtsewan https://padlet.com/samsonwongtsewan/qzthsr7l9a4m/wish/186988590

Crompton's first mule had 48 spindles and could produce 1 lb of 60s thread a day. This demanded a spindle speed of 1,700 rpm, and a power input of 1/16 hp.
The mule produced strong, thin yarn, suitable for any kind of textile. It was first used to spin cotton, then other fibres.
