Diagram titled Spinning jenny showing an operator using a hand wheel to rotate a cord-driven roller, drawing and twisting fibers from multiple clamped rovings onto tilted spindles; numbered callouts trace the process from roving to thread. — textile An annotated diagram showing how an operator uses a hand wheel, rollers, and spindles on a spinning jenny to draw and twist unspun fiber into thread.

Richard Arkwright and Samuel Crompton were pivotal figures in the mechanization of the textile industry during the 18th century.

Sir Richard Arkwright

In 1769, Arkwright patented the water frame, the first fully automatic, continuously operating spinning machine. Powered by a waterwheel, it produced strong cotton yarn suitable for warp, which was superior to the weaker thread produced by the spinning jenny. Because of its size and power requirements, Arkwright pioneered the factory system, moving production from homes into large, water-powered mills.123

Samuel Crompton

In 1779, Crompton invented the spinning mule, a machine that combined the best features of Arkwright’s water frame and Hargreaves’s spinning jenny. His invention could simultaneously draw out and twist fibers, allowing for the production of both fine and coarse yarn. The mule enabled a single operator to manage over 1,000 spindles at once, significantly advancing the mass production of high-quality thread.41
