Blackburn was a town with a population of about 5,000, known for the production of "Blackburn greys," cloths of linen warp and cotton weft initially imported from India. They were usually sent to London to be printed. At the time, cotton production could not keep up with demand of the textile industry, and Hargreaves spent some time considering how to improve the process.

Too large to be operated by hand, a spinning frame powered by a waterwheel became the water frame. In 1779, Samuel Crompton combined elements of the spinning jenny and water frame to create the spinning mule. This produced a stronger thread, and was suitable for mechanisation on a grand scale. A later development, from 1828/29, was Ring spinning. In the 20th century, new techniques including Open End spinning or rotor spinning were invented to produce yarns at rates
