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. The flying shuttle (John Kay 1733) had increased yarn demand by the weavers
Spinning frame supplies became scarce especially due to innovations such as the doubling of the loom speed after the invention of the flying shuttle. High demand for yarn spurred invention of the spinning jenny in 1764, followed closely by the invention of the spinning frame, later developed into the water frame (patented in 1769). Mechanisms had increased production of yarn so dramatically that by 1830 the yarn cottage industry in England could no longer compete and all spinning was carried out in factories. Richard Arkwright employed John Kay to produce a new spinning machine that Kay had worked on with (or possibly
