when was it invented?
The water frame was invented in England by Richard Arkwright and was patented in 1769.
At that time, James Hargreaves's spinning jenny was enjoying great success. However, the spinning jenny simply mechanized the actions of a hand-turned spinning wheel; it could not improve upon the actual quality of yarn produced.
