James Hargreaves James Hargreaves James Hargreaves (c. 1720 – 22 April 1778) was a weaver, carpenter and inventor in Lancashire, England. He was one of three inventors responsible for mechanising spinning. Hargreaves is credited with inventing the spinning jenny in 1764, Richard Arkwright patented the water frame in 1769, and Samuel Crompton combined the two creating the spinning mule in 1779. James Hargreaves was born at Stanhill, Oswaldtwistle in Lancashire. He was described as "stout, broadest man of about five-foot ten, or rather more". He was illiterate and worked as a hand loom weaver during most of his life. He married and
Magnetic ring spinning Magnetic ring spinning Magnetic Ring Spinning, magnetic spinning, or innovative spinning is a ring spinning technology for making yarn based on magnetic levitation. This technique functions without a traveler sliding over the ring, enabling much higher spinning rates. Ring spinning stands alone as the standard of high quality yarn suitable for any type of textile end product. The main technological limitation of ring spinning lies with the metal/metal contact between the traveler and ring. This contact creates frictional heat and rapid wear, resulting in limitations on production speed, a drop in yarn quality with time. Magnetic ring spinning design approach
