John Kay (spinning frame) a spinning machine embodying the ideas which they had been developing. Arkwright patented it 1769 without mentioning Kay, his "workman". Kay learned of this patent from another Nottingham inventor, James Hargreaves, and told Hargreaves that it was he, Kay, who was the real inventor. Arkwright accused Kay of revealing the design to Hargreaves, and the two fell out. Kay left Arkwright's Nottingham house, where he had been living, ending their relationship. Kay subsequently accused Arkwright of stealing his work tools, and Arkwright made a counter-charge . The spinning machine as constructed in Nottingham by Kay and Arkwright was powered by
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
