Cotton-spinning machinery The spinning jenny is a multi-spool spinning wheel. It was invented circa 1764, its invention attributed to James Hargreaves in Stanhill, near Blackburn, Lancashire. The Water frame was developed and patented by Arkwright in the 1770s. The roving was attenuated (stretched) by drafting rollers and twisted by winding it onto a spindle. It was heavy large scale machine that needed to be driven by power, which in the late 18th century meant by a water wheel. Cotton mills were designed for the purpose by Arkwright, Jedediah Strutt and others along the River Derwent in Derbyshire. Water frames could only spin
Dref Friction Spinning Dref Friction Spinning Friction Spinning or Dref Spinning is a textile technology that suitable for spinning coarse counts of yarns and technical core-wrapped yarns. Dref yarns are bulky, with low tensile strength making them suitable for blankets and mop yarns, they can be spun from asbestos, carbon fibres and make filters was water systems. Yarns such as Rayon and Kevlar can be spun using this method. The technology was developed around 1975 by Dr. Ernst Fehrer. There are three current technologies used today for spinning fibres: Friction spinning is the fastest of all these techniques though the yarn is irregular
