A person had to have a lot of capital to buy machines and open a factory. Those who were successful made huge profits with which to buy more machines, put up larger buildings, and purchase supplies in greater quantities at enormous savings. Thus capital increased far more rapidly than it ever had before. Much of it was invested in building canals, railroads, and steamships and in developing foreign trade. The men who controlled these enterprises formed a powerful new class in England--the industrial capitalists.
Samuel Crompton 's Spinning Mule was introduced in 1779. Mule implies "hybrid" because it was a combination of the spinning jenny and the water frame, in which the spindles were placed on a carriage, which went through an operational sequence during which the rollers stopped while the carriage moved away from the drawing roller to finish drawing out the fibres as the spindles started rotating.  :832 Crompton's mule was able to produce finer thread than hand spinning and at a lower cost. Mule spun thread was of suitable strength to be used as warp, and finally allowed Britain to produce highly competitive yarn in large quantities.  :832
