In the mid-18th century, artisans were inventing ways to become more productive. Silk, wool, and linen fabrics were being eclipsed by cotton which became the most important textile.
  Innovations in carding and spinning enabled by advances in cast iron technology resulted in the creation of larger spinning mules and water frames. The machinery was housed in water-powered mills on streams. The need for more power stimulated the production of steam-powered beam engines, and rotative mill engines transmitting the power to line shafts on each floor of the mill. Surplus power capacity encouraged the construction of more sophisticated power looms working in weaving sheds. The scale of production in the mill towns round Manchester created a need for a commercial structure; for a cotton exchange and warehousing. The technology was used in woollen and worsted mills in the West Yorkshire and elsewhere.
  Elements of the Industrial Revolution
  The commencement of the Industrial Revolution is closely linked to a small number of innovations, made in the second half of the 18th century:
