Spinning Jenny and James Hargreaves:
-invented by James Hargreaves
-allowed thread to be made faster
-eight spindles, spun from corresponding set of roving’s, driven by hand crank, entirely hand operated mechanism
-made making thread 10 times faster than in the past
-thread machine produced was coarse and lacked strength, making suitable for only filling of weft, thread woven across the warp
– sets up small spinning mill in Nottingham
-in 1778, latest version of spinning jenny worked eighty spindles each
-first practical spinning frame with multiple spindles
-simple wooden framed machine, mainly used by home spinners
-worked in similar manner to the spinning wheel, first clamping down on the fibers then drawing them out, followed by twisting

Materials and Trade:
-20th century, all cloth made from plant/animal fibres
-woollen industry established in middle ages, production based on domestic industry
-cotton industry developed in three main districts: North West England, the Midlands, and the Clyde Valley in Scotland
-by 1802 cotton industry accounted for 4-5 percent of national income of Britain, production had now grown to 8 percent and had overtaken the woollen industry
-Britain’s climate and geography suited sheep, British woollen cloth was in high demand in Britain
-growing textile industry increased Britain’s desire to acquire new colonies and new sources of raw materials
-used two types of cotton, cotton with long fibres, and cotton with long fibres, mills favoured cotton with long fibres which was grown in Southern United States
-British demand, caused many people in Southern United States became cotton farmers, greatly increased slave trade
-colonies in India were used to supply cotton as well as dyes such as indigo
-sisal grown traditionally in places such as Mexico, Florida, and the Caribbean, in contrast to hemp, sisal is smoother and easier to work with. sisal twine commonly used by British farmers
Technology and work:
-New technology could speed up the steps of making products from raw materials and reduce work hours, inventions dramatically increased profits in the textile industry
-in the early 18th century Most textile production centred on small workshops or in the homes of spinners, weavers and dyers: a literal ‘cottage industry’ that involved thousands of individual manufacturers
-New techniques and technologies in agriculture paved the wave for change
-first employed the factory system
Technology:
Flying Shuttle: enabled weavers to weave faster (John Kay)
Spinning Jenny: First machine to improve spinning wheel (James Hargreaves)
Water Frame: first powered textile machine (Richard Arkwright)
Spinning Mule: greater control over weaving process (Crompton)
Cotton Gin: automated the separation of cottonseed (Eli Whitney)
Jacquard Loom: weaved complex designs, automatically controlled the warp and weft threads on a silk loom (Joseph Marie Jacquard)
Power Loom: increased weaving speed, allowed textile to be produced faster (Edmund Catwright)
