Discuss the scientific inventions that took place in the following fields. (a) Textile Industry (b) Metallurgy

Answer»

(a) Textile industry:

  • In the year 1738, John Kay made and patented the ‘flying shuttle’ which increased the speed of weaving.
  • The ‘spinning jenny’, a spinning frame with multiple spindles were made by James Hargreaves in England. It reduced the amount of labour and time of production.
  • In the year 1769, Richard Arkwright made a more advanced spinning frame. It could produce yarns much faster.
  • Samuel Crompton invented the ‘spinning mule’ in 1779 C. E.. This machine increased the speed of producing cloth two hundred times.
  • In 1785, Edmund Cartwright invented the power loom.
  • In 1793, a machine called the ‘cotton gin’ was introduced. This machine separated cotton seeds from cotton fibres at a greater speed.

(b) Metallurgy:

  • England had a number of iron mines.
  • Therefore, it was necessary to advance the technique of smelting iron to acquire purified iron from it.
  • The fuel for iron furnaces was replaced from wood to coal.
  • Special machines were made to keep the furnaces at a set temperature and to maintain their aeration.
  • In 1865, the process of producing steel from molten iron was invented and the nature of the iron industry underwent a major transformation.
  • At about the same time, a method was adopted to pour the molten metal into casts for making iron bars (e.g. rails).
