In 1728, the first bleaching company was founded by Scottish using crofting technique. They soaked the fabrics in a lye solution and washed them in water. After this, the fabrics were spread out in a large field for around two weeks. This process was replicated six times in order for fabrics to be whitened enough. “This method was repetitive, arduous, and took over large area of lands which could have been used for other purposes such as farming (Duncan).” In early 18th century, Karl Wilhelm Scheele, Swedish Chemist, discovered a highly reactive and greenish yellow gaseous halogen element and named it Chlorine. Later on, in 1785, Claude Berthollet, French Scientist, found the advantage of Chlorine; it was the most effective whitening agent (Morrison). He also invented the new hypochlorite bleach. It was consisted of soda ash which had soaked up Chlorine gas and named after the town where it was contrived, “Eau de Javelle” (Wagnall). During the Industrial Revolution, people produced the bleaching powder using lime. “They treated lime with water, spread them all over a large room, and pumped the chlorine gas into the room to be soaked up by the lime (Morrison).” It was used until liquid chlorine and sodium hypochlorite solutions were invented around World War
