S cience of Textiles

1. Perkins Purple It wasn't until 1856 that purple dye was synthesised, and could be cheaply produced. William Henry Perkins was trying to synthesise quinine, (a medicine for malaria) and accidentally produced the first chemical pigment. It happened to be purple. Science of Textiles Perkins left the Royal College of Chemistry to commercialise his invention, and developed the new industry of synthetic dyes (he went on to develop colours other than purple). He and other UK entrepeneurs initially dominated the market, but by the 1870s chemical dyestuffs were being produced and sold in greater numbers by German companies.

2. Discovery of mauveine then became know as - Mauve Mauveine was discovered serendipitously in 1856 by an 18-year old, William Henry Perkin, who was trying to synthesize the anti-malaria drug quinine as a challenge offered by his professor, August Wilhelm von Hofmann. In one of his attempts related to the quinine challenge, Perkin oxidized aniline using potassium dichromate. Under these conditions, the aniline reacted with toluidine impurities in it to produce a black solid, a fairly common result in "failed" organic syntheses. However, while trying to clean out his flask, Perkin discovered that some component of the black solid dissolved in alcohol to give a purple-colored solution, which proved to be an effective dye for silk and other textiles.

4. Edwardian fashions of the period were often in dull colours and blacks. Queen Victoria's long mourning put Britain into a gloomy darkness, and revolution, pollution and opression were reflected in the decades long trend for black. But the new artificial pigments were gaining ground, and by the 1920s fashion designers like Paul Poiret (influenced by the bright costumes of the Russian Ballet) were introducing vivid colour into ladies fashions. Mass production and the growth of ready made fashions, along with cheap synthetic dyes meant that purple clothing was finally becoming available to all. Sadly, during the 1930s dusty grey sackcloth and ashes dominated the fashion scene, followed by khaki uniforms in the early forties.
