Access Online via Elsevier Bolero Ozon. Edward Gurr. Synthetic Dyes in Biology, Medicine and Chemistry is a guide in selecting dyes for special purposes in biology, medicine, chemistry, and other related fields. It aims to help professionals including histologists, cytologists, and other biology and medicine experts, such as chemists and general scientists. The dyes discussed in this book are categorized in 17 different classes according to the nature of their salt-forming sidechains, the colligators. This book also presents the uses of each dye.

Chemical and Synthetic DyesVIDEO ON THE TOPIC: Making a dye from scratch and coloring some socks! - Dyes & Pigments
In the British chemist William Perkin found the first method to make synthetic dye from coal tar. This started an industrial revolution within the chemical industry. During the next decades, synthetic dyes replaced the natural dyes made of tropical plants that had been used by the textile industry for centuries. Great Britain and France dominated the first years of the production of synthetic dyes, but soon German and Swiss chemical plants took over product development as well as production.
The Norwegian textile industry imported dyes from Great Britain and Germany. Textiles professionals continued this tradition as far as an ongoing textile industry existed in the country.
Though there was no production of textile machinery or chemicals like dye in Norway, professionals were needed to run and maintain the factories. One of the young engineers to be educated was Ove Collett He graduated from Die Technische Hochschule in Dresden in , specializing in electrochemistry and dyes.
His dye samples as well as his papers are preserved at the museum. Ove Collett did not start working in the textile industry, however, but continued his education at MIT Massachusetts Institute of Technology. In , he founded the nutrition and vitamin company Collett AS that still produce dietary supplements and baby formula.
When Norway began to build its mechanical industries in the middle of the 19th century, it also meant building new links within Europe. This was part of the broader spread of the Industrial Revolution throughout Europe. The textile industry was among the first to be built and with it came new machines, knowledge and people, mostly from Germany and Great Britain, into Norway.

Springer Shop Bolero Ozon. Microbial Degradation of Synthetic Dyes in Wastewaters. Today synthetic dyes are used extensively in the textile dyeing, paper printing, color photography, pharmaceuticals, food and drink, cosmetic and leather industries. As of now, over , different dyes are available, with an annual production of over , metric tons. These industries discharge an enormous amount of colored effluents into natural water bodies, with or without treatment.

Chemical technology: Dyes
A dye is a coloured substance that chemically bonds to the substrate to which it is being applied. This distinguishes dyes from pigments which do not chemically bind to the material they colour. The dye is generally applied in an aqueous solution , and may require a mordant to improve the fastness of the dye on the fiber. Both dyes and pigments are colored, because they absorb only some wavelengths of visible light.

Natural Science Vol. Color is the main attraction of any fabric. No matter how excellent its constitution, if unsuitably colored it is bound to be a failure as a commercial fabric. Manufacture and use of synthetic dyes for fabric dyeing has therefore become a massive industry today. In fact the art of applying color to fabric has been known to mankind since BC. WH Perkins in discovered the use of synthetic dyes. Synthetic dyes have provided a wide range of colorfast, bright hues. However their toxic nature has become a cause of grave concern to environmentalists. Use of synthetic dyes has an adverse effect on all forms of life.
The great appeal of textiles lies in their colors and the way that color is used to create patterned effects. Color is applied by the process of dyeing, which in its simplest form involves the immersion of a fabric in a solution of a dyestuff in water. Patterned effects are obtained by selectively applying dyes to fabric, for example by roller printing. The amount of dyestuff required is very small, but its production and application require considerable skill.
International Journal of Environmental Science and Technology. Textile industries are responsible for one of the major environmental pollution problems in the world, because they release undesirable dye effluents. Textile wastewater contains dyes mixed with various contaminants at a variety of ranges. Therefore, environmental legislation commonly obligates textile factories to treat these effluents before discharge into the receiving watercourses.
