Print industry: An overview
Paper is essentially made up of natural fibres that have been separated and then rearranged into a sheet. The papermaking process - that is, the process of breaking up and reassembling individualfibres - was an abrupt departure from earlier methods for making writing materials such as parchment or papyrus. The parchment was made from hides by a special tanning process. Papyrus was made by pressing thin strips along natural fibre material cut from the papyrus tube in a product like modern papers.
Paper was first manufactured in China n 100A.D. but papermaking was not known in Europe until it was introduced by the Arabs in the mid-12th century. Paper was manufactured by hand, one sheet at a time, until about 1800. Except in the orient of,it was made of rags, mainly cotton and linen. When making paper sheet by sheet, the water problem was not a cause for concern. A large amount of water was not used at any point and its suitability for papermaking was judged by taste. For a long time before 1800, the Chinese made paper out of certain types of bark and other botanical ingredients, as well as rags. In 1719, after studying 4,444 wasp nests, the French naturalist Reaumur suggested that paper could be made from wood. The first practical method of making wood pulp was developed in 1840. This was the wood pulp process that provided pulp for most newsprint and a significant amount of other poor-quality papers. The wood pulp process is a purely mechanical process and does not remove woody substances from the wood pulp. The soda process to produce purified wood pulp was developed in 1851.Thus paper making and printing process advanced from ancient to modern times, and the use of print media has increased encompassing every aspect of human life.
This means printing industryis a very large industry which is used in education, newspaper, businesses and everywhere else. More use of printing process, more the need of water to make paper and print it.
Water treatment for Printing Industry
Water treatment companies place more emphasis on reusing water from all sources. Because today the biggest challenge for us is having abundant accessible water. And in some countries there is a lack of sufficient water sources.
Netsol, as a water treatment engineering company providing services for various industries such as Water treatment in the pharmaceutical industry, refinery water treatment, drinking water industry, food industry, etc.and can provide treatment plant for print industries. This can be used in screen printing, paper printing, dyeing process. The client performs screen printing on textiles and uses a lot of water in its process. Each place has a limited source of water and it is one of the highest raw material costs for entry. Before the ultrafiltration and reverse osmosis water treatment system, there is a special pre-treatment. Because we must treat wastewater before entering our water system. For this process, the customer reduces their water costs and increases the efficiency of their process.
