The art of papermaking fibers of hemp was invented in China in the first century B.C. and it was kept as a state secret. Many historians attribute the breakthrough of this early Chinese culture, media technology. Until the fifteenth century, this technique did not come to Europe, where the Gutenberg revolution revolution first large-scale information) made it possible.
The “hemp paper” of other ancient cultures has been able to last about 1,500 years, approaching the resistance of ancient scrolls and codices. While in the case of ordinary paper, the length is 25 to 100 years. It also has great potential as support for file information printed or embossed (Brayle system, crinkled, etc.) in relation to the poor durability of the paper based on wood pulp.
The oldest surviving hemp paper is one made in China 2000 years, which has never stopped producing and processing hemp in its history ago.
The base wood pulp trees began to be used following the discovery of mechanical and chemical techniques were developed in England and Germany, unfortunately 95% of the current paper is made from tree cellulose.
Although the virgin hemp pulp is used to give more resistance to conventional paper when recycled, and that its long fibers allow twice recycled the wood pulp, unfortunately industries continue to value hemp as pulp basis only at a level experimental, and even analyzes by themselves conclude that hemp is uneconomical to manufacture conventional paper. Despite this special hemp pulp used for tea bags, banknotes, cigarette paper, technical filters for machines, paper for hygiene products and paper for artistic applications, it is precisely used for these applications by being the most high resistance to tear and break moisture.
The main argument to defend the massive use of hemp as raw material for cellulosic pulp has been the preservation of forests and biodiversity but has already claimed countless times that hemp produces three to four times more fiber useful per hectare and year the forests.
