Cai Lun

True paper was invented in China by a court official, Gai Lun, in the year 105. Cai Lun found that by treating cotton rags in a certain way, the material would break down into a mushy mass of fibers. When more water was added, the mixture could be pressed and dried into a thin, hard sheet that could be used for writing. This true paper became popular because it was much lighter than bamboo mats and less expensive than silk, both of which were used as writing materials at the time. Gai s method of making paper eventually made its way to Europe, where it became the material of choice for use with the printing press in the fifteenth century. Industrialization and mechanization since that time have led to the modern paper industry and to the thousands of types and forms of paper that are a basic commodity of modern society. 

C.E. Paper and papermaking (Cai Lun) Although papyrus paper already existed, Gai Lun creates paper from a mixture of fibrous materials softened into a wet pulp that is spread flat and dried. The material is strong and can be cheaply mass-produced.
