Fiber Sources
See also: wood pulp and deinkingBefore the industrialisation of the paper production the most common fibre source was recycled fibres from used textiles, called rags. The rags was from hemp, linen and cotton. A process for removing printing inks from recycled paper was invented by German jurist Justus Claproth in 1774. Today this method is called deinking. It was not until the introduction of wood pulp in 1843 that paper production was not dependent on recycled materials.

Famous quotes containing the words fiber and/or sources:
“I taught school in the early days of my manhood and I think I know something about mothers. There is a thread of aspiration that runs strong in them. It is the fiber that has formed the most unselfish creatures who inhabit this earth. They want three things only; for their children to be fed, to be healthy, and to make the most of themselves.”
—Lyndon Baines Johnson (1908–1973)
“The sources of poetry are in the spirit seeking completeness.”
—Muriel Rukeyser (1913–1980)
