Cai Lun, formerly romanized as Ts'ai Lun, was a Chinese eunuch court official of the Eastern Han dynasty. He occupies a pivotal place in the history of paper due to his addition of pulp via tree bark and hemp ends which resulted in the large-scale manufacture and worldwide spread of paper. Although traditionally regarded as the inventor of paper, earlier forms of paper have existed since the 3rd century BCE, so Cai's contributions are limited to innovation, rather than invention.
Papermaking is the manufacture of paper and cardboard, which are used widely for printing, writing, and packaging, among many other purposes. Today almost all paper is made using industrial machinery, while handmade paper survives as a specialized craft and a medium for artistic expression.
Pulp is a fibrous lignocellulosic material prepared by chemically, semi-chemically or mechanically producing cellulosic fibers from wood, fiber crops, waste paper, or rags. Mixed with water and other chemicals or plant-based additives, pulp is the major raw material used in papermaking and the industrial production of other paper products.
The pulp and paper industry comprises companies that use wood, specifically pulpwood, as raw material and produce pulp, paper, paperboard, and other cellulose-based products.
A paper mill is a factory devoted to making paper from vegetable fibres such as wood pulp, old rags, and other ingredients. Prior to the invention and adoption of the Fourdrinier machine and other types of paper machine that use an endless belt, all paper in a paper mill was made by hand, one sheet at a time, by specialized laborers.
Konjac and konnyaku are common names of Amorphophallus konjac, a vegetable species native to Yunnan in southwest China which has an edible corm. It is also known as konjaku, konnyaku potato, devil's tongue, voodoo lily, snake palm, or elephant yam.
Paper craft is a collection of crafts using paper or card as the primary artistic medium for the creation of two or three-dimensional objects. Paper and card stock lend themselves to a wide range of techniques and can be folded, curved, bent, cut, glued, molded, stitched, or layered. Papermaking by hand is also a paper craft.
Wove paper is a type of paper first created centuries ago in the Orient, and subsequently introduced to England, Europe and the American colonies in the mid-eighteenth century. Hand-made wove paper was first produced by using a wooden mould that contained a finely-woven brass vellum, upon which the paper pulp was applied and dried, creating a smooth, uniform surface.
Kage Kara Mamoru! is a Japanese series of light novels written by Achi Taro. The light novels had ended in March 2008 with the release of Volume 12, but as of July 2009, a new series entitled Motto! Kage Kara Mamoru! has started serialization. It features manga and anime adaptations. The main character is Mamoru Kagemori, a ninja who is sworn to protect his neighbor Yūna Konnyaku.
Sadao Watanabe, born and raised in Tokyo, was a Japanese printmaker. Watanabe was famous for his biblical prints rendered in the mingei tradition of Japan. As a student of the master textile dye artist Serizawa Keisuke (1895–1984), Watanabe was associated with the mingei movement.
Shirataki are translucent, gelatinous Japanese noodles made from the corm of the konjac plant. They are part of traditional Japanese cuisine, but they are also valuable to people with allergies or intolerances to wheat, gluten or eggs, or, for their low caloric value, to people restricting their energy intake by dieting.
Korean paper or hanji (Korean: 한지) refers to traditional handmade paper from Korea. Hanji is made from the inner bark of the paper mulberry, a tree native to Korea that grows well on its rocky mountainsides. Another crucial material used in its creation is the mucilage that oozes from the roots of Hibiscus manihot. This substance helps suspend the individual fibers in water.
Laid paper is a type of paper having a ribbed texture imparted by the manufacturing process. In the pre-mechanical period of European papermaking, laid paper was the predominant kind of paper produced. Its use, however, diminished in the 19th century, when it was largely supplanted by wove paper. Laid paper is still commonly used by artists as a support for charcoal drawings.
Damjing, or Donchō, was a Korean Buddhist priest who was sent to ancient Japan from Goguryeo around 610. How his name was pronounced in the Goguryeo language is unknown.
William Joseph "Dard" Hunter was an American authority on printing, paper, and papermaking, especially by hand, using sixteenth century tools and techniques. He is known for, among other things, the production of two hundred copies of his book Old Papermaking, for which he prepared all aspects: Hunter wrote the text, designed and cast the type, did the typesetting, handmade the paper, and printed and bound the book. A display at the Smithsonian Institution that appeared with his work read, "In the entire history of printing, these are the first books to have been made in their entirety by the labors of one man." He also wrote Papermarking by Hand in America (1950), a similar but even larger undertaking.
The Robert C. Williams American Museum of Papermaking is a research institution and public museum dedicated to the preservation of the history of paper and paper technology. Located inside the Paper Tricentennial Building at the Georgia Institute of Technology in Atlanta, Georgia, United States, the museum features the largest collection of paper and paper-related artifacts in the world, including watermarks, papers, tools, machines, and manuscripts. Changing exhibits focus on paper art, and a permanent exhibit details the science and technology used in papermaking.
Printing and writing papers are paper grades used for newspapers, magazines, catalogs, books, notebooks, commercial printing, business forms, stationeries, copying and digital printing. About 1/3 of the total pulp and paper marked is printing and writing papers. The pulp or fibers used in printing and writing papers are extracted from wood using a chemical or mechanical process.
Paper is a thin nonwoven material traditionally made from a combination of milled plant and textile fibres. The first paper-like plant-based writing sheet was papyrus in Egypt, but the first true papermaking process was documented in China during the Eastern Han period, traditionally attributed to the court official Cai Lun. This plant-puree conglomerate produced by pulp mills and paper mills was used for writing, drawing, and money. During the 8th century, Chinese paper making spread to the Islamic world, replacing papyrus. By the 11th century, papermaking was brought to Europe, where it replaced animal-skin-based parchment and wood panels. By the 13th century, papermaking was refined with paper mills using waterwheels in Spain. Later improvements to the papermaking process came in 19th century Europe with the invention of wood-based papers.
The wet strength of paper and paperboard is a measure of how well the web of fibers holding the paper together can resist a force of rupture when the paper is wet. Wet strength is routinely expressed as the ratio of wet to dry tensile force at break.
