Some cotton paper contains a watermark. It is used for banknotes in a number of countries. These banknotes are typically made from 100% cotton paper, but can also be made with a mixture of 75% or less flax. [3] Other materials may also be used and still be known as currency paper. Higher quality art papers are often made from cotton.
The "handsheets" made according to TAPPI Standard T 205 [20] are circular sheets 15.9 cm (6.25 in) in diameter and are tested for paper characteristics such as brightness, strength and degree of sizing. [21] Paper made from other fibers, cotton being the most common, tends to be valued higher than wood-based paper. [citation needed]
Paper made from wood pulp is not necessarily less durable than a rag paper. The aging behaviour of a paper is determined by its manufacture, not the original source of the fibres. [ 27 ] Furthermore, tests sponsored by the Library of Congress prove that all paper is at risk of acid decay, because cellulose itself produces formic, acetic, lactic ...
It was not until the introduction of wood pulp in 1843 that paper production was not dependent on recycled materials from ragpickers. [114] It was not realized at the time how unstable wood pulp paper is. A means of removing printing inks from paper, allowing it to be re-used, was invented by German jurist Justus Claproth in 1774.

Pulp made from non-wood plant sources or recycled textiles is manufactured today largely as a speciality product for fine-printing and art purposes. [8] Modern machine- and hand-made art papers made with cotton, linen, hemp, abaca, kozo, and other fibers are often valued for their longer, stronger fibers and their lower lignin content.
Four other classes of material were sometimes used for writing: clay, wax, cloth, and metal. The value of metal for useful implements may have made it less than useful for practical writing and drawing. The hardness of many metals that made them useful also made it an inconvenient material for many kinds of writing.
Woodblock printing is a technique for printing text, images or patterns used widely throughout East Asia and probably originating in China in antiquity as a method of printing on textiles and later paper. As a method of printing on cloth, the earliest surviving examples from China date to before 220 CE/AD. [citation needed]
Ersatz cloth, woven paper, German, 1918-19 Auckland Museum, 1929.162.3-6 Man wearing a paper suit, 1920. In France in 1907, a thread made from paper was developed that was reported as being unshrinkable, damp-proof, fire-proof and two-thirds cheaper than cotton. [16] The New York Times article announcing this was headlined "Paper Dresses Soon ...
