Hemp Paper
Hemp paper is paper varieties consisting exclusively or to a large extent from pulp obtained from fibers of industrial hemp. The products are mainly specialty papers such as cigarette paper, banknotes and technical filter papers. Compared to wood pulp, hemp pulp offers a four to five times longer fibre, a significantly lower lignin fraction as well as a higher tear resistance and tensile strength. Because the paper industry's processes have been optimized for wood as the feedstock, production costs currently are much higher than for paper from wood. History The first identified coarse paper, made from hemp, dates to the early Western Han Dynasty, 200 years before the nominal invention of papermaking by Cai Lun, who improved and standardized paper production using a range of inexpensive materials, including hemp ends, around 2000 years ago. Recycled hemp clothing, rags, and fishing nets were used as inputs for paper production. By the sixth century AD, the papermaking process ...

Paper
Paper is a thin sheet material produced by mechanically or chemically processing cellulose fibres derived from wood, rags, grasses or other vegetable sources in water, draining the water through fine mesh leaving the fibre evenly distributed on the surface, followed by pressing and drying. Although paper was originally made in single sheets by hand, almost all is now made on large machines—some making reels 10 metres wide, running at 2,000 metres per minute and up to 600,000 tonnes a year. It is a versatile material with many uses, including printing, painting, graphics, signage, design, packaging, decorating, writing, and cleaning. It may also be used as filter paper, wallpaper, book endpaper, conservation paper, laminated worktops, toilet tissue, or currency and security paper, or in a number of industrial and construction processes. The papermaking process developed in east Asia, probably China, at least as early as 105 CE, by the Han court eunuch Cai Lun, although the ...

Bank Note
A banknote—also called a bill (North American English), paper money, or simply a note—is a type of negotiable promissory note, made by a bank or other licensed authority, payable to the bearer on demand. Banknotes were originally issued by commercial banks, which were legally required to redeem the notes for legal tender (usually gold or silver coin) when presented to the chief cashier of the originating bank. These commercial banknotes only traded at face value in the market served by the issuing bank. Commercial banknotes have primarily been replaced by national banknotes issued by central banks or monetary authorities. National banknotes are often – but not always – legal tender, meaning that courts of law are required to recognize them as satisfactory payment of money debts. Historically, banks sought to ensure that they could always pay customers in coins when they presented banknotes for payment. This practice of "backing" notes with something of substance is ...

Cotton
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus ''Gossypium'' in the mallow family Malvaceae. The fiber is almost pure cellulose, and can contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, Egypt and India. The greatest diversity of wild cotton species is found in Mexico, followed by Australia and Africa. Cotton was independently domesticated in the Old and New Worlds. The fiber is most often spun into yarn or thread and used to make a soft, breathable, and durable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated to the fifth millennium BC have been found in the Indus Valley civilization, as well as fabric remnants dated back ...

Linen
Linen () is a textile made from the fibers of the flax plant. Linen is very strong, absorbent, and dries faster than cotton. Because of these properties, linen is comfortable to wear in hot weather and is valued for use in garments. It also has other distinctive characteristics, notably its tendency to wrinkle. Linen textiles appear to be some of the oldest in the world; their history goes back many thousands of years. Dyed flax fibers found in a cave in Southeastern Europe (present-day Georgia) suggest the use of woven linen fabrics from wild flax may date back over 30,000 years. Linen was used in ancient civilizations including Mesopotamia and ancient Egypt, and linen is mentioned in the Bible. In the 18th century and beyond, the linen industry was important in the economies of several countries in Europe as well as the American colonies. Textiles in a linen weave texture, even when made of cotton, hemp, or other non-flax fibers, are also loosely referred to as "linen". ...

India Paper
India paper is a type of paper which from 1875 has been based on bleached hemp and rag fibres, that produced a very thin, tough opaque white paper. It has a basis weight of 20 pounds (30 g/m2), yet bulks 1,000 pages to the inch. It became popular in particular for the printing of Bibles, which could be made relatively small and light while remaining legible. The 1911 Encyclopædia Britannica boasted, "Printed on thin, but strong opaque India paper, each volume but one inch in thickness." The process was used particularly by the Oxford University Press and its paper suppliers. The name arose because the paper imitated fine papers imported from the Indian subcontinent. India paper has also often been used for the printing of die proofs of postage stamps.

Hemp In France
Hemp (french: chanvre) has been grown continuously in France for hundreds of years or longer for use as a textile, paper, animal bedding, and for nautical applications. History There is archaeological evidence that Neolithic Europeans used hemp cloth in what is now Southern France 4,000 years BP. Hemp was introduced as a crop from Central and East Asia to Europe by the Scythians during the Bronze Age and it was cultivated in France by 1000 CE and used for a number of purposes including canvas for sails and sacks, rope, and as a textile. William Shakespeare wrote of the quality of hemp cloth from Locronan in the tragedy ''Coriolanus''. The Corderie Royale was built at Arsenal de Rochefort in 1666 for hemp rope needed by the Royal (French) Navy's rigging. In the 19th century, hemp production reached . Breton hemp (from Brittany) was considered some of the finest in the world. The French Navy "always" used national hemp sources for oakum necessary to seal wooden boats and ships ...

Rolling Paper
Rolling paper is a specialty paper used for making cigarettes (commercially manufactured filter cigarettes and individually made roll-your-own cigarettes). Rolling papers are packs of several cigarette-size sheets, often folded inside a cardboard wrapper. They are also known as 'blanks', which are used to encase tobacco or cannabis. It may be flavoured. Rolling papers are also used for rolling cannabis cigarettes called Joints. History The first cigarette paper was produced in Alcoy, Spain, in 1764. Paper cigarettes became popular in the second half of the 19th century, displacing the more expensive cigars and cigarillos. As cigars and cigarillos were expensive, the beggars of Spain would collect the cigar butts from the ground and roll them in pieces of paper to be smoked. During the Crimean War this culture became more prevalent and British soldiers learned how to roll tobacco in newspapers. Frequent use of rolling paper became a custom, and to fulfil the need, rolling paper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tetrahydrocannabinol
Tetrahydrocannabinol (THC) is the principal psychoactive constituent of cannabis and one of at least 113 total cannabinoids identified on the plant. Although the chemical formula for THC (C21H30O2) describes multiple isomers, the term ''THC'' usually refers to the Delta-9-THC isomer with chemical name (−)-''trans''-Δ9-tetrahydrocannabinol. THC is a lipid found in cannabis and, like most pharmacologically active secondary metabolites of plants, it is assumed to be involved in the plant's evolutionary adaptation, putatively against insect predation, ultraviolet light, and environmental stress. THC was first discovered and isolated by Israeli chemist Raphael Mechoulam in Israel in 1964. It was found that, when smoked, THC is absorbed into the bloodstream and travels to the brain, attaching itself to endocannabinoid receptors located in the cerebral cortex, cerebellum, and basal ganglia. These are the parts of the brain responsible for thinking, memory, pleasure, coordination a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
