= Hemp hemp? (I wonder why is called differently? Is there a difference and what is it?)

Hemp Penkovo FIBER
WHAT IS HEMP?


Hemp (Sapnabis sativa)
- Annual herb with a stem length of 3 m or more in diameter 2,5-20 mm, applies to lubovoloknictym plants. Hemp fiber is located in the bast layer, called hemp (penkovolokno). Different countries have different names for hemp: hemp, hemp, marijuana, bhang, ganja, hashish, etc.

In Russia, two varieties of hemp grown - southern and central. South hemp growing in the Kuban, the Northern Caucasus, Central Russian - in Orel, Kursk, Bryansk, Penza region, in Mordovia. South hemp has a high (2 - 3 m) and thick (20 mm) stem. Its yield (up to 15 kg /ha) is significantly higher than the average Russian, but contains more fiber lignin - much coarser. Central Russian hemp is shorter than the South and, as a rule, thinner (2,5-7 mm). Central Russian hemp fiber is more coarse linen, but thinner hemp south.

Hemp - the plant is dioecious, ie there are male and female. Plants with male flowers are called "fimble", with women - "materkoy. They do not ripen simultaneously. Previously kept pace fimble later materka when fimble begins to dry and roughen. Once upon a time, in order to get a more subtle and soft fiber, fimble picked by hand, leaving ripen, until the seeds materku. Fiber fimble used to obtain hempen fabrics, and materki for ropes, cables and other twisted products.

To separate the fibers from the stalks of hemp her expose the biological retting, or spreading their. When lobe fiber retains lignin, and ropes made from it, better resist decay. In spreading their stalks of hemp hyphae of fungi destroy lignin, therefore, to develop a more fine yarns, especially wet-spinning, preferably using fiber stlantsevoe Central Russian hemp.

Hemp is one of the oldest and one of the most comprehensive economically useful plants. Archaeologists found the footprint of hemp fiber, which 10,000 years. Chinese medicine has opened therapeutic properties of cannabis more than 4000 years ago, they used the seeds for the treatment of pain, fever, ulcers, nausea, and many other ailments. Europe discovered hemp in stages, starting with the return from his trip to the East in 1297, Marco Polo, later, the Crusaders brought the seeds from the Middle East. Cannabis was introduced to South America in 1545 from Spain. Currently, hemp is grown in warm to temperate regions around the world.

Its fibers are used to manufacture high-quality paper, rope, ropes, canvas and cloth (the original Levi's jeans were made from hemp). Cannabis seeds are edible, and because its seeds are high in protein, making them a substitute for cheese. From ancient times to the hemp oil cooked food. He also poured into the lamps, illuminated the housing. Another hundred years ago the lights on the streets of Moscow ran the hemp oil. From hemp seed oil is also obtained for paints and varnishes, make laundry soap. Hemp seed cake - a valuable livestock feed.

By hygroscopic, anti-electrostatic and high physical-mechanical properties of hemp is similar to flax, hemp yields but higher and lower price. So now the world is increasing long-forgotten interest in the use of hempen fibers for the production of primarily heavy (such as canvas, denim, footwear), textiles, and mixed with linen and household (sheets, towels, tablecloths, etc.).

The peculiarity of cannabis, mostly to the south, is the presence in the inflorescences of drugs (hashish), and therefore tend to use bezgashishivye selected varieties. Central Russian hemp is usually not contain drugs. However, the fight against drug addiction has led to widespread reduction (up to complete destruction) of cannabis, and partly - reprofiling common in Soviet times penkozavodov in flax, in part - their complete closure.
Currently in Russia penkovolokno on an industrial scale is not performed.

Question on storing paintings, paintings.

I understand that in order to save space painting on canvas and stores and transmits to the stranding, Nakatani on the shaft-in roll form. If not confronted, will tell you where you can buy a tree and what its requirements, the technology of this case ... I saw them only on the photos in the museum.

Cardboard rolls of any length emit shops selling carpets (with mrozhno agree to leave), for a multi-fit tubes from the photo-wallpapers and out of the "dance" electronic mat ... (often thrown away), and from under posters ..
