Twine
Twine is a strong Thread (yarn), thread, light String (cord), string or cord composed of two or more thinner strands twisted, and then twisted together (Plying, plied). The strands are plied in the opposite direction to that of their twist, which adds torsional strength to the cord and keeps it from unravelling. This process is sometimes called reverse wrap. The same technique used for making twine is also used to make Thread (yarn), thread, which is thinner, yarn, and rope, which is stronger and thicker, generally with three or more strands. Natural fibres used for making twine include wool, cotton, sisal, jute, hemp, henequen, paper, and coir. A variety of synthetic fibres are also used. Twine is a popular substance used in modern-day crafting. Prehistoric The invention of twine is at least as important as the development of Stone tool, stone tools for early humans. Indeed, Elizabeth Wayland Barber has called the development of twine, which can be made far stronger and long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sisal
Sisal (, ) (''Agave sisalana'') is a species of flowering plant native to southern Mexico, but widely cultivated and naturalized in many other countries. It yields a stiff fibre used in making rope and various other products. The term sisal may refer either to the plant's common name or the fibre, depending on the context. The sisal fibre is traditionally used for rope and twine, and has many other uses, including paper, cloth, footwear, hats, bags, carpets, geotextiles, and dartboards. It is also used as fibre reinforcements for composite fibreglass, rubber, and concrete products. Taxonomy The native origin of ''Agave sisalana'' is uncertain. Traditionally, it was deemed to be a native of the Yucatán Peninsula, but no records exist of botanical collections from there. They were originally shipped from the Spanish colonial port of Sisal in Yucatán (thus the name). The Yucatán plantations now cultivate henequen (''Agave fourcroydes''). H.S. Gentry hypothesized a Chiapas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
String (cord)
String is a long flexible structure made from fibers twisted together into a single strand, or from multiple such strands which are in turn twisted together. String is used to tie, bind, or hang other objects. It is also used as a material to make things, such as textiles, and in arts and crafts. String is a simple tool, and its use by humans is known to have been developed tens of thousands of years ago.Susan Toby Evans, David L. Webster, ''Archaeology of Ancient Mexico and Central America: An Encyclopedia'' (2013), p. 812. In Mesoamerica, for example, string was invented some 20,000 to 30,000 years ago, and was made by twisting plant fibers together. String may also be a component in other tools, and in devices as diverse as weapons, musical instruments, and toys. History String was used in prehistoric times to make fire, as part of a drilling tool called the bow drill, which makes fire by friction, as well as fishing lines, nets, clothing, shelter making materials, bow str ...

Jute
Jute is a long, soft, shiny bast fiber that can be spun into coarse, strong threads. It is produced from flowering plants in the genus ''Corchorus'', which is in the mallow family Malvaceae. The primary source of the fiber is ''Corchorus olitorius'', but such fiber is considered inferior to that derived from ''Corchorus capsularis''. "Jute" is the name of the plant or fiber used to make burlap, hessian, or gunny cloth. Jute is one of the most affordable natural fibers and second only to cotton in the amount produced and variety of uses. Jute fibers are composed primarily of plant materials cellulose and lignin. Jute fiber falls into the bast fiber category (fiber collected from bast, the phloem of the plant, sometimes called the "skin") along with kenaf, industrial hemp, flax ( linen), ramie, etc. The industrial term for jute fiber is ''raw jute''. The fibers are off-white to brown and 1–4 meters (3–13 feet) long. Jute is also called the "golden fiber" for its color an ...

Hemp
Hemp, or industrial hemp, is a botanical class of ''Cannabis sativa'' cultivars grown specifically for industrial or medicinal use. It can be used to make a wide range of products. Along with bamboo, hemp is among the fastest growing plants on Earth. It was also one of the first plants to be spun into usable fiber 50,000 years ago. It can be refined into a variety of commercial items, including paper, rope, textiles, clothing, biodegradable plastics, paint, insulation, biofuel, food, and animal feed. Although chemotype I cannabis and hemp (types II, III, IV, V) are both ''Cannabis sativa'' and contain the psychoactive component tetrahydrocannabinol (THC), they represent distinct cultivar groups, typically with unique phytochemical compositions and uses. Hemp typically has lower concentrations of total THC and may have higher concentrations of cannabidiol (CBD), which potentially mitigates the psychoactive effects of THC. The legality of hemp varies widely among countrie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Textiles
Textile is an umbrella term that includes various fiber-based materials, including fibers, yarns, filaments, threads, different fabric types, etc. At first, the word "textiles" only referred to woven fabrics. However, weaving is not the only manufacturing method, and many other methods were later developed to form textile structures based on their intended use. Knitting and non-woven are other popular types of fabric manufacturing. In the contemporary world, textiles satisfy the material needs for versatile applications, from simple daily clothing to bulletproof jackets, spacesuits, and doctor's gowns. Textiles are divided into two groups: Domestic purposes onsumer textilesand technical textiles. In consumer textiles, aesthetics and comfort are the most important factors, but in technical textiles, functional properties are the priority. Geotextiles, industrial textiles, medical textiles, and many other areas are examples of technical textiles, whereas clothing and ...

Rope
A rope is a group of yarns, plies, fibres, or strands that are twisted or braided together into a larger and stronger form. Ropes have tensile strength and so can be used for dragging and lifting. Rope is thicker and stronger than similarly constructed cord, string, and twine. Construction Rope may be constructed of any long, stringy, fibrous material, but generally is constructed of certain natural or synthetic fibres. Synthetic fibre ropes are significantly stronger than their natural fibre counterparts, they have a higher tensile strength, they are more resistant to rotting than ropes created from natural fibres, and they can be made to float on water. But synthetic ropes also possess certain disadvantages, including slipperiness, and some can be damaged more easily by UV light. Common natural fibres for rope are Manila hemp, hemp, linen, cotton, coir, jute, straw, and sisal. Synthetic fibres in use for rope-making include polypropylene, nylon, polyesters (e.g. ...

Spinning Wheel
A spinning wheel is a device for spinning thread or yarn from fibres. It was fundamental to the cotton textile industry prior to the Industrial Revolution. It laid the foundations for later machinery such as the spinning jenny and spinning frame, which displaced the spinning wheel during the Industrial Revolution. Function The basic spinning of yarn involves taking a clump of fibres and teasing a bit of them out, then twisting it into a basic string shape. The spinner continues pulling and twisting to make it longer and longer, and to control the thickness. Thousands of years ago, people began doing this onto a stick, called a spindle, which was a very lengthy process. The actual wheel part of a spinning wheel does not take the place of the spindle, instead it automates the twisting process, allowing one to "twist" the thread without having to constantly do so manually, and also the size of the wheel lets one more finely control the amount of twist. The thread still ends up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henequen
Henequen (''Agave fourcroydes'') is a species of flowering plant in the family Asparagaceae, native to southern Mexico and Guatemala. It is reportedly naturalized in Italy, the Canary Islands, Costa Rica, Cuba, Hispaniola, the Cayman Islands and the Lesser Antilles. Overview The leaves of ''Agave fourcroydes'' yield a fiber also called henequen, which is suitable for rope and twine but not of as high a quality as sisal. It is the major plantation fiber agave of eastern Mexico, being grown extensively in Yucatán, Veracruz, and Tamaulipas. It is also used to make ''licor del henequén'', a traditional Mexican alcoholic drink. The plant appears as a rosette of sword-shaped leaves 1.2 to 1.8 meters long, growing out of a thick stem that may reach 1.7 meters (5 ft). The leaves have regularly spaced teeth 3–6 mm long and a terminal spine 2–3 cm long. Like sisal, ''A.fourcroydes'' is a sterile hybrid; the ovaries never produce seeds. The plant does produce bulbi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolní Věstonice (archaeological Site)
Dolní Věstonice (often without diacritics as Dolni Vestonice) is an Upper Paleolithic archaeological site near the village of Dolní Věstonice in the South Moravian Region of the Czech Republic, at the base of Děvín, Mount Děvín, . It dates to approximately 26,000 BP, as supported by radiocarbon dating. The site is unique in that it has been a particularly abundant source of prehistoric artifacts (especially art) dating from the Gravettian period, which spanned roughly from 27,000 to 20,000 BC. In addition to the abundance of art, this site also includes carved representations of men, women, and animals, along with personal ornaments, human burials and enigmatic engravings. Introduction Soon after excavations of this site began in 1924, the significance of Dolní Věstonice became apparent. Thousands of ceramic artifacts, many of which depicted animals, were found associated with the site. The animals molded in the clay include lions, rhinoceroses, and mammoths. These fig ...

Coir
Coir (), also called coconut fibre, is a natural fibre extracted from the outer husk of coconut and used in products such as floor mats, doormats, brushes, and mattresses. Coir is the fibrous material found between the hard, internal shell and the outer coat of a coconut. Other uses of brown coir (made from ripe coconut) are in upholstery padding, sacking and horticulture. White coir, harvested from unripe coconuts, is used for making finer brushes, string, rope and fishing nets. It has the advantage of not sinking, so can be used in long lengths in deep water without the added weight dragging down boats and buoys. Coir must not be confused with coir pith, which is the powdery and spongy material resulting from the processing of the coir fibre. Coir fibre is locally named 'coprah' in some countries, adding to confusion. Pith is chemically similar to coir, but contains much shorter fibers. The name coco peat may refer either to coir or the pith or a mixture, as both have go ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hohle Fels
The ''Hohle Fels'' () (also ''Hohlefels'', ''Hohler Fels'', German for "hollow rock") is a cave in the Swabian Jura of Germany that has yielded a number of important archaeological finds dating from the Upper Paleolithic. Artifacts found in the cave represent some of the earliest examples of prehistoric art and musical instruments ever discovered. The cave is just outside the town of Schelklingen in the state of Baden-Württemberg, near Ulm. Because of the outstanding archeological finds and their cultural significance, in 2017 the site became part of the UNESCO World Heritage Site Caves and Ice Age Art in the Swabian Jura. Discoveries The first excavation took place in 1870, yielding remnants of cave bears, reindeer, mammoths and horses as well as tools belonging to the Aurignacian culture of the Upper Paleolithic. Further excavations during 1958 to 1960, 1977, and 2002 yielded a number of spectacular finds, including several specimens of prehistoric sculpture such as an ivor ...
