Felt in the context of Fluid

A yurt (from the Turkic languages) or ger (Mongolian) is a portable, round tent covered and insulated with skins or felt and traditionally used as a dwelling by several distinct nomadic groups in the steppes and mountains of Inner Asia. The structure consists of a flexible angled assembly or latticework of wood or bamboo for walls, a door frame, ribs (poles, rafters), and a wheel (crown, compression ring) possibly steam-bent as a roof. The roof structure is sometimes self-supporting, but large yurts may have interior posts or columns supporting the crown. The top of the wall of self-supporting yurts is prevented from spreading by means of a tension band which opposes the force of the roof ribs. Yurts take between 30 minutes and three hours to set up or take down, and are generally used by between five and 15 people. Nomadic farming with yurts as housing has been the primary way of life in Central Asia, particularly Mongolia, for thousands of years.

Modern yurts may be permanently built on a wooden or concrete platform; they may use modern materials such as metal framing, plastics, plexiglass dome, or radiant insulation.

The pileus (Ancient Greek: πῖλος, pîlos; also pilleus or pilleum in Latin) was a brimless felt cap worn in Ancient Greece, Etruria, Illyria (especially Pannonia), later also introduced in Ancient Rome. The pileus also appears on Apulian red-figure pottery.

The pilos together with the petasos were the most common types of hats in Archaic and Classical era (8th–4th century BC) Greece. In the 5th century BC, a bronze version began to appear in Ancient Greece and it became a popular infantry helmet. It occasionally had a horsehair crest. The Greek pilos resembled the Roman and Etruscan pileus, which were typically made of felt. The Greek πιλίδιον (pilidion) and Latin pilleolus were smaller versions, similar to a skullcap.

Nonwoven fabric or non-woven fabric is a fabric-like material made from staple fibre (short) and long fibres (continuous long), bonded together by chemical, mechanical, heat or solvent treatment. The term is used in the textile manufacturing industry to denote fabrics, such as felt, which are neither woven nor knitted. Some non-woven materials lack sufficient strength unless densified or reinforced by a backing. In recent years, non-wovens have become an alternative to polyurethane foam.

Natural fibers or natural fibres (see spelling differences) are fibers that are produced by geological processes, or from the bodies of plants or animals. They can be used as a component of composite materials, where the orientation of fibers impacts the properties. Natural fibers can also be matted into sheets to make paper or felt.

The earliest evidence of humans using fibers is the discovery of wool and dyed flax fibers found in a prehistoric cave in the Republic of Georgia that date back to 36,000 BP. Natural fibers can be used for high-tech applications, such as composite parts for automobiles and medical supplies. Compared to composites reinforced with glass fibers, composites with natural fibers have advantages such as lower density, better thermal insulation, and reduced skin irritation. Further, unlike glass fibers, natural fibers can be broken down by bacteria once they are no longer used.

A marker pen, fine liner, marking pen, felt-tip pen, felt pen, flow marker, sign pen (in South Korea), vivid (in New Zealand), flomaster (in East and South Slavic countries), texta (in Australia), sketch pen (in South Asia), koki (in South Africa) or simply marker is a pen which has its own ink source and a tip made of porous, pressed fibers such as felt.A marker pen consists of a container (glass, aluminum or plastic) and a core of an absorbent material that holds the ink. The upper part of the marker contains the nib that was made in earlier times of a hard felt material, and a cap to prevent the marker from drying out.

Until the early 1990s, the most common solvents that were used for the ink in permanent markers were toluene and xylene. These two substances are both harmful and characterized by a very strong smell. Today, the ink is usually made on the basis of alcohols (e.g. 1-Propanol, 1-butanol, diacetone alcohol and cresols).

A petasos (Ancient Greek: πέτασος) or petasus (Latin) is a broad brimmed hat of Thessalian origin worn by ancient Greeks, Thracians and Etruscans, often in combination with the chlamys cape. It was made of wool felt, leather, straw or animal skin. Women's versions had a high crown while those for men featured a lower crown. It was worn primarily by farmers, travellers and hunters, and was considered characteristic of rural people. As a winged hat, it became the symbol of Hermes, the Greek mythological messenger god.

Along with the pileus, the petasos was the most common hat worn in Ancient Greece. Its wide brim protected the wearer from the sun and rain while a lengthy strap allowed wearers to secure it under the chin. Its popularity later extended to the Etruscans, the Byzantine Empire and the Roman Empire, in slightly modified forms.

The kalpak, qalpaq or calpack, is a Turkic high-crowned cap (usually made of felt or sheepskin) worn by Turks, Turkmens, Karakalpaks, Bulgarians, Circassians, Dagestanis, Chechens, Ukrainians, Poles, Russians and throughout Central Asia and the Caucasus.

The kalpak is used to keep the head warm in winter and shade out the sun during summer. There are different kalpaks for different seasons, with kalpaks used in winter being thicker and the ones used in summer being thinner but broader for shading purposes.

A guitar pick is a plectrum used for guitars. Picks are generally made of one uniform material, such as some kind of plastic (nylon, Delrin, celluloid), rubber, felt, tortoiseshell, wood, metal, glass, tagua, or stone. They are often shaped in an acute isosceles triangle with the two equal corners rounded and the third corner less rounded. They are used to strum chords or to sound individual notes on a guitar.

A beret (UK: /ˈbɛreɪ/ BERR-ay, US: /bəˈreɪ/ bə-RAY; French: béret [beʁɛ]; Basque: txapel [t͡ʃa.pel]; Spanish: boina [ˈbojna]) is a soft, round, flat-crowned cap made of hand-knitted wool, crocheted cotton, wool felt, or acrylic fibre.

Mass production of berets began in the 19th century specifically in the Basque Country, where they were already common headwear among the indigenous population, before spreading to Southern France and the north of Spain; as such, the beret remains associated with these countries. Berets are worn as part of the uniform of many military and police units worldwide, as well as by other organizations.

A glove is a garment covering the hand, with separate sheaths or openings for each finger including the thumb. Gloves protect and comfort hands against cold or heat, damage by friction, abrasion or chemicals, and disease; or in turn to provide a guard for what a bare hand should not touch.

Gloves are made of materials including cloth, knitted or felted wool, leather, rubber, latex, neoprene, silk, and (in mail) metal. Gloves of kevlar protect the wearer from cuts. Gloves and gauntlets are integral components of pressure suits and spacesuits.

Bituminous waterproofing systems are designed to protect residential and commercial buildings. Bitumen (asphalt or coal-tar pitch) is a material made up of organic liquids that are highly sticky, viscous, and waterproof. Systems incorporating bituminous-based substrates are sometimes used to construct roofs, in the form of "roofing felt" or "roll roofing" products.

Angora hair or Angora fibre is the downy coat produced by the Angora rabbit. While the names of the source animals are similar, Angora fibre is distinct from mohair, which comes from the Angora goat. The cloth produced has sometimes been named Angola fabric. Angora fibre is also distinct from cashmere, which comes from the cashmere goat. Angora is known for its softness, thin fibres, and what knitters refer to as a halo (fluffiness). It is also known for its silky texture. It is much warmer and lighter than wool due to the hollow core of the angora fibre. It also gives the wool its characteristic floating feel.

Angora rabbits produce coats in a variety of colours, from white through tan, grey, and brown to black. Good quality Angora fibre is around 12–16 micrometres in diameter, and can cost as much as US$0.35–$0.56 per gram ($10–$16/oz). It felts very easily, even on the animal itself if it is not groomed frequently.

A felted material is a hairy or filamentous (hairy-like) fibre that is densely packed or tangled, forming felt or felt-like structures.

Wire wool is a generic term for products made of filaments entwined, woven or otherwise agglomerated into a sort of felt pad or belt that is often rolled for convenience. Typical dimensions for most domestic wire-wool might be about 1 cm/¼" thick by 8cm/3" broad and cut to various lengths.

Although "wire wool" and "steel wool" have become almost synonymous in general use, in engineering terms this is a misnomer as other metals, plastics and even natural fibers such as bristles may be incorporated singly or in combination within the wire-wool mesh according to purpose.

A coureur des bois (French: [kuʁœʁ de bwɑ]; lit. 'runner of the woods') or coureur de bois (French: [kuʁœʁ də bwɑ]; pl. coureurs de(s) bois) were independent entrepreneurial French Canadian traders who travelled in New France and the interior of North America, usually to trade with First Nations peoples by exchanging various European items for furs. Sometimes they operated in competition with the larger and licensed voyageurs. Some coureurs des bois learned the trades and practices of the indigenous peoples, and even went into business with them.

These expeditions were part of the beginning of the fur trade in the North American interior. Initially they traded for beaver coats and furs. However, as the market grew, coureurs de bois were trapping and trading prime beavers whose skins were to be felted in Europe.

Ancient furniture was made from many different materials, including reeds, wood, stone, metals, straws, and ivory. The furniture was decorated through processes like upholstery, inlaying, and through the use of finials.

It was common for ancient furniture to have religious or symbolic purposes. The Incans had chacmools which were dedicated to sacrifice. Similarly, in Dilmun they had sacrificial altars. In many civilizations, certain types of furniture were reserved for upper-class citizens. Stools and thrones made for nobility in Ancient Egypt were made of fine imported wood, occasionally animal bone, and were painted, gilded, and inlaid with metals. In Mesopotamia, tables were decorated with expensive metals, chairs would be padded with felt, rushes, and upholstery. Some chairs had metal inlays.
