Silnylon
Silnylon, a portmanteau A portmanteau word, or portmanteau (, ) is a blend of words Many colours are available. It is used in the manufacture of backpacks, tarps and tarp tents, bivouac shelter, bivy bags, etc., particularly by Ultralight backpacking, ultralight backpackers. Several types of silnylon are produced. The common type is a quiet, silky, very slippery fabric. The variant known as "crisp silnylon" is lighter, but brittle, noisy in mov ...

Ultralight Backpacking
Ultralight backpacking is a subset of lightweight backpacking, a style of backpacking which emphasizes carrying the lightest and least amount of gear. While no technical standards exist, some United States hikers consider "ultralight" to mean an initial base weight of less than 4.5kg (10 pounds). Base weight is the weight of a fully loaded backpack at the start of a trip, plus the gear inside and outside it, excluding consumables such as food, water, and fuel (which vary depending on the duration and style of trip). Base weight can be lowered by reducing the weight of individual items of gear, or by choosing not to carry that gear. Ultralight backpacking is most popular among thru-hikers—those hikers on extended trips (often of several months, or more) requiring resupply. In the United States the terms "light" and "ultralight" often refer to backpackers who carry gear with a base weight below and respectively. These weights are more easily achievable for smaller hikers. Large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silicone
A silicone or polysiloxane is a polymer made up of siloxane (−R2Si−O−SiR2−, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in sealants, adhesives, lubricants, medicine, cooking utensils, thermal insulation, and electrical insulation. Some common forms include silicone oil, silicone grease, silicone rubber, silicone resin, and silicone caulk. Chemistry More precisely called polymerized siloxanes or polysiloxanes, silicones consist of an inorganic silicon–oxygen backbone chain (⋯−Si−O−Si−O−Si−O−⋯) with two organic groups attached to each silicon center. Commonly, the organic groups are methyl. The materials can be cyclic or polymeric. By varying the −Si−O− chain lengths, side groups, and crosslinking, silicones can be synthesized with a wide variety of properties and compositions. They can vary in consistency from liquid to gel to rubber to hard plastic. The most common siloxan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tarp Tent
A tarp tent is a tarpaulin, a plastic or nylon sheet, used in place of a tent. It is usually rigged with poles, tent pegs, and guy lines. Ultralight backpackers use tarp tents because they are lightweight compared to other backpacking shelters. In its simplest form it is floorless with open ends, as a fly or with the sides attached to the ground. It can also be set up as a loue with two adjacent sides by the ground and the opposite corner as highest point, giving more protection from wind and reflecting heat from an optional fire in front of the open side. A tarp tent is commonly lighter and cheaper than a tent and easier to set up. However, because it is more open, it does not provide as much protection from rain, snow, wind, or cold as a tent does. It provides no protection from insects. More sophisticated tarp tents are now manufactured or homemade with such things as bug screening and storm flaps on the ends and even floors and vents. According to Harvey Manning in hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portmanteau
A portmanteau word, or portmanteau (, ) is a blend of wordsGarner's Modern American Usage , p. 644. in which parts of multiple words are combined into a new word, as in ''smog'', coined by blending ''smoke'' and ''fog'', or ''motel'', from ''motor'' and ''hotel''. In , a portmanteau is a single morph that is analyzed as representing two (or more) underlying s. When portmanteaus shorten es ...

Nylon
Nylon is a generic designation for a family of synthetic polymers composed of polyamides ( repeating units linked by amide links).The polyamides may be aliphatic or semi-aromatic. Nylon is a silk-like thermoplastic, generally made from petroleum, that can be melt-processed into fibers, films, or shapes. Nylon polymers can be mixed with a wide variety of additives to achieve many property variations. Nylon polymers have found significant commercial applications in fabric and fibers (apparel, flooring and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging). History DuPont and the invention of nylon Researchers at DuPont began developing cellulose based fibers, culminating in the synthetic fiber rayon. DuPont's experience with rayon was an important precursor to its development and marketing of nylon. DuPont's invention of nylon spanned an eleven-year period, ranging from the initial research pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bivouac Shelter
A bivouac shelter is any of a variety of improvised camp site, or shelter that is usually of a temporary nature, used especially by soldiers, or people engaged in backpacking, bikepacking, scouting, or mountain climbing. It may often refer to sleeping in the open with a bivouac sack, but it may also refer to a shelter constructed of natural materials like a structure of branches to form a frame, which is then covered with leaves, ferns, and similar material for waterproofing and duff (leaf litter) for insulation. Modern bivouacs often involve the use of one- or two-man tents but may also be without tents or full cover. In modern mountaineering the nature of the bivouac shelter will depend on the level of preparedness, in particular whether existing camping and outdoor gear may be incorporated into the shelter. A bivouac shelter is colloquially known as a bivvy (also spelled ''bivy'' or ''bivvi'' or ''bivi''). Etymology The word ''bivouac'' is French and ultimately derives from a ...

Hot Air Balloon
A hot air balloon is a lighter-than-air aircraft consisting of a bag, called an envelope, which contains heated air. Suspended beneath is a gondola or wicker basket (in some long-distance or high-altitude balloons, a capsule), which carries passengers and a source of heat, in most cases an open flame caused by burning liquid propane. The heated air inside the envelope makes it buoyant, since it has a lower density than the colder air outside the envelope. As with all aircraft, hot air balloons cannot fly beyond the atmosphere. The envelope does not have to be sealed at the bottom, since the air inside the envelope is at about the same pressure as the surrounding air. In modern sport balloons the envelope is generally made from nylon fabric, and the inlet of the balloon (closest to the burner flame) is made from a fire-resistant material such as Nomex. Modern balloons have been made in many shapes, such as rocket ships and the shapes of various commercial products, though the ...

Polyurethane
Polyurethane (; often abbreviated PUR and PU) refers to a class of polymers composed of organic chemistry, organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials. This chemical variety produces polyurethanes with different chemical structures leading to many List of polyurethane applications, different applications. These include rigid and flexible foams, varnishes and coatings, adhesives, Potting (electronics), electrical potting compounds, and fibers such as spandex and Polyurethane laminate, PUL. Foams are the largest application accounting for 67% of all polyurethane produced in 2016. A polyurethane is typically produced by reacting an isocyanate with a polyol. Since a polyurethane contains two types of monomers, which polymerize one after the other, they are classed as Copolymer#Alternating copolymers, alternating copolymers. Both the isocy ...

Woven Fabrics
Woven fabric is any textile formed by weaving. Woven fabrics are often created on a loom, and made of many threads woven on a warp and a weft. Technically, a woven fabric is any fabric made by interlacing two or more threads at right angles to one another. Woven fabrics can be made of both natural and synthetic fibres, and are often made from a mixture of both. E.g. 100% Cotton or 80% Cotton & 20% polyester. 60% spandex and 40% cotton could also be woven together. Woven fabric is typically used in clothing, garments, for decoration, furniture or covering purposes such as carpets. In the Midwest, it is popular to have woven wicker furniture in sitting areas such as a patio or a dining room. Qualities Woven fabrics only stretch diagonally on the bias directions (between the warp and weft directions), unless the threads used are elastic. Woven fabric cloth usually frays at the edges, unless techniques are used to counter it, such as the use of pinking shears or hem A hem in sewi ...
