Cotton
Cotton (), first recorded in ancient India, 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 civilizat ...

Sling (climbing Equipment)
A sling is an item of climbing equipment consisting of a tied or sewn loop of webbing. These can be wrapped around sections of rock, hitched to other pieces of equipment, or tied directly to a tensioned line using a Prusik style knot. They may be used as anchors, to extend an anchor to reduce rope drag, in anchor equalization, or to climb a rope. Uses In 1957 Jan and Herb Conn wrote an article titled "the versatile runner" with a long list of uses, which is still quite accurate: # Slings and now more often 3-foot alpine draws or shorter quickdraws are used in-between pieces of protection and the rope to minimize rope drag # Hitch around a chock stone or a tree to use as passive protectionConn, Jan and Herb (November 1957). ''The versatile runner'' - Summit (PDF) # Clove hitch around chicken heads or sling around horns # Longer slings or cordelettes can be used for equalized belay stations # Slings can be used as improvised "personal anchor system" attaching climber di ...

Rock Climbing Equipment
Rock-climbing equipment varies with the specific type of rock climbing, climbing that is undertaken. Bouldering needs the least equipment outside of climbing shoes, Chalk (climbing), climbing chalk and optional Bouldering mat, crash pads. Sport climbing adds climbing rope, ropes, climbing harness, harnesses, belay devices, and quickdraws to clip into pre-drilled Bolt (climbing), bolts. Traditional climbing adds the need to carry a "rack" of temporary passive and active #Protection devices, protection devices. Multi-pitch climbing, and the related big wall climbing, adds devices to assist in ascending and descending fixed ropes. Finally, aid climbing uses unique equipment to give mechanical assistance to the climber in their upward movement (e.g. aiders). Advances in equipment are a key part of the history of rock climbing, rock climbing history, starting with the climbing rope. Modern devices enable climbers to perform tasks previously done manually, with greater control – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SuperFabric
SuperFabric is a cut and abrasion resistant material, and a registered trademark of Higher Dimension Materials, Inc. As a technical fabric, SuperFabric is created with a base fabric such as nylon, polyester, neoprene, crepe, etc. and is overlaid with tiny, hard guard plates in a specific pattern. Spacings between the guard plates allow a degree of flexibility, breathability and are small enough to keep most sharp objects from penetrating. This guard plate technology protects the base fabric and contributes to the durability of the material. The geometry, thickness, and size of the guard plates, as well as the base fabric, vary depending on industry requirements. Customized and optional properties include flame resistance and specialized grip. Properties Cut resistance SuperFabric materials have tiny raised guard plates to deflect sharp objects that would otherwise tear the underlying base fabric. These guard plates are advertised to act as a protective barrier contributi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Strapping
Strapping, also known as bundling and banding, is the process of applying a strap to an item to combine, stabilize, hold, reinforce, or fasten it. A strap may also be referred to as ''strapping''. Strapping is most commonly used in the packaging industry. Types of strap Strap is a flat, flexible material, most commonly made from steel or various types of plastic. Steel Steel is the oldest and highest tensile strength strapping. It is available in a variety of widths and thicknesses as well as variations in the grade of steel. Steel is used for heavy duty holding where high strength and minimal stretch are desired. Surface finishes for steel strap include: paint, paint and wax, bluing, or zinc and wax. The wax is used to better transmit the tension around the bundle and for use with certain types of tensioners. Common applications include steel coils, bundles of metal, baling wire, bricks and other pavers, and roll end-binding. Steel strapping is sold by weight rath ...

Seat Belt
A seat belt, also known as a safety belt or spelled seatbelt, is a vehicle safety device designed to secure the driver or a passenger of a vehicle against harmful movement that may result during a collision or a sudden stop. A seat belt reduces the likelihood of death or serious injury in a traffic collision by reducing the force of secondary impacts with interior strike hazards, by keeping occupants positioned correctly for maximum effectiveness of the airbag (if equipped), and by preventing occupants being ejected from the vehicle in a crash or if the vehicle rolls over. When in motion, the driver and passengers are traveling at the same speed as the vehicle. If the vehicle suddenly halts or crashes, the occupants continue at the same speed the vehicle was going before it stopped. A seat belt applies an opposing force to the driver and passengers to prevent them from falling out or making contact with the interior of the car (especially preventing contact with, or going ...

Ultimate Tensile Strength
Ultimate tensile strength (also called UTS, tensile strength, TS, ultimate strength or F_\text in notation) is the maximum stress that a material can withstand while being stretched or pulled before breaking. In brittle materials, the ultimate tensile strength is close to the yield point, whereas in ductile materials, the ultimate tensile strength can be higher. The ultimate tensile strength is usually found by performing a tensile test and recording the engineering stress versus strain. The highest point of the stress–strain curve is the ultimate tensile strength and has units of stress. The equivalent point for the case of compression, instead of tension, is called the compressive strength. Tensile strengths are rarely of any consequence in the design of ductile members, but they are important with brittle members. They are tabulated for common materials such as alloys, composite materials, ceramics, plastics, and wood. Definition The ultimate tensile strength of ...

Kevlar
Kevlar (para-aramid) is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires. It is typically spun into ropes or fabric sheets that can be used as such, or as an ingredient in composite material components. Kevlar has many applications, ranging from bicycle tires and sailcloth#Kevlar, racing sails to bulletproof vests, due to its high Specific strength, tensile strength-to-weight ratio; by this measure it is five times stronger than steel. It is also used to make modern marching drumheads that withstand high impact, and for Mooring, mooring lines and other underwater applications. A similar fiber, Twaron, with the same chemical structure was developed by Akzo in the 1970s. Commercial production started in 1986, and Twaron is manufactured by Teijin Aramid. History Poly- ...

Dyneema
Ultra-high-molecular-weight polyethylene (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene (HMPE), it has extremely long chains, with a molecular mass typically between 2 and 6 million amu. The longer chain serves to transfer load more effectively to the polymer backbone by strengthening intermolecular interactions. This results in a very tough material, with the highest impact strength of any thermoplastic presently made. UHMWPE is odorless, tasteless, and nontoxic. It embodies all the characteristics of high-density polyethylene (HDPE) with the added traits of being resistant to concentrated acids and alkalis, as well as numerous organic solvents. It is highly resistant to corrosive chemicals except oxidizing acids; has extremely low moisture absorption and a very low coefficient of friction; is self-lubricating (see boundary lubrication); and is highly resistant to abrasion, in some forms being 15 times more resistant to a ...

Polyester
Polyester is a category of polymers that contain one or two ester linkages in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include some naturally occurring chemicals, such as those found in plants and insects. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. Synthetic polyesters are used extensively in clothing. Polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties. Cotton-polyester blends can be strong, wrinkle- and tear-resistant, and reduce shrinking. Synthetic fibers using polyester have high water, wind, and environmental resistance compared to plant-derived fibers. They are less Fireproofing, fire-resistant and can melt when ignited. Liquid crystalline polyesters are among the first industrially used liquid crystal polymers. They are used for their mechanical propert ...
