ECWCS
The Extended Cold Weather Clothing System (ECWCS ) is a protective clothing system developed in the 1980s by the United States Army Natick Soldier Research, Development and Engineering Center, Natick, Massachusetts. The first generation ECWCS consisted of Anorak, parka and trousers plus 20 other individual clothing, handwear, headwear and footwear items which are used in various combinations to meet the cold weather environmental requirements of the US military (and others). The Extended Climate Warfighter Clothing System, or Gen III ECWCS, is designed to maintain adequate environmental protection in temperatures ranging between . History In 1983, The U.S Department of Defense funded a three year development program. This was the start of ECWCS (Extended Cold-Weather Clothing System). In 1984, select units of the Marines, Navy Seals, and US Army were testing sample products in California, New York, and Italy. The next year, a thousand marines were deployed on exercise to Europe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polypropylene
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer Propene, propylene. Polypropylene belongs to the group of polyolefins and is Crystallization of polymers#Degree of crystallinity, partially crystalline and Chemical polarity#Nonpolar molecules, non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat-resistant. It is a white, mechanically rugged material and has a high chemical resistance. Polypropylene is the second-most widely produced Commodity plastics, commodity plastic (after polyethylene). History Phillips Petroleum chemists J. Paul Hogan and Robert Banks (chemist), Robert Banks first demonstrated the polymerization of propylene in 1951. The stereoselective polymerization to the isotactic was discovered by Giulio Natta and Karl Rehn in March 1954. This pioneering discovery led to large-scale commercial producti ...

Generation III Extended Cold Weather Clothing System
A generation is all of the people born and living at about the same time, regarded collectively. It also is "the average period, generally considered to be about 20–30 years, during which children are born and grow up, become adults, and begin to have children." In kinship, ''generation'' is a structural term, designating the parent–child relationship. In biology, ''generation'' also means biogenesis, reproduction, and procreation. ''Generation'' is also a synonym for ''birth/age cohort'' in demographics, marketing, and social science, where it means "people within a delineated population who experience the same significant events within a given period of time." The term ''generation'' in this sense, also known as ''social generations'', is widely used in popular culture and is a basis of sociological analysis. Serious analysis of generations began in the nineteenth century, emerging from an increasing awareness of the possibility of permanent social change and the idea ...

Taslan
Taslanizing or taslanising is a process for making air-textured yarns. Taslan is an expired registered trademark of DuPont for this process, first registered on October 19, 1954. In German the word is Luftex. The process is simply feeding a bundle of continuous filament yarns into a small jet nozzle with various amounts of slack (overfeed). High-pressure air ( > 100 PSI ) creates suction and a turbulent airstream which tangles any slack into a yarn with a similar hand as a spun yarn. It is the turbulent airflow that tangles the fibers. This method of yarn production creates a yarn that is normally more even than spun yarn and does not pill Pill or The Pill may refer to: Drugs * Pill (pharmacy), referring to anything small for a specific dose of medicine * "The Pill", a general nickname for the combined oral contraceptive pill Film and television * ''The Pill'' (film), a 2011 fil ... like spun yarn.

Drawcord
A drawstring (draw string, draw-string) is a string, rope or lace used to "draw" (gather, or shorten) fabric or other material. Ends of a drawstring are often terminated with a sheath called an aglet. The ends may be tied to hold the drawstring in place (and simultaneously close an opening). Alternatively, it may be kept drawn using a cordlock. Typically, the drawstring is loose when not being used and tightened when needed during use. A drawstring may be threaded through a hem or casing (a continuous tube of material) or laced through holes, which may be lined with eyelets. A shoelace is a drawstring. It may also be laced through loops attached to the material, in the same way that belt loops are. A belt is a usually flat drawstring. Hazard In 1996 the United States Consumer Product Safety Commission (CPSC) issued guidelines for drawstrings on children's upper outerwear to help prevent children from strangling or getting entangled on the neck and waist drawstrings of upper ...

Cargo Pocket
In transportation, cargo refers to goods transported by land, water or air, while freight refers to its conveyance. In economics, freight refers to goods transported at a freight rate for commercial gain. The term cargo is also used in case of goods in the cold-chain, because the perishable inventory is always in transit towards a final end-use, even when it is held in cold storage or other similar climate-controlled facilities, including warehouses. Multi-modal container units, designed as reusable carriers to facilitate unit load handling of the goods contained, are also referred to as cargo, especially by shipping lines and logistics operators. When empty containers are shipped each unit is documented as a cargo and when goods are stored within, the contents are termed containerized cargo. Similarly, aircraft ULD boxes are also documented as cargo, with an associated packing list of the items contained within. Description Marine Seaport terminals handle a wide range ...

Velcro
Velcro IP Holdings LLC, trading as Velcro Companies and commonly referred to as Velcro (pronounced ), is a British privately held company, founded by Swiss electrical engineer George de Mestral in the 1950s. It is the original manufacturer of hook-and-loop fasteners, which de Mestral invented. History Swiss electrical engineer George de Mestral who studied at EPFL invented his first touch fastener when, in 1941, he went for a walk in the Jura Mountains, Jura mountains, and wondered why burdock seeds clung to his woolen socks and coat, and also his dog Milka. He discovered it could be turned into something useful. He patented it in 1955, and subsequently refined and developed its practical manufacture until its commercial introduction in the late 1950s. The fastener consisted of two components: a lineal fabric strip with tiny hooks that could 'mate' with another fabric strip with smaller loops, attaching temporarily, until pulled apart. Initially made of cotton, which proved imp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hook And Loop
Hook-and-loop fasteners, commonly known as Velcro (a genericized trademark), hook-and-pile fasteners or touch fasteners are versatile fastening devices that allow two surfaces to be repeatedly attached and detached with ease. Invented in the mid-20th century, they are widely used in clothing, accessories, and various industrial and consumer applications. The fastener consists of two complementary components: one with tiny hooks and the other with soft loops. When pressed together, the hooks catch the loops, creating a secure but temporary bond. The fasteners can be separated by peeling or pulling the surfaces apart, often producing a distinctive ripping sound. History The original hook-and-loop fastener was conceived in 1941 by Swiss engineer George de Mestral, which he named velcro.The word Velcro is a portmanteau of two French words: "velours" meaning velvet, and "crochet" meaning hook. The idea came to him one day after he returned from a hunting trip with his dog in the A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Storm Flap
A storm is any disturbed state of the natural environment or the atmosphere of an astronomical body. It may be marked by significant disruptions to normal conditions such as strong wind, tornadoes, hail, thunder and lightning (a thunderstorm), heavy precipitation (snowstorm, rainstorm), heavy freezing rain (ice storm), strong winds (tropical cyclone, windstorm), wind transporting some substance through the atmosphere such as in a dust storm, among other forms of severe weather. Storms have the potential to harm lives and property via storm surge, heavy rain or snow causing flooding or road impassibility, lightning, wildfires, and vertical and horizontal wind shear. Systems with significant rainfall and duration help alleviate drought in places they move through. Heavy snowfall can allow special recreational activities to take place which would not be possible otherwise, such as skiing and snowmobiling. The English word comes from Proto-Germanic ''*sturmaz'' meaning "noise, tu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
