Fire-retardant materials should not be confused with fire-resistant materials. A fire resistant material is one which is designed to resist burning and withstand heat. An example of a fire-resistant material is one which is used in bunker gear worn by firefighters to protect them from the flames of a burning building.
Cut-and-sewn gloves can be made using a cut-resistant material or by using conventional materials with full or palm lining of cut-resistant materials. The materials are cut to shape and sewn into a glove. Seamless knitted gloves are knitted in one piece by a flat knitting machine.
Puncture resistance denotes the relative ability of a material or object to inhibit the intrusion of a foreign object. This is defined by a test method , regulation, or technical specification . It can be measured in several ways ranging from a slow controlled puncture to a rapid impact of a sharp object or a rounded probe.
A cobble (sometimes a cobblestone) is a clast of rock defined on the Udden–Wentworth scale as having a particle size of 64–256 millimeters (2.5–10.1 in), larger than a pebble and smaller than a boulder. Other scales define a cobble's size differently. A rock made predominantly of cobbles is termed a conglomerate.
Typically, their undergarments beneath the heavier fire-resistant gear are made of flame-retardant cotton or another breathable, organic fabric that has been treated to resist ignition. [20] Polymers containing nitrogen, sodium, and phosphorus atoms can work as materials for fire-resistant cellulosic textiles, such as cotton or rayon ...
During welding, the glass shards and pumice fragments adhere together (necking at point contacts), deform, and compact together, resulting in a eutaxitic fabric. [18] Welded tuff is commonly rhyolitic in composition, but examples of all compositions are known. [19] [20] A sequence of ash flows may consist of multiple cooling units. These can be ...
These are directional fabrics such as Nikwax Analogy and FurTech, which are also breathable in the conventional sense (although these examples are actually a combination of two different fabrics, a directional "pump" layer underneath a distinct windproof and water-resistant outer layer; while effectively completely waterproof against rain, they ...
Fluorine-containing durable water repellent makes a fabric water-resistant. Durable water repellent, or DWR, is a coating added to fabrics at the factory to make them water-resistant (hydrophobic). Most factory-applied treatments are fluoropolymer based; these applications are quite thin and not always effective.
