So that practical clothing may be described conveniently by a range of small integers, the unit of thermal resistance, to be called the “tog”, is the resistance that will maintain a temperature difference of 0.1°C. with a flux of 1 watt per square metre, or in more practical terms, 10°C. with a flux of 1 watt per square decimetre.
Nakidka weighs 2 kilograms per square metre (0.41 lb/sq ft) [1] and can be deployed in 0.4–1.0 man hours per square meter. It is also capable of withstanding combat conditions, such as taking small arms fire or a napalm attack. It is said to have a long maintenance-free service life. [2]
[4] [2] A stable flat surface, measuring tape, and towels are standard and some prefer to also use blocking mats or a blocking board. [4] Handmade socks are typically blocked on sock blockers. [4] Fibres that tolerate water well may be wet blocked, shaping moist fabric into the desired shape and then allowing it to air dry.
A chamanto (Mapudungun chamall, woolen fabric) [1] [2] is a traditional decorative garment from central Chile, similar to a poncho and woven in silk thread and wool. Its entire contour is finished with ribbon edging. Traditionally, Chilean festive ponchos incorporate colors such as grey, brown, red, black, and white.
Clothing insulation is the thermal insulation provided by clothing. [1] [2]Even if the main role of clothing is to protect from the cold, protective clothing also exists to protect from heat, such as for metallurgical workers or firemen.
This new pattern was printed on zeltbahn (triangular tent) material and could also be used as a camouflage rain poncho in the field. Both sides of the material showed the same pattern but the printing was brighter on one side. A subdued grey-beige tint replaced the yellow-ochre colour.
In 1983 the U.S. Army Research Laboratory in Natick, MA approached PrimaLoft's former parent company Albany International Corp., a global advanced textile and material processing company, [8] to develop a water resistant synthetic alternative to goose down for use in military sleeping bags and clothing systems in variable environmental conditions.
The process of manufacturing blackout was invented by Baltimore-based Rockland Industries, [2] and involves coating a fabric with layers of foam, or 'passes'. A '2-pass' blackout is produced by applying two passes of foam to a fabric – first, a black layer is applied to the fabric, then a white or light-colored layer is applied on top of the black.
