A technical textile is a textile product manufactured for non-aesthetic purposes, where function is the primary criterion. [1] Technical textiles include textiles for automotive applications, medical textiles (e.g., implants), geotextiles (reinforcement of embankments), agrotextiles (textiles for crop protection), and protective clothing (e.g., heat and radiation protection for fire fighter ...
Countries that primarily produce agricultural and other raw materials (i.e., primary sector) tend to grow slowly and remain either under-developed or developing economies. The value added through the transformation of raw materials into finished goods reliably generates greater profitability, which underlies the faster growth of developed ...
These thermal greases have low electrical conductivity and their volume resistivities are 1.5⋅10 15, 1.8⋅10 11, and 9.9⋅10 9 Ω⋅cm for 860, 8616 and 8617 respectively. The thermal grease 860 is a silicone oil with a Zinc Oxide filler and 8616 and 8617 are synthetic oils with various fillers including Aluminum Oxide and Boron Nitride.
Unblocked lace stole still on the needles. This item will expand significantly after pinning and blocking. Blocking can be done in several different ways. Depending on the method, the crafter may use rustproof pins, blocking wires, blocking combs, wool wash, a wash basing or sink, a spray bottle, a steamer, or a steam iron.
Thermal conductivity depends on the material and for fluids, its temperature and pressure. For comparison purposes, conductivity under standard conditions (20 °C at 1 atm) is commonly used. For some materials, thermal conductivity may also depend upon the direction of heat transfer.
A poncho (Spanish pronunciation:; Quechua: punchu; Mapudungun: pontro; "blanket", "woolen fabric") [1] [2] [3] is a kind of plainly formed, loose outer garment originating in the Americas, traditionally and still usually made of fabric, and designed to keep the body warm.
The insulation qualities of clothing materials are determined by the amount of "dead air" they can hold. The air is held in the voids inside the material itself as well as in the gaps between the clothing layers. Of the natural clothing materials, fur and leather provide the best insulation.
Material selection is a step in the process of designing any physical object. In the context of product design, the main goal of material selection is to minimize cost while meeting product performance goals. [1] Systematic selection of the best material for a given application begins with properties and costs of
