Commonly used in the textile industry, which unit of thermal resistance is used to measure the thickness of duvets?
Tog (unit) Tog (unit) The tog is a measure of thermal insulance of a unit area, also known as thermal resistance. It is commonly used in the textile industry and often seen quoted on, for example, duvets and carpet underlay. The Shirley Institute in Manchester, England developed the tog as an easy-to-follow alternative to the SI unit of mK/W. The name comes from the informal word "togs" for 'clothing', which itself was probably derived from the word "toga", a Roman garment. The basic unit of insulation coefficient is the "R", (1 mK/W). 1 tog = 0.1 "R". There is also a clo
Units of textile measurement pressure difference of 10 cm head of water", also known as the Gurley unit. Factors that affect air permeability include porosity, fabric thickness and construction, yarn density, twist, and crimp, layering, and moisture within the fabric. The concept of air permeability is important for the design of active wear and insect netting. The unit Martindale quantifies a textile's resistance to abrasion when used for upholstery. Units of textile measurement Textile fibers, threads, yarns and fabrics are measured in a multiplicity of units. Micronaire is a measure of the air permeability of cotton fiber and is an indication of fineness and
