Offers adjustable airflow and selectable measuring areas for comprehensive air permeability analysis. Integrated with a user-friendly display for navigating various parameters.
The moisture vapor permeability measured using the upright cup (CaCl 2) method (JIS L 1099A-1) was primarily dependent on the hygroscopicity of the ecofriendly constituent fibers in the yarns and partly influenced by the pore size in the fabric because of the yarn structure. On the other hand, the moisture vapor resistance measured using the .A Water Vapour Permeability tester, also called a Moisture Permeability tester, or Water Vapour Transmission Tester, is used to measure the moisture permeability of all kinds of fabrics (including permeable coated fabrics) and clothing nonwovens such as cottonwool, space cotton, and sports cotton. The interaction of water and air i.e. moisture regain, water vapor transmission, wicking and air permeability with woven textiles are tested to investigate the comfort of woven fabrics made of nylon, cotton, and cotton–nylon mixtures with different yarn counts. The fabrics porosity (based on equation 1 and 2), woven fabric sett (ASTM D3775-03), fabric thickness .Fabric permeability testing. X. Ding, in Fabric Testing, 2008 7.4.1 Air permeability. Air permeability is defined as velocity of an air flow passing perpendicularly through a test specimen under specified conditions of test area, pressure drop and time (BS 3424-16-1995). The principle of the test is that the rate of flow of air passing perpendicularly through a given area of fabric .
