Air Permeability Test for Fabric - Clothing Industry
Air Permeability Test for Fabric - Clothing Industry

Air permeability, affects the comfort aspect of a garment in terms of ,air, passage through the fabric. High ,air permeability, per unit area of a fabric gives lower ,protection, against winds, especially for outer-wear garments, whereas low ,air permeability, causes heavy body perspiration.

THL combines the performance of several fabric properties, including ,air permeability, and moisture wicking. ,Air permeability, is a key contributing factor to good THL performance. Certain garments have a low ,air permeability, rate, which limits evaporation and normal heat dissipation through airflow. This in turn increases body temperature and ...

20/6/2019, · The reciprocal of ,air permeability,, ,air, resistance, can be defined as the time in seconds for ImI of ,air, to pass through 100s mm2 of fabric under a pressure head of 10mm of water. The advantage of using ,air, resistance instead of ,air permeability, to characterize a fabric is that in an assembly of a number of fabrics, the total ,air, resistance is then the sum of the individual ,air, resistance.

5/2/2012, · Barry A. Perlmutter, in Solid-Liquid Filtration, 2015. ,Air Permeability,. ,Air permeability, is defined as the flow rate of ,air, per unit area at a given differential pressure and is normally expressed as cfm/ft 2 at 0.5 in. water gauge. Typical ratings can be from 2 to 2000. The result will be the relative pore size, so a small number would provide finer removal efficiency.

Havenith et al. (1995) investigated whether increasing the ,air permeability, of chemical ,protective clothing, helps to reduce heat strain (Fig. 6.9). Increasing the ventilation through the material from 186 to 365 l/m 2 increased the tolerance time from 174 ± 42 to 203 ± 56 min while walking on a treadmill.
