Influence of Shrinkage on Air and Water Vapour Permeability of Double-Layered Weft Knitted Fabrics

Water vapour permeability and transport depends on the properties of the fibre and knitted fabric structure. It was designed double-layered fabrics knitted in plain plating pattern whose inner side was  made from synthetic fibres the PES, PA, PP, and Coolmax<sup>®</sup> (tetra-channel fi...
