Water transfer properties of two‐layer weft knitted fabric

Abstract

The aim of this study is to investigate the water (moisture vapor and liquid) transfer properties of two‐layer weft knitted fabric and some related factors. Some experimental fabrics with specific yarns and stitch densities were prepared. Water vapor permeability rate through the fabrics and liquid water transfer from inner to outer layers were measured. The results show that the permeability rate is closely related to the porosity within the fabric while the transfer depends mainly upon the water absorption properties of the fibers on the two layers and degree of their difference.
