Effect of fibre diameter and cross-sectional shape on moisture transmission through fabrics

The current work incorporates an experimental study on the effect of fiber cross sectional shape and fibre diameter on moisture transmission properties of the fabric. Water vapour transmission of the fabrics was measured using the PERMETEST. In plane liquid flow through the fabric was measured using a gravimetric in-plane wicking tester and vertical movement of liquid along the fibres against gravity was also observed using a vertical wicking tester. With the change in shape factor and fibre diameter, it is seen that with increase in fibre specific surface area wicking rate through fabric increases, whereas water vapour permeability of the fabric reduces.
