An Investigation into comfort properties of polyester fabric by surface modification with polyvinyl alcohol

In this investigation the polyester multifilament fabric have been considered and treated with poly vinyl alcohol (PVA) in alkaline media. The fabric is treated with different concentration of PVA at different temperature and time. The effect of these factors concentration, temperature and time have been analyzed by Box-Behnken experimental design, and optimum parameters were found out. Further it is found that there is significant difference of these factors on to the comfort related properties that are air permeability and wicking. FTIR spectroscopy studies also have been carried to observe the surface modification by confirming the presence of hydrophilic group that is hydroxyl group.
