Abstract
Moisture flow through blended material is a complex
phenomenon. Clothing should possess good water
vapour as well as liquid moisture transmission
property, for providing the thermophysiological
clothing comfort. The clothing should take up the
moisture from the skin as well as transmit it to the
atmosphere. Higher hydrophilicity of a material is
known for good absorption, but how it really helps to
transmit the moisture, has been studied in the present
work. Polyester and viscose have been chosen as the
blending fibers and 8 fabrics with different blend
proportions were developed. Water vapour
transmission of the fabrics was measured using the
PERMETEST. Liquid water transmission property of
the fabrics was examined using a gravimetric inplane
wicking tester and a vertical wicking tester.
From the experimental result it has been observed
that water vapour permeability and absorbency of the
material increases with the increase in number of
hydrophilic group in the material, but it has an
adverse effect on the liquid moisture transmission
behavior of the material. The vertical as well as
horizontal wicking of the material decreases with the
increase in viscose proportion in the
polyester/viscose blended fabrics
