| Abstract: | Wool fabric has
been treated with low-temperature plasma using a di-electric barrier discharge
plasma reactor under atmospheric pressure. Air was used as the non-polymerizing
gas for plasma treatment. The effect of plasma process parameters, viz voltage (4.0,
4.5, 5.0 and 5.5 kV) and the
inter-electrode spacing (2, 3 and 4 mm) on the properties of wool fabric has
been studied. Breaking strength, breaking elongation and low-stress mechanical
properties of the treated and untreated wool fabrics are evaluated. Surface
topographical changes after plasma treatment of wool have been assessed by
scanning electron microscopy. It is found that the tensile, bending,
compression, shear, and surface properties depend on the applied voltage
and the inter-electrode spacing. As the applied voltage across
the electrodes is increased and the inter-electrode spacing is decreased, the
etching effect of active species in plasma over
the wool substrate is increased. This results in improved
tensile properties at breaking load, increased bending and shear rigidity, and
decreased extension at low loads. |
