Parameters affecting warm-cool feeling in cotton denim fabrics

Received 9 June 2010; revised received and accepted 30 July 2010 Four greige cotton denim fabrics differing in weight per unit area have been subjected to five different finishing treatments. Physical and structural properties of these fabrics have been determined to assess their influence on warm-cool feeling to touch of the fabrics. It is observed that the lighter fabrics made of finer count yarns are cooler as compared to thicker fabrics. Higher pick density leads to an increase in q-max value and therefore the cool feeling. Washing treatments in general show a positive influence on cool feeling, while thickness, bulk density and cover factor show the reverse effect. q-max is found to be higher for fabrics with reduced geometric roughness or increased smoothness.
