Subjective evaluation of hand knotted carpets

Abstract

Sixty-two different carpet samples have been evaluated for Carpet Aesthetic Value (CAV) and Carpet Hand Value (CHV) subjectively by ten different judges. Each carpet sample was considered individually and an estimated score was awarded on an arbitrary scale between 0 and 5. The rank correlations were worked out among different judges for CA V and CHV. The correlation coefficients for all the samples are found to be 0.37, 0.49 and 0.34 for CAV and 0.55, 0.53 and 0.52 for CHV for all the judges, manufacturers and users groups respectively, which are highly significant (p<0.01). This indicates that all the judges are in close agreement. The analysis to examine the influence of fibre mix, carpet constructional

parameters and finishing treatment reveals that the CHV is influenced by fibre mix and it increases with the increase in knot density and pile height upto some level, whereas antique and herbal wash treatments reduce the CHV value.
