Textile Hand: Comparison of Two Evaluation Methods

Abstract

The article presents new test results concerning objective and subjective hand evaluation of 25 textile fabrics (woven and knitted). Textile hand was assessed subjectively by hand-picked judges panel, which in the way of direct survey assessed the fabrics in respect to 10 properties (smoothness, softness, thickness, roughness, weight, hardness, elasticity, stiffness, warmth and pleasing to handle) suitable to characterize the fabric hand. Textile hand was evaluated objectively using KTU-Griff-Tester on the basis of 5 determined parameters.
Comparative analysis was made between the results obtained by judges’ survey and the parameters determined experimentally by using the methods of mathematical statistics. The level of the judges’ agreement according to each fabric property was evaluated on the basis of Kendall’s concordance coefficient. Correlation between the assessment of the separate judge and the assessment of the total judges’ group was determined on the basis of Spearman’s rank correlation coefficient. Experimental data were estimated similarly as in the case of subjectively obtained results.
The obtained dependencies between the subjectively and objectively determined parameters, suitable for the textile hand characterization, are not linear therefore the correlation between the subjective and objective methods is tenuous and coincidental.
