Effectiveness of the “Tezawari” and “Hadazawari” sensory test methods in the evaluation of fine-textured knitted fabrics

“Tezawari” and “Hadazawari” are two sensory test methods used for fabric texture evaluation in Japan. In this study, the effectiveness of the two sensory test methods in coolness and moistness discrimination was investigated. Three types of single jersey fabrics that were distinct from each other in thermal and moisture properties were chosen as the samples. The coolness and moistness differences between the three types of samples were evaluated by 20 university students with both “Tezawari” and “Hadazawari” test methods. The comparative analysis of “Tezawari” and “Hadazawari” test results revealed that the coolness differences between samples were even more detectable when discriminated with the “Hadazawari” test method; the between-sample differences in perceived moistness correlated very well with the between-sample differences in perceived coolness in both “Tezawari” and “Hadazawari” tests. In conclusion, compared with the “Tezawari” test method, the “Hadazawari” test method is more suitable for coolness and moistness discrimination.
