Relationship between thickness feeling and physical thickness under different compressive load

Abstract

In this study, we investigated the relationship between thickness feeling for various fabric types and physical thickness under different compressive loads to clarify the effective range for human about fabric thickness. We selected eight fabric types and prepared 8 or 9 fabrics with different thickness in one fabric type. We measured thickness of samples using compression tester KES-FB3 under compressive load 0.5 gf/cm², 10 gf/cm², 20 gf/cm², 30 gf/cm², 40 gf/cm², 50 gf/cm², respectively. Sensory evaluation for the thickness of each fabric was carried out using SD method (semantic differential scale method) for 60 subjects. The nine fabric types were divided into two kinds which fabric types having a significant correlation between physical thickness and sensory evaluation score under any pressures, and fabric types having significant correlations in thickness under the compressive load of 0.5 and 50 gf/cm².
