A Study on the Recognition of Objective Fabric through a Fabric by a Fingertip

This study examined whether the fingertip could feel the features of the other fabric through a fabric. Samples were 13 types of fabrics with different properties. Combining samples in various ways, a sensory test was performed by a pair test method to see if the object fabric could be recognized through a fabric by three methods: touch, slide and touch-sack tests. As a result, the characteristics of the fabric including thickness, the compressional property, the surface property and the combined effect of the two fabrics affected the recognition of the object fabric. Among the test methods, the touch-sack test tended to be the most difficult to recognize the object fabric, while the touch test and the slide test were more likely to recognize the object fabric in this order. Using fabric data such as compressional properties and surface properties as explanatory variables, a discriminant analysis was performed in three groups: the group that can recognize the object fabric (G1), the group unable to recognize it (G2), and the group not belong to either (G3). By the analysis, the good discriminant equations were introduced. The analysis results also showed that the important parameters to recognize the object fabric were the thickness and its balance of the two fabrics, the compressional energy (WC) of the object fabric, SMD and the wavelength corresponding to the peak of the power spectrum obtained from the SMD signal wave. © 2021 Japan Research Association for Textile End-Uses.
