Abstract
In order to investigate the relationship between physical properties and tactile sensation/sensibility factors of felt, in this study we evaluated the physical properties (including structural fiber characteristics, heat transfer features, and mechanical parameters) of different felts, together with the corresponding tactile sensation/sensibility factors. A total of 11 felt specimens were prepared from a variety of natural animal fibers such as Angora goats hair, Mongolian young lambs wool, Australian Merino wool, and Australian Corriedale wool, and by selecting some commercial fashion felts containing polyester fibers. Following tactile subjective evaluation using magnitude line scales, Rough, Puff, and Hard were extracted as tactile sensation factors, whereas Elegant and Wild were identified as tactile sensibility factors. Angora goats hair and Merino wool felts were rated as the most negative for Rough and as the most positive for Puff and Elegant among all felts. They were also classified as the most negative felts for Hard, together with Corriedale wool felt. As to tactile sensibility factors, Wild was the most strongly perceived in touching Mongolian young lamb felt. The study revealed that all tactile sensation and sensibility factors of felts are affected by their physical properties. In particular, Rough, Puff, and Wild, which are strongly related to one another, were mainly influenced by structural fiber characteristics such as fiber diameter and heat transfer features, while Hard and Elegant were mostly affected by the mechanical properties.
