| Outline of Final Research Achievements |
In this study, we investigated the performance and the material properties of wadding materials for bedding and upholstery use. Following results are obtained. (1) Repeated compression and recovery behaviors under high humidity condition were investigated for the fiber assemblies made of twelve kinds of synthetic and regenerated fibers. (2) Compression and recovery property and compressive viscoelastic property were investigated for eight kinds of polyurethane foam for bedding and upholstery use. (3) Heat retaining properties of fiber assembly in low fiber volume fraction were investigated based on effective thermal conductivity. (4) Basic mechanical properties of fabrics for upholstery use were measured using KES-FB system in order to obtain fabric hand.
