  Abstract

This study examined the wear comfort properties of Al2O3/graphite-imbedded fabrics with sheath/core and dispersed PET yarns. The moisture absorption and drying characteristics were measured by a moisture management tester (MMT) method, and thermal property by a KES-F7 system. The results were discussed in terms of the ceramic-imbedded yarn structure, which was verified by the far-infrared emissivity and the maximum surface temperature measured by a light heat emission apparatus. In addition, the tactile hand feel of the fabric specimens was estimated from the fabric mechanical properties by a fabric assurance simple testing (FAST) system. The water absorption and drying properties of the Al2O3/ graphite sheath/core yarn fabric were inferior to those of the dispersed yarn fabric, and the heat retention rate was lower than that of the dispersed yarn fabric with lower thermal conductivity and higher Qmax value. These results revealed that the Al2O3/ graphite sheath/core yarn fabric has inferior wear comfort properties compared to those of the dispersed yarn fabric, which was attributed to the lower heat release from the core part of the sheath/core yarn than that from the dispersed yarn with Al2O3/graphite particles distributed over the whole yarn cross-section. This was further verified by the lower emissivity and maximum surface temperature of the sheath/core yarn fabric than those of the dispersed yarn fabric. However, the sheath/core yarn fabric exhibited slightly a softer tactile hand feel compared to the dispersed yarn fabric. Both sheath/core and dispersed yarn fabrics exhibited better wear comfort properties than the regular PET fabric did, but showed an uncomfortable tactile hand feel compared to the regular PET fabric.
