Abstract
This study examined the ultra-violet (UV) protection and anti-static characteristics with heat release by far-infrared (FIR) emissivity of Al2O3/Antimony Tin Oxide (ATO)/TiO2-imbedded PET fabrics according to the weight (wt.) percentage of the Al2O3/ATO particles imbedded in the yarns. The fabric with lower Al2O3/ATO wt. percentage had more effective heat release than that of the fabric with higher percentage due to the heat shielding property of the ATO particles. The fabric with lower Al2O3/ATO wt. percentage (higher TiO2) exhibited higher UV protection factor (UPF) than that of the fabric with higher percentage, which suggested that the UV protection characteristic of TiO2 particles imbedded in the yarn was superior to that of the Al2O3/ATO particles. The anti-static property of the higher wt.% of ATO-imbedded fabric was superior to that of the lower wt.% of ATO-imbedded fabric, which means that ATO inorganic particles provide superior anti-static property to the Al2O3 and TiO2 particles. On the other hand, Al2O3/ATO particles imbedded in the yarns imparted an uncomfortable tactile hand feel and wear fitness to the fabrics.
