ATO 복합사를 이용한 열차단 직물의 태양방사투과율 변화 연구

In this study, we manufactured ATO (antimony tin oxide) combined fibers to improve solar energy transmittance of sunscreen fabrics. The results indicate that the solar energy transmittance is improved with increasing sheath ratios and ATO content. We observed that the MS2-7W sample with 50:50 sheath/core ratio and 3 wt% of ATO content show the best performance. We also manufactured the sunscreen fabrics using the devel-oped ATO combined fibers to check the performance of the thermal barrier. The results of the solar energy transmittance analysis show that an approximate 58% improvement was achieved for the thermal barrier over the commercial sunscreen fabric without any ATO content.
