Abstract

The functionality such as deodorant, antibacterial, ultraviolet shielding of titanium dioxide self-actuated photocatalyst $Weltouch^{TM}$ treated polyester fiber was characterized in conditions without light. The deodorizing capacity was maintained more than 97% reduction irrespective of before washing and after 20 times repeated washing, and antimicrobial capacity was also retained more than 99.9% reduction. Titanium dioxide self-actuated photocatalyst was still maintained to the surface of polyester fiber without separation even after 20 times repeated washing. According to washing durability of polyester fiber, the reduction effect for ammonia was still retained even after 20 times repeated washing as much as before washing. The ultraviolet shielding capacity was still maintained at least 83% irrespective of before washing and 20 times repeated washing.

본 연구에서는 광촉매 작용을 하는 이산화티타늄 광촉매를 polyester 섬유에 코팅하여 탈취, 항균 및 자외선 차폐에 대한 기능을 부여하고 그 특성을 알아보았다. 그 결과 탈취성능은 세탁 전과 반복 20회 세탁 후에도 97%이상 저감되는 것으로 나타났으며, 항균성은 균수가 99.9%이상 감소되는 것으로 나타났다. 그리고 Polyester 섬유를 20회 반복 세탁을 행하여도 이산화티타늄 광촉매의 이탈 없이 표면에 견고하게 부착되어 있음을 확인하였으며, 또한 가스분해성능도 세탁전과 20회 반복 세탁 후에도 유지하는 것으로 나타나 세탁내구성이 우수함을 확인하였다. 자외선 차폐성도 세탁 전과 비교하여 20회 반복 세탁 후에도 83%이상 차단되는 것으로 나타났다.
