Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2020 / V.32,no.3,Sept Title Preparation and Evaluation of Self-cleaning Fabrics using Fe-doped TiO2 and Hexadecyltrimethoxysilane Authors Yejin Mun, Seungbin Cho, Euigyung Jeong and Jin-Seok Bae* Institution/Affiliations Kyungpook National University Pages/Total page pp.158 ~ 166 / 9 Language Korean Abstract Self-cleaning fabric is a fabric having a function of decotamination via photodecomposition of photocatalyst or wash-off of contaminants on the superhydrophobic surface. TiO2 is the main photocatalyst for this purpose, but it only functions under UV light which is only a little portion of sunlight, compared to visible light. In this regard, this study aims to investigate Fe-doped TiO2 for improved photodecomposition from visible light sensitization to apply self-cleaning finishing of PET fabrics. Moreover, the Fe-doped TiO2 treated PET fabric was further treated with hexadecyltrimethoxysilane to provide superhydrophobicity on the PET fabrics. As a result of this dual treatment, the prepared fabric exhibited excellent photodecomposition of methylene blue with 96.96% in 12h under sunlight and superhydrophobicity with water contact angle of 166.5° and roll-off angle of 7°. This suggested that the excellent self-cleaning functions can be privided to PET fabric via Fe-doped TiO2 and hexadecyltrimethoxysilane treatment.
