  Abstract

In this study, inorganic TiO2 photocatalyst and organic guanidinylated chitosan were applied to HDPE fabric as antibacterial agents. Then we used an Ethanol solvent and Microwave curing because HDPE is a hydrophobic fabric and has few reactive sites. Both TiO2-treated and Gu-chitosan-treated samples prepared under optimal conditions showed excellent antibacterial activity of 99.9% against Staphylococcus aureus and Streptococcus pneumoniae. It maintained 99.9% antimicrobial properties after solvent washing. TiO2 photocatalyst has not only antimicrobial function but also self-cleaning function. In order to simultaneously materialize super hydrophobic and photo decomposition of HDPE fabric, hexadecyltrimethoxysilane 5 wt% and photocatalyst 3 wt% were applied. As a result, the contact angle was 152.9 ° showing excellent super hydrophobic properties. In conclusion, HDPE fabrics with excellent antimicrobial function and durability were produced by treating with TiO2 photocatalyst and Gu-Chitosan and then microwave curing. If further study to improve washing durability is conducted in the future, it is expected that the practicality of the fabricated fibers will be higher.
