Title:
SELF-CLEANING COMPOSITION AND SELF-CLEANING FABRIC COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2022/146030
Kind Code:
A1
Abstract:
The present invention relates to a self-cleaning composition and a self-cleaning fabric comprising same, and can prevent adhesion of a contaminant by forming a coating layer on the surface of a textile and giving an ultra-hydrophobic property, and decompose the contaminant through a photocatalytic effect, caused by visible light sensitivity, for the contaminant substance adhered onto the surface of the textile. The present invention can also provide a textile capable of self-cleaning due to a photocatalytic effect caused by visible light sensitivity and due to an ultra-hydrophobic property by digitally printing an ultra-hydrophobic ink composition on a textile coated with a photocatalytic composition.
