METHOD OF DEVELOPMENT OF MULTI-FUNCTIONAL PROPERTIES ON COTTON FABRIC BY SITU APPLICATION OF TIO2 AND NANO ZNO AND PRODUCT THEREOF

摘要

In this patent application, a method for preparation of multifunctional cotton fabric by coating it with Ti02 (Titanium Dioxide) and ZnO (Zinc Oxide) in a specific sequence is described. The cotton fabric prepared in this manner has self-cleaning, anti-bacterial and UV-blocking functional properties. The effect is most pronounced when the TIO2 coating is followed by ZnO coating rather than the other way round. It is found that Ti02 coating followed by ZnO coating on cotton fabric shows better results in terms of UPF (Ultra Violet protection Factor) rating, self-cleaning effectiveness and antimicrobial property in comparison to only TIO2 or ZnO coated fabrics. But most importantly, the fabric exhibits excellent durability to washing. This means that no extra treatment with any binding agent is needed which can reduce the permeability of the fabric. There was negligible difference in air permeability of treated fabric as compared to the untreated one. This means that comfort aspect of fabric is not compromised after treatment.
