Preparation of multifunctional cationized cotton fabric based on TiO2 nanomaterials

A novel approach for imparting multi-functional properties, i.e., UV-protecting, self-cleaning, water repellent as well as anti-bacterial properties onto cotton fabric is described. This research mainly deals with ecofriendly multifunctional cationized cotton fabrics using nanomaterialss based on TiO2 nanoparticles. In this study cotton fabric was cationized with two durable cationizing agent, 3-chloro-2-hydroxypropyl trimethyl ammonium chloride (Quat 188) and diallyl dimethyl ammonium chloride (DADMAC) using pad-batch method. The application of TiO2 nanomaterials on cotton 100% fabrics was achieved by using 1,2,3,4-butane tetracarboxilic acids [BTCA] as polycarboxilic cid cross linker with Sodium hypophosphite (SHP) as catalyst through conventional pad-dry-cure method. UV-protection, antibacterial and self-cleaning performances are investigated. Water repellent property of treated cationized cotton fabric post treated with stearic acid was also investigated.
