Durable multifunctional properties on acrylic fabric using nano TiO2 and polysiloxane

Abstract

Producing fabric with multifunctional properties has been recently a center of research and utilizing nanoparticles is an efficient approach to gain this purpose. Here, nano TiO2 photo catalyst and polysiloxane softener were utilized as stabilizer on the acrylic fabric to obtain soft handle, hydrophilic, and self-cleaning features on the fabric. The effect of various concentrations of nano TiO2 and polysiloxane on the fabric handle, water droplet absorption time, and self-cleaning properties of the fabric has been mathematically modeled based on the response surface methodology (RSM). The optimized treatment conditions indicated that treated acrylic fabric with 2.19 % polysiloxane and 0.68 % nano TiO2 produced the rigidity of 26.8 g.cm, water absorption time of 15.8 s and self-cleaning of ΔE T *=18.1. Also increasing the concentration of polysiloxane enhanced both wettability and photoactive properties of nano TiO2 treated acrylic fabrics. Further, the nano TiO2/polysiloxane treated acrylic fabrics is significantly enable to absorb the light with wavelength lower than 400 nm and improve discoloration of C.I. Reactive Yellow 1.
