ABSTRACTIn order to apply finishing particles onto fabrics, several methods such as, padding, bath exhaustion, spraying and foaming can be used. In this research, spray treatment is compared to padding when applying TiO 2 nanoparticles onto textile. Cotton fabrics´ surfaces were observed by scanning electron microscopy (SEM) and characterized by Fourier Transformed Infra Red (FT-IR) spectroscopy and energy dispersive using X-Ray (EDX). EDX technique showed that it was a suitable method to detect the presence of Ti particles on the fabric surface. We confirm that the fabric treated by padding procedure contained a higher quantity of Ti particles than the one treated by spraying. On the other hand, we compared two different auxiliary products to bind the particles onto the fibers, an acrylic resin and the polycarboxilic acid 1,2,3,4-butanetetracarboxylic acid (BTCA) in the presence of sodium hypophosphite (SHP). We used EDX to evaluate the effectiveness of both binders after washing . We improved the presence of TiO 2 particles on the fibers when using an acrylic resin, and observed that when BTCA, is used to fix the particles, there was no increase in the quantity of titanium on the fabric after 5 washing cycles compared to the sample without binder treatement.
