Performance of cotton fabric finished by poly(butyl acrylate)/TiO_2 composite latex

Poly(butyl acrylate) /TiO2(PBA /TiO2) composite latex prepared by in-situ emulsion polymerization was used to finish cotton fabric via dip padding,and the functionality and wearability of the finished cotton fabric was compared with those of the other three cotton fabrics treated by mixed finishing dispersions(aqueous TiO2,PBA latex + TiO2,binder VECO + TiO2) on similar finishing process.The results indicated that under similar treating conditions,the TiO2 particles are small,well and evenly dispersed on the fiber surface of PBA /TiO2-treated cotton fabric,forming a thin film with little fiber to fiber adhesion inside the yarn.In essence,the single fiber coverage by PBA /TiO2 coating is realized,thus it has less influence on the wearability such as whiteness and handle.
