Abstract
Abstract A polyester fiber textile material made by the application of titanium dioxide pigment thereto is provided. According to the process by which the textile material is made, the titanium dioxide pigment having a particle size of at least about 0.18 micron is exhausted from a dispersion of same onto the textile material at a pH below approximately 7.5. Subsequent heat setting of the polyester textile material improves retention of the titanium dioxide pigment.
