摘要：
The disclosure is directed toward methods for delivering a pigment dispersion and an inverted retention aid emulsion to a papermaking process. The method comprises injecting the pigment dispersion and the inverted retention aid emulsion into a process line of the papermaking process. The pigment dispersion comprises titanium dioxide, and the retention aid may comprise an anionic flocculant. The process line is located downstream from a screen and upstream from a headbox. The methods may incorporate the use of one or several nozzle devices.
