Much work has been going on in the development of increased retention of titanium dioxide. This thesis will investigate retention of titanium dioxide and drainage rates on the distribution of titanium dioxide.

The retention of titanium dioxide will be understood a little better if conditions having known effects on retention are stated. Literature states that retention of fillers increases with increased basis weight, (2) increased beating of the pulp, (1) with increased alum to a limit, (1) and decreases with interrelated machine conditions such as increased speed, vacuum in the suction boxes, and length of wire and shake.
