摘要

2148448 9412725 PCTABS00032 Pulp is treated with an agent formed when water soluble metal salts are precipitated by adding a source of alkalinity to an acid salt solution to improve distribution of fines, whiteness of the pulp and/or binding of the fines to fiber for preparation of paper products. The treatment agent may be used alone or in combination with a surfactant which is precipitated onto the pulp fibers, and may be added to the pulp slurry during processing or formed in situ by adding the appropriate reagents to the pulp slurry.
