发明名称 CELLULOSIC PRODUCTS CONTAINING CALCIUM CARBONATE FILLER
摘要 Cellulosic products comprising cellulosic fibers and precipitated calcium carbonate prepared in-situ during papermaking are described. The precipitated calcium carbonate is deposited on the cellulosic fibers and is present in a variety of sizes, shapes and morphologies, and is present in the cellulosic products on all physical features of the cellulosic fibers. At least a portion of the precipitated calcium carbonate is present with the fiber based on interaction with one or more chemicals used in papermaking.
