Composition of matter in a pre-refiner blend zone

A composition is contained a blend zone prior to refining containing non-fibrillated virgin cellulose fibers, waste/recycle cellulose fibers or both; cellulose ester fibers, water, and one or more additives comprising fillers, internal sizing agents, biocides, process anti-foaming agents, colorants, optical modifiers, or a combination thereof. An in-line mixer can be used for adding the additives, and the consistency of the composition is lowered relative to a feed of material from a hydropulper.

Composition of matter in stock preparation zone of wet laid process

A composition obtained by combining virgin cellulose fibers, cellulose ester (CE) staple fibers having a denier per filament (DPF) of less than 3, and water, and water. The CE staple fibers can also have a short cut length of less than 6 mm and can be crimped. The compositions, when co-refined, are useful to make wet laid products such as paper, cardboard, and filters that have improved water drainage, air permeability, tensile strength, bulk, burst strength, or stiffness, or a combination of these properties.
