  • Publication number: 20200063356
    Abstract: 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.
