A process is provided for applying sizing to a wet laid fibrous sheet that comprises providing an aqueous slurry that comprises cellulose fibers and cellulose ester staple fibers; forming the wet laid fibrous sheet from the slurry; and applying an aqueous sizing composition that comprises one or more sizing agents to the wet laid fibrous sheet. In embodiments, the cellulose ester staple fibers are present in an amount sufficient to permit the sheet to have a higher sizing composition uptake and to impart higher sizing properties to the sheet, compared to a sheet formed from a 100% cellulose fiber slurry, when processed under similar conditions.

A bale of sheets made of waste/recycle cellulose fibers and cellulose ester (CE) staple fibers can be fed to a hydropulper. The CE staple fibers have: i. a denier per filament (DPF) of less than 3, or ii. a cut length of less than 6 mm, or iii. crimping, or iv. a combination of any two or more of (i)-(iii).

The bales can be fed and dropped in as entire bales to a hydropulper, or a blend tank directly or indirectly in fluid communication with a hydropulper, using the same feed system employed for feeding cellulose to the hydopulper and avoiding having to defiberize by pulling or drawing fibers from a box container into a hydropulper. The waste/recycle cellulose fibers and CE staple fibers can be co-refined prior to making the bale of sheets.

A composition and process for making the composition by co-refining: fibrillated virgin cellulose fibers, waste/recycle cellulose fibers, or both; co-refined cellulose ester (CE) staple fibers having a denier per filament (DPF) of less than 3 and the weight percent of CE staple fibers is less than 30 wt. %, based on the weight of CE staple fibers and said cellulose fibers; and water. The composition can be co-refined to obtain lower Canadian standard freeness yet improved drainage and wet laid products having good tensile strength, air permeability, stiffness, burst strength, and bulk.
