摘要:
A wet-laid fibrous product is provided that comprises recycled cellulosic fibers, cellulose ester staple fibers, and residual recycled ink, where the fibrous product has less ink content compared to the ink content for a 100% cellulose comparative fiber wet-laid product, when processed under similar conditions. The wet-laid fibrous product can be formed from a deinked recycled paper pulp slurry, the pulp slurry comprising recycled cellulosic fibers, cellulose ester staple fibers, and ink. A deinking process for the slurry is also provided.
