Process for the manufacture of multi-ply tissue

摘要

The invention relates to a process for the manufacture of a multi-ply tissue comprising at least two plies. The process comprises steps of mechanically refining a first slurry of fibers wherein the fibers have an average length of at least 2 mm; mixing the refined slurry with a second slurry of fibers, providing an embryonic web upon a foraminous surface, removing water from the embryonic web to form a ply; and juxtaposing at least two plies to form the multi-ply tissue.
