摘要： Tissue paper of the disclosure exhibits advantageous softness and bulk at a basis weight less than that of basis weights found in currently available commercial tissue products, while delivering adequate strength for machine runability and consumer usage. This tissue is a lightweight paper that comprises a fiber core with up to 60% mechanically fibrillated fibers and a retention or drainage aid such as a cationic polyacrylamide polymer that facilitates drainage, softness, and bulk. This approach can reduce the fiber content of tissue products significantly while delivering the desired strength and other critical properties.
