Abstract
The disclosure provides tissue webs, and products incorporating the same, where the webs comprise macroalgae fibers. More specifically the disclosure provides soft and durable tissue webs comprising at least about 1 percent macroalgae fiber by weight of the web. In the tissue webs of the present disclosure, macroalgae fibers may preferably replace high average fiber length wood fibers, which increases the strength and durability of the web without negatively stiffness.
Claims18
A tissue web comprising from about 1 to about 4 weight percent macroalgae fibers, the tissue web having a basis weight less than about 60 grams per square meter (gsm) and a sheet bulk greater than about 5 cm3/g.
A multi-layered tissue web comprising a first fibrous layer and a second fibrous layer, the first fibrous layer comprising conventional papermaking fibers and the second comprising macroalgae fibers, wherein the first fibrous layer is substantially free of macroalgae fibers and the second fibrous layer comprises from about 1 to about 4 percent macroalgae fiber by weight of the total web, the tissue web having a basis weight less than about 60 grams per square meter (gsm) and a sheet bulk greater than about 5 cm3/g.
