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 increase the strength and durability of the web without negatively affecting stiffness.
Claims20
A layered tissue web comprising a first air contacting layer and a second fabric contacting layer, wherein the first air contacting layer comprises from about 0.5 to about 5 weight percent macroalgae fibers by weight of the web.
A layered tissue web comprising an air contacting layer comprising conventional papermaking fibers and from about 0.5 to about 5 weight percent macroalgae fibers by weight of the web, a middle layer comprising conventional papermaking fibers and a fabric contacting layer comprising conventional papermaking fibers, wherein the fabric contacting layer is substantially free of macroalgae fibers.
A method of forming a layered tissue web comprising the steps of:
- a. dispersing a macroalgae dry lap pulp to form a first fiber slurry;
- b. dispersing a conventional papermaking pulp to form a second fiber slurry;
- c. depositing the first and second fiber slurries onto a forming fabric such that the second fiber slurry contacts the forming fabric and the first fiber slurry contacts the air to form a wet web;
- d. dewatering the wet web to a consistency of from about 20 to about 30 percent;
- and
- e. drying the wet web to a consistency of greater than about 90 percent thereby forming a dried macroalgae tissue web.
