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.
Claims19
A method of forming a macroalgae 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 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, wherein the dried macroalgae tissue web comprises from about 1 to about 4 percent macroalgae fibers.
A method of forming a macroalgae tissue web comprising the steps of:
- a. forming a macroalgae pulp by mixing never-dried macroalgae pulp fibers and once dried conventional papermaking pulp fibers;
- b. dispersing the macroalgae pulp to form a first fiber slurry;
- c. dispersing a conventional papermaking pulp to form a second fiber slurry;
- d. depositing the first and second fiber slurries onto a forming fabric to form a wet web;
- e. dewatering the wet web to a consistency of from about 20 to about 30 percent;
- and
- f. drying the wet web to a consistency of greater than about 90 percent thereby forming a dried macroalgae tissue web, wherein the dried macroalgae tissue web comprises from about 1 to about 4 percent macroalgae fibers.
A method of forming a multi-layered macroalgae 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. forming a multi-layered wet web by depositing the first fiber slurry on top of the second fiber slurry onto a forming fabric;
- d. dewatering the multi-layered wet web to a consistency of from about 20 to about 30 percent;
- and
- e. drying the multi-layered wet web to a consistency of greater than about 90 percent thereby forming a dried multi-layered macroalgae tissue web, wherein the first layer comprises conventional papermaking fibers and the second layer comprises from about 1 to about 4 percent, by weight of the total tissue web, 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.
