High strength macroalgae pulps

摘要

Novel pulps comprising conventional papermaking and macroalgae fibers are provided. By combining conventional papermaking fibers with never-dried macroalgae fibers, rather than dried macroalgae fibers, the disclosure provides pulp sheets having improved characteristics such as tensile and burst strength, with minimal deterioration in freeness.

主权项

1. A pulp sheet comprising from about 1 to about 30 weight percent never-dried macroalgae pulp fibers, the pulp sheet having a moisture content less than about 15 percent, a basis weight of at least about 150 grams per square meter and an MD Tensile Index greater than about 10 Nm/g.
