This paper will discuss the effects of replacing the traditional 100% wood pulp fibers used to produce absorbent cores with 100% cotton linters and three blends of cotton linter and wood pulp fibers. The study produced absorbent cores in two densities with two superabsorbent powder loadings per core density. The cores were tested for absorption, liquid acquisition, wet web integrity, multiple insult rewet, horizontal and vertical wicking. The energy used to defibrillate the cotton linter and wood pulp fiber sheets were also measured. The properties of wood pulp and cotton linter fibers will also be discussed.
