Individualized, crosslinked fibers and process for making said fibers |
(57) Individualized, crosslinked fiber, and process for making such fibers. The individualized,
crosslinked fibers have between about 0.5 mole % and about 3.5 mole % crosslinking
agent, calculated on a cellulose anhydroglucose molar basis, reacted with fibers in
the form of intrafiber crosslink bonds, wherein the crosslinking agent is selected
from the group consisting of C₂ - C₈ dialdehydes, C₂ - C₈ dialdehyde acid analogues
having at least one aldehyde functionality, and oligomers of such C₂ - C₈ dialdehydes,
and dialdehyde acid analogues. Preferably, the crosslinking agent is glutaraldehyde,
and between about 0.75 mole % and about 2.5 mole % crosslinking agent react to form
the intrafiber crosslink bonds. The individualized crosslinked fibers are useful in
a variety of absorbent sturcture applications.
