be either hydrophilic or hydrophobic, though hydrophilic
fibers are more desirable for liquid transport.
Jackson discloses the following specific examples of high
wicking liquid absorbent composites.
Example 1 included 62% by weight IM5000P superabsorbent
granules produced by Hoechst Celanese Corporation of Richmond,
Va., 16% by weight CR2054 fluffing pulp produced by
Kimberly-Clark Corporation of Neenab, Wis., 16% by weight
cellulose acetate Fibrets fibers produced by Hoechst Celanese®
Corporation of Charlotte, N.C. and 6% by weight generally
continuous macroscopic meltblown polypropylene reinforcing
fibers (i.e., binder fibers) having average diameters of
approximately 15 microns.
Example 2 included the same components as Example 1, the
difference being the relative weight percent of each
component. The material in Example 2 comprised 80% by weight
superabsorbent, 3% by weight fluffing pulp, 14% by weight
