Application No. 08/294,155
We find that there is a reasonable basis to conclude that
the pulp fibers used by Jackson (e.g., wood pulp fibers,
fluffing pulp) are wettable. Jackson is silent as to whether
or not his pulp fibers are wettable. However, since the
appellants' disclosure (specification, p. 9) informs us that
cellulosic fibers such as wood pulp fibers are wettable, it is
reasonable to conclude that the pulp fibers used by Jackson
(e.g., wood pulp fibers, fluffing pulp) are inherently
wettable.
Additionally, we find that there is a reasonable basis to
conclude that the binder fibers used by Jackson (e.g.,
polyolefins, nylons, polyesters, meltblown polypropylene,
bicomponent polyolefin (PE/PP)) are wettable. Jackson is
silent as to whether or not his binder fibers are wettable.
However, since the appellants' disclosure (specification, p.
11) informs us that thermoplastic compositions such as
polyethylene, polypropylene, polyesters such as polyethylene
terephthalate, polyamides such as nylon, are wettable, it is
reasonable to conclude that the binder fibers used by Jackson
(e.g., polyolefins, nylons, polyesters, meltblown
