Appeal No. 97-4294 Page 24
Application No. 08/294,155
Example 7 included two sample materials (sample 7a and
sample 7b). The sample 7a material included 75% by weight of
a developmental acrylate superabsorbent 10 dtex by 12 mm fiber
labeled "FSA -111" produced by a joint venture of Courtaids®
Fibers Ltd. of Coventry, UK and Allied Colloids, Ltd. of
Bradford, UK, 20% by weight CR2054 fluffing pulp from
Kimberly-Clark Corporation of Neenah, Wis. and 5% by weight
bicomponent polyolefin binder fiber (Danaklon ES-C 3.3 dtex by
6 mm fibers from Danakalon a/s of Varde, Denmark). Sample 7b
used the same materials as sample 7a with the addition of the
cellulose acetate fine wettable fibers described and used in
sample 6b. Sample 7b comprised 75% by weight superabsorbent
fiber, 16% by weight fine wettable fiber, 4% fluffing pulp and
5% by weight binder fiber.
A comparison of the claimed subject matter (using claim 1
as a guide) to the above teachings of Jackson reveals that
Jackson does not specifically disclose that (1) the pulp
fibers are wettable, (2) the binder fibers are wettable and
(3) the liquid uptake rate is at least 2 times greater than
the article with no wettable staple fiber.
