Appeal NO. 1996-3683
Application 08/207,393
On page 9, lines 15 through 18 of their specification,
appellants disclose that:
it has also been discovered that binders of the type
with free carboxyl groups produce especially strong
adhesion of the super absorbent particles and
fibers.
At page 13, lines 22 through 24, appellants disclose that
useful binders "include substances which can be applied in
liquid form to entrained fibers during the treatment process."
Appellants thereafter disclose that "suitable binders "
include polymeric materials in the form of emulsions or
solutions (page 13, line 36 through page 14, line 2 of the
specification). Exemplary suitable thermoplastic binders are
set forth on page 14, line 30 through page 15, line 13 of the
specification. Exemplary thermoset binders are set forth at
page 15, lines 16 through 24 of the specification.
Surfactants may also be included in the liquid binder (page
16, lines 11 and 12 of the specification). In Figure 1, a
mechanism is provided at the binder application zone 30 for
applying a liquid binder solution to the entrained fibers
(page 19, lines 25 through 27). Preferably, the binders are
"of a polymeric heat bondable type" (page 33, lines 20 and 21
of the specification).
In Example 1, cellulose fibers are sprayed with "PRIMACOR
