dyed," the appellants are on record (see Paper No. 4) as
stating that one of ordinary skill in the art would have
understood this term in accordance with the definition set
forth in Dictionary of Fiber & Textile Technology which 1
indicates that solution dyeing is "[a] term to describe a
manufactured fiber (yarn, staple, or tow) that has been
colored by the introduction of pigments or insoluble dyes into
the polymer melt or spinning solution prior to extrusion" and
that "[u]sually, the colors are fast to most destructive
agents."
Osborn discloses that "[a]ntimicrobial activity is
imparted to nylon during its preparation by adding to the
nylon forming monomer(s), a zinc compound . . . and a
phosphorus compound . . . [and that] [f]ibers made from the
resulting nylon contain the reaction product uniformly
dispersed therein and have antimicrobial activity of a
permanent nature" (Abstract). Of particular interest is
Osborn’s description of carpets made of such fibers which were
"blank dyed" (column 2, line 57) to produce test samples.
