Appeal No. 95-2622
Application 08/125,524
The melt-spinning processes of Bradley’s Examples II and
III are particularly relevant to appellant’s claimed invention
because they respectively describe production of five- and
ten-star Nylon-66 filaments and yarn melt-spun therefrom
(Bradley, col. 5, l. 25, to col. 6, l. 64). In Example II,
each slot of the five slot die used to produce five-lobe,
star-shaped filament was 25 mils long, i.e., minimum orifice
diameter of 25 mils and maximum orifice diameter of 50 mils
(Bradley, col. 5, l. 31-33). In Example III, each slot of the
ten slot die used to produce ten-lobe, star-shaped filament
was 50 mils long (including the 10 mil diameter of the orifice
core), i.e., a minimum orifice diameter of 50 mils and a
maximum orifice diameter of 100 mils (Bradley, col. 6, l. 14-
20). Bradley further teaches that the Example II “[s]amples
of yarn were drawtwisted at a draw ratio of 4.23 . . . and the
pentagonal filaments had more luster . . . and superior snag
resistance . . . ” (Bradley, col. 5, l. 74, to col. 6, l. 7).
The spun filaments of Example III “were subsequently
drawtwisted at 3.93 draw ratio” (Bradley, col. 6, l. 33-35)
and “these filaments imparted a highly attractive soft silky
sheen” (Bradley, col. 6, l. 63-64).
