41. An ozone fade resistant dyed carpet comprising:
a backing material; and
dyed sheath/core face fibers affixed to said
backing material and bound thereto, said face
fibers having (i) at least about 70 wt.% of a
core formed of at least one fiber-forming
core nylon selected from the group consisting
of nylon-6, nylon 6,6 and copolymers and
blends thereof, and (ii) a sheath completely
covering said core formed of a fiber-forming
nylon 6,12 homopolymer which exhibits
inherent chemical compatibility with the
core nylon and which is acid dye resistant,
wherein
said dyed sheath/core face fibers are dyed with an
difference from the original unexposed dyed sheath/core face
fibers after at least 3 cycles of ozone fading that is less than
one-half of the CIE L*a*b* total color difference seen for a
fiber composed substantially completely of said core nylon that
is dyed with the same acid dye.
