Interference 103,685
invention are (Paper No. 1 (Notice Declaring Interference),
pp. 15-16):
Riggins’ Claim 1
A process of dyeing poly(m-phenyleneisophthalamide)
fabric comprising:
(a) dyeing the fabric at a temperature in the range of
about 100oC to about 150oC and elevated pressure in a fiber-
dyeing solution containing a tinctorial amount of at least
one dye and a dye diffusion promoting amount of an aromatic
amide having 7 to 14 carbon atoms capable of increasing the
swelling value of the fabric at least 1.5% then
(b) heating the fabric while in contact with the
solution until the desired degree of dyeing is attained.
Riggins’ Claim 13
A process of flame-retardant treating
poly(m-phenyleneisophthalamide) fabric comprising:
(a) treating the fabric with flame retardant at a
temperature in the range of about 100oC to about 150oC and
elevated pressure in a fiber-treating solution containing a
flame-retarding amount of at least one flame retardant and
a flame retardant diffusion promoting amount of an amide
having 7 to 14 carbon atoms capable of increasing the
swelling value of the fabric at least 1.5% then
(b) heating the fabric while in contact with the
solution until the desired degree of flame retardant
fixation is attained.
Riggins’ Claim 66
A fibrous material or fiber of an aromatic polyamide
that has been dyed with a dyebath comprising a mixture
of a dye diffusion promoting agent and a dye soluble or
dispersed with said agent, said agent comprising an
aromatic amide having 7 to 14 carbon atoms.
