Appeal No. 1998-0240
Application 08/522,479
3. The conjugate fiber of claim 2 wherein said nucleating agent is selected from sorbitol
nucleating agents; metal salts of benzoic acid, dicarboxylic acid and arylalkanoic acid; sodium
2,2'-methylene bis(4,6-di-t-butylphenyl) phosphate; and mineral particles.
4. The conjugate fiber of claim 3 wherein at least one of said component compositions
comprises between about 0.005% and 2.0%, based on the total weight of said composition, of
said nucleating agent.
5. The conjugate fiber of claim 4 wherein both said first and second compositions contain said
nucleating agent.
9. A helically crimped multicomponent conjugate fiber comprising at least a first composition
and a second composition, said first composition comprising a first thermoplastic polymer and
said second composition a second thermoplastic polymer, said first thermoplastic polymer
having a shorter solidification period and higher melting point than said second thermoplastic
polymer, wherein said first composition contains an amount of nucleating agent effective to
increase the level of crimp within said fiber.
