Patent number: 5811045Abstract: There is provided in accordance with the present invention a process for making a helically crimped conjugate fiber containing at least a first polymeric composition and a second polymeric composition. The first and second polymeric compositions respectively contain different thermoplastic polymers having different solidification periods. The degree of latent helical crimp is controlled by selective addition of a nucleating agent to at least one of the first and second polymeric compositions.
