CRIMPED CONJUGATE FIBERS CONTAINING A NUCLEATING AGENT

摘要

There is provided in accordance with the present invention a helically crimped conjugate fiber containing at least a first composition and a second composition. The first and second compositions respectively contain different thermoplastic polymer having different solidification periods, and at least one of the two compositions contains a nucleating agent. Additionally provided is a process for controlling the level of crimps in the conjugate fiber.
