There is provided in accordance with the present invention a helically crimped, pigmented conjugate fiber and a nonwoven fabric containing the conjugate fiber. The conjugate fiber contains at least a first composition and a second composition, and the first and second compositions contain different thermoplastic polymer having different solidification periods, wherein one of the two compositions contains a pigment or the two compositions contain disparate amounts of a pigment. Additionally provided is a process for simultaneously pigmenting a conjugate fiber and controlling the degree of latent crimpability in the conjugate fiber.
