A polyamide fiber that includes 0.3 to 2.0 weight percent kaolin clay having an average particle size of 0.1 to 2.0 microns, and less than 0.1 weight percent titanium dioxide, said weight percents being based on the weight of the fiber, and a method for making the same. The polyamide fiber is particularly useful as a carpet fiber.
