Abstract
The present invention provides a crimped polyamide yarn to which it is possible, using fibers that include low water absorption polyamide, to impart a stretch property and pliability such that it is possible for the inherent stretch properties of the crimped yarn to be appropriately expressed in a woven or knit fabric. The crimped polyamide yarn of the present invention is a side-by-side composite yarn which includes at least 40 mass % of low water absorption polyamide having an average of water absorption ratio of 5% or less at a temperature of 30° C. and a relative humidity (RH) of 90%, and in which the low water absorption polyamide is at least one component. The yarn is false-twisted, and has a crimp elongation ratio of 25% or more.
