본 발명에 있어서는 저흡수성의 폴리아미드를 포함하는 섬유를 사용하고, 권축가공사가 가지는 신축성을 직편물에 있어서 적정하게 발현시키는 것이 가능한 신축성과 유연성을 부여하는 것이 가능한 폴리아미드 권축가공사를 제공한다. 본 발명의 폴리아미드 권축가공사는 온도 30℃, 상대습도 90% RH시의 평균 흡수율이 5% 이하인 저흡수성 폴리아미드를 적어도 40질량% 포함하고, 상기 저흡수성 폴리아미드를 한쪽의 성분으로 하는 사이드 바이 사이드형 복합사이며, 또한 가연가공되고 크림프 신장률이 25% 이상이다. 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.
