PROBLEM TO BE SOLVED: To provide a moisture sensitive crimped conjugated fiber whose percentage of crimp increases by drying and decreases by absorbing moisture when used in woven and knit fabrics. SOLUTION: The moisture sensitive crimped conjugated fiber comprises a conjugated fiber consisting of a sulfonate group-containing modified polyethylene terephthalate and a polyalkylene glycol-containing nylon which are conjugated side by side and has≥12% value calculated by subtracting the percentage of crimp after standing the crimped conjugated fiber in an atmosphere of 30°C temperature and 90% humidity for 2 hours from the percentage of crimp after drying the same at 60°C for 30 minutes. Preferably, the modified polyethylene terephthalate is a copolymer containing 1-7 mole % 5-sodium sulfoisophthalate and the nylon contains 1-20 wt.% polyalkylene glycol having≥1000 average molecular weight.
