PROBLEM TO BE SOLVED: To provide a low-modulus crimped yarn good in elastic recovery, excellent in product grade, satisfying various properties including medicament carrying capacity, chemical resistance and hydrolysis resistance, and having practical durability as well, and to provide a fiber structural product and a plaster comprising the crimped yarn. SOLUTION: The crimped yarn comprises sheath/core-type conjugate fibers with the sheath component consisting of polytrimethylene terephthalate and the core component consisting of a polyester except polytrimethylene terephthalate, wherein the weight fraction of the core component is 20-40 wt.% and the modified cross-section degree of the single filament is 1.5 or less.
