摘要： A crimped polyester fiber which is made of a polytrimethylene terephthalate polyester, is three-dimensionally crimped so as to have a number of crimps of 9 to 30 per 25 mm and a percentage crimp of 20 to 50%, and has a crimp elasticity of 80% or higher; and a fibrous structure which comprises short fibers of the crimped polyester fiber and short heat-bondable composite fibers in a weight ratio of from 30/70 to 95/5 and in which at least part of the points where the two kinds of short fibers are in contact with each other and/or the points where the short heat-bondable composite fibers are in contact with each other have been thermally fixed.
