Abstract
Crimped polyester fibers which comprise a polytrimethylene terephthalate-based polyester and have three-dimensional crimps with a number of crimps of 9 to 30 peaks/25 mm and a crimp ratio of 20 to 50% and further a crimp modulus of elasticity of 80% or above. A fiber structure wherein the weight ratio of staple fibers of the above crimped polyester fibers to heat-bonding conjugated staple fibers is 30:70 to 95:5 and heat-bonded spots are formed at least partially in contact points of both the staple fibers and/or contact points of the mutual heat-bonding conjugated staple fibers.
