摘要： A had comprising crimped bi- or multicomponent fibres consisting of at least two sections, which comprise a polymer or polymer blend as a predominant component and which are arranged across the cross-section of the fiber to promote crimping of the fibre during the setting process and which predominant components differ in. the crystallisation beat (dHc). The difference in the crystallisation heat (dHc) is in the range from 30 J/g to 5 J/g, and the predominant components differ in at least one of the other parameters selected from the group of melt flow index, degree of polydispersion and flexural modulus, while the relative difference of the predominant components is: for the flow index in the range from 100 g/10 min to 5 g/10 min and/or for the degree of polydispersion less than 1, but above 0.3, and/or for the flexural modulus in the range from 300 MPa to 50 MPa; where the relative difference in the melt flow index is not greater than 100 g/10 min, the degree of polydispersity is less than 1, the crystallisation heat is not greater than 300 Mpa. The fibres have the degree of crimping at least 5 crimps per 20 mm of fibre.
