ABSTRACT OF THE DISCLOSURE A process for the production of fibre structures which comprises treating shrinkable substantially unfixed multicomponent fibres having at least two incompatible components arranged in the form of a matrix and several segments in the fibre cross-section, the segments occupying from 20 to 80% of the total cross-section and at least three-segments being peripherally arranged without complete envelopment by the matrix components, with a liquid or gaseous organic shrinkage-initiating agent effective to shrink said polyester, which reduces the zero shrinkage temperature of the matrix polymer or of the segment polymer by at least 160°C. and in which the polymer components forming the fibres show different shrinkage behaviour is disclosed; the process of the invention provides fibre structures in which the splitting produces a soft texture and ?l, similar to silk, additionally the structures provide good wearing comfort is that they have a high water retention capacity.
