Abstract

A process for the production of fibre structures comprises treating conjugate fibres with organic solvent the fibres being shrinkable and unfixed and having at least two incompatible polymer components which show different shrinkage behaviour in the solvent and which are arranged in the fibre cross-section in the form of a matrix and segments (see for example Figs. 2, 5 and 7), the segments occupying from 20 to 80% of the total cross-section and at least three segments being peripherally arranged and the solvent being a liquid or gaseous organic solvent which reduces the zero shrinkage temperature of the matrix polymer or of the segment polymer by at least 160 DEG C. Various fibre structures are also disclosed. <IMAGE> [GB2015421A]
