Abstract

Mfr. of composite crinkling fibres having a core eccentric in the surrounding sleeve comprises feeding one polymer constituent under press to a nozzle and introducing a second stream as a core into the same nozzle; a portion of the first stream is branched off, the first two streams are jointed side by side and the branched steam is used to form a sleeve around them.
