A method is disclosed of producing cellulose fibres or yarns with a reduced tendency to form fibrils. This is done by treating fibres or yarns which have undergone washing after the yarn-forming process but are not yet dried with a cross-linking agent; the fibres or yarns are treated using amino-, polyalkylene oxide, epoxy- or carboxyl functionally modified reactive polysiloxanes which are subjected to a self-cross linking. The process is especially suitable for use with fibres manufactured by the N-methylmorpholine- N-oxide (NMMO) process.
L'invention concerne un procédé de fabrication de fibres ou de fils de cellulose présentant une propension réduite à la formation de fibrilles. Ledit procédé consiste à traiter les fibres ou les fils lavés après le processus de formation de fils mais non encore séchés, avec un agent de réticulation. Selon ce procédé, on traite les fibres ou les fils avec des polysiloxanes réactifs modifiés fonctionnellement par amino, oxyde de polyalkylène, époxy ou carboxyle, les polysiloxanes étant soumis à une auto-réticulation. Ce procédé peut être utilisé en particulier pour les fibres fabriquées selon le procédé au NMMO (N-méthylmorpholine-N-oxyde).
