    摘要： A process for manufacturing cellulose fibers or yarns with a reduced tendency to form fibrils includes treating fibers or yarns, which are washed after the filament forming process but not yet dried, with a cross-linking agent. The process includes treating the fibers or yarns with reactive polysiloxanes which are modified with amino, polyalkylene oxide, epoxy or carboxyl functional groups and which cross-link with themselves. The process is particularly suitable for fibers produced according to the NMMO process.
