Abstract
The absorbency of regenerated viscose filaments is improved by overfeeding a continuous tow of partially regenerated filaments onto a moving foraminous support so that regeneration occurs prior to and after the filament tow is overfed onto the moving support.
Claims8
In a process for improving at least one property of a continuous filament tow of regenerated viscose cellulose filaments in which process a running tow in a flowing liquid in the form of a spread band is overfed onto a moving foraminous support to separate it from the liquid, so as to form a coherent web, which web is dried, the improvement of having the continuous filament tow of cellulosic viscose filaments in the partially regenerated state when it is overfed onto the moving foraminous support so that the regeneration of the partially regenerated viscose occurs prior to and after the filament tow is overfed onto the moving foraminous support.
A process as claimed in claim wherein the web is kept in the overfed state during drying.
