de support de façon à permettre d'effectuer le traitement, des filaments. par la substance modifiant le lustre à toute distance désirée de. la face de la filière.

  
En quittant la mèche ou dispositif équivalent,

  
les. filaments continuent leur trajet à travers, le milieu évaporatoire et peuvent être conduits, à un dispositif de bobinage ou de moulinage, de préférence disposé à l'extérieur de la chambre ou. cellule.

  
Parmi les dérivés, cellulosiques qui peuvent constituer la base des solutions de filage, on citera les. formate., propionate- ou butyrate de cellulose, les, esters thio-

By leaving the wick or equivalent device,

  
the. filaments continue their path through the evaporative medium and can be led to a winding or milling device, preferably disposed outside the chamber or. cell.

  
Among the cellulosic derivatives which can constitute the base of the spinning solutions, there will be mentioned. cellulose formate., propionate- or butyrate, thio- esters
