La présente invention a pour objet un nouveau procédé chimique-physique permettant d'éliminer la main d'oeuvre

On procède, plus précisément, de la manière suivante :

<EMI ID=6.1>
(3 à 5 jours, de préférence). On procède ensuite au broyage mécanique des tiges complètement desséchées, par exemple au moyen de broyeuses à cylindres cannelés ou de machines analo- gues permettant l'élimination des parties ligneuses et d'une partie de l'écorce. On obtient ainsi des filasses que l'on passe au teillage mécanique au moyen, par exemple, de teilleuses à lin ou de moulins flamands, On procède ensuite au dégommage qui, à titre d'exemple, peut être exécuté de la manière suivante : Les filasses provenant du teillage, sont trempées,pendant 12 heures environ, dans de l'eau à la température ordinaire : ensuite on les passe dans une solution de chlorure de chaux à un pourcentage approprié.

(alcools ou acides gras sulfonés, etc.), où elles doivent rester assez longtemps (2 à 10 jours, par exemple) suivant le degré de souplesse que l'on veut obtenir. On lave ensuite les fibres dans de l'eau naturelle et on les passe au séchage. On obtient ainsi des fibres parfaitement blanches, très

Le dégommage et le blanchissage, dans le but d'éliminer toute substance non cellulosique, peuvent être réalisés, en dehors de la méthode ci-dessus indiquée, aussi par une méthode employant des peroxydes, des persels, ou des substances réductrices.

In the same way we extract from other urticated plants

The present invention relates to a new chemical-physical process for eliminating labor

fiber traction is done mechanically thanks to deséoha-
complete prior aging of the stems.
We proceed, more precisely, as follows:
<EMI ID = 5.1> pretreatment with substances derived from sulfonated fatty alcohols, or sulfonated fatty acids, or other products having detersive and impregnating properties, are completely dried by maintaining them at a temperature.
<EMI ID = 6.1>
(3 to 5 days, preferably). The completely desiccated stems are then mechanically crushed, for example by means of grinders with grooved rolls or similar machines allowing the removal of woody parts and part of the bark. In this way, yarns are obtained which are passed to mechanical scutching by means, for example, of flax scutching machines or Flemish mills, We then proceed to degumming which, by way of example, can be carried out as follows: Yarns from scutching are soaked for about 12 hours in water at room temperature: then they are passed through a solution of chloride of lime at an appropriate percentage. Some

<EMI ID = 8.1>
The degumming and the laundering, with the aim of eliminating any non-cellulose substance, can be carried out, apart from the method indicated above, also by a method employing peroxides, persalts, or reducing substances.
