Procédé pour donner aux matières fibreuses un apprêt résistant qu lavage.
On sait que l'on apprête. lesmatières fibreuses au moyen, de sels alcalins d'acides algéniques. En particulier, on a déjà employé l'alginate de sodium à titre d'agent d'encollage et.d'apprêt. Cependant, cet agent s'élimine facilement au lavage et par suite ne permet pas d'obtenir un apprêt résistant à l'eau.
Or, on a découvert qu'on peut réaliser un excellent apprêt pour matières fibreuses résistant au lavage, en faisant agir, outre les sels alcalins des acides algéniques, en même temps ou dans un ordre de succession quelconque,des sels 'solubles dans l'eau, qui forment avec' l'alginate de sodium des composés insolubles dans l'eau.
Bien entendu, les sels à envisager d'une manière générale sont ceux qui donnent avec les alginates alcalins des produi ts de réaction incolores. Pratiquement , les sels à en-

visager en premier lieu sont les sels de ; iagn&i,ii>;: et d'alW;lÍlJiU1l1 ainsi que les sels alcalino-tûi'reux, eu particulier les sels de calcium. Suivant l'effet qu'on délire obtenir, on emploie de 5 00 ; ':,1 ;i!za'e alcalin par litre d'eau.
La proportion de sels provoquant la l'réciI11tation est plus faible que la quantité dtxliinafe alcalin et il convient d'en calculer la îû:ui té de façon qu'il ne subsiste dans la matière aucun excès notable du sol de pré- cipitation. La proportion à adopter alors du sol de @réci- pitation est facile à déterminer par des essais préliminaires dans chaque cas particulier.
Exemple l.
On imprègne une serge en rayonne avec une solu-

mentatioll de poids d'environ 1C0). On fait t alors Lu tissu un premier séchage eton l'imprègne avec une selution de 3 g. de chlorurede calcium par litre d'eau eton le sèche de nouveau. La serge en rayonne ainsi traitée possède un apprêt satisfaisant, qui se conserve d'une manière absolue, même apres un traitement a plusieurs reprises par l'eau, les bains de lavage au sevon et les bains de lavage neutres.

Puis on sèche le tissu sur un cadre tendeur. On obtient ainsi un tissu possédant un excellent apprêt résistant complètement à l'eau etan lavage.

Exemple 3.
On imprègne une serge en rayonne avec une solution de 2g. par litre de chlorure de magnésium, on presse à 100%, on fait subir un premier séchage, puis on imprègne avec une solution de 10g. d'alginate de sodium par litre d'eau et on sèche de nouveau.

A process for giving fibrous materials a wash resistant finish.
We know we're getting ready. the fibrous materials by means of alkali salts of algenic acids. In particular, sodium alginate has already been used as sizing and finishing agent. However, this agent is easily washed off and therefore does not provide a water resistant finish.
Now, it has been discovered that an excellent finish for fibrous materials resistant to washing can be produced by causing, in addition to the alkali salts of algenic acids, at the same time or in any order of succession, salts soluble in the water to act. water, which together with sodium alginate form water-insoluble compounds.
Of course, the salts to be considered in general are those which give colorless reaction products with the alkali metal alginates. In practice, the salts in-

face in the first place are the salts of; iagn & i, ii> ;: and alW; lÍlJiU1l1 as well as the alkaline-tûi'rous salts, in particular the calcium salts. According to the delirious effect to obtain, one employs 5 00; ':, 1; i! Za'e alkaline per liter of water.
The proportion of salts causing the shrinkage is lower than the amount of alkali metal and the amount should be calculated so that no substantial excess of the precipitation soil remains in the material. The proportion to be adopted then of the recuperation soil is easily determined by preliminary tests in each particular case.

mentatioll of weight of about 1C0). The fabric is then dried for the first time and it is impregnated with a salt of 3 g. of calcium chloride per liter of water and it is dried again. The rayon twill thus treated has a satisfactory finish which is absolutely preserved even after treatment several times with water, wash baths and neutral wash baths.
