Procédé pour rendre la laine irrétrécissable.
Les procédés, intéressants du point de vue industriel qui visent à rendre la laine irrétrécissable, reposent sur le traitement de la laine par le chlore. On fait agir, par exemple, des solutions'acides de chlore, à une température de 25 à 30 , sur la matière humectée au préalable, ou bien on traite la matière à l'état sec par le chlore gazeux. Lorsqu'on procède ainsi, on parvient à changer partiellement la struc- ture superficielle de la laine et à supprimer la tendance au feutrage de la laine, mais ce mode opératoire entraine un certain préjudice à la fibre ; outre, la laine roussit for- tement.
Récemment, on a découvert un procédé visant le trai-

tement de la laine, dans des solvants organiques, par du chlorure de sulfuryle. De cette manière, on réalise des effets similaires à ceux du procédé décrit plus haut, sans infliger de préjudice notable à la fibre.
La demanderesse a trouvé, maintenant, qu'on peut traiter la lama, egalement sans préjudice, et cela sans devoir recourir à des solvants organiques, lorsque, au lieu d'utiliser des solutions de chlore, on se sert de solutions d'hydrate de chlore.
On obtient une solution d'hydrate de chlore (C12.8H20) de la manière la plus simple en introduisant du chlore dans l'eau à température inférieure à 8 .
E x e m p l e
Dans de l'eau à 6 C, on introduit du chlore jusqu'à c e que la teneur en chlore actif s'élève à un gramme au litre. à l'aide de la solution d'hydrate de chlore ainsi'obtenue, on traite pendant 15 à 20 minutes de la laine, bien nettoyée, à des températures inférieures à 8 et en observant, entre lu laine et le bain, un rapport de 1:20; ensuite on rince cette laine à l'eau, à la même température, et on l'achevé de la maniere usuelle en la traitant par le bisulfite, etc. La laine ainsi traitée ne roussit pas, elle présente le toucher caractë- ristique de soie et elle est irrétrécissable. Pratiquement, 18 fibre ne subit aucun préjudice.

Process for making wool non-shrink.
The methods, interesting from an industrial point of view, which aim to make the wool non-shrinkable, are based on the treatment of wool with chlorine. Chlorine acid solutions, for example, are allowed to act at a temperature of 25 to 30 on the pre-wetted material, or the material in the dry state is treated with chlorine gas. When this is done, it is possible to partially change the surface structure of the wool and to eliminate the tendency to felting the wool, but this procedure causes some damage to the fiber; in addition, the wool scorches strongly.
Recently, a method has been discovered for the treatment
<Desc / Clms Page number 2>
ment of wool, in organic solvents, with sulfuryl chloride. In this way, effects similar to those of the process described above are achieved without inflicting significant damage on the fiber.
The Applicant has now found that lama can be treated, also without prejudice, and without having to resort to organic solvents, when, instead of using chlorine solutions, solutions of chlorine hydrate are used. chlorine.
A solution of chlorine hydrate (C12.8H20) is obtained in the simplest way by introducing chlorine into the water at a temperature below 8.
E x e m p l e
Chlorine is introduced into water at 6 C until the active chlorine content rises to one gram per liter. with the aid of the chlorine hydrate solution thus obtained, the wool is treated for 15 to 20 minutes, well cleaned, at temperatures below 8 and observing, between the wool and the bath, a ratio of 1:20; then this wool is rinsed with water, at the same temperature, and it is finished in the usual way by treating it with bisulphite, etc. The wool thus treated does not scorch, it has the characteristic touch of silk and is non-shrinkable. Practically, 18 fiber is not damaged.
