PROCEDE, POUR EVITER LA DIMINUTION DE LA RESISTANCE AU DECHIREMENT DE MATIERES FIBREUSES PROVOQUEE PAR LEUR TEINTURE AVEC DES COLORANTS DE
SOUFRE.
On sait que la résistance au déchirement de matières contenant de la cellulose, comme le coton, la cellulose régénérée ou le lin, teintes avec des colorants de soufre, notamment avec du noir de soufre, diminue sensiblement par un emmagasinage assez long de la marchandise. La rapidité de cette diminution de la résistance au déchirement dépend du genre du co- lorant, de l'emmagasinage, des conditions atmosphériques comme la tempéra-. ture, l'humidité de l'air, l'exposition à la lumière, etc.
Or, la demanderesse a trouvé qu'on pouvait éviter cette dimi- nution de la résistance au déchirement en traitant les matières contenant de la cellulose, avant, pendant ou après la teinture avec des colorants de soufre, avec des solutions aqueuses de diamines ou polyamines aliphati- ques, notamment de celles ayant un poids moléculaire élevé.
Comme diamines de ce genre, on peut utiliser par exemple : l'éthylène-diamine, la propylène-diamine, l'hexaméthylène-diamine, des poly- mérisats de l'éthylène-imine, des produits de condensation de dihalogéno-al - coyles avec de l'ammoniaque, particulièrement leurs composants non distil- lables ou des produits d'alcoylation ou de peralcoylation de ces amines sous forme de bases libres, ou aussi des produits obtenus par réaction de ces diamines avéc des dihalogénures d'alcoyles., Exemple :
On teint, de façon normale, des écheveaux de coton avec un co- lorant de soufre, par exemple du carbone "Immédial CBO", et on les rince.
On traite une partie des écheveaux dans un bain contenant par litre 5 gr. d'un polymérisat d'éthylène-imine, on les froisse et on les rince 5 fois avec de l'eau distillée.
<Desc/Clms Page number 2>
Pour éprouver la résistance au déchirement qu'aurait, après un emmagasinage assez long, la matière fibreuse ainsi traitée, elle est sou- mise à un vaporisage, Inexpérience ayant démontré que le traitement de vapo- risage provoque une altération de la résistance au déchirement analogue à celle qui résulte d'un emmagasinage assez long.
Ensuite, on soumet à un vaporisage, de même durée, par exemple de 3 heures, les fibres teintes non traitées aussi bien*que les fibres tein- tes traitées avec l'éthylène-imine polymérisée. Après ce temps, la résis- tance au déchirement est déterminée sur la machine de déchirement "Schopper".
Lors de cette épreuve, il se révèle que les écheveaux teints mais non traités ultérieurement ont perdu 80 % de leur résistance au déchi- rement, tandis que les écheveaux teints et traités selon 1-'invention avec une polyalcoylène-polyamine n'ont perdu que 7,8% de leur résistance. Cette résistance au déchirement des écheveaux traités avec le polymérisat d9éthy-- lène-imine reste d'ailleurs inchangée, quand ils sont rinces plusieurs fois, lavés avec du savon, à 90 , et rincés encore à plusieurs reprises. Il est intéressant de constater.que même après une acidification subséquente avec de l'acide acétique et rinçage, la résistance au déchirement des écheveaux traités selon cet exemple est encore plusieurs fois plus grande que celle des écheveaux non traités.

PROCESS, TO AVOID THE REDUCTION OF THE RESISTANCE TO TEARING OF FIBROUS MATERIALS CAUSED BY THEIR DYING WITH COLORANTS OF
SULFUR.
It is known that the tear resistance of materials containing cellulose, such as cotton, regenerated cellulose or flax, dyed with sulfur dyes, in particular with sulfur black, decreases appreciably by a fairly long storage of the goods. The rapidity of this decrease in tear strength depends on the kind of dye, storage, atmospheric conditions such as temperature. ture, humidity, exposure to light, etc.
Now, the Applicant has found that this reduction in tear resistance could be avoided by treating the materials containing cellulose, before, during or after dyeing with sulfur dyes, with aqueous solutions of diamines or polyamines. aliphatic, especially those having a high molecular weight.
As diamines of this type, there may be used, for example: ethylene diamine, propylene diamine, hexamethylenediamine, poly- merisates of ethyleneimine, condensation products of dihalo-alkyls. with ammonia, particularly their non-distillable components or products of alkylation or peralkyllation of these amines in the form of free bases, or also products obtained by reaction of these diamines with alkyl dihalides. :
Cotton skeins are normally dyed with a sulfur dye, for example "Immediate CBO" carbon, and rinsed.
Part of the skeins are treated in a bath containing 5 gr per liter. of an ethyleneimine polymerizate, crumpled and rinsed 5 times with distilled water.
<Desc / Clms Page number 2>
In order to test the resistance to tearing which the fibrous material thus treated would have after sufficiently long storage, it is subjected to vaporization, experience having shown that the vaporization treatment causes a deterioration in similar tear resistance. to that which results from a rather long storage.
The untreated dyed fibers as well as the dyed fibers treated with polymerized ethylene imine are then subjected to spraying for the same duration, for example 3 hours. After this time, the tear strength is determined on the "Schopper" tear machine.
In this test, it turns out that the skeins dyed but not subsequently treated have lost 80% of their tear resistance, while the skeins dyed and treated according to the invention with a polyalkylene polyamine have lost only 7.8% of their resistance. This resistance to tearing of the skeins treated with the ethyleneimine polymerizate moreover remains unchanged when they are rinsed several times, washed with soap at 90 °, and rinsed again several times. Interestingly, even after subsequent acidification with acetic acid and rinsing, the tear resistance of the skeins treated according to this example is still several times greater than that of the untreated skeins.
