Néanmoins, dans le .procédé objet de la présente invention, la destruction du pigment azorque rongeable est effectuée même dans irtintéri- 'eux' de la fibre. On peut éliminer complètement les rongeant par le'traitement ultérieur usuel avec des'bains alcalins chauds.
Si l'on'ajoute aux pâtes d'impression rongeables des colorants résistant au rongeage, par exemple,des colorants de cuve ou des colorants basiques ou substantifs doués de cette propriété, on peut enluminer les rongeages. Par l'addition de' mouillants ou

He proceeded to rearing and fibrous material / by this process. "It is known that, by printing reductive rearing pastes

oe and containing sodium far3ialâhyde-su.foxy.ate, 1.ta.sali and a thickener and by subsequent spraying, yarns or fabrics of natural or regenerated cellulose, which have been dyed, can be gnawed in white. with the aid of rable ice dyes. In the same way, colored removals are obtained, if, to the.tén.evae products operating by reduction, dyes resistant to gnawing are added, for example vat dyes that set during spraying.
However, the Applicant has found that it is possible to obtain
EMI1.3
white and colored blankets if the gnawing print pastes mentioned above are printed on the fibrous material or regenerated cellulose which has been colored during spinning with

'of. rongeable azole pigments and if the material thus treated is subjected to vaporization.

qte.;, during the usual coloring, it remains localized mainly in the outer layers of the fiber. However, in the process which is the subject of the present invention, the destruction of the gnawable azorque pigment is carried out even within the interior of the fiber. The gnawing can be completely removed by the usual subsequent treatment with hot alkaline baths.
If gnaw-resistant dyes, for example, vat dyes or basic or substantive dyes having this property are added to the gnawing printing pastes, the gnawings can be illuminated. By adding 'wetting agents or
