Description
<EMI ID=1.1>
L'invention a pour objet un procédé pour la production de fils
<EMI ID=2.1>
selon lequel le colorant est incorporé au fil au cours même de l'opération de filage.
On sait que les fils de nitrile polyacrylique ne peuvent être teints qu'avec d'extrêmes difficultés. Le brevet allemand-NI' 716.152 pr opose bien une méthode pour la teinture des composés de phényle, d'acryle et de
<EMI ID=3.1>
trile polyacrylique est réalisée en ajoutant directement les colorants aux polymérisats avant le filage. Pour la coloration des filés, des colorants ap-

tion de 60% environ.
Les -leucoesters constituant des colorants pour la teinture à la cuve se prêtent également à l'emploi envisagé. Les solutions auxquelles est ajoutée la matière colorante sont filées comme d'ordinaire par le procédé de filage au sec. Les fils colorés obtenus peuvent être étirés et rétrécis;
<EMI ID=5.1>
Les colorants incorporés aux fils se distinguent par une grande adhérence et par une grande insensibilité à l'action de la lumière et de l'eauo Les exemples suivants éclairent plus complètement- l'invention.

The invention relates to a process for the production of yarns
<EMI ID = 2.1>
according to which the dye is incorporated into the yarn even during the spinning operation.
It is known that polyacrylic nitrile yarns can only be dyed with extreme difficulty. German patent-NI '716,152 does indeed provide a method for the dyeing of compounds of phenyl, acryl and
<EMI ID = 3.1>
Polyacrylic trile is made by adding the dyes directly to the polymerizates before spinning. For coloring the yarns, coloring agents

tion of about 60%.
The -leucoesters constituting colorants for tank dyeing are also suitable for the intended use. Solutions to which the coloring matter is added are spun as usual by the dry spinning process. The colored threads obtained can be stretched and shrunk;
<EMI ID = 5.1>
The dyes incorporated into the threads are distinguished by high adhesion and by high insensitivity to the action of light and water. The following examples more fully elucidate the invention.
<EMI ID = 6.1>
dyes by G. Schultz - 7th edition), content related to the amount of polymerizate. The solution is filtered, then, as usual, dry-spun
<EMI ID = 7.1>
can be stretched and shrunk and which, by their physical properties, are similar to uncolored yarns. Boiling and washing do not alter the tone of the color.
example 2.
<EMI ID = 8.1>
The green solution is added to 728 grams of polyacrylic nitrile, then the mixture is dissolved with heating and stirring. The green threads subsequently obtained by the dry spinning process have a high tenacity color.
Example 3.
Has a dimethylformamide spinning solution, which contains
<EMI ID = 9.1>
dry spinning, and the resulting yarns are subjected to the usual subsequent treatments. We obtain threads of a beautiful blue, the color of which has great resistance to the action of 1-water.
