Description
Procédé pour rendre aptes<B>à</B> la teinture des corps en acétate de cellulose. L'acétate de cellulose n'étant pas per méable<B>à</B> l'eau, il est difficile de teindre par les procédés ordinaires les pellicules ou au tres articles<B>à</B> base d'acétate; les teintures (11.1,011 obtient sont claires et mal unies.
Or, il a été constaté qu'on peut rendre les objets en acétate de cellulose aptes<B>à</B> recevoir la teinture en les traitant par un bain ren fermant du phosphate trisodique. <I>Exemple:</I> Une pellicule en acétate de cellulose est pendant #\J, d'heure dans 20 litres dun bain renfermant du phosphate trisodique ob tenu cri mélangeant par litre<B>25</B> gr de phos phate de soude cristallisé, (phosphate diso- dique)
et<B>à</B> cm' de soude caustique<B>à 36 '</B> Bauni(l. On maintient ce bain entre<B>60</B> et <B>70 '</B> pendant toute la durée de l'opération.
La pellicule est ensuite bien rincée et sé- cliée; la perte de poids est de<B>6</B> %. Le procédé qui fait l'objet de la présente invention peut du reste être combiné avec la teinture elle-même, de façon que tout se passe dans un bain unique.
L'acétate traité au phosphate trisodique peut, d'autre Êart, être mordancé au tannin et<B>à</B> l'émétique avant qu'on applique le bain de teinture.
Process for making <B> </B> suitable for dyeing cellulose acetate bodies. Since cellulose acetate is not permeable <B> to </B> water, it is difficult to dye films or other <B> </B> acetate-based articles by ordinary methods. ; the dyes (11,111 obtained are clear and poorly united.
Now, it has been observed that objects made of cellulose acetate can be made suitable <B> to </B> receive the dye by treating them with a bath containing trisodium phosphate. <I> Example: </I> A cellulose acetate film is for # \ J, hour in 20 liters of a bath containing trisodium phosphate obtained cry mixing per liter <B> 25 </B> gr of phos crystallized sodium phate, (disodium phosphate)
and <B> to </B> cm 'of caustic soda <B> to 36' </B> Bauni (l. This bath is maintained between <B> 60 </B> and <B> 70 '</ B > throughout the operation.
The film is then rinsed well and separated; the weight loss is <B> 6 </B>%. The process which is the object of the present invention can moreover be combined with the dyeing itself, so that everything takes place in a single bath.
Acetate treated with trisodium phosphate may, in the other hand, be etched with tannin and <B> with </B> emetic before applying the dye bath.
