ete#ede de traütement de la cellulose en vue de la preparation de nasses visqueuses ou gelatineuses. cellulose treatment study for the preparation of viscous or gelatinous traps.
Cette invention se rapporte il un procetlc de traitetnent de la cellulose en vue de la preparation de tnasses visqueuses ou gelati neuses ä Base de cellulose. This invention relates to a process for the treatment of cellulose with a view to the preparation of viscous or gelatinous masses based on cellulose.
Selon ce procede, an traite la cellulose `elle que par exemple le coton, par au moins tine solntiott conteiiaiit ati moitis un thiocyanate. According to this process, year treats the cellulose `it that for example cotton, by at least tine solntiott conteiiaiit ati half a thiocyanate.
Quelques-uns des thiocyanates, tels quo par exemple les thiocyatiates de calcinm, de mangatiese, de strontium et de lithium, agi ront seins dune maniere satisfaisante. Dans d'autres cas,, an obtient des resultats satis faisants en employant au nioins deux thio cyanates combines, par exemple cetix obtenus en dissolvant des thiocyanates insolubles ou peti solubles dann 1'eaü dans des solutions de thioc3-anates facilenient solubles dass 1'eau; an peut encore employer des melanges d'un an de pltisietirs thioc3-anates en solution avee d'autres sels, tels que par exemple 1e chlorure de calcium, qui ne contrecarrent pas 1'action du ou des thioevanates et dort les solutions aqueuses ordinaires ne disolvent pas la cellu- Some of the thiocyanates, such as calcium, manganese, strontium and lithium thiocyatiates, for example, will work satisfactorily. In other cases, satisfactory results are obtained by employing at least two combined thiocyanates, for example those obtained by dissolving thiocyanates which are insoluble or sparingly soluble in water in solutions of easily soluble thiocyanates in water. water; one can also use one-year mixtures of thioc3-anate pltisietirs in solution with other salts, such as, for example, calcium chloride, which do not counteract the action of the thioevanate(s) and yet ordinary aqueous solutions do not do not dissolve the cellu-

11 est evident qn'ori peut aus"i einployer des soltitions obtetiues en nielangeant un ou plusieurs tliioc3-an.ites avec Taufres sels dont los solutions elles-inetiies sont des dissolvants de la cellulose. It is obvious that ori can also employ solutions obtained by mixing one or more tliioc3-an.ites with taufres salts, the solutions of which themselves are cellulose solvents.
Voici qnelques exemples niontrant de quelle tiiaiiiere 1e procede peut kre inis en ix t ivre. Here are a few examples showing what kind of process the process can be used for.
<I>E,eemple 1:</I> Un introduit 4 gr de coton ou d'une antre matiere celltilosiqne, de preferenee 't 1'etat sec, d < tris 100 ce d'une solution de tliio cyanate de calciuni, dort 1e poids specifique est de 1,38. La nielange est agite et cliauffe a <B>100"</B> G, teniperature que Fon maintient pendant une heure tont en agitant 1e me lange. Ensuite, an Wve la temperature a l'20" C et an ha niaintient a rette tempera ture jusqii':t ce que la cellulose soit entiere nient dissoute. <I>Example 1:</I> One introduces 4 g of cotton or another celltilosic material, preferably in the dry state, of < tris 100 cc of a solution of triio cyanate of calcium, sleeps the specific weight is 1.38. The mixture is agitated and heated to <B>100"</B> G, a temperature which is maintained for one hour while stirring the mixture. Then, the temperature rises to 20" C and the temperature is kept at a low temperature. temperature until the cellulose is fully dissolved.
<I>Exemple 2:</I> 4 Parties en poids de coton ou autre nia ti,-re cellulosique sont introduites dans 100 cc dune solution contenant 70 gr de thiocya nate de sodium et 70 gr thiocyanate mer eurique. 0n remue 1e melange et an 1e chauffe 2 100 C Pendant une heure, puis an eleve la teinperature ii 12W1 C. 0n inaintient 1e nielange ä. cette temperature jusqu'ä ce que la cellulose soit conipleternent dissoute. <I>Example 2:</I> 4 Parts by weight of cotton or other cellulosic nia ti,-re are introduced into 100 cc of a solution containing 70 g of sodium thiocyanate and 70 g of euric mer thiocyanate. The mixture is stirred and heated to 2100 C for one hour, then the temperature is raised to 1201 C. The mixture is left untouched. this temperature until the cellulose is completely dissolved.
<I>Exe-mple 3:</I> 0n verse 30 cc d'une solution de chlo rure de ealcium contenant <B>86</B> gr de Ca Ch pour 100 ce d'eau dann 70 cc d'une solution de thiocyanate de calcium contenant 76 gr de thioeyanate par 100 cc de liquide. Les deuz solutions sont bien melarigAes, ptris ori ajoute 4 gr de cellulose et 1'on souinet 1e mtaange au traiteinent decrit dans les ereni ples precederii.s. <I>Example 3:</I> 0n pours 30 cc of a calcium chloride solution containing <B>86</B> gr of Ca Ch per 100 cc of water into 70 cc of a calcium thiocyanate solution containing 76 gr of thioeyanate per 100 cc of liquid. The two solutions are well mixed, kneaded or added 4 g of cellulose and the mixture is mixed with the treatment described in the preceding examples.
Dans ces eiemples, la solution du oti des tliiocyanates ou d'un nielange de tliiocy anate et d'un autre sel peut etre acidulde au moyen d'acide aeetique que Fon peut ajouter dann la Proportion de 4 Parties en voluine d'acide acetique glacial ä 100 Parties en voltime de 1a solution. In these examples, the solution of the thiocyanates or of a mixture of thiocyanate and another salt can be acidulated by means of acetic acid which can be added in the proportion of 4 parts by volume of glacial acetic acid. to 100 voltime parts of the solution.
Le fait d'aciduler la solution contenant Je thiocy anate augniente, dune Part, 1e pou voir que possede cette solution de dissoudre la eellulose, lautre pari, il accelere la vitesse de dissolution; en d'autres ternies, un voluine donne de solution acidulee de thioeyanate dissout une plus Brande quantite de cellulose ei cela plus rapidement que si 1e meme vo lume n'etai% pas acidule. The fact of acidulating the solution containing the thiocyanate increases, on the one hand, the first power to see that this solution has to dissolve the cellulose, on the other hand, it accelerates the speed of dissolution; in other words, a given volume of acidulated thioeyanate solution dissolves a greater amount of cellulose and that more quickly than if the same volume were not acidulated.
Les solutions @t, base de cellulose obte nues par 1e procede decrit penvent servir comme enduit pour recouvrir des tissus, et a, la fabrication de fils ou de filainents. The solutions @t, based on cellulose obtained bare by the first process described penvent serve as a coating to cover fabrics, and a, the manufacture of son or filaments.
