   Die bei der Hydratisierung zu   beobachtenden Temperaturen   wurden schon oben im   allgemeinen   festgelegt. Auch hier sind engere Grenzen bestimmt worden, die zu einem noch   bessetCn Endergebnis   fuhren.

   Bei Einhaltung des vorgeschriebenen Laugegewichts der Alkalizellulose und der Temperaturen. welchen diese bis zu   ihrer Behandlung mit Schwefelkohlenstoff ausgesetzt   bleibt, erhält das   Gespinst   die ursprünglichen Eigenschaften des Zellstoffes in fast unvermindertem Masse. Es   ve@bindet mit einem   milden Wolleglanz eine   Reissfestigkeit,   die   50% höher ist als diejenige der hochglänzenden   Kunstseide

 reichlich 50% seiner Trockenfestigkeit, gegen etwa 30% bei Kunsteide. Die Nassfestigkeit zeigt also eine absolute Überlegenheit von mehr als 100% gegenber Kunstseide. 



   Die vorstehend behandelten Punkte sind im Rahmen des   neuen     Verfahrens von wesentlicher   Bedeutung.

 EMI3.1
   Dissolution by means of water containing lye is less complete: on the other hand, the pulp parts that are inadvertently dissolved during the treatment with carbon disulfide in the presence of an excess of caustic soda, which have already undergone extensive decomposition under the influence of the heat of reaction that occurs during this treatment, have a disadvantage on the quality of the viscose solution and the web produced from it.



   The temperatures to be observed during hydration have already been generally specified above. Here, too, narrower limits have been set which lead to an even better end result.
 EMI3.2
 solution and the quality of the mind made from it unfavorably influenced.



   If the prescribed weight of alkali cellulose and the temperatures are observed. to which this remains exposed until it is treated with carbon disulfide, the web retains the original properties of the cellulose to an almost undiminished extent. With a mild wool sheen, Es ve @ has a tensile strength that is 50% higher than that of the high-gloss artificial silk
 EMI3.3
 50% of its dry strength, compared to about 30% for artificial silk. The wet strength shows an absolute superiority of more than 100% compared to rayon.



   The points discussed above are essential to the new process.
