in Gewichtsprozent= 1,26/ + 8 ±3,in percent by weight = 1.26 / + 8 ± 3,

verknüpft ist, gemäß Patent 971 618, dadurch gekennzeichnet, daß eine Viscose mit einem höheren /-Wert bei gleicher Säurekonzentration in ein wärmeres Bad versponnen wird.is linked, according to patent 971,618, thereby characterized in that a viscose with a higher / value at the same acid concentration is spun in a warmer bath.

2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß ein Bad mit einer Säurekonzentration von 66% verwendet und eine Viscose versponnen wird, deren Xanthogeniergrad bei den nachstehend genannten Temperaturen die optimalen Werte hat:2. The method according to claim 1, characterized in that that a bath with an acid concentration of 66% is used and a viscose is spun, its degree of xanthation has the optimal values at the following temperatures:

bei 20° C: / = 46 bei 230C: / = 48 bei 300C: y = Si bei 400 C: / = 54at 20 ° C: / = 46 at 23 0 C: / = 48 at 30 0 C: y = Si at 40 0 C: / = 54

3. Verfahren nach Anspruch 2, dadurch gekennzeichnet, daß identische Temperaturänderungen entsprechend den Kurven für eine gleiche Änderung des optimalen /-Wertes, der einer anderen Schwefelsäurekonzentration entspricht, vorgenommen werden.3. The method according to claim 2, characterized in that identical temperature changes according to the curves for the same change in the optimal / value, which corresponds to a different sulfuric acid concentration, be made.
