 EMI2.1 
 nachbehandeltem Zustand durch Auftreten von ungleichem Glanz und trüben Streifen gekennzeichnet ist. Gibt man derselben Viskose einen Zusatz von   0#20% des Natriumxanthates   des Phenyläthylalkohols und spinnt unter genau gleichen Bedingungen, so erhält man eine Seide, bei der alle Stränge einwandfrei sind. Unter einer Viskose mit der Kochsalzreife   7%   wird eine Viskose verstanden, welche in einer 7¸%igen NaCl-Lösung gerade zur Koagulation gebracht werden kann, in einer   7Y4%igen   aber noch nicht. 



   2. Eine Viskose aus ungereifter Alkalicellulose mit 6-6¸% Zellstoff, 6¸% Alkali und einer hohen Viskosität gibt beim Spinnen in ein Bad mit   27% NaSO, 3% ZnSO   und   11% HLSO4   bei fast allen praktisch in Frage kommenden Reifen eine glanzlose, unansehnliche Seide. Gibt man der Viskose aber einen Zusatz von 0'25% Fenchylxanthat und spinnt bei der Reife   5%, so   erhält man glänzende Seide. 
 EMI2.2 
 normale glänzende Seide erhalten. 



   4. Eine Viskose wie in Beispiel 1, jedoch mit der Reife 5 und einem Gehalt von   0'4% Borneol-   
 EMI2.3 
 und 12% H2SO4 bei 30-35  koaguliert. Die entstandene Folie ist nach der Entschwefelung glasklar, während ohne den Zusatz nur trübe, beinahe undurchsichtige Produkte entstehen. 



   Die erfindungsgemäss verwendeten Xanthate aromatischer, hydroaromatischer, cyclischer und heterocyclischer Alkohole können nach Bemberger und Lodther (Bericht 23, Seite 213) sowie auch nach Hermans (Rec. des trav. chimiques des Pays-Bas, Band 45,4. Serie, 499,1926) hergestellt werden. 



   Das in den Beispielen 3 und 4 verwendete   Borneolxantliat   wird beispielsweise nach folgender Vorschrift erhalten : 
 EMI2.4 
 und zunächst unter   Kühlung,   später durch Kochen auf dem Wasserbad unter Rückfluss in das Xanthat übergeführt, das als   weissgelbe   Kristallmasse ausfällt und ohne Schwierigkeit abfiltriert und mit Äther ausgewaschen werden kann.

 EMI2.1
 post-treated condition is characterized by the appearance of uneven gloss and cloudy stripes. If one adds 0 to 20% of the sodium xanthate of the phenylethyl alcohol to the same viscose and spins under exactly the same conditions, a silk is obtained in which all strands are perfect. A viscose with a saline maturity of 7% is understood to mean a viscose which can just be made to coagulate in a 7¸% NaCl solution, but not yet in a 7Y4% solution.



   2. A viscose made from unripened alkali cellulose with 6-6¸% pulp, 6¸% alkali and a high viscosity gives a bath with 27% NaSO, 3% ZnSO and 11% HLSO4 in almost all practically possible tires Dull, unsightly silk. But if the viscose is given an addition of 0.25% fenchyl xanthate and 5% is spun when it is ripe, the result is shiny silk.
 EMI2.2
 normal shiny silk received.



   4. A viscose as in Example 1, but with maturity 5 and a content of 0'4% borneol
 EMI2.3
 and 12% H2SO4 coagulated at 30-35. The resulting film is crystal clear after desulfurization, while without the addition only cloudy, almost opaque products are created.



   The xanthates of aromatic, hydroaromatic, cyclic and heterocyclic alcohols used according to the invention can according to Bemberger and Lodther (report 23, page 213) and also according to Hermans (Rec. Des trav. Chimiques des Pays-Bas, volume 45, 4th series, 499, 1926 ) getting produced.



   The borneol xanthate used in Examples 3 and 4 is obtained, for example, according to the following procedure:
 EMI2.4
 and converted into the xanthate, initially with cooling, later by boiling on a water bath under reflux, which precipitates as a white-yellow crystal mass and can be filtered off without difficulty and washed out with ether.
