  Verfahren zur Herstellung   wollähnlicher   Kunstseide 
 EMI1.1 
 Spule befindliche überdrehte Garn bei 2   atü   während   !   Stunde gedämpft. Nach dem Trocknen wird das Garn über den Nullpunkt hinaus auf 50 Drehungen je Meter zurückgedreht und   hi   (uf im Strang mit einer Lösung von 200 cm3   40% igem   
 EMI1.2 
 60   C vorgetrocknet, während 10 Minuten auf 120   C erhitzt, abgeseift, gespült und nach Fertigstellung nochmals gedämpft. 



   Beispiel 2 : Die Behandlung ist dieselbe wie in Beispiel   1,   nur wird das Garn ausserdem nach dem Zurückdrehen über den Nullpunkt hinaus in   ungespanntem   Zustand gedämpft. 



   Beispiel 3 : Ungedrehte Kupferseidefäden vom Titer 120 den. werden auf 2500   Drehungen/m   gedreht und auf den Spulen während 40 Minuten bei 4   cM   gedämpft. Nach dem Trocknen werden die Fäden bis über den Nullpunkt aufgedreht und auf einer Schneidvorrichtung zu Stapelfaser zerschnitten. Nach dem Verspinnen wird das erhaltene Garn einer Formaldehydbehandlung gemäss Beispiel 1 unterworfen. 



   Beispiel 4 :   Kupferseidegam   vom Titer 150 den. mit der Drehungszahl   2oo/m   wird auf 2000 Drehungen/m überdreht. Hierauf wird das überdrehte Garn bei 5 atü während 20 Minuten gedämpft. Nach dem Trocknen wird das Garn auf der Zwirnmaschine aufgedreht und auf 80 Drehungen über den Nullpunkt hinaus gebracht. Nach dem Haspeln wird das Garn in Strangform wie oben gedämpft und anschliessend mit einer Lösung von 90 cm3 40% igem Formalin

  Process for the production of wool-like rayon
 EMI1.1
 Over-twisted thread on the bobbin at 2 atm Hour steamed. After drying, the yarn is twisted back past the zero point to 50 turns per meter and then in a strand with a solution of 200 cm3 of 40% strength
 EMI1.2
 Predried at 60 C, heated to 120 C for 10 minutes, soaped off, rinsed and steamed again after completion.



   Example 2: The treatment is the same as in Example 1, except that the yarn is also steamed in the untensioned state after it has been twisted back beyond zero.



   Example 3: Untwisted copper silk threads of 120 denier. are turned to 2500 revolutions / m and steamed on the reels for 40 minutes at 4 cM. After drying, the threads are untwisted above zero and cut into staple fibers on a cutting device. After spinning, the yarn obtained is subjected to a formaldehyde treatment according to Example 1.



   Example 4: Copper silk yarn with a denier of 150 denier. with the number of turns 2oo / m is over-turned to 2000 turns / m. The twisted yarn is then steamed at 5 atm for 20 minutes. After drying, the yarn is untwisted on the twisting machine and made 80 turns above zero. After reeling, the yarn is steamed in strand form as above and then with a solution of 90 cm3 of 40% formalin
