Description
Beim weiteren "Ausbau des Verfahrens nach der schweizerischen Patentschrift 94 666, insbesondere beim weiteren Ausbau des. Verfahrens zur Herstellung von Fäden aus fri-S scher, ungereinigter Viskose in neutralen bzw. schwachsauren Metallsalzbäderen nach der schweißerischen Patentschrift 87 368, ergibt sich, daß man um so leichter feine Kapillarfäden erzielen kann, je höher der Cellulosegehalt der zu verspinnenden Viskose gehalten wird. Besonders ist dies zutreffend, wenn die beiden vorerst genannten Verfahren kombiniert angewendet werden, also eine frische oder wenig vorgereifte Viskose in neutralen bzw. schwachsauren Metallsalzbädern zu dickeren Fäden versponnen und nach der Koagulierung, jedoch vor der Hydratisierung, gestreckt wird, wobei noch als besonderes Merkmal der Zellstoffgehalt derWith further "expansion of the process according to Swiss patent specification 94 666, in particular in the further expansion of the. Process for the production of threads from fri-S shear, unpurified viscose in neutral or weakly acidic metal salt baths the welding patent specification 87 368, it follows that it is all the easier for fine capillary threads can achieve the higher the cellulose content of the viscose to be spun will. This is particularly true when the two procedures mentioned above can be used in combination, i.e. a fresh or slightly pre-ripened viscose in neutral or weakly acidic metal salt baths into thicker threads and after coagulation, but before hydration, is stretched, with still as special feature of the pulp content of the
ao Viskose auf über io°/0, vorzugsweise auf 10 bis I5°/O gehalten wird.ao viscose is kept at over 10 ° / 0 , preferably at 10 to 15 ° / 0 .
Die so hergestellteKunstseide zeichnet sich durch besonders hervorragende textile Eigenschaften aus. Sie besitzt eine erheblichThe artificial silk produced in this way is characterized by particularly excellent textile properties the end. She owns a substantial
2^ größere Deckkraft, größere Weichheit und hat einen der echten Seide ähnlichen ruhigen Glanz. Auch läßt sich diese Seide mit den gebräuchlichen Farbstoffen erheblich gleichmäßiger anfärben. 2 ^ greater opacity, greater softness and a calm sheen similar to real silk. This silk can also be dyed much more evenly with the usual dyes.
Es ist zwar schon vorgeschlagen, Viskose mit einem Cellulosegehalt von über io°/0 zu verspinnen (s. Patentschrift 337672), doch bezog sich das besagte Verfahren auf die sonst übliche Arbeitsweise und auf die Erstellung von verhältnismäßig starken Kapillarfäden von 6 Denier und darüber.Although it has already been proposed to spin viscose with a cellulose content of over 10 ° / 0 (see patent specification 337672), the said process referred to the otherwise customary procedure and to the production of relatively strong capillary threads of 6 denier and above.
Auch die Herstellung feiner Fäden ist bereits mit französischer Patentschrift 511 823 beschrieben. Jedoch handelt es sich hier um das Verspinnen sehr reifer Viskose, während nach dem vorliegenden Verfahren frische, wenig vorgereifte Viskose verwendet wird. Mithin ist schon das Erfindungsmerkmal der französischen Patentschrift 511 823, welches — wie es im Anspruch heißt — in der Verwendung sehr reifer Viskose besteht, ein ganz anderes als das Erfindungsmerkmal der vorliegender Erfindung.The production of fine threads is also already covered by French patent specification 511 823 described. However, this involves the spinning of very ripe viscose while according to the present process, fresh, less premature viscose is used. Thus, the feature of the invention of the French patent specification 511 823, which - as it says in the claim - consists in the use of very ripe viscose quite different from the feature of the present invention.
Im übrigen wird der hervorragende technische Effekt nach vorliegender Erfindung durch die Kombination erreicht, daß man frische oder wenig vorgereifte Viskose in neutralen oder schwachsauren Metallsalzbädern zu Fäden verspinnt und den Faden nach der Koagulierung, jedoch vor der Hydratisierung, streckt, wobei der Zellstoffgehalt auf über io°/0 bzw. auf 12 bis I5°/O gehaltenIn addition, the excellent technical effect according to the present invention is achieved by the combination that fresh or slightly pre-ripened viscose is spun into threads in neutral or weakly acidic metal salt baths and the thread is stretched after coagulation, but before hydration, the pulp content being over io held ° / 0 and at 12 ° to I5 / O
