Description
Najdluzszy czas ttwahia patentu do 9 listopada 1950 r* Patent polski Nr 22 391 dotyczy sposo¬ bu przedzenia z wyciaganiem, polegajace¬ go na stosowaniu dwóch kapieli koagulu- jacych, przyczem wychodzaca z pierwszej kapieli nitke, która nie jest jeszcze zupel¬ nie skoagulowana, poddaje sie wyciaganiu, a w drugiej kapieli koagulujacej, w której nastepuje calkowita koagulacja nitki, za¬ chodzi swobodne kurczenie sie tej nitki.Wedlug patentu Nr 22 391 nitka po wyjsciu z drugiej kapieli koagulujacej zo¬ staje nawinieta na szpule.Sposób wedlug wynalazku niniejszego rózni sie od sposobu wedlug patentu Nr 22 391 tern, ze nitke po wyjsciu z dru¬ giej kapieli koagulujacej zwija sie w zwój w wirówce przedzalniczej.Na rysunku przedstawiono urzadzenie do wykonywania sposobu wedlug wynalaz¬ ku. Roztwór wiskozy przetlacza sie w spo¬ sób zwykly przez dysze przedzalnicza do kapieli koagulujacej /, skad plastyczna nit¬ ka przechodzi po walku /, obracajacym sie z szybkoscia obwodowa Vr Nastepnie nitka przechodzi miedzy elastycznemi wa¬ leczkami 2 — 2, obracajacemi sie z szyb¬ koscia V2 Vlf a nastepnie przechodzi do kapieli koagulujacej //. W kapieli // nicma moznosc zupelnie swobodnego kurcze¬ nia sie; z tej kapieli nitka po waleczkach prowadniczych 3 — 3 i walcu 8, obracaja¬ cym sie z szybkoscia V., < V2, przechodzi do wirówki przedzalniczej 9.Na rysunku cyfra 4 oznaczono filtr wi¬ skozowy, cyfra 5 — rurke, doprowadzaja¬ ca wiskoze, cyfra 6 — nitke naprezona, cy¬ fra 7 — nitke nienaprezona. PLThe longest period of the patent until November 9, 1950. Polish Patent No. 22,391 concerns the method of a pull-out interval, consisting in the use of two coagulation baths, with a thread emerging from the first bath, which is not yet completely coagulated, is subjected to stretching, and in the second coagulation bath, in which the thread completely coagulates, the thread shrinks freely. According to patent No. 22,391, the thread is wound on spools after leaving the second coagulation bath. The method according to the present invention is different From the method according to the patent No. 22,391 the thread, after exiting the second coagulation bath, is wound into a coil in a pre-processing centrifuge. The figure shows an apparatus for carrying out the method according to the invention. The viscose solution is routed in the usual way through the pre-quenching nozzles to the coagulating bath /, whereupon the plastic thread passes over the roller /, rotating with a circumferential speed Vr Then the thread passes between the flexible rollers 2 - 2, turning with the shaft bone V2 Vlf and then goes to the coagulation bath //. In the bath you can contract completely freely; from this bath, the thread on the guide rollers 3 - 3 and the roller 8, rotating with the speed V, <V2, goes to the pre-chamber centrifuge 9. In the figure, number 4 indicates a viscous filter, number 5 indicates viscose, number 6 - thread tight, figure 7 - thread not stretched. PL
