Description
Foreliggende oppfinnelse vedrører en fremgangsmåte ved fremstilling av celluloseformlegemer fra en oppløsning av cellulose i N-metylmorfolin-N-oksyd (NMMO) og vann, hvor oppløsningen formes og cellulosen derefter felles ut i et utfellingsbad som inneholder vann og NMMO.
Fra f. eks. US-PS 4 196 282 er det kjent å fremstille en oppløsning av cellulose i N-metylmorf olin-N-oksyd (i det følgende forkortet til NMMO) og vann. Celluloseopp-løsninger er nødvendige f.eks. ved fremstilling av cellu-losef ibre eller andre formlegemer på cellulosebasis. Til dette formål ekstruderes oppløsningen gjennom spinnedyser i et utfellingsbad. Anvendelsen av en blanding av NMMO og vann som oppløsningsmiddel har forskjellige fordeler; fremfor alt skal det fremheves at et (nærmest) lukket oppløsnigsmiddelkretsløp er mulig slik at miljøbelastningen kan holdes meget lavt.
Under NMMO-prosessen blir cellulosen som er oppløst i NMMO og vann, koagulert i et NMMO-holdig utfellingsbad. Fibrene blir derefter vasket, vaskevannet blir ført tilbake til utfellingsbadet og utfellingsbadet blir inndampet. Destillatet anvendes til vaskning av fibrene (som ovenfor), og NMMO-konsentratet anvendes pånytt ved en ny oppløsnings-fremstilling.
I utfellingsbadet har NMMO-konsentrasjonen hittil vært begrenset til ca. 20% til 25%, fordi høyere konsentrasjoner påvirket de tekstilmekaniske egenskaper i fibrene. Det ville imidlertid være ønskelig å kunne heve NMMO-konsentrasjonen i utfellingsbadet, for derefter å måtte fordampe mindre vann fra utfellingsbadet.
Oppgaven for foreliggende oppfinnelse består således i å utforme fremgangsmåten av den innledningsvis nevnte art slik at man også ved høye NMMO-konsentrasjoner i ut f ellingsbadet oppnår gode fiberegenskaper.
Denne oppgave løses ifølge oppfinnelsen, som angitt i kravet, ved at temperaturen i utfellingsbadet er høyst 0°C.
Det ble nemlig overraskende funnet at man kan anvende NMMO-konsent ras joner på over 40 % i utf ellingsbadet, når man senker utfellingsbadtemperaturen til under 0°C.
For å underbygge de ovenfor angitte påstander skal oppfinnelsen sammenlignes med teknikkens stand ved hjelp av følgende eksempler:
Eksempel 1 til 6:
2276 g cellulose (faststoff- eller tørrinnhold 94%, DP 750 [DP = gjennomsnittspolymerisasjonsgrad] , alpha = 98%) og 0,02% gallussyrepropylester suspenderes i 26139 g 60% vandig N-metylmorfolin-N-oksyd-oppløsning; derefter av-destilleres 4915 g vann i 2 timer ved 100°C og et vakuum på50til 300 mbar. Den derved dannede spinneoppløsning hadde følgende sammensetning: cellulose: 10%, vann: 12%, NMMO: 78%. Den ble presset gjennom en dyse med 589 hull (hull-diameter 130/xm) . Spinnetemperatur var da på 75°C. De dannede fibre ble - efter strekking i en luftspalte - felt ut i et NMMO-holdig utfellingsbad. Titeren, NMMO-konsentrasjonen i utfellingsbadet, og temperaturen i utfellingsbadet er for de enkelte eksempler angitt i tabell 1; av denne tabell fremgår de respektive dannede fiberegenskaper. Her betyr:
FFk fiberfasthet (kondisjonert)
FDk fiberuttøyning (kondisjonert)
SF slyngefasthet
Eksempel 1 og 2 tilsvarer teknikkens stand; i utfellingsbadet anvendes det rent vann (eksempel 1) hhv. vann med ca. 20% NMMO (eksempel 2); utfellingsbadtemperaturene er relativt høye (15 hhv. 11°C) . De i disse utf ellingsbad utfelte cellulosefibre har tilfredsstillende egenskaper. I eksempel 3 ble det forsøkt å øke NMMO-konsentrasjonen i utfellingsbadet til 40%; herved blir imidlertid fiberegenskapene tydelig dårligere.
Eksempel 4 til 6 er eksempler ifølge oppfinnelsen, dvs. temperaturene var på høyst 0°C. Som man kan se, påvirker en økning av NMMO-konsentrasjonen i utfellingsbadet ved disse temperaturer fiberegenskapene vesentlig mindre; således er f.eks. fibrene ifølge eksempel 5 absolutt likeverdig xnéL fibrene ifølge eksempel 1.
