Description
Oppfinnelsen gjelder en fremgangsmåte av den art
som er beskrevet i innledningen til patentkrav 1.
Det er kjent å fremstille såkalte syntetiske filter, hvor fiberflor av forskjellige fiberslag sammennåles med hverandre, hvoretter det således dannede fibersjikt i sammenfest-ningsøyemed underkastes en krympningsprosess.
Det er videre kjent å forbinde fibrene av på karde-maskiner eller aerodynamisk fremstilte fiberflor ved hjelp av latex, påsprøytede klisterdråper, fukting av overflatene med oppløsningsmiddel, smeltefibre eller klebestofftråder med hverandre .
Ifølge en annen fremgangsmåte underkastes et nålet fibersjikt en krympningsbehandling, innsettes i tilslutning hertil med en bindemiddeloppløsning, behandles med vann før av-dunstningen av oppløsningsmidlet og tørkes deretter.
Ifølge denne og lignende metoder fremstilte ikke vevede produkter anvendes innen tekstilindustrien eller videre-forarbeides f.eks. til kunstlær gjennom påføring av et plast-sjikt. Forsøk på å fremstille f.eks. papirmaskinfilter av dis-se produkter_har hittil vært resultatløse, ettersom de ikke vevede produkter bare har en ganske liten slitestyrke og dessuten altfor stor tøybarhet.
Ved papirmaskinfilter har bunnvevnaden til oppgave
å bære loen og dessuten å gi filten formstabilitet og fasthet fremfor ålt overfor strekkpåkjenning. I mange henseender er bunnvevnaden imidlertid forstyrrende, f.eks. når filter, som fremstilles som endelig stykke, må sammenføyes til en endeløs bane. Da krever inntrekkingen av hver enkelt bunnvevnadstråd på den ene filtdukende inn i den rett ovenfor liggende ende, meget tid.
Også i andre henseender utgjør bunnvevnaden et kom- promiss. For ved papirfremstillingen å motstå den opptredende strekkpåkjenning må renningstrådené være tilstrekkelig sterke. Den på bunnvevnaden påførte lo må i det minste være så tykk at bunnvevnaden ikke gjennomtrykkes og lager merker på papirbanen.
Man har derfor lenge søkt etter et bunnmateriale, som ikke hadde noen ufordelaktige egenskaper. Således anvendes ifølge en nyere fremgangsmåte istedenfor en bunnvevnad et stort antall parallelle tråder, hvorpå nåles et fiberflor.
Fra tysk patentskrift 582.911 er det kjent å beleg-ge filt med fiberbindingsmiddel, nærmere bestemt gummiløsning, ved nedsenkning i slik løsning. Denne fremgangsmåte vil imidlertid redusere filtens åpninger eller porøsitet i uønsket grad.
I norsk patentskrift 45.222 er det beskrevet en ned-dykking av en løs papirstruktur i en latex e.l. for å frembrin-ge et papirliknende produkt med "tøy-kvalitet". Denne fremgangsmåte er imidlertid ikke egnet for fremstilling av filt for papirmaskiner.
Fra britisk patentskrift 654.079 er det kjent en fremgangsmåte for fremstilling av filt for papirmaskiner, hvor filtbaner med klebestoff påført føres over valser samtidig som det blåses luft over filtbanen fori å tørke klebestoffet. Denne fremgangsmåte alene har imidlertid, ikke vært tilstrekkelig for å skape en tilfredsstillende papirmaskinfilt.
Endelig er det kjent fra USA-patentskrift 2.910.763 å fremstille et filtliknende produkt ved å legge flere lag fiberflor i kryss. Her benyttes det imidlertid intet fiberbindingsmiddel som kan gjøre en slik fremstilt filt egnet for bruk i papirmaskiner.
Hensikten med den foreliggende oppfinnelse er å skaffe en fremgangsmåte ved hvilken de omtalte ulemper avhjelpes.
Det har vist seg at man kan fremstille en tilstrekkelig fast og målstabil filt uten bunnvevnad eller forsterkende eller stabiliserende innlegg ved å benytte den fremgangsmåte " * • som er beskrevet i patentkravet.
Særskilt egnet herfor er florsjikt med en flatevekt på fra 20 til 150 g/m . Banen av. flere fiberflorsjikt naies fra den ene eller begge sider ved hjelp av en nålemaskin. Den anvendte nåltype, fremskyvningen, innstikningsdybden for nålene og antall innstikninger pr. cm 2 er avhengig av fibertykkelsen, florsjikttykkelsen og de ønskede egenskaper hos den ferdige, nålede filt.
Etter nålingen av den endeløse fiberbane strekkes denne alt etter fiberslaget meget kraftig, for å bringe en stor del av de i hverandre innviklede fibre i en spent tilstand. For ytterligere fastgjøring forbindes filtfibrene ved hjelp av et vannuoppløselig elastisk klebestoff på den ene eller begge sider, f.eks. butadinakrylnitril eller 2-klor-butadien, eventuelt således med hverandre at vann fremdeles kan trenge uhindret gjennom filten.
For påføring av klebestoffet er hittil kjente metoder uegnede. Enten trenger klebestoffet ikke tilstrekkelig dypt inn i filten, f.eks. når det påføres ved hjelp av sprøytedyser, eller det oppsuges ukontrollert dypt i filten, f.eks. ved ned-dyppings- eller inntrekkingsmetoder. Derfor må den ifølge foreliggende oppfinnelse fremstilte filt, såfremt den skal anvendes som papirmaskinfilt bare forsynes fra den ene side med et ensartet tykt sjikt av et vannuoppløselig elastisk klebestoff, der-på sammenpresses og i tilslutning hertil på den med klebestoff forsynte side behandles med en kraftig pressluftstråle. Herved fordeles klebestoffet, som fremdeles inneholder organisk opp-løsningsmiddel, under istykkerriving av den eventuelt dannede klebestoffhinne på en slik måte i filten at klebestoffet, etter opphevelsen av presstrykket og etter behandlingen med pressluft, bare befinner seg på de enkelte fibre og spesielt ved deres gjensidige berøringspunkter. v
Påføringen av klebestoffet f.eks. på papirmaskinfil-ten kan skje på vilkårlig måte f.eks. ved hjelp av sprøytedyser, ved hjelp av en avstryker, sjaber eller ved hjelp av med klebestoff forsynte valser. Den mekaniske sammenpresning av filten kan likeledes gjennomføres på ønsket måte, f.eks. ved hjelp av to i motsatt retning roterende valser.
For å oppnå en påskyndet tørkning av den med klebestoff forsynte filt, kan man den anvendte pressluft ha litt for-høyet temperatur.
Etter pressluftbehandlingen kan filten, innen klebestoffet har tørket, enda en gang underkastes et presstrykk, f.eks. ved hjelp av to valser, for at de med klebestoff over trukne fibre skal sammenklebes på ytterligere berøringssteder.
Eksempelvis sammenpresses de nålede flor ved hjelp
av to roterende metallvalser, hvorav den under ved hjelp av en avstryker er påført et ensartet tykt klebestoffsjikt, hvorved klebemidlet trenger inn i de under fibersjikt og omhyller fib-
rene. Når filten har forlatt valsene, går fibrene raskt til-
bake til sin opprinnelige voluminøse tilstand. Ved hjelp av kraftige pressluftstråler slites de fremdeles mellom fibrene værende klebestoffhinner istykker, så at klebestoffet hovedsa-
kelig forlegges til berørings- og krysningspunktene for fibrene.
Etter å ha forlatt påføringsvalsene kan filten, in-
nen klebestoffet har tørket, enda en gang sammenpresses gjen-
nom to valser så kraftig, at de med klebestoff overtrukne fib-
i
re berører hverandre ved ytterligere steder og også der sammenklebes med hverandre.
På denne måte fremstilte våtfilter er vesentlig slitesterkere enn de tradisjonelle våtfilter med samme flate-
vekt og utsettes under sin innsetning i f.eks. papirmaskinen praktisk talt ikke for noe fibertap. En markering er herved utelukket da bunnvevnaden mangler. Slike filter har mange gan-
ger større total løpetid enn tradisjonelle papirmaskinfilter.
På mange anvendelsesbmråder innen papirtilvirkning-
en har det vist seg formålstjenlig å blande naturlige og synte-
tiske fibre for å kombinere denne fiberslags gode egenskaper.
For eksempel kan fiberflor av forskjellige fiberslag legges
over hverandre, eller det kan anvendes fiberflor av fiberblan-dinger. I førstnevnte tilfelle er det hensiktsmessig å oriente-
re fiberflor med tykkere fibre i retningen for strekkpåkjen-
ningen.
Claims (1)
- Fremgangsmåte for fremstilling av nålede filter for papir- og lignende maskiner, bestående av en bane av to eller flere fiberflor hvert med vesentlig parallelle, i florets plan orienterte fibre, eventuelt av forskjellige slag, i det- fibrene fra florsjikt til florsjikt danner en vinkel med hverandre og er belagt med fiberbindingsmiddél, karakterisert ved at banen, etter på kjent måte å være nålet fra den ene eller begge sider og strukket, påføres fiberbindingsmiddeletpå den ene side og som i og for seg kjent presses for å fordele fiberbindingsmiddelet i florene, hvoretter fiberbanen tillates å ekspandere, og på kjent måte, for å åpne banen og tørke fiberbindingsmiddelet , gjennomblåses fra klebemiddelsiden med skar-pe, fortrinnsvis varme pressluftstråler hvoretter banen før full inntørking av fiberbindingsmiddelet presses enda en gang for å forbinde fibrene i kryssingspunktene.
