Description
Ved fremstilling av filtduker, spesielt papirmaskinfilter, har man i mange år festet løse tekstilfiberlag på vevede underlag ved hjelp av såkalt nåling (needling). In the production of felt cloths, especially paper machine filters, loose textile fiber layers have been attached to woven substrates using so-called needling for many years.
Nåling muliggjør fastnålning av f.eks. tykke lobelegg på relativt lette bunnvevnader eller syntetiske fibre med naturfibre i vil-kårlig blanding. Den på denne måte oppnådde lofastgjøring resp. loforankring i bunnvevnaden er imidlertid ofte ikke tilstrekkelig fast for papirmaskinfilter. Sammenviklingen av fibrene innbyrdes, såsom den finner sted ved nålningen, likesom vedheftningsevnen hos fibrene, som gjennomnåles gjennom trådene i bunnvevnaden, Pinning enables pinning of e.g. thick fluff coatings on relatively light bottom fabrics or synthetic fibers with natural fibers in a random mixture. The law enforcement achieved in this way resp. however, loofah anchorage in the bottom tissue is often not sufficiently firm for paper machine filters. The entanglement of the fibers into each other, as it takes place during needling, as well as the adhesion of the fibers, which are needled through the threads of the base fabric,
er i praksis som oftest ikke tilstrekkelig. Ofte løsner loen etter noen løpetid fra bunnvevnaden eller fibertapet blir så stort at filten markerer for tidlig. is in practice usually not sufficient. Often, after some running time, the fluff detaches from the base fabric or the fiber loss becomes so great that the felt marks too early.
Det er riktignok fremkommet forslag for å gjøre forankringen avAdmittedly, proposals have been made to do away with the anchoring
de innålede fibre enda sikrere, f.eks. gjennom innarbeidelse av en bestemt mengde krympefibre i den for pånålning bestemte lo, the needled fibers even more securely, e.g. through the incorporation of a specific amount of shrink fibers in the fluff intended for needling,
som ved opphetning med vanndamp eller ved kokning i vann krymper sterkt og derved fortsetter loen, men denne foranstaltning er imidlertid kostnadskrevende og kan ikke anvendes under alle forhold. which, when heated with steam or when boiled in water, shrinks strongly and thereby the fluff continues, but this measure is, however, costly and cannot be used under all conditions.
Ifølge en annen fremgangsmåte føres undersiden av nålede filter over gassflammer, hvorved en del av de utskytende fibre smelter sammen med hverandre. Denne metode har den ulempe at bare nålede filter med helsyntetisk belegg kan forarbeides, ettersom ull- According to another method, the underside of the needle filter is passed over gas flames, whereby part of the projecting fibers fuse with each other. This method has the disadvantage that only needle-punched filters with a fully synthetic coating can be processed, as wool
eller bomullfibre ødelegges ved den for behandlingen nødvendige temperatur. or cotton fibers are destroyed at the temperature required for the treatment.
Ifølge foreliggende oppfinnelse er det utarbeidet en fremgangsmåte som.ikke lider av de ovenfor nevnte mangler. Ved denne fremgangsmåte oppnås en tilstrekkelig fast forankring av loen i bunnvevnaden, idet fibrene ved hjelp av et elastisk vannuoppløselig klebestoff på filtundersiden forbindes med hverandre ved sine krysnings- og berøringspunkter på en slik måte at vannets gjen-nomgang ikke påvirkes ved filtvask. According to the present invention, a method has been prepared which does not suffer from the above-mentioned shortcomings. With this method, a sufficiently firm anchoring of the fluff in the bottom fabric is achieved, as the fibers are connected to each other at their crossing and contact points by means of an elastic water-insoluble adhesive on the underside of the felt in such a way that the passage of water is not affected when washing the felt.
Fremgangsmåten ifølge oppfinnelsen for fastgjøring av fibrene til filtduker, spesielt papirmaskinfilter, erkarakterisert vedde trekk som er angitt i patentkravet. The method according to the invention for attaching the fibers to felt cloths, especially paper machine filters, is characterized by features which are stated in the patent claim.
Klebestoffet, som er uten vanninnhold og som fremdeles inneholder et organisk oppløsningsmiddel, fordeles på en slik måte i fiberduken, at det etter opphevelsen av presstryk-ket og etter behandlingen med pressluften bare befinner seg på de enkelte fibre og spesielt ved punktene for deres gjensidige berøring, uten at det er trengt gjennom like til oversiden av filtduken. Klebestoffet er fortrinnsvis kunstharpiks-basert. The adhesive, which is water-free and still contains an organic solvent, is distributed in the fiber cloth in such a way that, after the release of the pressing pressure and after the treatment with the compressed air, it is only found on the individual fibers and especially at the points of their mutual contact , without it penetrating right to the top of the felt cloth. The adhesive is preferably synthetic resin-based.
Det er riktignok kjent å forankre fibrenes krys-ningspunkter i en papirmaskinfilt ved hjelp av slike herdbare klebestoffer. Det har imidlertid ikke vært mulig å oppnå en tilstrekkelig sikker forbindelse uten begrensning av gjennom-strømningsåpningene ved hjelp av kjente fremstillingsmåter. It is admittedly known to anchor the crossing points of the fibers in a paper machine felt by means of such hardenable adhesives. However, it has not been possible to achieve a sufficiently secure connection without limiting the through-flow openings by means of known production methods.
Påføringen av klebestoffet på undersiden av filtduken kan skje ved hjelp av sprøytedyser, ved hjelp av en sjaber eller ved hjelp av med klebestoff forsynte valser. Den mekaniske sammenpressing av filtduken kan gjennomføres på en hvilken som helst egnet måte, f.eks. gjennom to i motsatt ret-ning roterende valser. The application of the adhesive on the underside of the felt cloth can be done with the help of spray nozzles, with the help of a scraper or with the help of rollers supplied with adhesive. The mechanical compression of the felt cloth can be carried out in any suitable way, e.g. through two rollers rotating in opposite directions.
For å oppnå en påskyndet herdning av den med klebestoff forsynte filtduk, anvender man hensiktsmessig pressluft med lett forhøyet temperatur. In order to achieve an accelerated hardening of the felt cloth provided with adhesive, suitable compressed air with a slightly elevated temperature is used.
Etter pressluftbehandlingen underkastes filtduken på ny et presstrykk, f.eks. ved hjelp av to valser, for at de med klebestoffet overtrukne fibre skal sammenklebes ved ytterligere berøringssteder. After the compressed air treatment, the felt cloth is again subjected to a pressure, e.g. with the help of two rollers, so that the fibers coated with the adhesive are glued together at further points of contact.
En nålet papirmaskinfilt føres gjennom to roterende metallvalser, på den undre av hvilke det ved hjelp av en av-stryker er påført et ensartet tykt sjikt av et vannuoppløselig elastisk klebestoff, f.eks. butadien-akrylnitril eller 2-klor-butadien. Når valsene presser filten sammen, trenger klebestoffet inn i fibersjiktene og omhyller fibrene. Når filten så har forlatt valsene, går fibrene raskt tilbake til sin opprinnelige voluminøse tilstand. Ved hjelp av kraftige pressluftstråler rives de klebestoffhinner som fremdeles befinner seg mellom de mange fibre istykker, så at klebestoffet i hovedsaken forleg-ges til berørings- og krysningspunktene for fibrene. A needle-punched paper machine felt is passed through two rotating metal rollers, on the lower of which a uniformly thick layer of a water-insoluble elastic adhesive, e.g. butadiene-acrylonitrile or 2-chloro-butadiene. When the rollers press the felt together, the adhesive penetrates the fiber layers and envelops the fibers. Once the felt has left the rollers, the fibers quickly return to their original voluminous state. With the help of powerful compressed air jets, the adhesive material membranes that are still between the many fibers are torn to pieces, so that the adhesive material is mainly located at the points of contact and crossing of the fibers.
Den på denne måte behandlede filt blir innen klebestoffet har herdnet, av to roterende valser presset så sterkt sammen, at de med klebestoff overtrukne fibre kommer i berøring med hverandre på ytterligere steder og også der sammenklebes med hverandre. The felt treated in this way, before the adhesive has hardened, is pressed together by two rotating rollers so strongly that the fibers coated with adhesive come into contact with each other in further places and are also stuck together there.
Papirmaskinfilter, hvis fibre festes på underlaget i henhold til denne fremgangsmåte, oppviste i drift knapt noe fibertap. Dessuten var deres løpeegenskaper på papirmaskinen god. En gang innstilte filter behøvde praktisk talt ikke lenger å etterreguleres. Dette beror for en stor del på den gode ved-heftningen av det elastiske bindemiddel på overflaten av valsene . Paper machine filters, whose fibers are attached to the substrate according to this method, showed hardly any fiber loss in operation. Moreover, their running characteristics on the paper machine were good. Filters once set practically no longer needed to be readjusted. This is largely due to the good adhesion of the elastic binder to the surface of the rollers.
Også ikke-nålede papirmaskinfilter, hvis underside ble behandlet i samsvar med denne fremgangsmåte, viste seg be-tydelig bedre enn vanlige filter med hensyn til stabilitet, løpeegenskaper og fibervedheftning. Also non-needle paper machine filters, the underside of which was treated in accordance with this method, proved significantly better than ordinary filters with regard to stability, running properties and fiber adhesion.
