Description

Apparat for trekking av fine glassfibre. Apparatus for drawing fine glass fibres.

Foreliggende .oppfinnelse angår ,et apparat! for trekking av fine kontinuerlige fibre fremstilt av i varme mykbart mineralskt materiale og omfatter en utmatningsanordning for strøm-mer av glassmateriale, hvilken utmatningsanordning er anordnet til å inneholde e,t forråd av det ved hjelp av varme flytendegjorte mate-! riale og hvilken utmatningsanordning er for-' synt med en bunn med et antall nedoverrettede stusser med lik lengde. The present invention relates to an apparatus! for drawing fine continuous fibers produced from heat-softening mineral material and comprising a discharge device for streams of glass material, which discharge device is arranged to contain a supply of the feed liquefied by heat. rial and which dispensing device is provided with a bottom with a number of downwardly directed stubs of equal length.

Tråder av kontinuerlige glassfibre er fremstilt kommersielt og brukes til fremstilling av tøyer, som har den fordelen at de er meget sterke og stabile. Kommersiell tråd av kontinuerlige fibre har hittil hatt en midlere fiber-finhet over 0,0050 mm. Til tross for at disse fibre er meget sterke, har det vist seg ønskelig med større smidighet ved finere fibre i fine stoffer, særskilt da disse stoffer skal være såkalt krøllfrie. Threads of continuous glass fibers are produced commercially and are used in the manufacture of fabrics, which have the advantage of being very strong and stable. Commercial thread of continuous fibers has so far had an average fiber fineness above 0.0050 mm. Despite the fact that these fibers are very strong, it has been shown to be desirable to have greater flexibility with finer fibers in fine fabrics, especially as these fabrics must be so-called wrinkle-free.

.Stoffer som er fremstilt ay glassfiber garn, har selv om de forøyrig har vist seg å være meget holdbare dårlig elitestyrke og smidighet. Det ;har yist seg at man ved .å øke finheten vesent-lig på .de kontinuerlige fibrene i .trådene .som .stoffene er vevet eller på annen måte fremspilt, .oppnår man stoffer med meget s.tørre holdfast-;het pg bedre .krølleegenskaper, smidighet .og sli-testyrke enn tidligere stoffer. De har også meget bedre fall og er mykere og oppnår et «kost-barere utseende», samtidig med større slitestyr-ke og dermed meget større levetid. .Fabrics made from glass fiber yarn, although they have proven to be very durable, have poor elite strength and flexibility. It has been found that by significantly increasing the fineness of the continuous fibers in the threads with which the fabrics are woven or produced in some other way, fabrics with a very dry hold fastness are obtained due to better .creasing properties, suppleness .and wear resistance than previous fabrics. They also have a much better fall and are softer and achieve a "cheaper appearance", at the same time with greater wear resistance and thus a much longer lifespan.

Det er tidligere blitt kommersielt produsert kordeler eller garn av kontinuerlige glassfibre, men fibrene har ikke vært fine nok for effektivt å motstå opprulling og ikke fine nok til å sikre en god bøyelighet eller foldekarakteristikk i garnet. Videre er det konstatert at strekkstyr-ken på garn av kontinuerlige glassfibre og tek-stiler vevet av slike øker ved bruk av finere fibre av glass. Meget fine fibre av glass kan fremstilles i laboratorier, men en slik fremgangsmåte kan ikke brukes ved kommersiell fremstilling på grunn av alt for høye omkost-ninger. Ved produksjon av garn av meget fine kontinuerlige fibre er det viktig å øke antallet fibre i hver kordel eller garn i forhold til det som har vært tilfelle før. En økning av antallet fibre i en tråd nødvendiggjør et tilsvarende antall utløpsåpninger på matean-ordningen for å oppnå det nødvendige antall glass-strømmer for forming av fibre. I indu-striell fremstilling-må alle strømmene av kontinuerlige fibre til en tråd flyte fra en enkel utmatningsanordning og dette nødvendiggjør en meget tett plassering av utløpsåpningene. Når de har vært plassert så tett inntil hverandre har de tidligere konstruksjoner av dyser hatt en tendens til å forårsake at glasset fløt på tvers av utløpene langs bunnen av utmatningsanordnin-gen. Cord parts or yarns of continuous glass fibers have previously been commercially produced, but the fibers have not been fine enough to effectively resist coiling and not fine enough to ensure good flexibility or folding characteristics in the yarn. Furthermore, it has been established that the tensile strength of yarns of continuous glass fibers and textile styles woven from such increases when finer glass fibers are used. Very fine fibers of glass can be produced in laboratories, but such a method cannot be used in commercial production due to far too high costs. When producing yarn from very fine continuous fibres, it is important to increase the number of fibers in each cord or yarn compared to what has been the case before. An increase in the number of fibers in a thread necessitates a corresponding number of outlet openings on the matean arrangement to achieve the required number of glass flows for forming fibers. In industrial production, all the streams of continuous fibers for a thread must flow from a simple discharge device and this necessitates a very tight placement of the outlet openings. When placed so closely together, the prior designs of nozzles have tended to cause the glass to flow across the outlets along the bottom of the dispenser.

Ifølge nærværende oppfinnelse oppnås en kontinuerlig og kommersielt forsvarlig trekking av fine glassfibre ved et apparat som er karakterisert ved at stussens ytre ringformede, endeflaters ytre diameter ikke er mer enn 0,508 mm større enn den samme flatens indre diameter og at stussen har en maksimal ytre diameter på 1,778 mm. Videre har stussen en så stor innbyrdes avstand at dråper av det mykgjorte materiale som henger ned fra stussene ligger nær hverandre, men ikke berører hverandre slik at sammenflyting forhindres. Hver av stussenes ringformede endeflater har en indre diameter som ikke overstiger 1,524 mm i innven-dig diameter, og en ytre diameter som ikke overstiger 1,778 mm. According to the present invention, a continuous and commercially sound drawing of fine glass fibers is achieved by an apparatus which is characterized in that the outer diameter of the outer ring-shaped, end surfaces of the spigot is not more than 0.508 mm greater than the inner diameter of the same surface and that the spigot has a maximum outer diameter of 1.778 mm. Furthermore, the spigots have such a large mutual distance that drops of the softened material hanging down from the spigots lie close to each other, but do not touch each other so that coalescence is prevented. Each of the spigots' annular end faces has an inner diameter that does not exceed 1.524 mm in inner diameter, and an outer diameter that does not exceed 1.778 mm.

Glasset ledes nedover i hovedsaken jevnt gjennom en mater til et munnstykke eller an-ordning av fine utmatningshull, slik at glas-sets «kanellering» eller tendens til å spre seg gjennom nærbeliggende skikt i hovedsaken eli-mineres. Videre forholder det seg slik at sam-menflytningen som forårsakes av et uheldig utformet matningsmunnstykke og fine hull, vil overvinnes i foreliggende tilfelle ved at materens munnstykkespiss avpasses slik at dråpedannel-sestid og dråpefalltid minskes til et minimum og dråpens tverrmål minskes, slik at mange munn-stykker kan plasseres tett inntil hverandre med minimal tendens til sammenflytning. Derved blir det mulig å, dra et forholdsvis stort antall yt-terst fine fibre, som samles til en tråd, og samtidig minske tendensen til fiberbrudd, hvorved opprettholdes en kontinuerlig trekning. The glass is led downwards in the main body evenly through a feeder to a nozzle or an arrangement of fine discharge holes, so that the glass set's "fluting" or tendency to spread through nearby layers in the main body is eliminated. Furthermore, it is such that the flow caused by an unluckily designed feeding nozzle and fine holes will be overcome in the present case by adjusting the nozzle tip of the feeder so that the droplet formation time and droplet fall time are reduced to a minimum and the transverse dimension of the droplet is reduced, so that many mouths -pieces can be placed close to each other with minimal tendency to flow together. Thereby, it becomes possible to draw a relatively large number of extremely fine fibres, which are collected into a thread, and at the same time reduce the tendency to fiber breakage, whereby a continuous drawing is maintained.

Oppfinnelsen angår en fremgangsmåte til å fremstille fine kontinuerlige fibre av i varme- The invention relates to a method for producing fine continuous fibers from heat-

myket mineralskt materiale, som er finere enn 0,0045 mm, ifølge hvilket et forråd av det gjennom varme mykede materiale holdes flytbart i en mater og strømmer av materialet ledes inn gjennom fine hull i materen og gjennom en trang sone i disse til en utside av hvert av de fine hull hvilken ligger i det vesentlige vinkel-rett mot materialets gjennomstrømningsretning, for å oppnå at en dråpe av det ved varme mykede materiale raskt dannes ved hullet, og dråpens falltids forkortes derved, hvoretter fibrene som trekkes ut av de fallende dråpene samles til en tråd, hvilken tråd spoles på et oppsamlings-organ. softened mineral material, which is finer than 0.0045 mm, according to which a supply of the heat-softened material is kept flowable in a feeder and streams of the material are directed into fine holes in the feeder and through a narrow zone therein to an outside of each of the fine holes which is essentially perpendicular to the flow direction of the material, in order to achieve that a drop of the material softened by heat is quickly formed at the hole, and the drop's falling time is thereby shortened, after which the fibers extracted from the falling drops are collected to a thread, which thread is wound on a collecting means.

En videre hensikt med oppfinnelsen er å til-veiebringe et apparat for å danne de fine kontinuerlige fibrene av det ved varme mykede mineralske materiale, hvilket apparat omfatter en mater som er innrettet til å inneholde et forråd av det gjennom varme materiale i flytbar tilstand, og er forsynt med en bunn utformet med et flertall like lange, nedoverrettede tap-per som inneholder hver sin trange kanal som slutter i et utløp, hvis diameter er maksimum 1,524 mm. A further purpose of the invention is to provide an apparatus for forming the fine continuous fibers of the mineral material softened by heat, which apparatus comprises a feeder which is arranged to contain a supply of the through heat material in a flowable state, and is provided with a bottom formed with a plurality of equally long, downwardly directed pins each containing a narrow channel terminating in an outlet, the diameter of which is a maximum of 1.524 mm.
