Description
Fremgangsmåte og apparat til krusning av garn. Method and apparatus for curling yarn.
Oppfinnelsen angår en fremgangsmåte The invention relates to a method
til krusning av garn bestående av over-tvinning av en eller flere elementærtråder eller filamenter under oppvarmning, og tilbaketvinning som finner sted ved etterføl-gende avkjøling. for curling of yarn consisting of over-twisting of one or more elementary threads or filaments during heating, and back-twisting that takes place during subsequent cooling.
Oppfinnelsen angår videre et apparat til utførelse av denne fremgangsmåte. The invention further relates to an apparatus for carrying out this method.
Det er kjent å kruse garn av kunstfibre It is known to crimp yarn from artificial fibers
ved å utsette tråder av garnet for sterk turbulens av en fluidumstrøm, slik at enkelte av trådfilamentene i garnet kruser seg. Se f. eks. britisk patent nr. 732.929. by exposing threads of the yarn to strong turbulence of a fluid flow, so that some of the thread filaments in the yarn curl. See e.g. British Patent No. 732,929.
For fremstilling av tekstiler som har For the production of textiles that have
stor elastisitet og har samme utseende som ull, men er fremstilt av garn av kunststof-fer, er det vanlig først å tvinne disse garn sterkt og opphete dem, hvoretter garnet for fiksering av tvinningen påny avkjøles. Der-etter blir garnet tilbaketvunnet slik at garnet kruser seg og er meget elastisk. great elasticity and has the same appearance as wool, but is made from synthetic fiber yarn, it is usual to first twist these yarns strongly and heat them, after which the yarn is cooled again to fix the twist. The yarn is then rewound so that the yarn curls and is very elastic.
Oppfinnerne har funnet at antall tvin-ninger i garnet pr. lengdeenhet må være meget stort for oppnåelse av den ønskete virkning, slik at garnet bare langsomt kan løpe gjennom en tvinnemaskin, eller hvis man vil ha en stor produksjonskapasitet, må antall omdreininger av tvinneorganet være meget stort. En har forsøkt å fremstille tvinnespindler som var istand til å utføre 100.000 omdreininger pr. minutt. The inventors have found that the number of twists in the yarn per length unit must be very large to achieve the desired effect, so that the yarn can only slowly run through a spinning machine, or if you want a large production capacity, the number of revolutions of the spinning device must be very large. An attempt has been made to produce twining spindles that were able to perform 100,000 revolutions per minute. minute.
Naturligvis medfører dette store kon-struksj onsvanskeligheter. Naturally, this entails major construction difficulties.
Oppfinnelsen har til formål å tilveie-bringe en fremgangsmåte og et apparat for tvinning av garn uten at det trenges roterende deler, slik at en med en stor pro-duksjonsevne kan fremstille overtvunnete og tilbaketvunnete garn. The purpose of the invention is to provide a method and an apparatus for twisting yarn without the need for rotating parts, so that one with a high production capacity can produce overtwisted and backwound yarns.
Fremgangsmåten ifølge oppfinnelsen består i at en meddeler et opphetet garn en falsk tvinning, og oppfinnelsen karak-teriseres ved at garnet tvinnes i et hvirvelkammer under påvirkning av en rotasjonsbevegelse av luft på en bukt av garnet i hvirvelkammeret, idet luft eller gass som strømmer inn i hvirvelkammeret samtidig avkjøler det tvunnete garn, mens garnet før det føres inn i hvirvelkammeret passerer en opphetningsinnretning i tvunnet tilstand. The method according to the invention consists in giving a heated yarn a false twist, and the invention is characterized by the yarn being twisted in a vortex chamber under the influence of a rotational movement of air on a bay of the yarn in the vortex chamber, as air or gas flowing into the swirl chamber simultaneously cools the twisted yarn, while the yarn passes through a heating device in the twisted state before being fed into the swirl chamber.
Fikseringen av garnets tvinning mu-liggjøres ved at garnet etter oppvarmning avkjøles av de tangensialt rettete luft- og gasstrømmer som samtidig meddeler en garnsløyfe 1 rotasjon. The fixing of the yarn's twist is made possible by the yarn being cooled after heating by the tangentially directed air and gas flows which at the same time give a yarn loop 1 rotation.
I praksis kan denne fremgangsmåte utføres meget enkelt derved at garnet for å oppvarmes føres gjennom et rørformet oppvarmningselement, hvori garnet under fremmatning meddeles en rotasjon. In practice, this method can be carried out very simply by passing the yarn to be heated through a tubular heating element, in which the yarn is given a rotation during feeding.
Ved enkelte garnsorter anbefales det å føre garnet diskontinuerlig gjennom oppvarmningselementet hvor den tangensialt rettete luft- eller gasstrøm oppretthol-des konstant for å meddele garnet en kon-tinuerlig rotasjon. Denne fremgangsmåte kan lett utføres med et apparat som om-fatter en oppvarmningsinnretning bak hvilken det anordnes et hvirvelkammer med tilførsels- og avløpsåpning. In the case of certain types of yarn, it is recommended to pass the yarn discontinuously through the heating element where the tangentially directed air or gas flow is maintained constantly in order to give the yarn a continuous rotation. This method can easily be carried out with an apparatus which includes a heating device behind which a vortex chamber with supply and drain opening is arranged.
En praktisk utførelse av apparatet oppnås ifølge oppfinnelsen ved at et batteri av opphetningsinnretninger og hvirvelkammere er anordnet slik at et antall tråder kan gjennomføres ved siden av hverandre. A practical embodiment of the apparatus is achieved according to the invention in that a battery of heating devices and vortex chambers are arranged so that a number of threads can be run next to each other.
Noen utførelseseksempler på apparater ifølge oppfinnelsen er illustrert på tegnin-gen. Fig. 1 er et skjema av hvilket anordningen av de enkelte deler av apparatet fremgår. Fig. 2 er en del av et skjema som viser anordningen av kobinerte apparatdeler. Some design examples of devices according to the invention are illustrated in the drawing. Fig. 1 is a diagram showing the arrangement of the individual parts of the apparatus. Fig. 2 is part of a diagram showing the arrangement of combined device parts.
Fra en eller flere garnhesper 1 kom-mer trådene 11 som forenes til en sam-menhengende tråd 12 for å underkastes behandlingen ifølge oppfinnelsen. From one or more yarn loops 1 come the threads 11 which are combined into a continuous thread 12 to be subjected to the treatment according to the invention.
Selvfølgelig er det også mulig å be-handle en enkelt tråd, slik at der i dette til-felles trekkes en tråd av fra en enkelt hespe eller spole, idet filamentene 11 fal-ler bort. Of course, it is also possible to treat a single thread, so that in this case a thread is pulled off from a single hook or coil, the filaments 11 falling away.
For å meddele tråden 12 en ønsket spenning, passerer den en garnbremse 2. Bak denne garnbremse er anordnet et opp-hetningsrør 3. Dette rør kan være forsynt med en hetespiral eller et innvendig hete-medium, f. eks. opphetet luft eller væske. Bak oppvarmningsrøret er anordnet et hvirvelkammer 4 som garnet 12 kan tre inn i gjennom åpningen 6 og forlate gjennom åpningen 7. In order to give the thread 12 a desired tension, it passes a yarn brake 2. Behind this yarn brake is arranged a heating tube 3. This tube can be equipped with a heating coil or an internal heating medium, e.g. heated air or liquid. Behind the heating tube is arranged a vortex chamber 4 into which the yarn 12 can enter through the opening 6 and leave through the opening 7.
I dette kammer befinner der seg en eller flere tangensialt i forhold til garnet anordnete tilførselsåpninger 5 for luft eller gass som tilføres med høy hastighet. Denne luft får i form av en hvirvel en stor rota-sjonshastighet hvorved garnet trekkes ut til en sløyfe som utfører en rotasjon. Ved anvendelse av denne sløyfe eller utbukt-ning som opptrer automatisk i garnet som følge av sentrifugalkraften er rotasjons-retningen ved innløpsåpningen 6 i hvirvelkammeret den samme som ved utløpsåp-ningen, slik at garnet tvinnes i retning av opphetningsrøret. For en god føring av garnet, f. eks. ved tilbaketvinning er der anordnet en garnbremse 8. In this chamber there are one or more supply openings 5 arranged tangentially in relation to the yarn for air or gas which is supplied at high speed. This air, in the form of a vortex, is given a high rotational speed whereby the yarn is pulled out into a loop which performs a rotation. When using this loop or bulge that occurs automatically in the yarn as a result of the centrifugal force, the direction of rotation at the inlet opening 6 in the vortex chamber is the same as at the outlet opening, so that the yarn is twisted in the direction of the heating tube. For good guidance of the yarn, e.g. when rewinding, a yarn brake 8 is provided.
Da der bare tilføres kold gass eller kold luft til hvirvelkammeret som unnviker Then only cold gas or cold air is supplied to the vortex chamber which avoids
gjennom åpningen 6, vil tvinningen som oppstår i opphetningsrøret fikseres. Om nødvendig kan luften også delvis unnvike gjennom åpningen 7. through the opening 6, the twisting that occurs in the heating tube will be fixed. If necessary, the air can also partially escape through the opening 7.
Det tilbaketvunnete garn oppvikles på en rulle 10 som samtidig tjener til gjen-nomtrekning av garnet gjennom apparatet. The rewound yarn is wound on a roller 10 which simultaneously serves to draw the yarn through the apparatus.
Om det er nødvendig å la prosessen foregå diskontinuerlig, blir garnet 12, før det vikles opp på rullen 10, ført gjennom en frem og tilbake bevegelig løkke 9. If it is necessary to allow the process to take place discontinuously, the yarn 12, before being wound up on the roll 10, is passed through a back and forth moving loop 9.
En kombinasjon av hvirvelkammeret med opphetningsrørene er mulig slik som vist på fig. 2. Hvirvelkammerne 4 er her anordnet i et hus som fortrinsvis er utført som en vindkjel. A combination of the vortex chamber with the heating tubes is possible as shown in fig. 2. The vortex chambers 4 are here arranged in a housing which is preferably designed as a wind boiler.
Opphetningsrørene er i fellesskap anordnet i en varmeveksler slik at et stort antall tråder kan tvinnes ved siden av hverandre. Garnbremsene 2 og 8 er fortrinsvis likeledes kombinert, mens rullene 10 har felles aksel. The heating pipes are jointly arranged in a heat exchanger so that a large number of threads can be twisted next to each other. The yarn brakes 2 and 8 are preferably likewise combined, while the rollers 10 have a common axle.
