Menetelma lankojen ilmateksturointia vårtenMethod for air texturing of yarns
KeksinnOn kohteena on menetelma lasikuidusta muo-dostettujen monisSikeisten lankojen ilmateksturointia var-5 ten, jolloin langat syOtetaan ensimmaiselle syOtinlait-teelle, siita teksturointisuuttimeen ja lopuksi toiselle syOtinlaitteelle.The invention relates to a method for the air texturing of multifilament yarns formed of glass fiber, in which the yarns are fed to a first feeding device, then to a texturing nozzle and finally to a second feeding device.
On jo tunnettua syOttaa lankoja, esimerkiksi myOs lasikuitulankoja, ilman kierteita ensimmåisen syOtinlait-10 teen kautta teksturointisuuttimeen ja siita toiselle syOtinlaitteelle. Tassa menettelyssa voidaan peiata yksit-taisten saikeiden katkeamisia teksturointisuuttimen tulo-aukolla, jotka saattavat aiheuttaa saikeiden kasaantumisia ja lopulta koko langan katkeamisen. Tailaiset yksitellen 15 syOtetyt, kertaamattomat langat aiheuttavat teksturointi-suuttimessa kontrolloimattoman ja epatasaisen pOyhOttymi-sen. Talla tavoin aikaansaatu teksturoitu lanka ei siten ole montaakaan sovellusta vårten tyydyttava.It is already known to feed yarns, for example also fiberglass yarns, without threads through the first feeder-10 to the texturing nozzle and from there to the second feeder. In this procedure, breaks in individual strands can be masked by the inlet of the texturing nozzle, which can cause the strands to accumulate and eventually break the entire yarn. Single, single, non-repetitive yarns cause uncontrolled and uneven flattening in the texturing nozzle. The textured yarn thus obtained is thus unsatisfactory for many applications.
Edelleen on jo tunnettua koota kehruukeloilta tule-20 vat langat ja varustaa ne kierteilia. Talla tavoin synny-tetty materiaali voidaan sitten syOttaa teksturointisuuttimeen. Kertaamisen johdosta mahdollisesti ulostyOntyneet murtuneet saikeet sitoutuvat mukaan lankaan. Tama sitou-tuminen estaa katkenneiden saikeiden kasaantumisen tekstu-25 rointisuuttimen tuloaukolla. Lisaksi tasta materiaalista syntyy tasaisesti pOyhOttynyt teksturoitu lanka.Furthermore, it is already known to assemble the yarns from the spinning spools and equip them with threads. The material thus generated can then be fed to a texturing nozzle. As a result of the repetition, any broken protrusions that protrude will stick to the wire. This binding prevents the accumulation of broken strands at the inlet of the text nozzle. In addition, this material produces a uniformly flattened textured yarn.
Haitallista tassa menetelmassa tosin on, etta ker-taaminen on huomattavan kallista erillisena tyOvaiheena ennen teksturointisuuttimeen syOttOa. Haitallista on li-: ' 30 saksi, etta kertaaminen vaatii hauraamman materiaalin koh- dalla apuvålineiden kayttoa. Niinpa on esimerkiksi tunnet-' tua suorittaa lasikuitumateriaalin kohdalla ns. tekstiili- liistauksia, jotta taman materiaalin kertaaminen ylipaa-taan olisi mahdollista. Taman menetelman haittana on pait-35 si ylimaaraiset kustannukset, myOs se, etta kaytetty teks- 2 90357 tiililiistaus on lankaa myOhemmin kaytettaessa haitaksi siten, etta se esimerkiksi vaikeuttaa langan upottamista matriisiin.However, the disadvantage of this method is that iteration is considerably expensive as a separate work step before feeding to the texturing nozzle. It is detrimental to the use of aids for more brittle material. Thus, for example, it is known to perform in the case of a glass fiber material the so-called textile strips to make it possible to repeat this material at all. The disadvantage of this method is not only the extra cost, but also the fact that the textile brick stripping used is a disadvantage when the yarn is used later, so that it makes it more difficult, for example, to immerse the yarn in the matrix.
Taman keksinnOn tehtavana on aikaansaada edelia 5 mainitun tyyppinen menetelma, jonka avulla teksturoitavat langat voidaan syOttaa teksturointisuuttimeen huomattavas-ti pienemmin kustannuksin ja teksturoida ne siina tasai-sesti. TéllOin langat kuormittuvat vain hiukan, joten edes kriittisten lahtOmateriaalien kohdalla ei juuri tarvitse 10 turvautua apuvaiineisiin.The object of the present invention is to provide a method of the type mentioned above, by means of which the yarns to be textured can be fed to the texturing nozzle at a considerably lower cost and textured therein uniformly. TéllOin yarns are only slightly loaded, so even with critical materials, there is little need to use auxiliary pressures.
Asetettu tehtavS ratkaistaan edelia mainitun tyyp-pisen menetelman kohdalla keksinnOn mukaisesti siten, etta langat syOtetaan ensinunaiselle sydtinlaitteelle erikseen tai kerrattuina ja etta ne teksturointisuuttimen ja toisen 15 syOntilaitteen vaiissa viedaan valekiertimelle, joka tekee lankoihin ensimmaisen syOtinlaitteen ja valekiertimen va-liselia alueella kierteen, joka sitoo kaikki syOtetyt langat yhdeksi kokonaisuudeksi (langaksi). Keksinnttn mukaisen menetelman suositeltavat suoritusmuodot on esitetty oheis-20 tetuissa patenttivaatimuksissa 2-6.The above task is solved in the above-mentioned method according to the invention by feeding the yarns to the first core device separately or in plies and by passing them to a false winder in the silence of the texturing nozzle and the second INSERTED YARNS INTO ONE ENTRY (YARN). Preferred embodiments of the method according to the invention are set out in the appended claims 2-6.
Valmisteleva tydstO, esimerkiksi kertaaminen, ei ole tarpeen ennen ensimmaiselle syOtinlaitteelle tapahtu-vaa syttttoa. Valekierteen tekemisen ja sita seuraavan lan-kojen sulautumisen ansiosta yhdeksi kokonaisuudeksi saa-25 daan mahdolliset lankojen katkokset sidottua, jolloin suuttimen tuloaukolla ei paase syntymaan kasautumia ja saikeiden irtoamista. Taten teksturointisuuttimeen tuleva yksittaisten lankojen muodostama kokonaisuus aikaansaa langan pOyhdttymisen tasaisesti.A preparatory test, for example a repetition, is not necessary before ignition on the first feeder. Thanks to the making of a false thread and the subsequent merging of the yarns, any breaks in the yarns can be tied together, so that no accumulations and loosening of the strands occur at the inlet of the nozzle. The ensemble of individual yarns entering the Tate texturing nozzle causes the yarn to settle evenly.
30 Sen ansiosta, etta langat teksturointisuuttimen ia- paistyaan viedaan valekiertimelle, saavat langat ensimmaisen syOtinlaitteen ja valekiertimen vaiiselia alueella kierteen, joka sitoo kaikki syOtetyt langat yhdeksi kokonaisuudeksi, joka sulkee sisaansa mahdolliset yksittaiset 35 saikeiden katkokset. Siten taiia tavoin kerratun langan 3 90357 oikea kulku on varmistettu. Taiia tavoin muodostettu yk-sikkO altistuu myiJs teksturointisuuttimessa kokonaisuutena sisaan puhalletulle ilmalle. Tasta on seurauksena, etta ilma ei takerru sinansa yksittaisiin lankoihin, vaan lan-5 kojen muodostamaan kokonalsuuteen. Tuloksena on tamMn lan-gan tasalnen pOyhttttyminen. Tata etua ei siis saavuteta erillisten langanpuolaus- ja uudelleenpuolausprosessien kautta, vaan yksinomaan minka tahansa tunnetun rakenteen kasittavan valekiertimen sijoittamisen avulla lankavir-10 taan.Due to the fact that the yarns are introduced into the pseudo winder after the texturing nozzle has passed, the yarns in the silent region of the first feeder and the pseudo-winder have a thread that binds all the fed yarns into one whole, enclosing possible individual thread breaks. Thus, the correct passage of the wire 3 90357 twisted in this way is ensured. The unit formed in this way is also exposed to the blown air as a whole in the texturing nozzle. As a result, the air does not stick to the individual wires of the sinus, but to the whole formed by the lan-5 devices. The result is the unification of the lan-gan flatness. Thus, this advantage is not achieved through separate wire winding and rewinding processes, but solely by placing a false winder that handles any known structure into the wire stream.
KeksinnOn mukainen menetelma voi lisaksi olla suun-niteltu siten, ettå langalle annetaan teksturointisuutti-men alueella aina 150 T/m saakka ulottuva kierre. Monissa tapauksissa on edullista tehda lankaan teksturointisuutti-15 men alueella alle 100 T/m kierre. Tama kierteitys takaa toivotut edulliset vaikutukset syOtettaessa lankoja teks-turointisuuttimeen seka itse puhallustapahtuman aikana suuttimessa. TailOin kuitenkin lankojen pienennetyn kier-teityksen ansiosta yksittaisten saikeiden kuormitus ja 20 siten katkosten syntymisen vaara vahenevat.The method according to the invention can furthermore be designed in such a way that the yarn is given a thread of up to 150 T / m in the region of the texturing nozzle. In many cases, it is advantageous to make a thread in the yarn in the region of the texturing nozzle-15 less than 100 T / m. This threading ensures the desired beneficial effects when feeding the yarns into the texting nozzle as well as during the blowing operation itself in the nozzle. However, due to the reduced twisting of the wires, the load on the individual strands and thus the risk of breaks are reduced.
KeksinnOn mukainen menetelma voidaan lisaksi suun-nitella siten, etta lankaan tehdaan teksturointisuuttimen alueella Z- tai S-kierre. Teksturoituun lankaan saadaan taiia tavoin syntymaan erityinen vaikutus.The method according to the invention can furthermore be designed in such a way that a Z-thread or an S-thread is made in the region of the texturing nozzle. A special effect is created on the textured yarn in such a way.
25 Keksinnttn mukainen menetelma voidaan lisaksi suun- nitella siten, etta ensimmaiselle syOtinlaitteelle sydte-taan kerrattuja ja/tai kertaamattomia lankoja. Materiaa-leja ja lankojen kierteita yhteensovittamalla saadaan syn-nytettaviin, teksturoituihin lankoihin syntymaan aivan 30 erityisia ominaisuuksia erityisesti lujuuden, joustavuuden ja tilavuuden suhteen.The method according to the invention can furthermore be designed in such a way that twisted and / or non-twisted yarns are fed to the first feeding device. By combining the threads of the materials and the yarns, the textured yarns to be created give rise to very 30 special properties, especially in terms of strength, flexibility and volume.
Keksinn6n mukainen menetelma voidaan toteuttaa : laitteella, jossa teksturointisuuttimen ja toisen syOtin- laitteen vaiiin on asetettu valekierrin, jonka ohjauskap-35 paleena toimii akselinsa ympari kiertyvasti laakeroitu 4 90357 kiertotappi, jolloin tamån akseli on kaliellaan lankojen kulkusuuntaan nShden ja jonka halkaisija on suurempi kuin 4 mm.The method according to the invention can be implemented: with a device in which a pseudo-thread is placed between the texturing nozzle and the second feeder, the guide piece of which is a rotatably mounted pivot pin 90357 rotating about its axis, the axis being caliber in the direction of travel nShden and having a diameter greater than 4 mm .
Kiertotapin kiertyvSn laakeroinnin vålityksellå 5 vSltetaan yksittaisten lankojen kitka ja siten niiden ra-sittuminen valekiertimen lapimenon yhteydessS. Langat voi-daan tailttin ohjata siten, etta kiertotapin lapimenon yh-teydessa vaitetaan kierteiden vaiisia kosketuksia. Kiertotapin kallistus lankojen kulkusuuntaan nahden estaa langan 10 kierteiden vaiiset kosketukset kiertotapin lapimenon koh-dalla ja siten saastaa myOs materiaalia. 4 mm ylittava halkaisija tekee mahdolliseksi myfis verraten hauraiden materiaalien kasittelyn.By means of the rotating bearing 5 of the pivot pin, the friction of the individual wires and thus their stressing in connection with the passage of the false rotor is avoided. The threads can be guided in such a way that silent contacts of the threads are silenced during the passage of the pivot pin. The inclination of the pivot pin with respect to the direction of travel of the wires prevents the threaded contacts of the threads of the wire 10 at the passage of the pivot pin and thus contaminates the myOs material. The diameter exceeding 4 mm makes it possible to handle relatively brittle materials.
Laite voidaan suunnitella sellaiseksi, etta vale-15 kiertimen etaisyytta teksturointisuuttimesta voidaan saa- taa.The device can be designed so that the distance of the Vale-15 rotor from the texturing nozzle can be obtained.
Ammattimiehelle lienee itsestaanselvyys, etta yk-sittaisten mittojen, kuten esimerkiksi kiertotapin halkai-sijan, valekiertimen sijainnin teksturointisuuttimeen néh-20 den seka syiitinlaitteilla tapahtuvien ohjausten saatO ja valinta taytyy sovittaa kyseisen materiaalin edellyttamiin vaatimuksiin seka langan titteriin.It will be obvious to a person skilled in the art that the acquisition and selection of individual dimensions, such as the diameter of the pivot pin, the position of the pseudo-rotator on the texturing nozzle, and the means of the coil devices must be adapted to the requirements of the material and the wire titer.
Seuraavassa osassa selitysta selitetaan keksinnOn mukaisen menetelman yhta suoritusmuotoa seka sen kanssa . 25 kaytettavaa laitetta.In the following part of the description, one embodiment of the method according to the invention is explained together with it. 25 devices to use.
Piirustuksissa kuvio 1 on keksinnOn mukaisen teksturointilaitteen kaavamainen esitys, ja kuvio 2 on kuva valekiertimesta ylhaaita pain ku-- 30 vion 1 nuolen A suunnasta.In the drawings, Figure 1 is a texturing of the invention, a schematic and Figure 2 is a view valekiertimesta ylhaaita pain ku-- pattern 30 from the direction of the arrow A 1.
Kuviossa 1 kuvatussa suoritusmuodossa syOtetaan kolme kierteetttnta lankaa 1, 2, 3 monisaikeina lankoina rakenteeltaan tavalliselle ensimmaiselle sydtinlaitteelle 4. Langat 1, 2, 3 joutuvat sydtinlaitteen 4 jaikeen tulo-35 aukon 5 kautta teksturointisuuttimeen 6, josta ne poistu- 90357 s vat poistoaukon 7 kautta. Langat 1, 2, 3 viedaén sitten valekiertimen 9 kautta toiselle syOtinlaitteelle 10, jolta ne vedetaan pois nuolen 11 suuntaisesti.In the embodiment illustrated in Fig. 1, three threaded yarns 1, 2, 3 are fed as multifilament yarns to a first core device 4 of conventional construction. . The yarns 1, 2, 3 viedaén then through the second syOtinlaitteelle valekiertimen 9 to 10, which are pulled out in the direction of the arrow 11.
Teksturointisuutin 6 on rakenteeltaan tunnettu.The structure of the texturing nozzle 6 is known.
5 Siina sen lapi viedyt langat 1, 2, 3 pOyhOtetaan sinansa tunnetulla tavalla paineilraan puhaltamisen valitykselia.5 The wires 1, 2, 3 passed through it are blessed in a manner known per se with the complaint of blowing into the air.
Valekierrin 9 on varustettu ei-kuvatulla kayttd- i laitteella, joka saattaa valekiertimen 9 pydrimaan kulje-tussuunnan mydtaisen akselin ympari. Kiertimessa on rengas 10 12, joka kannattaa kiertotappia 13, joka puolestaan on laakeroitu renkaan 12 sateen suuntaisen akselin ympari va-paasti nuolen 14 mukaisesti kiertyvasti. Kiertotapin 13 akseli ei sijaitse poikittain lankojen kulkusuuntaan nah-den vaan on kallellaan sita kohti.The bogie 9 is provided with a non-described drive device which causes the bogie 9 to rotate about the mythical axis of the conveying direction. The spindle 12 is a ring 10 which carries a pivot 13, which in turn is mounted in a ring 12 of radial axis of the VA freely arrow 14 in a rotatable manner. The axis of the pivot pin 13 is not located transversely to the direction of travel of the wires, but is inclined towards it.
15 Langat muodostavat kiertotapin 13 kohdalla silmu- kan, jonka alku ja paa eivat kiertotapin 13 kallistuman vuoksi kosketa toisiaan. Kiertotappi 13 kiertyy lankojen kulkunopeuden mukaan. Suhteellinen nopeus toisaalta kiertotapin 13 ulkopinnan ja toisaalta lankojen valilia on 20 nolla.At the pivot pin 13, the wires form a loop, the beginning and end of which do not touch each other due to the inclination of the pivot pin 13. The pivot pin 13 rotates according to the travel speed of the wires. The relative speed of the outer surface of the pivot pin 13 on the one hand and of the wires on the other hand 20 is zero.
Valekiertimen 9 etåisyytta teksturointisuuttimesta 6 voidaan saataa, jotta laite voidaan sovittaa kulloinkin vallitseviin olosuhteisiin materiaalin ja langan titterin suhteen.The distance of the false twist 9 from the texturing nozzle 6 can be obtained so that the device can be adapted to the prevailing conditions with respect to the material and the titer of the yarn.
25 Sydtinlaitteiden 4, 10 vetonopeudet on tunnetulla tavalla sovitettu toisiinsa, jotta materiaalin pOyhottymi-. , sen vuoksi syntyvS lyheneminen tulee huomioiduksi.The drawing speeds of the core devices 4, 10 are arranged in a known manner in order to increase the material. , therefore the resulting shortening will be taken into account.
Kuvioiden mukaisessa suoritusmuodossa langat 1, 2, 3 syOtetaan siis ensimmSisen sydtinlaitteen 4 ja tekstu-30 rointisuuttimen 6 kautta valekiertimelle 9. Valekiertimen 9 kiertymisen johdosta langat 1, 2, 3 saavat kierteen, jo-' ka jaa edullisesti alle 100 T/m. Talla tavoin kootaan syd- tinlaitteelle 4 yksitellen sydtetyt langat 1, 2, 3 yhdeksi suljetuksi yksikdksi, jollaisena ne vedetaan sisaan teks-35 turointisuuttimeen 6 sen tuloaukolla 5. Lankoihin tehtyjen , 90357Thus, in the embodiment according to the figures, the yarns 1, 2, 3 are fed via a first core device 4 and a text-nozzle 6 to a spool 9. Due to the rotation of the spool 9, the yarns 1, 2, 3 preferably have a thread which preferably distributes less than 100 T / m. In this way, the individually wired yarns 1, 2, 3 on the carding device 4 are assembled into one closed unit, as they are drawn into the tex-35 holding nozzle 6 at its inlet 5. The 90357
