Description
15 20 25 30 35 40 7803028-5 igenom nypet. 15 20 25 30 35 40 7803028-5 through the nip.
Därvid användes såsom kärntråd i regel en ändlös fiber, eller ett redan framställt garn, vilket visserligen höjer det framställda garnets draghållfasthet, men strukturen hos det färdiga garnet förändras i många fall på ett icke önskat sätt. Det är inte möjligt att framställa ett fint garn med denna metod. Man kan, såsom garnkärna även använda en fibersträng, vilket dock medför att man endast kan framställa förhållandevis tjocka garnkvaliteter, emedan fibersträngen normalt endast finns i en grovleksordning av No l - 2. 1 Man kan visserligen förspänna strängen i hög grad, men sam- tidigt måste därvid strängen samtidigt spinnas, emedan den i endast sträckt tillstånd inte låter sig matas. Ändamålet med föreliggande uppfinning är således att förbättra en anordning av ovan angivet slag på så sätt att den medger hög matningshastighet, samtidigt som mycket fina garner skall kunna framställas.In this case, an endless fiber, or an already produced yarn, is generally used as the core thread, which, although the tensile strength of the produced yarn is increased, the structure of the finished yarn changes in many cases in an undesired manner. It is not possible to produce a fine yarn with this method. As a yarn core, a fiber strand can also be used, which, however, means that only relatively thick yarn grades can be produced, since the fiber strand is normally only available in a coarse order of No l - 2. 1 It is true that the strand can be prestressed to a great extent, but at the same time the string must be spun at the same time, since it cannot be fed in the stretched state only. The object of the present invention is thus to improve a device of the above kind in such a way that it allows a high feeding speed, at the same time as very fine yarns can be produced.
Detta uppnås enligt föreliggande uppfinning genom att spinn- anordningen_erhållit de i patentkraven.angivna kännetecknen.This is achieved according to the present invention in that the spinning device has obtained the features stated in the claims.
Fibersträngen kommer således att sträckas omedelbart framför de båda tvinnkropparna, vilka kan vara utformade såsom sugtrummor, men av vilka en även kan bestå av en roterande skiva eller dylikt.The fiber strand will thus be stretched immediately in front of the two twisted bodies, which may be designed as suction drums, but one of which may also consist of a rotating disc or the like.
Det kan även vara tillräckligt att endast den ena trumman är försedd med suganordning. Härvid kan fibersträngen matas med en hastighet på 300 m/minut eller mer och erhålla en 20- till 40-faldig sträck- ning, utan risk för strängens sammanhållning, p g a att den strax därefter, i nypet mellan de båda tvinnkropparna, får ett höljeskikt av det i nypet inmatade fibermaterialet. Sträckanordningens höga arbetshastighet medför naturligtvis även en motsvarande hög utmat- ningshastighet för det färdiga garnet, varvid, till följd av den höga försträckningen, även mycket tunna garn kan erhållas.It may also be sufficient that only one drum is provided with a suction device. In this case, the fiber strand can be fed at a speed of 300 m / minute or more and obtain a 20- to 40-fold stretch, without risk to the strand's cohesion, because shortly afterwards, in the nip between the two twisted bodies, it receives a casing layer of the fibrous material fed into the nip. The high working speed of the stretching device of course also results in a correspondingly high discharge speed for the finished yarn, whereby, due to the high pre-stretching, very thin yarns can also be obtained.
Då den uppsträckta strängen a ena sidan i sträckanordningen och å andra sidan i utmatningsanordningen, förhindras att vridas, nä» daxtvinnas mellan de båda tvinnkropparna tillsammans med inmnrndn fibrer, måste man antaga, ätt det här blott handlar om en .falsksnodd i strängen. Det har emellertid överraskande visat sig, att fibersträngen bibehåller den efter sträckanordninaen erhållna tvinningen, emedan de i nypet inmatade och i strängen tvinnade enskilda fibrerna förhindrar att strängen åter tvinnas upp mellan tvinnkropparna och utmatningsanordningen. Han 10 15 20 25 30 35 40 7803028-5. erhåller således ett garn med maximal draghâllfasthet, eftersom garnkärnan i huvudsak består av i garnets längdriktning orien- terade textilfibrer med ett lämpligt höljeskikt, varvid även yviga garner kan framställas, vilka trots mindre tvinning kommer att erhålla en tillräcklig hållfasthet.Since the stretched strand on the one hand in the stretching device and on the other hand in the discharge device is prevented from being twisted, then twisted between the two twine bodies together with inmnrndn fibers, it must be assumed that this is only a false knot in the strand. However, it has surprisingly been found that the fiber strand retains the twist obtained after the stretching device, since the individual fibers fed into the nip and twisted into the strand prevent the strand from being twisted up again between the twine bodies and the discharge device. Han 10 15 20 25 30 35 40 7803028-5. thus obtains a yarn with maximum tensile strength, since the yarn core mainly consists of textile fibers oriented in the longitudinal direction of the yarn with a suitable cover layer, whereby even bushy yarns can be produced, which despite less twisting will obtain a sufficient strength.
Såsom bekant är det nödvändigt att arbeta med desto mer parallella och sträckta fibrer ju högre nummer det framställda qarnet får, alltså ju finare garnet måste kunna spinnas- Därtill kommer även, att vid finare garn, dvs. med högre nummer, måste en i möjligaste mån stor likformighet finnas hos garnet, dvs. antalet enskilda textilfibrer i bredvid varandra liggande tvärsnitt hos garnet måste överensstämma, eftersom det totala antalet textilfibrer avtar med ökad garnfinhet. Genom fibersträngens sträckning kan man genom föreliggande uppfinning framställa garn i nummerserien upp till 80 eller mera, eftersom de ovan angivna fodringarna uppfylles.As is well known, it is necessary to work with the more parallel and stretched fibers the higher the number of the yarn produced, ie the finer the yarn must be able to be spun. In addition, with finer yarns, ie. with higher numbers, there must be as much uniformity as possible in the yarn, ie. the number of individual textile fibers in adjacent cross-sections of the yarn must correspond, since the total number of textile fibers decreases with increasing yarn fineness. By stretching the fiber strand, yarns in the number series up to 80 or more can be produced by the present invention, since the above linings are met.
Således kan, genom föreliggande uppfinning garn framställas med en hastighet på 300 m/minut eller mera, motsvarande sträck- anordningens arbetshastighet, medan moderna ringspinnmaskiner endast arbetar med garnhastigheter upp till 40 m/minut och moderna rotorspinnmaskiner, vid framställning av finare garn med No20,kan arbeta med en hastighet på 80 - 100 m/minut, varvid emellertid den översta gränsen i garnfinhet ligger på ungefär No 40..Thus, by means of the present invention yarns can be produced at a speed of 300 m / minute or more, corresponding to the working speed of the stretching device, while modern ring spinning machines only operate with yarn speeds up to 40 m / minute and modern rotor spinning machines, in producing finer yarns with No20, can work at a speed of 80 - 100 m / minute, however, the upper limit in yarn fineness is about No 40 ..
Uppfinningen skall nu beskrivas i anslutning till ett visat' utföringsexempel, där: fig. 1 visar ett tvärsnitt genom spinnanordningen vinkelrätt i garnmatningsriktningen och där fig. 2 visar en sidovy av anord- ningen där ena tvinnkroppen avlägsnats.The invention will now be described in connection with a shown exemplary embodiment, in which: Fig. 1 shows a cross section through the spinning device perpendicular to the yarn feeding direction and in which Fig. 2 shows a side view of the device where one of the twine bodies has been removed.
Textilfibrer matas in från en tandad kardtrumma l i nypet mellan de två tvinnkropparna, vilka består av två tätt bredvid varandra placerade, åt samma håll roterande sugtrummor 2. Varje sugtrumma 2 uppvisar en suganordning 3, vilka är placerade i an- slutning till nypet. Vid ena änden av trummorna är ett par rullar 5 anordnade för garnets utmatning, varvid garnet förhindras att vridas genom rullarnas 5 påverkan. Vid den motbelägna änden av trummorna 2 är en sträckanordning, bestående av flera rullpnr 6, 7, 8 direkt placerade, varvid rullarna 6, 7, 8 roteras med till- tagande periferihastighet, för att sträckeffekten skall uppnås.Textile fibers are fed from a toothed cardboard drum 1 into the nip between the two twisted bodies, which consist of two suction drums 2 placed close to each other, rotating in the same direction. Each suction drum 2 has a suction device 3, which are placed adjacent to the nip. At one end of the drums a pair of rollers 5 are arranged for the discharge of the yarn, whereby the yarn is prevented from being rotated by the action of the rollers 5. At the opposite end of the drums 2, a stretching device, consisting of several roller pins 6, 7, 8, is placed directly, the rollers 6, 7, 8 being rotated with increasing peripheral speed, in order to achieve the stretching effect.
Genom sträckanordningen 6, 7, 8 matas en fibersträng 9, via enThrough the tensioning device 6, 7, 8 a fiber strand 9 is fed, via a
