Abstract

1. A continuous process for eliminating undersirable longitudinal distortion in textiles, for example woven, Raschel or knitted webs of material of tubular shape or of open, flat form, of natural fibres, in particular cotton, which optionally may contain a proportion of synthetic fibres, by stretching the web of material in width in a controlled manner while it is in a moist condition and overfeeding it in the longitudinal direction by forward movement, characterized in that the web of material is heated while being overstretched, in that the overfeed is at least as great as the overstretching in width, and in that the web or material undergoes forced cooling prior to leaving the apparatus for stretching in width.

Description

Die Erfindung betrifft ein Verfahren zum Beseitigen des unerwünschten Längsverzugs in textilen, zum Beispiel gewebten, geraschelten oder gewirkten Warenbahnen in Schlauchform bzw. in offener, breitliegender Form aus natürlichen Fasern, insbesondere aus Baumwolle, die gegebenenfalls einen Anteil an Kunstfasern enthalten, indem die Warenbahn in feuchtem Zustand kontrolliert in Breitenrichtung überdehnt wird. Sie betrifft ferner Vorrichtungen zur Durchführung des Verfahrens.The invention relates to a method for eliminating the undesirable longitudinal distortion in textile, for example woven, shaved or knitted webs in tubular form or in open, wide-lying form made of natural fibers, in particular cotton, which may contain a proportion of synthetic fibers by the web in damp condition is controlled overstretched in the width direction. It also relates to devices for performing the method.

Textile Warenbahnen, gleichgültig ob gewebt, geraschelt oder gewirkt, verlassen die Maschinen mit inneren Spannungen. Die späteren Veredelungsstufen, wie Waschen, Bleichen und Färben, vor allem aber das unvermeidbare, wiederholte Beschicken und Entladen der Maschinen unter Warenzug, strecken die Warenbahn zusätzlich in die Länge und dehnen das Garn. Diese forcierte Naßverformung kann derzeit weder im Trockner noch im Dämpfkalander zufriedenstellend und mit vertretbarem Aufwand ausgeglichen werden. Erst bei der Hauswäsche der fertigen Kleidungsstücke entspannen sich Garn und Stoff restlos. Das Wäschestück läuft ein.Textile webs, regardless of whether they are woven, rustled or knitted, leave the machine with internal tension. The later finishing stages, such as washing, bleaching and dyeing, but above all the unavoidable, repeated loading and unloading of the machines under goods train, also stretch the web into Length and stretch the yarn. This forced wet deformation can currently neither be satisfactorily compensated for in the dryer nor in the steam calender and with reasonable effort. The yarn and fabric only relax completely when the finished garments are washed at home. The piece of laundry comes in.

Zur Beseitigung dieses unerwünschten Längsverzugs wird unter anderem eine stabilisierende Gegenverformung im feuchten Zustand angewendet. Hierzu reckt man die feuchte Warenbahn kontrolliert in die Breite. Dabei verformt sie sich in die Breite und wird kürzer. Die Ware wird kompaktiert. Während eines anschließenden spannungslosen Trockenvorgangs wird auch das Garn entspannt. Dabei soll die bewußt erzeugte Überbreite auf das Normalmaß einspringen, das gedehnte Garn soll sich entspannen und die durch das Kompaktieren reduzierte Länge plus evtl. zusätzlichem Maschinentrocknungsschrumpf soll stabilisiert werden.To eliminate this undesirable longitudinal distortion, a stabilizing counter-deformation in the moist state is used, among other things. To do this, stretch the damp web in a controlled manner. In doing so, it deforms in width and becomes shorter. The goods are compacted. The yarn is also relaxed during a subsequent tension-free drying process. The deliberately created excess width should jump to the normal size, the stretched yarn should relax and the length reduced by the compacting plus any additional machine drying shrinkage should be stabilized.

Bei richtiger Verfahrensführung entsteht am Ende ein natürliches, entspanntes Gewebe bzw. Gewirk, welches die entscheidende Voraussetzung für niedrige Restschrumpfwerte und hohe Formstabilität der konfektionierten Kleidungsstücke ist.If the process is carried out correctly, a natural, relaxed fabric or knitted fabric is created, which is the decisive prerequisite for low residual shrinkage values and high dimensional stability of the garments.

Leider hat sich gezeigt, daß die Hersteller der Warenbahnen versuchen, die abzuliefernde Breite mit möglichst wenig Garn und Maschenzahl zu erreichen. Deshalb wird die entspannte Warenbahn nach dem Trocknen wieder auf die Sollbreite gebracht, mit der Folge, daß die aus diesem Material konfektionierten Kleidungsstücke in der Haushaltswäsche wieder eingehen. Obwohl dies bekannt ist, wird es in der Branche allgemein toleriert, da es offensichtlich derzeit kein brauchbares Verfahren gibt, mit dem die sich widerstreitenden Forderungen erfüllen lassen.Unfortunately, it has been shown that the manufacturers of the webs try to achieve the width to be delivered with as little yarn and number of stitches as possible. Therefore, the relaxed fabric is brought back to the desired width after drying, with the result that the garments made of this material are included in the household linen again. Although this is known it is generally tolerated in the industry, as there is apparently currently no viable process to meet the conflicting demands.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, das Verfahren der eingangs genannten Art dahingehend zu verbessern, daß Restschrumpfwerte im Bereich von 0 % bei gleichzeitig größerer Breite und niedrigerem Flächengewicht der Warenbahn erreicht werden können.The present invention is therefore based on the object of improving the method of the type mentioned at the outset such that residual shrinkage values in the range of 0% can be achieved with a simultaneously greater width and lower basis weight of the web.

Diese Aufgabe wird dadurch gelöst, daß die Warenbahn im erhitzten Zustand überdehnt wird und daß der Vorlauf wenigstens so groß ist wie die Breitendehnung.This object is achieved in that the web is overstretched in the heated state and that the lead is at least as large as the width expansion.

Damit ergeben sich die Vorteile, daß beim Uberdehnen in Breitenrichtung Gewebe bzw. Gewirk und Garn nicht nur mechanisch gegengespannt werden, sondern daß gleichzeitig die Molekülstrukturen des Garns - im Fall von Baumwolle sind es die O-OH- bzw. nebenvalente Bindungen der Zellulose - aufgebrochen werden. Hierdurch können die Spannungen, die in der Molekülstruktur der Garne manifestiert sind, ebenfalls entspannt werden, wobei der zusätzliche Aufwand verschwindentgering ist. Am Ende des nachgeschalteten Trockenvorgangs ist die Textilbahn trocken und entspannt. Außerdem behält die Warenbahn eine größere Breite als beim bisherigen Verfahren und ein günstiges, verringertes Flächengewicht. Das Uberdehnen wird zwischen 5 % und 150 % eingestellt, abhängig von Garnqualität, Gewebebindung, Wirkart usw. Bei Webware sind Werte zwischen 5 und 50 %, bei Raschelware Werte zwischen 10 und 80 % und bei Wirkwaren Werte bis 150 % typisch. Zu der Breitenüberdehnung muß ein entsprechender Vorlauf in Längsrichtung der Warenbahn eingestellt werden. Dabei werden Werte,die größer sind als die Werte der Breitenüberdehnung, bevorzugt.This has the advantages that when stretching in the width direction, the fabric or knitted fabric and yarn are not only mechanically counter-tensioned, but that at the same time the molecular structures of the yarn - in the case of cotton it is the O-OH or non-valent bonds of cellulose - are broken will. As a result, the tensions which are manifested in the molecular structure of the yarns can also be relaxed, with the additional outlay being eliminated. At the end of the subsequent drying process, the textile web is dry and relaxed. In addition, the web retains a larger width than in the previous method and a favorable, reduced basis weight. Overstretching is set between 5% and 150%, depending on the yarn quality, weave, type of knitting etc. Values between 5 and 50% are typical for woven goods, values between 10 and 80% for knitted goods and values up to 150% for knitted goods. To the latitude a corresponding advance in the longitudinal direction of the web must be set. Values that are larger than the values of the width expansion are preferred.

Das erfindungsgemäße Erwärmen der Warenbahn kann auf verschiedene Weisen erfolgen. Eine Möglichkeit besteht darin, die Warenbahn vor dem Uberdehnen durch ein heißes Bad zu leiten.The heating of the material web according to the invention can be carried out in various ways. One possibility is to pass the web through a hot bath before stretching.

In allen Fällen sollte der Feuchtigkeitsgehalt der Warenbahn zwischen 20 und ca. 150 % eingestellt werden, wobei die erhöhten Werte bevorzugt sind. Ausreichende Feuchtigkeitswerte verbessern den Entspannungseffekt durch Erwärmen noch zusätzlich.In all cases, the moisture content of the web should be set between 20 and about 150%, the higher values being preferred. Sufficient moisture levels additionally improve the relaxation effect by heating.

Die feuchte Warenbahn kann auch mit trockener Wärme erhitzt werden, insbesondere mit Infrarot-Strahlung oder auch mit Hochfrequenz-Energie. Es ist lediglich dafür zu sorgen, daß beim überschreiten der ReaktionsTemperatur die Warenbahn noch ausreichend feucht ist.The moist web can also be heated with dry heat, in particular with infrared radiation or also with high-frequency energy. It is only necessary to ensure that the web is still sufficiently moist when the reaction temperature is exceeded.

Vorzugsweise wird die Warenbahn auf Temperaturen zwischen 50° und 100 °C erhitzt. Die optimale Temperatur ist abhängig von der Art der natürlichen Fasern - Baumwolle oder Wolle - und der gegebenenfalls zugegebenen Kunstfasern. Beispielsweise bei Baumwolle mit Acrylfasern wird das erfindungsgemäße Verfahren bei 50 °C durchgeführt; handelt es sich um reine Baumwolle, so kann die Temperatur gefahrlos auf 100 °C, das ist die Temperatur von Sattdampf, gesteigert werden.The web is preferably heated to temperatures between 50 ° and 100 ° C. The optimal temperature depends on the type of natural fibers - cotton or wool - and any synthetic fibers added. For example, in the case of cotton with acrylic fibers, the process according to the invention is carried out at 50 ° C .; If it is pure cotton, the temperature can be safely increased to 100 ° C, which is the temperature of saturated steam.

Gemäß einer Weiterbildung des erfindungsgemäßen Verfahrens wird die Warenbahn vor dem Verlassen der Breitstreckvorrichtung bei bestimmten Qualitäten forciert gekühlt. Wie vorstehend schon erläutert, wird für die verbesserte Entspannung auch eine chemisch bedingte Veränderung der Molekülstruktur der natürlichen Fasern durch Aufbrechen und Neuformieren von Molekülketten verantwortlich gemacht. Durch das forcierte Kühlen am Ende des Breitstreckvorgangs werden diese chemischphysikalischen Vorgänge sofort gestoppt.According to a development of the method according to the invention, the material web is wide before it leaves Stretching device with certain qualities forced cooled. As already explained above, a chemically induced change in the molecular structure of the natural fibers by breaking up and reforming molecular chains is also responsible for the improved relaxation. Due to the forced cooling at the end of the spreading process, these chemical-physical processes are stopped immediately.

Eine bevorzugte Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens besteht darin, daß der Kompaktor mit einer Bedampfungsvorrichtung ausgestattet ist. Als Kompaktor ist jede handelsübliche, einwandfrei funktionierende Anlage geeignet, die durch Anbau einer Sattdampf-Bedampfungsvorrichtung in einfachster Weise zur Durchführung des erfindungsgemäßen Verfahrens umgerüstet werden kann. Am besten bewährt haben sich Nadelkluppen für offene, breitliegende Ware.A preferred device for carrying out the method according to the invention is that the compactor is equipped with a vapor deposition device. Any commercially available, perfectly functioning system is suitable as a compactor, which can be converted in a very simple manner to carry out the method according to the invention by attaching a saturated steam application device. Needle clips have proven to be the best for open, wide-lying goods.

Für Schlauchware wird ein üblicher Breithalter eingesetzt, vorzugsweise mit langen Backen, um die Warenbahn möglichst schonend behandeln zu können.A conventional spreader is used for tubular goods, preferably with long jaws, in order to be able to treat the web as gently as possible.

Eine andere, sehr einfache Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens besteht in der Ausstattung des Kömpaktors mit einer Infrarot-Heizung. Auch eine derartige Heizung ist in einfachster Weise montierbar und gegebenenfalls nachrüstbar.Another very simple device for carrying out the method according to the invention consists in equipping the body factor with an infrared heater. Such a heater can also be installed in the simplest way and retrofitted if necessary.

Soll die Warenbahn am Auslauf des Kompaktors forciert gekühlt werden, so erhalten die Vorrichtungen eine Abkühlvorrichtung, insbesondere eine über die gesamte Breite der Warenbahn sich erstreckende Düse für Kaltluft. Diese Kühlluft beseitigt gleichzeitig einen Teil des Feuchtigkeitsgehaltes der Warenbahn.If the material web is to be forced-cooled at the outlet of the compactor, the devices are provided with a cooling device, in particular a nozzle for cold air which extends over the entire width of the material web. This cooling air eliminates you at the same time Part of the moisture content of the web.

Anhand von Ausführungsbeispielen sollen das erfindungsgemäße Verfahren und die dabei erreichbaren, günstigen Ergebnisse erläutert werden.The method according to the invention and the favorable results which can be achieved thereby are to be explained on the basis of exemplary embodiments.

1. Beispiel1st example

Geraschelte Frottierware mit einem Flächengewicht von 300 - 330 g/m2 und einer Sollbreite von 1,62 m wurde zunächst der üblichen Naßbehandlung unterworfen. Die Warenbahn hatte danach eine Breite von 1,48 m und einen Restkrumpfwert in Breitenrichtung von ca. 15 %.Shredded terry towels with a basis weight of 300-330 g / m 2 and a nominal width of 1.62 m were first subjected to the usual wet treatment. The web then had a width of 1.48 m and a residual shrinkage value in the width direction of approx. 15%.

Die Warenbahn wurde anschließend mit Nadelkluppen gefaßt und gedehnt, wobei eine Breitenüberdehnung von ca. 30 % und ein Vorlauf von ebenfalls 30 % eingestellt wurden. Die überdehnte Ware wurde mit Sattdampf bedämpft und anschließend in herkömmlicher Weise spannungslos getrocknet. Sie hatte eine Endbreite von 1,58 m.The web was then gripped and stretched with pin clips, with a width expansion of approx. 30% and a lead of likewise 30%. The overstretched goods were steamed with saturated steam and then dried without tension in a conventional manner. It had a final width of 1.58 m.

Anschließend wurden nach der sogenannten Reutlinger Methode, d. h. mit dreimaligem Waschen und Trocknen in Haushaltsmaschinen, die Eigenschaften der Warenbahn bestimmt. Dabei ergaben sich Restkrumpfwerte in Länge und Breite von unter 2 %.Subsequently, according to the so-called Reutlinger method, i.e. H. washing and drying three times in household machines determines the properties of the web. This resulted in residual shrinkage values in length and width of less than 2%.

Als Vergleich dazu wurde die selbe Warenbahn herkömmlich getrocknet. Danach hatte sie Restkrumpfwerte von 3,5 % in der Breite und 6 % in der Länge, sowie eine Endbreite von 1,45 m. Um auf die Sollbreite zu kommen, müßte diese Bahn wieder um 12 % gedehnt werden.As a comparison, the same web was conventionally dried. After that she had residual shrinkage values of 3.5% in width and 6% in length, as well as a final width of 1.45 m. To get to the target width, this web would have to be stretched again by 12%.

2. Beispiel2nd example

Gewirkte Schlauchware mit einem Flächengewicht von ca. 120 g/m2 und einer Sollbreite von 16,5 cm wurde zunächst der üblichen Naßbehandlung unterworfen. Die Schlauchbahn hatte danach eine Breite von 16,5 cm.Knitted tubular fabric with a basis weight of approx. 120 g / m 2 and a nominal width of 16.5 cm was first subjected to the usual wet treatment. The tube track then had a width of 16.5 cm.

Diese Schlauchbahn wurde anschließend mit einem Breithalter mit langen Führungsbacken gedehnt, wobei eine Breitenüberdehnung von ca. 100 % und ein Vorlauf von ebenfalls 100 % eingestellt wurden. Die überdehnte Ware wurde an der breitesten Stelle mit Sattdampf bedämpft und anschließend in herkömmlicher Weise spannungslos getrocknet. Sie hatte dann eine Endbreite von 16 cm. Die Restkrumpfwerte in der Länge waren kleiner als 0,8 %, in der Breite ca. 2 %.This tubular web was then stretched using a spreader with long guide jaws, with a width expansion of approx. 100% and a lead of likewise 100%. The overstretched goods were steamed at the widest point with saturated steam and then dried without tension in a conventional manner. It then had a final width of 16 cm. The residual shrinkage values were less than 0.8% in length and approx. 2% in width.

Als Vergleich dazu wurde die selbe Warenbahn herkömmlich getrocknet. Danach hatte sie eine Endbreite von 14 cm und Restkrumpfwerte in der Länge von 5 bis 7 % und in der Breite von ca. 2 %. Um auf die Sollbreite zu kommen, müßte diese Bahn wieder um 14 % gedehnt werden.As a comparison, the same web was conventionally dried. After that it had a final width of 14 cm and residual shrinkage values in the length of 5 to 7% and in the width of approx. 2%. To get to the target width, this web would have to be stretched again by 14%.

Ein Vergleich der Meßergebnisse zeigt, daß das erfindungsgemäße Verfahren zu einem deutlich erhöhten Abbau der inneren Spannungen und gleichzeitig zu einem deutlich geringeren Schrumpf, insbesondere in Breitenrichtung, führt. Die Flächenstabilität wird höher, das Flächengewicht niedriger und erfüllt damit die Wünsche von Hersteller und Ausrüster.A comparison of the measurement results shows that the method according to the invention leads to a significantly increased reduction in the internal stresses and at the same time to a significantly lower shrinkage, in particular in the width direction. The area stability is higher, the area weight is lower and thus fulfills the wishes of the manufacturer and supplier.
