Description

Die Erfindung betrifft ein Verfahren zum Thermofixieren elastischer schlauchförmiger Textilware mit einem Anteil von natürlichen und einem Anteil von synthetischen Fasern, wobei die Textilware wenigstens eine erste Behandlungsstufe in gedehntem Zustand durchläuft. Solche Themofixier-Verfahren sind Z.B. aus US-A- 3909890 und WO-A- 80/01084 bekannt.The invention relates to a method for heat setting elastic tubular Textile goods with a share of natural and a share of synthetic fibers, wherein the textile goods at least a first treatment stage in the stretched state passes. Such topic fixing methods are e.g. out US-A-3909890 and WO-A-80/01084 are known.

In der Textiltechnik nehmen die Ausrüstungs- oder Veredelungsbehandlungen einen breiten und wichtigen Raum ein. Durch die Ausrüstung sollen an Garnen, Geweben, Wirkwaren, Strickwaren usw. die dem Rohmaterial anhaftenden Eigenschaften teils hervorgehoben, teils aber auch, falls sie weniger günstige Eigenschaften aufweisen, unterdrückt werden und der Ware nach ihrer Fertigung ihr endgültig gewünschter Charakter hinsichtlich der weiteren Verarbeitung oder ihres Gebrauchswertes bzw. ihres Aussehens verliehen werden.In textile technology, finishing or finishing treatments take on wide and important space. The equipment should be used on yarns, fabrics, Knitwear, knitwear, etc. some of the properties attached to the raw material highlighted, but sometimes also if they have less favorable properties, are suppressed and the goods are finally desired after their manufacture Character with regard to further processing or its use value or its Appearance.

Weitere Gesichtspunkte sind verwendungsabhängige Eigenschaften, wie z.B. wasserabweisend, knitterarm, schwer entflammbar, antistatisch usw. Ebenso vielfältig wie die Eigenschaften sind die bei der Ausrüstung eingesetzten mechanischen oder chemischen Mittel und Verfahren. Es ergeben sich vielfache Kombinationsmöglichkeiten je nach Art des zu behandelnden Materials; ebenso vielfältig sind die einsetzbaren Verfahren und Geräte. Kein Textilgut kann alle Verfahren, aber wenigstens mehrere der Verfahren nacheinander durchlaufen.Other aspects are use-dependent properties, such as water-repellent, crease-resistant, flame-retardant, antistatic, etc. Just as diverse like the properties are the mechanical or used in the equipment chemical agents and processes. There are many possible combinations depending on the type of material to be treated; the usable ones are just as diverse Procedures and devices. No textile can do all the processes, but at least several of them Go through the procedure one after the other.

Besondere Bedeutung erhält die Ausrüstung von Wirkwaren, Webwaren usw. durch die Einführung der synthetischen Werkstoffe in die Textiltechnik, denn durch die Eigenschaften der synthetischen Stoffe lassen sich vielfach über geeignete Ausrüstungsverfahren sowohl die Eigenschaften der natürlichen Stoffe als auch die Eigenschaften der synthetischen Stoffe verbessern. Die gefertigten Waren können dadurch besonders wertvoll werden. In der Praxis wird aber auch bereits deutlich, daß nicht sämtliche Ausrüstungsverfahren auf alle Textilmaterialien, wie Garne, Gewebe, Wirkware usw. unmittelbar oder in Kombination verwendbar sind.The finishing of knitted goods, woven goods, etc. is of particular importance Introduction of synthetic materials into textile technology, because through the Properties of the synthetic materials can often be determined using suitable ones Finishing process both the properties of natural substances and the Improve properties of synthetic materials. The manufactured goods can thereby becoming particularly valuable. In practice, however, it is already clear that not all finishing processes on all textile materials, such as yarns, fabrics, Knitwear etc. can be used directly or in combination.

Eines der wichtigsten Ausrüstungsverfahren für die Baumwollveredelung ist die Merzerisierung, bei der Garne und Gewebe aus Baumwolle mit starken Laugen (z.B. Natronlauge) unter Kühlung und Zugeinwirkung behandelt werden. Hierdurch erhält die Baumwolle seidenartigen Glanz, außer dem eine Erhöhung der Reißfestigkeit und Farbstoffaufnahmefähigkeit unter gleichzeitigem Verlust an Elastizität.One of the most important finishing processes for cotton finishing is the Mercerization, in the case of yarns and fabrics made of cotton with strong alkalis (e.g. Caustic soda) are treated with cooling and tension. This gives the Cotton silky sheen, besides an increase in tear resistance and Dyestuff absorption with loss of elasticity.

Als Beispiel für die Möglichkeiten der Merzerisierung sei die DE 29 40 867 C2 genannt. Dort sind in der Beschreibung des Standes der Technik und in der Beschreibung des Ausführungsbeispiels die verschiedensten Möglichkeiten für die Durchführung einer Merzerisation aufgeführt. So ist zum Beispiel der Schrift zu entnehmen, daß die Ware bahnförmig ausgebildet ist und breit geführt wird. Es kann sich dabei um flache oder offene Ware handeln oder auch um eine Schlauchware. Auf eine kontinuierliche oder eine diskontinuierliche Merzerisation ist hier hingewiesen. Dabei wird die Ware gedehnt und unter Querspannung transportiert. Für die Spannung sind Flachbreithalter oder auch Rundbreithalter für Schlauchware vorgesehen. Das Aufbringen des Behandlungsmediums erfolgt flüssig oder gasförmig durch Ringdüsen, die den Rundbreithalter umgeben. Auch eine Trocknung und eine mehrstufige Behandlung in mehreren aufeinander folgenden Behandlungsstufen ist dieser Druckschrift zu entnehmen.DE 29 40 867 C2 may be mentioned as an example of the possibilities for mercerization. There are in the description of the prior art and in the description of the Embodiment the most varied of ways to carry out a Mercerization listed. For example, it can be seen from the writing that the goods is web-shaped and is wide. It can be flat or trade open goods or tubular goods. On a continuous or discontinuous mercerization is indicated here. The goods are stretched and transported under transverse tension. For the tension are flat spreader bars or also Circular spreader intended for tubular goods. The application of the Treatment medium is liquid or gaseous through ring nozzles that the Circular spreader surround. Also drying and multi-stage treatment in This publication is entitled to several successive treatment stages remove.

In der Praxis wird ein flüssiges Behandlungsmedium nicht nur durch Aufsprühen oder Aufspritzen der zu behandelnden Warenbahn zugeführt, sondern die Ware kann insgesamt durch ein in einem Trog befindliches Flüssigkeitsbad hindurchgeführt werden.In practice, a liquid treatment medium is not only sprayed on or Spraying the web to be treated fed, but the goods can overall are passed through a liquid bath located in a trough.

Die Vielzahl der nur andeutungsweise aufgezeigten Ausrüstungsmaterialien und -verfahren zur Erreichung der unterschiedlichsten Ergebnisse bringt es naturgemäß mit sich, daß die Materialien oder Verfahren sich zum Teil stören. So haben sich bei der Behandlung von textiler Mischware die Erwartungen nicht im erhofften Umfang erfüllt. Bei Mischware z.B. enthalten die Garne einen Anteil aus natürlichen Fasern und einen Anteil aus synthetischen Fasern. Das Anteilsverhältnis kann dabei in weitem Umfang von Fall zu Fall verschieden sein. Die textilen Mischwaren sind vor allem wegen ihrer großen möglichen Elastizität als dehnbare Stretchware interessant. Durch Thermofixieren der Mischware in gedehntem Zustand können durch trockene Hitze oder heißen Dampf innere Spannungen beseitigt werden bzw. neue Formen verliehen werden, die nach dem Erkalten formbeständig sind. Die kurzzeitige Erwärmung der Mischware verhindert ein späteres Schrumpfen und Knittern der Ware und stabilisiert so die gewünschte Form (z.B. einen Kräuseleffekt). Dabei wird zwar die gewünschte Formbeständigkeit erfüllt, jedoch geht nach einer derartigen Ausrüstungsbehandlung der Mischware nach kurzer Zeit ein großer Teil der hohen Elastizität der Ware wieder verloren. Das zeigt sich nicht nur bei einer Merzerisierbehandlung, sondern auch bei anderen Ausrüstungsverfahren.The variety of equipment materials and only indicated - It naturally brings with it procedures for achieving a wide variety of results that the materials or processes interfere with each other. So with the Treatment of textile mixed goods did not meet expectations as expected. For mixed goods e.g. the yarns contain a portion of natural fibers and one Proportion of synthetic fibers. The proportion can vary widely be different from case to case. The textile mixed goods are mainly because of their great possible elasticity interesting as stretchable stretch fabric. By heat setting The mixed product can be stretched by dry heat or hot steam internal tensions are removed or new forms are given, which after the Colds are dimensionally stable. The brief heating of the mixed goods prevents later shrinking and creasing of the goods and thus stabilizes the desired shape (e.g. a ripple effect). The desired dimensional stability is met, however, after such finishing treatment of the mixed commodity, it takes a short time Time lost a large part of the high elasticity of the goods. That doesn't show only with a mercerization treatment, but also with other finishing processes.

Wird z.B. eine elastische textile Ware einem Grundausrüstungsverfahren mit einer oder mehreren Behandlungsstufen unterworfen und dabei in gedehntem Zustand geführt, so wird es der Gefahr ausgesetzt, in einer dieser Behandlungsstufen seine hohe Elastizität und damit seinen Vorteil zu verlieren.E.g. an elastic textile product with a basic equipment process or subjected to several treatment stages and carried out in a stretched state, see above it is exposed to the danger of being highly elastic in one of these treatment stages and thereby lose its advantage.

Der Erfindung liegt die Aufgabe zugrunde, bei der Anwendung solcher Ausrüstverfahren, die unter Dehnung ablaufen, die hohe Elastizität der Textilware zu bewahren. Dabei soll diese Forderung für einen großen Bereich des Mischungsverhältnisses der Fasern und auch bei den unterschiedlichsten synthetischen Materialien erfüllbar sein, und zwar unabhängig davon, bei welchem Grundausrüstungsverfahren die festgestellte Elastizitätsverschlechterung der Textilware vermieden werden soll. Außerdem soll eine geeignete Vorrichtung zur Durchführung des Verfahrens bereitgestellt werden.The invention has for its object in the application of such Finishing processes that take place under stretch increase the high elasticity of the textile goods preserve. This requirement is intended for a large area of Mixing ratio of the fibers and also with the most diverse synthetic Materials can be fulfilled, regardless of which one Basic finishing process the deterioration in elasticity of the textile goods should be avoided. In addition, a suitable device for performing the Procedure are provided.

Diese Aufgabe wird durch die Merkmale der Patentansprüche 1 und 9 gelöst. In dem für die Ware durchzuführenden Grundausrüstungsverfahren wird also vor derjenigen Behandlungsstufe, die eine Gefährdung für die Elastizität der Textilware darstellt, eine zusätzliche Behandlungsstufe eingeführt. Durch die Erwärmung und sofortige anschließende Abkühlung wird nur eine relativ kurze Behandlungsdauer in der zusätzlichen Behandlungsstufe erforderlich und es tritt im Verlauf des gesamten Grundausrüstungsverfahrens für die Textilware keine ins Gewicht fallende Verzögerung ein. Bei der zur Durchführung des Verfahrens notwendigen Vorrichtung kann die genannte zusätzliche Behandlungsstufe separat aufgebaut sein oder aber gegebenenfalls in der für die betreffende erste Behandlungsstufe bzw. des Grundausrüstungsverfahrens vorgesehenen Vorrichtung integriert sein.This object is solved by the features of claims 1 and 9. In the for the goods to be carried out basic equipment procedure is therefore before that Treatment level, which is a threat to the elasticity of the textile goods, a additional treatment level introduced. By warming and instant subsequent cooling is only a relatively short duration of treatment in the additional treatment level is required and it occurs throughout the course Basic finishing process for the textile goods no significant delay on. In the device necessary to carry out the method, the mentioned additional treatment stage can be set up separately or if necessary in the first treatment stage or basic equipment procedure provided device be integrated.

In der beigefügten Figur ist der schematische Aufbau der zusätzlichen Behandlungsstufe und der in ihr ablaufende Verfahrensschritt schematisch dargestellt.In the attached figure is the schematic structure of the additional treatment stage and the process step running in it is shown schematically.

Im Ausführungsbeispiel sei angenommen, daß an einer Textilware von nicht näher beschriebener Zusammensetzung eine Grundausrüstungsbehandlung, d.h. eine erste Behandlungsstufe durchgeführt werden soll, und zwar eine Merzerisierbehandlung unter Verwendung von Rundbreithaltern, wie sie etwa der DE 29 40 867 C2 zu entnehmen ist. Der für die Elastizität der textilen Mischware maßgebliche Behandlungsbereich liegt bei den Rundbreithaltern der Merzerisieranlage. Die erfindungsgemäße zusätzliche Behandlungsstufe ist in der Zeichnung als solche allein dargestellt und mit V bezeichnet und wird in einem Gehäuse 1 ausgeführt. Die zu behandelnde Ware ist mit dicken strichpunktierten Linien eingezeichnet und mit W gekennzeichnet. Sie wird einem Wareneingang E in die zusätzliche Behandlungsstufe V als flache Bahn, d.h. als flach gelegter Schlauch, zugeführt, über Umlenkrollen 5 in das Innere des Gehäuses 1 eingeführt, dort über einen verstellbaren Rundbreithalter 3 geführt und dabei gedehnt, wie durch die Doppelpfeile angezeigt ist. Das Dehnungsverhältnis der Ware im Rundbreithalter 3 soll dabei mindestens dem Dehnungsverhältnis der ersten Behandlungsstufe entsprechen. Die Dehnung bleibt über die Länge des Breithalters 3 und damit auch über den nachfolgend beschriebenen, zwischen Erhitzungs- und Abkühlabschnitt liegenden Behandlungsraum gleichmäßig. Sodann wird die schlauchförmige Ware durch weitere Umlenkrollen 5' am Ausgang A der zusätzlichen Behandlungsstufe in Pfeilrichtung abgezogen und den Vorrichtungen der ersten Behandlungsstufe, zum Beispiel einer in der oben genannten DE 29 40 867 C2 beschriebenen Merzerisiermaschine, zur weiteren Bearbeitung zugeführt. Der Rundbreithalter wird im Gehäuse 1 im oberen Teil über eine Trägervorrichtung 2a und im unteren Teil über eine Trägervorrichtung 2b in seiner Position getragen. Dabei dienen die Rollenanordnungen 4a bzw. 4b zur Aufhängung des Rundbreithalters sowie zum Antrieb des Warentransportes bei der Behandlung. Im oberen Teil des Rundbreithalters, nachdem die Ware ihren gedehnten Zustand erreicht hat, sind Ringdüsen 13 so angeordnet, daß ein Behandlungsmedium 20 auf die Ware aufgebracht werden kann. Weiter unten, kurz bevor die Ware den Rundbreithalter 3 wieder verläßt und der Dehnungszustand wieder zurückgenommen wird, sind in entsprechender Weise wieder Ringdüsen 19 vorgesehen, die den Rundbreithalter 3 umschließen. Zwischen den beiden Ringdüsen 13 und 19 befindet sich der eigentliche Behandlungsraum 21 der zusätzlichen Behandlungsstufe V. Der gegenseitige Abstand der Ringdüsen 13 und 19 in Transportrichtung der Ware von oben nach unten und damit auch die Länge der Einwirkstrecke im Behandlungsraum 21 ist an sich gering, verglichen mit den Längen der Behandlungsstrecken und den Längen der Breithalter in der ersten Behandlungsstufe.In the exemplary embodiment it is assumed that a textile product is not closer composition described basic treatment, i.e. a first Treatment stage should be carried out, namely a mercerization treatment Use of circular spreader bars, as can be seen, for example, from DE 29 40 867 C2. The treatment area relevant for the elasticity of the mixed textile goods is included the circular spreaders of the mercerising system. The additional according to the invention Treatment stage is shown in the drawing as such alone and is marked with V. and is carried out in a housing 1. The goods to be treated are thick dash-dotted lines and marked with W. It becomes one Goods receipt E in the additional treatment stage V as a flat path, i.e. as flat placed hose, fed, via deflection rollers 5 into the interior of the housing 1st introduced, guided over an adjustable circular spreader 3 and stretched in the process, as indicated by the double arrows. The stretch ratio of the goods in Circular spreader 3 should be at least the expansion ratio of the first Treatment level. The stretch remains over the length of the spreader 3 and thus also over the one described below, between heating and Cooling section lying treatment room evenly. Then the tubular goods by further deflecting rollers 5 'at the exit A of the additional Treatment stage deducted in the direction of the arrow and the devices of the first Treatment stage, for example one in DE 29 40 867 C2 mentioned above described mercerizing machine, fed for further processing. The Circular spreader is in the housing 1 in the upper part via a carrier device 2a and carried in position in the lower part by a carrier device 2b. Serve the roller assemblies 4a and 4b for hanging the rotary spreader and Drive the transport of goods during treatment. In the upper part of the circular spreader, after the goods have reached their stretched state, ring nozzles 13 are like this arranged that a treatment medium 20 can be applied to the goods. Further below, just before the goods leave the rotary spreader 3 and the Elongation is again in a corresponding manner Ring nozzles 19 are provided which enclose the circular spreader 3. Between the two Ring nozzles 13 and 19 are the actual treatment room 21 of the additional Treatment stage V. The mutual distance between the ring nozzles 13 and 19 in Direction of transport of the goods from top to bottom and thus also the length of the Actual distance in the treatment room 21 is small in itself compared to the lengths the treatment distances and the lengths of the spreader bars in the first treatment stage.

Am Wareneingang E und am Warenausgang A ist Vorsorge getroffen, daß das Innere der zusätzlichen Behandlungsstufe V bzw. daß der Behandlungsraum 21 nach außen hin gegen Wärmeverlust abgedichtet ist. So ist am Wareneingang E ein Zufuhrkasten 7 vorgesehen, der mit einer Abdichtflüssigkeit 6 gefüllt ist, wobei die Ware an einer Umlenkwalze 5 vollständig in die Flüssigkeit eintaucht und die Flüssigkeit siphonartig eine Abdichtung zwischen dem Inneren der zusätzlichen Behandlungsstufe V und dem Außenraum durchführt. Am Warenausgang A ist in entsprechender Weise ein Trog 8 vorgesehen, in dem die Ware beim Verlassen der zusätzlichen Behandlungsstufe V über Umlenkwalzen 5' abgezogen wird. Dieser Trog 8 ist als ebenfalls siphonartiger Badtrog ausgebildet, in dem die Ware in ein Bad mit dem Behandlungsmedium 20 eintaucht. Während in diesem Bad bzw. an dieser Abdichtstelle das in der zusätzlichen Behandlungsstufe verwendete flüssige Behandlungsmedium zur Verfügung steht, kann an der Zufuhrstelle am Wareneingang ein anderes flüssiges Abdichtmittel Verwendung finden.At goods receipt E and at goods issue A, provision is made for the inside of the additional treatment level V or that the treatment room 21 to the outside is sealed against heat loss. There is a feed box 7 at goods receipt E. provided, which is filled with a sealing liquid 6, the goods at one Deflection roller 5 is completely immersed in the liquid and the liquid siphon-like a seal between the interior of the additional treatment stage V and the Outside space. At the goods issue A there is a trough 8 in a corresponding manner provided in which the goods when leaving the additional treatment stage V over Deflection rollers 5 'is withdrawn. This trough 8 is also a siphon-like bath trough trained in which the goods are immersed in a bath with the treatment medium 20. While in this bath or at this sealing point this is in the additional Treatment level used liquid treatment medium is available, can Use a different liquid sealant at the delivery point at the goods receipt Find.

Vom Badtrog 8 als Sammelstelle bzw. Vorratsbehälter für das flüssige Behandlungsmedium 20 ausgehend, führt einerseits über eine Pumpe 10 in der durch Pfeile gekennzeichneten Transportrichtung eine Förderleitung 9 zu einer Erhitzungseinrichtung 11. Dort wird das Behandlungsmedium soweit erhitzt und über einen Regler 12 den Ringdüsen 13 zugeführt, daß die Ware W im Bereich der Ringdüsen 13 etwa auf die Erweichungstemperatur der synthetischen Fasern der zu behandelnden elastischen Textilware oder auch auf eine oberhalb davon liegende Temperatur erwärmt wird. Andererseits führt vom Trog 8 ausgehend ein anderer Zweig einer Förderleitung 14 über eine Pumpe 15 zu einer Kühlvorrichtung 16 und weiter zu den Ringdüsen 19. Die Zu- und Abfuhrleitungen des Kühlmittels sind mit 17 bzw. 17' sowie die Wirkungsrichtung durch Pfeile angedeutet. Das gekühlte Behandlungsmedium 20 wird dann den Ringdüsen 19 zugeführt und von dort auf die zu behandelnde und unter Dehnung gehaltene Ware gesprüht. Vom Behandlungsraum 21 aus kann sich das Behandlungsmedium 20 wieder im Trog 8 sammeln. Das Behandlungsmedium wird also vom Trog 8 ausgehend in einem ersten Erhitzungszweig 9 und in einem zweiten Abkühlungszweig 14 im Kreislauf geführt. Durch ein Thermometer 18 ist angedeutet, daß die Temperaturen je nach Bedarfszweck einstellbar bzw. regelbar sind. Die in Frage kommenden Temperaturbereiche sind abhängig einerseits von den Materialeigenschaften und andererseits von den in der ersten Behandlungsstufe verwendeten Arbeitstemperaturen. Es hat sich im Betrieb herausgestellt, daß die Temperatur des Erwärmungsteiles in der erfindungsgemäßen zusätzlichen Behandlungsstufe etwa 50 °C oberhalb der für die erste Behandlungsstufe benötigten Temperatur liegen soll. Dieser Bereich entspricht im wesentlichen der Erweichungstemperatur der verwendeten synthetischen Faser der Textilware. Für die schockartige Abkühlung ist als Temperatur für das Abschrecken der Ware ein Bereich von wenigstens 80 °C unterhalb der in der ersten Behandlungsstufe für die Ware benötigten Ausrüstungstemperatur vorteilhaft. Eine rasche Erhitzung des synthetischen Faseranteils wird dann erreicht, wenn das Behandlungsmedium als überhitzter Dampf auf die Ware aufgebracht wird. Durch die Verfahrensschritte "kurzfristige Erhitzung" der schlauchförmigen Textilware mit gleich darauf folgender "Abschreckung" bleibt die volle Elastizität der elastischen Textilware voll erhalten, wenn die zusätzliche Behandlungsstufe bei einer Temperatur erfolgt, die oberhalb der erste Behandlungsstufe liegt, die normalerweise die Elastizität der Textilware gefährdet. Es sei noch erwähnt, daß sich durch den aufgezeigten zusätzlichen Verfahrensschritt nicht nur Textilware mit bestimmtem Verhältnis von natürlichem zu synthetischem Faseranteil innerhalb der einzelnen Fäden behandeln läßt, sondern sich das Verfahren auch dann anwenden läßt, wenn die Textilware aus reinen natürlichen (z.B. Baumwoll-) Fäden und reinen synthetischen Fäden zusammengesetzt ist. Auch in diesem Fall können unterschiedliche natürliche und unterschiedliche synthetische Fasermaterialien in unterschiedlichen Anteilskombinationen und Anordnungskombination eingesetzt werden.From the bath tub 8 as a collection point or storage container for the liquid Starting treatment medium 20, on the one hand, leads through a pump 10 in the Arrows marked transport direction a conveyor line 9 to a Heating device 11. There the treatment medium is heated up to and over a controller 12 fed to the ring nozzles 13 that the goods W in the area of the ring nozzles 13 about the softening temperature of the synthetic fibers to be treated elastic textile goods or heated to a temperature above it becomes. On the other hand, another branch of a delivery line 14 leads from the trough 8 via a pump 15 to a cooling device 16 and further to the ring nozzles 19. Die Supply and discharge lines of the coolant are 17 and 17 'and the Direction of action indicated by arrows. The cooled treatment medium 20 becomes then fed to the ring nozzles 19 and from there to the one to be treated and below Stretched goods sprayed. From the treatment room 21 that can Collect treatment medium 20 again in trough 8. So the treatment medium starting from the trough 8 in a first heating branch 9 and in a second Cooling branch 14 out in circulation. A thermometer 18 indicates that the temperatures can be adjusted or regulated depending on the purpose. The one in question upcoming temperature ranges depend on the one hand on the material properties and on the other hand from those used in the first treatment stage Working temperatures. It has been found in operation that the temperature of the Heating part in the additional treatment stage according to the invention about 50 ° C. should be above the temperature required for the first treatment stage. This Range essentially corresponds to the softening temperature of the one used synthetic fiber of textile goods. For the shock-like cooling is as temperature for quenching the goods, a range of at least 80 ° C below that in the first treatment stage for the equipment temperature required advantageous. A rapid heating of the synthetic fiber portion is achieved when that Treatment medium is applied to the goods as superheated steam. Through the Process steps "short-term heating" of the tubular textile goods with the same the following "deterrence" remains the full elasticity of the elastic textile goods fully preserved if the additional treatment step is at a temperature that is above the first treatment level, which is usually the elasticity of the Textile goods at risk. It should also be mentioned that the additional Process step not only textile goods with a certain ratio of natural to synthetic fiber content within the individual threads can be treated, but the method can also be used if the textile product is made of pure natural (e.g. cotton) threads and pure synthetic threads. Also in In this case, different natural and different synthetic Fiber materials in different proportions and combinations Arrangement combination can be used.
