Abstract

In a process for compressing sheet-like textile structures in the longitudinal and transverse direction, highly shrinking and normal shrinking polyester yarns of the same chemical composition are processed to give a sheet-like structure. The sheet-like structure is subjected to thermal treatment at 60 to 200 DEG C without stress and exhibits a fabric shrinkage of at least 15%. The process is used for the production of woven, knitted and tufted materials and for the compression of pile materials.

Description

Die Erfindung betrifft ein Verfahren zum Verdichten von textilen Flächengebilden in Längs- und Querrichtung aus Polyestergarnen, wobei ein Teil aus hochschrumpfenden Polyesterfilamenten und ein Teil aus normalschrumpfenden Polyesterfilamenten zu einem Flächengebilde verarbeitet werden sowie ein Flachengebilde, hergestellt nach dem Verfahren und dessen Anwendung.The invention relates to a method for compressing textile fabrics in the longitudinal and transverse directions from polyester yarns, a part of shrinking polyester filaments and a part of normal shrinking polyester filaments being processed to form a sheet, and a sheet made by the method and its application.

Aus der GB-A-985451 sind zwartextile Artikel aus einem geschrumpften und einem ungeschrumpften Polyesterfilament bekannt, die resultierenden Gewebe weisen jedoch einen für ein dichtes Flächengebilde unerwünschten Crepe-Effekt auf.GB-A-985451 discloses two-textile articles made from a shrunk and an unshrunk polyester filament, but the resulting fabrics have an undesirable crepe effect for a dense sheet.

Durch Verdichten von textilen Flächengebilden, insbesondere von Geweben, kann die Durchlässigkeit für Wasser, Wasserdampf und Gase reduziert werden. Dichte Gewebe wirken wasserabstossend. Für Inletts ist für deren Gebrauch eine gute Gewebedichte eine unabdingbare Voraussetzung.The permeability to water, water vapor and gases can be reduced by compacting textile fabrics, in particular fabrics. Dense fabrics are water-repellent. A good tissue density is an essential prerequisite for Inletts.

Es wurden verschiedene Verfahren zum Verdichten von Geweben vorgeschlagen, welche sich die Kompressibilität von Kompositfasern, bestehend aus Polyester und Polyamid Mikrofibrillen zu Nutze machen. Die Einzelfibrillen weisen dabei einen Titer von weniger als 0,5 denier (=0,55 dtex) auf.Various methods for compacting fabrics have been proposed which take advantage of the compressibility of composite fibers consisting of polyester and polyamide microfibrils. The individual fibrils have a titer of less than 0.5 denier (= 0.55 dtex).

Es ist ein Verfahren bekannt (EP 0 092 938), das mit extrem feinen Fasern im Bereich von 0,001 bis 0,8 denier aus Polyester und Polyamid arbeitet, wobei die Polyamidkomponente mittels eines Quellmittels zuerst zum Quellen und anschliessend zum Schrumpfen gebracht wird.A method is known (EP 0 092 938) which works with extremely fine fibers in the range from 0.001 to 0.8 denier made of polyester and polyamide, the polyamide component being swelled first and then shrinking by means of a swelling agent.

Schon die Herstellung der extrem feinen Kompositfasern mit der erforderlichen Wasserbeständigkeit und Festigkeit ist problematisch und auf mehreren Wegen versucht worden. Hinzu kommt die Zugabe von Quellmitteln die in ihrer Toxizität weitere Einschränkungen in der Anwendung erforderlich machen.Even the production of the extremely fine composite fibers with the required water resistance and strength is problematic and attempts have been made in several ways. Added to this is the addition of swelling agents, which make further restrictions in use necessary in their toxicity.

Allen bekannten Verfahren gemeinsam ist die Verwendung von Garnmischungen bzw. Filamentmischungen, welche aus unterschiedlichen Rohstoffen hergestellt sind. Das hat den Nachteil, dass eine Vielzahl von unterschiedlichen Polymeren zur Verarbeitung gelangt und eine aufwendige analytische Qualitätskontrolle erforderlich ist. Auch sind bei unterschiedlichen Polymeren unterschiedliche Spinntechniken einzusetzen.Common to all known processes is the use of yarn blends or filament blends which are produced from different raw materials. This has the disadvantage that a large number of different polymers are processed and complex analytical quality control is required. Different spinning techniques can also be used with different polymers.

Es besteht schon lange das Bedürfnis aus einem einheitlichen Rohstoff, welcher leicht und preiswert zugänglich ist, ein ebenes textiles Flächengebilde herzustellen, welches auf einfache Weise soverdichtetwerden kann, dass seine Durchlässigkeit für Wasser und Luft gering ist. Es besteht aber auch das Bedürfnis die Spinntechnik resp. Strecktechnik weitgehend zu vereinfachen, um zu einem wirtschaftlichen Verfahren zu gelangen.There has long been a need to produce a flat textile fabric from a uniform raw material which is easily and inexpensively accessible, and which can be compacted in a simple manner so that its permeability to water and air is low. But there is also a need for spinning technology, respectively. To largely simplify stretching technology in order to arrive at an economical process.

Die Aufgabe wird erfindungsgemäss dadurch gelöst, dass die hochschrumpfenden Polyesterfilamente kaltverstreckte Polyester-POY mit einem Kochschrumpf von wenigstens 20 % sind.The object is achieved according to the invention in that the shrinking polyester filaments are cold-drawn polyester POY with a cooking shrinkage of at least 20%.

Die thermische Behandlung des Flächengebildes erfolgt spannungslos zwischen 60 und 200°C in einer gasförmigen oder flüssigen Umgebung. Dabei hat sich ein Temperaturbereich von 80 bis 1800C als am zweckmässigsten erwiesen. In einer bevorzugten Verfahrensweise wird das Flächengebilde im Wasser von 95 bis 98°C schockartig behandelt.The thermal treatment of the fabric is stress-free between 60 and 200 ° C in a gaseous or liquid environment. A temperature range from 80 to 180 ° C. has proven to be the most expedient. In a preferred procedure, the fabric is shock-treated in water from 95 to 98 ° C.

Dabei ist darauf zu achten, dass der Hochschrumpffaden während der Verarbeitung zum textilen Flächengebilde nicht gedämpft oder warm geschlichtet oder anderweitig thermisch vorbehandelt werden darf.Care must be taken to ensure that the shrink thread is not steamed or heat-sized or otherwise thermally pretreated during processing into a textile fabric.

Das erfindungsgemässe Verfahren hat unter anderem den Vorteil, dass das Garn dem Hersteller des Flächengebildes eine einfachere Verarbeitung erlaubt. Es muss beispielsweise zum Erreichen einer höchstmöglichen Schussdichte nicht bei entsprechend hoher Kettspannung gearbeitet werden, durch die Fadenbrüche entstehen können. Die Verdichtung erfolgt ohne Bauscheffekt.The method according to the invention has the advantage, among other things, that the yarn allows the manufacturer of the fabric to be processed more easily. For example, in order to achieve the highest possible weft density, it is not necessary to work with a correspondingly high warp tension, which can cause thread breaks. The compression takes place without a building effect.

Aus dem gleichen Polymer werden sowohl kalt wie warmverstreckte Polyesterfäden hergestellt.Both cold and hot drawn polyester threads are made from the same polymer.

Unter einem kaltverstrecktem Polyester-POY ist ein Faden zu verstehen, welcher wenigstens 90 Gew.-% Polyethylenterephthalat enthält und mit einer Geschwindigkeit von etwa 3100 m/min gesponnen und anschliessend unterhalb des Glasumwandlungspunktes verstreckt wurde.A cold-drawn polyester POY is to be understood as a thread which contains at least 90% by weight of polyethylene terephthalate and which has been spun at a speed of approximately 3100 m / min and then drawn below the glass transition point.

Die verwendeten kaltverstreckten Polyester-POY-Fäden weisen einen Kochschrumpf von 20 bis 60 % auf, vorzugsweise 30 bis 50 %, bezogen auf die Ausgangslänge des Fadens.The cold-drawn polyester POY threads used have a cooking shrinkage of 20 to 60%, preferably 30 to 50%, based on the starting length of the thread.

Unter warmverstrecktem Polyester sind alle Fäden zu verstehen, welche entweder im Splitverfahren oder im Continue-Verfahren produziert wurden, wenigstens 90 Gew.-% Polyethylenterephthalat enthalten und oberhalb des Glasumwandlungspunktes verstreckt wurden. Alle diese Fäden haben einen Kochschrumpf <20 %.Warm-drawn polyester is to be understood to mean all threads which have been produced either by the split process or by the continue process, contain at least 90% by weight of polyethylene terephthalate and have been drawn above the glass transition point. All of these threads have a cooking shrinkage <20%.

Das verdichtete Flächengebilde besteht aus kaltverstreckten und warmverstreckten Polyesterfäden. Die kaltverstreckten Fäden können in der Kette und/oder im Schuss eingesetzt werden. Je nachdem erfolgt die Verdichtung in Schuss- oder Kettrichtung. Das Flächengebilde wird in bekannter Weise einer spannungslosen thermischen Schockbehandlung unterzogen, wodurch eine Verdichtung durch Schrumpfen der kaltverstreckten Fäden resultiert.The compacted fabric consists of cold-drawn and warm-drawn polyester threads. The cold drawn threads can be used in the warp and / or in the weft. Depending on the compression in the weft or warp direction. The fabric is subjected to stress-free thermal shock treatment in a known manner, which results in compression by shrinking the cold-drawn threads.

Selbstverständlich können die hier angesprochenen Flächengebilde neben Polyesterfilamentgarnen auch andere Fasern enthalten.Of course, the fabrics mentioned here can also contain other fibers in addition to polyester filament yarns.

Der Warenschrumpf beträgt längs und/oder quer wenigstens 10 %, bevorzugt 20 bis 30 %, bezogen auf die Ausgangsdimensionen. Ein solcher Schrumpf bewirkt eine Dichte, welche die Luft- und Wasserdurchlässigkeit so weit herabsetzt, dass unter Umständen sogar auf eine chemische Behandlung, beispielsweise in Form einer Beschichtung oder Imprägnierung, verzichtet werden kann.The lengthwise and / or crosswise shrinkage of the goods is at least 10%, preferably 20 to 30%, based on the initial dimensions. Such a shrinkage results in a density which reduces the air and water permeability to such an extent that chemical treatment, for example in the form of a coating or impregnation, can even be dispensed with under certain circumstances.

Die Anwendung des Verfahrens ist besonders vorteilhaft bei der Herstellung von Webwaren, Maschenwaren und Tuftingwaren. Unter Webwaren sind insbesondere Segeltücher, Fallschirme und Inletts zu verstehen, welche für diesen Verwendungszweck eine optimale Luft- und Wasserdichtigkeit bzw. durchlässigkeit aufweisen müssen.The application of the method is particularly advantageous in the manufacture of woven goods, knitwear and tufted goods. Woven goods are to be understood in particular as sailcloths, parachutes and inlets, which must have optimum air and water tightness or permeability for this purpose.

Ein weiteres Anwendungsgebiet ist die Herstellung von verdichteten Polwaren, wo eine gute Verankerung der einzelnen Noppen eine grosse Rolle spielt.Another area of application is the production of compacted pile goods, where good anchoring of the individual knobs plays a major role.

Durch diesen Vorgang hat sich die Kettfadenzahl bei der Variante A um 32.5 %, bei der Variante B um 10 % erhöht.The fabric is washed without tension and in a shock-like manner at 70 to 98 ° C and then dyed and heat-set. This process has increased the number of warp threads in variant A by 32.5% and in variant B by 10%.

Die Polmaschenware wird möglichst spannungslos und schockartig bei 70 bis 98°C gewaschen und anschliessend gefärbt und thermofixiert.

Auf der Doppelplüschwebmaschine wird ein Gewebe hergestellt, das im Vergleich zu einem Referenzmuster identische Kett- und Schussfadenzahlen aufweist. Um den Schrumpfeffekt nicht vorzeitig auszulösen, darf das hochschrumpfende Kettgarn vor dem Webprozess keiner thermischen Vorbehandlung (z.B. Warmschlichten) ausgesetzt werden.A fabric is produced on the double plush hover that has identical warp and weft thread numbers compared to a reference pattern. In order not to trigger the shrinking effect prematurely, the shrinking warp yarn must not be exposed to any thermal pretreatment (e.g. warm sizing) before the weaving process.

Nach dem möglichst spannungslosen, schockartigen Eintauchen beim Waschvorgang bei 70 bis 98°C und anschliessendem Färben und Thermofixieren wird eine Polware erzielt, die aufgrund der Verdichtung des Grundgewebes eine gegenüber den Referenzmustern höhere Noppenhaftung aufweist. Ausserdem sind das Polstandvermögen und die Optik positiv beeinflusst worden.After the most stress-free, shock-like immersion during the washing process at 70 to 98 ° C and subsequent dyeing and heat-setting, a pile fabric is obtained which, due to the compression of the base fabric, has a higher knob adhesion compared to the reference samples. In addition, the pole position and the optics have been positively influenced.

Das erfindungsgemässe Verfahren hat den Vorteil, dass je nach den Bedingungen der stofftechnologischen und ausrüstungstechnischen Parameter der 30 bis 60 %ige Kochschrumpf der kaltverstreckten POY-Polyestergarne mehr oder weniger stark auf das Flächengebilde übertragen werden kann, d.h. es kann ein Warenschrumpf längs und/oder quer von 15 % und mehr, bezogen auf die Ausgangsdimension des Flächengebildes erzielt werden. Je lockerer die Rohgewebeeinstellung gewählt wird, um so höher ist der resultierende Warenschrumpf.The process according to the invention has the advantage that, depending on the conditions of the material and equipment parameters, the 30 to 60% boiling shrinkage of the cold-drawn POY polyester yarns can be transferred to the fabric to a greater or lesser extent, i.e. a shrinkage of length and / or lengthways of 15% and more, based on the starting dimension of the fabric, can be achieved. The looser the raw fabric setting is chosen, the higher the resulting shrinkage.

Durch das erfindungsgemässe Verfahren gelingt es auch wirtschaftlicher zu weben. Es kann bei einer tieferen Schussfadenzahl gewoben werden, wodurch ein besserer Weblauf erreicht und damit ein höherer Netzeffekt erzielt werden kann.The method according to the invention also makes weaving more economical. It can be woven with a lower number of weft threads, which results in better weaving and thus a higher network effect.
