Abstract

In a method for raising textile fabrics, such as jeans fabrics, garments produced therefrom, or the like, by washing the fabric in a washing machine with water in the presence of a scouring (abrading, scrubbing) material, it is proposed to avoid the use of non-reuseable materials by using foam glass media as the scouring material.

Description

Die Erfindung betrifft ein Verfahren zum Aufrauhen von textilen Geweben, wie Jeans-Stoffen, daraus hergestellten Kleidungsstücken oder dergleichen, wobei das Gewebe in einer Waschmaschine mit Wasser unter Zusatz eines granulierten Scheuerstoffes gewaschen wird.The invention relates to a method for roughening textile fabrics, such as jeans fabrics, articles of clothing or the like made therefrom, the fabrics being washed in a washing machine with water with the addition of a granular abrasive.

Zur Erzeugung eines in der Bekleidungsbranche mit "stone-washed" umschriebenen Erscheinungsbildes von Kleidungsstücken, insbesondere solchen aus Jeans-Stoffen, werden diese einer Nachbehandlung unterzogen, bei der der üblicherweise verwendete Indigo-Farbstoff zum Teil wieder ausgewaschen und das Textilgewebe angerauht wird.In order to produce a "stone-washed" appearance of garments in the clothing industry, in particular those made of denim fabrics, these are subjected to an aftertreatment in which the indigo dye which is usually used is partially washed out again and the textile fabric is roughened.

Bei einem bekannten Verfahren werden die zu behandelnden Kleidungsstücke mit Wasser gewaschen, dem als Scheuerstoff ein gewisser Anteil an Bimskies mit einer Korngröße von etwa 20 bis 50 mm zugesetzt wird. Der Waschvorgang wird beispielsweise in Lochblech-Waschtrommeln durchgeführt. Während des Waschvorganges scheuern die Bimsstücke an der Gewebeoberfläche und rauhen diese auf. Als Folge davon verliert das Gewebe seine Steifigkeit und seine einheitlich blaue, glatte Oberfläche. Das Gewebe wird je nach Behandlungsdauer weicher und flauschiger. Durch den Scheuereffekt der Bimsstücke wird zusätzlich zum Auswascheffekt des Wassers die Indigo-Färbung mehr oder weniger stark von der Gewebeoberfläche entfernt. An Nähten und Säumen der Kleidungsstücke tritt dieser Effekt naturgemäß verstärkt auf.In a known method, the items of clothing to be treated are washed with water, to which a certain proportion of pumice gravel with a grain size of approximately 20 to 50 mm is added as an abrasive. The washing process is carried out, for example, in perforated sheet washing drums. During the washing process, the pumice pieces scrub and roughen the fabric surface. As a result, the fabric loses its stiffness and its uniform blue, smooth surface. Depending on the duration of treatment, the tissue becomes softer and fluffier. The abrasion effect of the pumice pieces, in addition to the washout effect of the water, removes the indigo dye more or less from the fabric surface. This effect naturally occurs increasingly at the seams and hems of the garments.

Die Bimsstücke sind während des Waschvorganges vor allem durch die gegenseitige Reibung einem ständigen Verschleiß unterworfen, so daß deren Korngröße stetig abnimmt. Am Ende des Waschvorganges sind die Bimsstücke so Klein, daß sie durch die Lochbleche der Waschtrommel mit dem Waschwasser ausgetragen werden. Der verbrauchte Bims mit Korngrößen von z.B. kleiner als 10 mm wird vom Waschwasser abgetrennt.The pumice pieces are subject to constant wear and tear during the washing process, above all due to the mutual friction, so that their grain size steadily decreases. At the end of the washing process, the pumice pieces are so small that they are discharged with the washing water through the perforated plates of the washing drum. The used pumice with grain sizes of e.g. less than 10 mm is separated from the wash water.

Das bekannte Verfahren hat nun den Nachteil, daß sich der in erheblichen Mengen angefallene verbrauchte Bims unter wirtschaftlich vertretbarem Aufwand nicht wiederverwerten läßt.The known method now has the disadvantage that the pumice that is used up in considerable quantities cannot be recycled at economically justifiable expense.

Ausgehend von der geschilderten Problematik liegt der Erfindung die Aufgabe zugrunde, ein Verfahren vorzuschlagen, bei dem ein wiederverwertbarer Stoff anstelle von Bims verwendet wird.Based on the problems described, the object of the invention is to propose a method in which a recyclable material is used instead of pumice.

Die Lösung dieser Aufgabe ist im Kennzeichnungsteil des Anspruches 1 angegeben und besteht darin, daß als Scheuerstoff Schaumglas-Körper verwendet werden. Dabei haben sich Schaumglas-Bruchstücke mit im wesentlichen kantiger oder kubischer Form bewährt (Anspruch 7). Die beim Waschvorgang in einer Lochblech-Waschtrommel durch Abnutzung auf eine Korngröße kleiner als der Lochdurchmesser der Lochblech-Waschtrommel reduzierten Schaumglas-Körper können dabei abgesondert und für die Schaumglas-Herstellung wiederverwendet werden (Anspruch 2).The solution to this problem is specified in the characterizing part of claim 1 and consists in that foam glass bodies are used as the scouring agent. Foam glass fragments with an essentially angular or cubic shape have proven themselves (claim 7). The foam glass body reduced to a grain size smaller than the hole diameter of the perforated plate washing drum during the washing process in a perforated plate washing drum can be separated and reused for the production of foam glass (claim 2).

Das nach dem Waschvorgang anfallende Schaumglas mit Korngrößen z.B. unterhalb von 10 mm kann also problemlos einem Wiederverwertungskreislauf zugeführt werden und beispielsweise zusammen mit Recycling-Flaschenglas zu den Schaumglas-Körpern der geforderten Korngröße verarbeitet werden.The foam glass with grain sizes obtained after the washing process e.g. Below 10 mm, a recycling circuit can be easily fed and processed, for example, together with recycling bottle glass to the foam glass bodies of the required grain size.

Dabei ist im übrigen von Vorteil, daß Schaumglas in der Regel überwiegend geschlossenporig ist. Insofern lagern sich in erster Linie nur an der Oberfläche der Granulatkörper störende Zusatzstoffe aus dem Waschwasser ab. Folglich sind die ausgesonderten Schaumglas-Körper gegenüber den ausgesonderten Bimsstücken in weitaus geringerem Maße verseucht. Dementsprechend ist die Wiederverwertung zusätzlich erheblich vereinfacht, wobei festzuhalten ist, daß die an den Schaumglas-Körpern anhaftenden Zusatzstoffe beim nachfolgenden Herstellungsprozeß für das Schaumglas in der Regel ausgebrannt und damit unschädlich gemacht werden. Es entfällt also einer besonderer Reinigungsschritt für die Entfernung der Schadstoffe von den Schaumglas-Körpern.It is also advantageous that foam glass is usually mostly closed-pore. In this respect, additives from the wash water are primarily deposited on the surface of the granules. As a result, the separated foam glass bodies are contaminated to a much lesser extent than the separated pumice pieces. Accordingly, recycling is considerably simplified, it should be noted that the additives adhering to the foam glass bodies are generally burned out in the subsequent manufacturing process for the foam glass and are thus rendered harmless. There is therefore no special cleaning step for removing the pollutants from the foam glass bodies.

Ein weiterer Vorteil der Verwendung von Schaumglas als Scheuerstoff liegt darin, daß die Kleidungsstücke im Vergleich zu bimsgewaschenen sich weicher und flauschiger anfühlen. Darüber hinaus werden durch die Verwendung von Schaumglas die Waschzyklen je nach Stoffart um 10 bis 30% verkürzt. Dadurch werden die Energiekosten der Waschanlagen gesenkt und deren Ausnutzungsgrad gesteigert.Another advantage of using foam glass as an abrasive is that the garments feel softer and fluffier than pumice-washed ones. In addition, the use of foam glass shortens the washing cycles by 10 to 30% depending on the type of fabric. As a result, the energy costs of the washing systems are reduced and their degree of utilization increased.

Eine vorteilhafte Korngröße für die Schaumglas-Körper beträgt etwa 20 bis 50 mm (Anspruch 3).An advantageous grain size for the foam glass body is about 20 to 50 mm (claim 3).

Da das zur Verwendung kommende Schaumglas nahezu vollständig aus Altglas (Recycling-Glas) besteht, ist das erfindungsgemäße Verfahren auch vorteilhafterweise in den Glas-Wiederverwertungskreislauf einzubinden.Since the foam glass used is made almost entirely of waste glass (recycling glass), the method according to the invention can also advantageously be integrated into the glass recycling cycle.

Gute Waschergebnisse wurden mit einem Schaumglas-Granulat erzielt, das ein Schüttgewicht von etwa 120 bis 300 kg/m³ aufweist (Anspruch 5).Good washing results have been achieved with a foam glass granulate which has a bulk density of about 120 to 300 kg / m³ (claim 5).

Nach Anspruch 6 können beim Waschvorgang dem Waschwasser Zusätze zum Bleichen, Imprägnieren und/oder Weichmachen des Gewebes zugesetzt werden.According to claim 6, additives for bleaching, impregnating and / or softening the fabric can be added to the wash water during the washing process.

Ein Ausführungsbeispiel für das erfindungsgemäße Verfahren wird nachfolgend kurz erläutert:
In einer Lochblech-Waschtrommel mit einem Lochdurchmesser von 10 mm und mit einem Volumen von etwa 4 m³ wird eine Füllung Jeans-Hosen mit einem Trockengewicht von 200 kg unter Zusatz von 300 kg Schaumglas-Körpern mit Wasser einer Temperatur von ca.80°C während einer Zeitdauer von ca.60 min gewaschen. Die Schaumglas-Körper sind handelsübliche Bruchstücke mit einer Korngröße von 20 bis 50 mm und einem Schüttgewicht von 200 kg/m³. Die Herstellung solcher Schaumglas-Körper ist z.B. in der DE 30 44 130 C2 bzw. EP 0 170 978 B1 bzw. EP 0 292 424 B1 beschrieben. Nach diesem vorstehend beschriebenen Waschvorgang zeigen die Jeans-Hosen das typische "stone-washed"-Erscheinungsbild und fühlen sich sehr weich und flauschig an.An exemplary embodiment of the method according to the invention is briefly explained below:
In a perforated sheet washing drum with a hole diameter of 10 mm and a volume of about 4 m³, a filling of jeans trousers with a dry weight of 200 kg with the addition of 300 kg foam glass bodies with water at a temperature of about 80 ° C during washed for a period of about 60 min. The foam glass bodies are commercially available fragments with a grain size of 20 to 50 mm and a bulk density of 200 kg / m³. The production of such foam glass bodies is described, for example, in DE 30 44 130 C2 or EP 0 170 978 B1 or EP 0 292 424 B1. After this washing process described above, the jeans pants show the typical "stone-washed" appearance and feel very soft and fluffy.
