Definitions
- the present invention relates to a cleaning textile, comprising a three-dimensional warp-knitted fabric with a first and a second knitted surface, the first and second knitted surfaces being connected by means of pile threads, the pile threads penetrating the first and second knitted surfaces, in particular for use in clean rooms and rooms with high hygiene standards.
- the EP 321 6 902 A1 discloses a reusable cleaning textile with a 3D warp-knitted fabric with a first and second knitted surface, the first and second knitted surfaces being connected by means of connecting threads, the first knitted surface having microfibers and scraping fibers with a titre>1 dtex and the connecting threads comprising monofilament threads and microfibers.
- the first and second knitted surfaces are designed differently, in particular with regard to their fiber composition and/or their stitch pattern.
- the DE 198 39 505 A1 discloses a cleaning textile with a 3D warp knitted fabric, having a first and second knitted surface, the first and second knitted surface being connected by means of pile weaves of different lengths, which penetrate the first and second knitted surfaces and are lamellar in design, the first knitted surface consisting of a monofilament and microfiber is knitted.
- microfibers have an abrasive effect on the surface to be cleaned due to their structure or due to the dirt particles they absorb, which can lead to surface damage during cleaning, which often takes place very frequently in clean rooms. This damage can appear in the form of small ridges between which the risk of dirt accumulation is increased compared to the otherwise flat surface. Due to their fineness, the risk of microfibers being separated from the cleaning textile is also higher, so that contamination of the surface to be cleaned by the separated microfibers is not at all unlikely.
- the present invention therefore sets itself the task of specifying a cleaning textile made from a large number of filaments, which do not belong to the microfiber sector, with a strength that is particularly suitable for cleaning, which at the same time has good water absorption, water release and water storage capacity.
- a cleaning textile comprising a three-dimensional warp-knitted fabric with a first and a second knitted surface, the first and second knitted surface each having at least two thread systems, with a thread system of the first knitted surface has a thread count of at least 100 dtex and at least 90 filaments and a thread system of the second knitted surface has a thread count of at least 70 dtex and at least 20 filaments, the first and second knitted surface being connected by means of pile threads, the pile threads penetrating the first and second knitted surfaces are formed, wherein filaments of at least one thread system of the first knitted surface have a tetralobal cross section.
- the cleaning textile is preferably knitted on a double Raschel machine, the cleaning textile being a knitted fabric.
- the cleaning textile according to the invention is manufactured using a double-Raschel technique, by means of which three-dimensional spacer fabrics of 1 mm to 70 mm, in particular 1.5 mm to 10 mm, can be produced.
- An offset movement and an oscillating movement of guide bars aligned orthogonally to this are provided for stitch formation.
- the guide bars move the threads arranged in eyelet needles around latch needles, with the latch needles performing up and down movements orthogonal to the movements mentioned above.
- Thread systems with filaments with a tetralobal cross-section are particularly well suited according to the invention because, due to their large circumferential surface, they can both loosen stubborn dirt from a surface without requiring the user to overcome tiring frictional forces over the long term, as well as high have the capacity to absorb cleaning liquids.
- the scouring forces that can be applied to a cleaning surface by thread systems with filaments with a tetralobal cross-section are such that even strongly adhering dirt can be removed.
- Thread systems with filaments with a tetralobal cross-section have a thread count of at least 100 dtex.
- the pile threads provided according to the invention lead in a particularly advantageous manner to a dimensionally stable intermediate layer between the first and second knitted surface, which is particularly well suited for absorbing and storing cleaning liquid.
- cleaning fluid When in use, cleaning fluid constantly escapes from the internal reservoir of cleaning fluid generated in this way through the first knitted surface facing the surface to be cleaned, so that a uniform cleaning quality is ensured.
- a dosing of the cleaning agent discharge is realized according to the invention via the mesh density of the knitted surface bindings.
- the pile threads penetrate the knitted fabric surfaces, so that the cleaning liquid can be guided evenly along the pile threads.
- the filaments of at least some of the pile threads have a tetralobal cross section, so that the strength of the cleaning textile is increased in order to maintain its three-dimensional structure and thus also its function after repeated cleaning operations and preparations.
- Forming the pile threads, preferably all pile threads, with filaments having a tetralobal cross-section advantageously makes additional fastening means superfluous. This is advantageous in terms of production technology and is cost-effective, since the cleaning textile can be produced using a double Raschel knitting machine, in particular in just one production step.
- the pile threads with filaments with a tetralobal cross-section have a thread count of at least 100 dtex and at least 90 filaments.
- the pile threads are formed with the same thread system as the first knitted surface, which significantly reduces the complexity of the cleaning textile and simplifies its manufacture.
- the first and second knitted surface each have a large number of wales per unit area, with at least one wale per unit area having additional material to the other wales.
- the mixture of materials made possible in this way in the first knitted surface which is in contact with the surface to be cleaned when in use advantageously causes both high absorption of the cleaning liquid by materials with a smaller titer and optimal rigidity of the materials with a larger titer.
- the ratio between the different materials can be adapted as required to the surface to be cleaned and its degree of soiling.
- the use of different materials does not have any influence on the structure of the first knitted surface per se.
- the first knitted surface has antistatically treated threads.
- the discharge of electric current through the cleaning textile is particularly advantageous for protection against high-energy charge concentrations, as can occur in the chemical, pharmaceutical and medical sectors.
- they are treated using coating methods, in particular using wet methods or plasma application methods.
- the first knitted surface has fewer stitches per unit area than the second knitted surface in order to ensure good liquid conduction to the pile threads and optimal exit of the cleaning liquid.
- the knitted surfaces can be formed together by means of a production process and in particular in a single production step, which considerably reduces the complexity and costs of production.
- the structure of the first knitted surface is selected such that it successively releases the stored water.
- the structure of the second knitted surface facing away from the surface to be cleaned when in use is designed in such a way that the dimensional stability and mechanical strength of the cleaning textile according to the invention is increased.
- the first knitted surface has a more open-pored structure than the second knitted surface.
- the cleaning textile is heat-treated according to the invention after its production, so that the structure and dimensions of the cleaning textile are retained even after several cycles of use and possible stresses that have arisen in previous production steps are reduced.
- the heat treatment can be carried out with hot water, steam or dry heat. Since such a heat treatment is used in particular with synthetic textiles, the cleaning textile according to the invention is made from synthetic materials, in particular from polyester. According to the invention, the temperature for the heat treatment is around 180°C. The low temperature advantageously protects the material while at the same time developing the advantages mentioned.
- the filaments of some pile threads have a round cross-section and that the pile threads with filaments with a round cross-section consist of one filament, so that a mixture of pile threads with filaments with a tetralobal cross-section and those with a round cross-section from one filament result, with preferably the pile threads with tetralobal filaments predominate with a proportion of the number of at least 80%, in particular clearly predominate with a proportion of the number of at least 90%, preferably very greatly predominate (>99%).
- the pile threads made from a filament with a round cross-section have a thread count, in particular a filament count of at least 50 dtex.
- the cleaning textile 1 shows a sectional view of a cleaning textile 1 according to the invention, wherein its first knitted surface 2 is shown facing towards a surface 6 to be cleaned.
- the cleaning textile 1 according to the invention extends from the first knitted surface 2 via an inner space 7 to a second knitted surface 3.
- the first and second knitted surface 2, 3 have essentially the same thickness.
- the interior 7 is enclosed by the first and second knitted surface 2, 3 and is thus formed by them.
- the cleaning textile 1 has a smaller thickness than in its central region 9.
- a large number of pile threads 4 arranged essentially parallel to one another and perpendicular to the two knitted surfaces 2, 3 and, when in use, also to the surface 6, pass through the first and second knitted surface 2, 3 and the interior 7. Accordingly, the pile threads 4 contribute to the strength and liquid absorbency of the cleaning textile 1.
- the first knitted surface 2 has openings 11, which are decisive for dispensing cleaning liquid and are also suitable for receiving it.
- the second knitted surface 3 has fastening means 10 for fastening the cleaning textile 1 to a cleaning unit (not shown), in particular a mop holder.
- the fasteners 10 - usually receiving pockets for wings of the mop holder - are connected to the second knitted surface 3 in the edge area 8 in order not to influence the structure and characteristics of the cleaning textile 1 within the central area 9 by possible seams for fixing the fasteners 10.
- the invention with its three-dimensional structure and the use of filaments with a tetralobal cross-section, enables both a large absorption and storage volume, high absorbency and high rigidity to maintain your shape, without the use of microfibers.

Description
Die vorliegende Erfindung betrifft ein Reinigungstextil, aufweisend ein dreidimensionales Kettengewirk mit einer ersten und einer zweiten Gewirkfläche, wobei die ersten und zweiten Gewirkflächen mittels Polfäden verbunden sind, wobei die Polfäden die ersten und zweiten Gewirkflächen durchsetzend sind, insbesondere zur Verwendung in Reinräumen und Räumen mit hohen Hygienestandards.The present invention relates to a cleaning textile, comprising a three-dimensional warp-knitted fabric with a first and a second knitted surface, the first and second knitted surfaces being connected by means of pile threads, the pile threads penetrating the first and second knitted surfaces, in particular for use in clean rooms and rooms with high hygiene standards.
Zur Flächenreinigung insbesondere bei der gewerblichen Reinigung auch von klinischen, pharmazeutischen und anderen Reinräumen ist es erforderlich, den dortigen hohen Anforderungen während und nach abgeschlossener Reinigung gerecht zu werden. Hierbei werden oft Reinigungstextilien mit unterschiedlichen Fasercharakteristiken genutzt, um das Reinigungstextil zum einen mit einer hohen Saugfähigkeit auszustatten und um zum anderen eine hohe Abrasion der auf den zu reinigenden Oberflächen anhaftenden Verschmutzungen zu erreichen. Bei dieser Flächenreinigung werden neben Einweg-Produkten auch Mehrwegprodukte eingesetzt, die nach einem Reinigungsvorgang zum Wiedereinsatz aufbereitet werden und daher bestimmten Festigkeitsanforderungen zu entsprechen haben.For surface cleaning, especially in the commercial cleaning of clinical, pharmaceutical and other clean rooms, it is necessary to meet the high requirements there during and after the cleaning has been completed. Cleaning textiles with different fiber characteristics are often used in order to provide the cleaning textile with high absorbency and to achieve high abrasion of the dirt adhering to the surfaces to be cleaned. In this type of surface cleaning, reusable products are used in addition to disposable products, which are prepared for reuse after a cleaning process and therefore have to meet certain strength requirements.
Die
Die
Nachteilig an diesem Stand der Technik ist, dass Mikrofasern auf Grund ihrer Struktur an sich oder durch die von ihnen aufgenommenen Schmutzpartikel auf die zu reinigende Oberfläche abrasiv wirken, was bei der in Reinräumen oftmals sehr häufig erfolgenden Reinigung zu einer Oberflächenbeschädigung führen kann. Diese Beschädigung kann in Form von kleinen Graten auftreten, zwischen denen das Risiko einer Schmutzansammlung im Vergleich zu der sonstigen, ebenen Oberfläche erhöht ist. Aufgrund ihrer Feinheit ist auch das Risiko einer Abtrennung von Mikrofasern aus dem Reinigungstextil höher, so dass eine Verschmutzung der zu reinigenden Oberfläche durch die abgetrennten Mikrofasern durchaus nicht unwahrscheinlich ist.A disadvantage of this prior art is that microfibers have an abrasive effect on the surface to be cleaned due to their structure or due to the dirt particles they absorb, which can lead to surface damage during cleaning, which often takes place very frequently in clean rooms. This damage can appear in the form of small ridges between which the risk of dirt accumulation is increased compared to the otherwise flat surface. Due to their fineness, the risk of microfibers being separated from the cleaning textile is also higher, so that contamination of the surface to be cleaned by the separated microfibers is not at all unlikely.
Die vorliegende Erfindung stellt sich daher die Aufgabe, ein Reinigungstextil aus einer Vielzahl an Filamenten, welche nicht dem Mikrofaserbereich zuzuordnen sind, mit einer zur Reinigung besonders geeigneten Festigkeit anzugeben, das gleichzeitig eine gute Wasseraufnahme-, Wasserabgabe- und Wasserspeicherfähigkeit aufweist.The present invention therefore sets itself the task of specifying a cleaning textile made from a large number of filaments, which do not belong to the microfiber sector, with a strength that is particularly suitable for cleaning, which at the same time has good water absorption, water release and water storage capacity.
Diese Aufgabe wird gelöst durch ein Reinigungstextil, aufweisend ein dreidimensionales Kettengewirk mit einer ersten und einer zweiten Gewirkfläche, wobei die erste und zweite Gewirkfläche jeweils mindestens zwei Fadensysteme aufweisen, wobei ein Fadensystem der ersten Gewirkfläche eine Fadenfeinheit von mindestens 100 dtex und mindestens 90 Filamente aufweist und ein Fadensystem der zweiten Gewirkfläche eine Fadenfeinheit von mindestens 70 dtex und mindestens 20 Filamente aufweist, wobei die erste und zweite Gewirkfläche mittels Polfäden verbunden sind, wobei die Polfäden die ersten und zweiten Gewirkflächen durchsetzend ausgebildet sind, wobei Filamente mindestens eines Fadensystems der ersten Gewirkfläche einen tetralobalen Querschnitt aufweisen.This object is achieved by a cleaning textile comprising a three-dimensional warp-knitted fabric with a first and a second knitted surface, the first and second knitted surface each having at least two thread systems, with a thread system of the first knitted surface has a thread count of at least 100 dtex and at least 90 filaments and a thread system of the second knitted surface has a thread count of at least 70 dtex and at least 20 filaments, the first and second knitted surface being connected by means of pile threads, the pile threads penetrating the first and second knitted surfaces are formed, wherein filaments of at least one thread system of the first knitted surface have a tetralobal cross section.
Vorzugsweise ist das Reinigungstextil auf einer Doppelraschelmaschine gewirkt, wobei das Reinigungstextil eine Maschenware ist. In besonders vorteilhafter Weise ist das erfindungsgemäße Reinigungstextil mittels einer Doppelrascheltechnik gefertigt, mittels welcher dreidimensionale Abstandsgewirke von 1 mm bis 70 mm, insbesondere 1,5 mm bis 10 mm herstellbar sind. Zur Maschenbildung sind eine Versatzbewegung sowie eine, zu dieser orthogonal ausgerichtete, Schwingbewegung von Legebarren vorgesehen. Die Legbarren bewegen die in Lochnadeln angeordneten Fäden um Zungennadeln herum, wobei die Zungennadeln, analog zu den zuvor genannten Bewegungen, zu diesen orthogonale Auf- und Ab-Bewegungen ausführen.The cleaning textile is preferably knitted on a double Raschel machine, the cleaning textile being a knitted fabric. In a particularly advantageous manner, the cleaning textile according to the invention is manufactured using a double-Raschel technique, by means of which three-dimensional spacer fabrics of 1 mm to 70 mm, in particular 1.5 mm to 10 mm, can be produced. An offset movement and an oscillating movement of guide bars aligned orthogonally to this are provided for stitch formation. The guide bars move the threads arranged in eyelet needles around latch needles, with the latch needles performing up and down movements orthogonal to the movements mentioned above.
Fadensysteme mit Filamenten mit tetralobalem Querschnitt sind erfindungsgemäß besonders gut geeignet, da sie auf Grund ihrer großen Umfangsfläche sowohl stark anhaftenden Schmutz von einer Oberfläche lösen können, ohne dabei für einen Nutzer auf Dauer nur in ermüdender Weise überwindbare Reibungskräfte erforderlich zu machen, als auch eine hohe Aufnahmefähigkeit für Reinigungsflüssigkeiten aufweisen. Die durch Fadensysteme mit Filamenten mit tetralobalem Querschnitt auf eine Reinigungsfläche aufbringbaren Scheuerkräfte sind derart, dass auch stark anhaftender Schmutz entfernbar ist. Erfindungsgemäß weisen die Fadensysteme mit Filamenten mit tetralobalem Querschnitt eine Fadenfeinheit von mindestens 100 dtex auf.Thread systems with filaments with a tetralobal cross-section are particularly well suited according to the invention because, due to their large circumferential surface, they can both loosen stubborn dirt from a surface without requiring the user to overcome tiring frictional forces over the long term, as well as high have the capacity to absorb cleaning liquids. The scouring forces that can be applied to a cleaning surface by thread systems with filaments with a tetralobal cross-section are such that even strongly adhering dirt can be removed. According to the invention Thread systems with filaments with a tetralobal cross-section have a thread count of at least 100 dtex.
Die erfindungsgemäß vorgesehenen Polfäden führen in besonders vorteilhafter Weise zu einer dimensionsstabilen Zwischenlage zwischen erster und zweiter Gewirkfläche, die zur Aufnahme und Speicherung von Reinigungsflüssigkeit besonders gut geeignet ist.The pile threads provided according to the invention lead in a particularly advantageous manner to a dimensionally stable intermediate layer between the first and second knitted surface, which is particularly well suited for absorbing and storing cleaning liquid.
Aus dem so erzeugten internen Reservoir an Reinigungsflüssigkeit tritt im Benutzungsfall stetig Reinigungsflüssigkeit durch die zur zu reinigenden Oberfläche weisenden ersten Gewirkfläche, so dass eine gleichmäßige Reinigungsqualität gewährleistet ist.When in use, cleaning fluid constantly escapes from the internal reservoir of cleaning fluid generated in this way through the first knitted surface facing the surface to be cleaned, so that a uniform cleaning quality is ensured.
Eine Dosierung des Reinigungsmittelaustritts ist dabei erfindungsgemäß über Maschendichte der Gewirkflächenbindungen realisiert.A dosing of the cleaning agent discharge is realized according to the invention via the mesh density of the knitted surface bindings.
Besonders vorteilhaft durchsetzen die Polfäden die Gewirkflächen, sodass eine gleichmäßige Leitung der Reinigungsflüssigkeit entlang der Polfäden ermöglicht ist.In a particularly advantageous manner, the pile threads penetrate the knitted fabric surfaces, so that the cleaning liquid can be guided evenly along the pile threads.
In Ausgestaltung der Erfindung ist vorgesehen, dass die Filamente wenigstens einiger der Polfäden einen tetralobalen Querschnitt aufweisen, sodass die Festigkeit des Reinigungstextils gesteigert ist, um seine dreidimensionale Struktur und damit auch seine Funktion nach wiederholten Reinigungseinsätzen und Aufbereitungen zu erhalten. Die Ausbildung der Polfäden, vorzugsweise aller Polfäden, mit Filamenten mit einem tetralobalen Querschnitt macht mit Vorteil zusätzliche Befestigungsmittel überflüssig. Dies ist fertigungstechnisch vorteilhaft und kostengünstig, da das Reinigungstextil mittels einer Doppelraschelwirkmaschine, insbesondere in nur einem Fertigungsschritt, herstellbar ist. Mit großem Vorteil weisen die Polfäden mit Filamenten mit tetralobalem Querschnitt eine Fadenfeinheit von mindestens 100 dtex und mindestens 90 Filamenten auf. Eine derart hohe Filamentzahl verleiht dem Reinigungstextil eine höhere Zugfestigkeit und Flexibilität, was die Langlebigkeit des Reinigungstextils erhöht. Die bei der Nutzung und Aufbereitung des Reinigungstextils auftretenden hohen Zug- und Scherkräfte sind so problemlos ableitbar. Insbesondere sind die Polfäden mit demselben Fadensystem wie die erste Gewirkfläche ausgebildet, was die Komplexität des Reinigungstextils deutlich mindert und dessen Herstellung vereinfacht.In an embodiment of the invention it is provided that the filaments of at least some of the pile threads have a tetralobal cross section, so that the strength of the cleaning textile is increased in order to maintain its three-dimensional structure and thus also its function after repeated cleaning operations and preparations. Forming the pile threads, preferably all pile threads, with filaments having a tetralobal cross-section advantageously makes additional fastening means superfluous. This is advantageous in terms of production technology and is cost-effective, since the cleaning textile can be produced using a double Raschel knitting machine, in particular in just one production step. With great advantage, the pile threads with filaments with a tetralobal cross-section have a thread count of at least 100 dtex and at least 90 filaments. Such a high number of filaments gives the cleaning textile greater tensile strength and flexibility Longevity of the cleaning textile increased. The high tensile and shearing forces that occur when using and preparing the cleaning textile can thus be derived without any problems. In particular, the pile threads are formed with the same thread system as the first knitted surface, which significantly reduces the complexity of the cleaning textile and simplifies its manufacture.
In Weiterbildung der Erfindung ist vorgesehen, dass die erste und zweite Gewirkfläche jeweils eine Vielzahl an Maschenstäbchen je Flächeneinheit aufweisen, wobei mindestens ein Maschenstäbchen je Flächeneinheit ein zu den übrigen Maschenstäbchen zusätzliches Material aufweist. Das auf diese Weise ermöglichte Materialgemisch der ersten, im Benutzungsfall an der zu reinigenden Oberfläche anliegenden, Gewirkfläche bewirkt mit Vorteil sowohl eine hohe Aufnahme der Reinigungsflüssigkeit durch Materialien mit kleinerem Titer und einer optimalen Steifigkeit der Materialien mit größerem Titer.In a development of the invention, it is provided that the first and second knitted surface each have a large number of wales per unit area, with at least one wale per unit area having additional material to the other wales. The mixture of materials made possible in this way in the first knitted surface which is in contact with the surface to be cleaned when in use advantageously causes both high absorption of the cleaning liquid by materials with a smaller titer and optimal rigidity of the materials with a larger titer.
Das Verhältnis zwischen den verschiedenen Materialien ist erfindungsgemäß je nach Bedarf auf die zu reinigende Oberfläche und deren Verschmutzungsgrad anpassbar. Hierbei ist erfindungsgemäß jedoch vorgesehen, dass die Verwendung verschiedener Materialien keinen Einfluss auf die Struktur der ersten Gewirkfläche an sich ausübt.According to the invention, the ratio between the different materials can be adapted as required to the surface to be cleaned and its degree of soiling. However, it is provided according to the invention that the use of different materials does not have any influence on the structure of the first knitted surface per se.
In Weiterbildung der Erfindung weist die erste Gewirkfläche antistatisch behandelte Fäden auf. Das Ableiten elektrischen Stroms durch das Reinigungstextil ist besonders zum Schutz vor hochenergetischen Ladungskonzentrationen, wie sie im Chemie-, Pharma- und Medizinbereich vorkommen können von Vorteil. Um eine antistatische Charakteristik der Fäden zu erhalten, werden diese mittels Beschichtungsverfahren, insbesondere mittels Nassverfahren oder Plasmaaufbringungsverfahren behandelt.In a development of the invention, the first knitted surface has antistatically treated threads. The discharge of electric current through the cleaning textile is particularly advantageous for protection against high-energy charge concentrations, as can occur in the chemical, pharmaceutical and medical sectors. In order to obtain an antistatic characteristic of the threads, they are treated using coating methods, in particular using wet methods or plasma application methods.
In Ausgestaltung der Erfindung weist die erste Gewirkfläche weniger Maschen pro Flächeneinheit als die zweite Gewirkfläche auf, um eine gute Flüssigkeitsleitung zu den Polfäden und einen optimalen Austritt der Reinigungsflüssigkeit zu gewährleisten. Die Gewirkflächen sind mittels eines Fertigungsverfahrens und insbesondere in einem einzigen Fertigungsschritt gemeinsam ausbildbar, was Komplexität und Kosten der Herstellung erheblich mindert. Ebenfalls erfindungsgemäß ist die Struktur der ersten Gewirkfläche so gewählt, dass sie das gespeicherte Wasser sukzessive abgebend ist. Die Struktur der im Benutzungsfall von der zu reinigenden Oberfläche abgewandten, zweiten Gewirkfläche ist hingegen so ausgebildet, dass die Dimensionsstabilität und mechanische Festigkeit des erfindungsgemäßen Reinigungstextils erhöht ist. Insbesondere weist die erste Gewirkfläche eine offenporigere Struktur als die zweite Gewirkfläche auf.In an embodiment of the invention, the first knitted surface has fewer stitches per unit area than the second knitted surface in order to ensure good liquid conduction to the pile threads and optimal exit of the cleaning liquid. The knitted surfaces can be formed together by means of a production process and in particular in a single production step, which considerably reduces the complexity and costs of production. Likewise according to the invention, the structure of the first knitted surface is selected such that it successively releases the stored water. On the other hand, the structure of the second knitted surface facing away from the surface to be cleaned when in use is designed in such a way that the dimensional stability and mechanical strength of the cleaning textile according to the invention is increased. In particular, the first knitted surface has a more open-pored structure than the second knitted surface.
In besonders vorteilhafter Weise ist das Reinigungstextil nach seiner Herstellung erfindungsgemäß wärmebehandelt, sodass eine Aufrechterhaltung der Struktur und der Dimensionierung des Reinigungstextils auch nach mehreren Verwendungszyklen gegeben ist und mögliche, in vorhergehenden Herstellungsschritten entstandene, Spannungen vermindert sind. Die Wärmebehandlung kann erfindungsgemäß mit Heißwasser, Wasserdampf oder Trockenhitze erfolgen. Da eine derartige Wärmebehandlung insbesondere bei synthetischen Textilien Verwendung findet, ist das erfindungsgemäße Reinigungstextil aus synthetischen Materialien, insbesondere aus Polyester gefertigt. Die Temperatur zur Wärmebehandlung liegt erfindungsgemäß bei rund 180°C. Die geringe Temperatur schont in vorteilhafterweise das Material bei gleichzeitiger Ausbildung der genannten Vorteile.In a particularly advantageous manner, the cleaning textile is heat-treated according to the invention after its production, so that the structure and dimensions of the cleaning textile are retained even after several cycles of use and possible stresses that have arisen in previous production steps are reduced. According to the invention, the heat treatment can be carried out with hot water, steam or dry heat. Since such a heat treatment is used in particular with synthetic textiles, the cleaning textile according to the invention is made from synthetic materials, in particular from polyester. According to the invention, the temperature for the heat treatment is around 180°C. The low temperature advantageously protects the material while at the same time developing the advantages mentioned.
Schließlich ist noch vorgesehen, dass Filamente einiger Polfäden einen runden Querschnitt aufweisen und die Polfäden mit Filamenten mit rundem Querschnitt aus einem Filament bestehen, so dass sich ein Gemisch von Polfäden mit Filamenten mit tetralobalem Querschnitt und von solchen mit rundem Querschnitt aus einem Filament ergeben, wobei vorzugsweise die Polfäden mit tetralobalen Filamenten mit einem Anteil der Anzahl von mindestens 80 % überwiegen, insbesondere mit einem Anteil der Anzahl von mindestens 90% deutlich überwiegen, bevorzugt sehr stark überwiegen (> 99%). Die Polfäden aus einem Filament mit rundem Querschnitt weisen eine Fadenfeinheit, insbesondere eine Filamentfeinheit, von mindestens 50 dtex auf.Finally, it is also provided that the filaments of some pile threads have a round cross-section and that the pile threads with filaments with a round cross-section consist of one filament, so that a mixture of pile threads with filaments with a tetralobal cross-section and those with a round cross-section from one filament result, with preferably the pile threads with tetralobal filaments predominate with a proportion of the number of at least 80%, in particular clearly predominate with a proportion of the number of at least 90%, preferably very greatly predominate (>99%). The pile threads made from a filament with a round cross-section have a thread count, in particular a filament count of at least 50 dtex.
