Definitions
- the invention relates to a thermally stable enamel-bonded spunbond made of load-bearing Filaments and serving as enamel binders Binder filaments in which the difference of Melting points of load-bearing and binding filaments is less than 30 ° C.
- DE-C-14 35 114 is a nonwoven fabric known that contains crimped fibers or threads and that by means of a thermoplastic binder or thermoplastic binding fibers Heating is solidified.
- the melting point of the binding fibers should be at least 20 ° C below the Melting point of the supporting filaments. Due to the proportion of crimped fibers in This nonwoven fabric is very drapable, i.e. he creases like a woven fabric; but it is as highly resilient and dimensionally stable reinforcement material and not usable as a tufted carrier.
- Highly resilient spunbonded nonwovens bonded with melt binders are known, for example, from DE-PS 22 40 437 and DE-A-36 42 089. These previously known spunbonded nonwovens, in which both the supporting filaments and the binder filaments can consist of polyesters, serve in particular as reinforcing and carrier materials in the manufacture of needled felt and tufting.
- filaments of a relatively coarse individual titer of more than 8 dtex are used.
- the proportion of binder filaments is 10 to 30%, preferably between 15 and 25%.
- individual titres of 5 or 12 dtex are given in the examples; the proportion of binder filaments is between 10 and 50%. preferably between 15 and 30%.
- the weight per unit area is stated to be greater than 120 g / m 2 .
- DE-PS 22 40 437 emphasizes that a relatively large distance between the Melting point of the supporting filaments and the the binder filaments must be observed, the minimum Must be 30 ° C. This is to ensure that when the nonwoven solidifies, a thermal damage to the supporting filaments is excluded.
- This instruction is in a more recent publication, DE-OS 36 42 089 further tightened: there the difference of Melting points of load bearing and binder filaments even be at least 90 ° C. That's why there are polyolefin filaments as binder filaments prefers.
- melt-bonded spunbonded nonwoven made of supporting polyester filaments and binder filaments is known, the melting point of the latter binder filaments being 10 ° C. below the melting point of the supporting polyester filaments.
- the disclosed melt-bond-strengthened spunbonded fabrics have a weight per unit area of 50 to 100 g / m 2 .
- the present invention now relates to a melt-bond-bonded nonwoven fabric with high strength and high dimensional stability, which is thermally highly resilient, ie which has an extremely advantageous high processing and use temperature.
- the melt-bond-strengthened spunbonded web consists of load-bearing filaments and binder filaments serving as melt binders, and is characterized in that the melting point of the binder filaments is less than 30 ° C., preferably less than 20 ° C., below the melting point of the load-bearing filaments, with the exception of such spunbonded webs whose basis weight is between 50 and 100 g / m 2 .
- the supporting filaments and binder filaments are preferably made of polyester.
- the basis weight of the spunbonded nonwovens according to the invention is generally in the range between 50 and 500 g / m 2 , preferably between 50 and 250 g / m 2 , but can of course also be selected to be lower or higher for special applications, with the result that such spunbonded nonwovens are excluded from their basis weight is between 50 and 100 g / m 2 .
- the individual titer of the supporting filaments and binder filaments is preferably in the range between 1 and 20 dtex and the proportion of the binder filaments is preferably between 5 and 25 percent by weight.
- Spunbonded fabrics according to the invention are preferred in which the individual titer of the binder filaments is smaller than that of the supporting filaments.
- Those spunbonded webs according to the invention in which the melting point of the binder filaments is 10 to 20 ° C. below the melting point of the supporting filaments are particularly preferred.
- the spunbonded fabrics according to the invention consist of load-bearing filaments made of polyethylene terephthalate, during the melt binder from a polymer exists, whose melting point is the above Difference to the melting point of the supporting filaments having.
- the binder filaments preferably consist from an isophthalic acid modified Polyester with a correspondingly slightly lowered Melting point.
- the proportion of binder filaments in the total weight of the spunbonded nonwovens according to the invention is chosen to be as low as possible within the range given above and is adapted to the intended use of the nonwovens. Lower binder proportions further improve the thermal and mechanical properties, while higher binder proportions result in particularly delamination-resistant nonwovens.
- the weight per unit area of the nonwovens according to the invention and the individual titer of the filaments are chosen within the ranges specified above depending on the area of use. For example, a basis weight of up to 500 g / m 2 and a single titer of up to 20 dtex are expediently chosen for a tufting carrier.
- the supporting filaments and binder filaments consist of flame-retardant modified polyesters.
- a further preferred embodiment of the nonwovens according to the invention has a layer structure of supporting filaments and binder filaments, it being particularly advantageous if the two outer layers do not contain any binder filaments.
- spunbonded nonwovens according to the invention are preferred, the binder filaments of which contain an antistatic, in particular carbon black.
- a further special embodiment of the nonwovens according to the invention does not contain separate binder filaments but bicomponent filaments in a core-shell or side-by-side arrangement, which are made up of the two polymers for the load-bearing and the binding filaments in the desired ratio.
- the spun-bonded nonwoven formed according to the invention is free from resinous binders and is therefore inherently flame-retardant.
- the low flammability can be further improved by suitable selection of flame-retardant modified raw materials for the supporting filaments and the binder filaments.
- These flame-retardant spunbonded fabrics can then also be used in rooms at risk of fire, e.g. B. as a carrier material for curtains, wallpaper, blinds, or as components for seat covers in vehicles or aircraft.
- Particularly voluminous spunbonded fabrics according to the invention are also preferred, such as those using a rel. small proportion of binder filaments and sieve drum fixation can be obtained. These then also have a loose, fibrous surface structure, which significantly increases the adhesion of coating materials, PVC or bitumen. Such voluminous spunbonded nonwovens with a fiber-rich surface are also suitable for the production of filter fabrics.
- the addition of antistatic agents, in the simplest case of soot, in the melting cylinder also permits the use of the spun-bonded nonwoven according to the invention in potentially explosive zones or as a filter medium for clean rooms.
- the dyeability of the melt binder can be adapted to that of the supporting filaments by modifying the melt binder raw material; on the other hand, different dyeability can also be used to create interesting color effects.
- the spunbonded nonwoven according to the invention is produced in a manner known per se by depositing load-bearing filaments and binder filaments on a moving screen base to form a tangled nonwoven, and is characterized in that binder filaments are deposited whose melting point is less than 30 ° C., preferably less than 20 ° C. , is below the melting point of the supporting filaments.
- Load-bearing filaments and binder filaments which consist of polyester, are preferably deposited.
- the amount of filaments deposited per m 2 is measured according to the criteria given above; as a rule, 50 to 500 g of filaments are deposited per m 2 .
- Filament is preferably deposited using a rotating baffle plate and a downstream guide surface as described in DE-PS 27 13 241.
- the filament is deposited by a plurality of rows of depositing elements, one behind the other in the direction of movement of the screen support, from which alternating load-bearing and binding filaments are deposited.
- the polymers for the supporting filaments and the binder filaments are spun out and deposited as bicomponent filaments in the specified ratio.
- the needles are not needled Filaments, just thermal pre-consolidation, as for example in DE-PS 33 22 936 is described, and an adjoining final thermal solidification, e.g. with smooth or profiled roller.
- basis weights may result in needling a further improvement in the nonwoven properties to lead.
- the thermal consolidation is particularly preferably carried out by hot air, for example in screen drum fixers, which can be followed by a pair of embossing rollers.
- Particularly voluminous spunbonded nonwovens result from the lowest possible proportion of binder filaments and a sieve drum fixation.

Description
Das erfindungsgemäße schmelzbinderverfestigte Spinnviies besteht aus tragenden Filamenten und als Schmelzbinder dienenden Binderfilamenten, und ist dadurch gekennzeichnet, daß der Schmelzpunkt der Binderfilamente weniger als 30°C, vorzugsweise weniger als 20°C, unter dem Schmelzpunkt der tragenden Filamente liegt, wobei solche Spinnvliese ausgenommen sind deren Flächengewicht zwischen 50 und 100 g/m2 liegt.
Die tragenden Filamente und Binderfilamente bestehen vorzugsweise aus Polyester. Das Flächengewicht der erfindungsgemäßen Spinnvliese liegt in der Regel im Bereich zwischen 50 und 500 g/m2, vorzugsweise zwischen 50 und 250 g/m2, kann aber natürlich für spezielle Anwendungen auch geringer oder höher gewählt werden, wobei solche Spinnvliese ausgenommen sind deren Flächengewicht zwischen 50 und 100 g/m2 liegt. Der Einzeltiter der tragenden Filamente und Binderfilamente liegt vorzugsweise im Bereich wischen 1 und 20 dtex und der Anteil der Binderfilamente vorzugsweise zwischen 5 und 25 Gewichtsprozent.
Bevorzugt sind erfindungsgemäße Spinnvliese, in denen der Einzeltiter der Binderfilamente kleiner ist als der der tragenden Filamente.
Bevorzugt sind insbesondere auch solche erfindungsgemäßen Spinnvliese, bei denen der Schmelzpunkt der Binderfilamente 10 bis 20°C unter dem Schmelzpunkt der tragenden Filamente liegt.
Das Flächengewicht der erfindungsgemäße Vliese und der Einzeltiter der Filamente wird innerhalb der oben angegebenen Bereiche je nach dem Einsatzgebiet gewählt. Beispielsweise wird für einen Tuftingträger zweckmäßigerweise ein Flächengewicht bis zu 500 g/m2 und ein Einzeltiter bis zu 20 dtex gewählt.
Als besonders zweckmäßig hat es sich erwiesen, die Art der Einbringung der Binderfilamente und ihren Anteil auf das ausgewählte Flächengewicht abzustimmen.
Weiterhin sind solche erfindungsgemäßen Spinnvliese bevorzugt, in denen die tragenden Filamente und Binderfilamente aus flammhemmend modifizierten Polyestern bestehen.
Eine weitere bevorzugte Ausführungsform der erfindungsgemäßen Vliese weist eine Schichtstruktur aus tragenden Filamenten und Binderfilamenten auf, wobei es besonders vorteilhaft ist, wenn die beiden äußeren Schichten keine Binderfilamente enthalten. Für spezielle Anwendungen, bei denen es auf eine möglichst gute elektrische Leitfähigkeit der Vliesstoffe ankommt, sind erfindungsgemäße Spinnvliese bevorzugt, deren Binderfilamente ein Antistatikum, insbesondere Ruß, enthaiten.
Eine weitere spezielle Ausführungsform der erfindungsgemäßen Vliese enthält keine gesonderten Binderfilamente sondern Bikomponentenfilamente in Kern-Hülle- oder Seite-an-Seite-Anordnung, die aus den beiden Polymeren für die tragenden und die bindenden Filamente in dem gewünschten Mengenverhältnis aufgebaut sind.
Das erfindungsgemäß ausgebildete Spinnvlies ist frei von harzigen Bindemitteln und daher von Haus aus schwer entflammbar. Wie bereits erwähnt, kann die Schwerentflammbarkeit durch geeignete Auswahl von flammhemmend modifizierten Rohstoffen für die tragenden Filamente und die Binderfilamente noch verbessert werden. Diese flammfesten Spinnvliese können dann auch in brandgefährdeten Räumen eingesetzt werden, z. B. als Trägermaterial für Vorhänge, Tapeten, Jalousien, oder als Bestandteile für Sitzbezüge in Fahrzeugen oder Flugzeugen. Bevorzugt sind auch besonders voluminöse erfindungsgemäße Spinnvliese, wie sie z.B. unter Einsatz eines rel. geringen Anteils von Binderfilamenten und Siebtrommelfixierung erhalten werden. Diese haben dann auch eine lockere, faserige Oberflächenstruktur, die die Haftung von Beschichtungsmaterialien, von PVC oder Bitumen deutlich erhöht. Derartige voluminöse Spinnvliese mit faserreicher Oberfläche eignen sich auch zur Herstellung von Filterstoffen. Der Zusatz von Antistatika, im einfachsten Fall von Ruß, im Schmelzzylinder erlaubt darüberhinaus den Einsatz des erfindungsgemäß ausgebildeten Spinnvlieses in explosionsgefährdeten Zonen oder auch als Filtermedium für Reinräume.
Die Anfärbbarkeit des Schmelzbinders kann an die der tragenden Filamente durch Modifikation des Schmelzbinder-Rohstoffes angepaßt werden; andererseits kann eine unterschiedliche Anfärbbarkeit auch zu interessanten Farbeffekten genutzt werden.
Vorzugsweise werden tragende Filamente und Binderfilamente abgelegt, die aus Polyester bestehen. Weiterhin ist es bevorzugt, den Einzeltiter der tragenden Filamente und Binderfilamente im Bereich zwischen 1 und 20 dtex und/oder den Anteil der Binderfilamente zwischen 5 und 25 Gewichtsprozent zu wählen. Die Menge der pro m2 abgelegten Filamente wird nach den oben angegebenen Kriterien bemessen;in der Regel werden 50 bis 500 g Filamente pro m2 abgelegt.
Zur Herstellung erfindungsgemäßer Spinnvliese mit der bevorzugten Schichtenstruktur erfolgt die Filamentablage durch mehrere in Bewegungsrichtung der Siebunterlage hintereinander liegende Reinen von Ablageorganen, aus denen abwechselnd tragende und bindende Filamente abgelegt werden.
In einer speziellen Ausführungsform werden die Polymere für die tragenden Filamente und die Binderfilamente in dem angegebenen Mengenverhältnis als Bikomponentenfilamente ausgesponnen und abgelegt.
Besonders voluminöse Spinnvliese ergeben sich bei einem möglichst geringen Anteil von Binderfilamenten und einer Siebtrommelfixierung.
