Abstract

A laminate comprises: at least one nonwoven first layer, which comprises hybrid organic/inorganic fibres, said fibres containing a polysaccharide such as cellulose and silicic acid; and at least one nonwoven second layer which contains textile fibres obtained by devilling (shredding). The laminate according to the invention can be distinguished in that the second layer is of the type which is commercially available under the brand Flex-Xel from Fiberlok Inc. (USA).

Description

NON-WOVEN LAMINAATNON-WOVEN LAMINATE

De uitvinding ligt op het terrein van laminaten.The invention is in the field of laminates.

Een laminaat omvat ten minste twee feet elkaar verbonden lagen, die elk aan het laminaat een bepaalde eigenschap geven. Bijvoorbeeld kan een van de lagen een relatief grote mechanische sterkte bezitten en als dragerlaag dienst doen, terwijl de daarmee verbonden andere laag bijvoorbeeld makkelijk aanverfbaar is.A laminate comprises at least two feet of bonded layers, each of which gives the laminate a certain property. For example, one of the layers can have a relatively high mechanical strength and serve as a carrier layer, while the other layer associated therewith is easy to paint, for example.

Doel van de uitvinding is het verschaffen van een laminaat dat ten opzichte van bestaande laminaten een aanzienlijk verbeterde vlamdovendheid bezit, terwijl de produktiekosten niettemin gering zijn.The object of the invention is to provide a laminate which, compared to existing laminates, has a considerably improved flame retardancy, while the production costs are nevertheless low.

Daartoe verschaft de uitvinding een laminaat, omvattende: ten minste één non-woven eerste laag, die hybride organische/anorganische vezels omvat, welke vezels een poly-suiker, zoals cellulose en kiezelzuur bevatten; en ten minste één non-woven tweede laag, die door effilocheren verkregen textiele vezels bevat.To this end, the invention provides a laminate comprising: at least one non-woven first layer comprising hybrid organic / inorganic fibers, said fibers containing a poly-sugar such as cellulose and silica; and at least one nonwoven second layer containing textile fibers obtained by effilochation.

De gewenste mechanische en brandwerende eigenschappen worden door de toepassing bepaald. Gedacht kan bijvoorbeeld worden aan matrassen, waarvoor de tweede laag rechtstreeks aan de veren kan zijn aangebracht, meubels en de wanden van caravans, in welk laatste geval hoge eisen worden gesteld aan de mechanische sterkte en vlamdovendheid.The desired mechanical and fire-resistant properties are determined by the application. Examples include mattresses, for which the second layer can be applied directly to the springs, furniture and the walls of caravans, in which case high demands are made on the mechanical strength and flame retardancy.

Het laminaat volgens de uitvinding kan de bijzonderheid vertonen dat de tweede laag van het type is, dat in de handel verkrijgbaar is onder het merk Flex-Xel van Fiberlok Ine.The laminate according to the invention may have the special feature that the second layer is of the type commercially available under the brand Flex-Xel from Fiberlok Ine.

(USA).(USA).

Tevens kan het laminaat de bijzonderheid vertonen dat het bindmiddel uitgeharde droog-poederbindhars is van het type, dat in de handel verkrijgbaar is onder het merk Flex-Lok van Fiberlok Ine. (USA).The laminate may also have the special feature that the binder is cured dry powder binder resin of the type commercially available under the Flexlok brand from Fiberlok Ine. (USA).

In een specifieke uitvoering vertoont het laminaat de bijzonderheid dat de vezels van de eerste laag van het type zijn, dat in de handel verkrijgbaar is onder het merk Vizil van Kemira Fibres (Finland).In a specific embodiment, the laminate has the special feature that the fibers of the first layer are of the type commercially available under the brand Vizil from Kemira Fibers (Finland).

Veelal wenst men, zoals boven al aangegeven, een goede mechanische sterkte te combineren met een goede vlamdovendheid. Hiertoe kan het laminaat volgens de uitvinding bijvoorbeeld de bijzonderheid vertonen dat de tweede laag ten minste twee sublagen bevat, welke sublagen met elkaar zijn verbonden door middel van een kleeflaag, waarbij de naar de eerste laag gerichte sublaag een geringere dikte bezit dan de andere sublaag.As stated above, it is often desired to combine good mechanical strength with good flame retardancy. To this end, the laminate according to the invention may, for example, have the special feature that the second layer contains at least two sub-layers, which sub-layers are joined together by means of an adhesive layer, the sub-layer facing towards the first layer having a smaller thickness than the other sub-layer.

Zeer geschikt is die uitvoering gebleken, waarin de kleeflaag bestaat uit een materiaal op neopreenbasis.The embodiment in which the adhesive layer consists of a neoprene-based material has proved very suitable.

Een bepaalde uitvoering vertoont het kenmerk dat de eerste laag en de tweede laag aan elkaar gehecht zijn.A particular embodiment has the feature that the first layer and the second layer are bonded together.

Bijgaande tekening toont schematisch een dwarsdoorsnede door een willekeurig uitvoeringsvoorbeeld.The accompanying drawing schematically shows a cross-section through any exemplary embodiment.

Het laminaat volgens deze figuur heeft een dikte in de orde van grootte van 96 mm. Een eerste laag 1 is een doorgenaaide Vizil-laag zonder Flex-Lok hars met een oppervlaktedichtheid van 0,85 kg/m2. Over een hechtzone met Flex-Lok hars is de eerste laag 1 aan een sublaag 3 gehecht. Deze sublaag 3 maakt deel uit van de tweede laag 3, 4, 5 en bestaat uit Flex-Xel met een oppervlaktedichtheid van ongeveer 0,75 kg/m2 met een gehalte van 15% hars. De eerste sublaag 3 is aan een tweede sublaag 5 gehecht door middel van een dunne laag 4 Accrabond 723 neopreenrubberlijm. De tweede sublaag 5 bestaat uit Flex-Xel met een oppervlaktedichtheid van ongeveer 2,90 kg/m2 met een gehalte van 15% hars.The laminate of this figure has a thickness of the order of 96 mm. A first layer 1 is a tufted Vizil layer without Flex-Lok resin with a surface density of 0.85 kg / m2. The first layer 1 is bonded to a sublayer 3 over an adhesion zone with Flex-Lok resin. This sub-layer 3 is part of the second layer 3, 4, 5 and consists of Flex-Xel with a surface density of about 0.75 kg / m2 with a content of 15% resin. The first sublayer 3 is adhered to a second sublayer 5 by means of a thin layer 4 of Accrabond 723 neoprene rubber adhesive. The second sublayer 5 consists of Flex-Xel with a surface density of about 2.90 kg / m2 with a content of 15% resin.

De laag 1 bezit een dikte van ongeveer 6 mm, de laag 3 bezit een dikte vein ongeveer 15 mm en de laag 5 bezit een dikte van ongeveer 75 mm.The layer 1 has a thickness of about 6 mm, the layer 3 has a thickness of about 15 mm and the layer 5 has a thickness of about 75 mm.
