Definitions
- the present invention relates to a method for obtaining a new kind of materials made up of a multilayer textile complex made from usable fibrous webs either as is, or as coating media or reinforcements for reinforcing laminated articles based on resin, waterproof coating consisting of support embedded in a bitumen composition. .
- non-woven / fabric complexes and / or combining tablecloths based on different materials for example a polyester nonwoven and a glass fiber veil.
- the needling operation makes it possible to implant the fibers of the tablecloths, in particular fibers of glass, across the entire thickness of the other layer for example of a polyester nonwoven, such so that the fibers of the first layer on which the action of the needles protrudes on each side the other layer which therefore serves as a support. Consequently, in the completed complex, the external faces are both made from fibers of the same kind.
- the fibers which provide the connection between the different layers are synthetic fibers re-oriented in the thickness direction of the complex multilayer, re-orientation being carried out in such a way so that it crosses the entire stack formed without however coming out on the outside of the layer to base of mineral fibers, so as not to alter the surface properties of the latter.
- the ends of the synthetic fibers thus implanted will come to bloom on the surface of the tablecloth based on mineral fibers.
- the material according to the invention can be consisting only of non-fibrous structures woven, of course, we could associate a weave internal reinforcement, such as a textile grid woven or non-woven, a sheet of foam, a felt, film or any combination of these.
- a weave internal reinforcement such as a textile grid woven or non-woven, a sheet of foam, a felt, film or any combination of these.
- the method according to the invention allowing obtaining such a complex, consists of superimposing at least two nonwoven fibrous webs, dry (carding in particular), one of these sheets being made up of staple fibers soft synthetics, not brittle, the other of staple fibers relatively mineral rigid and brittle, and it is characterized by the fact that the stack is subjected of tablecloths thus produced by the action of jets of fluids (air or water) acting on superimposed materials on the surface of the web based on synthetic fibers, so as to re-orient part of the fibers in the thickness direction, the stack being, during the action of the jets, supported by a continuous surface, permeable, preventing synthetic fibers from coming out outside the surface of the base web mineral fibers.
- any additional element such as for example a textile grid (woven or not), a fabric, a knitted fabric, a sheet of foam .., these elements being interposed alone or in combination with each other depending desired results and all layers being interconnected by synthetic fibers re-oriented in the thickness direction. It is obvious that these additional layers must be able to be crossed by the fluid jets.
- the new materials according to the invention have many advantages over to previous multilayer materials, by the fact that flexible synthetic fibers (polyester for example) that penetrate through the fiber-based web stiff (glass), allow to obtain a material unique composite of low thickness and devoid of any addition of glue, allowing many uses such as for example strengthening roofing membranes, laminated structures resin base ..
- connection between the layers avoids any risk of delamination, the fibrous hooks obtained by the penetration of the jets on the veil in synthetic fibers through the veil layer in mineral fibers, to obtain a composite glue-free laminate, facilitating the penetration of bitumen, resin ..
- the mineral fibers (glass) being arranged on one side of the complex, this allows to make finished products (for example coatings bituminous) meeting the specifications required for fire problems.
- connection to means of Jets allows to obtain a product of a great flexibility, impracticable by a connection of different layers in a conventional way, at using an adhesive.
- the fibers of this sheet which are closely linked to synthetic fiber (polyester), have advantageous strength properties at tensile strength, dimensional stability thermal, wear resistance, deterioration as it may be due to example with ultraviolet rays.
- Figure 1 illustrates in general, in edgy perspective, the material structure according to the invention which consists of fibrous sheets (1, 2) having different characteristics, these plies being linked together by entanglement of fibers (3) from one of the layers (1) through the second (2).
- one of the layers, (1) in this case is based on synthetic fibers flexible, not brittle while the other layer (2) is, for its part, based on mineral fibers relatively rigid and brittle, such as for example glass fibers, asbestos, carbon ..
- the overlapping tablecloths (1) and (2) are, in accordance with the invention, brought below the nozzles (6) by means of a conveyor belt (7) enabling them to be kept at flat during the intermingling operation.
- the tablecloth on which is exercised directly the fluid jets is the sheet (1) made up of synthetic fibers while the web (2) is, as to her, held on the support mat (7). Thanks to a such mode of implementation, under the action of the jets of fluid from the nozzles (6), part (3) of the fibers of the web (2) is re-oriented to penetrate inside the ply (2), the end (8) of said fibers thus re-oriented coming at most to flower the lower surface (5) of the ply (2) which is in contact with the support mat (7).
- the upper surface (4) of the sheet (1) has small perforations which are practically invisible given the made of the orientation of the fibers and which are distributed chance, this upper surface being of course made entirely of synthetic fibers, the surface (5) tablecloth based on mineral fibers retaining its original properties, by example its fire-resistant characteristics in the case where the fibers of the sheet (2) are glass-based.
- the material according to the invention can be consisting only of fibrous sheets thus bound between them, it is however preferable, in particular to communicate to the complex of characteristics mechanical tensile strength both in the long way that in the cross direction, to incorporate between the two layers (1, 2) an additional reinforcement (9) constituted for example by a textile grid (woven or no), a fabric, a knit. based on a material that can be either identical to one of the materials constituting the tablecloths (1, 2) is different.
- the structure of this additional reinforcement must be such that the fibers (3) of the ply (1) which are re-oriented can cross it under the action of the jets of fluid (6).
- the tablecloth (1) is located opposite fluid jets (6).
- the complex formed is preferably subjected to the action of means (10) (not shown in the figure 2) allowing it to be compressed and, in the case where the fluid jets are water jets, to moisten the tablecloths thus compressed.
- the pressure of the fluid jets will vary in depending on the thickness of the number of overlapping layers, this pressure being generally understood between 30 and 150 bars and, in this case, around of 70 bars.
- Such a material can be used in many applications and in particular as support coating, for example to make a reinforcement of bitumen chappe.
- Such a material is particularly suitable for be used as a bitumen support allowing to realize a single layer waterproofing coating so to obtain a coating having excellent characteristics dimensional stability, resistance to static and dynamic punching.
- the material described above can be easily stored and handled. Furthermore, the properties of each layer is preserved, which is particularly interesting when you want, for example get one side fire and the other side insulating. In addition, the intermingling operation causes obviously, channels inside the complex which promote the penetration of resins, bitumens, or any other material that we would like associate with such a complex.
- each of the tablecloths (1, 2) consisted of the same type of fibers, it could be envisaged to include in these tablecloths various additives or mix them with other fibers.
- various additives or mix them for example, we could incorporate inside the web based on thermoplastic fibers, hot-melt fibers whose properties could be revealed later, fibers capable of curling or revealing other properties, allowing better cohesion (bimetallic fibers for example).
