Definitions
- the invention relates to an acoustically effective carpet molding for motor vehicles, in particular as a floor covering a passenger compartment, with a textile upper material which is connected via a multilayer material composite with a backing carpet, and a method for producing such a carpet molding.
- this object is achieved by a carpet molding with the material structure specified in claim 1 or by the method defined in claim 11.
- the carpet molding according to the invention has a textile upper material which is connected to a backing by a multi-layered composite material, wherein the material composite arranged between the upper material and the backing consists of a first needled nonwoven made of bicomponent melt fibers bonded to the outer material, a second needle felting thereafter is formed from Einkomponentenfasern and a subsequent third needled nonwoven bicomponent melt fibers.
- the two needled nonwoven webs formed from bicomponent fibers should each consist of at least 85% by volume bicomponent melt adhesive fibers.
- these needled webs are as complete as possible, i. as far as possible 100% of bicomponent melt-adhesive fibers.
- bicomponent fibers are used in an advantageous embodiment of the carpet molding according to the invention, the core of polyester and the sheath of polyester are formed with a melting point below the melting point of the core.
- Fig. 1 shows a preferred material structure of a carpet molding according to the invention
- FIGS. 2A and 2B process steps for producing a carpet molding according to the invention.
- Figures 3A, 3B and 3C process steps for producing a carpet molding according to the invention according to a variant.
- the carpet molding according to the invention can be used in particular as an acoustically effective floor covering in the passenger compartment of a motor vehicle. Other uses are the covering of the floor and the side panels of a trunk of a motor vehicle.
- the size of the carpet molding according to the invention preferably corresponds to the size of a vehicle floor to be covered, so that the vehicle floor can be completely covered with the one-piece carpet molding.
- the carpet molding can thus be relatively large, being adapted to all troughs and tunnel-like elevations of the vehicle floor.
- the carpet molding according to the invention consists of a textile upper 1, a first needle felt 2 of bicomponent melt adhesive fibers, a second needle felt 3 of monocomponent fibers, a third needle felt 4 of bicomponent Schmelzklebefasern- and optionally a back of carpet 5 (second back ) educated.
- the textile upper 1 preferably consists of a tufted product, wherein as a tuft carrier in particular a nonwoven of polyester and / or polypropylene fibers can be used.
- the pile material (pile material) of the textile upper 1 may be, for example, fibers, yarns or threads of polyamide, polyester or polypropylene and mixtures thereof, wherein the pile material may additionally also contain bicomponent fibers.
- the proportion of bicomponent fibers in the Optionally, the pile-forming fiber mixture is about 10% by volume.
- Tuftingware can be used as a textile upper material 1 if necessary, a dilute, a Malimoware, a Maliwattware, a knitted fabric or a nonwoven fabric.
- the first needle felt 2 immediately following the textile upper 1 is preferably made from 100% bicomponent fibers.
- the basis weight of the needle felt 2 is less than 200 g / m 2 ; for example, it is about 100 g / m 2 .
- the bicomponent fibers each have a sheath which has a much lower melting point than its core.
- the jacket material may for example consist of polypropylene and the core material of polyester.
- bicomponent fibers are used for the production of the erfindungs ⁇ contemporary carpet molding whose core material is made of polyester and the shell material of a modified, having a lower melting point polyester.
- the needle fleece 3 follows from Einkomponentenmaschinen.
- the monocomponent fibers may be man-made fibers and / or natural fibers. In turn, polyester fibers are preferred. But it can also be used as cotton fibers.
- the thickness and the weight per unit area of the needle-punched nonwoven 3 are considerably greater than in the case of the needle-punched nonwoven 2 made of bicomponent fibers.
- the needled nonwoven 3 has a basis weight in the range of 300 to 700 g / m 2 at a fiber fineness in the range of 3 to 7 dtex.
- the fiber length of the chemical or natural fibers of the needle felt 3 is in the range of, for example, 50 to 80 mm.
- carpet back (secondary backing) 5 a further needle felt or a heavy layer is finally arranged below the needle felt 4 of bicomponent fibers.
- the carpet backing 5 is comparatively thick or heavy. It has a basis weight in the range of 300 to 800 g / m 2 .
- the back of the carpet 5 is a heavy layer, for example of filler-containing elastomer, then this is not hot-stamped together with the other layers of material 1 to 4, but adapted in another way to the contour of the vehicle surface to be covered or the carpet molding and with the latter connected.
- the textile upper 1 is moistened with a suitable fluid, for example with water, before it with the other Material layers 2 to 4 or 2 to 5 is introduced as a loose stack in a device for hot stamping.
- a suitable fluid for example with water
- the moistening of the circuit board 1 can take place, for example, by means of a device 6 having a plurality of spray nozzles.
- a device 6 having a plurality of spray nozzles.
- By moistening excessive heating of the textile upper 1 is prevented during hot stamping. Excessive heating of the textile upper 1 may cause gloss effects that affect the appearance of the finished carpet molding.
- the moistening causes a steam effect, which protects the textile upper 1 during hot stamping from excessive heating. Due to the humidification, a reduction in the process time required for hot stamping (cycle time) is possible.
- the forming device has heatable forming tools 7, 8, the heating temperature of which is adjustable independently of one another.
- heating channels 9 for a heating fluid may be formed in the upper tool 7 and the lower tool 8.
- electrical heating resistors or the like can also be integrated in the molds 7, 8.
- the heating temperatures of the raised and lowered molds 7, 8 are depending on the nature of the textile upper 1 used, the melting temperature of the jacket material of the bicomponent fibers and the desired cycle time for the hot stamping in the range of 50 to 160 0 C.
- the molding tool 7 or 8 which faces the textile upper 1 is operated at a temperature which is at least 10 ° C. lower than the molding tool which forms the carpet back (needle felt) 5 or the needle felt 4 of the multilayer composite material (without heavy layer).
- the textile upper 1 facing mold is operated for example at a temperature below 100 0 C, while the temperature of the other mold is set to a temperature in the range of 110 to 160 0 C.
- the upper tool of the H discloses the upper tool of the H andmboge ⁇ device facing the textile upper 1.
- the production of the inventive carpet molding takes place in such a way that the lower tool of the hot stamping device faces the textile upper 1.
- infiltration of water or another moistening fluid from the moistened upper material 1 into the material layers 2 to 4 or 2 to 5 arranged thereunder can be prevented.
- the upper tool 7 and the lower tool 8 exchanged with each other or the figures 2B and 3C can be rotated in each case by 180 °, so that the molding material associated with the textile upper 1 is then the lower tool.

L'invention porte également sur la fabrication d'un tapis préformé de ce type. L'invention vise à créer un tapis préformé qui ne rétrécit pratiquement pas à la fabrication et présente une grande adaptation de forme. A cet effet, le matériau composite placé entre le matériau supérieur (1) et le dos (5) du tapis est constitué par un premier non-tissé aiguilleté (2) en fibre fusible bi-composante et relié au matériau supérieur, par un deuxième non-tissé aiguilleté (3) superposé en fibre monocomposante et par un troisième non-tissé aiguilleté (4) superposé en fibre fusible bi-composante. Pour réaliser ce tapis préformé, le matériau supérieur (1) textile est humidifié avant le thermoformage.
