MOTOR VEHICLE FLOOR TRIM, LUGGAGE COMPARTMENT TRIM OR LOAD FLOOR TRIM WITH TEXTURED NEEDLE-PUNCHED CARPET SURFACE

Abstract

A method is disclosed for producing a three-dimensionally deformable velour carpet for a floor trim, luggage compartment trim or load floor trim for motor vehicles, the carpet surface of which has a needled structure on the visible side, as well as the trim itself.

Claims

1. A method for the production of a three-dimensionally deformable velour carpet for a floor trim, a luggage compartment trim or a load floor trim of a motor vehicle with a structurally needled, deformation-resistant surface having a grammage of the carpet in the range from 180 g/m.sup.2 to 700 g/m.sup.2, which is characterized in that at a defined setting of the penetration depth of the needles as well as a defined setting of their penetration density, a velour carpet is produced from an initial nonwoven, wherein a brush band is used which has, segmentally or partially, sections of different brushes and/or brush arrangements or brushes of different bristle heights, two or more needle types of different lengths are arranged segmentally across the width of a needle board, and this velour carpet is added and deformed with one or more sublayers.

2. The method according to claim 1, characterized in that, the structuring of the bristles is effected by arrangement of brush segments, by different brush heights and/or by defined placement and/or removal of bristles in the band and/or dividing webs.

3. The method according to claim 1, characterized in that needles are used which differ in length, fineness, fork opening and fork orientation.

4. A three-dimensionally shaped velour carpet for a floor trim, a luggage compartment trim or a load floor trim of a motor vehicle with a structurally needled, deformation-resistant surface with a grammage of the carpet in the range from 180 g/m.sup.2 to 700 g/m.sup.2, further comprising one or more sublayers, wherein the visible side of the carpet has a three-dimensional structurally needled, durable surface consisting of 3D ornaments/carpet patterns over length and width which differ in height (pile height).

Description

EXAMPLE OF EXECUTION

[0037] For the production of a deformation-resistant/stable, structure-needled floor trim, a pre-fleece made of a fiber mix consisting of 80% commercially available 13 dtex fibers, fiber length 60 mm, PET fiber and 20% commercially available 6.7 dtex fibers, fiber length 64 mm, PET fiber was used as the initial nonwoven. The weight per unit area was 480 g/m.sup.2.

[0038] Fork needles of different lengths from Groz-Beckert KG 15×16×20×40×73.0 D G 9077/616751 [length: 74.8 mm] and 15×17×32×40×74.8 D G 9077/615921 [length: 76.6 mm] have been installed in a needle board of the velours IV (8000 n/lm), alternately in 20 cm wide strips. The zero adjustment of the machine was matched to the longer of the two needles.

[0039] Ornaments/patterns were worked into the brushes of the brush band by shortening the brush fibres.

[0040] During production, it was important to find the optimum penetration depth and the optimum penetration density by testing the machine settings.

[0041] In the case of the velour carpet shown in FIG. 1 and FIG. 2, the stitch density was 600 stitches/cm.sup.2, and the stitch depth 3 mm.

[0042] FIG. 3 shows a two-ply velour carpet (beige and black pre-fleece). Here the stitch density was 600 stitches/cm.sup.2, and the stitch depth 7 mm.
