Definitions

  • the present invention relates to a method of making a velor carpet having advantageous properties over prior art velor carpets.
  • tufts or English “tufting” refers to a technique for producing three-dimensional textile surfaces. It is the most widely used process worldwide for the production of carpets.
  • Tufting works on the principle of a sewing machine. Needles bring the so-called pile yarn in a base material (fabric or nonwoven), the so-called backbone or carrier.
  • the needles pierce through the base material; before the needles run back again, the inserted pile yarn is held in place by grippers. This creates loops (tufts) on top of the tufting.
  • a "simpler" method which produces similar carpets without introduced from the outside in the first legs pile yarn.
  • For the velorization needles puncture a nonwoven / Malivlies and pull fiber loops between the bristles of a below the nonwoven / Malivlieses brush belt.
  • the fibers carried by the up and down movement of the needles are crossed and thereby solidified with each other.
  • the needles used may be needles which are laterally small barbs, so-called crown needles, or needles which have fork-like ends, so-called fork needles.
  • the velor is separated from the running brush belt by a pair of rollers.
  • the degree of compaction is determined by the number of stitches per unit area, the penetration depth of the needles into the nonwoven / Malivlies and the fiber fineness.
  • the fabric In the production of two-layer coverings (velor + wear layer), the fabric is turned after the first needle zone and needled in the second needle zone with the wear layer. Subsequently, a back-hardening of the fibers by means of binder based on synthetic rubber or acrylate based on different application methods. For latex-free incorporation, binder fibers or thermoplastic dispersions are used. The fiber thicknesses are between 6.7 and 17 dtex.
  • Tufted velor carpets usually have a higher fiber density. High fiber density, in turn, is considered to be an important quality feature of such velor carpets as it results in, among other things, better cleaning properties, increased resistance to compressive stress and better abrasion resistance.
  • JP 06 299453 A describes a method for producing a velor carpet, wherein a fleece is needled with a needle machine, then the fleece is separated from the tape before another fleece is placed on the back of the fleece.
  • DE 44 09 771 A1 describes a method for producing a velor needle felt.
  • an optionally pre-needled staple fiber fleece (12) is placed on a rotating, brush-like stitch backing (3) and then needle-punched under a pile formation on the stitch backing (3).
  • the staple fiber fleece (12) with the interposition of a layer with a higher tensile strength than the staple fiber fleece (12), in particular a spunbonded fabric (9), on the brush-like stitch substrate (3) is placed and then that when needling the pile fibers through the layer be pulled with the higher tensile strength.
  • EP 0 183 952 A1 describes a system for producing structured textile velor needle felt tracks. Specifically described is a system for producing structured velor velor felt textile webs from a pre-needled nonwoven made of staple fibers, consisting of a nonwoven laying machine, wherein at least the velor needle machine (15) with a, to be needled nonwoven (14) and serving as stitch backing, endless brush belt (21 ) which is composed of a plurality of bristle tufts (25) carrying brush plates (24) whose outer edges (26) are zigzag-shaped such that the edges (26) of each adjacent brush plates (24) intermesh in such a way the bristle tufts (25) have the same distances from one another along the outer edges (26) as the inner region of the brush plate (24), the bristles of the bristle tufts (25) are conically or wedge-shaped at their free end, the hold-down plate on the nonwoven web (14) and is depressed, and for the three-dimensional structuring of the pre-n
  • a conventional (single-layer) Dilour can increase with a higher puncture density, the pole density from a certain limit no more. This is prevented by two causes, namely the decrease in fiber mobility with increasing web densification and by the return effect by multiple detection of the same pile loops. According to the invention, the return effect is avoided by feeding the second web with a new supply of low density and highly mobile fibers.
  • Step a) is to be understood, on the one hand, that the pole / carrier fleece can be introduced into the brush belt (analogous to the tufting process). Alternatively and / or cumulatively but also the fibers of the nonwoven / Malivlieses can represent the Pol harsh; In this case, therefore, no separate pile yarn is introduced from the outside, but the fibers are drawn through the needles into the brush belt (analogously to the "simpler" method described above without pile yarn).
  • the fleece / Malivlies is separated after needling not only in step b) from the brush belt.
  • step c) additional fibers are also worked out by brushing from the nonwoven. This achieves a defined fiber level and the nonwoven retains its carrier layer.
  • the fiber density is thus 1.5 to 2 times higher for the same weights than standard velor carpets.
  • the use of binding fibers increases the fiber density even further.
  • steps b) and c) are carried out simultaneously. This corresponds in the sum of a saving of a process step and is therefore particularly favorable from a process-economical point of view.
  • step c) the rear side of the nonwoven is sprayed with water and / or a commercial dispersion or dried only by using binding fibers and, in particular, without tension.
  • the state of the fibers is fixed and the Fiber density increased again.
  • the fibers are incorporated.
  • step c) brushes the pile side of the nonwoven / Malivlieses for setting up the fibers against the grain, and shears protruding fibers. This additionally fixes the fibers once again and significantly smoothes the surface of the velor carpet, which is particularly important for applications in which the pile side is the visible side of the velor carpet.
  • a nonwoven / Malivlies and / or a pile yarn which comprises fibers of polypropylene (PP), polyester (PES), polyamide (PA) or mixtures thereof.
  • the particular advantage of the fibers and / or fiber mixtures lies in the price, in the light fastness and the abrasion value.
  • nonwoven / Malivlies and / or a Pol / carrier fleece whose / their fibers have a yarn count in a range of 3.3 to 11 dtex.
  • the particular advantage lies in the higher density at the same fiber weights, in the improved cleanability and in the increase of the abrasion values.
  • Fig. 1 the resting on the brush belt 3 Pol / carrier web 1 is first needled and compacted. A plurality of needles are attached to the needle bar 2. After this step, the needled nonwoven / Malivlies is separated by the roller brushes 4 of the brush belt - according to a simultaneous implementation of steps b) and c).
  • Fig. 2 is shown according to the invention, as the first uncompressed and resting on the brush belt 3 Pol / carrier fabric 1 is first compressed using the needle bar 2 and then needled with the additional pole / carrier fleece 9.
  • steps c) and d) also takes place in this case by the roller brushes 4th
  • Fig. 3 shows the back spraying the fleece with water and / or dispersion by means of the spray bar 5 or only use of binder fibers and a subsequent (tension) drying over the hanging loop 6, wherein the state of the fibers fixed, the fiber density is increased again and a simultaneous integration of the fibers takes place.
  • Fig. 4 shows a generally subsequent to the drying process step, in which the fixed fibers are placed with the other brush 7 against the first line. Subsequently, the nonwoven / Malivlies is passed over a shearing table and sheared fiber loops with the shear cylinder 8.
  • Fig. 5 shows an embodiment of the roller brushes 4th
  • Fig. 6 shows the schematically illustrated velor carpet 10, which is shown again in a macro shot 11, which is obtained by the inventive method.
  • Variant I and Variant II were prepared (hereinafter referred to as Variant I and Variant II, respectively - the latter was made using an additional pile / backing 9, as described in U.S. Pat Fig. 2 is shown prepared).
