Definitions

  • the invention relates to a method for producing a multilayer, non-woven, textile fabric according to the preamble of claim 1 and a multilayer, non-woven, textile fabric according to the preamble of claim 10.
  • Such a known method and the generic fabric are known from DE-A-2,452,136.
  • a carrier layer which is smooth, closed or open pile loops in the initial state
  • a loop pile layer which is structured or patterned in the finished product, which the usage surface forms, in which fibers from the underlayer are at least partially needled through this backing layer from the rear surface of the backing layer, individual fibers from the underlayer are needled into free spaces, filling them completely, a tufted, extremely low pile weight loop pile layer of the fabric.
  • the patterning options are limited to the properties of needled, openly projecting individual fibers, which, as is desired there, give the loop pile layer the appearance of a tip-sheared article or an open-pole article with a uniform structure.
  • the invention is therefore based on the object of creating a generic production method for a textile fabric of the type mentioned at the outset, which allows any or targeted supplementing of the loop pile layer with fiber material and with which a textile fabric is to be obtained which has any patterns and / or structures can have.
  • the lower layer consists of spherical to worm-shaped fiber structures made of spherically entangled fibers or contains such, whereby at least some of these spherical to worm-shaped fiber structures are needled through the carrier layer, changing their original shape, in such a way that their spherical head part is in extend the loop pile layer forming the surface of use.
  • spherical to worm-shaped fiber structures made of spherically entangled fibers and threads are known, which are generally referred to there as spherical yarns.
  • these ball yarns are connected to one another or to a carrier layer in that individual holding fibers are removed from the ball yarns and introduced into other ball yarns or in the carrier layer (actively needling) or that holding fibers removed from the carrier layer are introduced into these ball yarns (passive needled).
  • the spherical to worm-shaped fiber structures can be needled in any way into the loop pile layer through the carrier layer, as a result of which a particularly simple method can be used for the production.
  • the fact that the spherical to worm-shaped fiber structures pass through the carrier layer depends on the nature, such as the density of the fiber structures and the type of fiber, so that they can be easily damaged or destroyed by the carrier layer, e.g. B. through openings in the same, pushed through or can be forced through.
  • the fiber structures therefore advantageously have a high density of the fibers in them.
  • Ball yarns with a density of the fibers or threads of 0.3 to 1 g / cm 2 can be present.
  • the fiber structures can be needled to the top of the loop pile layer or beyond it. But you can also only in the loop pile layer z. B. in their free spaces, needled and present between the loops of a tufted pile yarn, from which the loop pile layer can be made.
  • the pile yarn can have open or closed pile loops. Depending on its design, the loop pile layer can already contain the free spaces; but it can also only when the fiber structures are introduced into the loop pile layer, e.g. B. rooms with displacement of
  • the pile-containing loop pile layer can be tufted by pile yarn, rustling or knitting, i. H. be made by methods that have poles or loops, e.g. B. pile loops or velor-like surfaces, and what is to be understood below also means the pile-containing, tufted loop pile layer.
  • the spherical to worm-like fiber structures can be needled in such a way that they are, for. B. have remained with a part in the lower layer and / or the carrier layer and are anchored there.
  • the fiber structures through the carrier layer changes their shape compared to the remaining in the lower layer fiber structures, so that the fiber structures in the loop pile layer have a shape that differs from that as it was originally in the lower layer.
  • the fiber structures can still remain anchored in the lower layer and / or the carrier layer with a tail or with a tuft of fibers. If spherical to worm-shaped fiber structures are needled from the lower layer into the loop pile layer, the spherical shape can be changed as it is forced through the carrier layer in such a way that a z. B. pear-shaped fiber structure is present, which remains with its tapered part in the carrier layer and / or the lower layer.
  • a loop pile layer can be achieved in which, in addition to pile yarn, a fiber material of a different shape is present in the form of the spherical to worm-shaped fiber structures. This enables a variety of patterning and structuring possibilities to be achieved, in particular if the fiber structures needled through have a different color than the tufted poles, or are themselves of a different color. Essentially all of the fiber structures in the lower layer or only a few can be needled through the carrier layer, so that different possibilities for patterning and / or structuring can also result from this.
  • the product has already been tufted with the pile pile layer containing the poles and the fiber structures can be introduced into it.
  • the pile-containing loop pile layer by tufting a pile yarn in the carrier layer, for. B. in a base fabric or a fiber composite, and then in particular immediately afterwards to apply the fiber structures to the carrier layer and then to needle through the same.
  • the fiber structures are preferably placed unconnected on the carrier layer and then needled.
  • the fiber structures can contain natural and / or synthetic fibers or threads, such as multifilaments or spun yarns.
  • the tufted loop pile layer can have a pile weight of 100 to 1500 g / M 2 , preferably 300 to 600 g / m 2 , and there can be 20,000 to 120,000, preferably 30,000 to 90,000 pile loops / m 2 .
  • the fiber structures can be needled with a needling density which is preferably greater than the number of pile loops / M 2 and thus the pile layer in the loop pile layer and can be 5 to 50 punctures / c M 2 .
  • the fiber structures can have a thickness in at least one direction of their expansion, which is at least 1 mm.
  • the ball yarns can have a thickness of 1 to 25 mm. If necessary, the underlayer can advantageously serve as the usual backing layer for the fabric. You can after needling the fiber structures in the usual way by a binder, for. B. latex, solidified.
  • the textile fabric according to the invention can be a floor or wall covering material or a decorative fabric. It can be a tufted loop pile carpet made of e.g. B. Continuous filaments are present as the pile yarn, in which the fiber structures can be present in the aforementioned shape or form between the pile loops.
  • the fiber structures can also protrude above the pile loops so that a high-low structure can be achieved. Patterns can be created by patterning the fiber structures, e.g.
  • the spherical to worm-shaped fiber structures can be specified.
  • patterns can also be achieved by loose tufting, ie the pile yarn loops can be introduced into the carrier layer with low density or with low weight and the fiber structures in the loop pile layer, e.g. B. by filling in of free spaces, then create a pattern.
  • Such options for patterning are described in EP publication 0.055.362, which is why reference is made to the same at this point for a more detailed explanation.
  • the pile yarn loops can also be introduced into the carrier layer in the form of a pattern and the free spaces created by the pattern can be filled by the fiber structures.
  • the fiber structures can be present in the underlayer alone or else mixed with fiber material of another shape.
  • a z. B. uniform structure of multifilaments as the pile yarn through the needled, spherical to worm-like fiber structures z. B. be converted into a product with a pimpled character, which can have the appearance of a very expensive manufactured carded yarn.
  • a z. B. uniform structure of multifilaments as the pile yarn through the needled, spherical to worm-like fiber structures z. B. be converted into a product with a pimpled character, which can have the appearance of a very expensive manufactured carded yarn.
  • smooth pile yarns such. B. flame or other effects.
  • This is known, for. B. achievable with expensive spun pimpled yarns, which, however, can lead to disruptive production interruptions when tufting due to tearing off the pimples.
  • the subsequent introduction of the fiber structures can be assumed to be a smooth, tufted pile yarn, which can be tufted less prone to failure due to the lack of knobs.
  • a smooth tufted product can subsequently be structured or patterned in the desired manner, e.g. B. provided with knobs, which may be in the form of the fiber structure. Due to the fiber structure, the pile loops can also be adequately supported and protected against twisting. The pole loops can be bent horizontally or essentially horizontally instead of vertically. This can cause additional patterns. Spherical to worm-shaped fiber structures mixed with thread pieces can also be present in the lower layer, so that after vernadein in the loop pile layer, a mixture of spherical worm-shaped fiber structures and thread pieces can be present. This allows further patterning options to be achieved.
  • the needling of the flat structures can be carried out on conventional needling machines and with conventional needling needles, which allow the spherical to worm-shaped fiber structures to be gripped, such as, for. B. felting needles or barbed needles.
  • Figures 1 and 2 each show a multilayer, non-woven, textile fabric in a schematic representation in section.
  • a pile yarn 2 is tufted into a carrier layer 3, so that the same pile loops protrude from the upper side 3 'and thus a pile pile layer 4 containing poles is present.
  • the spherical to worm-shaped fiber structures 5 contain spherically entangled fibers, as z. B.
  • the spherical to worm-shaped fiber structures 5 When it is forced through the carrier layer 3, the spherical to worm-shaped fiber structures 5 become more or less slimmer than their original shape in the lower layer 6 and therefore their shape is changed. However, after passing through the carrier layer 3, they can expand again more or less, so that the spherical to worm-shaped fiber structures 5 are present in the loop pile layer 4 with a spherical head part 5 'which essentially corresponds to their original shape. As a result of the squeezing, a narrower, e.g. B.
  • the narrower part 5 can also consist of only a few fibers of the spherical to worm-shaped fiber structures 5, so that the spherical to worm-shaped fiber structures 5 in the loop pile layer 4 have essentially the same original shape 5 and can be referred to as such.
  • the spherical to worm-shaped fiber structures 5 with their part 5 can only remain in the carrier layer 3 and be anchored there.
  • the lower layer 6 is depleted on them. so that there are fewer spherical to worm-shaped fiber structures 5 than before needling through, but depending on the needling, which is done by simply inserting needles into the underlayer 6 from the rear, all or essentially all of the original ones can be found in the underlayer 6 be spherical to worm-shaped fiber structures 5 into the loop pile layer 4 (not shown). This depends on the type of needling, the size and type of the spherical to worm-shaped fiber structure 5 or the openings created in the carrier layer 3.
  • the flat structure can be created with a structured or also patterned upper side and have an uneven surface.
  • the spherical to worm-shaped fiber structures 5 can be placed in a pattern-like manner as the lower layer 6 and needled over the entire surface or laid over the entire surface and z. B. needled in strips. Part of the needled spherical to worm-shaped fiber structure 5 is z. B. between the pole loops, while others may have reached or on the top.
  • they are embedded in a fiber material 7 in the lower layer 6.
  • the spherical to worm-shaped fiber structures 5 are introduced into the loop pile layer 4 by needles from the lower layer 6, their shape or shape having changed compared to the spherical to worm-shaped fiber structures 5 remaining in the lower layer 6, as was described in the previous exemplary embodiment. With a head part 5 ', the spherical to worm-shaped fiber structures 5 fill the loop pile layer 4 or spaces in it, which either exist between the pile loops of the pile yarn 2 or may have been removed during the needling by displacing them (not shown).
  • the deformed spherical to worm-shaped fiber structures 5 are still in the lower layer 6, in which there are still needleless spherical to worm-shaped fiber structures 5.
  • a majority of the spherical to worm-shaped fiber structures 5 protrudes with the head part 5 'over the pile loops of the pile yarn 2, so that a pronounced high-low structure is formed on the top of the fabric 1.
  • the pile loops of the pile yarn 2 and the fiber structures 5 are shown in a schematic manner in FIGS. In fact, they may have different distances or dimensions and e.g. B. arranged closer or closer.
