Definitions

  • the invention first relates to a composite material for forming a closure part of a hook and loop fastener, at least consisting of a flat textile structure with handle, loops, loops, eyelets od. Like. And a carrier film.
  • Such a composite material is generally known from the prior art, but can not be documented in printed form.
  • such a composite consists of a so-called Henkelgewirk, which has a knitted base structure and arranged thereon handles. After the production of this Henkelgewirks the latter is glued to a printed carrier film at a later date, this composite is glued after its assembly into strips ultimately in the production of diapers to form a closure part of a hook and loop fastener on the surface of the diaper.
  • closure tape in particular for diapers with an adhesive zone and a tab zone known, wherein the tab zone again comprises releasable mechanical closure elements, which have on their side facing away from the closure tape side adhesive application.
  • the mechanical closure elements are covered on their adhesive application having side with a separate release tape.
  • a sheet material for the production of adhesive fastener elements in which the carrier material is a self-supporting polymer film, through which a plurality of threads are sewn so that projecting portions arise.
  • the object of the invention is to provide a less expensive composite for forming a closure part of a hook and loop fastener, the further processing is easier to perform.
  • the composite material according to the invention has the great advantage that it can be manufactured substantially more cost-effectively, because even during the manufacture of handles, loops, loops, eyes or the like, a firm connection between the base layer and the textile structure at the same time can be brought about. This eliminates the necessary in the prior art processing step of the bonding of base layer and textile structure, which often led to a disadvantageous manner to an adhesion of the handle.
  • the composite at regular intervals on empty meshes, which are filled by supplied trailing threads, which prevent fringing when dividing the composite in the region of the trailing threads.
  • the textile structure is formed from at least one nonwoven, the only small Has manufacturing costs.
  • the fleece is printed.
  • the nonwoven may also be formed of polypropylene fibers.
  • a further embodiment of the invention is characterized in that the nonwoven is attached to the support layer on the handle side.
  • This has the advantage that the top of the composite gets a very strong textile character.
  • another embodiment of the composite in which the fleece is arranged facing away from the handle side on the support layer has the advantage that the carrier foil, which is usually printed on the top side, is not additionally covered by the fleece, ie the motifs arranged thereupon are ultimately good are visible.
  • the support layer is formed as a carrier film.
  • the carrier film can have restoring forces, by which at least partially the holes caused by the sewing are closed in the carrier film.
  • the carrier film is formed as a mono-, multi-layer or co-extrudate.
  • a further embodiment is characterized in that the support layer is formed as an additional nonwoven layer.
  • the fleece forming the textile structure can be made fluffy and easy to interlock and the additional fleece can be dimensionally stable.
  • the above-mentioned additional nonwoven layer can in a further embodiment facing away from the handle side with a Be provided adhesive layer, which is advantageous for later processing.
  • a further embodiment of the invention is characterized in that the composite is provided on the mesh side with a melt film arranged by pressure and heat treatment, wherein the arrangement of the melt film can be done only by pressure or by heat treatment.
  • This additional arrangement of a melt film makes it possible to seal the perforated through the sewing process many times carrier sheet again. This has advantages in the production of diapers, since the strip-finished composite is transported with suction devices, whereby a certain airtightness of the composite is advantageous.
  • the molten film mesh side is formed as a liquid layer having a solid connection with the composite after cooling.
  • the melt must not be so viscous that it can penetrate through the composite to the handle side.
  • the composite is provided on the mesh side with a film material layer which is rendered into a liquid state by volatile solvents and which, after the solvent has volatilized, forms a solid compound with the composite.
  • the invention relates to a method for producing a handle, loops, loops, eyelets od.
  • Composite having the formation of a closure part of a hook and loop fastener, especially for diapers, substantially formed from a flat, textile structure and a carrier film, which are fastened to each other before the assembly.
  • the main advantage of the method according to the invention is that now for the first time in the stitchbonding machine not only a Henkelgewirk can be produced, which is laminated in an additional processing step with the support layer, but that happens in a simple and cost-effective manner together in the stitchbonded. Added to this is the fact that all problems that arise in connection with the bonding process, such as bonding the handle and a long drying time of the composite omitted.
  • empty stitches are created at regular intervals in the sewing machine, which are filled by trailing threads. This has the advantage that the fringing is contained when cutting the composite in the area of empty mesh.
  • the composite formed of textile structure and supporting layer and connected with sewing threads is cut into strips directly after production.
  • the cutting lines are arranged in the region of the aforementioned empty stitches.
  • an embodiment of the method according to the invention is characterized in that the composite is thermally separated and the thickened cut edges are rolled by the action of two conically adjustable pressure rollers. This is a very simple way of separation, whereby the disadvantageously resulting thickened cut edges can be eliminated by the pressure rollers.
  • the composite at the mesh surface is brought together with a melt film which is placed on the composite by pressure and heat, and the melt film can also be attached only by pressure or heat.
  • the air impermeability of the carrier film can be easily restored.
  • the background to this is the fact that, by sewing on the textile structure and carrier film, the latter has many holes which could possibly be a problem when transporting prefabricated carrier films by means of suction cups.
  • a composite for forming a fastener part of a hook-and-loop fastener is generally designated by the reference numeral 10.
  • Such a composite material is formed according to FIG. 1 from a carrier film 11 and a fleece 12, which are firmly connected to one another via a plurality of sewing threads 13 with the formation of handles 14 and stitches 15.
  • Fig. 2 it can be seen that the order of the layers is different.
  • the carrier film 11 is arranged on the handle side and the fleece 12 on the mesh side.
  • the composite 10 according to FIG. 1 has the advantage that it has a very textile impression on the upper side due to the fleece 12 arranged above the carrier film 11, whereas the composite 10 according to FIG. 2 has a textile impression on the underside and an unillustrated printing of the carrier film on the upper side 11 remains clearly visible.
  • FIG. 3 schematically shows a stitchbonded sewing machine 16 serving to produce the composite 10.
  • a carrier film roll 17, a nonwoven roll 18, and a plurality of sewing thread rolls 19 are arranged.
  • a carrier film 11 and a nonwoven web 12 are introduced together into the stitchbonding machine 16 and sewn there with a plurality of sewing threads 13, so that on Output of the automatic stitching machine 16 of the composite 10 of FIG. 2 has arisen.
  • this composite material 10 is additionally connected to a melt film 20.
  • a melt film roll 21 is arranged behind the stitchbonding machine 16, wherein the melt film 20 is pressed permanently against the mesh side of the composite 10 via a heated pressure roller assembly 22. This creates a three-layer composite 23.
  • FIG. 5 Another composite material 10, in which the carrier film 11 has been replaced by a second nonwoven layer 12 T , is shown in FIG. 5.
  • the handle-side nonwoven layer 12 may be formed as a fluffy hook-friendly fleece, while the second nonwoven layer 12 T has a stabilizing function for the composite 10 as a dimensionally stable nonwoven.
  • FIG. 6 a composite material 10 according to FIG. 5 can be seen, in which an additional adhesive coating K is present on the mesh side as an application aid for the bonding of the composite material to the diapers (not shown).
  • FIG. 7 shows a composite material 10 in which an adhesive layer K is arranged between the nonwoven layer 12 and the second nonwoven layer 12 T.
  • This adhesive layer K stabilizes the layer structure and reduces the air permeability of the composite, thereby simplifying the further processing in diaper production.
