Definitions

  • the invention relates to a process for producing compressed nonwoven fabrics.
  • Nonwoven fabrics are known as such and For example, they are used as cosmetic wipes used in many ways.
  • the known nonwoven fabric towels is disadvantageous that this in the storage a occupy a relatively large volume, resulting in a relative large packaging and storage costs leads.
  • the present invention is therefore the The object of the invention is to provide nonwoven fabrics which are at the stocking occupy a relatively small volume, and to provide a method of making the same, which is inexpensive to carry out.
  • the task is in terms of the process for producing the nonwoven fabrics by the features of claim 1, solved.
  • the invention is based on the knowledge that by introducing the Vilesstofftücher in a Komprimierform and then compacting the nonwoven fabrics a particularly high packing density reach.
  • the compacting of the nonwoven fabrics takes place according to the invention under such a high Compression that the nonwoven fabrics do not by itself, but only after a moistening with a Unfold the liquid again.
  • the non-woven cloths can therefore save space in a high packing density packed and stored. Only immediately before using the nonwoven fabrics they are unfolded by moistening with a liquid again. By moistening the nonwoven fabrics are decompressed again, so that they are essentially by itself unfold or at least without cause greater difficulties.
  • Claims 2 to 5 relate to advantageous Further developments of the method according to the invention.
  • the nonwoven fabric is according to claim 2 advantageously deducted from a supply roll and can be processed in a continuous process.
  • it is according to claim 3 advantageous to fold the nonwoven fabric in the middle and to apply the non-woven cloths by means of a dispenser the only one half of symmetry of the nonwoven fabric includes. In this way, at a rational Manufacturing a high symmetry accuracy of nonwoven fabrics reached.
  • a Ausbringmaschine is suitable, for example a punch or a cutting tool.
  • the nonwoven fabrics are according to claim 4 by an introduction piston in introduced the Komprimierform and according to the claim 4 compressed in the dry state.
  • the Nonwoven cloths alternatively be moistened before compacting, in to moisten the moistened state and during the Compacting or subsequently drying. Of the Compression pressure can then be lower.
  • the non-woven fabric has the shape of a face mask. There are two eye openings and one Mouth opening provided from the nonwoven cloth are separated out. Furthermore, can a nose perforation be provided, the one Nose flap of the main part of the nonwoven fabric separates, taking the nose lobe while wearing the face mask rests on the nose so that the nostrils exposed. That's it advantageous, the nasal perforation by two To break webs, which in use easily can be separated. It has shown, that the processing of the nonwoven fabric cloth in particular in the step of compacting through them Webs is relieved.
  • the nonwoven fabric consists preferably of a fibrous material, For example, viscose and / or polypropylene and / or Polyester and / or pulp. According to one preferred embodiment is the nonwoven fabric sheet 100% viscose.
  • the nonwoven fabric 1 initially by a rotatably hung supply roll 2 withdrawn and fed to a folding device 3. at The nonwoven fabric is a fibrous material.
  • Besides viscose are also polypropylene, polyester and Pulp particularly suitable, wherein the inventive Nonwoven fabrics in a particularly preferred Embodiment consist of 100% viscose. In principle, however, any fibrous material is suitable, at least to a small extent absorbent material.
  • the nonwoven web 10 folded centrally in the embodiment, which is illustrated by the arrow 4. This serves a Faltschulter 5, which of course also arranged vertically can be.
  • the nonwoven web 10 may also be folded several times to a multi-layer finishing to enable.
  • the fabric will be smoothed by guide rollers 6 and 7 and each other fixed before being fed to a punching device 8.
  • the punching device 8 comprises a punching tool 9, the two-layered in the embodiment Nonwoven web 10, the nonwoven fabric sheets 11 in the desired Punch out shape.
  • these are the reading cloths 11 to a face mask, in Fig. 1 for the better Illustrated in the unfolded state is, although they are after punching out theirs Symmetry axis is simply folded.
  • the punching tool 9 comprises only one Symmetrie half of neurosciencestanzenden nonwoven fabric 11, wherein the axis of symmetry 12 of the nonwoven fabric 11 and the face mask with the folding edge 13 of the two-ply nonwoven web coincides. This has the Advantage that the punching with a high production efficiency takes place and at the same time the nonwoven fabric 11 already before the compression to be described just prefolded.
  • the nonwoven fabrics could 11 or the face masks but also unfolded from the nonwoven fabric or the multilayer nonwoven web 10 are punched out.
  • a multilayered Nonwoven web 10 would have the advantage that with each Punching several nonwoven cloths or face masks 11 are punched, which also to a high manufacturing efficiency leads.
  • the face masks can conveyed away by a conveyor belt 14 after punching become.
  • nonwoven fabric sheets 11 from the nonwoven web 10 by punching, for example also an ultrasonic cutting, a thermal Cutting with a hot wire or the like be used.
  • FIGS. 2A and 2B illustrate the method step the compacting of the nonwoven fabric sheets 11.
  • the nonwoven fabric sheets 11 are in a Komprimierform 20 introduced, by means of an insertion piston 21, the Inserting into the compression mold 20 the nonwoven fabric sheet 11 entrains and brings in the Komprimierform 20.
  • the nonwoven fabric 11 is opposite the representation in Fig. 2A when introduced into the Compression mold 20 in one around its axis of symmetry 12 simply folded folding state, what the introduction facilitated in the compression mold 20.
  • the nonwoven cloth may also be prior to insertion into the compression mold 20 can be folded multiple times and in another defined folding layer introduced into the compression mold 20 if this is advantageous in individual cases.
  • a compression piston 22 becomes the compression mold 20 introduced and with a high compression pressure applied.
  • a compression piston 22 becomes the compression mold 20 introduced and with a high compression pressure applied.
  • these are advantageous in the Komprimierform 20 or in the compression piston 22 one or several holes to escape the trapped Air provided. According to the invention, this is done Compacting the nonwoven fabric sheets 11 under such a high compression pressure at a given preset Temperature that the nonwoven fabric towels 11 not by itself, but only after a moistening can unfold with a liquid again.
  • a compression pressure of more than 20 bar, preferably more than 50 bar, required if the nonwoven fabrics from 100 % Viscose exist.
  • the fibers of the nonwoven fabric are then networked with each other after this compression, that the nonwoven fabrics in the dry state can not unfold again by itself.
  • the compression mold 20 has a round Cross-section, so that the nonwoven fabric towels 11 to be compressed a tablet-like shape.
  • Fig. 2C is a nonwoven fabric sheet 11 in a compressed, tablet-shaped State shown. This tablet-shaped Nonwoven fabrics are for example in tablet tubes packable.
  • On the compression piston 22 On the underside an inscription may be provided, which in the compressed nonwoven fabric sheets 11 an inscription 23, for example, a trademark or a note of use, impresses. Basically, it is also possible to Nonwoven cloths 11 in any other form to compress.
  • Fig. 3 shows in an enlarged view an embodiment of a unfolded nonwoven fabric 11 in the form of a face mask.
  • the punching device 8 are of the form of a human Face mask with two eye openings 24 and a mouth opening 25 punched out. Further, a nose perforation 26 is punched, the one Nose tabs 27 of the main part 28 of the face mask separates.
  • the nasal flap 27 is connected 29 and two webs 30 with the main part 28 of the Face mask connected.
  • the webs 30 serve to further processing after punching, in particular the introduction into the compression mold 20 to facilitate.
  • the webs 30 may after unfolding the face mask be severed in the wet state without further ado, so that when using the face mask the nose flap 26 rests on the nose and the nostrils releases.
  • the eye openings 24, Mouth opening 25 and the nose perforation 26 can also be created with a cutting tool.
  • the unfolding of the inventively prepared Nonwoven fabrics 11 may be, for example, by means of water, but also by means of any other liquid or pharmaceutical or cosmetic solution.
  • the inventive method is also suitable for manufacturing of compressed nonwoven fabrics in others Shape, of other materials and for other purposes.
