Definitions

  • the invention relates to compressed nonwoven wipes as well a process for their manufacture.
  • Nonwoven wipes are known as such and are used, for example widely used as cosmetic wipes.
  • the known nonwoven wipes it is disadvantageous that this has a relatively large volume in stockpiling ingest, resulting in a relatively large packaging and Warehousing leads.
  • the present invention is therefore based on the object To create nonwoven wipes that are in stockpiling take up relatively small volume, as well as a procedure specify their manufacture, the inexpensive to do is.
  • the task is related to the manufacturing process of the nonwoven cloths by the features of claim 1 and with regard to the nonwoven cloths by the characteristics of Claim 7 solved.
  • the invention is based on the knowledge that through introduction the nonwoven cloths in a compression form and then compressing the nonwoven cloths can achieve particularly high packing density. This is done the compression of the nonwoven wipes according to the invention such a high compression pressure that the nonwoven cloths not by itself, but only after one De-moisten with a liquid.
  • the Nonwoven wipes can therefore be packaged in a high density be packed and stored in a space-saving manner. First immediately before using the nonwoven wipes again by moistening it with a liquid unfolded. By moistening the non-woven cloths decompressed again so that it is essentially of develop themselves or at least without major ones Let difficulties unfold.
  • Claims 2 to 6 relate to advantageous developments of the method according to the invention.
  • the nonwoven fabric is advantageous according to claim 2 a supply roll and can be drawn in an endless process to be edited.
  • Non-woven wipes for example face masks
  • a suitable application for example a punching tool or a cutting tool.
  • the nonwoven cloths are preferred according to claim 4 by a plunger into the compression mold introduced and according to claim 5 in the dry Condition condensed.
  • the claims 8 to 10 relate to advantageous Developments of the nonwoven fabric according to the invention.
  • the nonwoven cloth has the shape a face mask. There are two eye openings and a mouth opening provided from the nonwoven cloth are separated out. Furthermore, according to claim 8 a nasal perforation can be provided which is a nasal lobe separates from the main part of the nonwoven fabric, the Nose lobes when wearing the face mask on the nose like this rests that the nostrils are exposed. It is advantageous according to claim 9, the nasal perforation to be interrupted by two webs, which can be used without further can be separated. It has been shown that the processing of the nonwoven fabric in particular in the Process step of compacting through these webs is relieved.
  • the nonwoven fabric is preferably according to claim 10 made of a fibrous material, for example viscose and / or polypropylene and / or polyester and / or cellulose. According to a preferred embodiment the non-woven cloth made of 100% viscose.
  • the nonwoven fabric 1 is first of deducted a rotatably suspended supply roll 2 and a folding device 3 supplied. With the nonwoven it is a fibrous material.
  • the nonwoven fabrics according to the invention in a particularly preferred embodiment from 100% Viscose exist. In principle, however, any is suitable fibrous, at least to a small extent absorbent material.
  • the nonwoven web 10 is on the folding device 3 folded in the middle, which is illustrated by the arrow 4 is.
  • a folding shoulder 5 is used can of course also be arranged vertically.
  • the Nonwoven web 10 can also be folded several times to enable multi-layer processing.
  • the Fabric panels are smoothed by guide rollers 6 and 7 and fixed to each other before being punched 8 be fed.
  • the punching device 8 comprises a punching tool 9 made of the two-layer nonwoven web 10 in the embodiment Non-woven cloths 11 punched out in the desired shape.
  • the illustrated embodiment is the Nonwoven wipes 11 around a face mask shown in FIG. 1 for better illustration in the unfolded state is shown, although after punching it out around her The axis of symmetry is simply folded.
  • the punch 9 comprises only one half of symmetry of the nonwoven fabric 11 to be punched out, the axis of symmetry 12 of the nonwoven cloth 11 or the face mask with the folded edge 13 of the two-layer nonwoven web coincides. This has the advantage that the punching out with a high manufacturing effectiveness and at the same time the nonwoven cloth 11 before the compression to be described is already pre-folded.
  • the Nonwoven wipes 11 or the face masks, however unfolded from the nonwoven or the multilayer nonwoven web 10 are punched out.
  • a multilayer Nonwoven web 10 would have the advantage that with each Punching process of several nonwoven cloths or face masks 11 are punched, which also leads to high manufacturing effectiveness leads.
  • the nonwoven cloths 11 or in the embodiment Face masks can, for example, by means of a conveyor belt 14 are removed after punching.
  • nonwoven cloths 11 from the nonwoven web 10 to apply by punching can also be, for example Ultrasonic cutting, thermal cutting with one Hot wire or the like can be used.
  • FIG. 2A and 2B illustrate the process step compressing the nonwoven cloths 11.
  • Fig. 2A process step shown Nonwoven cloths 11 introduced into a compression mold 20.
  • this is done using a plunger 21, which when inserted into the Compression 20 takes the nonwoven cloth 11 and in the Compression form 20 brings.
  • It is preferably located Nonwoven cloth 11 contrary to the illustration in Fig. 2A at Insert into the compression mold 20 in one order Axis of symmetry 12 simply folded state what that Introducing into the compression mold 20 facilitated.
  • the Nonwoven cloth can also be placed in the Compression form 20 can be folded and defined multiple times another defined folded position in the compression form 20 be introduced if this is advantageous in individual cases.
  • the introduction into the compression mold 20 can also be done by other measures, for example by means of suction a negative pressure.
  • a Insertion piston 21 is the diameter of the insertion piston 21 compared to the diameter of the compression mold smaller to avoid jamming of the nonwoven fabric 11 between the wall of the compression mold 20 and the Avoid insertion piston 21. When inserting arises a random multiple folding of the nonwoven cloth 11.
  • the compression takes place in the compression form 20 nonwoven fabric 11 located Compression piston 22 introduced into the compression mold 20 and applied with a high compression pressure.
  • Advantageous are in the compression form 20 or in the compression piston 22 one or more holes to escape the enclosed Air provided.
  • This is done according to the invention Compacting the nonwoven cloths 11 under such a high Compression pressure at a given given Temperature that the nonwoven cloths 11 are not itself, but only after moistening with a Can unfold liquid again.
  • a compression pressure of more than 20 bar, preferably more than 50 bar, required if the non-woven cloths are made of 100% viscose.
  • the fibers of the nonwoven fabric are then ready after this compression networked with each other that the nonwoven cloths in cannot unfold dry again by itself.
  • the compression form 20 has a round cross section, so that the nonwoven cloths 11 into a tablet-like shape be compressed.
  • 2C is a nonwoven cloth 11 in shown in a compressed, tablet-shaped state. These tablet-shaped non-woven wipes are, for example can be packed in tablet tubes.
