Definitions

  • the invention relates to a process for the production of cotton swabs from an absorbent material for absorbing liquids, from fiber material such as cotton, viscose and from synthetic melt fibers, which fiber material forms a card web which heats for the production of the swabs for the purpose of joining the melt fibers and then for forming the shape the swab is embossed or punched.
  • the invention relates to a system for producing such a cotton swab by a method of the type specified.
  • a cotton swab is known, the fiber body of which has synthetic melt fibers distributed uniformly over the entire volume, which are connected to the adjacent fibers by at least superficial pressure-free melting of the fibers.
  • the distribution of the melt fibers through the entire body is an unnecessary effort if only melting on the surface is to take place. Limitation in the case of a pressure-free melting by heating to only the surface areas is not possible.
  • the result is a cotton swab with an undefined structure and thus also with an undefined pumping speed.
  • the liquid absorption capacity is limited.
  • a hygienic fleece and its manufacturing method are known, from which one also produces cotton swabs according to the first-mentioned document.
  • a cotton tape covered with a lint-proof nonwoven fabric is known, which is produced by a hot-stamped surface consolidation of the thermoplastic fiber portion of the cotton tape with a nonwoven cover layer.
  • the entire cross section of the lint-proof nonwoven fabric is interspersed with melt fibers and is consolidated in a calender with at least one heated embossed structure.
  • the proportion of fibers to be thermoplastic deformed can amount to approximately 20% of the total fiber mass.
  • This embodiment differs from the first-mentioned known embodiment by a hot-stamped surface hardening, so that a specific shape is possible.
  • a hot-stamped surface hardening with heating also leads to an undefined product insofar as the fusion of crossing fibers cannot be measured in the depth of the body. This also applies to the production of a hot-stamped embossed pattern on the top.
  • a melt-fiber-free cotton swab is also known, which is joined together by compression into shaped bodies with stabilizing compression. This is evident from US Pat. No. 3,005,543.
  • Such a cotton swab produced by compaction between rollers with recesses without applying heat and solidification at the edges by compression in such a way that this creates bond webs, is easy to fray on the surface, especially when rubbed.
  • Such cotton swabs do not meet market needs because they can be rubbed on easily and can be fogged up in use without achieving sufficient abrasion or cleaning.
  • the invention has for its object to provide a method of the type mentioned for the production of a cotton swab, especially a pile web, for a particularly inexpensive swab design, which has a large dimensional stability with large suction capacity and at the same time has an abrasion-resistant surface, and also a cheap design a device for producing such a cotton swab is intended.
  • This object is achieved by a production in which a card web in multiple excess width with respect to the width of at least one cotton swab blank is produced represents and in the edge portions of this card web melt fibers are introduced and that this card web is folded in a zigzag shape to a multilayer web of smaller width corresponding to the at least one cotton swab, so that at least the outermost layers of the fold are provided with the melt fibers.
  • a card web can be achieved in a surprisingly simple and economical manner as a starting material for the production of a cotton swab with a layering which only has surface sections with melt fibers that are defined in depth at the top and bottom.
  • a gathering of several layers in sandwich-type would be disadvantageous and complex, because for each layer a separate production line with card or card and then the merging would have to be provided.
  • a cardboard web or a multi-layer cotton web with only melt fibers introduced into the outer layers can be produced in a simple manner, with an arbitrarily thin outer layer with melt fibers being adjustable by the respective dimensioning of the adjacent sections of the card web and the dimensioning of the fold width is.
  • melt fiber content only in the outer layers, so that even when heat is applied, the depth of penetration of which cannot be defined, a connection always takes place only in the amount of these layer thicknesses. It is taken into account that even if the layers are loosely compressed, a physical connection is produced, but the connection by the connecting fusion fibers takes place only on the outside. A net-like covering can hereby be brought about.
  • a feature of the production according to the invention is that the folded card web between form rollers ge shapes and is heated.
  • Folding is advantageously included in such a way that at least two, advantageously more, outer layers are provided with the melt fibers at the top and bottom outside the middle layers. As a result, a stronger outer layer is formed around the absorbent pad of the molded body which is held together unconnected in the interior.
  • the folding strips expediently have the same widths. Also included is a fold in which folds with different depths are provided, folds of smaller depth preferably being formed in the middle region than outside in the region of the layer strips with the melt fibers. In this way, certain cross sections can be generated, which are determined by the design of a folding sheet used.
  • the cardboard web is advantageously produced from three adjacent sections, of which the outer sections are a mixture of fiber material, such as cotton or viscose with melt fibers and the middle section consists only of fiber material, such as cotton or viscose, and that the three sections are fed to a card for the production of a cardboard web which is then folded up. This results in a process that practically requires only one card in a multi-layer version.
  • a further advantageous embodiment provides that the folded web is subjected to an edge-to-edge compression in addition to an essentially pressure-free central region and the compressed edge regions and the unpressurized surfaces of the central region are heated to activate the melt fibers .
  • a cotton swab or a suction pad with a particularly loose but defined suction body and abrasion-resistant surface can be produced, as was previously not possible.
  • This cohesion also forms the basis for an abrasion surface when the cotton swab is used for abrasion is because here a line harder and therefore advantageous frictional surface is created over a higher absorbent.
  • a total of about 80% of conventional cotton wool, e.g. B. from 100% cellulose, preferably with a dtex of 2.8 to 3.6 and a fiber length of 30 to 40 mm and about 20% of a thermoplastic fiber is used.
  • the approx. 20% of the thermoplastic fibers which expression also includes a fiber that can only be melted on the surface, concentrate on the edge sections, so that there is then a corresponding distribution of width between the middle section and marginal sections result in much higher proportions. From this point of view, a composition of 80% cotton or 80% viscose or in a different mixing ratio and z. B.
  • melt fibers 2.2 dtex / 40 mm included. Only examples are given here, materials being specified, but in particular the melt fiber content in the edge sections is not restricted to the quantities specified, but can be much higher. Corresponding other materials can also be used, even if the proportions differ.
  • a cotton swab which has a loosely combined, fiber-fiber-free fiber layer on the inside, but is combined on the surfaces by fibers connected to one another.
  • a system for producing a cotton swab described according to the specified methods has a device for forming a web with three adjacent fiber strips. This device is followed by a card or card for pile formation and in the working direction behind the card is a laying device arranged, for the folded web a conveyor, an embossing tool and a heating device are arranged, the latter of which can be part of the embossing tool.
  • the laying device is a folding device known per se, which overlays a web in certain width sections in a zigzag shape. It can advantageously also be designed as a folding plate. Such folding sheets are also known.
  • the reference to the embossing tool is only an indication of an advantageous embodiment. It is expressly pointed out that hot air heating can also be provided, at which hot air is blown through at selected points which are determined by the guideway.
  • the device for forming a web with three adjacent fiber strips is designed as a filling shaft, in the outer sections of which melt fibers or the fiber mixture with the melt fibers and in the middle section fibers without melt fibers are introduced.
  • the device for forming the web is designed with three fiber strips lying next to one another as a batteur wrap.
  • a filling shaft 1 at the entrance This is followed by a card or card 2, on which a card web 3 is produced, which is fed to a laying device, which in the example is a folding plate and is designated by the reference number 4 .
  • Such laying devices but also folding plates 4 used with a corresponding effect, are known per se.
  • a folding sheet 4 the card web is folded up such that its outer sections or strips 5, 6 form the cover layers of a folded web and material sheet 7.
  • Such a laying device or fold Sheet metal causes a zigzag-shaped laying or folding according to Fig. 3 a, from which it can be seen that certain strips 22, 23; 28, 29 are formed and stacked one on top of the other, these strips mentioned as edge strips according to.
  • Fig. 3 a of the relevant description have special properties.
  • the pile and material web formed by the laying or folding is pulled off the folding plate by means of a driven pair of transport rollers 8 and fed to a roller or embossing arrangement.
  • This consists of an upper driven embossing roller 10 and a lower embossing roller 11.
  • Both embossing rollers have shape recesses in their peripheral surfaces, in which the shaped bodies of the web 7 are practically depressurized, but at the edges of the web 7 between the individual shaped bodies and along the outside continuously Edges are pressed together.
  • At least one of the rollers 10, 11, expediently both, are provided with a heating device 37, 38, for example electrical heating elements, so that a temperature in the order of magnitude of approximately 140 ° C. can be achieved.
  • the embossed material runs with the surface of the roller, which is driven in the direction of the arrow, to a removal device 12.
  • a cutting roller 13 runs on the surface of the roller 11 in order to cut through embossed intermediate webs between shaped bodies which form cotton swabs, so that then, for example, individual cotton swabs 14, 15 ... are removed.
  • the conveyor belt of the removal device 12 is driven by a drive motor, not shown, as are the other parts.
  • roller 11 in the sector between the cutting roller 13 and the un tere reversal point can be designed or provided with covers that individual cotton swabs are safely dropped onto the transport device 12.
  • the folding plate 4 has several folding webs 24 to 27 in the schematic representation. These represent only individual folding webs across the width of the card web 3.
  • the folding webs are each shown in FIG. 1 at the same height, so that a folding or folding according to FIG. 3a he follows. This is an advantageous embodiment. It is also included that the folding webs have different heights over the circumference or the width of the folding plate, for example in that middle folding webs 25, 26 have a lower height than the outwardly adjacent folding webs, so that the shaped body created in the center its melt fiber-free area has narrower folding strips and in this respect a pillow shape of a swab is reinforced.
  • the outer connection then takes place in the area of the outer sections or strips 5, 6, while a cushion is formed in the middle that shows itself in the pile or material web 7 with curvature.
  • a card web 3 consists of fiber material, but melted fibers, for example in a proportion of approximately 20%, are contained in the edge strips 22, 23.
  • the cross section of the card web according to FIG. 2 is shown at the top in FIG. 3.
  • a simple zigzag-shaped layering is shown in FIG. 3a, the outer edge strips 22, 23; 28, 29 are made of the material interspersed with melt fibers.
  • the folds have the same width, it being evident that, for example, two outer edge strips are provided with melt fibers.
  • outer edge strips can be joined together directly, in this connection creating a border of a suction pad which can have curved surfaces.
  • the embossing rollers 10, 11 with the shape recesses distributed around the circumference run against one another under elastic compression, so that compression occurs in the contact zones, but in the shape recesses depending on the depth thereof and the formation of the folded material, this can pass through without pressure and through the heating elements arranged in Both rolls are melted out in the area of the webs between the shaped bodies and on the surfaces of the cotton cushions at a dimensioned depth in which melt fibers are contained.
  • Heating elements can be arranged radially symmetrically around the circumference in the embossing rollers or else arranged stationary so that heating takes place in the region of the feed of the web 7.
  • the resulting swabs have a solidified edge and a central body, which is covered by a quasi network-like border, in which passages or gaps of fibers crossing and connecting in different directions are bordered, in the present case the border of defined design and depth is.
  • a body with particularly good absorption properties remains in the middle area.
  • a width dimensioning of the outer sections of the card web 3 is possible.
  • a central section 31 500 mm and the outer sections 32, 33 can each be 250 mm wide.
  • the widths are based on the intended widths of the fold strips to a multiple of the latter.
  • Feed sections 34, 35 and 36 are assigned to all sections for the fiber entry, wherein the devices at 34, 35 can be combined according to the clamp 37 to form a common feed.
  • Such filling shafts are known per se.
  • the thickness of the outer layers provided with melt fibers can be easily determined with regard to the fold width of the folding plate 4, the variations due to different folding depths also being reserved.
