Definitions

  • the invention relates to an aggregate containing fibers, e.g. as filling material for blankets or pillows, as upholstery material or as a filter, and a process for its production.
  • Aggregates containing fibers are e.g. used as filling for blankets or pillows, as upholstery material or as a filter. These are usually non-woven fabrics. These can be consolidated by a needle-punched nonwoven process, with needling needles partially gripping individual fibers and aligning them in the nonwoven.
  • Such non-woven fabrics are usually produced by stacking fibers into a web by means of a fiber card. Although it is possible to arrange webs with different fibers across the same thickness by means of different cards arranged one after the other, it is also possible to deposit different fibers simultaneously on one card.
  • the web-shaped product however, has a uniform thickness due to the type of manufacture, which can only be varied by laying differently many webs on top of one another over part of the surface.
  • the product must therefore be considered essentially two-dimensional, although it has a certain thickness.
  • a known aggregate containing fibers cannot therefore be formed into any three-dimensional body. Also, different fibers cannot be mixed in any three-dimensional manner.
  • the invention has for its object to provide a generic unit in which the fibers are arranged and distributed three-dimensionally in a desired manner and also - as long as this is desired - and which has better properties, in particular as a filler.
  • the aggregate consists of fiber balls that consist of spherically entangled fibers, the individual fiber balls being connected to each other.
  • the fiber balls are individually made from fibers as individualized fiber aggregates and then, for example, in one surface - one or more layers - or to any room structure, for example stored in a mold and connected to one another to form a preferably one-piece flat or spatial structure.
  • Such fiber balls are e.g. known from EP-A-0.203.469. These fiber balls known from there can e.g. can be used as loose filling and cushioning material. These fiber balls consist of spirally crimped polyester fibers with a length of about 10 to 60 mm and a diameter of between 1 and 15 mm. The fiber balls have an elasticity, through which the balls recover significantly after a compression - even over a long time (recovery rate of 80%). The fiber balls have a cohesion of less than 6 Newtons, preferably 4.5 Newtons or less (according to a measurement method described there).
  • the fiber balls move very easily within a filling, especially if this filling is used for a pillow or a duvet. If the sleeper lies with his head in the middle of a pillow filled with such fiber balls, this pillow pushes through very easily in the support area. If a duvet filled with such fiber balls is shaken up, the fiber balls move - similar to down - and collect in a corner or on an edge. In order to prevent this at least in part, the fiber balls in the pillow must have a relatively high density, which is why the pillows themselves become very heavy. As a result, the pillow in turn loses its "softness", which some people consider feel uncomfortable. A duvet must be filled with more fiber balls or - better - quilted.
  • Spherical fiber aggregates are also known from EP-A-0.013.427, in which fibers are tangled into fiber balls. These fiber balls have a diameter of at least 3 mm. The balls can have a diameter of up to 50 mm. The fibers used there have a length of at least 15 mm, preferably between 40 and 120 mm. These fiber balls have a density between 0.01 and 0.1 g / cm3.
  • the fibers of these fiber balls can be natural fibers, e.g. Cotton or wool fibers, animal hair or the like. or synthetic fibers, e.g. Polyamide, polyester, polypropylene fibers or the like. or a mixture of these. In particular, these fiber balls can be crimped fibers, e.g. be crimped synthetic fibers.
  • Such fiber balls have hitherto been used essentially for textile fabrics, in particular for carpet manufacture, for clothing fabrics, bed covers, decorative fabrics or textile coverings.
  • the fiber balls are needled as flat structures with one another and / or with a carrier layer. However, they are pressed together very strongly, so that such a flat structure is very hard and e.g. can not be used as a pillow.
  • These fiber balls, as described in EP-A-0.013.427, are suitable as filler material if the individual fiber balls are bound with a binder which ensures that the individual balls do not dissolve.
  • Both types of known fiber balls are very difficult to distribute evenly compared to a nonwoven fabric if they e.g. are to be placed in a ceiling envelope or if they are to be distributed over a larger area as elastic cushioning material with the same thickness.
  • the Fiber balls according to the invention connected by means of connecting fibers.
  • These can be fibers of the individual fiber balls, which are each connected to fibers of another fiber ball. This connection between two fibers can be made by gluing the two fibers at intersection points.
  • binding fibers are preferably so-called binding fibers.
  • These binding fibers can be present in the aggregate in addition to the fiber balls, but according to an advantageous embodiment of the invention, the individual fiber balls themselves have both binding fibers and other fibers. However, all fibers of the individual fiber balls can also be binding fibers.
  • binding fibers are preferably melting fibers that have a melting temperature that is lower than the melting temperature of other fibers of the filling material. These fusible fibers can then be melted by applying heat, whereupon they adhere to adjacent fibers, be it fusible fibers or other fibers.
  • the binder fibers can also be thermoplastic fibers, especially water-soluble fibers, e.g. Polyvinyl alcohol fibers, which are activated by dissolving and form a connection with other fibers of the overall aggregate.
  • the binding fibers can also be adhesive fibers.
  • the binding fibers are stiffer and / or coarser than the other fibers.
  • the binding fibers in particular if they are part of the fiber balls, are then not parallel to the other fibers of the fiber balls, but can even spur out of the fiber balls. It is then possible in particular then to connect the fiber balls to one another only via the protruding fiber ends of the binding fibers, as a result of which the flat structure formed from the fiber balls becomes very conformable and drapable.
  • the unit as a filling material for Duvets adapts very well to the body shape of the person covered underneath.
  • thermoplastic fibers especially water-soluble fibers, e.g. Polyvinyl alcohol fibers
  • the compounds can e.g. after quilting a duvet can be solved by washing the finished duvet.
  • connections between fiber balls of one level each are different from the connections between fiber balls of two superimposed levels, e.g. the connection between the levels is released, while the connection between the fiber balls of a level remains.
  • the user also has the power to make the unit thinner than it was delivered to it in its original state.
  • the fiber balls of a fabric with one or more superposed planes are connected to each other by binding fibers which are arranged in the fiber balls themselves, be it that the ends of these binding fibers spike out of the fiber balls, or that the fiber balls are a shell from meltable binding fibers.
  • a similarly shaped flat structure can now be arranged above, a layer of individual meltable binding fibers being arranged between the two, by means of which the two flat structures are connected to one another. Are then only these individual binding fibers e.g. water-soluble, washing the aggregate allows one sheet to be separated from the other without the sheet itself dissolving.
  • the individual fiber balls can only be connected to one another by individual additional binding fibers be connected, which was placed, for example, like a net over and / or under a layer of fiber balls and glued to it after melting.
  • connections between the individual fibers of different fiber balls can also be designed so loosely that these connections e.g. solve by tapping a blanket or pillow with a tapping broom.
  • the aggregate containing the fiber balls can be rolled, bent and folded, and pushed and pushed together.
  • Such an aggregate can be handled in a variety of ways even without a casing.
  • Such a training is particularly suitable for the transport of fiber balls.
  • the unit can also be made thicker within a non-quilted bedspread by rolling up or folding over one end, so that e.g. more fiber balls are intentionally arranged in the sensitive foot area than in the area facing the head. This can be done by the user himself. If the rolled-up or folded end is still stapled, this remains the case even after shaking the blanket. With down or the well-known fiber balls, this is not easy for the user to accomplish.
  • the unit can be arranged in a casing.
  • This can be, for example, a fabric cover, such as that used for duvets or pillows.
  • the insert By creating the insert beforehand, namely the unit according to the invention, it can have and maintain any desired shape and thickness.
  • Such an insert can have different fibers at the foot end and / or be thicker than at the head end. So far you have this Differences in thickness achieved by quilting the inlet, while maintaining thermal bridges in the area of the quilting. Such disadvantages no longer occur with the unit according to the invention.
  • Such an insert can also be connected to the inside of the cover. Such a connection can be obtained by means of the connecting fibers of the fiber balls.
  • the fiber balls can also be arranged on and connected to a carrier.
  • the fiber balls are very strongly compressed by the needling process used. This is no longer the case with an assembly according to the invention glued to a carrier.
  • Such a shell or the carrier can consist of a fabric or of a perforated film, preferably made of a plastic.
  • a film can e.g. be a slotted plastic film shrunk into a net, as it is sold under the brand "XIRONET" by the company XIRO AG, CH-3185 Schmitten.
  • XIRONET a slotted plastic film shrunk into a net
  • Such a net becomes sticky when exposed to heat, so that the fiber balls can be glued to this net by exposure to heat. The fiber balls then do not need to be adhesive or fusible, or they need not be fused.
  • Such a network can also be activated under the influence of pressure.
  • the fiber balls adjacent to the shell or the carrier are only connected to it via binding fibers.
  • the fiber balls are e.g. glued, sewn, needled or stitched onto the cover or the carrier.
  • the unit itself can form a shell.
  • Loose fiber balls, individual fibers, non-woven fabrics, but preferably a non-fiber-containing material can be filled into this envelope.
  • the latter can be down or feathers or even solid particles such as activated carbon particles or powder, ion exchanger, sand, seeds, fertilizer or the like. act.
  • the unit according to the invention consists of at least one layer of fiber balls. These fiber balls have to touch each other to be connected. This situation must therefore be relatively closed.
  • Fiber balls of different diameters, different colors or with different fibers can be used. A large variety of designs of the desired unit can thus be achieved. Such a large variety of designs or the like is known with the known nonwovens. not reachable.
  • the fiber balls of the unit can now also be filled with a particularly granular material.
  • material can also be arranged between the fiber balls.
  • These can be the same materials that were mentioned above in the context of filling the envelope formed by the fiber balls.
  • This material can also be material contained in or between the fiber balls, such as bog, clay, herbal powder, kaolin, almond bran, cream or the like. act.
  • the method according to the invention for producing aggregates from fiber balls consists of arranging a collection of fiber balls produced and made from spherically entangled fibers and / or threads using the known methods and arranging them in a desired shape and connecting these fiber balls to one another.
  • the fiber balls are connected by means of connecting fibers, which are preferably binding fibers that are activated after the informing. Fiber balls containing binding fibers or separate binding fibers inserted between the fiber balls can be used.
  • Melting fibers can be used as binding fibers, the fiber balls arranged in the desired shape preferably at an elevated temperature subjected to at least the melting temperature of the binding fibers.

  • fibers can now be brought into a desired shape before activating the binding fibers.
  • fibers can also be produced in any desired spatial shape. In this way, molds can be filled with the fiber balls, whereupon the binding fibers are activated and a spatial structure corresponding to the shape can be removed from the mold.
  • Filters can also be manufactured, with e.g. a layer of large fiber balls is placed on which smaller fiber balls as the actual filter or also e.g. Activated carbon is given as a filter material, whereupon this second layer is in turn covered with larger fiber balls.
  • a ring of fiber balls can be placed on the edge of the actual filter layer, which prevents the activated carbon particles from falling out laterally or the like. prevented.
