Definitions

  • the invention relates to a spherical fiber aggregate according to the preamble of claim 1
  • a filler material from molded articles with a round cross-section is known.
  • This filler material is thus formed from spherical fiber aggregates, individual threads having a length of at least 200 mm being used to produce the individual fiber aggregate.
  • These threads are separated from one another by a gas stream, blown into a vessel with a perforated wall, collected therein and rotated by eccentrically blowing a gas stream into the vessel to form a spherical molding. This creates a fiber aggregate that has a greater density in its spatial outer areas than in its core area.
  • Synthetic fibers made of polyamide, polyester, polyacrylic acid, polyvinyl alcohol, polyvinylidene chloride, polyurethane or polyvinyl chloride are used for this unit.
  • Different synthetic fibers can also be mixed, which differ in particular in their thermoplastic properties.
  • these known units cannot interlock or penetrate one another.
  • such a fiber aggregate may have similar properties, in particular in terms of bulk, compression elasticity, softness, thermal insulation, low weight and good adaptation to the body to be wrapped, such as down, it cannot be regarded as an equivalent substitute for down, since it contains the liquid -Down's absorbency is absent
  • Another fiber aggregate is known from EP-A 0.013.427, which consists of spherically intertwined or rolled fibers. These aggregates are free-flowing and rollable and can use natural fibers such as cotton or wool fibers, animal hair such as goat hair, fur hair or the like. or synthetic fibers or a mixture of them. These known aggregates have a needled density and, according to EP-A 0.013.427, are to be laid down to form a layer with one another and / or needled with a carrier layer, in order then to form a textile fabric
  • These fiber aggregates have been made especially for the production of carpets or the like. proven. In principle, they can also be used as filling materials for pillows, blankets or the like. use. If these are synthetic fibers, however, these aggregates can generally absorb almost no moisture. Aggregates with natural fibers, such as wool or the like, can absorb a relatively large amount of moisture, such as sweat or other body deposits, but such aggregates become matted very quickly, which not only clumps in them, but also connects with other, neighboring aggregates and As a result, the individual aggregate and the filling as a whole no longer have the elastic properties that were initially present. These fiber aggregates are therefore less suitable as filling material for pillows and blankets, especially for the bed
  • the invention is therefore based on the object of creating generic spherical fiber aggregates which combine different properties with one another, in particular on the one hand can also absorb moisture as a filler and therefore in particular have natural fibers, but on the other hand do not have their properties similar to those of down, such as large bulkiness, pressure elasticity , Softness, heat insulation ability, light weight and good adaptation to the body to be wrapped
  • the fiber aggregate according to the invention is characterized in that different fibers are arranged in the core of the fiber aggregate than in the casing of the same. This enables the fibers of the aggregate core to be assigned a different task, such as the fibers of the aggregate shell
  • the fibers of the casing can be natural fibers while the fibers of the core are synthetic fibers. Due to the external natural fibers, the fiber aggregate appears to consist only of natural fibers, which is particularly important when these fiber aggregates come into direct or indirect contact with human skin through a covering.
  • the synthetic fibers on the inside can then essentially take on a supporting function for the natural fibers on the outside
  • the fibers of the casing can also take on essentially the mechanical properties, while the fibers in the core of the unit then essentially have the task of absorbing liquid and providing thermal insulation.
  • natural fibers such as e.g. Cotton or sheep wool fibers are arranged, while synthetic and in particular stiffer fibers are provided in the casing
  • Such synthetic fibers should be water-repellent, polypropylene fibers being particularly suitable here
  • the core of the fiber aggregate can also contain fine, in particular moisture-absorbing fibers, while the shell of the aggregate contains coarse, contains moisture-repellent fibers
  • Such fiber aggregates can e.g. in that further other fibers are wound around a fiber aggregate forming the core in a second known balling process step
