Definitions

  • the invention relates to a mixed fiber fleece, in particular as a filling material for bedding, textiles, upholstered furniture, automobile interiors or as insulation or insulation, and a method for its production.
  • a mixed fiber fleece made of sheep's wool and kapok is known, which is used as a filling material for bedding, clothing, children's equipment and the like, in order to take into account above all the hygienic requirements and at the same time to be able to offer a pure natural product that can also be disposed of in an environmentally friendly manner.
  • a disadvantage of this known mixed fiber fleece is, in particular, that although it is washable, part of the bulk of the mixed fiber fleece is lost with each wash, so that the service life of the goods produced with it is limited.
  • the object of the invention is to provide a mixed fiber fleece which retains its properties corresponding to the new condition over a longer period of time and to provide a method for producing such a mixed fiber fleece.
  • the mixed fiber fleece consists of a mixture of fine synthetic fibers such as polyester fibers and kapok fibers
  • a mixed fiber fleece is made available which remains fully washable together with the overall product, the synthetic fiber portion maintaining the bulk in the mixed fiber fleece, where, on the other hand, the kapok portion has an antibacterial effect and guarantees that there is no dust mite, so that the entire product does not have to be washed as often in order to meet the hygienic requirements as bedding that consists only of synthetic fibers.
  • the synthetic fibers and the kapok fibers are homogeneously bonded to one another, so that problem-free further processing is possible and the advantageous properties of the mixed fiber fleece come into their own evenly.
  • individual layers of synthetic fleece or kapok fleece with further individual layers are nonwoven with one another in terms of layer technology, two or more layers can be arranged one above the other.
  • Such layers can consist not only of pure polyester fleece or pure kapok fleece but also of synthetic and kapok fibers which are fleece-bonded to one another, so that any desired requirements for the mixed fiber fleece can be met.
  • the proportion of kapok fibers in the total mixed fiber fleece can be so small that it can just guarantee the absence of house dust mites or can be chosen arbitrarily larger, depending on how high the requirements are or how the overall properties of the mixed fiber fleece should be adjusted.
  • the synthetic fibers made of polyester can optionally consist of solid fibers, hollow fibers and / or 3-D fibers.
  • a mixed fiber fleece is made available which, with the same thickness as a known mixed fiber fleece made of sheep's wool and kapok, is significantly lighter and thus, for example when processing as a filling material for duvets, creates a considerably more airy and pleasant feeling for a user than the well-known, much heavier mixed fiber fleece made from pure natural products.
  • the fibers to be mixed are loosened beforehand mechanically in a predetermined mixing ratio. This process is carried out by a bale opener, in which the fibers are transported over a needle lattice cloth against an opposing roller with needles. The needles on the roller comb the excess fibers from the needle slat band and throw them there. through back to the fibers that are still to be opened, which enables a uniform loading of the next opener system.
  • the pre-opened fibers are then transported to the next opening system designed as a fine opener.
  • This fine opener serves as a second fiber opening device.
  • the premixed fibers are sent here over several rollers topped with sawtooth wire, which have different diameters and sometimes opposite directions of rotation, so that the fibers run more or less parallel to each other and any chunks or tufts are dissolved. This is necessary because the individual fibers of the subsequent ventilation system must be fed separately.
  • the ventilation system consists of two different, approximately 80-200 m long specially coated plastic hoses, which are arranged spirally in a tower. This system also includes two suction fans specially designed for this process, which transport the fibers out of the fine opener through the tower at a precisely measured air speed. The completely homogeneous mixing takes place here, since the two fibers combine in the air flow of the hose and are joined together by a certain friction, which is achieved by the flow velocity.

Abstract

L'invention concerne un non-tissé à fibres mélangées, destiné à être utilisé en particulier comme matière de garnissage pour des articles de literie, des textiles, des meubles rembourrés ou des éléments intérieurs d'automobile ou comme matière d'isolation ou d'insonorisation. L'invention concerne en outre un procédé de production de ce non-tissé à fibres mélangées. Selon l'invention, pour que ce non-tissé conserve pendant une durée prolongée les propriétés qu'il possède à l'état neuf, il est constitué d'un mélange de fines fibres synthétiques, telles que des fibres de polyester, et de fibres de kapok.
