Definitions

  • the present invention relates to a filling product, the base material of which is made of feathers; it also relates to the process for producing this product and to the installation for implementing the process.
  • Feather-based packing products find their application in many industries due to their multiple properties and qualities.
  • This material is made of feathers but it is generally made of feathers, feather quality, feather and / or down depending on the uses. Most of the time, it comes in bulk and its implementation is not the easiest. It has in fact characteristics similar to those of light pulverulent materials, that is to say that it has no shape and that it is very volatile.
  • JP-61-213087 proposes a sheet-like structure in which down, feathers or feathers are entangled with animal fiber and are made integral by the fusion of a synthetic fiber integrated into the mixture.
  • the synthetic fiber with a low melting point is mixed with the filling product to allow fixing by gluing of the down, feather and / or feathers, to the animal fiber which is longer.
  • the present invention provides a filling product based on feathers, feathers and / or down which also has a certain consistency, available for example in the form of plates or in rolls.
  • this product compared to the products described in the aforementioned documents, has the advantage of retaining the properties proper to the feather and to the down, that is to say their insulating power, their swelling property and the feel of it. 'in general.
  • the invention enhances this product and makes it usable in areas where high quality thermal insulation and comfort are sought, such as in furniture, bedding, car seats for example.
  • This product according to the invention is in particular recognizable by the means which make it possible to give it a shape and a volume, better suited to its destination and especially to its use in the various industries for which it is intended.
  • this filling product consists essentially of feathers and of a flexible, coherent structure, in three-dimensional network, which retains and traps said feathers, which structure consists of suitable thermoplastic fibers which are entangled and linked together, and this product results from a process for obtaining detailed below which consists, firstly, in preparing the fibers by working then in carrying out an intimate mixture, by mechanical means of said fibers and feathers, that is to say of these two products of such a different nature, which mixture is then shaped in the form of a sheet then heat treated to achieve the welding and / or bonding of the fibers together.
  • the fibers forming this structure are made up of two-component fibers:
  • the component constituting the core is a synthetic fiber made of a polymer-type material stable at high temperature, that is to say having a softening point high, higher than the temperature of the heat treatment of the mixture, that is to say 200 ° C. for example, the other component on the surface of the fiber, forming a sheath, is made of a material of the polymer type whose softening temperature is less than that of the core, for example between 70 and 180 ° C, allowing to achieve through said heat treatment, a true weld at a point of contact of two of these structural fibers.
  • the length of the structural fibers is between
  • the properties of this basic filling product can also be modified by the addition of complementary fibers.
  • the product can also comprise fibers called volume fibers, which for example have a crimp, preferably a substantially helical shape, which fibers are either natural, artificial, or synthetic with a temperature of change d 'state by degradation or softening which is higher than the welding temperature of the structural fibers, that is to say a temperature close to or higher than that of the core of the structural fibers.
  • the addition of bulk fibers, that is to say crimped fibers improves the swelling character of the product, that is to say its propensity to occupy and keep a certain volume.
  • the product according to the invention may also comprise other constituents endowed with one or more particular functionalities of the anti-bacterial, anti-mite, flame retardant type. These constituents can be specially treated bulk fibers or any other complementary fiber or even feathers or particles added.
  • the filling product consists of feathers, that is to say feathers, feathers, down, in a proportion of between 10 and 80% by weight, preferably of the order of 30 to 60 % and the complement consists of structural fibers and / or a mixture of structural fibers and complementary fibers, bulk fibers or other constituents, in which complement the structural fibers have a proportion which is for example in the order of 10 to 100% by weight.
  • the filling product according to the invention is preferably shaped in the form of a sheet and this sheet can optionally be covered on one of its faces or be completely wrapped, by means of a coating of nonwoven material or 'A film produced by spraying, which coating can also be of the hot-melt type and it is preferably deposited before the heat treatment operation of the sheet so as to weld and / or stick to the structural fibers in particular.
  • This coating promotes the retention of feathers and reduces leaks, during the operations of cutting the web, near the cutting area.
  • the invention also relates to the general process for preparing the filling product detailed previously.
  • This process consists in - preparing an intimate and homogeneous mixture comprising feathers, that is to say feathers, feathers, down, and free fibers made up at least of fibers known as structural fibers, - in forming this mixture in the form of a sheet and, - to carry out a heat treatment with hot air, at an appropriate temperature, sufficient to weld said structural fibers wherever they are in contact with each other and, - to gradually cool the sheet and its structure , before packaging.
  • the operation of preparing the mixture of feathers and fibers consists, firstly, of successively depositing on an endless belt, an appropriate quantity of fibers and then feathers, and subjecting this sandwich to at least a working operation which allows intimate and homogeneous mixing of feathers and fibers before the tablecloth making operation.
  • the fibers before being mixed with the feathers, are subjected to a prior working operation, whether these are structural fibers alone or an assembly made up of said structural fibers, complementary fibers, such as bulk fibers or other constituents having a particular functionality, which fibers and constituents, as the case may be, are distributed in superimposed layers, on an endless belt, in the form of a sandwich, before be subjected to at least one working operation.
  • the process can also consist, before the heat treatment operation of the sheet, of protecting and enveloping said sheet by means of a coating in the form of a nonwoven or in the form of a film or film, deposited by spraying, which coating produced for example a material of the thermoplastic polymer type may also be able to bond by thermal softening with the structural fibers.
  • the invention also relates to the installation for implementing the method detailed above.
  • This installation comprises a cell for storing the filling material, that is to say feathers, feathers and down, and, at least one inlet or cell for storing pre-worked fibers, which cells are arranged to deposit on a carpet without end, a layer of fibers then a layer of feathers, which carpet is placed upstream of a machine called pre-opener which produces an intimate and homogeneous mixture consisting of feathers and free fibers, which installation comprises, after said pre-opener , a coating machine and, behind this coating machine, equipment for heat treatment which makes it possible to carry out the operation of welding the structural fibers at each of their contact points.
  • the installation may include between the pre-opener and the coating machine, one or more machines called pre-opening machines, which further improve the quality of the feather-fiber mixture, which mixture is then sent to a hopper associated with said coating machine.
  • the installation also includes, as necessary, at least one pre-opening machine for fibers and other possible constituents, which pre-opening is fed by an endless belt, which belt circulates under one or more cells in which the fibers, that is to say structural fibers and, optionally, complementary fibers, that is to say bulk fibers and other constituents or fibers having, for example, a particular functionality, which fibers are arranged in layers on said endless belt and the sandwich thus prepared is pre-worked before being mixed with the feathers.
  • at least one pre-opening machine for fibers and other possible constituents which pre-opening is fed by an endless belt, which belt circulates under one or more cells in which the fibers, that is to say structural fibers and, optionally, complementary fibers, that is to say bulk fibers and other constituents or fibers having, for example, a particular functionality, which fibers are arranged in layers on said endless belt and the sandwich thus prepared is pre-worked before being mixed with the feathers.
  • the installation comprises a coating machine of the volumetric chimney type and may optionally be followed by a second coating machine of the pneumatic type for example, which pneumatic coating machine consolidates and reinforces the random distribution of the structural fibers and multiplies the points of contact of said fibers with each other. , by upsetting their arrangement in the mass of the mixture in the form of a sheet, which has the effect of giving the latter an identical resistance to deformation in all directions.
