Definitions

  • the present invention relates to a process for the preparation and processing of filling materials in the divided state and of low density, of flaky structure and intended more especially for the production of flexible protective envelopes for body use.
  • the invention relates more particularly to the preparation, treatment and conditioning of materials such as down intended for the production of body thermal protection envelopes such as eiderdowns, quilts, anoraks, winter clothes, sleeping bags, etc. ...
  • the invention therefore essentially relates to the preparation and treatment of packing materials for protective articles with high insulating power or "adiathermic" power and using natural duvets taken essentially from aquatic animals.
  • the down differs from the feather by its absence of rigid rod, by its lightness and its property of storing the air.
  • the feather that makes up the outer plumage of birds has a primary shaft or axis, with its horny tube, which the stem surmounts accompanied by its beards planted laterally.
  • the beards are broken down into barbules and barbicelles.
  • the poultry feather is very flat. It is sometimes used in the stuffing of poor quality cushions and pillows. It does not contain air.
  • the feather of aquatic animals is arched, it is used as a bedding filling: feather beds, pillows, bolsters, cushions (we lie on it). It does not contain air, but has excellent compressibility.
  • the manufacturers of down articles therefore use a raw material which has undergone deterioration due to excess compression, the downs becoming entangled in each other and the filaments separating from the flake, creating dusts which reduce the volume of immobilized air and cause respiratory discomfort and allergic reactions of users.
  • a body insulation blanket (a sleeping bag, an anorak or any garment) has a much more effective and high insulating and thermal protection power when it is used. in the dry state.
  • the method according to the present invention aims precisely to improve and considerably increase the insulation power of the material used by dimensional increase in the volume of the unit flakes which are blocked in their increased dimensional structure while they are made very largely insensitive to outdoor humidity.
  • US Patents 2,715,086 and 2,714,767 also relate to feather treatments which can be coated with wax, resin or elastomer to improve their filling power; but this treatment is provided for feathers precisely with a view to bringing their properties closer to those of down; and the treatment has no effect on the dimensional structure of the product.
  • US Patent 2,714,767 describes a drum-shaped cage and a treatment of feathers introduced into the cage to receive a coating of wax or elastomeric resin.
  • US Patent 2,739,391 further describes a machine for drying and expanding feathers which also receive an electrostatic charge.
  • the present invention allows an increase in the volume of each unit flake trapping a greater amount of air in the same weight of material and allowing to increase the efficiency of the product thus treated.
  • Another no less important object of the invention is to stabilize the down in the dimensional structure which has thus been conferred on it.
  • the treatment according to the invention will allow the maintenance of protective structures (duvets, sleeping bags, anoraks) under improved and simplified conditions allowing an increase in the life of the article.
  • the invention will make it possible to confer on lower quality duvets, for example second choice duvets or used duvets, renovated properties of thermal resistance by modification of their dimensional structures and their resistance to humidity.
  • the coating resin has a high surface tension with respect to water and is chosen, in particular, from fluorinated resins or resins based on silicone.
  • the multiple filaments that make up the flake are in the initial state largely entangled and packed in on themselves, consequently reducing the total volume they occupy from the central nucleus; this corresponds to the natural state of the down during its live use on the body of the animal, the down being then largely impregnated with the natural oils exuded by the body of the animal and being necessarily compressed by the upper layers of the plumage.
  • the heat treatment which will be described below makes it possible to develop the filaments which resume a general position substantially radial from the central core by relaxing and then allowing the flakes of down to occupy a volume space corresponding substantially to a sphere whose radius would correspond to the average length of the filaments.
  • the operative treatment according to the invention begins with a dehydration phase.
  • the thermal dehydration is carried out in the same apparatus used subsequently for the next phase of stabilization by coating with a coating material.
  • an example of apparatus used in the context of the implementation of the invention comprises an enclosure 1 provided with an inlet 2 at its base and a discharge opening 3 at the top, and constituted of a box.
  • a rotary drum 4 Inside this enclosure is mounted a rotary drum 4 whose side walls 5 are full or preferably made of glass plates, cooperating with the side glass walls of the enclosure 1 thereby allowing visibility inside of the cylinder to allow control of operations. Access openings are provided (but not shown in the drawing).
  • the peripheral walls 6,6 ′, 7,7 ′ of the drum consist of an openwork structure, for example a perforated sheet or a mesh (for example made of expanded metal).
  • Radial paddles 8,8 ', 9,9' are arranged towards the periphery of the drum to improve the mixing of the material.
  • the hot air is evacuated at the top 3 and it can advantageously be recycled after passage through means allowing the elimination of humidity and heating.
  • the average humidity level of the air trapped within each flake of the down was brought to a level of between 20 and 25% corresponding to the dimensional state of the down as shown in FIG. 2.
  • the drum is rotated by conventional means around the hub 10; the slow rotation allows continuous mixing of the flakes of down introduced into the drum; the flakes fall slowly down where they are taken up by the pallets 8,8 'etc ... and lifted towards the upper part from where they escape by gravity to fall slowly down when meeting the air flow hot rising to which they regularly give up their humidity gradually.
  • the down remains in suspension in the drum, always driven in slow rotation (one to two revolutions per minute).
  • the injection pipe 11 which occupies the central axis of the drum and which opens on the outside at 12 connected to a pressurized source, to inject inside the volume of the drum in the state of mist or mist the solution consisting of a coating resin in a solvent.
  • the internal axial tube 11 is provided for this purpose with ejection nozzles 13, 13 ′ which spread in the interior space of the drum a mist consisting of the resin in solution.
  • Solvents with rapid evaporation are preferably chosen, the solvents being discharged via the upper outlet 3.
  • water-repellent resins chosen from the group comprising fluorinated resins and silicone-based resins will be used.
  • the proportion of resins per 20 kilos of down will be of the order of 40 to 50 grams in a liter of solvent.
  • the treatment ends in the polymerization phase during which air brought to 130 °. is blown into the enclosure containing the drum, while continuing the slow movement of rotation and agitation of the mixture.
  • the resin polymerizes, the chemical bonds which are established to obtain the high molecular weight chains giving the resin film its final mechanical structure makes it possible to crystallize the flake in the expanded state which the previous phase of dehydration and thermal elevation will have made it possible to achieve.
  • the assembly is allowed to cool to obtain an expanded down, developed and stabilized in this inflated dimensional structure, the humidity level of which is reduced to a rate of 25% maximum.
  • the presence of the water-repellent resin film on the filaments thanks to the high surface tension of the resin film relative to the water vapor, allows the down to repel the air charged with ambient humidity, the air dry content in the interstitial spaces between the filaments of each flake remaining in place without hygrometric exchange.
  • the product having undergone the treatment is then immediately used for the filling of finished products and articles of use such as quilts, sleeping bags, anoraks, etc.
  • the down thus used and which has undergone the treatment described above has an increase in volume varying from 30 to 40% depending on the qualities; this means that to obtain the same insulation it is possible to use a quantity of material 30 to 50% lower; which represents a saving of up to 50% in the price of the raw material.
  • the implementation of the method according to the invention makes it possible to obtain, in the manufacture of body protection articles filled with down, extremely competitive cost prices combined with exceptional profitability.
  • the article filled with down according to the invention escapes the constraints of the cold which would risk reducing its volume and its insulating power, just as it escapes the constraints of humidity greatly reducing its insulating power and which would also entail risks of mold.
  • the article produced according to the invention no longer needs to be ventilated every day (to evacuate the moisture stored in body contact) since the article resists the absorption of moisture.
  • the article can be exposed to the sun because the filaments thanks to the coating resin film are largely protected from radiation in the ultraviolet.
  • the packing product thanks to the treatment of the invention, is made unassailable by vermin and parasites.
  • the process of the invention by stabilizing the down in its structure avoids the formation of elements detaching from the filaments and which constitute dust; this prevents respiratory discomfort in sensitized subjects and users.
  • the service life of the article comprising the lining according to the invention is greatly increased due to the contributions made by the treatment; greater mechanical resistance to compression and cancellation of the stresses linked to humidity, parasites and devitalization are obtained, in particular under the effect of solar radiation.
  • the article according to the invention also represents properties of perfect resistance to repeated dry cleaning or to water cleaning.
  • the method according to the invention advantageously allows not only the considerable improvement in the properties and qualities of new down, but it also allows the recovery and renovation of so-called "down duvets".
  • Coated down which is 4 to 5 times cheaper than new down can, thanks to the process of the invention, find the same properties and the same qualities as new down, which allows the recovery of old down and a considerable saving of raw material.
  • Tests and controls carried out by the applicant made it possible to compare the adiathermic power of the down treated in accordance with the invention compared to a conventional down.
  • the drum 4 can then be produced in great length and along a slightly inclined axis; the down introduced at the highest part would be discharged at the lowest part after passing slowly through the cylinder passing in a first phase corresponding to a dehydration phase in which it is subjected to a current of hot air, then to a phase of coating with the fog of the resin solution followed by the final phase of polymerization by thermal elevation with final cooling.
