Definitions

  • the invention relates to a method for manufacturing a waterproof and breathable article of clothing, as well as such an article obtained by implementing such a method.
  • the body gives off perspiration, in particular in the form of water vapour.
  • wearing unsuitable articles of clothing for example conventional waterproof articles intended to protect against the cold and/or inclement weather, can be uncomfortable, in that these articles do not allow the water vapour to be removed towards the exterior.
  • waterproof and breathable articles of clothing which are arranged to prevent the humidity coming from the exterior from penetrating inside said articles while allowing the water vapour generated by the body of the wearer to be removed to the outside.
  • waterproof and breathable articles comprising an outer envelope generally at least water-repellent, an inner lining having thermal insulation properties, as well as a waterproof and breathable insert arranged between said envelope and said lining.
  • the insert comprises in particular an impermeable membrane but which allows the water vapour to pass in order to confer the expected breathability, for example by being microporous or hydrophilic.
  • the presence of water in the vicinity of the insert compromises the removal of the water vapour generated by the body of the wearer, in such a way that said water vapour remains inside the article of clothing and is condensed, which also constitutes discomfort for the wearer.
  • the invention aims to improve prior art by proposing a method for manufacturing an article of clothing wherein a waterproof and breathable barrier is formed directly on the inner surface of the envelope of said article, which makes it possible to prevent water weight gain of said article when it is used in a wet environment while improving its quality and its lifespan.

  • a method for manufacturing a waterproof and breathable article of clothing 1 comprising an envelope 2 which has an inner surface 3 intended to be worn in the vicinity of a portion of the body of a wearer and an outer surface 4 opposite said inner surface.
  • the method comprises providing an article of clothing ( 50 ), turning the envelope over in such a way that the inner surface is facing outwards ( 60 ), coating the outward-facing inner surface with polymer ( 100 ), turning the envelope over in such a way that the inner surface is facing inwards ( 150 ), and impregnating the inner surface with polymer ( 200 ).
  • the article of clothing 1 is a glove of the mitten type, with a compartment for the thumb and a shared compartment for the other fingers.
  • the article of clothing 1 is for example a glove of another type, a shoe, a slipper, a bonnet or a hood.
  • the method provides for forming a waterproof and breathable barrier 5 directly on the inner surface 3 of the envelope 2 , which makes it possible to simply, inexpensively and in a manner that is easy to automate manufacture articles of clothing 1 with complex and varied shapes such as those described hereinabove. As such, the method offers a wide range of choices as for the aesthetics of the articles of clothing 1 to be manufactured.
  • the method provides at least one step of coating ( 100 ), during which the envelope 2 is turned over in such a way that its inner surface 3 is outward-facing ( 60 ), said step providing for coating said inner surface with a first solution 6 with a base of at least one waterproof and breathable polymer.
  • the step of coating ( 100 ) provides for using a first solution 6 comprising a hydrophilic polymer, in particular with a polyurethane base, as much as polyurethane is recognised for its satisfactory properties as a barrier to liquid water and for transferring the water vapour in order to confer the expected breathability.
  • the polymer is used in aqueous phase, which makes it possible to use a first solution 6 devoid of non-aqueous solvent.
  • the outward-facing inner surface is coated with first solution 6 while injecting air into the envelope ( 110 ).
  • Air A under pressure is injected into the envelope 2 during the coating in order to shape it via inflating, which makes it possible to coat its inner surface 3 homogeneously and, in the case where said envelope is assembled by stitching, to prevent the polymer from penetrating inside the envelope 2 through the seams.
  • the pressure of the air A is sufficient to provide for the shaping of the envelope 2 so that the coating perfectly hugs the three-dimensional shape of the envelope 2 .
  • the envelope 2 is placed, after having been turned over, on a base 7 with a shape that is adapted to that of the opening of said envelope, said base being connected to a device 8 for injecting air.
  • the device 8 is arranged to inject air A under pressure into said envelope by the intermediary of said base.
  • the step of coating ( 100 ) provides for coating the inner surface 3 by immersing the envelope 2 in a bath 9 containing the first solution 6 while injecting air into the envelope ( 112 ).
  • the temperature of the bath 9 , the immersion time of the envelope 2 in said bath and/or the concentration of polymer in the solution 6 are varied.
  • the step of coating ( 100 ) provides for coating the inner surface 3 by spraying the polymer solution 6 onto said inner surface 3 while injecting air into the envelope ( 114 ), with the spraying time then being chosen according to the type of the article of clothing 1 and the desired performances.
  • the step of coating ( 100 ) then provides for drying the envelope 2 in order to form a first layer 10 of waterproof and breathable polymer on its outward-facing inner surface 3 ( 120 ).
  • the envelope 2 is placed in an oven, in order to form the layer 10 by cross-linking of the polymer.
  • the step of coating ( 100 ) provides for injecting air under pressure into the envelope 2 while it is being dried, with the pressure of the air being sufficient to guarantee the shaping of said envelope, which makes it possible to dry said envelope homogeneously.
  • the layer 10 is dried on the shaped envelope 2 , a perfect geometrical concordance is guaranteed between said layer and said envelope in order to render the entire inner surface 3 waterproof and breathable.
  • the envelope 2 is subjected, after coating and before drying, to a preliminary light drying, for example by using a fan, in order to remove the bubbles that may have formed on the inner surface 3 .
  • the inner surface 3 is fully covered with a thin waterproof and breathable layer 10 , as shown in FIG. 6B .
  • the layer 10 is formed by cross-linking of the polymer, which allows said layer to be joined with the envelope 2 .
  • the method provides for repeating the steps of coating and drying ( 130 ) at least two times, which makes it possible to vary the thickness of the first layer 10 by superimposition of several sublayers.
  • the step of coating ( 100 ) provides in particular for using first solutions 6 of different compositions at each iteration.
  • the step of drying is omitted or shortened between repetitions to provide an incompletely dry or cured sublayer, permitting better cohesion of the next application of the first solution.
  • the envelope 2 is formed by stitching, and in particular by assembling several parts by stitching, the repetition of the step of coating ( 130 ) makes it possible to guarantee a good coverage of the holes formed by said seams, and therefore a good impermeability of the final article of clothing.
  • the method then provides at least one step of impregnation ( 200 ), during which the envelope 2 is turned over in such a way that the inner surface 3 covered with the first layer 10 of polymer is inward-facing ( 150 ), as shown in FIG. 7B .
  • This step of impregnation ( 200 ) provides for pouring into the envelope 2 a solution 11 with a base of at least one waterproof and breathable polymer ( 210 ).
  • the turned envelope 2 inner surface 3 arranged facing inwards, is arranged on a base 7 with a shape adapted to that of the opening of said envelope, said base being connected to a device 12 for injecting liquid supplied by a tank 13 containing the second polymer solution 11 .
  • the step of impregnation ( 200 ) uses, for the same reasons as said step of coating, a second solution 11 comprising a hydrophilic polymer, in particular with a polyurethane base.
  • the polymer is used in aqueous phase, which makes it possible to use a second solution 11 devoid of non-aqueous solvent.
  • the composition of the first solution 6 is the same as the composition of the second solution 11 , which reduces manufacturing costs and complexity.
  • the composition of the second solution 11 is different from that of the first solution 6 , allowing the selection of advantageously higher or lower viscosity solutions to ensure impregnation without penetrating through the envelope, or for the selection of desired surface properties on the finished product.
  • the step of impregnation ( 200 ) provides for removing the excess solution 11 from the envelope 2 ( 220 ) and for injecting air A under pressure into said envelope ( 230 ), in order to force said solution to penetrate into the seams and into any pores or voids in the first layer 10 in order to guarantee a perfect sealing of the seams and the inner surface.
  • the base 7 is connected to a device 14 for pumping arranged to pump the second solution 11 into the envelope 2 and to return the excess solution 11 into a tank, for example the same tank 13 as that used previously, as shown in FIG. 8A . Then, the base 7 is connected to a device 8 for injecting air arranged to inject air A under pressure into the envelope 2 by the intermediary of said base as shown FIG. 8B .
  • the temperature of the solution 11 can in particular be varied.
  • the envelope 2 in order to improve the aesthetics of the article of clothing 1 , is subjected, after the injection of air A under pressure, to a suitable rinsing in order to remove the excess solution 11 of polymer that may have bled onto the outer surface 4 of said envelope during said injection of air.
  • the step of impregnation ( 200 ) then provides for drying the envelope 2 in order to form a second layer 15 of waterproof and breathable polymer on the first layer 10 ( 240 ).
  • the envelope 2 is placed in an oven, in order to form the second layer 15 by cross-linking of the polymer.
  • the step of impregnation ( 200 ) also provides for injecting air under pressure into the envelope 2 while it is being dried, with the pressure of the air being sufficient to guarantee the shaping of said envelope, which makes it possible to dry said envelope homogeneously, including in the seams.
  • the first layer 10 is covered with a second layer 15 of polymer that is thin, waterproof and breathable, as shown in FIG. 9B .
  • the polymer of the second layer 15 is chosen for its chemical affinity with the polymer of the first layer 10 or, if said first layer comprises a superimposition of sublayers made of different polymers, with the polymer of the last of said sublayers, which allows said second layer to be joined with said first layer, in order to form a waterproof and breathable barrier 5 .
  • the first solution 6 and second solution 11 used by the steps of coating ( 100 ) and of impregnation ( 200 ) are identical, which makes it possible to benefit from a maximum chemical affinity.
  • the step of impregnation ( 200 ) makes it possible to seal the last seam holes or any pores or voids that were not covered after the step of coating ( 100 ), and as such to provide for optimum and reliable impermeability.
  • the method provides for repeating the step of impregnation ( 200 ) at least two times ( 250 ), which makes it possible to vary the thickness of the second layer 15 by superimposition of several sublayers.
  • the step of impregnation ( 200 ) also provides for using solutions 11 of different compositions at each iteration, for example to select desired surface properties for the outermost sublayer while maintaining adequate cohesion of the inner sublayers to each other and to first layer 10 .
  • the combination of the two steps of coating ( 100 ) and of impregnation ( 200 ) makes it possible to confer to the article of clothing 1 a perfect global impermeability, in particular on the seams, while making it possible to retain good grasping, good sensations in terms of touch, and good breathability.
  • a lining 16 is arranged in the envelope 2 in order to cover the inner surface 3 ( 225 ) as shown in FIG. 10B .
  • the step of impregnation ( 200 ) provides for arranging the lining in the envelope 2 before it is dried, in order to fix said lining 16 to said envelope during said drying by the intermediary of the second layer 15 of polymer.
  • the lining is arranged in the envelope 2 during the last iteration.
  • the lining 16 includes at least one layer of material that has thermal insulation properties, for example with a base of cotton, foam or polar fleece.
  • air under pressure is injected into the lining 16 before the second layer of polymer is fully dried or cured, in order to allow said lining 16 to be in close contact with the inner surface 3 of the envelope 2 .
  • the lining is arranged in the envelope 2 after it is impregnated ( 225 ), then the lining—envelope 2 unit is arranged on the base 7 connected to the device 8 for injecting air and air pressure is injected ( 227 ), with the whole then being placed in an oven for drying ( 245 ).
  • the second layer 15 is formed by cross-linking of the polymer and makes it possible, thanks to said cross-linking, to reliably fix the lining to the envelope 2 .
