Method for Manufacturing a Waterproof and Breathable Article of Clothing

Abstract

The invention relates to a method for manufacturing a waterproof and breathable article of clothing 1 comprising an envelope 2 that has inner 3 and outer 4 surfaces, the method involving: at least one step of coating (100), during which the inner surface 3 is outward-facing, comprising coating the outward-facing inner surface with a solution 6 with a base of at least one polymer, with air A under pressure being injected into the envelope during the coating, then drying the envelope in order to form a first layer 10 of waterproof and breathable polymer on the inner surface; and at least one step of impregnation (200), during which the inner surface 3 is inward-facing, comprising pouring into the envelope a solution 11 with a base of at least one polymer, removing the excess solution 11, injecting air A under pressure into the envelope, and drying the envelope in order to form a second layer 15 of waterproof and breathable polymer on the first layer 10.

AI Technical Summary

Benefits of technology

The invention proposes a method for making clothing with a waterproof and breathable barrier on the inside, to prevent water weight gain and improve quality and lifespan.

Problems solved by technology

However, 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.

However, these articles do not provide entire satisfaction, in that their manufacture is long and expensive.

However, this water, by being retained as such in the article of clothing, can over time generate a sensation of cold and / or humidity for the wearer, thus rendering the wearing of said article unpleasant for said wearer.

Furthermore, 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.

In addition, when the wearer is exposed to wind, the water retained between the envelope and the insert evaporates slowly, which also generates a sensation of cold for the wearer.

Moreover, the drying time of the article of clothing is very greatly increased, which renders its use less pleasant after a first use in high humidity conditions.
