Description

Technical Field

[0001] This invention relates to a method for manufacturing clothing articles with expandable heat dissipation, and clothing articles manufactured by implementing this method.

[0002] This invention is particularly applicable to clothing articles, such as underwear, worn on the torso during sports activities to help regulate the user's temperature and / or perspiration at different stages of the activity. Background Technology

[0003] We know of an underwear from document US-2016 / 0366963 that includes a central section covering the torso and two side sections covering the user's arms respectively, the underwear including air pockets specifically located at the chest, shoulder blades and back.

[0004] Specifically, the garment can be formed from a seamless knitted fabric having overlapping outer and inner pieces, which are then sealed together by adhesive and / or sewing to form an air pocket.

[0005] Also known from document EP-0924999 is a thermal insulation module that can be integrated into clothing such as underwear or tops, the module being equipped with an air bladder that can be inflated by the user, particularly by blowing an air valve that can be inserted into an interface placed on the module, so as to allow the user to adjust the layout of the module according to the intensity of their physical exertion, thereby adjusting its temperature and / or perspiration.

[0006] Specifically, the module can be manufactured by sealing two membranes together at certain locations to form an inflatable air sac, or by folding a single membrane that is sealed on itself to form a peripheral seal and multiple air sacs. Furthermore, to assemble the module onto clothing, one layer of the membrane wall can be pressed onto the fabric, the membrane-free surface of which then forms the outer surface of the garment.

[0007] The purpose of this invention is to improve upon the prior art by providing a manufacturing method for producing clothing articles with integrated thermal insulation networks in a simple manner, and in particular to provide user comfort by imparting expandable heat dissipation.

[0015] Other features and advantages of the invention will become apparent in the following description with reference to the accompanying drawings, wherein:

[0022] [ Figure 3c [From the front view ( )] Figure 3a ), side view ( Figure 3b ) and rear view ( Figure 3b The illustration schematically shows an example of a garment produced by the method described in the foregoing figures. Detailed Implementation

[0023] In conjunction with these figures, a manufacturing method for producing clothing articles with expandable heat dissipation is described below, as well as clothing articles produced by implementing this manufacturing method.

[0024] The garment includes at least one covered section that covers a portion of the user's body. Figure 3a , 3b In 3c, the garment is an undergarment for covering the upper part of a user's body, particularly during sports activities. The garment includes a central section 1 covering the torso and two side sections 2 each covering one of the user's arms.

[0025] In the illustrated embodiment, the section 1 covering the torso includes an inner textile layer 3 and an outer textile layer 4, with an insulating network 5 extending between the inner and outer textile layers. The insulating network includes at least one air septum 6, which is formed by welding portions of membranes 7a and 7b respectively bonded to one of the inner and outer textile layers.

[0026] In the accompanying drawing, the garment includes an air vent 6 that extends over the chest and each shoulder blade. These areas of the body are more sensitive to cold and therefore require greater insulation than the rest of the torso.

[0027] In particular, the garment shown includes a single insulating network 5 having a front section 5a and two rear sections 5b covering the chest and shoulder blades respectively. The front section 5a is in fluid communication with each rear section 5b via a corresponding row 5c of an air duct 6, each of which extends over a covering section covering the clavicle.

[0028] As a variation, the insulating network 5 may extend to other parts of the torso, such as the lower part covering the back and / or the part covering the abdomen, which are more prone to sweating during physical activity. The garment may also include additional networks 5 formed on the covering sections 2 covering the arms, such as additional networks 5 formed on the covering section at the top of the shoulders.

[0029] To form the underwear, fabric layers 3 and 4 together may have a surface density of less than 300 g / m2. Furthermore, the covering sections 1 and 2 of the torso and arms each have appropriate elasticity to allow the underwear to conform to the user's body, thus providing the user with a "second skin" effect.

[0030] Advantageously, the fabric layers 3 and 4 are made together by seamless weaving, which allows the covering section 1 to be formed as a single piece, thus facilitating its manufacture and making it easy to obtain garments with appropriate elasticity.

[0031] Reference Figure 1a , 1b As shown in 1c, a method for manufacturing a garment article with expandable heat dissipation will now be described, the garment article comprising at least one covering section 1 covering a portion of the body, as previously described.

[0032] To obtain such a covering section 1, the manufacturing method involves first manufacturing a tubular textile sleeve 8, which includes a main portion 8a with a geometry similar to that of the covering section 1, and a complementary portion 8b adjacent to the main portion, each having outer walls 9a, 9b. Figure 1a ).

[0033] Advantageously, the main part 8a and the complementary part 8b of the tubular textile sleeve 8 have similar geometries, which facilitates the manufacture of the covering section 1 and thus the manufacture of the entire garment.

[0034] As mentioned earlier, the tubular textile sleeve 8 can be manufactured by seamless knitting, especially by a circular knitting machine, which allows it to be made into a single piece.

[0035] The manufacturing method then involves joining a membrane 7a on the outer wall 9a of the main portion 8a and a membrane 7b on the outer wall 9b of the complementary portion 8b, wherein the membranes are airtight and weldable together. Figure 1b ).

[0036] The films 7a and 7b can be cut from a film of suitable material according to the desired shape and / or size, and then laminated onto the corresponding outer walls 9a and 9b of the main portion 8a and the complementary portion 8b. As a variation, the films 7a and 7b can be formed directly on the outer walls 9a and 9b, for example by coating or extruding a suitable product onto the desired area of ​​the outer walls.

[0037] The manufacturing method then involves rolling the complementary portion 8b onto the main portion 8a by aligning the outer wall 9a of the complementary portion 8b with the outer wall 9a of the main portion 8a to form a covering section 1. This covering section includes the main portion 8a as an inner layer 3 and the complementary portion 8b as an outer layer 4, with at least a portion of the respective films 7a, 7b of the main portion and the complementary portion arranged opposite each other between the inner and outer layers. Figure 1c ).

[0038] In particular, when the covering section 1 is used to be worn around the torso, the main part 8a and the complementary part 8b can be rolled up along the fold line 10, which is used to form the upper collar 11 or the lower hem 12 of the garment.

[0039] Then, in order to complete the manufacture of the covering portion 1, the manufacturing method involves partially welding portions of membranes 7a and 7b one on top of the other to form a heat insulation network 5 between them, the heat insulation network 5 including at least one air inlet 6 extending between layers 3 and 4 of the covering section.

[0040] refer to Figure 1b and 1c The manufacturing method involves placing a membrane 7a, 7b on each of the outer walls 9a, 9b. According to a variation not shown, the same membrane 7a, 7b can be joined to the main portion 8a and the complementary portion 8b of the tubular textile sleeve 8.

[0041] According to one embodiment, at least two membranes 7a, 7b are joined on each outer wall 9a, 9b, and the corresponding welding of the at least two membranes allows at least two thermal insulation networks 5 to be provided between layers 3, 4 of the covered section 1.

[0042] refer to Figure 2 At least a portion 8a, 8b of the tubular textile sleeve 8 may have two regions 13a, 13b with different textile densities, particularly depending on the heat sensitivity of the body part covered by said regions.

[0043] Therefore, the tubular textile sleeve 8 can have a region 13a with a high textile density, which is set opposite to the parts of the body most sensitive to cold, particularly the chest and shoulder blades, in order to provide a greater heat supply in these parts.

[0044] Similarly, the tubular textile sleeve 8 may have a region 13b with a lower textile density, particularly perforated, which is positioned opposite the body parts most prone to sweating, particularly the lower back or abdomen, to facilitate ventilation and perspiration in these areas.

[0045] Specifically, membranes 7a and 7b may be joined to at least one outer wall 9a and 9b of regions 13a and 13b to impart different compressions to the obtained insulation network 5 depending on the positioning of the insulation network on the covered section 1.

[0046] For example, air intestine 6 can:

[0047] - Extend over the high-density textile region 13a to improve insulation levels at the parts of the body most sensitive to cold; and / or

[0048] - Extended over the low-density textile area 13b to keep the sweat-soaked fabric away from the user's skin, thereby preventing the user from getting cold while promoting the evaporation of the sweat.

[0049] The manufacturing method is particularly characterized by welding portions of membranes 7a and 7b together along weld line 14, defining at least one air inlet 6 between the portions of the membrane.

[0050] Specifically, portions of membranes 7a and 7b can be welded together to form at least one air inlet 6, the internal dimensions of which can vary depending on their position on the covered section 1, thereby giving layers 3 and 4 different spacing and / or isolation.

[0051] exist Figure 3a , 3b On 3c, network 5 includes a front segment 5a and two rear segments 5b, each segment having some air intestines 6 arranged in a nested manner with a basically constant cross-section, and the air intestines 6 of a segment 5a, 5b having a length that increases from the inside to the outside.

[0052] In addition, the air intestines 6 of each segment 5a, 5b are connected to each other by an interruption 15 formed in the fusion line 14 of the membrane 7a, and the air intestine 6a on the outside of the front segment 5a is connected to the air intestine 6b of the rear segment 5b by a lateral air intestine 6c extending in a row 5c on the covered segment of the clavicle.

[0053] In a variant not shown, the manufacturing method involves welding portions of membranes 7a and 7b together to form an insulating network 5 comprising, for example, a single air inlet wound around itself.

[0054] Welding of portions of membranes 7a and 7b can be performed, in particular, through the inner layer 3 and outer layer 4 of the covering section 1, with means suitable for performing the welding without damaging the fabric forming the layers.

[0055] Advantageously, the manufacturing method involves equipping the thermal insulation network 5 with a valve 16 for inflating / deflating the air inlet 6, the valve being engaged with the thermal insulation network via the outer layer 4 of the covering section 1, so as to allow the user to access the valve at any time while wearing clothing, especially during sports activities.

[0056] Therefore, the user can, for example, arrange the inflation of the insulation network 5 according to his needs through the interface connected to valve 16, which is especially important during movement.

[0057] For example, users can:

[0058] - Before exercising, inflate the air intestine 6 to provide space for air circulation between his skin and clothing, thus protecting his body from the cold and providing warmth;

[0059] - During exercise, the air vent is deflated to allow the clothing to come into contact with the skin, thereby limiting heat transfer and allowing the textile to absorb sweat; and

[0060] - After exercise, the air bladder is re-inflated to allow the clothing to leave his skin again, thus preventing his body from cooling down rapidly and the unpleasant contact between his skin and the sweat-soaked textiles.

[0061] After obtaining the covered section, the manufacturing method involves producing garment articles, particularly linking the section to other sections 2 that cover other parts of the body via seam 17.

[0062] Therefore, in the illustrated embodiment, the obtained covering section 1 covering the torso is sewn to the covering section 2 covering both arms to form underwear.

[0063] Specifically, the manufacturing method is configured to manufacture multiple covering sections 1, 2 covering different parts of the body according to the steps described above, and then join all these sections 1, 2 together by seam 17 to form a garment article including multiple thermal insulation networks 5 in different locations.
