Description

Technical Field

[0001] The present invention relates to footwear, comprising at least one textile boot having one or more heat-melted textile portions and a sole element, wherein the at least one textile boot is a three-dimensional textile covering including a sole portion, and the sole element is selected, for example, from a midsole element, an outsole element, or a combination thereof. Background Technology

[0002] Traditional footwear typically comprises an upper and a sole structure. The upper is attached to the sole structure and forms a foot-receiving volume within the footwear to comfortably accommodate and secure the foot. The sole structure is attached to the lower area of ​​the upper and is operatively positioned between the foot and the upper. In athletic footwear, the sole structure may include an outsole and a midsole. The midsole typically comprises a polymer foam material that absorbs shocks from the ground upon impact, thus reducing the impact on the foot and leg during walking, running, or other walking activities. The sole structure may also include an lining positioned within the receiving volume and near the lower surface of the foot to enhance comfort. The sole is traditionally attached to the upper by means of strobel lasting during the bonding of the various sole elements, particularly the insole, midsole, and outsole. Methods for manufacturing traditional shoes require dozens of steps and can generate significant waste due to material cutting.

[0003] Therefore, there is a search for methods to simplify footwear manufacturing, particularly by reducing the number of steps and / or the consumption of energy and materials. This is also part of the search for manufacturing methods that can be implemented as close as possible to the footwear's point of use to reduce its carbon impact, facilitate inventory management, and allow for customization.

[0004] Specifically, this modification is achieved by eliminating the stitching steps that primarily shape the initial planar upper in three dimensions. The upper is obtained from one or more components, and is no longer derived from multiple pieces added together by stitching.

[0005] Therefore, WO2019 / 234374A1 proposes a first textile boot, formed directly in three dimensions at the exit of a textile machine (e.g., a knitting machine), which is partially heat-meltable and serves as an upper, which is then attached to the outsole. The upper is reinforced by setting a second, partially heat-meltable, three-dimensional textile boot around the first boot by wrapping around the joint between the first inner shoe and the outsole, thereby improving resistance to delamination. This simplifies the manufacturing process by significantly reducing the number of manufacturing steps. However, such footwear, including an upper formed by the stacking of two, three, or four textile boots, may be too heavy for some activities, particularly sports. For example, the standard weight of footwear used for practicing soccer is approximately 165g to 200g.

[0006] Therefore, there is a need to reduce the weight of footwear (especially for footwear that can be adapted to the weight applied for a specific sport), while improving their comfort by allowing a wide range of possible functions (reinforcement, cushioning, stiffening, etc.), and this is to improve their comfort in a localized way in terms of the volume of footwear, while maintaining the generally desired properties such as abrasion resistance, delamination resistance, and flexibility. Summary of the Invention

[0007] The present invention relates to a type of footwear that solves the above-mentioned problems and a method for manufacturing such an article.

[0008] Therefore, the present invention relates to a lightweight footwear, particularly for sports activities (e.g., but not limited to: football, basketball, hiking, running, cycling...), which is a lightweight footwear that can locally functionalize the upper of the lightweight footwear and simplify the manufacturing method of the lightweight footwear.

[0009] Therefore, according to a first aspect, the present invention relates to a footwear comprising a main textile element, the main textile element including a sole portion having at least partially attached to a sole element, the main textile element further including one or more heat-melted textile portions. The sole portion includes a first through-hole, and the main textile element includes at least one first additional textile portion (A), the first additional textile portion being of a textile construction consistent with the main textile boot and connected to the first through-hole.

[0010] Advantageously, the first additional textile section (A) is not a textile boot and allows for the functionalization of the footwear, for example, by functionalizing a portion of the inner or outer surface of the main textile boot or even the joint between the main textile boot and the sole element. The main textile boot is preferably in the form of a substantially hollow, elongated structure, such as a tube. The first through-hole provided on the sole portion of the main textile boot is advantageously used for manufacturing one or more additional textile sections, such as the first additional textile section (A), uniform with the main textile boot on a textile machine (particularly a knitting machine). This arrangement allows for savings in the setting of auxiliary textile boots and thus regulates the quality of the footwear. Furthermore, the fact that the additional textile section is a fabric construction uniform with the main textile boot simplifies the method for manufacturing the upper. It is also advantageous to place the additional textile section for the thermoforming or hot-pressing steps described below.

[0011] In one embodiment, the main textile boot and, optionally, the auxiliary textile boot described below, each have a generally hollow and elongated shape. Specifically, the generally hollow and elongated shape is substantially tubular and includes a first through-hole and a second through-hole that expands into its internal volume (including the foot-accommodating volume). The second through-hole preferably forms an opening for introducing the foot into the foot-accommodating volume of the footwear. The first through-hole is located on the sole portion of the main textile boot, particularly in the forefoot or heel portion, or in the middle region of the foot (particularly including the arch).

[0012] Preferably, in practice, the first additional textile section (A) is knitted first, then one or more other additional textile sections may be knitted, and finally the main textile boot is knitted, while being connected to the first additional textile section at least at the height of the first through-hole. Therefore, in a single knitting step, the first additional textile section (A) is preferably knitted simultaneously with the main textile boot.

[0013] Preferably, the knitted main textile boot and / or auxiliary textile boot and / or main textile element and / or first additional textile part and / or second additional textile part and / or third additional textile part and / or fourth additional textile part.

[0014] First Additional Textile Section (A)

[0016] Preferably, the first additional textile portion (A) is connected to the first through-opening textile (in particular, a knitted connection).

[0017] The first additional textile portion (A) is preferably joined to the edge of the first through opening by knitting, particularly along the edge of its upper.

[0018] The first additional textile portion (A) and optionally the second additional textile portion (B) and / or the third additional textile portion (C) and / or the fourth additional textile portion (D) preferably comprise a first textile layer and a second textile layer, particularly a first textile layer and a second textile layer that are substantially overlapped. More preferably, the first textile layer and the second textile layer are attached together along at least one edge selected from their upper edge, lower edge, outer edge, and inner edge, particularly along their upper and lower edges. Preferably, the upper edges of the first textile layer and the second textile layer are particularly knitted to the edge of the first or second through-opening.

[0019] Preferably, the first textile layer and / or the second textile layer of the first additional textile portion (A) each comprise one or more heat-melted textile portions.

[0020] The first additional textile section (A) can ensure one or more functions as described herein, and, for example, form a front hard cap, a rear reinforcement, or a cushioning area. The cushioning area can be configured to be positioned under the user's feet.

[0021] The first additional textile portion may at least partially cover the sole portion of the main textile boot (e.g., in the front and / or rear portion of the sole portion), and / or may at least partially cover the front and / or rear and / or inner and / or outer portions of the main textile boot.

[0022] Preferably, the ratio of the mass of the thermally melted textile portion of the first textile layer and / or the second textile layer of the first additional textile part (A) to the total mass of the first textile layer and / or the second textile layer is greater than or equal to 50%, more preferably greater than or equal to 80%, and particularly greater than or equal to 90%.

[0023] Preferably, the footwear article herein includes a longitudinal axis L extending substantially between the rear and front of the article. The footwear also includes a lateral axis T, which, in particular, is substantially perpendicular to the longitudinal axis L and extends between the inner and outer edges of the footwear.

[0045] One or more multifilament yarns can be one or more textured yarns FDY (fully stretched yarn), DTY (stretch textured yarn), or POY (partially oriented yarn) or a mixture thereof.

[0046] One or more fully or partially heat-melted yarns are yarns comprising one or more heat-melted components, such as a first component having a melting temperature less than or equal to the heat-processing temperature of footwear, and optionally a second component having a melting temperature or degradation temperature greater than the heat-processing temperature of footwear. The melting temperature or degradation temperature of the second component, or the melting temperature or degradation temperature of the non-heat-melted material according to the invention, is higher than the melting temperature of the first component.

[0047] The bicomponent yarn can be core-sheath type, where the core comprises / is substantially composed of the second component, and the sheath comprises / is substantially composed of the first component.

[0048] One or more yarns that are fully or partially heat-melted can be one or more single-component yarns with a melting temperature less than or equal to the heat processing temperature of footwear.

[0049] The single-component heat-melted yarns (each) have a fineness preferably between 300 and 900 fineness (including the boundary), particularly between 400 and 800 fineness (including the boundary), and especially approximately 600 fineness.

[0050] The first component may be selected from polyurethane (especially thermoplastic polyurethane), polyamide (such as polyamide 6 or polyamide 66), polyolefin (such as propylene (PP) or polyethylene (PE)), preferably polyurethane.

Elastic yarn preferably comprises an elastic core (particularly an elastic core made of elastic fibers) and optionally comprises one or more core-spun yarns, particularly core-spun yarns from List I or List II cited above. Elongation can be measured using the standard ASTM D1578-93 (2016). By definition, elastic yarn is not heat-melted. Therefore, elastic yarn is made of one or more materials with a melting temperature and / or degradation temperature higher than the maximum heat-processing temperature of footwear.

[0056] The knitting machine can be a circular knitting machine (preferably a small diameter) or a straight knitting machine (preferably with a reduced needle bed width), wherein the knitting machine is used to knit the main textile element, and thus for knitting the main textile boot and the first additional textile section (A) and may be used for knitting section B, section C or section D or auxiliary textile boot (described below).

[0057] The main textile element, particularly the main textile boot and / or the first additional textile section (A) (or part of part B, part of part C and / or part of part D), can be in the form of a weft knitted piece or a warp knitted piece. In particular, the main textile element is non-woven, but the main textile element is preferably in the form of a weft knitted piece (the needle is formed in the weft direction).

[0058] shoe sole components

[0059] The sole element can be a midsole element, an outsole element, or a combination thereof.

[0060] The outsole element and / or midsole element and / or sole element each have an inner surface and an outer surface. Specifically, the inner surface is oriented towards the sole portion of the main textile boot, and the outer surface is oriented towards the outer side of the footwear. In particular, the outer surface contacts the ground relative to the outsole during operation. The sole element can be glued, thermally bonded, and / or sewn to the sole portion of the main textile boot, or it can be obtained by direct extrusion or injection molding and (overcoating) molding or additive manufacturing on the sole portion of the main textile boot.

[0061] The sole element is preferably a molded or three-dimensional textile piece that is wholly or partially bonded to the sole portion of the main textile boot during the hot-pressing step, thereby allowing the formation of heat-melted textile portions. Preferably, one or more heat-melted textile portions adhere to the inner surface of the sole element. More preferably, one or more heat-melted portions of the sole element and the inner surface comprise the same material, for example, polyurethane. This arrangement facilitates adhesion between the heat-melted portions (particularly the sole portion) and the inner surface of the sole element during hot pressing.

[0062] The outsole may include one or more protrusions projecting from its outer surface, particularly one or more protrusions intended to contact the ground, said one or more protrusions may be one or more cleats, or heel pads or shock-absorbing components.

[0063] The sole components may be made of one or more materials selected from: polyurethane, especially thermoplastic plastics, thermoplastic elastomers, silicone resins, natural or synthetic rubbers such as ethylene-vinyl acetate (EVA) (e.g., styrene-butadiene rubber, EPDM (ethylene propylene diene monomer) rubber), polyamides or mixtures thereof.

[0064] Preferably, one or more protrusions protruding from the outer surface of the outsole are also made of one or more materials selected from the above-mentioned materials.

[0065] In this article, we will understand the joint as the area where the sole element is joined to the main textile boot.

[0066] The main textile element and / or auxiliary textile boot may include one or more partitioned areas, that is, one or more partitioned areas that are locally functionalized according to a specific arrangement of yarns and according to the nature and fineness of the yarns.

[0067] Preferably, the footwear according to the invention is footwear for sports activities, such as (but not limited to): football, basketball, hiking, running, cycling...

[0068] In the first variation, the main textile indoor shoe includes an outer surface, and a first additional textile portion partially covers the outer surface of the main textile boot.

[0069] Preferably, the first additional textile portion (A) protrudes from the outside of the main textile boot and partially wraps around it by rotating against the outer surface of the main textile boot.

[0070] Preferably, the first additional textile portion (A) partially covers the toe of the main textile boot, and partially covers the outer and inner portions of the main textile boot, and may cover the front portion of the main textile boot.

[0071] Depending on the size chosen for the first additional textile section (A), in particular, the main textile boot can be covered more or less by changing the height of section (A), that is, by changing the distance that essentially separates its upper and lower edges.

[0072] In the second variation, the main textile indoor shoe includes an inner surface, and a first additional textile portion partially wraps around the inner surface of the main textile boot.

[0075] In the third variation, a first additional textile portion (A) at least partially covers the sole element, and in particular, the first additional textile portion (A) includes an intermediate textile portion disposed between the sole portion of the main textile boot and the sole element.

[0076] Advantageously, it locally improves the anti-delamination between the sole portion of the main textile boot and the sole element, without requiring an additional textile boot that covers the entire joint area between the main textile boot and the sole element. Therefore, it reduces the weight of the final upper, including the main textile element.

[0077] Preferably, the first additional textile portion, also marked (A) in the remainder of this document, protrudes from the exterior of the main textile boot.

[0078] Preferably, the first additional textile portion includes an intermediate textile portion disposed between the sole portion of the main textile boot and the sole element, and a wrapping textile portion, particularly, the wrapping textile portion being an extension of the intermediate textile portion, the wrapping textile portion partially wrapping the sole element.

[0079] If the footwear does not include the first additional textile section (A), the joint between the sole element and the main textile boot will include a rigid area formed by the sole element in contact with the flexible area (formed separately by the main textile boot), such that the flexible area of ​​the main textile boot will be worn down and will form a weakness that promotes delamination with the sole element.

[0080] In the footwear according to the invention, the joint includes one or more flexible additional textile layers (including at least a first additional textile portion (A)) that extend between the sole portion of the main textile boot and the sole element, and partially wrap around the sole element. This arrangement allows for localized reinforcement of the main textile boot and the joint between the main textile boot and the sole element.

This arrangement facilitates the attachment of the first additional textile portion (A) to the sole element because the heat-melted textile portion forms a bonding area between the first textile layer and the sole element.

[0084] Preferably, the ratio of the mass of one or more heat-melted textile portions of the first textile layer to the total mass of the first textile layer is less than or equal to 60%, even more preferably less than or equal to 40%, and particularly greater than or equal to 30%.

[0088] Preferably, the first additional textile portion (A), in particular its textile wrapping portion, also partially covers the outer surface of the sole element, and more particularly, covers the area adjacent to the surrounding edge disposed on the outer surface of the sole element.

[0089] This setup allows for improved delamination resistance by strengthening the attachment between the main textile elements and the sole elements.

[0090] The first additional textile portion (A) may partially cover the periphery of the front portion of the sole element (in which case the first through opening is in the front portion of the sole portion) (particularly for footwear used for practicing football), or may partially cover the periphery of the rear portion of the sole element (in which case the first through opening is in the rear portion of the sole portion) (particularly for footwear used for practicing basketball).

[0091] In the fifth variant, the first additional textile portion (A) includes one or more heat-melted textile portions that are at least partially coated with the sole element.

[0092] Specifically, one or more of the heat-melted textile portions are bonded to the sole element.

[0093] Preferably, the intermediate textile portion and / or the wrapping textile portion each comprise one or more heat-melted textile portions.

[0094] In the sixth variant, the first additional textile portion (A) includes a first textile layer and a second textile layer (particularly the first and second textile layers that are substantially overlapped), and a receiving volume disposed between the first layer and the second layer.

[0095] Preferably, the first and second layers are not substantially integral with each other along their surfaces.

[0098] Preferably, the first textile bonding portion substantially completely or partially surrounds the first through-hole provided in the sole portion of the main textile boot.

[0099] The textile bonding section facilitates the attachment of the main textile boot to the additional part (A) and absorbs the positional changes of the first additional textile part (A) during the hot pressing step.

[0100] In the eighth variant, the first textile bonding portion includes one or more heat-melted textile portions, said one or more heat-melted textile portions being equivalent to at least 50% by mass of the total mass of the first textile bonding portion, particularly at least 80%, particularly at least 90%.

[0101] The textile bonding portion is preferably invisible on footwear because it is actually completely heat-melted.

[0172] Unless otherwise stated, variations, definitions, and embodiments of the first and / or second aspects of the present invention may be combined independently of each other.

[0173] Typically, the first additional textile part (A) can be the second additional textile part (B), the third additional textile part (C), or the fourth textile part (D), and thus includes / has one or more features of the parts (B), (C), or (D) selected independently of each other.

[0174] According to a second aspect, the present invention relates to a method for manufacturing footwear, particularly a method for manufacturing footwear according to any variation of the embodiments of the first aspect of the invention (especially the first to eighteenth variations), comprising the following steps:

[0175] (i) Provide a main textile element, the main textile element including a main textile boot having a sole portion and including one or more heat-fusible textile portions;

[0176] (ii) subjecting the first textile element to a temperature that allows the one or more heat-fusible portions to melt;

[0181] During the hot-pressing step, an inflatable flexible overlay or inflatable preform, specifically having a substantially foot-shaped form, is placed in the foot-receiving volume of the main textile boot. The assembly, including the main textile element, optionally including auxiliary textile elements, and sole elements, is then positioned in two or more parts within a mold. Once the mold is closed, the inflatable overlay is inflated to press the main textile boot against the inner wall of the mold, and to press the first and / or second and / or third and / or fourth auxiliary textile elements against the inner and / or outer surfaces of the main textile boot and / or the sole elements and / or the inner wall of the mold they cover. Heat is simultaneously applied to the molten, heat-fusible portions, resulting in the heat-fusible portions. The assembly is then cooled, preferably with the inflatable overlay remaining inflated during cooling.

[0182] This heat-pressing step can be applied to textile elements already attached to the sole element, and may also be applied to auxiliary textile boots. In this case, if the sole portion of the main textile boot and / or the auxiliary textile boot includes heat-melted textile portions, these reinforce the attachment to the sole element.

[0183] This hot-pressing step can also be applied to textile elements without a sole component, and may be applied to auxiliary textile boots. The sole component is then attached (by gluing, by heat bonding, by stitching, or any other equivalent technique known to those skilled in the art) to the resulting hot-pressed upper.

[0184] Preferably, the footwear includes an upper, which includes a main textile element, the main textile element optionally having other additional textile parts (B and / or C and / or D), and optionally also having an auxiliary textile boot.

[0186] All variations (particularly variations one to eighteen) of the embodiments of the first aspect of the invention, as well as the embodiments, preferred arrangements and definitions, can be independent of each other or by combining variations of the embodiments of the second aspect of the invention with reference to the invention.

[0187] Preferably, in this document, the term "thermally fusible" refers to an element prior to its heat-fusion in relation to a method for manufacturing a sole structure or footwear, and the term "thermally fusible" refers to the same element after its heat-fusion in relation to the resulting sole structure or footwear.

[0206] Figure 1 A first example of a main textile element 100 according to the invention, disposed on a preform 10 and including a main textile boot 200 and a first additional textile portion (A) 300, is presented. The first additional textile portion (A) includes a middle textile portion 320 and a wrapping textile portion 330. The main textile boot 200 includes a sole portion 205, an inner portion 210, an outer portion, a rear portion 215, and a front portion 220, as well as a through opening 225 for inserting a foot into the internal volume of the main textile boot 200 corresponding to the foot-receiving volume of footwear 700. The main textile element 100 may include a temporary elastic textile element 110 that allows the outer and inner edges of the stitching portion 218 of the main textile boot 200 to be held at a substantially constant distance, particularly during the thermoforming step.

[0207] The main textile boot 200 has a hollow elongated shape and includes a first through opening 235 and a second through opening. The first through opening is enlarged into the internal volume of the main textile boot 200 and is located in the front 206 of the sole portion 205. The second through opening corresponds to the opening 225 for introducing the foot.

[0208] The first additional textile portion (A) 200 is connected to the first through opening 235 (particularly to the edge of the opening 235) (in particular, a knitted connection) and protrudes from the edge of the first through opening 235 to the outside of the main textile boot 200.

[0209] The main textile boot 200 preferably includes a first textile bonding portion 230, which specifically comprises one or more at least partially heat-fusible yarns. The first textile bonding portion 230 is partially bordered to the periphery of the first through opening 235. Preferably, the first bonding portion 230 is disposed in the front portion 206 of the sole portion 205 and is composed of at least partially heat-fusible yarns, particularly monofilaments and single-component heat-fusible yarns.

[0210] The main textile boot 200 also includes a partially annular textile area 240 surrounding an opening 225 for introducing the foot.

[0211] The main textile element 100 is in the form of a knitted piece with a uniform knitted structure. The annular region 240 is preferably an n-shaped structure. p-ribbed needle form (e.g., with 1) It is in the form of rib, and may optionally include one or more elastic yarns.

[0212] Preferably, the first additional textile portion (A) 300 is knitted and is a textile (knitted) construction uniform with the main knitted textile element 100. The first portion (A) 300 includes a first textile layer 340 and a second textile layer 350, which are substantially overlapped and comprise one or more at least partially heat-fusible yarns. The first textile layer 340 comprises one or more at least partially heat-fusible yarns, accounting for less than 50% by weight of its total mass, and in particular, comprises one or more at least partially heat-fusible yarns, accounting for less than 20% by weight of its total mass. The second textile layer 350 comprises one or more at least partially heat-fusible yarns, accounting for more than 80% by weight of its total mass, and in particular, consists of one or more at least partially heat-fusible yarns.

[0213] The main textile element 100 includes an unfolded position in which it exits the internal volume of the main textile boot 200 through the first through opening 235. Figure 3 and Figure 4 The second additional textile portion (B) 400 is visible in the image. This second additional textile portion (B) 400 is preferably knitted and is knittedly connected to the first opening 235, so that it is a knitted construction that is consistent with the main textile boot 200.

[0214] In operation, the second additional textile portion (B) 400 is folded within the internal volume of the main textile boot 200 and abuts against the inner surface of the main textile boot 200, partially covering the outer portion 212 and inner portion 210 of the front portion 206 of the main textile boot 200, and partially covering the front portion 215 of the main textile boot 200. The second additional textile portion (B) 400 preferably comprises a first textile layer 410 and a second textile layer 420, which are substantially overlapped and comprise one or more at least partially heat-fusible yarns. Specifically, the first textile layer 410 and the second textile layer 420 are composed of single-component monofilament heat-fusible yarns. A receiving volume is arranged between the first layer 410 and the second layer 420 and is configured to receive functional elements such as shock-absorbing elements or hardening elements. In this specific example, the receiving volume of the second additional portion 20(B) is empty. The two layers 410 and 420 allow for a localized increase in the thickness of the second additional textile section (B) 400. Once the at least partially melted hot-melt yarn has thus formed the hot-melt textile section, the second additional textile section (B) 400 performs the function of a toe-puff.

[0215] Figure 5 and Figure 6A main textile element 100 is presented, positioned on a rigid prefabricated member 10 (for illustrative purposes only) and connected to a sole element 500 (outsole 510 in this specific example), the sole element specifically including a plurality of studs 520 protruding from the outer surface 515 of the outsole 510. A sole portion 205 of the main textile boot 200 is disposed abutting against the inner surface 516 of the sole element 500, and a first additional textile portion (A) 300 partially wraps around the peripheral edge 517 of the sole element 500. The peripheral edge 517 extends between the inner surface 516 and the outer surface 515 of the sole element 500 and is preferably substantially vertical. Specifically, the first additional textile portion (A) 300 includes an intermediate textile portion 320 and a wrap portion 330. The intermediate textile portion is disposed between the sole portion 205 of the main textile boot 200 and the inner surface 516 of the sole element 500. The wrap portion is located in an extension of the intermediate portion 320 and partially covers the peripheral edge 517 and the outer surface 515 of the sole element. Therefore, the joint 20 between the main textile boot 200 and the sole element 500 is partially and locally reinforced in the front portion 220 of the main textile boot 200, and in this specific example, partially and locally reinforced in the outer portion 212 and the inner portion 210. Thus, the joint 20 includes multiple textile thicknesses: the first textile layer 410 and the second textile layer 420 of the second additional textile portion (B) 400, the main textile boot 200, and the first textile layer 340 and the second textile layer 350 of the first additional textile portion (A) 300. Therefore, the joint 20 between the main textile boot 200 and the sole element 500 is reinforced, particularly by the first additional textile portion (A) 300. When at least partially heat-fusible yarn is melted, the anti-delamination properties of the main textile boot 200 of the sole element 500, as well as the abrasion resistance and durability of the main textile boot 200, are improved.

[0216] It can also be done by special means Figures 7 to 10 The auxiliary textile boot 600 shown in the image covers the main textile element 100 and the sole element 500. For example... Figure 7 As shown, the auxiliary textile boot 600 is preferably disposed around the main textile element 100 which is connected to the sole element 500. Figure 8 An auxiliary textile boot 600 is presented slightly folded over itself to display the main textile element 100, which is set on the prefabricated part 10 and connected to the sole element 500.

[0217] The auxiliary textile boot 600 includes a rear portion 605, an inner portion 610, an outer portion 615, a front portion 620, and a sole portion 625.

[0218] The auxiliary textile boot 600 includes in its sole portion 625 Figure 10The presented receiving area 626 (in particular the through opening) receives the studs 520 protruding from the outer surface of the sole element 500.

[0219] The auxiliary textile boot 600 has a hollow, elongated shape and includes a first through-hole 630 and a second through-hole 640. In this specific example, the second through-hole 640 substantially overlaps with the second foot-introducing through-hole 225 of the main textile boot 200. The first through-hole 630 expands into the internal volume of the auxiliary textile boot 600, but its outer edges 632 and 634 are attached, for example, by stitching. Thus, the first opening 630 of the auxiliary textile boot 600 is closed, while the first opening 235 of the main textile boot 200 remains open. The main boot 200 and the auxiliary boot 600 are preferably knitted on a small-diameter circular knitting machine, so that their generally elongated and hollow shapes each include a first through-hole and a second through-hole. The second through-holes 225 and 640 substantially overlap and correspond to the openings for introducing the foot into the footwear 700. The first through-hole 235 of the main textile boot 200 remains open because a first additional textile portion (A) protrudes from it. The circular arrangement of the second through opening 235, which remains open, facilitates the partial wrapping of the essentially circular periphery 517 of the front of the sole element 500.

[0220] The auxiliary textile boot 600 includes an elastic annular region 650 that borders a second through-hole 640 for introducing the foot. Preferably, the elastic annular region 650 does not include heat-fused yarns.

[0221] An assembly comprising a main textile element 100 cooperating with a sole element 500, an auxiliary textile boot 200, and optional one or more reinforcing and / or hardening and / or aesthetic elements is partially disposed in a mold. The preform 10 is replaced by an inflatable sheath disposed within the foot-receiving volume of the main textile boot 200. The mold components are closed. The inflatable sheath is gradually inflated to press the textile portion of the assembly against the inner wall of the mold and against the inflatable sheath. The assembly is then heated to a temperature greater than or equal to one or more melting temperatures of at least partially heat-fusible yarns to achieve melting of the heat-fusible yarns and the formation of the heat-fusible textile portion. Upon exiting the hot-pressing step, the temporary elastic textile element 110 is separated from the main textile boot 200, specifically by cutting it off. The temperature conditions and inflation pressure are determined by those skilled in the art based on the nature of the yarns implemented and may depend on one or more of the implemented functional elements.

[0222] exist Figure 11The obtained footwear 700 is presented, and the obtained footwear 700 includes an upper 710 comprising a textile element 100 and a thermoformed auxiliary textile boot 200. A sole element 500 is disposed between the main textile boot 200 and the auxiliary textile boot 600. In this specific example, the sole element is a molded part, for example, a molded part of an abrasion-resistant elastomer. A first additional textile portion (A) 300 and a second additional textile portion (B) 400 respectively reinforce the joint between the main textile boot 200 and the sole element 500 and the front portion 220 of the upper 710 by forming a hard cap. Studs 520 protrude through the sole portion 625 of the auxiliary textile boot 600 of the upper 710. The footwear 700 includes a longitudinal axis extending substantially between the rear and front of the article. The footwear 700 also includes a transverse axis, which is substantially perpendicular to the longitudinal axis in particular.

[0223] In one embodiment, the sole portion 625 of the auxiliary textile boot 600 is composed of / includes a heat-fused textile, particularly a transparent / opaque portion that makes the sole portion 205 of the main textile boot 200 visible. The heat-fused portion is preferably disposed on the sole portion 625 facing the first through-hole 235 of the main textile boot 200.

[0224] Advantageously, the footwear 700 has a weight of approximately 160g.

[0225] The upper 710 of footwear 700 may also exclude the auxiliary textile boot 600. Therefore, the sole element 500 will be almost entirely visible. Then, the first additional textile section (A) 300 ensures individual resistance to partial delamination.

[0226] Figure 12 A second example of a main textile element 800 according to the invention, disposed on a rigid prefabricated member 11, is presented for illustrative purposes. The main textile element 800 is described below essentially in accordance with its differences from the main textile element 300. The main textile element 800 includes a main textile boot 860, which includes a sole portion 865, a rear portion 870, a front portion 875, an outer portion 880, and an inner portion. The main textile element 800 also includes temporary and therefore removable textile elements 810, a first additional textile portion (A) 850, a third additional textile portion (C) 900, and a fourth additional textile portion (D) 950, which are folded into the internal volume of the main textile boot 860. The main textile boot 860 includes a second through-opening 885 for introducing a foot into the internal volume of the main textile boot 860. The second through-opening 885 is partially bordered by a generally C-shaped region 890, which specifically includes n p-ribbed needles, for example, with 1 1. Ribbed pattern.

[0227] The main textile element 800 includes a second textile bonding portion 895 in an extension of region 890, which specifically includes / is composed of at least partially heat-fusible yarn. Preferably, a third additional textile portion (C) 900 is in an extension of the second textile bonding portion 895 and has a generally C-shape opening toward the front portion 875 of the main textile boot 860. The third portion (C) 900 includes a substantially overlapping first textile layer 862 and a second textile layer 864 and a receiving volume 863 disposed between the first layer 862 and the second layer 864. Preferably, the first textile layer 862 includes at least 50% by mass of at least partially heat-fusible yarn equivalent to the total mass of the first textile layer 862, particularly at most 20% by mass of at least partially heat-fusible yarn. Preferably, the second textile layer 864 comprises at least 80% by weight of at least partially heat-fusible yarn, specifically at least 95% by weight of at least partially heat-fusible yarn, corresponding to the total mass of the second textile layer 864. Preferably, the second joining portion 895, the third portion (C) 900, and the main textile boot 860 are uniformly knitted. Therefore, the main textile element 800 is preferably a uniformly knitted structure.

[0228] The second textile bonding portion 895 extends from the edge of the second through opening 885 of the main textile boot 860. In particular, the second textile bonding portion 890 includes a first layer and a second layer, which are substantially overlapped and connected to the first layer 862 and the second layer 864 of the third portion (C) 900.

[0229] The main textile element 800 also includes a fourth additional textile portion (D) 950 connected to the second through opening 885, and in particular, the fourth additional textile portion (D) is fully or partially knitted to the edge of the second through opening 885.

Preferably, each of the first textile layer 952 and the second textile layer 954 comprises one or more heat-fusible yarns, which represent at least 80% by mass, and in particular at least 95%, of the total mass of the fourth additional textile portion (D) 950. Prior to the hot-pressing step, as... Figure 12As presented, the third additional textile portion (C) 900 and the fourth additional textile portion (D) 950, along with the second joining portion 895, are folded into the internal volume of the main textile boot 860. Therefore, the fourth additional textile portion (D) 950 is partially disposed between the third additional textile portion (C) 900 and the inner surface of the rear portion 870 of the main textile boot 860. Thus, the second textile layer 864 of the third additional portion (C) 900 rests against the first textile layer 952 of the fourth additional portion (D) 950. The length of the fourth textile portion (D) 950 is determined to preferably cover the entire height of the rear portion 870 and partially cover both the outer and inner portions.

[0231] Preferably, the containment volume 863 of the third part (C) comprises an elastically deformable element, such as foam, and the containment volume of the fourth part (D) remains empty.

[0232] Following the hot pressing step, the third and fourth additional textile portions preferably form a post-cured part. During hot pressing, the substantially heat-melted second textile bonding region 895 absorbs any movement of the folded and overlapped third and fourth textile portions 900 and 950.

[0233] Preferably, and generally, in this document, the first additional textile portion (A) and / or the second additional textile portion (B) and / or the third additional textile portion (C) and / or the fourth additional textile portion (D) (each) are in the form of a tube, in particular having one or two open ends connected to all or part of the edge textile (especially knitted) of the first through opening or the second through opening of the main textile boot.
