Description

[0001] This application is a divisional application of the invention patent application with the application date of September 21, 2018, the priority date of September 27, 2017, the application number of

[0002] 201880062746.1, and the invention title of "Lining for Clothing, Footwear or Accessories".

[0003] The present invention relates to a lining for use in clothing, footwear and accessories for clothing, such as gloves, backpacks and bags.

[0004] The present invention also relates to clothing and footwear provided with said lining.

[0005] Clothing worn by a person, including footwear and clothing, interacts with the human body, for example by exerting contact pressure at the points where the clothing contacts the human body. The pressure is generated, for example, due to the weight of the clothing itself and the tension of the fabrics that generally make them up.

[0006] The clothing contacts the user's body more or less continuously: for example, at the top of the shoulders, the contact is substantially continuous and constant because the weight of the clothing itself pushes the clothing down to the position where it contacts the user's body.

[0007] The anatomical structure of the human body causes a hollow to be formed along the spine, for example, relative to the back area directly below the top of the shoulders and at the lateral part of the spine. This hollow extends to the sides. This causes the clothing to adhere more to the body in the back area directly below the top of the shoulders and at the lateral part of the spine, and to contact the user's body less tightly at the spine.

[0008] The higher the contact, the higher the contact pressure. For example, because the fabric is heavier, or because the tension on the yarns making up the fabric is greater.

[0009] For example, consider a coat or jacket. The contact pressure on the top of the shoulders is mainly determined by the weight of the clothing itself, while in the back area directly below the top of the shoulders and at the lateral part of the spine, the contact pressure is mainly determined by the tension of the fabric.

[0010] Figure 1 The differences in contact pressure in various regions of the back of a person in motion are schematically shown.

[0011] In the spinal region represented by the letter A, the contact pressure is substantially zero.

[0012] In the region below the top of the shoulders and at the lateral part of the spine A, represented by the letter B, the contact pressure reaches a value of 0.7 kPa.

[0013] In the lateral region represented by the reference letter C, the contact pressure is even higher, up to a value of 1.2 kPa.

[0014] In the lumbar region, denoted by the letter D, the pressure is again substantially zero.

[0015] In the region of the sacrococcygeal joint, the pressure is substantially zero.

[0016] In the central region, denoted by the letter E, the contact pressure is substantially zero, but rises to 0.7 kPa in the two outer regions F.

[0017] The human body itself also exerts pressure on the clothing. This pressure is caused, for example, by the weight of the body or its movement.

[0018] Therefore, the clothing must be suitable for being worn effectively and comfortably on the human body, for example, not collapsing under the action of the weight of the body itself, or not sagging under the action of the weight of the clothing itself, or not overly compressing some regions either.

[0019] It is well known that the human body has regions that are more or less rich in sweat glands, and the sweat produced by these sweat glands is suitable for cooling the body through evaporation due to the heat of the human body.

[0020] Figure 2a and 2b are respectively schematic diagrams of the distribution of the sweating regions in the front view and the rear view of the human body.

[0021] The following table gives the values of sweating in various regions of the human body.

[0022]

[0023] To maintain effective thermoregulation of the human body, it is important that the sweat in the vapor phase moves away from the human body; this is to avoid condensation inside the clothing, resulting in a feeling of dampness and discomfort.

[0024] The above requirements exist simultaneously in various regions of the human body, but to different degrees.

[0025] In particular, these requirements occur on the shoulders, in the back region, in the spinal region, on the sides, and on the feet.

[0026] Therefore, it is necessary to provide a piece of clothing in which the part in contact with the human body, usually the lining of a coat or footwear, can meet these requirements in various ways.

[0027] Depending on the region of the foot considered, different values of contact pressure also occur between the inner surface or lining of the shoe upper and the foot.

[0028] It is well known that in static conditions, the foot has three resting regions: the heel rests on the calcaneus, the anterolateral side rests on the head of the fifth metatarsal, and the anteromedial side rests on the head of the first metatarsal and the sesamoid bones.

[0029] The three rest areas define the presence of three arches:

[0030] – The anterior arch formed by the five metatarsal heads;

[0031] – The lateral longitudinal arch between the calcaneus and the fifth metatarsal head;

[0032] – The medial longitudinal arch formed by the heel, the talus, the navicular bone, the first cuneiform bone, and the first metatarsal bone; the navicular bone is at the apex of the arch.

[0033] During movement, the rest of the foot is divided into three phases:

[0034] – The first phase: Contact with the ground using the posterior area of the heel, the corner (weight on the outer side of the foot when walking, taligrade) time;

[0035] – The second phase: At the lateral longitudinal arch, rest on the area of the heel, the area of the front foot, and the lateral edge of the foot, the plantigrade (sole of the foot on the ground when walking) time;

[0036] – The third phase: Rest only on the front foot, gradually releasing from the outside to the inside on the metatarsal heads, the digitigrade time.

[0037] This means that during the rest phase and during movement, the rest of the foot occurs to a large extent on the lateral section of the sole, while the medial section of the middle area of the foot only participates to a minimal extent in the rest of the foot.

[0038] For these reasons, the support and ventilation requirements are different.

[0039] Currently, it is a widespread practice to provide clothing, footwear, or accessories that allow effective thermal regulation of the user's body.

[0040] For example, WO2015193385A1 filed in the name of the same applicant contains teachings for providing a ventilated shoe, wherein the upper assembly includes an inner lining, which in turn is at least partially constituted by a first element forming at least one gap that separates the user's foot from the outer upper, and has preferential sweat channels through which sweat moves from the user's foot towards the outer edge of the shoe upper. The shoes described in the cited document also include a vapor-permeable insole that is at least peripherally connected to the inner lining, which forms at least one gap for separating the user's foot from the sole. The combination of the channeled lining and the insole promotes ventilation around the foot.

[0041] However, this prior art has some drawbacks.

[0042] All the channels of the lining have a substantially constant width and a substantially parallel arrangement, which are directed from the lower part of the shoe towards the upper part. However, in this arrangement, the different requirements of the various areas of the foot in terms of sweating are not taken into account: in fact, it is well known that in the areas with a greater blood supply, more heat is generated, and more sweat is produced in the areas with more sweat glands.

[0043] Therefore, these areas require a greater ventilation volume to cool the foot and carry the sweat away from the foot.

[0044] In addition, the insole of the shoe only has a gap that separates the user's foot from the sole, so there is no area that provides a more stable placement of the foot on which the user's weight rests, such as the heel.

[0045] EP 1723863A1 contains teachings for providing a shoe that includes a lining composed of a series of parallel hollow channels and a perforated insole, a first series of spaced-apart spacer elements, and a lower insole.

[0046] There are also some disadvantages in this prior art.

[0047] In such a shoe, air is not directed into the space between one channel and another at any height, but only inside the channels starting from the lower part of the foot. Therefore, most of the lining is still excluded from the extraction of moist and warm air.

[0048] US2016 / 0213090 is also well known, which teaches providing a ventilation system incorporated in a shoe that includes a ventilated midsole and at least one ventilated fin. The ventilated midsole is inserted into the upper, and at least one ventilated fin is integrally connected and forms a channel for the air inside the shoe.

[0049] In addition to requiring additional components, namely fins, compared to traditional shoes, this embodiment does not define areas with different load-bearing capacities according to the load exerted by the user's foot, and does not provide a shape of the air channels that is proportional to the different sweating degrees of different areas of the foot.

[0050] EP1367913B1 contains teachings for implementing a fabric that includes a porous layer and has a porosity in the longitudinal direction of the layer. The fabric can have a surface that is impermeable to fluids such as air passing through the porous layer and channels.

[0051] However, there are some aspects that can be improved.

[0052] Air cannot pass through the fabric in the lateral direction, thus being disadvantageous for ventilation. Moreover, except in restricted areas, the channels do not allow for optimizing the ventilation of the user's body by following the anatomical shape of the user.

[0053] EP1266584B1, filed in the name of the same applicant, claims a multi-layer fabric comprising an inner layer and an outer layer, both made of a material capable of dissipating sweat, and an intermediate layer made of a material capable of transferring the condensed sweat to the outside of the clothing.

[0054] However, this solution has the following drawbacks: the inner layer is hydrophilic, thus not allowing for a continuous and linear outward discharge of vapors, which results in condensation inside the clothing. Moreover, there is no channel system allowing the vapors to be evacuated along the fabric, but only through the fabric.

[0055] To overcome the said drawbacks, the same applicant has filed EP2007235B1, which claims a multi-layer fabric comprising: a first hydrophobic and vapor-permeable layer, which is arranged facing the user in the form of channels and removes sweat from the user, both in the liquid and vapor phases; a second intermediate hydrophobic layer, which transfers the sweat in the liquid phase from the first layer on the inside to the third layer on the outside and transfers the sweat in the vapor phase from the first layer on the inside to the outside; a third outer hydrophilic layer, which promotes the outward evaporation of sweat.

[0056] The fabric is processed on a warp and weft loom: the filaments of the second layer are woven inside the strips of the first and third layers; however, the channels have a direction that is substantially parallel to each other and do not allow for regional differentiation according to different requirements.

[0057] The object of the present invention is to provide a lining that can improve the prior art in one or more of the above aspects.

[0058] Within this object, the aim of the present invention is to provide a lining that can ensure better handling of sweat in the vapor and liquid phases relative to known linings.

[0059] Another object of the present invention is to provide a lining that can achieve such footwear or clothing in which the lining is used to ventilate around the user's body for a proper exchange of heat and water vapor between the microclimate generated inside the footwear or clothing and the external microclimate, even if the external material of the footwear or clothing is not vapor-permeable.

[0060] Another aim of the present invention is to provide a lining that produces footwear or clothing in which the lining is used, and which is physiologically more comfortable, allowing for the natural temperature regulation of the user's body and thus allowing it to stay dry for longer.

[0061] Another object of the present invention is to overcome the drawbacks of the background art in a way that replaces any existing solutions.

[0062] Another object of the present invention is to provide a lining for clothing, footwear and accessories that is highly reliable, relatively easy to provide and has a competitive cost.

[0063] This object, and these and other objects that will become more apparent hereinafter, are achieved by a lining for clothing, footwear or accessories according to claim 1, optionally provided with one or more features of the dependent claims.

[0064] Other features and advantages of the present invention will become more apparent from the description of some preferred but non-exclusive embodiments of the lining for clothing, footwear and accessories according to the present invention, which description is shown by way of non-limiting examples in the accompanying drawings, in which:

[0065] In the figures:

[0066] Figure 3 is an exploded view of the interior of a coat provided with a lining according to the present invention;

[0067] Figure 4a and 4b and 4c are each Figure 3 a cross-sectional view of three specific regions of the lining shown;

[0068] Figure 5 is Figure 3 a detail view of the exploded view of;

[0069] Figure 6 is an exploded view of the interior of a shoe provided with a lining according to the present invention.

[0070] Taking into account the above-cited Figure 1 , areas with particularly low contact pressure are suitable for promoting ventilation within the clothing, for example by using a three-dimensional fabric that is advantageously provided with channels created by ribs.

[0071] The channels are designed to guide, by the chimney effect, from bottom to top, for example towards a plurality of openings located in the upper region of the clothing, both the sweat and the warm air in the vapor phase, which are both contained within the clothing.

[0072] Conversely, in areas with higher contact pressure, a larger surface area in contact with the body is required in order to distribute the contact pressure over a larger surface, thus improving the comfort of the user.

[0073] The areas where the contact pressure is greater require a more consistent lining structure, i.e., with a greater density, which can be obtained, for example, by arranging the ribs forming the channels at a smaller mutual distance.

[0074] In particular, the spinal region is alternatively adapted to include a channeled fabric having channels formed by ribs that are spaced further apart from each other. This results in a fabric with a lower density that is sufficient in any case to withstand lower contact pressures.

[0075] The channels are mainly oriented in an upward direction from the lower part of the garment in order to effectively direct sweat and warm air in the vapor phase towards a plurality of outlet openings by the chimney effect, which are advantageously arranged in the upper region of the garment.

[0076] As Figure 1 shown, in the lateral regions at the level of the kidneys, the contact pressure is also significantly low, if not zero.

[0077] These regions are adapted to interface with the channeled fabric, the channels being similar to and mergable with those present in the spinal region. In this way, sweat produced by the glands located near the armpits can also be directed away from the user's body. The sweat condenses and descends along the sides (lateral sides of the body) and, due to the body heat, can evaporate again from there.

[0078] Considering the above-cited Figure 2a and 2b , it is clear that the spinal region is particularly affected by the phenomenon of sweat production; therefore, sufficient ventilation is necessary in this region to ensure effective temperature regulation of the human body.

[0079] Figure 2a and 2b It is also clearly shown that sweating at the shoulders and in the back region, directly below the top of the shoulders and at the sides of the spine, has non-negligible importance. Therefore, in these regions, the requirements for support and sufficient ventilation are combined.

[0080] Taking the above into account, Figure 3 there is shown a lining according to the present invention suitable for an outer garment.

[0081] The lining, which represents the inner layer of the garment, is generally designated by the reference numeral 10.

[0082] The lining includes a plurality of channels alternating with ribs, which at least partially have different widths. The channels have non-linear extensions. In some areas, two or more channels can merge into a common channel.

[0083] The lining 10 includes a right front part 11, a rear part 12, a left front part 13, and two sleeves 14.

[0084] The rear part 12 contacts the user's back, while the right front part 11 and the left front part 13 contact the front of the body.

[0085] The right front part 11 and the left front part 13 are defined relative to the orientation integrated with the user.

[0086] Each of the three parts 11, 12 and 13 includes three fabric areas with different densities.

[0087] Each area has a plurality of ribs 24 spaced apart by channels 25.

[0088] In particular, there are a low-density area 15, a medium-density area 16 and a high-density area 17.

[0089] The different densities are defined based on the mutual distance between the ribs, and thus are based on different channel guiding of the fabric, that is, based on the density of the channels.

[0090] During the assembly of the coat in a manner known per se, the rear part 12, the right front part 11, the left front part 13 and the sleeves 14 are integrated with each other by butting areas with the same density and fusing the channels.

[0091] The channels of the fabric according to the invention follow Figure 3 the arrangement schematically shown in

[0092] The ribs and channels present in the low-density area 15 are close to the spine 18 and close to the front fastener 19 of the clothing and follow a mainly vertical orientation.

[0093] Figure 4a , 4b 4c respectively shows cross-sections at the low-density area 15, the medium-density area 16 and the high-density area 17.

[0094] In the low-density area 15, the directions of the ribs and channels form a gradually increasing angle relative to the spine 18 and the front fastener 19 of the clothing, determining an angle starting from 0° at the spine 18 and at the front fastener 19 of the clothing and tending to 90° at the side of the clothing.

[0095] In this way, the moist air moves from the side of the clothing towards the mainly vertical channels, close to the spine 18 and the front fastener 19 of the clothing, moving along an unobstructed path, especially avoiding passing through the fabric areas with higher density, which would slow down its path and increase the possibility of condensation of sweat in the vapor phase.

[0096] In the medium-density area 16, it is necessary to provide sufficient ventilation and sufficient support for the lining at the same time: therefore, the ribs are closer to each other relative to the low-density area, and the channels have a narrower width.

[0097] In addition, the ribs and channels form an angle included between 30° and 60°, and preferably 40° relative to the spine 18

[0098] an angle between 0° and 50°.

[0099] Such an orientation allows the humid air to follow the shortest path, thus intercepting the channels close to the spine 18 and the front clasp 19.

[0100] Advantageously, the amplitude of said angle is determined according to the vertical extension (quantity) of the garment, i.e.: as the size of the garment increases, the vertical extension of the garment increases and the amplitude of the channel angle decreases.

[0101] In the high-density area 17, the channels can follow a path for removing the wet and warm air from the body, which is shorter than those characterizing the medium-density area 16 and the low-density area 15.

[0102] In fact, the high-density area 17 is located at the top of the shoulder, i.e., in the vertex area of the body, where there are outlet openings not shown in the drawings.

[0103] In the high-density area 17, the channels at least partially intercept the channels of the medium-density area 16 in order to reduce the interruption of the flow of the wet and warm air.

[0104] In particular, the channels in the high-density area 17 maintain a substantially uniform inclination in order to avoid a sudden reorientation of the flow of the wet and warm air and to control the risk of condensation of the sweat in the vapor phase.

[0105] As in the medium-density area 16, in the high-density area 17, the channels also follow (along) an angle included between 30° and 60°, and preferably between 40° and 50°, with respect to the spine 18 and the front panel (front clasp) 19.

[0106] The ribs and the channels are preferably dimensioned such that the high-density area 17 has ribs that are closer to each other, and the average width of the channels is smaller than that of the medium-density area 16: in these areas 17, the number of channels per unit surface is greater.

[0107] For these reasons, referring to Figure 5 , in order to join the two areas, a plurality of channels 20 in the medium-density area 16 can be merged into the same channel 22 in the high-density area 17, and the ribs 21 in the medium-density area 16 can branch into a plurality of ribs 23 in the high-density area 17.

[0108] The thickness of the ribs is not less than 0.5 mm, and preferably included between 0.5 mm and 4 mm.

[0109] The channels have an average width included between 1 mm and 20 mm between two consecutive ribs.

[0110] Preferably, the channels have a cross-section of less than 15 mm2, thus reducing the risk of liner collapse and not unduly slowing the flow of sweat in the vapor phase, thereby reducing the risk of condensation.

[0111] In particular, in the low-density region 15, the ribs have a width included between 1 and 4 mm, while the channels have a width included between 6 and 20 mm.

[0112] In the medium-density region 16, the ribs have a width included between 2 and 5 mm, while the channels have a width included between 3 and 6 mm.

[0113] In the high-density region 17, the ribs have a width included between 1 and 7 mm, while the channels have a width included between 1 and 3 mm.

[0114] Reference Figure 6 , the liner according to the invention suitable for footwear is generally denoted by the reference numeral 110.

[0115] It includes a central part 111 and two lateral parts 112a and 112b, the central part 111 corresponding to the area of the foot at the interface with the sole, and the two lateral parts 112a and 112b corresponding to the planar extensions of the surfaces of the foot other than the surface of the sole 111.

[0116] These three parts can be provided separately by joining a plurality of pieces and then connecting them.

[0117] In particular, the liner 110 includes a preferential passage located in a very precise area defined by the channels 114 to allow sweat in the vapor phase to pass through, and this preferential passage is delimited by the ribs 113.

[0118] In the context of this patent, the term "preferential" has the meaning of "being preferentially subjected to" for the part of the sweat in the vapor phase. When it encounters a material having an area with passages and an area without passages, it is attracted by the channels and is "preferred" to them. Thus, it is preferentially subjected to the area containing the channels as compared to the area lacking passages.

[0119] The central part 111 includes six regions defined by the different densities of the liner.

[0120] Specifically, the central part 111 includes: a heel region 115, a latero-medial middle region 116 corresponding to the projection 120 of the lateral longitudinal arch of the foot, an area 121 of the heads of the metatarsals, a medio-medial middle region 119 included between the heel 115 and the heads of the metatarsals 121, a distal forefoot region 118 corresponding to the distal surface, and an intermediate forefoot region 117 included between the area 121 of the heads of the metatarsals and the distal region 118.

[0121] The ribs arranged in the outer lateral middle region 116 follow the resting behavior of the foot in the part corresponding to the projection 120 of the lateral longitudinal arch, that is, they follow the projection of the lateral longitudinal arch on the planar extension of the sole of the foot. In this way, optimal support is provided.

[0122] The medial lateral middle region 119 requires less support. Therefore, the ribs are arranged at a greater mutual distance, defining a wider passage, and the surface of the region relative to the projection 120 of the lateral longitudinal arch is conducive to greater ventilation, in which the need to support the foot is dominant relative to the need for ventilation.

[0123] The passage in the medial lateral middle region 119 extends substantially perpendicular to the longitudinal direction of the foot.

[0124] The longitudinal direction of the foot is defined as the direction connecting the front foot to the heel.

[0125] The region of the head of the metatarsal bone 121, which is also involved in the resting of the foot, requires support similar to that of the region of the projection 120 of the lateral longitudinal arch and shares the same rib and passage arrangement as this region.

[0126] The foot is mainly lifted relative to the ground at the middle front foot region 117.

[0127] In the middle front foot region 117, the sweat glands of the foot are also particularly abundant. Therefore, the need for sufficient ventilation is dominant relative to the need for support.

[0128] The ribs in this part are arranged at a greater mutual distance than in the outer lateral middle region 116, forming a wider passage and thus promoting effective ventilation.

[0129] Advantageously, in the middle front foot region 117, the ribs and the corresponding passages are arranged in the transverse direction relative to the foot, thus promoting the removal of sweat and heat in the vapor phase along the shortest path.

[0130] Advantageously, the middle front foot region 117 includes a lobular part 117a protruding towards the distal front foot region 118. In particular, this part 117a preferably corresponds to the region included between the first toe and the third toe of the foot.

[0131] During the resting phase and during movement, the weight of the body is mainly released in the region 115 on the calcaneus, which is the largest bone of the tarsus.

[0132] The sole surface of the foot at the calcaneus is also substantially free of sweat glands.

[0133] For these reasons, in the heel region 115, the need for foot support takes precedence over the need for sufficient ventilation.

[0134] In the heel region 115, the lining has no ribs and channels.

[0135] A portion of the plantar surface of the foot in the distal region 118 of the forefoot is affected by the propulsion phase of the foot,

[0136] and thus requires sufficient support to ensure effective propulsion.

[0137] Therefore, the need for foot support in the distal region 118 is dominant.

[0138] The distal region 118 has a density and arrangement of ribs and channels similar to those of the ribs and channels arranged in the lateral mid-region 116.

[0139] In particular, the channels are preferably oriented along the longitudinal direction of the foot.

[0140] The lateral mid-region 116 and the distal region 118 are high-density regions.

[0141] In the high-density regions, the ribs have a width ranging from 1 mm to 7 mm, while the channels have a width ranging from 1 to 3 mm.

[0142] The medial mid-region 119 is a medium-density region.

[0143] In the medium-density region, the ribs have a width ranging from 2 mm to 5 mm, while the channels have a width ranging from 3 mm to 6 mm.

[0144] The middle region 117 of the forefoot is a low-density region.

[0145] In the low-density region, the ribs have a width ranging from 1 mm to 4 mm, while the channels have a width ranging from 6 mm to 20 mm.

[0146] Advantageously, if increased ventilation is required, for example in footwear intended for more intensive use, additional channels 114a can be arranged in a direction substantially transverse to the existing channels 114, for example in the lateral mid-region 116 where they are arranged in a direction transverse to the foot.

[0147] For the same purpose, the lateral additional channels 114a can also be advantageously arranged in the distal region 118.

[0148] The lateral portions 112a and 112b each have a plurality of channels 114 that extend in a direction from respective edges 122a and 122b for interfacing with the sole 111 to respective opposite edges 123a and 123b.

[0149] In the central region closer to the foot, the ribs are arranged at a greater mutual distance to form wider channels for promoting effective ventilation.

[0150] Conversely, in the regions closest to the heel and toes that are more susceptible to wear and pressure, and in the regions where the need for foot control during movement is dominant, the ribs are closer and the width of the channels is smaller.

[0151] The channels of the lateral portions 112a and 112b extend such that interruptions and crossings are minimized in order to reduce the points of stagnation and / or interruption that could cause condensation of the sweat flow in the vapor phase.

[0152] As the distance from the edges 122a and 122b increases and approaches the edges 123a and 123b, the width of the channels in the lateral portions 112a and 112b decreases.

[0153] Advantageously, the channels have a larger cross-section at the edges 122a and 122b and a smaller cross-section near the edges 123a and 123b.

[0154] This difference in cross-section is adapted to generate an acceleration of the sweat and warm air in the vapor phase, which rises naturally towards the upper part of the footwear, thus facilitating their departure from the upper part of the footwear.

[0155] The lining 110 according to the invention can be used in footwear, where the central part can be used as a footrest surface without using an insole.

[0156] In this way, a reduction in the cost of the footwear is achieved.

[0157] In this particular configuration, the lining can have regions where the fabric has different thicknesses, thus following the anatomy of the foot and, in particular, the geometry of the medial longitudinal arch and the lateral longitudinal arch of the foot. In this case, the thickness of the fabric is greater, for example, at the medial longitudinal arch relative to the lateral longitudinal arch.

[0158] Each part of the lining according to the invention is advantageously formed from a three-dimensional fabric.

[0159] The term "three-dimensional fabric" is generally understood to mean a single fabric in which the constituent fibers are arranged in a mutually perpendicular planar relationship.

[0160] From a production process point of view, in 3D type weaving, the groups of fibers X and Y are interwoven with the rows and columns of the axial fibers Z. The expression "groups of fibers X and Y" should be understood to refer to the horizontal and vertical weft yarn groups. The expression "fiber Z" should be understood to refer to the multi-layer warp yarn groups.

[0161] Three-dimensional fabrics can also be obtained by a 2D type weaving process.

[0162] Three-dimensional fabrics can also be obtained by knitting on a flat knitting machine or a circular knitting machine.

[0163] The ribs and channels can be obtained directly during the process for forming the fabric, or subsequently, for example, starting from a fabric that is completely or partially without channels, by means of a thermoforming or high-frequency heat-sealing process.

[0164] If the ribs and channels are obtained directly during the process for forming the fabric, due to the necessary discretization of the bending profile, they can have a serrated appearance, so that they can be replicated by means of a weaving process.

[0165] Advantageously, the three-dimensional fabric can be composed of monofilament yarns.

[0166] Advantageously, the three-dimensional fabric can include multiple layers: for example, a hydrophobic layer facing the user's body and a hydrophilic layer arranged oppositely.

[0167] Advantageously, a raising process can be provided to give a softer and more comfortable texture to the surface of the layer facing the user's body.

[0168] Synthetic yarns such as polyester, polypropylene or polyamide, or natural yarns such as wool, cotton, linen can be used.

[0169] Furthermore, the possibility of obtaining channels directly on the fabric constituting the lining and / or insole allows eliminating the recourse to channeled inserts made, for example, of a polymer foam co-molded on the fabric or a laminate containing ethylene vinyl acetate (EVA) or polyurethane (PU), thus reducing the complexity and cost of the footwear.

[0170] In practice, it has been found that the present invention achieves the intended purposes and objects, providing a lining for clothing, footwear and accessories, which includes a fabric having a plurality of channels alternating with ribs, characterized in that said channels at least partially have a differentiated (different) width.

[0171] The present invention thus conceived can be subject to various modifications and variations, all of which are within the scope of the appended claims; all details can also be replaced by other technically equivalent elements.

[0172] In practice, the materials used can be any materials according to requirements and the state of the art, provided that they are compatible with the specific use, as well as with the shape and dimensions which vary according to circumstances.

[0173] The disclosure of Italian Patent Application No. 102017000107834, from which this application claims priority, is incorporated herein by reference.

[0174] In the case where reference signs are attached to the technical features mentioned in any claim, these reference signs are included only for the purpose of increasing the intelligibility of the claim and, accordingly, they have no limiting effect on the interpretation of each element which is identified by way of example by these reference signs.
