Description

[Technical field]

[0001] The present disclosure relates to resizable fabrics, and in particular to fabrics that can be repeatedly resized and resized to any size within a range of sizes.

[0002] The present disclosure further relates to wearable articles, such as garments, harnesses, and the like, that can be resized using such resizable fabrics.

[0003] The present disclosure also relates to a method for sizing fabric.

[0004] The present disclosure further relates to footwear and liners for footwear that can be resized and / or fine-tuned with respect to size. [Background technology]

[0005] There are many applications where it may be desirable to be able to resize an article made from fabric to achieve an optimal fit on the wearer or to achieve a one-size-fits-all article.

[0006] For example, various garments such as suits, jackets, pants, etc., need to be produced in multiple sizes. In addition, they often may need to be adjusted by a tailor to fit the wearer.

[0007] Some articles may be provided with size adjustment mechanisms such as straps and buckles, hook and loop fasteners, elastic insets, cuffs or sleeves, etc.

[0008] Improved sizing devices are needed, especially for expensive wearable articles such as cooling vests, stab and bullet resistant vests, equipment harnesses, and similar equipment that must fit perfectly to the user in order to provide optimal function.

[0009] For example, US20070042660A1, GB2441589A, and EP3511454A1 disclose various uses of shape memory alloys integrated into fabrics to provide fabrics that can change size.

[0010] However, such solutions are adjustable between a small number of discrete positions, which limits their usefulness.

[0011] There is a need for improved solutions for altering the size of clothing and other wearable articles. Summary of the Invention

[0012] It is an object of the present disclosure to provide improved concepts for adjustable-size garments and other wearable articles. One particular object is to provide concepts that allow for improved one-size-fits-all articles, or at least "near-one-size" articles.

[0013] The invention is defined by the accompanying independent claims, and embodiments are set out in the dependent claims, the following description and the accompanying drawings.

[0014] According to a first aspect, there is provided a sizeable woven fabric comprising a first set of yarns each formed of a heat shrinkable polymeric material and at least one conductive yarn formed of an electrically conductive material, the first set of yarns extending substantially parallel to one another and the conductive yarn extending substantially across the first set of yarns.

[0015] The term "substantially parallel" means parallel except for minor variations.

[0016] The term "substantially across" means across except in the area where the conductive yarn bends.

[0017] A heat shrinkable polymeric material may be a polymeric material that has been treated during production to provide an original state, for example by crosslinking, typically by ionizing radiation, and then stretched while heated above its crystalline melting point to create an elongated state, and then rapidly cooled. The stretched heat shrinkable polymeric material has the ability to return to its original state when heated above its crystalline melting point.

[0018] Heat shrinkable polymeric materials are known per se.

[0019] Thus, unlike shape memory polymers that can deform between two or three different configurations, heat shrink polymers can assume any configuration between their original state and the elongated state.

[0020] Thus, by using heat shrink polymers, it is possible to provide a size adjustable fabric that can be adjusted across a range of sizes, as well as to provide a size adjustable fabric that can be repeatedly resized by either shrinking or stretching the fabric.

[0021] A combination of yarns formed from one or more heat shrinkable polymeric materials can be heated by the conductive yarns. By using the heat shrinkable material, the length of a first set of yarns can be expanded or contracted by heating by the conductive yarns while selectively applying a load to the first set of yarns. The first set of yarns can form a set of warp yarns and the conductive yarns can form a set of weft yarns.

[0022] The conductive yarn may extend, excluding its turns, at an angle of approximately 80-100 degrees to the first set of yarns.

[0023] Heat shrinkable polymeric materials can be made from a range of polymeric materials including polyolefins, polyesters, polyvinyl chloride (PVC), fluorocarbon-based synthetic rubbers (such as Viton® by The Chemours Company), polychloroprene rubber, polytetrafluoroethylene (PTFE), elastomers, fluorinated ethylene propylene (FEP), and polyvinylidene fluoride (PVDF).

[0024] The heat shrinkable polymeric material may be a polymeric material that has been crosslinked and then stretched.

[0025] Such cross-linking can be achieved through irradiation.

[0026] As a non-limiting example, heat shrinkable polyolefins may operate at shrink temperatures of 90-120°C and extension temperatures of 120-145°C.

[0027] As a further non-limiting example, heat shrinkable polyvinyl chloride may be operated at a shrink temperature of about 100°C and an extension temperature of about 120°C.

[0028] As a further non-limiting example, heat shrink PVDF may be operated at a shrink temperature of about 170°C and an elongation temperature of about 210°C.

[0029] The fabric may further comprise at least one additional non-conductive yarn, which extends mostly parallel to the conductive yarn.

[0030] The conductive yarn may extend across the entire first set of yarns.

[0031] As an alternative, the conductive yarn may extend across less than all of the yarns in the first set of yarns, at least in a section along the length of the yarns in the first set.

[0032] The threads of the first set of threads may be of at least two different lengths.

[0033] The fabric may further include at least one elongation-limiting yarn that extends parallel to the first set of yarns, the elongation-limiting yarn exhibiting a curved portion between crossing portions of the conductive yarn when the first set of yarns is in a contracted state.

[0034] As an alternative, the conductive yarns may form the warp yarns and the first set of yarns may form the weft yarns.

[0035] According to a second aspect, there is provided a wearable article, comprising: A first flexible, fixed-size fabric part, a second flexible, fixed-size fabric part, and a patch formed of the size-adjustable fabric according to any one of claims 1 to 11, the patch being disposed between and connecting the first flexible, fixed-size fabric part and the second flexible, fixed-size fabric part, wherein the first set of yarns is at a larger angle (a t ) extending to an edge of at least one of the first and second flexible, fixed size fabric portions.

[0036] According to a third aspect, there is provided a method of expanding the size of a fabric as disclosed above, comprising: supplying an electric current through the conductive yarns for a time sufficient to heat the first set of yarns to an elongation temperature, the elongation temperature being within a range of from the melting temperature of the heat shrinkable polymeric material to the melting temperature plus 200 degrees, applying a tensile force in a direction substantially parallel to the extent of the first set of yarns when the elongation temperature is reached, stretching the fabric in that direction to a first desired degree of elongation, preferably 110-250%, while maintaining the elongation temperature, and then allowing the stretched fabric to cool to a temperature at least 50 degrees below the melting temperature of the heat shrinkable polymeric material.

[0037] The method may further comprise supplying an electric current through the conductive yarn for a time sufficient to heat the first set of yarns to a shrinkage temperature, the shrinkage temperature being within a range of 50 degrees minus a melting temperature of the heat shrinkable polymeric material to 10 degrees plus the melting temperature, allowing the fabric to shrink while maintaining the shrinkage temperature, and then allowing the shrunken fabric to cool to a temperature at least 50 degrees below the melting temperature of the heat shrinkable polymeric material; supplying an electric current through the conductive yarn for a time sufficient to heat the first set of yarns to an elongation temperature, applying a tensile force in a direction substantially parallel to the extent of the first set of yarns when the elongation temperature is reached, and stretching the fabric in that direction to a second desired elongation degree, preferably 110-250%, while maintaining the elongation temperature, and then allowing the stretched fabric to cool to a temperature at least 50 degrees below the melting temperature of the heat shrinkable polymeric material, the second elongation degree being different from the first elongation degree.

[0038] The extension temperature is T m +0 degrees~T m +5 degrees, T m +5 degrees~T m +10 degrees, T m +10 degrees~T m +15 degrees, T m +15 degrees~T m +20 degrees, T m +20 degrees~T m +30 degrees, T m +30 degrees~T m +40 degrees, T m +40 degrees~T m +50 degrees, T m +50 degrees~T m +60 degrees, T m +60 degrees~T m +80 degrees, T m +80 degrees~T m +100 degrees, T m +100 degrees~T m +125 degrees, T m +125 degrees~T m +150 degrees, T m +150 degrees~T m +175 degrees and T m +175 degrees~Tm The temperature may be within a range selected from the group consisting of +200 degrees.

[0039] The shrinkage temperature is T m -50 degrees~T m -40 degrees, T m -40 degrees~T m -30 degrees, T m -30 degrees~T m -20 degrees, T m -20 degrees~T m -10 degrees, T m -10 degrees~T m , T m ~T m +5 degrees and T m +5 degrees~T m The angle may be within a range selected from the group consisting of +10 degrees.

[0040] Thus, the shrink temperature may be slightly above the melting temperature of the heat shrink polymeric material, such as 10 degrees or less, or 5 degrees or less.

[0041] During the contraction step, the first set of yarns should be practically unloaded, i.e. the force applied to the first set of yarns should be lower than the contraction force achievable by the first set of yarns.

[0042] According to a fourth aspect, there is provided a method of reducing the size of a fabric as described above, comprising: supplying an electric current through the conductive yarns for a time sufficient to heat the first set of yarns to a shrinkage temperature, allowing the fabric to shrink while maintaining the shrinkage temperature, and thereafter allowing the stretched fabric to cool to a temperature at least 50 degrees below the crystalline melting point of the heat shrink polymeric material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0056] FIG. 1 is a schematic diagram of a size-adjustable woven fabric 1 according to a first embodiment.

[0057] 1 comprises a first set of yarns, which in the illustrated example form warp yarns 10a-10f that extend substantially parallel to one another in a first direction D1. The fabric further comprises conductive yarns 20, which in the illustrated example form weft yarns in that they extend back and forth across the warp yarns 10a-10f.

[0058] As seen in a first direction D1 and along one of the warp threads 10a to 10f, the weft thread 20 runs alternately above and below the warp thread.

[0059] Similarly, as viewed in the second direction D2 and across the warp threads 10a-10f, the weft threads 20 extend alternately above and below the warp threads.

[0060] The first set of threads 10a-10f are formed from a heat shrinkable polymeric material.

[0061] Heat shrinkable polymeric materials are known per se and can be formed on the basis of various types of polymers or combinations of polymers. Heat shrinkable properties can be achieved in two main ways: by radiation induced crosslinking or by chemically induced crosslinking, with ionizing radiation type crosslinking being the main method currently used.

[0062] Each of the yarns 10a-10f may be formed from one or more filaments.

[0063] The cross section of the thread may be circular, oval, rectangular, or other polygonal, and the major dimension of the cross section may be on the order of 0.1 to 5 mm.

[0064] The conductive yarn 20 is formed from a material that is both electrically conductive and resistive, i.e., a material that heats up when an electric current is passed through it.

[0065] The conductive threads 20 may comprise a metallic material.

[0066] The conductive yarn 20 may be formed from one or more filaments.

[0067] Alternatively, the conductive yarn 20 may be formed from a non-conductive material that is impregnated with a conductive material. For example, a multifilament yarn could be impregnated with a metallic or organic conductive material, including carbon-based materials such as graphite or graphene.

[0068] The conductive yarn 20 may be electrically insulated, for example, by being coated or spun with one or more non-conductive yarns or filaments, however, it is desirable for the conductive yarn to be in sufficient contact with the first set of yarns 10a-10f to allow for thermal conduction from the conductive yarn to the first set of yarns 10a-10f.

[0069] The conductive yarn 20 extends continuously across at least a portion of the fabric 1. A voltage source 30 is connectable to each end of the conductive yarn 20 such that a voltage can be applied to the conductive yarn.

[0070] The controller C may be connectable to the voltage source 30 for controlling the voltage applied by the voltage source 30 .

[0071] The controller C can be configured to control the voltage source to provide an elongation voltage, i.e., a voltage that heats the conductive yarn sufficiently to provide an amount of heat that enables the conductive yarn to reach an elongation temperature that can cause the heat shrinkage to elongate the polymeric material.

[0072] Extension temperature T e is typically the melting temperature T of the polymeric material(s) from which the first set of yarns 10a-10f are formed. mBased on.

[0073] In particular, the elongation temperature T e is typically the melting temperature T of the polymeric material m That's all.

[0074] For some thermoplastic materials, such as polyolefins, the elongation temperature T e can be in the range of 0 to 60 degrees above the melting temperature of the material, preferably 20 to 60 degrees or 20 to 40 degrees above the melting temperature.

[0075] However, for some materials, such as PTFE-type materials, the elongation temperature T e can be in the range of 100-200 degrees above the melting temperature of the material, preferably 150-200 degrees above the melting temperature.

[0076] In various embodiments, the extension temperature T e can be in a range having a lower limit and an upper limit.

[0077] The following list shows the elongation temperature T e The lower and upper limits of the range are listed, and T e The upper limit of the value is T e The lower limit of the range may be selected from the left column, and the upper limit of the range may be selected from the right column. The lower and upper limits of the range may be freely selected from the left and right columns, respectively.

[0078] T e The range (from lower limit to upper limit) may be less than 50 degrees, preferably less than 40 degrees, less than 30 degrees, less than 20 degrees, or less than 10 degrees.

[0079] Extension temperature T e is T m +0 degrees~T m In certain embodiments, the extension temperature T e is T m +0 degrees~T m +5 degrees, T m +5 degrees~T m +10 degrees, Tm +10 degrees~T m +15 degrees, T m +15 degrees~T m +20 degrees, T m +20 degrees~T m +30 degrees, T m +30 degrees~T m +40 degrees, T m +40 degrees~T m +50 degrees, T m +50 degrees~T m +60 degrees, T m +60 degrees~T m +80 degrees, T m +80 degrees~T m +100 degrees, T m +100 degrees~T m +125 degrees, T m +125 degrees~T m +150 degrees, T m +150 degrees~T m +175 degrees and T m +175 degrees~T m The temperature may be within a range selected from the group consisting of +200 degrees.

[0080] Shrinkage temperature T c is typically the melting temperature T of the polymeric material(s) from which the first set of yarns 10a-10f are formed. m Also based on.

[0081] In particular, the shrinkage temperature T c is typically the melting temperature T of the polymeric material m Approximately equal to or lower than

[0082] For some thermoplastic materials, such as polyolefins, the shrinkage temperature T c The shrink temperature T may be in the range of 0 to 40 degrees, preferably 0 to 30 degrees or 0 to 20 degrees, lower than the melting temperature of the material. c Also, the melting temperature is 0 to 10 degrees, preferably the melting temperature T m It can be in the range of 0 to 5 degrees higher than

[0083] However, some materials, such as PTFE-type materials, have a shrinkage temperature Tc can be significantly higher than the melting temperature.

[0084] T c The range (lower limit to upper limit) may be less than 50 degrees, preferably less than 40 degrees, less than 30 degrees, less than 20 degrees, or less than 10 degrees.

[0085] In most cases, the shrink temperature T c is T m +50 degrees~T m In certain embodiments, the shrink temperature T c is T m -50 degrees~T m -40 degrees, T m -40 degrees~T m -30 degrees, T m -30 degrees~T m -20 degrees, T m -20 degrees~T m -10 degrees, T m -10 degrees~T m , T m ~T m +5 degrees and T m +5 degrees~T m The angle may be within a range selected from the group consisting of +10 degrees.

[0086] The controller C can also be configured to control the voltage source to supply a shrink voltage, i.e., a voltage that heats the conductive yarn sufficiently that the conductive yarn provides an amount of heat that enables the heat shrink polymer material to shrink.

[0087] The retraction voltage may be lower than the extension voltage.

[0088] The size of the fabric 1 can be expanded as follows.

[0089] From the original state of the heat-shrinkable polymer from which the warp yarns 10a-10f are formed, the voltage source is controlled to provide an elongation voltage to the conductive yarn 20, which is consequently heated. Once a sufficient temperature is reached, a tensile force F is applied to the fabric 1 in a direction along the warp yarns 10a-10f, and the fabric is pulled to a desired length in a first direction D1.

[0090] The voltage source is then controlled to reduce or turn off the current.

[0091] The dough is then allowed to cool thoroughly.

[0092] Optionally, cooling may be provided by conduction or convection, for example a cooling liquid such as water may be applied to the fabric and / or a cooling gas stream such as air may be applied to the fabric.

[0093] The size of the dough can be reduced as follows:

[0094] From the elongated state of the heat shrinkable polymer from which the warp yarns 10a-10f are formed, the voltage source is controlled to provide a shrink voltage to the conductive yarn 20, which is consequently heated. Once a sufficient temperature is reached, it is ensured that the warp yarn is effectively unloaded so that it can shrink to the desired length. Once the desired shrinkage is achieved, the voltage source is controlled to reduce or turn off the current.

[0095] The dough is then allowed to cool thoroughly.

[0096] Optionally, cooling may be provided by conduction or convection, for example, a cooling liquid may be applied to the fabric and / or a flow of cooling gas, such as air, may be applied to the fabric.

[0097] Optionally, one or more temperature sensors may be disposed on the fabric and operably connected to the controller to provide feedback of the temperature of the fabric 1 so that the current supplied to the conductive yarns may be more precisely controlled.

[0098] FIG. 2 illustrates diagrammatically an embodiment of a size-adjustable fabric 2 identical to that described with reference to FIG. 1, but comprising at least one, and preferably several, additional weft threads 40.

[0099] The additional weft yarn or yarns 40 may optionally be formed of a material that is non-conductive but capable of withstanding temperatures such as those typically produced by the conductive yarns 20 .

[0100] One or more additional weft yarns 40 may completely or partially follow the conductive yarn 20 .

[0101] For example, the additional weft yarns may extend across the same number of warp yarns 10a-10f as the conductive yarns 20 (in the horizontal direction D2 as seen in FIG. 2).

[0102] As an alternative, the additional weft yarn or yarns 40 may extend across fewer warp yarns 10a-10f than the conductive yarns 20.

[0103] As yet another alternative, the additional weft yarn or yarns 40 may extend across more warp yarns 10a-10f than the conductive yarns 20.

[0104] Moreover, the extent of the one or more additional weft yarns 40 in the cross direction D2, as viewed along the warp direction D1, may vary.

[0105] FIG. 3 illustrates generally a size-adjustable fabric 3 in which the extent of conductive yarns 20 varies in direction D2 across warp yarns 10a-10f.

[0106] For example, the conductive yarn 20 may extend across all warp yarns 10a-10f in some rows 20a, 20e.

[0107] In other rows 20b, 20c, 20d, the conductive yarn 20 may extend across a subset of the warp yarns 10b-10e.

[0108] The size adjustable fabric 3 illustrated in FIG. 3 may otherwise be the same as that illustrated and described with reference to FIGS.

[0109] 4a and 4b illustrate generally the operation of a size adjustable fabric as illustrated in any of FIGS. 1-3.

[0110] 4a-4b illustrate diagrammatically how the adjustable fabric 4, 4' is attached to the non-adjustable fabric portions 30a, 30b such that the adjustable fabric 4, 4' forms a connection between the respective non-adjustable fixed size fabric portions 30a, 30b.

[0111] Figures 4a-4b illustrate a size adjustable fabric 4, 4' having eight warp threads 10a-10i. Figure 4a illustrates the fabric 4 in its original state and Figure 4b illustrates the fabric 4' in a stretched state, where the warp threads have been stretched and subsequently cooled as described with reference to Figure 1.

[0112] In Figures 4a-4b, the warp threads 10a-10i extend at an angle of 80-100 degrees, preferably about 90 degrees, relative to the edges of the fabric portions 30a, 30b.

[0113] 4a-4b further illustrate extension-limiting yarns 41, 41' that may be included in the woven material to run parallel to the warp yarns 10a-10i and to provide slack between crossings of the weft yarns 20.

[0114] If the elongation-limiting yarns 41, 41' are formed from a non-heat shrinkable material or from a material that is less susceptible to heat stretching or shrinking than the warp material, then once the fabric 4' is stretched to the extent that the elongation-limiting yarns 41, 41' are stretched, as illustrated in FIG. 4b, the fabric 4' will not stretch any further.

[0115] A plurality of such elongation-limiting yarns 41, 41' may be included in regular ranges between the first set of yarns 10a-10i. Figures 5a-5b illustrate diagrammatically the operation of a size-adjustable fabric 5, 5' essentially as described with reference to Figure 3, i.e. where the extent of the conductive yarn 20 across the warp yarns 10a-10i varies along the warp direction D1.

[0116] In Figures 5a-5b it is illustrated diagrammatically how the adjustable fabric 5, 5' is attached to the non-adjustable fabric portions 35a, 35b such that the adjustable fabric 5, 5' forms a connection between the respective non-adjustable fixed size fabric portions 35a, 35b. In the size adjustable fabric 5, 5' in Figures 5a-5b the lengths of the warp threads 10a-10i are also varied so that the fabric 5, 5' can be given a desired shape, such as a triangle as illustrated.

[0117] An extension-limiting thread, such as that illustrated in Figures 4a-4b, may also be included in the embodiment of Figures 5a-5b.

[0118] In Figures 5a-5b, the edges of the fabric portions 35a-35b are non-parallel and may intersect to form a wedge shape.

[0119] The adjustable fabric 5, 5' is adjusted to an angle a between the first set of threads 10a-10i, 10a'-10i' and the fabric edge with respect to the edge of the fabric portion 35a, 35b. t The angle a between the edge of the fabric and the conductive yarn 20 c may be arranged to be greater than

[0121] FIG. 6 illustrates shoulder seam edge regions 51, side seam edge regions 52, body length seam edge regions 53, and center back seam edge region 54.

[0122] The size-adjustable fabric portions 1, 2, 3 are connected to the back portion 50 in their respective edge regions 51, 52, 53, 54, for example by stitching, and the warp threads are oriented at a larger angle a than the conductive thread 20 portions relative to the respective edges of the back portion 50. t (see Figures 5a-5b)).

[0160] A first patch 103 is provided on the boot shaft for the purpose of providing adjustability of the shaft circumference so that the circumference of the shaft can be adjusted to fit wearers having calf sizes and / or shapes.

[0161] Thus, the boot shaft may comprise a pair of shaft sections 101, 102 separated vertically (when the boot is positioned on a horizontal surface) by a patch of size-adjustable fabric 103. The size-adjustable fabric is thus connected to the shaft sections 101, 102 such that a first set of threads 10a (see Figures 5a-5b) extends between the shaft sections 101, 102, e.g. substantially horizontally.

[0162] The conductive threads 20 (FIGS. 5a-5b) extend substantially perpendicular to the first set of threads 10a, for example substantially horizontally.

[0163] Thus, using the principles described above, by heating the first set of yarns, the distance between shaft portions 101 and 102 can be adjusted to allow the boot shaft to fit perfectly to the user's calf.

[0164] It is also possible to arrange two or more vertically juxtaposed patches 103 between the barrel sections 101 and 102 so that different sections of the barrel can be individually adjustable.

[0165] The patch 103 may be positioned on the rear portion of the barrel, on a side portion of the barrel, or on a front portion of the barrel.

[0166] The patch may be positioned in a concealed manner such that the adjustable fabric is concealed by a piece of material to provide a desired aesthetic appearance and / or prevent the penetration of dirt or moisture.

[0167] FIG. 11 also illustrates a second patch of size-adjustable fabric 105 immediately behind the toe cap 104 as part of the toe cap 106, upper, or tongue.

[0168] This second patch 105 may be connected to the toe box 104 and toe / upper / tongue. The second patch 105 may be oriented such that the first set of threads extends substantially along the width of the boot, thereby making the width and / or height of the boot 100 adjustable.

[0169] It is contemplated to provide footwear having only the first patch 103, only the second patch 105, or both patches 103,105.

[0170] In the case of boots having a shaft, particularly a shaft that extends partially or completely along the calf of the user, such boots may be provided in, by way of non-limiting example, functional boots such as riding boots or motorcycle boots, and in fashion boots, particularly women's boots.

[0171] Short boots, such as ski boots, work boots or hiking boots, may also be provided with one or both of the patches 103, 105.

[0172] Patches 103, 104 may be provided as part of the actual shoe casing and / or as part of a shoe liner (not shown) such as is often found on slalom boots.

[0173] Shoes that do not extend above the heel or ankle may be provided with a second type of patch 105 .

[0174] The portions of the footwear not comprised of patches 103, 105 may be formed of materials such as leather, rubber or reinforced rubber, polymeric or reinforced polymeric materials, or fabrics (woven or non-woven).

[0175] FIG. 12 illustrates protective clothing in the form of a back protector 110 for use when skiing or riding a motorcycle.

[0176] The back protector 110 comprises two or more protective bodies 111, 112, which may be relatively rigid bodies intended to absorb and / or disperse impacts and / or protect against penetration by sharp objects or blades.

[0177] A patch of size adjustable fabric 113 as disclosed above can be placed between the protective bodies 111 and 112 such that the distance between the protective bodies 111 and 112 is adjustable. It is thus possible to provide size adjustability of the protective suit so that its protective capacity can be optimized for each individual user.

[0178] It will be appreciated that because the protective garment may comprise multiple protective bodies 111, 112, patches of size-adjustable fabric 113 may be positioned along any interface region between the protective bodies 111, 112, and each such patch may be individually controllable. It is also possible to provide size-adjustable fabric in some such interface regions while simultaneously providing rigid or elastic fabric in other interface regions.

[0179] The suit may also be provided with one or more patches 115 in the waist or shoulder areas to allow a perfect fit in those areas of the user.

[0180] The protective suit 110 may be a back protector and / or a front protector.

[0181] For example, protective clothing 110 may be provided in the form of shoulder protectors, knee protectors, arm protectors, etc. for use in ice hockey, skiing, motorcycling, and horse riding.

[0182] Other applications may include riot gear used by police or military, or ballistic protective gear.

[0184] Footwear 120 may have a toe portion 121, a heel portion 122, an ankle portion 123, and a tongue portion 124.

[0185] For example, in the toe portion 121, one or more size-adjustable fabric patches or material portions 126 may be provided with a first set of threads 10a extending in a direction Da2 substantially parallel to the length direction of the footwear, such that the length of the footwear is adjustable. In particular, the toe box of the footwear may be produced from a size-adjustable fabric, such that the space made available for the wearer's toes may be fully adjusted.

[0186] It is also possible to place a patch of size-adjustable fabric 129 on the toe cap or upper portion of the footwear, while the toe cap is formed of a conventional fixed size material. The first set of threads 10a may thus extend in a direction substantially parallel to the length of the footwear, and the length of the footwear may be adjusted by adjusting the position of the toe cap relative to the remainder of the footwear.

[0187] It is also possible to provide one or more size-adjustable fabric patches 125 in the heel portion 122 so that the length of the liner 120 can be adjusted. To this end, the first set of threads 10a (see Figures 5a-5b) may extend substantially horizontally.

[0188] It is also possible to provide one or more size-adjustable fabric patches 125 in the ankle portion 123 so that the ankle width of the liner 120 can be adjusted. For this purpose, the first set of threads 10a (see Figures 5a-5b) may extend substantially horizontally.

[0189] In one embodiment, the size adjustable fabric patch extends along the entire back side of the footwear, such as from the insole to the opening of the footwear, and the first set of threads 10a extend substantially horizontally.

[0190] Such footwear can be adjusted to fit a user by supplying an electric current through the second set of threads 10b to heat the size-adjustable fabric and fit the footwear to the user, whereby the first set of threads 10a is allowed to cool while the footwear is being worn by the user.

[0191] The supply of power may occur before the footwear is fitted by the user or while the footwear is being worn by the user.
