Description

Title of the invention: Method for manufacturing a cap and corresponding cap technical field

[0001] The present invention relates to the field of clothing accessories, and more particularly to that of caps. The invention relates more specifically to the field of thermoformed caps. Previous technique

[0002] Caps are typically manufactured from a plurality of elements, generally assembled by hand and requiring several steps. Thus, the crown, or cap, intended to be positioned on the user's head, comprises, in a known manner, several adjacent textile panels, identical or different, generally triangular in shape, assembled together to obtain a general hemispherical shape. In particular, the panel positioned on the front side of the cap may differ, in shape and / or material, from the other panels of the crown.

[0003] A visor is then added to the crown, on one side of it, as well as an inner band mounted on the inner peripheral edge of the crown.

[0004] In addition, other accessories can be added to the cap, such as: a top button positioned at the junction of the tops of the different textile panels forming the crown, one or more eyelets allowing ventilation through the crown, and / or a means of adjusting the peripheral length of the crown, generally mounted on the crown opposite the visor.

[0005] However, such a cap design remains relatively complex and is difficult to automate industrially, leading to predominantly manual manufacturing. This therefore implies longer manufacturing times and higher costs.

[0006] It is also known to manufacture a cap by thermoforming a stretchable textile panel to form the crown. Such a design is notably described in document WO2018 / 010124. Once the crown is thermoformed, the various accessories are added, including a triangular front panel mounted inside the crown, and a visor mounted on the crown and said triangular front panel.

[0007] However, such a cap still requires several manufacturing steps, including manual ones, and does not provide substantial gains, in terms of time or manufacturing costs, compared to caps manufactured in a traditional way.

[0008] Furthermore, such caps were not designed within an ecological framework of industrial waste reduction and / or reuse of industrial waste or recycled materials, in order to limit their environmental impact. More specifically, prior art caps are designed and developed using the same traditional process implemented for several decades, and not to adapt to current constraints of recyclability or reuse of recyclable materials. Description of the invention

[0009] The present invention aims to solve the various technical problems stated above. In particular, the present invention aims to provide a cap designed to reduce industrial waste and to utilize recycled materials. More specifically, the present invention aims to provide a cap with a simplified and less expensive design, taking into account environmental constraints in order to limit its impact.

[0010] Thus, according to one aspect, a method for manufacturing a cap comprising: - a crown configured to be positioned on the user's head, and - a visor positioned and extending from one side of the crown.

[0011] In particular, - a multi-layered textile panel is produced comprising: a non-woven veil or felt made from a mixture of recycled, natural and / or synthetic fibers and fusible fibers, and at least one woven or knitted layer, for example a knit, positioned on one face of said non-woven veil, preferably two woven or knitted layers positioned on two opposite faces of the non-woven veil, then - a thermoforming step is carried out on said multilayer textile panel so as to, at least in part and preferably entirely, form said crown and said visor in a unitary manner, the thermoforming step being configured to at least partially bond the hot melt fibers to recycled fibers by melting the hot melt fibers, and to bond the woven or knitted layer(s) to the face(s) of the non-woven veil.

[0012] In other words, the crown and the visor of the cap according to the present invention are formed, at least in part and preferably entirely, from a single panel which is thermoformed to have, on one side, the shape of a crown, and on the other side, the shape of a visor. The multilayer textile panel is therefore a single, or unitary, multilayer textile panel that forms, at least in part and preferably entirely, both the crown and the visor of the cap. The multilayer textile panel of the cap extends continuously between the crown and the visor. The crown and the visor of the cap are therefore already connected to each other without needing to be assembled together.

[0013] Thus, thanks to the process according to the invention, it becomes possible to produce caps similar in shape to those of the prior art, simply and inexpensively. More specifically, the simultaneous shaping of the crown and the visor from a single multilayer textile panel eliminates the need for the traditional steps of assembling different textile panels to obtain the three-dimensional shape of the cap. In the context of the present invention, a thermoforming step allows the hemispherical crown and the substantially flat visor to be formed simultaneously, and this shape to be fixed over time, notably through the use of heat-fusible fibers.

[0014] Furthermore, in addition to simplifying the manufacturing process, the present invention also allows for the reuse of recycled materials, thanks to the non-woven fabric of the multilayer textile panel. The multilayer textile fabric advantageously incorporates, in addition to the heat-fusible fibers that allow for shaping and maintaining the cap's structure, recycled fibers within the material itself. The cap according to the present invention thus also allows for the valorization of unused materials from industrial processes or materials from recycling or recovery processes. In addition to limiting the environmental impact, such use of materials also reduces the manufacturing costs of the cap.

[0015] For example, the non-woven fabric can have, before thermoforming, a thickness of between 10mm and 30mm, preferably between 12mm and 20mm.

[0016] To provide improved mechanical resistance, particularly to abrasion, the non-woven fabric can be covered, on one or both sides, with a woven or knitted layer, for example, a knit fabric. Such a woven or knitted layer thus limits premature wear of the non-woven fabric, even when thermoformed, by improving the mechanical resistance of the surface of the multilayer textile panel. Furthermore, the addition of such a woven or knitted layer also allows for a choice of aesthetic and / or tactile characteristics for the multilayer textile panel. It is then possible to choose more freely the recycled fibers used to form the non-woven fabric, since the latter can potentially be concealed by the woven or knitted surface layer(s).In particular, the colours and / or the mix of recycled fibres will not necessarily be visible to the user, making it even easier to choose which fibres can be used in the non-woven fabric of this cap.

[0017] Alternatively, the woven or knitted layer(s) may be chosen to be partly transparent in order to leave, at least partially, the non-woven veil visible and in particular its composition based on recycled fibers.

[0018] Preferably, the production of the multilayer textile panel includes in particular a step of producing said non-woven veil during which the fibers are dispersed in an airflow before being deposited on a support.

[0019] The non-woven fabric is manufactured in such a way as to allow, on the one hand, for the homogenization of the different constituent fibers, in particular homogenization between the recycled fibers and the heat-fusible fibers, so as to obtain a homogeneous thermoformed multilayer textile panel. Such a manufacturing process for the non-woven fabric also makes it possible to have a multilayer textile panel, before thermoforming, with a thickness, or volume, that is relatively greater than the thickness, or volume, of the same multilayer textile panel after thermoforming. In particular, such a variation in thickness, or volume, can be advantageously used during the three-dimensional shaping of said multilayer textile panel.

[0020] Preferably, the step of producing said non-woven veil also includes, after the dispersion and deposition of the fibers, a fixing of the fibers together, for example thermal, such as calendering, or mechanical, such as needle punching.

[0021] In order to improve the durability of the non-woven fabric and also facilitate subsequent steps in the cap manufacturing process, the fibers of the non-woven fabric can be bonded together. This also allows for better adhesion of the woven or knitted layer(s) to the surface(s) of the non-woven fabric after the thermoforming step.

[0022] Preferably, during the thermoforming step, an embossing step is also carried out on the multilayer textile panel, so as to create a pattern on the crown and / or the visor.

[0023] The thermoforming step is preferably carried out using a mold inside which the multilayer textile panel is positioned and deformed with the application of heat. It is thus possible to provide a mold with surface reliefs so as to obtain, in addition to the thermoforming of the multilayer textile panel, an embossing intended to reproduce a pattern on the surface of the cap. For example, the pattern can suggest the presence of seams on the visor or crown, for example by creating lines corresponding to the assembly seams of traditional caps, or imitate the presence of a button on the upper part of the crown. Such an embossing step, simultaneous with the thermoforming step, makes it possible to increase the detail achieved during the three-dimensional shaping of the cap, without adding an extra step to the manufacturing process.

[0024] Preferably, the thermoforming step includes a preliminary step of preheating the multilayer textile panel.

[0025] In order to improve and reduce the duration of the thermoforming step, a preliminary preheating step can be included, for example using infrared. This facilitates, in particular, the deformation of the multilayer textile panel during the closing of the thermoforming mold.

[0026] Preferably, the thermoforming step includes a preliminary step of adding a means of stiffening the visor, such as thermosetting powder, for example thermosetting EVA (ethylene-vinyl acetate) or such as an additional textile panel attached to the multilayer textile panel.

[0027] In order to obtain different stiffnesses between the crown and the visor, it is possible to add a stiffening means to certain specific areas of the cap, particularly at the visor. The stiffening means can, for example, be in the form of a thermosetting powder or an additional textile panel, and be added before the thermoforming step, to the areas to be stiffened, for example, on the visor. It then becomes easy to obtain a cap according to the present invention, with different stiffnesses, while retaining the advantages detailed above.

[0028] Preferably, the thermoforming step includes a subsequent step of cutting excess material from the thermoformed multilayer textile panel.

[0029] To avoid any fine-tuning of a pre-cut multi-layer textile panel in the thermoforming mold, it is preferable to use a multi-layer textile panel larger than the thermoforming mold and then trim the excess after the cap has been thermoformed. To facilitate such trimming, the thermoforming mold may include an integrated cutting means configured to perform a cut along the peripheral contour of the mold cavity during or immediately after the thermoforming step. The peripheral contour of the cavity of one of the cap mold parts can thus form a counter-blade for the cutting means.Such an integrated cutting system allows for a cut that perfectly matches the shape of the mold cavity, and therefore the desired final shape of the cap. This simplifies and accelerates the cap manufacturing process and eliminates the need for a subsequent manual cutting step. Furthermore, this integrated cutting system allows the cutting step to be performed immediately after the thermoforming step, either simultaneously or just after, preferably in a single vertical movement of the mold. This eliminates the need for an additional cutting machine and the associated handling steps.

[0030] According to another aspect, a cap obtained by the process described above is also proposed.

[0031] A cap is thus proposed, in particular one that can be obtained by the process described above, comprising: - a crown configured to be positioned on the user's head, and - a visor positioned and extending from one side of the crown.

[0032] The visor and the crown are, at least in part and preferably entirely, formed as a single unit from a multilayer textile panel, said multilayer textile panel comprising: - a non-woven veil or felt comprising a mixture of recycled, natural and / or synthetic fibers, and fibers at least partially melted bonded to recycled fibers, and - at least one woven or knitted layer, bonded on one face of said non-woven veil, preferably two woven or knitted layers bonded on two opposite faces of the non-woven veil.

[0033] Thus, as previously stated, the crown and the visor are formed, at least in part, from a single multi-layered textile panel extending continuously between the crown and the visor. The resulting cap, in addition to being easier to manufacture than traditional caps and incorporating recycled materials, allows for the visor and crown to be bonded together.

[0034] Preferably, the non-woven veil is obtained by thermoforming a flat layer of recycled fibers and hot-melt fibers formed by an aerodynamic process.

[0035] The aerodynamic process makes it possible to obtain a homogeneous mixture of recycled fibers and hot-melt fibers prior to the thermoforming step.

[0036] Preferably, the fibers of the non-woven veil are also entangled with each other.

[0037] Preferably, the non-woven veil comprises between 5% and 40% by mass of at least partially melted fibers, preferably between 10% and 20% by mass.

[0038] The proportion of fibers at least partially fused in the non-woven fabric allows the mechanical and strength properties of the multi-layered textile panel forming the cap to be modified.

[0039] Preferably, the non-woven veil has a surface mass of between 150 and 400g / m2, preferably between 250 and 300g / m2, and / or said at least one woven or knitted layer has a surface mass of between 50 and 200g / m2, preferably between 100 and 150g / m2.

[0040] Preferably, the visor also includes an added stiffening means, for example a thermosetting element or an additional textile panel, added to the multilayer textile panel.

[0041] Preferably, the cap includes patterns, in particular imitating stitching on the visor, obtained by embossing the multilayer textile panel. Brief description of the drawings

[0042] [Fig-1] Fig. 1 represents, schematically, a cap according to the present invention, side view;

[0043] [Fig.2] Fig.2 schematically represents the cap illustrated in the [Fig. 1], top view; and

[0044] [Fig.3] Fig.3 schematically represents the cap illustrated in the [Fig.l], with an enlarged edge to detail its structure. Description of the implementation methods

[0045] Figures 1 to 3 schematically illustrate an example of a cap 1 according to the present invention. The cap 1 has a generally classic shape with a crown 2 in the form of a hemisphere to accommodate the user's head, and a visor 4 that is substantially flat and extends from an edge of the crown 2.

[0046] In particular, and as described below with the manufacturing process, the crown 2 and the visor 4 are formed, for example, integrally, as a single unit, that is to say, from one and the same piece, in this case a multi-layered textile panel 6 illustrated in [Fig. 3]. In other words, the crown 2 and the visor 4 are manufactured as a continuous piece, unlike prior art caps for which the visor is an added piece on the crown.

[0047] The cap 1 according to the present invention is therefore mainly a cap formed from a single piece, possibly with added accessories such as an adjustment means, which facilitates its manufacture by reducing the steps, and therefore the time and the cost.

[0048] Furthermore, the multilayer textile panel 6, which forms both the crown 2 and the visor 4, also allows for the utilization of underutilized materials such as unused fibers from industrial processes or recycling / recovery processes. Such fibers are thus blended with heat-fusible fibers to form a non-woven fabric 8 intended to be thermoformed to obtain the crown 2 and the visor 4 of the cap 1.

[0049] The method for obtaining the cap 1 according to the present invention is described more specifically below.

[0050] Initially, the non-woven fabric 8 is manufactured. This fabric comprises, on the one hand, recycled fibers, to valorize underutilized waste, and fibers hot melts intended to bind the fibers of the non-woven web 8 after thermoforming, thanks to the at least partial melting of said hot melt fibers which will allow a mechanical bond between at least part of the fibers (recycled and hot melt) of the thermoformed non-woven web 8.

[0051] To obtain a uniform mixture of recycled and hot-melt fibers, these are blended together using an aerodynamic process: the fibers are dispersed in an airflow before being deposited onto a substrate. This results in a homogeneous deposit of recycled and hot-melt fibers. Subsequently, the blended fibers can be at least partially entangled together, for example by calendering or needle punching, to obtain a non-woven web 8 with sufficient mechanical strength to allow, in particular, handling for subsequent process steps.

[0052] For example, the non-woven veil 8 may comprise between 5% and 40% by mass of heat-fusible fibers, preferably between 10% and 20% by mass.

[0053] Furthermore, the non-woven veil 8 can have a surface mass of between 150 and 400g / m2, preferably between 250 and 300g / m2.

[0054] In order to improve the surface mechanical resistance, in particular wear resistance, and to obtain the desired appearance for the cap, the non-woven fabric 8 is covered, on one or both sides, with a woven or knitted layer. Thus, the non-woven fabric 8 can be covered on its upper surface by a woven or knitted layer 10, and / or covered on its lower surface by a woven or knitted layer 12. The assembly formed by the non-woven fabric 8 and the woven or knitted layer(s) 10, 12 constitutes the multi-layered textile panel 6.

[0055] In particular, the heat-fusible fibers of the non-woven veil 8 also allow a chemical bond with the woven or knitted layer(s) 10, 12.

[0056] Preferably, the woven or knitted layer(s) 10, 12 are knitted. Such knitted layers 10, 12 exhibit both sufficient elasticity to allow their deformation during the thermoforming process, and on the other hand, a higher mechanical resistance, particularly wear resistance, than that of the non-woven fabric 8.

[0057] The woven or knitted layer(s) 10, 12 may have a surface mass between 50 and 200g / m2, preferably between 100 and 150g / m2.

[0058] The multi-layered textile panel 6 thus obtained is still flat, but ready to be thermoformed into the desired shape of the cap 1.

[0059] Thus, the multilayer textile panel 6, whose surface area is much larger than that of the cap 1, is positioned inside a thermoforming mold. For example, the mold may comprise two parts, and the two parts of the thermoforming mold are placed opposite each other, on either side of the multilayer textile panel 6. The thermoforming mold has, at the interface between the two parts of the mold, a cavity having the general shape desired for the cap 1. The multi-layered textile panel 6 protrudes from the thermoforming mold on the entire periphery of the mold cavity, so that no part of the mold remains empty during thermoforming.

[0060] During the thermoforming step, the multilayer textile panel 6 is therefore deformed by the closing of the mold, to conform to the shape of the cavity imposed by the mold, and heated so as to melt, at least partially, the thermofusible fibers of the non-woven web 8. By melting, said thermofusible fibers will then bond with the recycled fibers near the non-woven web 8, as well as with the woven or knitted layer(s) 10, 12.

[0061] At the end of the thermoforming step, the multilayer textile panel 6 thus formed is cooled so that the molten hot melt material solidifies in particular on the recycled fibers and / or the woven or knitted layer(s) 10, 12, thus leading to the formation of a cap whose elements of the multilayer textile panel 6 are linked, or joined, together by the at least partially melted fibers.

[0062] In particular, the melting of the hot-melt fibers makes it possible to link the fibers or elements of the multilayer textile panel 6 together, but also to fix the shape of said multilayer textile panel 6 during the thermoforming process, that is to say, to fix the shape of the multilayer textile panel 6 to the shape of the cap 1. Thus, in a single thermoforming step of a given panel, a cap comprising a crown and a visor is obtained.

[0063] For example, the non-woven veil may comprise between 5% and 40% by mass of at least partially melted fibers, preferably between 10% and 20% by mass.

[0064] To facilitate the thermoforming step, this step may include a preheating step for the multilayer textile panel 6. Such preheating may, for example, be carried out by exposing the multilayer textile panel to infrared radiation. This preheating makes the multilayer textile panel more pliable before it is placed in the thermoforming mold, and thus facilitates its deformation within the thermoforming mold.

[0065] Furthermore, it is also possible to provide, before positioning the multilayer textile panel 6 in the thermoforming mold, for the application or addition of a stiffening means 14 to one or more parts of the cap 1, in order to obtain a cap 1 with different stiffnesses. For example, a powder, preferably thermosetting such as thermosetting EVA, or an additional textile panel can be deposited on the part of the multilayer textile panel 6 intended to form the visor 4, so as to obtain, after thermoforming, a cap 1 with a flexible crown 2 and a more rigid visor 4.

[0066] Similarly, during the thermoforming step, it is also possible to incorporate reliefs into the thermoforming mold to create patterns 16 on the cap 1 by embossing. This makes it easy to suggest stitching lines, or other patterns 16, for example on the visor 4, by providing a thermoforming mold with the appropriate corresponding reliefs to create such patterns 16 by embossing.

[0067] Finally, and as previously indicated, the multilayer textile panel 6 has a larger surface area than the thermoforming mold, so as not to require a preliminary step of finely positioning said panel in the mold. Alternatively, a multi-mold can be used, featuring several identical cap shapes arranged side by side, and a multilayer textile panel 6 with a larger surface area than said multi-mold can be positioned on it, thus allowing the manufacture of several caps in a single thermoforming step.

[0068] However, once formed, the cap(s) must then be separated from the rest of the multilayer textile panel 6: such separation is carried out by cutting, during or after the thermoforming step and, preferably, using a cutting means integrated into the thermoforming mold. In other words, one part of the thermoforming mold may include a retractable cutting means extending along the peripheral edge of the thermoforming cavity and cooperating with a peripheral edge of the cavity of the other part of the mold acting as a counter-blade. The cutting means is configured to deploy during or after the thermoforming step, in order to cut the portion of the multilayer textile panel 6 protruding from the cavity of said mold.

[0069] An individual cap is then obtained directly from the thermoforming mold.

[0070] An additional cutout 18 can be provided for mounting a means (not shown) for adjusting the peripheral length of the crown. Such conventional adjustment means already exist in traditional caps, allowing the user to adjust the cap size to their head circumference.

[0071] Finally, further customization steps can then be planned, such as the addition of patches or accessories such as a top button on the top of the cap.

[0072] Thus, thanks to the process according to the invention, it becomes easier and less expensive to manufacture a traditionally shaped cap. The various characteristics of the The cap, and in particular the construction of its multi-layered textile panel, allows for the reuse of recycled or otherwise unused materials from industrial processes, while maintaining the mechanical properties required for the cap's intended use, notably its wear resistance and visor rigidity. Finally, such a cap remains compatible with customization and adjustment accessories, appealing to the target audience while ensuring comfortable wear.
