Abstract

The present disclosure relates to a filler (10, 10a) having a thermal insulation function. The filler comprises a sheet-like body having a first surface (15) and a second surface (16) on opposite sides. The sheet-like body (12) has a plurality of partially cut portions. At least one of the partially cut portions protrudes from at least one of the first surface (15) and the second surface (16) of the sheet-like body (12).

Description

[0001] This disclosure generally relates to padding materials whose primary and preferred function is to provide thermal insulation, and preferably also to ensure comfort. This disclosure also relates to clothing or wearable articles in general that include said padding materials.

[0002] As is well known, soft padding is required to manufacture clothing. The main function of this padding is to insulate the user's body from the outside, thereby ensuring that the user obtains the greatest possible thermal comfort.

[0003] As is also well known, since air is the best insulation material, it is important to ensure that the filling material is as breathable as possible.

[0004] To achieve this, people have been constantly exploring increasingly advanced materials that can create as many hollow areas as possible for air circulation within the same thickness, thereby improving thermal insulation.

[0005] This disclosure is based on the authors' understanding that such exploration has increasingly focused on finding higher quality, more expensive, and more popular materials. Therefore, these materials may impact production costs, and thus necessitate the development of fillers in an alternative manner that reduces expenditures on said materials.

[0006] This disclosure is based on the authors’ understanding that it is necessary to investigate possible structures of fillers that increase airflow, rather than focusing on the materials described.

[0007] One technical problem of this disclosure is to provide a filler having a structure that enables increased internal airflow when using the same material; and / or to provide a filler that can provide other advantages.

[0008] This is achieved through the filling and method according to the respective independent claims. The secondary features constituting the subject matter of this disclosure are described and defined in the respective dependent claims.

[0009] The heat-insulating filler according to this disclosure includes a sheet-like body having an internally hollow structure or a structure defined by a solid and porous structure, and a first surface and a second surface, the two surfaces being located on opposite sides. Essentially, the filler according to this disclosure comprises a sheet-like body that is inherently three-dimensional in structure. In other words, the sheet-like body is not merely a simple layer, but rather consists of layers of suitable thickness. Therefore, the filler should be understood as forming a structure of a certain thickness (e.g., between two layers of clothing) to provide thermal protection.

[0010] The sheet-like body has a plurality of partially cut portions, wherein the portions are partially cut relative to the remainder of the sheet-like body, i.e., they are in a cut state, and at least one of the partially cut portions is raised or displaced relative to the remainder of the sheet-like body, and protrudes relative to either the first surface or the second surface of the sheet-like body. In other words, each partially cut portion has a region separate from the remainder of the sheet-like body and a region connected to the remainder of the sheet-like body, wherein the connecting region acts as a bend or fold.

[0011] Each part that is cut or separated is stably fixed in this protruding or cut state. In other words, once each part is cut or separated, it cannot be moved but remains in that raised or protruding position.

[0012] This protruding state can be achieved by gluing, sewing, needle punching, or direct fixation to the bottom and top fabrics, wherein the sheet is clamped in by operations such as gluing, sewing, ultrasonic welding, or high-frequency welding. In other words, at least one of the cut locations of said portions, or at least one separated portion of said portions, is stably fixed in the protruding position by gluing, sewing, or needle punching.

[0013] Essentially, a filler is provided in which the layer defined by the sheet-like body can be enlarged by partially lifting a portion of the sheet-like body, thus leaving additional hollow regions within the sheet-like body in which the portion of the sheet-like body has been removed. These additional hollow regions should be understood to be in addition to the “hollow” regions or pores of an internally hollow structure or a structure defined by dense solids and pores.

[0014] The portion may be pre-cut or separated at the beginning of sheet production. Therefore, the term "partially cut portion" should be understood as meaning the portion that has been separated from the rest of the sheet, a result of the cutting process and the production process. Thus, it must also be understood as simply the portion that has been separated.

[0015] Preferably, the portions of the plurality of partially cut sections protrude relative to one of the first surface and / or the second surface.

[0016] These sections are not completely cut off, but rather raised, allowing the total volume of the sheet to increase relative to the volume defined by the sheet. This results in a greater overall thickness of the filler for the same amount of material used, and ensures greater airflow and space within the sheet.

[0017] Air can circulate in the intermediate zone between the partially cut section and the adjacent section.

[0018] Furthermore, the channels for water vapor generated by the human body are confined within various intermediate zones. In other words, within the filling material, between the cut or separated sections, there exists a series of through channels for water vapor generated by the human body. In this way, one of the limitations of ordinary filling materials, namely poor air permeability, is overcome.

[0019] Therefore, this disclosure provides the significant advantage of increasing the presence of air within the filler for the same amount of the filler material. More precisely, it increases the presence of air known as optimal insulation material, for example, between fabric layers or between two layers in which sheet-like materials are typically sandwiched.

[0020] Volume can be increased by arranging the partially cut sections so that they protrude from both surfaces. On the other hand, if the thickness is kept small, it is sufficient for the cut sections to protrude from only one surface. Therefore, to control the final insulation performance, the partially cut sections can be arranged so that they protrude from the same side or opposite sides of the sheet as needed.

[0021] The filler according to this disclosure allows for the possibility of adjusting the thickness as needed.

[0022] The material used to make the sheet is a filler or stuffing material, that is, a material that is soft enough in the case of clothing products and allows partially cut parts to remain separate or folded so as to lift them without damaging them, such as non-woven fabrics, needle-punched materials, felt, foam rubber, stuffing, high-density interwoven fibers, sheets made of soft plastic materials, expanded soft structures, or similar internal hollow structures.

[0023] As mentioned above, this material is one that allows for the imparting of a three-dimensional structure to sheet-like structures.

[0024] It should be noted that, in the context of this disclosure, the term "filling" can be understood to mean a soft structure used in clothing, and generally in applications associated with the textile industry.

[0025] Another advantage is that the thickness of the filler material can be increased without increasing the weight of the filler itself.

[0026] This results in a filling material that can ensure greater thermal insulation without increasing the weight of clothing or other wearable products that include the filling material.

[0027] Another advantage is the fact that a filler can be provided that requires less material waste to achieve the same insulation effect.

[0028] Preferably, to achieve the greatest possible airflow, the portion cut in each section is obtained by through-cutting, or, as mentioned, by separation during production, for example, creating a through-hole between the first and second surfaces, thereby creating a hole in the sheet body left by the cut portion relative to the remainder of the sheet body. Thus, the sheet body has a plurality of through cavities. Preferably, the cutting or separation generally follows a continuous line much larger than the connection area between the partially cut portion and the remainder of the sheet body, thereby forming a through cavity. In other words, the portion cut in each section separates along most of its respective edge and joins to the remainder of the sheet body along a smaller or minimum portion, solely to ensure a connection.

[0029] Preferably, each through cavity is fully visible. In other words, the cut or separated portions of each section do not overlap on the corresponding through cavity, making them fully visible. This has the advantage of facilitating airflow.

[0030] More preferably, the portion cut from each section is substantially displaced relative to the corresponding through cavity.

[0031] According to the first aspect, to allow for prioritized control of insulation capacity, all partially cut sections are identical. According to the second aspect, the partially cut sections differ in form according to the body regions they are located in, so as to allow greater breathability in areas where water vapor is generated. Again, according to the first aspect, the partially cut sections are arranged at regular intervals along the sheet. In this way, the form of the sheet to be obtained can be pre-organized according to the function of the final filler, for example, by cutting by size or specification. According to the second aspect, the partially cut sections differ in location and density according to the body regions they are located in, so as to allow greater breathability in areas where water vapor is generated.

[0032] Preferably, the filler includes at least one first lining layer attached to a first surface of the sheet and a second lining layer attached to a second surface of the sheet to define a sandwich or bag-like structure. In other words, the filler has a sandwich structure in which the sheet is lined by the first lining layer attached to the first surface and the second lining layer attached to the second surface. The first and second lining layers are arranged opposite to each other relative to the sheet.

[0033] Preferably, at least one of the first lining layer and the second lining layer is bonded to at least one portion, preferably all portions, of the plurality of partially cut or partially separated portions. Bonding to individual components of the sheet can be performed by operations such as stitching, gluing, or ultrasonic welding or high-frequency welding.

[0034] The first and second lining layers define a protective layer suitable for protecting the inner sheet-like structure. In other words, the first and second lining layers are configured to protect the sheet-like structure, and thus also protect the plurality of partially cut or partially separated portions.

[0035] These lining layers can be used to keep partially cut sections permanently or stably raised.

[0036] In this way, the filler can be automated by gluing or by directly attaching the sheet to the respective first liner and the respective second liner.

[0037] In this way, there are the following advantages: the filler can be easily handled and managed in roll form because the partially cut or partially separated parts are protected and do not tangle.

[0038] According to a preferred embodiment, the first lining layer and the second lining layer are each defined by a fabric with a weight of about 10 g / m² to about 300 g / m².

[0039] The first and second lining layers can be thin coverings or fabrics forming the lining and fabrics forming the outer layer of the garment.

[0040] In the case of a thin cover, the filler may be included between two additional layers arranged opposite each other and defining an inner cavity. In this state, the additional layers may contact the first and second lining layers of the sheet, respectively. Alternatively, the lining layers may be glued or otherwise directly attached to the outer layer.

[0041] In the case of the fabric forming the outer layer, the first and second lining layers have a sufficiently high basis weight that the outer layer is not required.

[0042] Therefore, the two lining layers can be layers of clothing or other wearable articles, such as a layer defining the inner lining of a garment and a layer defining the outer or outer layer of the same garment.

[0043] It should be understood that other layers may be disposed between the first layer and the second layer, and filler may be disposed between them.

[0044] Therefore, it can be understood that the filling material according to this disclosure is suitable for integration with clothing in a variety of ways.

[0045] This disclosure also relates to a method for manufacturing a filler with insulating properties, said method comprising the following steps:

[0046] - Provide a sheet having an internally hollow structure or a structure defined by a solid and pores, and a first surface and a second surface, the first surface and the second surface being two surfaces located on opposite sides;

[0047] - Cut the sheet to define a partially cut portion that is connected to the rest of the sheet via a connecting region, or produce the sheet to have a partially separated portion that is connected to the rest of the sheet via a connecting region;

[0048] - Displace or lift at least one of the cut portion or the separated portion of the portion so that it protrudes from at least one of the first surface and the second surface of the sheet body, and fix it stably in the protruding state.

[0049] Furthermore, the method may also include the steps of providing a first lining layer attached to a first surface of the sheet and a second lining layer attached to a second surface of the sheet. According to a first aspect, the first and second lining layers may be arranged to be attached to the first and second surfaces of the sheet, respectively, by gluing, sewing, ultrasonic welding, high-frequency welding, or other similar or equivalent processes. Advantageously, the first and second lining layers may be formed directly from the fabric forming the garment lining and the fabric forming the garment outer layer.

[0050] The filler obtained by the method can be a filler with the characteristics defined above.

[0051] In particular, preferably, the cut or separated portions of each part are glued, sewn, or needled to hold it stably in its protruding position. As a result, for example, the filler can be manufactured by fixing the sheet to the lining layer in a manner that keeps it in a protruding state.

[0052] Further advantages, features, and uses that constitute the subject matter of this disclosure will become clear from the following detailed description of embodiments thereof, which are provided by way of non-limiting examples.

[0053] In any event it is clear that each embodiment constituting the subject matter of this disclosure may have one or more of the advantages listed above; in no event is it required that each embodiment should have all of the advantages listed simultaneously.

[0054] Please refer to the diagram in the attached figure, where:

[0055] - Figure 1 A partial cross-sectional view or sectional view of the garment is shown, in which the filling material according to one embodiment of the present disclosure can be seen;

[0060] - Figure 6 It shows according to Figure 4 Axonometric view of the filling material;

[0061] - Figure 7 A schematic top view of the filler according to another embodiment of this disclosure is shown;

[0062] - Figure 8 It shows Figure 7 The cross section along line VIII-VIII.

[0063] Referring to the accompanying drawings, these figures illustrate a filling 10 that has a heat-insulating function and is preferably used in clothing 100. According to... Figures 4 to 6 The filler 10a is only similar to it in its more schematic and geometric shape. Figures 1 to 3 Although the fillings may differ, it should be understood that they contain the same characteristics and therefore retain the same reference numerals.

[0064] Preferably, the fillings 10, 10a are made of a soft and flexible material and are suitable for being sandwiched between layers 101 and 102 of the garment 100.

[0065] The fillers 10, 10a include sheet-like bodies 12, i.e., bodies having a substantially cushion-like form. In other words, a sheet-like body is a body with a three-dimensional structure having both empty and dense regions. The sheet-like body 12 is made of soft and flexible materials such as nonwoven fabrics, needle-punched materials, felt, foam rubber, wadding, high-density interwoven fibers, sheets made of soft plastic materials, expanded soft structures, or similar internally hollow structures. Generally, as described above, the fillers 10, 10a include sheet-like bodies 12 having an internally hollow structure or a structure defined by dense regions and pores.

[0066] The filling material 10, 10a includes a first surface 15 and a second surface 16, that is, two surfaces located on opposite sides, for example, the first surface 15 points towards the user's body (after the filling material is inserted into the clothing), and the second surface 16 points outward.

[0067] In the context of this disclosure, the first surface 15 and the second surface 16 should be understood as opposite sides of the sheet 12.

[0068] The sheet 12 has a plurality of cuts 18 that define a corresponding number of partially cut portions 20. Essentially, the partially cut portions 20 are portions that are partially separated from the rest of the sheet 12 and partially connected to the rest of the sheet 12 through connecting regions 22 that act as bending regions.

[0069] The cut portions can be obtained either through actual cutting or during manufacturing, for example, by mechanical action when the sheet is formed. According to one aspect of this disclosure, the cut portion 20 of each portion protrudes from at least one of the first surface 15 and the second surface 16 of the sheet 12. Essentially, the cut portion 20 of each portion of the sheet 12 is slightly raised relative to the rest of the sheet 12 to protrude from its respective protruding surface. In this way, for the same amount of material, the same sheet 12 occupies a greater thickness. This allows for an increase in the empty area inside the filler 10 without increasing the weight of the filler material itself.

[0070] The partially cut portion 20 is designed to remain stably fixed in this protruding or raised position. Preferably, each partially cut portion 20 is held in place by gluing, stitching, or needle punching.

[0071] Therefore, a larger hollow or empty area is obtained corresponding to the hollow area between the partially cut and raised portion and the adjacent raised portion cut portion.

[0072] Preferably, each cut 18 is a through cut between the first surface 15 and the second surface 16, thereby defining a through hole or through cavity 25 in the sheet 12.

[0073] It should be noted that, preferably, the through-hole or through-cavity 25 is fully visible. This means that the partially cut portion 20 does not overlap the through-cavity 25, thereby facilitating better airflow. More preferably, as... Figure 2 As shown, the portion 20 cut from each section is substantially displaced relative to the corresponding through cavity 25.

[0074] Therefore, not only is an increased hollow area obtained between the portion 20 cut from the raised portion and the adjacent portion cut from the raised portion, but also an increased hollow area is obtained by the through cavity 25 left by the portion cut from the same portion formed in the thickness of the sheet.

[0075] However, it is also possible that the incision could be another incomplete cut. In this case, the partially cut portion corresponds only to the portion of the sheet-like body that has been raised.

[0076] More specifically, this solution can be effective for "more rigid" fillers.

[0077] Even more preferably, in order to lift the largest possible portion of the partially cut, the cut, or more generally the separation, extends along a continuous line that is larger and longer than the continuous line of the connecting region. In this way, the connecting region (which, as previously described, acts as a bending region) allows the partially cut portion to be lifted as much as possible.

[0078] Even more preferably, as can be seen from the figure, the partially cut portion 20 protrudes from the same portion of the sheet 12.

[0079] Even more precisely, the cut portions 20 are aligned with each other within the sheet-like body. For example, the partially cut portions 20 are arranged at regular intervals along the sheet-like body to form a uniform configuration. This uniform structure allows the insulation properties of the sheet to be predetermined, and allows the filling material to be used as a "standard" filling material in clothing or similar accessories or wearable articles.

[0080] This result can be further obtained if the parts that are partially cut are identical to each other.

[0081] According to the preferred implementation scheme, in Figure 7 and Figure 8 As shown, the filler includes at least a first lining layer 30 attached to a first surface 15 of the sheet 12 and a second lining layer 31 attached to a second surface 16 of the sheet 12, in order to define a sandwich or bag-like structure.

[0082] In other words, the filler 10 has a sandwich structure, wherein the sheet 12 is lined by a first lining layer 30 and a second lining layer 31 arranged opposite to each other. The first lining layer is arranged to be attached to a first surface 15 of the sheet 12, while the second lining layer 31 is arranged to be attached to a second surface 16 of the sheet 12.

[0083] Preferably, at least one of the first lining layer 30 and the second lining layer 31 is combined with at least one portion of the aforementioned plurality of partially cut or partially separated portions 20, preferably all portions.

[0084] For example, the first lining layer 30 or the second lining layer 31 is combined with at least one portion of the aforementioned plurality of partially cut portions 20, preferably all portions.

[0085] The first liner layer 30 and the second liner layer 31 define a protective layer suitable for protecting the inner sheet 12. In other words, the first liner layer 30 and the second liner layer 31 are configured to protect the sheet 12, and thus also protect the plurality of partially cut portions 20.

[0086] Therefore, the filler 10 offers the following advantages: it can be easily handled and managed in roll form because the partially cut or partially separated portions 20 are protected by the first liner 30 and the second liner layer 31 and do not tangle, and the filler can be manufactured in an automated manner directly together with the first liner layer 30 and the second liner layer 31.

[0087] Preferably, the first lining layer 30 and the second lining layer 31 are each defined by a fabric with a weight of about 10 g / m² to about 300 g / m².

[0088] Preferably, the first lining layer 30 and the second lining layer 31 are thin coverings.

[0089] The first lining layer 30 and the second lining layer 31 may have the function of keeping the partially cut portion 30 in a raised state and / or protruding from the corresponding surfaces 15, 16 of the sheet 12.

[0090] As mentioned, the filling material can form part of a structure used in the garment industry, which includes additional layers, particularly a first layer 101 and a second layer 102 arranged opposite to each other and defining an inner cavity 105, and wherein the filling materials 10a, 10a are arranged in the inner cavity 105.

[0091] According to a preferred aspect, layers 101 and 102 of the structure used in the garment industry can respectively contact the first lining layer 30 and the second lining layer 31 of the sheet 12, for example by gluing or sewing or generally by direct or indirect connection.

[0092] Alternatively, preferably, the first lining layer 30 and the second lining layer 31 are the outer fabric of the sheet 12, for example, overlapping with the layers of the garment.

[0093] The first layer 101 may be a layer intended to form an inner lining, while the second layer 102 may be a layer intended to form an outer cover.

[0094] This structure can be part of clothing 100 (such as a casual jacket, sports jacket, mountaineering jacket, or a pair of trousers intended for the same area of ​​use, as well as any other wearable articles that require an insulating component).

[0095] The filler described above can be very easily obtained from a sheet 12 having a first surface 15 and a second surface 16, wherein the first surface and the second surface are two surfaces located on opposite sides. The sheet is cut to define a portion of the cut portion that is connected to the rest of the sheet through a corresponding connecting region.

[0096] Finally, it is conceivable to shift or lift the portion of the cut section so that it protrudes from at least one of the first surface 15 and the second surface 16 of the sheet 12.

[0097] Furthermore, it is envisioned to provide a first liner layer 30 attached to a first surface 15 of the sheet 12 and a second liner layer 31 attached to a second surface 16 of the sheet 12. For example, the first liner layer 30 and the second liner layer may be attached to the first surface 15 and the second surface 16 of the sheet 12 by gluing or other similar or equivalent processes, respectively.

[0098] The arrangement of the first lining layer 30 and the second lining layer 31 can be carried out manually or through automated or mechanized operation.

[0099] Fillers 10 and 10a can be the fillers mentioned above.

[0100] The subject matter of this disclosure has been described so far with reference to its embodiments. It should be understood that other embodiments related to the same inventive concept may exist, all of which fall within the protection scope of the appended claims.
