Description

Method for Lifting the Hem of Clothing, Method for Manufacturing a Hem-Taping and Hem-Taping

[0001] This specification relates to a method for lifting the hem of clothing, a method for manufacturing a hem-taping, and a hem-taping. Specifically, a method for lifting the hem of clothing, a method for manufacturing a hem-taping, and a hem-taping capable of firmly adhering the hem-lifted portion of clothing with a simple procedure are disclosed.

[0002] In clothing such as trousers and skirts, to adjust the length, a method of folding back the hem to form a hem-lifted piece and securing it to the body of the clothing with a hem-taping is commonly used.

[0003] For example, in the hem-taping described in Patent Document 1, a single-sided coating layer is provided on the tape body, and a low-melting-point hot-melt adhesive layer is provided on the entire surface of the coating layer. The tape body is ironed, and the melted adhesive adheres the tape body across the hem-lifted piece and the body of the clothing to fix the edge of the hem-lifted piece.

[0004] Japanese Patent Application Laid-Open No. 2001-288428

[0005] However, in the hem-taping described in Patent Document 1, the fixing force by the melted adhesive is insufficient, and there is a risk that the hem-lifted piece may peel off over time.

[0006] The present invention was conceived in view of the above points, and an object thereof is to provide a method for lifting the hem of clothing, a method for manufacturing a hem-taping, and a hem-taping capable of firmly adhering the hem-lifted portion of clothing with a simple procedure.

[0007] This specification discloses the following embodiments. One embodiment relates to a method for hemming a garment. The hemming method involves combining a first tape body having a first adhesive layer made of a thermoplastic adhesive that generates adhesive force in a first temperature range on both sides, and a second tape body having a second adhesive layer made of a predetermined adhesive that generates adhesive force in a second temperature range with a lower limit higher than the lower limit temperature of the first temperature range and including a temperature range that overlaps with the first temperature range, to form a hem tape, and fixing the hem portion of the garment with the hem tape, comprising a tape joining step of bringing one side of the first tape body together with the side of the second tape body on which the second adhesive layer is provided, and melting the other side of the first tape body and the second tape so as to melt only the first adhesive layer. The method comprises: a first heating step of heating the tape body from at least one side opposite to the side of the tape body on which the second adhesive layer is provided, using a heating means at a temperature within the first temperature range and not overlapping with the second temperature range, thereby bonding the first tape body and the second tape body to form the hem tape; a tape placement step of positioning the other side of the first tape body of the hem tape in contact with the area spanning the hem piece of the garment and the main body of the garment; and a second heating step of heating and pressurizing the hem tape from the side of the second tape body on which the second adhesive layer is provided, using a heating and pressurizing means at a temperature that overlaps with the first and second temperature ranges, thereby bonding the hem tape to the garment.

[0008] In the tape joining process, one side of the first tape body is joined with the side of the second tape body on which the second adhesive layer is provided. In the first heating step, the other side of the first tape body and the side of the second tape body opposite to the side on which the second adhesive layer is provided are heated using a heating means at a temperature within a first temperature range, which does not overlap with the second temperature range, so that only the first adhesive layer melts. This adheres the first tape body and the second tape body together, forming a hem tape. By heating with a heating means at a temperature within a first temperature range, which does not overlap with the second temperature range, no adhesive force is generated in the second adhesive layer, and only the first adhesive layer provided on both sides of the first tape body is melted (thermally melted), thereby generating adhesive force. In particular, the thermoplastic adhesive on one side can be melted (thermally melted) to adhere the first tape body and the second tape body together and integrate them. The first temperature used here is one at which the predetermined adhesive constituting the second adhesive layer does not melt. This allows the first tape body to be bonded to the second tape body solely by the adhesive strength of the first adhesive layer, without melting the second adhesive layer. The heating means only needs to be able to heat the first tape body, and can be a contact or non-contact heating method.

[0009] In the tape placement process, the other side of the first tape body of the hem tape is placed in contact with the area spanning the hem piece of the garment and the main body of the garment. In the second heating process, the hem tape is heated and pressurized from the side of the second tape body of the hem tape opposite to the side where the second adhesive layer is provided, using a heating and pressurizing means at a second temperature which overlaps the first and second temperature zones. By bonding the hem tape to the garment, the hem tape can be bonded to the hem piece of the garment and the main body of the garment, and the hem piece can be fixed to the main body. By heating with a heating and pressurizing means at a second temperature which overlaps the first and second temperature zones, the predetermined adhesive of the second adhesive layer is melted, and the hem tape can be strongly bonded to the garment. By melting the thermoplastic adhesive of the first adhesive layer provided on both sides of the first tape, the melted adhesive of the first adhesive layer, together with the predetermined adhesive of the second adhesive layer, generates adhesive force to the garment, thereby increasing the adhesive strength of the hem tape. The adhesive of the first adhesive layer and the predetermined adhesive also function as primers to enhance their adhesion to each other, thereby significantly increasing the adhesion strength of the hem tape to the garment. More specifically, the thermoplastic adhesive on the other side of the first tape melts and penetrates into the fabric of the hem piece and the fabric of the garment's main body, integrating the fabric surfaces. Then, the thermoplastic adhesive on one side of the first tape and the adhesive of the second tape melt simultaneously, creating a state where they readily accept each other, resulting in strong adhesion and allowing them to exert a primer effect on each other.

[0010] In one embodiment, a release liner is attached to the other surface of the first tape body, and in the first heating step, when heating is performed with a heating means from at least one of the upper surface of the release liner and the side of the second tape body opposite to the side on which the second adhesive layer is provided, for example, when the heating means contacts the first tape body to heat, the melted adhesive of the first adhesive layer does not adhere to the heating means side but adheres to the release liner side, making the heating process easier.

[0011] If no release paper is attached, in the first heating step, if a heat-resistant sheet is placed on the other side of the first tape body and heated by a heating means from at least one side of the sheet's upper surface and the side of the second tape body opposite to the side on which the second adhesive layer is provided, for example, when the heating means contacts the first tape body to heat, the melted adhesive of the first adhesive layer adheres to the sheet side and not to the heating means side, making the heating process easier.

[0012] In one embodiment, the second tape body has a second adhesive layer provided only in a predetermined width. In the first heating step, if the heating means heats an area of ​​the second tape body that does not correspond to the predetermined width, the area of ​​the second adhesive layer on the second tape body is limited. By heating while avoiding this area, the adhesive of the first adhesive layer on the first tape body can be melted. With this embodiment, even if the temperature of the heating means is heated to a relatively high temperature, the adhesive of the first adhesive layer can be firmly melted without melting the predetermined adhesive of the second adhesive layer, thereby adhering the first tape body to the second tape body.

[0013] In one embodiment, the second tape body has a second adhesive layer provided only in a predetermined width, and before the first heating step and after the tape joining step, the area of ​​the second tape body that does not correspond to the predetermined width is heated by a heating means at a temperature higher than the upper limit temperature of the first temperature range and for a heating time longer than a predetermined heating time, so as to cause the thermoplastic adhesive to lose its re-adhesion ability. In this case, the melted thermoplastic adhesive generates adhesive force during the first heating step and adheres the first tape body to the second tape body. In this case, even if heating is performed again afterward, it is possible to prevent the re-adhesion ability from being generated. This embodiment creates a non-adherent area between the hem portion of the garment and the main body, improving the flexibility of the fabric of the hem portion after the hem tape is attached. In other words, it becomes possible to finish the hem portion of the garment with a soft texture. The predetermined heating time refers to an appropriate heating time at a heating temperature that can reversibly melt and solidify the thermoplastic resin.

[0014] In one embodiment, if the second tape body has a second adhesive layer provided only over a predetermined width, and the first tape body is formed within a range corresponding to the predetermined width, the hem tape can be adhered to the garment mainly around the first tape body corresponding to the predetermined width, that is, within a limited range corresponding to the predetermined width, rather than the entire range of the second tape body. This embodiment creates an area between the hem portion of the garment and the main body that is not adhered, improving the flexibility of the fabric in the hem portion after the hem tape has been adhered. In other words, it becomes possible to finish the hem portion of the garment with a soft texture.

[0015] In one embodiment, the release paper has a heat-sensitive ink background, a first set of text information printed on the background in the same color as the release paper or in white, and a second set of text information printed in the same color as the heat-sensitive ink. In this embodiment, the first set of text information and the second set of text information can be switched and displayed on the release paper before and after heating from above. For example, before heating the release paper with an iron, the first set of text information, "Heat evenly throughout," can be displayed. When the release paper is heated with an iron, the heat-sensitive ink background disappears, the first set of text information also disappears, and the second set of text information, "Caution: High Temperature," can be displayed on the release paper. In this way, in this embodiment, it is possible to switch and display text information with different content according to the heating process.

[0016] One embodiment relates to a method for manufacturing hemming tape. The manufacturing method comprises a tape fitting step of aligning one side of a first tape body, which has a first adhesive layer made of a thermoplastic adhesive that generates adhesive force in a first temperature range, with the side of a second tape body on which the second adhesive layer is provided, which has a second adhesive layer made of a predetermined adhesive that generates adhesive force in a second temperature range that has a lower limit higher than the lower limit temperature of the first temperature range and includes a temperature range that overlaps with the first temperature range, provided on at least one side of one of the tape body, with the second adhesive layer provided on the second tape body; and a tape bonding heating step of heating the other side of the first tape body and the side of the second tape body opposite to the side on which the second adhesive layer is provided with a heating means at a temperature in the first temperature range and that does not overlap with the second temperature range, so as to melt only the first adhesive layer, thereby bonding the first tape body and the second tape body.

[0017] In the tape joining step, one side of a first tape body, which has a first adhesive layer made of a thermoplastic adhesive that generates adhesive force in a first temperature range, provided on both sides, is joined with the side of a second tape body, which has a second adhesive layer made of a predetermined adhesive that generates adhesive force in a second temperature range, with a lower limit higher than the lower limit temperature of the first temperature range and including a temperature range that overlaps with the first temperature range, provided on at least one side of one side of the second tape body for a predetermined width. In the tape bonding heating step, heating is performed from at least one of the other side of the first tape body and the side of the second tape body opposite to the side provided with the second adhesive layer, using a heating means at a temperature within the first temperature range and not overlapping with the second temperature range, so that only the first adhesive layer melts, thereby bonding the first tape body and the second tape body to form a hem tape. Furthermore, by heating with a heating means at a temperature within the first temperature range that does not overlap with the second temperature range, adhesive force is not generated in the second adhesive layer, and only the first adhesive layers provided on both sides of the first tape body are melted (thermally melted), thereby generating adhesive force. In particular, the thermoplastic adhesive on one side can be melted (thermally melted), allowing the first tape body and the second tape body to be bonded and integrated.

[0018] One embodiment relates to a method for hemming clothing. The hemming method involves fixing the hem portion of clothing with a hemming tape, which is formed by bonding one side of a first tape body having a first adhesive layer made of a thermoplastic adhesive that generates adhesive force in a first temperature range on both sides, and one side of a second tape body having a second adhesive layer made of a predetermined adhesive that generates adhesive force in a second temperature range with a lower limit higher than the lower limit temperature of the first temperature range and including a temperature range that overlaps with the first temperature range, to at least one side of the second tape body. The method comprises a tape placement step of positioning the other side of the first tape body of the hemming tape in contact with the area spanning the hem piece of the clothing and the main body of the clothing, and a tape application heating step of heating and pressurizing the hemming tape from the side of the second tape body opposite to the side on which the second adhesive layer is provided, using a heating and pressurizing means at a second temperature which is a temperature that overlaps with the first and second temperature ranges, to bond the hemming tape to the clothing.

[0019] In the tape placement step, the other side of the first tape body of the hem tape is placed in contact with the area spanning the hem piece of the garment and the main body of the garment. In the tape application heating step, the side of the second tape body of the hem tape opposite to the side on which the second adhesive layer is provided is heated and pressurized using a heating and pressing means at a second temperature, which is a temperature that overlaps between the first and second temperature zones, thereby bonding the hem tape to the garment. This allows the hem tape to adhere to the hem piece of the garment and the main body of the garment, and fix the hem piece to the main body. At this time, by heating and pressurizing using a heating and pressing means at a second temperature, which is a temperature that overlaps between the first and second temperature zones, the predetermined adhesive of the second adhesive layer is melted, and the hem tape can be strongly bonded to the garment. In this embodiment, by melting the thermoplastic adhesive of the first adhesive layer provided on both sides of the first tape, the adhesive of the first adhesive layer, together with the predetermined adhesive of the second adhesive layer, generates adhesive force to the garment, thereby increasing the adhesive strength of the hem tape. The adhesive of the first adhesive layer and the predetermined adhesive also function as primers that enhance each other's adhesion, thereby sufficiently increasing the adhesive strength of the hem tape to the garment. More specifically, the thermoplastic adhesive on the other side of the first tape melts and penetrates into the fabric of the hem piece and the fabric of the garment's main body, integrating the fabric surfaces. The thermoplastic adhesive on one side of the first tape and the adhesive of the second tape melt simultaneously, making them more receptive to each other, resulting in strong adhesion and allowing them to exert a primer effect on each other.

[0020] One embodiment relates to a hem tape. The hem tape comprises a first tape body having a first adhesive layer on both sides made of a thermoplastic adhesive that generates adhesive strength in a first temperature range, and a second tape body having a second adhesive layer on at least one side of a predetermined width made of a predetermined adhesive that generates adhesive strength in a second temperature range having a lower limit temperature higher than the lower limit temperature of the first temperature range and including a temperature range that overlaps with the first temperature range, with the one side of the second tape body being adhered to the first tape body.

[0021] In this embodiment, since the first tape body is provided with a first adhesive layer made of a thermoplastic adhesive on both sides, for example, the first tape body can be bonded to the second tape body via the adhesive of the first adhesive layer on one side of the first tape body, thereby creating a structure in which the two tapes are integrated.

[0022] In this embodiment, the second tape body has a second adhesive layer provided on at least one side of a predetermined width, which consists of a predetermined adhesive that generates adhesive force in a second temperature range that has a lower limit higher than the lower limit temperature of the first temperature range and includes a temperature range that overlaps with the first temperature range. As a result, the hem portion of the garment can be adhered to the main body of the garment and fixed in place via the predetermined adhesive of the second adhesive layer and the adhesive of the first adhesive layer on the other side of the first tape body.

[0023] In this embodiment, the first tape body is provided with a first adhesive layer made of a thermoplastic adhesive that generates adhesive strength in a first temperature range, and the second tape body is provided with a second adhesive layer made of a predetermined adhesive that generates adhesive strength in a second temperature range, with a lower limit higher than the lower limit temperature of the first temperature range and including a temperature range that overlaps with the first temperature range. As a result, the adhesive of the first adhesive layer, together with the adhesive of the second adhesive layer, generates adhesive strength to the garment, thereby increasing the adhesive strength of the hem tape. The adhesive of the first adhesive layer and the predetermined adhesive also function as primers that enhance each other's adhesion, thereby sufficiently increasing the adhesive strength of the hem tape to the garment. More specifically, the thermoplastic adhesive on the other side of the first tape body melts and penetrates into the fabric of the hem piece and the fabric of the main body of the garment, integrating the fabric surfaces. Then, the thermoplastic adhesive on one side of the first tape body and the adhesive of the second tape body melt simultaneously, becoming receptive to each other, resulting in strong adhesion and allowing them to exert a primer effect on each other.

[0024] In one embodiment, the first tape body has release paper attached to the side opposite to the side that is adhered to the second tape body, thereby preventing foreign matter, dirt, etc. from adhering to the thermoplastic adhesive on the side of the first tape body opposite to the side that is adhered to the second tape body.

[0025] In one embodiment, the second tape body has a second adhesive layer provided only in a predetermined width. In this embodiment, when the second tape body is bonded to the first tape body in a range that does not correspond to the predetermined width, it becomes possible to select the material of the first tape body regardless of the melting temperature of the second adhesive layer. In other words, not only materials that melt at a temperature lower than the melting temperature of the second adhesive layer can be used, but also materials that melt at a relatively high temperature, thereby broadening the range of material selection for the first tape body.

[0026] In one embodiment, the second tape body has a second adhesive layer provided only over a predetermined width. In this embodiment, if the first tape body is formed within a range corresponding to the predetermined width, the hem tape can be adhered to the garment mainly around the first tape body corresponding to the predetermined width, that is, within a limited range corresponding to the predetermined width, rather than the entire range of the second tape body. According to this embodiment, an area that is not adhered is created between the hem portion of the garment and the main body, which improves the flexibility of the fabric of the hem portion after the hem tape has been adhered. In other words, it becomes possible to finish the hem portion of the garment with a soft texture. In addition, a step is created between the hem portion of the garment and the main body due to the difference in thickness, but by not adhering the hem tape to this step, the step can be made invisible from the side of the hem tape.

[0027] The method for hemming clothing is a simple procedure that allows for a strong bond to the hem of the garment. The manufacturing method for hemming tape is a simple procedure that allows for a strong bond to the hem of the garment. Hemming tape allows for a strong bond to the hem of the garment using a simple procedure.

[0029] The embodiments will be described below with reference to the drawings. The following describes a method for hemming clothing, a method for manufacturing hemming tape, and an example of hemming tape, and the present invention is not limited to the embodiments disclosed in the specification, and can be modified as appropriate.

[0030] In the following explanation, using Figure 1(a) as a reference, the top of the figure will be referred to as "up" or "above," and the bottom of the figure will be referred to as "down" or "below."

[0031] As shown in Figure 1(a), an example of a hem tape, hem tape A comprises a heat-pressure double-sided tape 1 and a main tape 2.

[0032] Here, the heat-pressure double-sided tape 1 comprises a tape-like member consisting of a first adhesive layer made of the first adhesive on at least both sides of the tape (the top surface and the bottom surface, represented by reference numerals 11 and 12, respectively). As an example, the heat-pressure double-sided tape 1 is a member formed into a tape shape from an adhesive component that melts when heated (hot-melt type). That is, the entire heat-pressure double-sided tape 1 is made of the first adhesive. In Figure 1(a), a release paper 3 is attached to the top surface of the heat-pressure double-sided tape 1. That is, a layer of release paper 3 is provided on top of the first adhesive layer. The release paper 3 is, for example, paper that has undergone a release treatment, and before heating it is held in close contact with the adhesive layer without the need for other adhesives, and can be easily peeled off by hand when in use.

[0033] The first adhesive in this first adhesive layer is a thermoplastic adhesive that melts (thermal melting) at a temperature of approximately 110°C to 160°C and solidifies after cooling. Furthermore, the temperature range in which the first adhesive melts partially overlaps with the temperature range in which the second adhesive layer 20, described later, melts (140°C to 160°C).

[0034] For example, the first adhesive only needs to have the property of being able to melt due to the action of heat and solidify after cooling multiple times. As the first adhesive, for example, polyamide (PA) type, polyester (PES) type, copolyester (Co-PES) type, polyamide copolymer (Co-PA) type, polyurethane (PU, TPU) type, ethylene vinyl acetate (EVA) type, polyolefin (PO) type (atactic polypropylene (APP), amorphous polyalphaolefin (APAO), ethylene-ethyl acrylate copolymer (EEA), etc.), styrene block copolymer (SBS, etc.), acrylic hot melt, acrylic block copolymer, thermoplastic elastomer (TPE) type, polyvinyl butyral (PVB) type, nylon hot melt (PA6, PA66), thermoplastic polyether ester (TPEE) type, ethylene-methacrylic acid copolymer (EMAA) type, ethylene-vinyl acetate copolymer (EVA), polyester, polyurethane (thermoplastic grade), thermal polymer (composite resin type), etc. can be used. Furthermore, the type of the first adhesive is preferably selected appropriately depending on the material of the clothing and its compatibility with the second adhesive layer 20. The first adhesive layer is preferably in the form of a sheet having a web structure (spiderweb structure), a nonwoven fabric (felt), etc.

[0035] The heat-pressure double-sided tape 1 does not necessarily have to be a member formed by forming the first adhesive in the shape of a tape. For example, it can also be a tape-shaped member in which a first adhesive layer made of the first adhesive is provided on the upper and lower surfaces of a heat-resistant base material (such as a cloth or a film made of polyester). Here, the melting point of the base material must be higher than the melting points of the first adhesive layer and the second adhesive layer.

[0036] The main tape 2 has a second adhesive layer 20 made of a second adhesive on the upper surface of the base material (see Figure 1(a)). In addition, two of the second adhesive layers 20 are provided for one base material, each formed in a strip shape with a predetermined width, preferably a constant width, along the longitudinal direction of the base material. As the base material of the main tape 2, for example, polyester woven fabrics (textiles), knitted fabrics (stretch materials), nonwoven fabrics, etc. can be used. Here, the melting point of the base material must be higher than the melting points of the first adhesive layer and the second adhesive layer.

[0037] The second adhesive constituting the second adhesive layer 20 is an adhesive that melts at a higher temperature range than the temperature required for bonding the heat-pressure double-sided tape 1 and the main tape 2, in order to ensure the adhesive strength when bonding the hem tape A to the garment. In other words, the second adhesive is an adhesive whose adhesive function is not affected by the heating required for bonding the heat-pressure double-sided tape 1 and the main tape 2. The type of the second adhesive is preferably selected appropriately depending on its compatibility with the adhesive and substrate of the first adhesive layer. The second adhesive differs from the first adhesive in terms of melting, activation, melting temperature range, and its role as an adhesive. The first adhesive melts at a relatively low temperature, penetrates into the garment fabric, and can withstand reheating. Its main purpose is to penetrate the fabric surface and into the fibers to "adhere." In contrast, the second adhesive functions at a higher temperature range and is intended to firmly fix garment components together. It has the property of completing bonding with a single heating. The second adhesive is preferably a thermoplastic resin, but as a variation, a water-dispersible thermoactivated adhesive may also be used. The second adhesive is preferably a hot-melt type and has a filament structure. The second adhesive may or may not require water to exhibit its adhesive function. The second adhesive can be selected from known thermoplastic resins and water-dispersible thermoactivated adhesives. For example, polyamide resins, polyester resins, polyurethane resins, etc. can be used as the second adhesive.

[0038] Thermoplastic resins are resins that do not require water in the bonding reaction. Examples of thermoplastic resins include low-melting-point polyester resins and low-melting-point polyamide resins. Low-melting-point polyester resins have a melting point lower than that of ordinary polyester resins (usually 250°C or higher) (for example, around 110°C to 190°C, preferably around 140°C to 160°C). Low-melting-point polyamide resins have a melting point lower than that of ordinary polyamide resins (usually 250°C or higher) (for example, 200°C or lower, for example, around 140°C to 180°C, preferably around 140°C to 160°C).

[0039] Water-dispersible, heat-activated adhesives are adhesives in which, at least when brought into contact with water and heated during use, the solid adhesive components disperse in water, and adhesive strength is achieved through evaporation of water and thermal activation.

[0040] When a water-dispersible thermoactivated adhesive is heated in the presence of water, the molecular structure of the adhesive components changes, and thermal activation occurs, strengthening the chemical bonds. Furthermore, thermal activation generates strong adhesive force, and the adhesive can fully cure, exhibiting high adhesive strength. Examples of water-dispersible thermoactivated adhesives include water-dispersible polyurethane-based thermoactivated adhesives, water-dispersible polyamide-based thermoactivated adhesives, and water-dispersible polyester-based thermoactivated adhesives. The melting point of the thermoactivated component contained in the water-dispersible thermoactivated adhesive is, for example, about 140°C to 200°C, preferably about 140°C to 180°C, and more preferably about 140°C to 160°C.

[0041] If the second adhesive is a thermoplastic resin, contacting it with water and heating it to a temperature of approximately 140°C to 160°C can help to bond the second adhesive to the fabric of the garment and assist in heat conduction during heating. If the second adhesive is a water-dispersible thermoactivated adhesive, contacting it with water and heating it to a temperature of approximately 140°C to 160°C can enable water-dispersible thermoactivation.

[0042] The second adhesive layer 20 does not necessarily need to be formed in a strip shape with a constant width along the longitudinal direction of the base material, and it is not necessary to provide two for one base material. For example, a structure in which the second adhesive layer 20 is provided along the entire upper surface of the base material can also be adopted. However, by providing the second adhesive layer 20 in a strip shape with a constant width along the longitudinal direction of the base material with the main body tape 2, a range without the second adhesive layer 20 is formed on the upper surface of the base material. When the thermocompression double-sided tape 1 is adhered to the main body tape 2, the range can be heated at a higher temperature to reduce the influence of heat on the second adhesive layer 20 while firmly melting the first adhesive layer.

[0043] The sizes of the thermocompression double-sided tape 1 and the main body tape 2 are not particularly limited. However, considering that the main body tape 2 is heated and its size shrinks, it is preferable to form the size of the thermocompression double-sided tape 1 slightly smaller than the size of the main body tape 2. Thereby, even if the main body tape 2 shrinks due to heating, it is possible to prevent the thermocompression double-sided tape 1 from protruding from the main body tape 2 and the iron from being contaminated by the melted first adhesive layer.

[0044] The release paper 3 has an arbitrary configuration. However, since the melted first adhesive layer adheres to the release paper 3 when the thermocompression double-sided tape 1 is heated, and it is possible to prevent the iron from being contaminated, it is preferable that the release paper 3 is attached to the upper surface 11 of the thermocompression double-sided tape 1. Further, as will be described later, by wetting the hem-raising tape A and corresponding to the part heated by the iron I to peel off the release paper 3, the moisture is held by the release paper 3, and the hem-raising tape A secures the moisture necessary for the activation of the heat dissipation of the adhesive force due to water dispersion, and it is possible to prevent poor adhesion due to insufficient moisture. Therefore, it is preferable that the release paper 3 is attached to the upper surface 11 of the thermocompression double-sided tape 1.

[0045] Next, an example of the manufacturing method of the hem-raising tape A will be described.

[0046] As shown in Fig. 1(a), prepare the thermocompression double-sided tape 1 with the release paper 3 attached and the main body tape 2.

[0047] Next, with the side (upper surface 11 side) of the heat-press double-sided tape 1 to which the release paper 3 is attached facing upward, the lower surface 12 of the heat-press double-sided tape 1 is placed on the upper surface of the main body tape 2 (see Fig. 1(b)). At this time, the lower surface 12 of the heat-press double-sided tape 1 abuts on the position of the second adhesive layer 20.

[0048] Subsequently, as shown in Fig. 2(a), an iron I set to a temperature of about 110°C to 130°C is brought into contact with and heated from above the release paper 3. By heating the iron I, only the first adhesive layer of the heat-press double-sided tape 1 melts to generate an adhesive force.

[0049] By heating the heat-press double-sided tape 1 along the heat-press double-sided tape 1 from above the release paper 3 with the iron I, the lower surface of the heat-press double-sided tape 1 adheres to and integrates with the upper surface of the main body tape 2 due to the adhesive force of the melted first adhesive layer, and the hem-raising tape A is formed (see Fig. 2(b)). The adhesion here does not need to exert the original adhesive force of the heat-press double-sided tape 1, and it is sufficient that the heat-press double-sided tape 1 and the main body tape 2 are integrated.

[0050] In the heating by the iron I, by heating at a temperature of about 110°C to 130°C, the first adhesive layer is melted, but by heating in the same temperature range, it is possible to prevent the second adhesive layer 20 of the main body tape 2 from melting due to heat. Thereby, the adhesive force of the second adhesive layer 20 when the hem-raising tape A is adhered to the clothing can be ensured.

[0051] Here, when heating the heat-press double-sided tape 1 from above the release paper 3, it is not necessarily required to use an iron. As long as heating is possible, it is not limited to contact or non-contact, and known heating means can be adopted. However, when using the water-dispersion type heat-activated adhesive of the second adhesive layer 20 of the main body tape 2, it is necessary to adopt a heating means that does not generate moisture as the heating means for heating the heat-press double-sided tape 1 from above the release paper 3.

[0052] As another embodiment, when heating the heat-press double-sided tape 1 along the heat-press double-sided tape 1 from above the release paper 3 with the iron I, it is also possible to further heat the portion corresponding to the range without the second adhesive layer 20 in the heat-press double-sided tape 1 at a higher temperature to lose the re-adhesive force of the first adhesive layer.

[0053] In this case, heating is performed under conditions in which the first polyamide adhesive layer does not reversibly generate adhesive force, for example, heating at a high temperature (higher than 160°C) that exceeds the optimal operating temperature for melting the adhesive components, or heating at or above the optimal operating temperature for a long time that exceeds the optimal heating time for melting the adhesive components. Due to this heating, the adhesive components of the first adhesive layer generate adhesive force only when the heat-pressure double-sided tape 1 adheres to the main tape 2, and in subsequent processes, heating will not generate any adhesive force.

[0054] In this embodiment, when the hem tape A is later attached to the trousers P, the adhesive strength of the first adhesive layer is not generated, resulting in areas where the hem tape A does not adhere to the trousers P. This improves the flexibility of the fabric in the hem portion after the hem tape has been attached. In other words, it becomes possible to finish the hem portion of the garment with a soft texture. Thus, in order to increase the flexibility of the fabric, it is also possible to use the first adhesive layer in a way that partially reduces its adhesive strength.

[0055] Next, we will explain an example of a method for hemming clothing using hemming tape A.

[0056] As shown in Figure 3(a), for the trousers P to be hemmed, the trousers P are turned inside out, the hem portion is folded back to create a hem piece P1 of the desired hemmed length, and the hem piece P1 is then heated with an iron to set the shape.

[0057] Furthermore, the hem tape A described above is soaked in water, and the hem tape A is positioned so that the side with the release paper 3 (the upper surface 11 of the heat-pressure double-sided tape 1) contacts the end of the hem piece P1 of the trousers P (the end opposite to the folded portion) and the main body P2 of the trousers (see Figure 3(b)).

[0058] Next, with respect to the hem tape A, which is positioned to straddle the end of the hem piece P1 and the main body P2, the release paper 3 is peeled off and an iron I, set to a temperature of approximately 140°C to 160°C, is applied to the underside of the main body tape 2 (the side opposite to the side with the second adhesive layer 20) to heat and pressurize the hem tape A (see Figure 3(c)). That is, the release paper 3 is peeled off in accordance with the area being heated by the iron I.

[0059] Here, when the hem tape A, which has been soaked in water, is brought into contact with the trousers P, the release paper 3 is kept attached until just before heating with the iron I, thereby retaining moisture with the release paper 3. As a result, moisture is less likely to be absorbed into the fabric of the trousers P, ensuring that the hem tape A has the moisture necessary for water-dispersion heat activation to generate adhesive strength, and preventing poor adhesion due to insufficient moisture.

[0060] The heating of the iron I activates the second adhesive layer 20 of the main tape 2 through water dispersion heat, and the pressure from the iron I causes it to penetrate the fabric of the trousers P. As the heated temperature drops while the molten adhesive is intricately intertwined, the adhesive components solidify in their complex shape, creating a strong adhesive force that allows the hem tape A to adhere to the hem piece P1 and the main body P2. Furthermore, the pressure pushes the adhesive into the interior of the base material of the main tape 2, and the adhesive penetrates both the interior of the base material and the interior of the trousers fabric, thereby increasing the adhesive strength.

[0061] Furthermore, the heating and pressurizing of the iron I melts the first adhesive layer of the heat-pressure double-sided tape 1, allowing the adhesive of the first adhesive layer on the side from which the release paper 3 has been peeled to penetrate into the fabric of the hem piece P1 and the main body P2, integrating the inside and surface of the fabric. In addition, the adhesive of the first adhesive layer and the adhesive of the second adhesive layer on the side of the heat-pressure double-sided tape 1 opposite to the side with the release paper 3 melt together due to the heating, creating a primer effect that makes them more receptive to each other's adhesive layers, allowing them to adhere strongly to one another.

[0062] In this way, by heating and pressing the hem tape A with an iron I, the hem tape A is firmly adhered to the trousers P, thereby firmly fixing the hem piece P1 to the main body P2, and the trousers P can be hemmed (see Figure 3(d)).

[0063] Here, it is not necessarily required to use an iron when heating the hem tape A from the underside of the main tape 2 while peeling off the release paper 3. Any known heating method that can heat and pressurize can be used. For example, a heating press machine can be used.

[0064] In hemming tape A, a heat-pressure double-sided tape 1 having a first adhesive layer made of thermoplastic adhesive and a main tape 2 having a second adhesive layer 20 made of water-dispersible thermoactive adhesive are combined to firmly adhere the hemming tape A to the desired hem portion of the trousers P.

[0065] When hemming using this hemming tape A, the hemming piece P1 is less likely to peel off the main body P2 of the trousers P even after time has passed, and strong fixation can be achieved for a long period of time.

[0066] Next, a modified example of the hem tape A described above will be explained.

[0067] In the hem tape A1 shown in Figure 4(a), when the lower surface 12 of the heat-pressure double-sided tape 1 is adhered to the upper surface of the main tape 2, the lower surface 12 of the heat-pressure double-sided tape 1 is attached to the area 21 where the second adhesive layer 20 is not provided.

[0068] In this hem tape A1, when the heat-pressure double-sided tape is heated with an iron, the heating is performed in an area without the second adhesive layer 20. Therefore, it is possible to select the material of the heat-pressure double-sided tape 1 regardless of the melting temperature of the second adhesive layer 20. In other words, not only materials that melt at a temperature lower than the melting temperature of the second adhesive layer 20 can be used, but also materials that melt at a relatively high temperature, thus broadening the range of material selection for the heat-pressure double-sided tape 1. Furthermore, by broadening the range of material selection for the heat-pressure double-sided tape 1, the range of material selection for the second adhesive layer 20 can also be broadened. In addition, the adhesive components of the second adhesive layer 20 can not be melted, and only the adhesive of the first adhesive layer can be firmly melted, allowing the heat-pressure double-sided tape 1 to adhere to the main tape 2.

[0069] As another variation, in the hem tape A2 shown in Figure 4(b), two heat-pressure double-sided tapes 10 are attached to one main tape 2. The heat-pressure double-sided tape 10 has a first adhesive layer on both sides, and its size is formed to be larger than the second adhesive layer 20. Also, taking into account that the base material of the main tape 2 shrinks due to heat, the heat-pressure double-sided tape 10 is formed to be smaller than the base material of the main tape 2.

[0070] In this hem tape A2, the area where the heat-pressure double-sided tape 10 is applied is attached to the hem piece P1 and the main body P2 separately, sandwiching the end of the hem piece P1 of the trousers opposite the folded portion. As a result, there is a non-adherent area between the hem tape A2 and the hem piece P1 and the main body P2. Consequently, the bending and twisting forces applied to the trousers P can be blocked, the flexibility of the fabric can be ensured, and the hem of the garment can be finished with a soft texture.

[0071] Thus, in the case of hemming tape, the area to which the heat-pressure double-sided tape adheres to the main tape may be the entire surface of the main tape or it may be limited to a specific area. It is sufficient as long as the structure is such that it can be attached to the garment as a single hemming tape in a later process. Examples of structures for applying heat-pressure double-sided tape to the main tape in a limited area include a structure in which the heat-pressure double-sided tape is applied discontinuously in the longitudinal or transverse direction of the main tape with a predetermined width corresponding to the main tape, or a structure in which it is applied in a dot pattern.

[0072] As another variation, the release paper of the hemming tape can be printed with text information using heat-sensitive ink. For example, the release paper 30 shown in Figure 5(a) can be used as the release paper to be attached to the upper surface of the heat-pressure double-sided tape 1.

[0073] This release paper 30 has a background 31 printed with black heat-sensitive ink on the upper surface of a substrate coated with a silicone polymer on paper or film, and white letters 32 are printed on the background 31 (see Figure 5(a)). In addition, black letters 33 are printed on a portion of the area on the upper surface of the substrate where the background 31 is provided (see Figures 5(b) and 5(c)).

[0074] The heat-sensitive ink in background 31 is a reversible heat-sensitive ink that becomes colorless and transparent in response to heat above 110°C and returns to black when the temperature drops.

[0075] When the heat-pressure double-sided tape 1 is heated with an iron and adhered to the main tape 2, the release paper 30, before heating, displays text information in white letters 32 on a black background 31 (in Figure 5(a), the text reads, "(1) Heat the entire surface evenly with an iron").

[0076] When the release paper 30 is heated with an iron, the heat-sensitive ink reacts to the heat, causing the black background 31 to disappear, and consequently the white letters 32 to vanish. In addition, black letters 33 appear in part of the area where the black background 31 has disappeared (see Figure 5(b)).

[0077] Once the entire release paper 30 has been heated by the iron, the black background 31 and the white lettering 32 disappear, and black lettering 33 appears on the release paper 30 (see Figure 5(c)). The text information of the black lettering 33 (in Figure 5(c), the words "Caution: High Temperature (2) Let it cool completely before working") is displayed.

[0078] In this way, the text information can be switched between white text 32 and black text 33 before and after heating, in accordance with the heating process on the release paper 30. Furthermore, by devising the content of the text information, it is possible to display work instructions and warning comments according to the heating status. In addition, by linking the ink reaction temperature with the work instruction temperature, it is possible to detect any heating leaks.

[0079] Further variations of the garment hemming method will be explained using diagrams. The following explanation describes a method using the heat-pressure double-sided tape 1 and main tape 2 described above.

[0080] First, as shown in Figure 6(a), the trousers P to be hemmed are turned inside out, the hem portion is folded back to create a hem piece P1 of the desired hemmed length, and the hem piece P1 is then shaped by heating and pressing it with an iron.

[0081] In Figures 6(a), 6(c), 6(d), 7(a), and 7(c), a schematic side cross-sectional view showing the structure of the trousers and various tapes is shown on the right side of the figure.

[0082] Next, position the heat-pressure double-sided tape 1 so that its lower surface (the side opposite to the side with the release paper 3) is in contact with the end of the hem piece P1 of the trousers P (the end opposite to the folded portion) and the main body P2 of the trousers (see Figure 6(b)).

[0083] Next, the heat-pressure double-sided tape 1, which is positioned to straddle the end of the hem piece P1 and the main body P2, is heated and pressurized by applying an iron I, set to a temperature of approximately 140°C to 160°C, to the release paper 3 on its upper surface (see Figure 6(c)).

[0084] The heating and pressurizing of the iron I melts the first adhesive layer on both sides of the heat-pressure double-sided tape 1, penetrating into the fabric of the hem piece P1 and the main body P2 of the trousers P, and integrating the inside and surface of the fabric of the hem piece P1 and the main body P2.

[0085] In yet another modification, the release paper 3 is peeled off from the state in which the heat-pressure double-sided tape 1 is attached, so that only the heat-pressure double-sided tape 1 is adhered to the hem piece P1 and the main body P2 (see Figure 7(a)). In this case, the adhesive component of the first adhesive penetrates the fabric of the trousers P due to heating and pressurization, and as the temperature drops while the adhesive is intricately intertwined, the adhesive component solidifies, causing the adhesive component to penetrate into the interior of the fabric of the hem piece P1 and the main body P2, the surface of the fabric to be covered with the adhesive component, and the interior and surface of the fabric become one.

[0086] Next, while the residual heat from the heat-pressure double-sided tape 1 is still present, the main tape 2 is positioned so that its upper surface (the side with the second adhesive layer 20) is placed on top of the heat-pressure double-sided tape 1 (see Figure 7(b)).

[0087] Next, an iron I, set to a temperature of approximately 140°C to 160°C, is applied to the underside of the main tape 2 (the side opposite to the side on which the second adhesive layer 20 is provided) to heat and pressurize the main tape 2 (see Figure 7(c)).

[0088] The heating and pressurizing of the iron I causes the second adhesive layer 20 of the water-containing main tape 2 to be activated by the heat of water dispersion, generating a strong adhesive force. This allows the adhesive of the second adhesive layer 20 to bond with the adhesive components of the first adhesive, which are integrated with the interior and surface of the fabric of the hem piece P1 and the main body part P2.

[0089] In addition, by heating and applying pressure with iron I, the heat-pressure double-sided tape 1 and the main tape 2 are heated simultaneously, causing the adhesives on the contact surfaces to melt due to the heat, creating a primer effect that makes them more receptive to each other's adhesive layers, and allowing the adhesive layers to bond strongly to each other.

[0090] In this way, by simultaneously heating and applying pressure to the heat-pressure double-sided tape 1 and the main tape 2 with an iron I, the hem piece P1 and the main body P2 are firmly adhered to each other via the heat-pressure double-sided tape 1, thereby firmly fixing the hem piece P1 to the main body P2 and allowing the trousers P to be hemmed (see Figure 7(d)).

[0091] As described above, the method for hemming garments disclosed herein is a method that allows for the firm adhesion of the hemmed portion of garments using a simple procedure. Furthermore, the method for manufacturing hemming tape disclosed herein is a method that allows for the firm adhesion of the hemmed portion of garments using a simple procedure. Furthermore, the hemming tape disclosed herein allows for the firm adhesion of the hemmed portion of garments using a simple procedure.

[0092] Although the present invention has been described in detail based on the embodiments described above, it goes without saying that the present invention is not limited to the embodiments described above, and can be modified in various ways without departing from the spirit of the invention.

[0093] The following examples illustrate some of the effects of the present invention.

[0094] The following test was conducted using the above-mentioned hem tape A as an example and the above-mentioned main tape 2 as a comparative example. In the test, "PA23 Double-Sided Tape for Gram Cloth (for Paper, Film, and Composite Fabrics)" (Shanghai Qiyou Chemical Materials Co., Ltd.) (Purchase route: China 1688) was used for the first adhesive layer, and "Trouser Hemming Tape (Thread-like Adhesive Arrangement Type)" (Wenzhou Kangwang Textile Technology Co., Ltd.) (Purchase route: China 1688) was used for the second adhesive layer.

[0095] Five types of fabrics were prepared as test subjects to which the tapes of the examples and comparative examples were attached: Fabric 1 (72% polyester / 26% polyurethane), Fabric 2 (100% polyester), Fabric 3 (100% cotton), Fabric 4 (100% cotton (textured)), and Fabric 5 (100% polyester (brushed)). For each of these fabrics 1 to 5, the tapes of the examples and comparative examples were simultaneously heated and pressed with an iron (160°C) for 60 seconds to fix the tapes to each fabric. After that, the fabric was made vertical, and a hanging weight was attached to the upper end of each tape. The weight of the hanging weight was increased in 100g increments, and the weight at which the upper end of each tape peeled off in the opposite direction (vertically downward) was recorded. The same test was performed five times for each fabric. The test results are shown in Table 1 below. The values ​​such as "3.2" in Table 1 indicate the weight of the hanging weight (in kg) immediately before the upper end of the tape peeled off. In Table 1, "Average Value" is the average value of the results from five tests, and "Ratio to Comparative Example" shows the increase ratio of the "Average Value of the Example" to the "Average Value of the Comparative Example" for each fabric.

[0096]

[0097] As shown in Table 1, the values ​​for the example were greater than the comparative values ​​for all fabrics 1 to 5. This supports the idea that the tape in the example adhered more strongly to each fabric than the tape in the comparative example.
