Description

TECHNICAL AREA

[0001] The present disclosure and invention relate to substance, a material product and a method for producing the material product. BACKGROUND

[0002] With regard to clothing containing fabric made of thermally meltable yarns and other yarns, a technique is known in which the thermally meltable yarn is fused or melted by heat setting to provide, for example, an anti-fraying function for the fabric (see e.g. JP 2008-150749 A). SUMMARY OF THE INVENTION Problem to be solved

[0003] Since the aforementioned heat-setting process is carried out across the entire surface of the fabric, a single processed piece of fabric exhibits essentially uniform properties across its entire surface. Unfortunately, this fact severely limits the use or application of a single piece of fabric. That is to say, even if such a single piece of fabric is used, it is not possible to obtain a fabric product with a wide variety of designs.

[0004] It is therefore an object of the present disclosure and invention to provide a material with different properties, such as strength, hardness, texture, etc., in various areas, as well as a material product comprising the material, and a method for producing the material product, so that it is possible to provide a comprehensively designed material product with a variety of designs. Means to solve the problems

[0005] The present invention is defined by the attached independent claims 1 and 3, wherein the dependent claims describe optional features and preferred embodiments.

[0006] To solve the aforementioned problems, the present disclosure and invention provide a material comprising thermally fusible fibers and fibers with a higher melting point than the thermally fusible fibers in a predetermined ratio, wherein the material has a first region and a second region with a higher degree of fusion than the first region. The "material" in the present invention is also referred to as a textile and, in its technical conception, includes woven or nonwoven fabrics and knitted fabrics. It is preferred that a thermally fusible fiber consists of a core section and a sheath section, and that the sheath consists of a resin with a lower melting point than that of the core section and covers the outer circumference of the core section.

[0007] The material of the present invention can be produced by a process comprising the steps of: providing a material comprising thermally meltable fibers and fibers with a higher melting point than the thermally meltable fibers in a predetermined ratio (providing or preparing), and heating a predetermined region of the material to increase the degree of thermal fusion of that region compared to other regions (thermal fusion step). In this process, it is also preferred that a thermally meltable fiber consists of a core section and a sheath section, and that the sheath section consists of a resin with a lower melting point than the core section and covers the outer circumference of the core section.

[0008] Through the substance according to the invention and the method according to the invention for producing the substance with such a configuration, it is possible to provide a single substance with different properties depending on the region, since the degree of melting (i.e. the degree of fusion, fusion bonding or welding) is different in the first area and in the second area.

[0009] In the production of a material according to the present invention described above, it is preferred that a predetermined area of ​​the material is heated (heat-pressed), and the other areas are masked. Additionally or alternatively, it is preferred that, in the thermal melting step, the predetermined area of ​​the material is heated, while the other areas are folded to an opposite side with respect to an area to be fused in the predetermined area.

[0010] In the inventive method for producing a material with such a configuration, for example a hot press or a thermofixer can be used for thermal fusion, and in particular a special tool such as a die is not required, which makes thermal fusion easy to carry out.

[0011] The present invention also provides a fabric product comprising the material described above (i.e., a body comprising the material described above), wherein the second area is positioned in a region requiring higher strength than other areas. Examples of textile products include bags and clothing.

[0012] If the fabric product is, for example, a bag, the second area is a section located on the outer surface. If the fabric product is clothing, the second area is a section corresponding to at least a collar, a side panel (a boundary section between a front and a back panel), a hanger, a pocket, a skirt, a front leg, a front hem, a flap, a belt, and a belt loop. In other words, these sections are thermally bonded to form (three-dimensional) structural arrangements (shapes) within the respective fabric products, ensuring morphological stability, dimensional stability, and texture retention (feel, touch).

[0013] It is preferred that the inventive method for producing a fabric further includes a dyeing step for dyeing the fabric and / or a drying step for drying the fabric at a temperature below the melting point of the thermally fusible fiber.

[0014] The present invention further provides a method for producing a fabric product from the above-described material according to the invention. The method for producing the fabric product comprises the inventive method for producing a material of the present invention and includes the steps of: providing a material with thermally fusible fibers and fibers with a higher melting point than the thermally fusible fibers in a predetermined ratio thereof, and heating a predetermined area of ​​the material to increase the degree of thermal fusion of that area compared to other areas.

[0015] The process for manufacturing a fabric product further comprises the following steps: forming a fabric product from the material by cutting, sewing, folding, or combining it into a semi-product (semi-product manufacturing step) and heating a predetermined area of ​​the semi-product (thermal melting step). The process may include a thermal melting step in which a predetermined area of ​​the material produced in the preparation step is heated, and a final process in which a fabric product is formed from the material after the thermal melting step by cutting, sewing, folding, or combining it.

[0016] The material or material product according to the invention, with the configuration described above, allows different designs to be realized with a smaller number of parts, and the product design is expanded. Effect of the invention

[0017] The present disclosure and invention make it possible to obtain materials with different properties, e.g., strength, hardness, texture, and the like, depending on the region. This allows for the production of various types of fabric products.

[0018] Examples of the present disclosure and invention are described in detail below with reference to the drawings. It should be noted that the dimensions, ratios, or numbers may be exaggerated or simplified where necessary to facilitate understanding, since the drawings serve to conceptually illustrate the present invention, and the present invention is not limited to them. 1. Material used in embodiments of the present invention.

[0019] First, the material 1 used in the embodiment of the present invention is described. Although a knitted fabric is described as an example of the material 1, a woven fabric or a nonwoven fabric can be used as the material 1; that is, the present invention can be applied to materials including woven fabrics and textiles in general.

[0020] For example, substance 1 includes, as in Fig. Figure 2 shows a predetermined ratio of thermally meltable fibers (thermally meltable yarns) 3 and other fibers (other yarns) 5 with a higher melting point than the thermally meltable fibers 3. The mixing ratio of the thermally meltable fibers 3 and the other fibers 5 will be described later. First, the structure and composition of the thermally meltable fiber 3 will be described. As shown in Fig. As shown in Figure 1(A), the thermally fusible fiber 3 is a composite filament with a core-sheath structure consisting of a core section 3A and a sheath section 3B. The sheath section 3B consists of a resin with a lower melting point than that of the core section 3A and covers the outer circumference of the core section 3A.

[0021] When the sheath 3B is cooled after fusion or melting by heating, the thermally fusible fibers 3 adhere to each other or to other fibers to be joined (fixed), as in Fig. 1(B) is shown. Through such thermal fusion, the thermally meltable fiber 3 can retain its strength even after fusion.

[0022] To function as a thermally fusible fiber 3, the sheath 3B preferably has a melting point that is 20°C or more, and preferably 30°C or more, lower than the melting point of the core 3A. That is, the melting point of the sheath 3B is lower than the melting point of the core 3A by at least 20°C and preferably by at least 30°C.

[0023] Since the thermally meltable fiber 3 of the embodiment of the present invention has a core-sheath structure, it is generally produced by a melt spinning process. The core component, which forms the core section 3A, is polyester, and the sheath component, which forms the sheath section 3B, is a low-melting-point polyester.

[0024] Therefore, the polyester as the core component is not particularly limited, as long as the effect of the present invention is not impaired, and can have a composition that does not impair the functionality of melt spinning with the sheath component, and can, for example, be a homopolyester or a copolymerized polyester. The melting point of the core component can be 210°C or higher, and preferably 220°C or higher, if, for example, the melting point of the low-melting polyester is 190°C. Other types of polyester or resins other than polyester can be used as the material of the core 3A.

[0025] If the core component is a copolymerized polyester, to improve the strength of the thermally meltable monofilament, it is preferable that its limiting viscosity lies in the high viscosity range of 0.66 to 0.90, particularly in the high viscosity range of 0.68 to 0.85. Among these, it is best to use high-viscosity PET (polyethylene terephthalate) with a limiting viscosity of 0.68 to 0.85.

[0026] The low-melting-point polyester, which is a shell component forming sheath 3B, is not particularly limited as long as it does not impair the effects of the present invention and may have a lower melting point than the polyester of the core component of the present invention by 20°C or more, preferably 30°C or more. For example, copolymerized polyesters obtained by copolymerization of isophthalic acid, adipic acid, 1,4-butanediol, and the like may be mentioned. Among them, polyester obtained by copolymerization of isophthalic acid is preferable, and PET obtained by copolymerization of isophthalic acid is particularly preferable. When using isophthalic acid-copolymerized PET, it is preferable, with regard to spinnability and cost, to copolymerize 20 to 40 mol% of the shell component.

[0027] Suitable combinations of the core and sheath components include a combination of homo-PET and isophthalic-copolymerized PET, a combination of high-viscosity copolymerized PET and isophthalic-copolymerized PET, and similar combinations. Among these, the combination of high-viscosity copolymerized PET and isophthalic-copolymerized PET is more suitable, as it ensures sufficient fiber or yarn strength. Other types of polyester or resins besides polyester can be used as the sheath material (3B).

[0028] In one embodiment of the present invention, the melting point of the sheath component, a low-melting-point polyester, is 190°C. By heat-treating the thermally fusible fibers 3, the low-melting-point polyester forming the sheath 3B is fused or melted, for example to form a monofilament (single yarn) from a multifilament, as in Fig. 1(B) is shown.

[0029] The fineness of the thermally meltable fiber 3 with such a composition can be selected according to the desired properties such as strength, hardness, and texture of a fabric or fabric product, and can, for example, range from 20 to 300 dT (decitex). Furthermore, it is preferable that the thermal shrinkage of the thermally meltable fiber 3 be 10% or less, so that the fabric or fabric product does not shrink excessively or distort when the heat-setting process is carried out by a heating method such as hot pressing.

[0030] As a specific example of the above-mentioned thermally meltable fiber 3, a low-melting-point filament is available under the trade name “Bellcouple” (registered trademark) from KB Seiren Co. Ltd.

[0031] Next, another fiber (another yarn) 5 is described, which is blended into the fabric 1. The other fiber 5 consists of a resin, such as polyester. In the present embodiment, the polyester used as the other fiber 5 has a higher melting point than the melting point of the low-melting-point polyester that forms the sheath component 3B of the thermally fusible fiber 3. The polyesters of the other fibers 5 can be the same as the core components 3A of the aforementioned thermally fusible fibers 3.

[0032] Furthermore, the fineness of the polyester forming the other fiber 5 can, for example, be in the range of 20 to 300 dT (decitex), and the melting point of the polyester forming the other fiber 5 is, for example, 210°C or more, preferably 220°C or more, and preferably 225°C or more. However, the other fibers of the present invention are not limited to the polyester with the aforementioned composition, fineness, and melting point, as long as they have a melting point higher than that of the aforementioned low-melting-point polyester. The other fibers can be one type of fiber or a plurality of fiber types.

[0033] In material 1 according to the embodiment of the present invention, it is preferable, for example in the knitted fabric, as in Fig. As shown, the thermally fusible fibers (thermally fusible yarns) 3 are knitted uniformly when considered in relation to the fabric piece per unit area. That is, one of several rows per unit area is a thermally fusible fiber (thermally fusible yarn). Furthermore, it is preferable that the thermally fusible yarn 3 is woven uniformly in the fabric as warp and / or weft yarn. That is, one of several is a thermally fusible yarn per unit area.

[0034] The ratio of the thermally fusible fibers 3 to the other fibers 5 in the fabric 1 can be appropriately adjusted according to the properties, such as thickness, strength, hardness, etc., required for the fabric product to which the fabric 1 is applied. For example, in one embodiment of the present invention, considering that the fabric 1 is applied to the clothing 10 and the bag 20, the ratio of the number of thermally fusible fibers 3 to the number of other fibers 5 is essentially 1:1. If the fabric 1 is a knitted fabric, the single-loop configuration is knitted with thermally fusible fibers 3 and other fibers 5. If the ratio of the thermally fusible fibers 3 to the other fibers 5 is expressed as a weight, approximately 40 to 80 wt.% of the fabric 1 is the thermally fusible fibers 3 and the remainder is other fibers 5 (a total of 100 wt.%).However, the present invention is not limited to this relationship.

[0035] When the low-melting-point polyester, which is a sheath component of the thermally fusible yarn 3, is worked into or folded into the fabric 1, the low-melting-point polyester begins to melt or thermally fuse at a temperature lower than the target melting point of the thermally fusible yarn 3. The inventors have found that, in the case of the thermally fusible yarn 3 with a melting point of, for example, 190°C, the sheath 3B begins to melt or fuse at 120°C to 130°C, and melting or fusion is accelerated at a heat treatment temperature above 150°C.

[0036] Fabric 1 containing the thermally fusible yarn 3 in a proportion of approximately 50 to 70 wt.% as in the embodiment of the present invention is not as hard, but fabric 1 containing the thermally fusible yarn 3 in a proportion of 100 wt.% hardens remarkably after the dyeing and drying steps. Regardless of the ratio of the thermally fusible yarns 3, at a heating temperature of 190°C the sheath 3B is almost completely melted or molten, and fabric 1 attains its hardest desired state.

[0037] Therefore, in one embodiment of the present invention, the properties of the thermally fusible yarn 3 described above are used to cure or harden certain areas of the fabric 1 more than other areas. In other words, the fabric 1, which contains the thermally fusible fibers 3 in a predetermined ratio, is prepared, and the heat treatment is carried out on a predetermined area (second area) of the fabric 1, thereby increasing the degree of fusion of the sheath section 3B more than other areas (first area). The fabric 1 thus produced consequently has an area (first area) in which the degree of fusion of the sheath 3B is relatively low and an area (second area) in which the degree of fusion of the sheath 3B is relatively high.

[0038] Here, the heating method can be modified depending on the required degree of hardening or curing, the thickness of the fabric 1, the type of intended fabric product, and the like. For example, if the clothing 10 is manufactured as in embodiment 1 described later, the fabric 1 can be heat-pressed while partially covered with a thick felt. Using this method, the exposed part of the fabric 1 can be cured by heat, while the curing of the remaining part can be inhibited. Since simple tools can be prepared for this method, the acquisition costs are low, and it is suitable for a wide variety of products and for small-batch production.

[0039] Furthermore, in the manufacture of the bag 20, as in embodiment 2 described later, it is also possible to harden only a desired area by folding and pressing the fabric 1 while the desired area is positioned on the front. This method also requires no additional pressing equipment and can be easily prepared, resulting in low acquisition costs and making it suitable for a variety of products and small-batch production. It should be noted that each of the heating processes described above can be carried out individually or in combination.

[0040] When a jersey fabric (knit) including the thermally meltable yarn 3 is heated as described above, the heated section exhibits a structure similar to a woven fabric. Consequently, within the individual fabric 1, there is an area (unheat-treated area) with the suppleness or flexibility of a jersey fabric and an area (heat-treated area) with a stable shape, thus expanding the usability of the fabric 1.

[0041] Incidentally, the fabric can undergo a dyeing step before heat treatment, and the dyeing step is carried out, for example, as follows. As a pretreatment, it is preferable to wash the fabric with water or a surfactant to remove oil and dirt.

[0042] In the dyeing step, a method for passing the fabric through a dye bath can be used, and various dyeing machines such as a Wins dyeing machine and a liquid stream dyeing machine can be used as dyeing machines.

[0043] Various dyes can be used for coloring; their types are not particularly limited, but a disperse dye is preferable with regard to the dyeability of polyester fibers. For example, an azo or anthraquinone dye can be used as a disperse dye.

[0044] When using a disperse dye, an equalizing agent, a dispersing agent, and a pH adjuster can be added to the dye bath, either individually or in combination. For example, a non-ionic equalizing agent (such as an alkylphenol-oxidized ethylene additive) or a specific anionic equalizing agent (such as an ether-type non-ionic sulfuric acid ester) can be used. For example, an anionic dispersing agent (such as a formalin condensation product of sodium aromatic sulfonate) can be used.

[0045] The dye bath is then heated under high pressure to approximately 130°C, and the fabric is immersed in the dye bath at approximately 130°C for about 30 minutes. Afterwards, a reduction wash is performed as a post-treatment to remove unfixed dyes and impurities adhering to the fabric, and then the fabric is dried. Drying can be achieved, for example, by storing the fabric in an atmosphere at approximately 160°C.

[0046] It is preferable that each step of the process for producing a substance or a substance product of the present invention satisfies the following relational expressions (1) and (2) with respect to the temperature conditions. T1 <T3<T5 T2 <T3<T5 where T1 is the dyeing temperature of the fabric, T2 is the drying temperature of the fabric, T3 is the melting point of the thermally fusible fiber 3 forming the fabric, T5 is the melting point of the other fibers 5 forming the fabric, and the units of T1, T2, T3 and T5 are °C.

[0047] By manufacturing a fabric or fabric product in a single step that meets the above-mentioned temperature conditions, a core material is not required separately to form a frame as a fabric product, thus expanding the range of product design.

[0048] Below, a garment and a bag are given as examples of fabric products made with fabric 1. However, the fabric according to the present invention is not limited to clothing and bags, but can be applied to all fabric products in general. 2. Design 1

[0049] A garment 10 according to embodiment 1 of the present invention is described. Here, a sleeveless shirt, as shown in [reference to garment 10], is given as an example of the garment 10. Fig. The invention is used as shown. However, the present invention also applies to other types of clothing, such as jackets, one-piece clothing, underwear, trousers, etc.

[0050] The clothing 10 according to the first embodiment comprises a front body 11 and a back body 13, as shown in Fig. Figure 3 shows the garment 10. It has a collar 15 and may also include parts such as buttons and pockets. In the garment 10, at least the front body 11 and the back body 13 are made of fabric 1; such a garment 10 can be produced by the following step.

[0051] In embodiment 1, knitted fabrics containing 40 to 60 wt.% thermally meltable yarn 3 are used as materials 1 for the front body 11 and the rear body 13 according to Fig. 4 (A) and (B) are used. The other yarn 5, with the exception of the thermally meltable yarn 3, is, for example, a polyester fiber, such as polyethylene terephthalate. The other yarn 5 may, for example, have 84 Decitex-48 filaments, 56 Decitex-36 filaments, 56 Decitex-36 filaments, 84 Decitex-36 filaments, 100 Decitex-48 filaments, or 56 Decitex-48 filaments and may have a melting point of, for example, 225°C. The other yarn 5 may be a crimped yarn.

[0052] For example, jersey knitting is used as the knitting method for fabric 1, and in particular a single Denbigh stitch (warp-knitted fabric) is used, as in Fig. As shown, in the single Denbigh stitch, the thermally fusible yarn 3 is used to form a section called a Denbigh, and there is one Denbigh per unit area. Thus, this type of fabric is thinner and lighter compared to the double Denbigh knit described in embodiment 2.

[0053] After the aforementioned fabric 1 has been prepared, the fabric 1 is cut and the front body 11 and the back body 13 are cut according to Fig. and (B) are being prepared. In Fig. 4 (A) and (B) the dashed line indicates a fold line and the dashed line indicates a seam.

[0054] Then, as in the Fig. 5 (A) and (B) shown, section 15A and 15B corresponding to collar 15 in Fig. To expose the front body 11 and the back body 13, the front body is masked with thick felt F. The masking is done to prevent the body from hardening and becoming brittle during the heat treatment process. At this point, a predetermined section other than the collar section 15, such as a side body section (a boundary section between the front and back body), a yoke, a pocket, a skirt, a front foot, a front end, a flap, a belt, a belt loop, or the like, can be hardened. In this case, the masking can be carried out in such a way that the predetermined section is also exposed.

[0055] Then the front body 11 and the back body 13, which is covered with felt F, are heat-pressed to harden sections 15A and 15B, which correspond to the collar 15. Afterwards, parts such as trim, buttons, pockets, and the like are sewn on as necessary, and the front body 11 and the back body 13 are sewn together to form the garment 10 as shown. Fig. 3 shown to complete. 3. Design 2

[0056] The bag 20 according to the second embodiment of the present invention is then described. Here, a carrier bag, as in Fig. The bag 20 is shown as an example, but the present invention also applies to other types of bags, such as a backpack.

[0057] The bag 20 according to the second embodiment includes a main body 21 and a handle 23, as shown in Fig. Figure 6 is shown. Bag 20 may also have additional parts, such as inner pockets.

[0058] When used to store an object, the bag 20 can maintain the shape of a container, as in Fig. shown. However, if no object is included, the bag can be 20 as shown. Fig. The bag is shown folded and transported compactly. At least the main body 21 of the bag 20 consists of fabric 1, which can be produced by the following step.

[0059] In the second embodiment, as material 1 for the body of the in Fig. In the bag 20 shown in Figure 6, a knitted fabric is used to which 60% to 80% by weight of the thermally fusible yarn 3 is blended. The other yarn 5, with the exception of the thermally fusible yarn 3, consists, for example, of a polyester fiber, such as polyethylene terephthalate. The other yarn 5 can, for example, have 84 Decitex-48 filaments, 56 Decitex-36 filaments, 56 Decitex-36 filaments, 84 Decitex-36 filaments, 100 Decitex-48 filaments, or 56 Decitex-48 filaments and can have a melting point of, for example, 225°C. The other yarn 5 can be a crimped yarn.

[0060] Furthermore, jersey knitting is used as the knitting method for fabric 1, and in particular a double Denbigh stitch is used. In the double Denbigh stitch, the thermally fusible yarn 3 is used for the Denbigh stitch, and this Denbigh stitch is twice as large as the single Denbigh stitch. Thus, this type of fabric finish is thicker (heavier) than the single Denbigh stitch fabric described in embodiment 1.

[0061] The fabric 1 described above is prepared for the main body 21 of the bag 20, and the fabric 1 is cut into an essentially rectangular shape, as shown in Fig. 8 shown here Fig. 8. A dashed line indicates a fold line and a dashed line indicates a seam. At the same time, parts such as a handle 23, a belt 25, a lining (not shown) and a pocket (not shown) are prepared.

[0062] Next, as in Fig. Figure 9 shows sections 27A and 27B, corresponding to the muzzle section 27 of the main body 21, exposed, and the other sections covered with felt F. This is a masking to prevent the section of the main body 21 that is not the muzzle section 27 from hardening and curing due to heating.

[0063] The portion of fabric 1 covered with felt F is then heat-pressed, and parts 27A and 27B corresponding to the muzzle section 27 are cured. Additionally, the base fabric (not shown) and the handle 23 can be cured by heating. At this point, the press can be set to maintain a temperature of, for example, 185°C on one side for 60 seconds. The pressure of the press can be adjusted according to the desired degree of curing.

[0064] The main body 21 is then ironed with an iron or similar along the dotted line in Fig. pressed into pleats. Then other parts, such as a lower fabric and pockets, are sewn to the main body 21, and both sides and the bottom of the main body 21 are sewn. Then, as in Fig. Figure 10 shows the outer surface 21A formed on the main body 21.

[0065] The outer surface 21A of the main body 21 is then heat-pressed on both sides to harden it. Since the part not to be hardened was positioned inside in the previous folding step, it is simply heat-pressed without using the felt F. The press can be set to a temperature of, for example, 185°C for 60 seconds. During the heat-pressing process, it is preferable to place thick paper between the press and the main body 21 to eliminate any unevenness in the press caused by a difference in thickness relative to a part of the main body 21.

[0066] After heating by the press, parts such as the handle 23 and the strap 25 are attached to the main body 21, thus completing the bag 20.

[0067] Although representative embodiments of the present invention have been described above, the present invention is not limited to these, and various design changes are possible, and all such design changes are included in the technical scope of the present invention.

[0068] Another heating method involves preparing a mold with a form corresponding to the section to be heated (a form shaped like a heating surface) and pressing the form onto the section to be heated. However, this method is not suitable for mass production because manufacturing a mold die incurs significant costs. This method can be used alone or in combination with the pressing process using masked fabric 1 and / or the pressing process using folded fabric 1.

[0069] Furthermore, in the embodiment of the present invention, low-melting-point polyester is used as the sheath component of the thermally meltable fiber 3, but it is also possible to use a thermally meltable fiber with low-melting-point polyester as the core component. That is, it is possible to produce a fabric using a thermally meltable fiber in which the melting point of the sheath section is higher than the melting point of the core section by a predetermined temperature (e.g., 20°C) or more, and to produce a fabric product (clothing, bag, etc.) including the fabric.

[0070] In the embodiment of the present invention, polyester fibers are used as other fibers (other yarns) 5, but chemical fibers (e.g., nylon fibers) that are neither polyester fibers nor natural fibers can also be used. The other fibers (other yarns) 5 can be thermally meltable fibers with a higher melting point than the thermally meltable fibers 3 or thermally meltable fibers with a lower melting point.
