Description

[[Technical Field]]

[0001] The present invention relates to a fabric edge adhesive treatment structure for fabrics such as clothing. [[Background Art]]

[0002] Due to the improvement of technologies related to fabrics, there is no fraying at the edges, and the use of so-called cut-edge fabrics with the fabric edges left in an unprocessed state is increasing. This is because eliminating sewing on all or part of the garment improves wearing comfort. Adhesives are sometimes used when folding back the edges of garments made from such cut-edge fabrics.

[0003] A technique for bonding such edge adhesive treatment using dot-shaped adhesives arranged in a single row or multiple rows is disclosed (for example, Patent Document 1). This technique suppresses the reduction of adhesive force by adjusting the spacing of the adhesive between the maximum and minimum curvature radius portions of the opening.

[0004] The prior art disclosed in Patent Document 1 is effective in suppressing the reduction of adhesive force mainly in a single row or multiple rows (two rows), but it changes the spacing of the adhesive according to the radius of curvature, resulting in a complicated structure and cannot be realized with a simple configuration.

[0005] [[Patent Document 1]] Japanese Patent No. 6916844 [[Summary of the Invention]] [[Problem to be Solved by the Invention]]

[0006] In view of the above problem, an object of the present invention is to provide a garment using a fabric edge adhesive treatment structure that suppresses reduction of adhesive force and can be realized with a simple configuration. [[Means for Solving the Problem]]

[0007] To solve the above problems, the garment using the fabric edge bonding structure according to the present invention is a garment using a fabric edge bonding structure that bonds the edges of a stretchable fabric, A fold line that forms a folded-over piece at the edge of the aforementioned fabric, The folded portion has an adhesive section consisting of three or more rows in a parallel direction, with adhesive continuously applied in a dot pattern at equal intervals in the direction of arrangement. A garment using a fabric edge bonding treatment structure characterized by folding the folded portion along the aforementioned folding line to form the fabric edge.

[0008] Furthermore, it is preferable to form the fabric edge bonding structure at the opening of the garment and to arrange the bonding portion across the entire opening.

[0009] Furthermore, the dot-shaped adhesive portion consisting of three or more rows in a parallel direction comprises a fabric edge side row located closest to the fabric edge on the folded piece, a folded line side row on the folded line side, and one or more intermediate rows located between the fabric edge side row and the folded line side row. A line passing through the center positions of the dots in the fabric edge side row and the dots in the fold line side row is defined as the first reference line, and the center positions of the dots in the intermediate row are offset from the first reference line to form a misaligned arrangement. It is preferable to perform the aforementioned misaligned arrangement on at least a portion of the garment fabric edge bonding structure.

[0010] Furthermore, for the offset arrangement, it is preferable to use a line passing through one end in the direction of arrangement of the dots in the fabric edge side row and the dots in the fold line side row as a second reference line, and for the other end in the direction of arrangement of the dots in the intermediate row to be offset in the direction of arrangement from the second reference line.

[0011] Furthermore, in the offset arrangement, it is preferable that the center position of the dots in the intermediate column is the center position of the first reference line 1 and the other adjacent first reference line.

[0012] Furthermore, a dot-shaped adhesive section consisting of three rows in a parallel direction is defined as a unit adhesive section, and multiple unit adhesive sections consisting of two or more units are arranged in a parallel direction. In the offset arrangement, for each unit bonding section, it is preferable that the center position of the dots in the intermediate row is offset from the first reference line, with a line passing through the center positions of the dots in the fabric edge side row and the dots in the fold line side row being used as the first reference line. [Effects of the Invention]

[0013] According to the invention described in claim 1, it is possible to provide clothing using a fabric edge bonding treatment structure that suppresses a decrease in adhesive strength and can be realized with a simple configuration. That is, by forming the adhesive in a dot shape over three or more rows, it is possible to improve the adhesive strength and provide clothing that suppresses a decrease in adhesive strength with a simple configuration.

[0014] According to the invention described in claim 2, it is possible to provide clothing in which an opening is formed in the clothing and three or more rows of adhesive portions are arranged continuously throughout the entire opening, thereby suppressing a decrease in adhesive strength.

[0015] According to the invention described in claim 3, because the dots in the intermediate row are misaligned from the reference line of the dots consisting of the fabric edge side row and the fold line side row, the non-adhesive areas between the dots in the dot-shaped adhesive area cause a decrease in adhesive strength. Therefore, by arranging the intermediate row in a position along these non-adhesive areas while having a predetermined elasticity, it is possible to improve the adhesive strength with a simple configuration.

[0016] According to the invention described in claim 4, it is possible to improve the adhesive strength of the non-adhesive portions between the dots in the fabric edge side row and the fold line side row with a simple configuration. That is, since the dot adhesion of the intermediate row is located entirely in the non-adhesive portion, it is possible to improve the adhesive strength with a simple configuration.

[0017] According to the invention of claim 5, the dots in the intermediate row are positioned between two first reference lines in a so-called staggered arrangement, which makes it possible to efficiently suppress a decrease in adhesive force at the non-bonded portions between the dots.

[0018] According to the invention of claim 6, by arranging a plurality of three-row adhesive portions as unit adhesive portions in the parallel direction and performing misalignment arrangement for each unit adhesive portion, while providing predetermined stretchability, the intermediate row is arranged at a position along the non-bonded portion. This not only contributes to improvement of adhesive force with a simple configuration, but also makes it possible to further improve adhesive strength. BRIEF DESCRIPTION OF THE DRAWINGS

[Modes for carrying out the invention]

[0020] Embodiments of the adhesive portion 20 in the fabric edge bonding structure of garment 1 of the present invention will be described based on the drawings. The embodiments described below are provided to facilitate understanding of the invention and are not intended to limit the invention. In this description, the parts of each drawing are referred to as "top," "bottom," "left," "right," "front," and "back."

[0021] In this embodiment, garment 1 is primarily intended as underwear, and Figure 1 shows a tank top-type innerwear as an example. However, garment 1 is not limited to Figure 1 and may be shorts or a camisole, or other clothing such as a T-shirt in addition to underwear.

[0022] As shown in Figure 1, the garment 1 has openings 2. There are openings 2 that form the collar 2a, openings 2 that form the armhole 2b, and openings 2 that form the hem 2c. The fabric edge bonding structure may be provided for all openings 2, 2, but in this embodiment, the fabric edge bonding structure is applied to the openings 2 that form the collar 2a and the openings 2 that form the armhole 2b, and is not applied to the opening 2 that forms the hem 2c, where it is sewn rather than glued.

[0023] Furthermore, as described later, the adhesive portion 20 at the opening 2 is folded back to the inside (skin side) of the garment 1 by the fold line 12, and in Figure 1, only the adhesive portion 20 formed on the back of the collar 2a is exposed.

[0024] The fabric used in this embodiment is a stretchable fabric, and is a so-called raw-edge material that is cut and has raw edges. Specifically, the raw-edge material fabric used is a rib knit fabric, but it is not limited to this fabric, and bare rib knit fabric or other fabrics may also be used.

[0025] The adhesive portion 20 in the fabric edge bonding structure will now be described. As shown in Figures 2(a) and (b), in this embodiment, the edge of the fabric at the opening 2 is folded back and bonded with adhesive. Specifically, a fold line 12 is formed from the fabric edge 11, leaving a predetermined width, and the area from this fold line 12 to the fabric edge 11 is made into a folded piece 13. Note that forming the fold line 12 does not mean actually drawing a line, but rather recognizing the fold line in advance and folding it after the adhesive portion 20 is formed.

[0026] The adhesive portion 20 of the fabric edge bonding structure will now be described. As shown in Figure 3, the adhesive portion 20 of this embodiment consists of a coating arrangement in which adhesive is applied in three rows of dots. In other words, the coating arrangement means that continuous dot-shaped adhesive is applied to the folded piece 13 of the opening 2 in the longitudinal direction (arrangement direction) to form a predetermined shape, and that such dot-shaped coating arrangements are formed in three rows in the arrangement direction with predetermined intervals between them. In Figure 3, the left-right direction X on the drawing is called the arrangement direction, and the up-down direction Y is called the parallel direction.

[0027] In this embodiment, each dot is formed in a circular shape, but the embodiment is not limited to this form, and rectangular dots or other shapes may be used. Also, although a polyurethane-based hot melt adhesive is used, the embodiment is not necessarily limited to this, and other adhesives may be used.

[0028] The adhesive portion 20 consists of a folded piece 13 from the fabric edge 11 to the folded line 12, with a fabric edge side row 21 on the fabric edge 11 side, a folded line side row 23 on the folded line 12 side, and an intermediate row 22 located between the fabric edge side row 21 and the folded line side row 23. The dots 21a, 22a, and 23a in each row 21, 22, and 23 are arranged at equal intervals within each row. Note that the spacing between dots is not limited to this embodiment.

[0029] This embodiment describes an adhesive portion 20 consisting of three rows 21, 22, and 23 as an example, but it may also have multiple intermediate rows 22. For example, it may have two intermediate rows 22, resulting in a total of four rows in the adhesive portion 20, or it may have three intermediate rows, resulting in a total of five rows in the adhesive portion 20, or other configurations (see Figures 7(a) and (b)).

[0030] In this embodiment, the spacing between each row of fabric edge side row 21, intermediate row 22, and fold line side row 23 is equal. However, as shown in Figure 7(a), the spacing between multiple intermediate rows 22, 22 may be narrowed, or, although not shown, the spacing between each row of fabric edge side row 21, intermediate row 22, and fold line side row 23 may be different.

[0031] In the three-row standard dot arrangement shown in Figure 3, the dots 21a, 22a, and 23a of each parallel fabric edge-side row to fold-over-line row 21, 22, and 23 are located in the same position. This is because, when the line passing through the center positions of the dot 21a of the fabric edge-side row 21 and the dot 23a of the fold-over-line row 23 is defined as the first reference line S1, the center position of the dot 22a of the intermediate row 22 is also located along this first reference line S1. By using this dot arrangement, it is possible to improve adhesive strength with a simple configuration while maintaining elasticity.

[0032] Next, the misaligned arrangement of the adhesive portion 20 will be described. This embodiment includes a first misaligned arrangement, a second misaligned arrangement, and a third misaligned arrangement, as described below. As shown in Figure 4, the first misaligned arrangement is one in which the dot 22a of the intermediate row 22 is misaligned so that it partially overlaps the first reference line S1 in the direction of arrangement from the dots 21a, 22a, and 23a of each row 21, 22, and 23 which are in the parallel direction.

[0033] Specifically, when the line passing through the center positions of the dots 21a in the fabric edge row 21 and the dots 23a in the fold line row 23 is defined as the first reference line S1, the center position of the dots 22a in the intermediate row 22 is shifted in the direction of arrangement from the first reference line S1. In other words, the dots 22a in the intermediate row 22 are positioned so as to partially overlap the dots 21a and 23a in the fabric edge row 21 and the fold line row 23 in the direction of arrangement.

[0034] By performing this first misaligned arrangement, it becomes possible to maintain constant elasticity while improving the adhesive strength of the non-adhesive portion between the dots of the fabric edge side row 21 and the fold line side row 23 with a simple configuration.

[0035] Next, the second misaligned arrangement of the adhesive portion 20 will be described. As shown in Figure 5, the second misaligned arrangement refers to a configuration in which the dots 21a, 22a, and 23a of each of the parallel rows 21, 22, and 23 are misaligned from the second reference line S2 such that the dot 22a of the intermediate row 22 does not overlap in the direction of arrangement.

[0036] Specifically, when the line passing through one end of the dot 21a in the fabric edge row 21 and the dot 23a in the fold line row 23 in the direction of arrangement is defined as the second reference line S2, the other end of the dot 22a in the intermediate row 22 is offset in the direction of arrangement from the second reference line S2. In other words, the dot 22a in the intermediate row 22 is positioned so that it does not overlap with the dots 21a and 23a in the fabric edge row 21 and the fold line row 23 in the direction of arrangement.

[0037] By performing this second misaligned arrangement, it becomes possible to improve the adhesive strength of the non-adhesive portion between the dots of the fabric edge side row 21 and the fold line side row 23 with a simple configuration.

[0038] Next, the third misaligned arrangement of the adhesive portion 20 will be described. As shown in Figure 6, the third misaligned arrangement is such that the dot 22a of the middle column 22 is misaligned from the first reference line S1 so that it does not overlap in the direction of arrangement among the dots 21a, 22a, and 23a of each row 21, 22, and 23 which are in the parallel direction, and is positioned in a staggered pattern in the center of two adjacent first reference lines S1, S1.

[0039] Specifically, the line passing through the center positions of the dots 21a in the fabric edge side row 21 and the dots 23a in the fold line side row 23 is defined as the first reference line S1, and other adjacent first reference lines S1 in the direction of arrangement are defined as such. The intermediate row 22 is shifted in the direction of arrangement such that the center position of the dots 22a in the intermediate row 22 lies at the center position of one first reference line S1 and another adjacent first reference line S1. In other words, the dots 22a of the intermediate row 22 are positioned midway between the dots 21a in the fabric edge side row 21 and the dots 23a in the fold line side row 23, extending in the direction of arrangement.

[0040] By performing this third positional misalignment, it becomes possible to dramatically improve the adhesive strength of the non-adhesive portion between the dots of the fabric edge side row 21 and the fold line side row 23 with a simple configuration.

[0041] Furthermore, as shown in Figure 8, it is also possible to treat a three-row adhesive section 20 as one unit adhesive section, and to perform offset placement of dots 21a, 22a, and 23a in two unit adhesive sections (multiple unit adhesive sections) 20a and 20b. A unit adhesive section 20a and 20b consists of three rows, each containing a fabric edge side row 21 on the fabric edge 11 side, a fold line side row 23 on the fold line 12 side, and an intermediate row 22 between the fabric edge side row 21 and the fold line side row 23, and multiple such three-row unit adhesive sections 20a and 20b are arranged in parallel.

[0042] By arranging multiple adhesive sections 20 consisting of three rows as unit adhesive sections 20a and 20b in a parallel direction, and by offsetting the position of each unit adhesive section 20a and 20b, it is possible to not only improve the adhesive strength with a simple configuration, but also to further improve the adhesive strength by positioning the intermediate row along the non-adhesive portion while maintaining a predetermined elasticity.

[0043] The embodiment shown in Figure 8 involves a first misaligned arrangement in the two unit adhesive sections 20a and 20b, but a second misaligned arrangement and a third misaligned arrangement may also be performed. Alternatively, a normal dot arrangement may be used, in which case it will be the same as the 6-row arrangement in the embodiment shown in Figure 7.

[0044] The above-mentioned normal dot arrangement, first offset arrangement, second offset arrangement, and third offset arrangement may be appropriately arranged considering the strength and elasticity of the opening 2. For example, the armhole 2b may be arranged in the normal dot arrangement, while the collar 2a may be arranged in one of the first, second, or third offset arrangements, or a combination of the normal dot arrangement and the offset arrangement may be used in one opening 2.

[0045] Furthermore, regardless of whether the arrangement is a normal dot arrangement, a first misaligned arrangement, a second misaligned arrangement, or a third misaligned arrangement, it is preferable to arrange the adhesive portion consisting of three rows across the entire opening 2. By arranging it in this way, a decrease in adhesive strength at the opening 2 can be suppressed.

[0046] Misaligned placement can be achieved simply by adjusting the spacing between dots when applying adhesive in a dot pattern, making it a relatively easy method to implement. [Explanation of Symbols]
