Description

Technical Field

[0001] The utility model relates to the technical field of clothing manufacturing, and specifically relates to a fabric bonding structure. Background Art

[0002] In the clothing manufacturing industry, most fabrics can be basically divided into freely cuttable fabrics and non-freely cuttable fabrics. Freely cuttable fabrics are high-quality fabrics or cloths that can be freely cut according to the needs of tailors without causing fraying or unraveling. Such fabrics generally have good elasticity and stability, and can all have a high utilization rate due to their freely cuttable characteristics. However, the cost of freely cuttable fabrics is relatively high, and the patterns are limited, so they cannot be widely used.

[0003] Non-freely cuttable fabrics usually refer to those materials that require special attention during the cutting and splicing processes. Because of the physical properties or structural design of the fabric itself, they are not suitable for random cutting, or because the fabric has specific textures and patterns, once the cutting direction is wrong, it may lead to pattern misalignment or texture chaos, affecting the overall aesthetics. However, the quantity of such fabrics accounts for a relatively large proportion in clothing design. The non-freely cuttable characteristic leads to a large amount of leftover materials at the corners and edges, which cannot be effectively utilized. It is difficult to apply different fabrics because of their specific textures and patterns, and the splicing process is not yet perfect. Therefore, non-freely cuttable fabrics have a low utilization rate and waste fabric resources.

[0004] In view of the above deficiencies, we need to develop a fabric bonding structure to meet the usage requirements of the majority of users. Summary of the Utility Model

[0005] In view of the problem that there are a large number of leftover materials at the corners and edges of the existing non-freely cuttable fabrics and they cannot be effectively utilized, and it is difficult to piece together different fabrics, the technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A fabric bonding structure includes a first fabric and a second fabric. The first fabric and the second fabric are adhesively connected through an adhesive layer. The adhesive layer is divided into a first adhesive area and a second adhesive area. The second fabric contacts the front and back sides of the first fabric through the first adhesive area and the second adhesive area respectively.

[0007] Further, the first fabric forms a folding structure through fabric hemming. A folding selvage is formed between the edge c of the first fabric and the fabric hemming. The folding selvage is located between the first fabric and the second fabric.

[0008] Further, the first adhesive area is adhesively bonded to the side of the folding selvage facing the back side, and the second adhesive area is adhesively bonded to the front side and is located close to the folding selvage.

[0009] Further, the first bonding area is located at a position between the edge c and the fabric hem, and the edge c is located between the first bonding area and the second bonding area.

[0010] Further, after being pressed at a position close to the fabric hem, the folding structure forms a crease line.

[0011] Further, the width of the first bonding area is dimension a, the width of the second bonding area is dimension b, and the dimension a is less than the dimension b.

[0012] Further, both the first bonding area and the second bonding area are located on the same side of the second fabric. After the first fabric and the second fabric are bonded, the second bonding area contacts the front side and the first bonding area contacts the back side.

[0013] Further, the bonding layer includes a plurality of bonding points, the bonding points have adhesives, and the plurality of bonding points are arranged at intervals in a straight line along the length direction of the bonding layer. The plurality of bonding points in the second bonding area are arranged at staggered intervals.

[0014] Further, the plurality of bonding points in the first bonding area are arranged in a first linear structure, the plurality of bonding points in the second bonding area are arranged in a second linear structure, and the line width of the first linear structure is greater than the line width of the second linear structure.

[0015] Further, the bonding layer includes at least two bonding sheets respectively located in the first bonding area and the second bonding area. The bonding sheets have adhesives, and the length direction of the bonding sheets is the same as the length direction of the bonding layer.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. The first fabric and the second fabric of the present utility model are adhesively connected through a bonding layer, without the need for binding or using accessories for limiting. The manufacturing process is convenient and fast, and a flat surface can be maintained. The second fabric contacts the front and back sides of the first fabric through the first bonding area and the second bonding area, which can increase the bonding area, strengthen the connection strength, improve the tensile strength of the fabric bonding structure, and improve the bonding stability. For non-free-cutting fabrics connected by this structure, patterns can be randomly spliced while ensuring the connection strength, which is convenient for users to effectively utilize the leftover materials of non-free-cutting fabrics, reduce the splicing difficulty between different fabrics, reduce the backlog of inventory leftovers, and improve the production economic benefits.

[0018] 2. The present utility model further standardizes the bonding point positions of the first bonding area and the second bonding area, enabling the bonding points to facilitate mass production operations and facilitating the positioning of the landing points of the adhesives during glue application. When the second bonding area is bonded to the front side of the first fabric, the position of the second fabric is restricted through the cooperation of the adhesive and the hot pressing process to enhance the bonding effect and bonding stability.

[0025] The following describes in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0026] Optionally, in some embodiments, the first fabric 1 and the second fabric 2 can be made of one of materials such as cloth, leather, knitted fabric, synthetic fiber fabric, etc.

[0027] Optionally, in some embodiments, the bonding layer 3 can be one of adhesives with bonding functions such as glue, adhesive tape, lacquer glue, glue solution, etc.

[0028] Embodiment 1:

[0029] Such as Figures 1 to 5A fabric bonding structure as shown includes at least a first fabric 1 and a second fabric 2. At least two same or different fabrics can be spliced and combined by using the fabric bonding structure. The first fabric 1 and the second fabric 2 are adhesively connected through an adhesive layer 3. The adhesive layer 3 is coated between the first fabric 1 and the second fabric 2 to form a connecting structure with an adhesive effect. The adhesive layer 3 can be divided into a first adhesive area 31 and a second adhesive area 32 according to the adhesive position and range. The first adhesive area 31 and the second adhesive area 32 are adhesively bonded to different positions of the fabric bonding structure. More specifically, when the first adhesive area 31 is adhesively bonded to the front side 11 of the first fabric 1, the second adhesive area 32 is adhesively bonded to the back side 12 of the first fabric 1. On the contrary, when the first adhesive area 31 is adhesively bonded to the back side 12 of the first fabric 1, the second adhesive area 32 is adhesively bonded to the front side 11 of the first fabric 1. Depending on the actual pattern or design of the first fabric 1 and the second fabric 2, or the actual area and shape of the first fabric 1 and the second fabric 2, a suitable splicing position can be selected.

[0030] More specifically, the first fabric 1 forms a folding structure 13 through a fabric hem 21. The fabric hem 21 is the crease boundary when the first fabric 1 is folded. The folding structure 13 is a U-shaped laminated structure formed by the first fabric 1 being folded in half around the fabric hem 21. The folding structure 13 forms a folded edge 131 between the edge c of the first fabric 1 and the fabric hem 21. The folded edge 131 is the fabric area between the fabric hem 21 and the edge c. The width of the folded edge 131 is the distance between the fabric hem 21 and the edge c. The total width of the first fabric 1 is the distance between the edge c and the opposite edge. The width of the folded edge 131 is less than half of the total width of the first fabric 1. After forming the folding structure 13, the folded edge 131 is located between the first fabric 1 and the second fabric 2. On this basis, the side of the folded edge 131 facing the front side 11 is the inner side, and the side of the folded edge 131 facing the back side 12 is the outer side. The first adhesive area 31 is adhesively bonded to the outer side of the folded edge 131 and is located at the position between the edge c and the fabric hem 21. The second adhesive area 32 is adhesively bonded to the position on the front side 11 close to the folded edge 131. After the first fabric 1 and the second fabric 2 are adhesively bonded, the edge c is located at the position between the first adhesive area 31 and the second adhesive area 32.

[0031] After the first fabric 1 and the second fabric 2 are adhesively bonded, it is necessary to pass through a hot pressing process or a cold pressing process to flatten and compact the first fabric 1 and the second fabric 2, so that the adhesive layer 3 is fully bonded, and only then is the bonding structure completed. At this time, a crease line 22 will appear at the position of the fabric hem 21 on the second fabric 2 after pressing. The crease line 22 formed after pressing can also play a role in aesthetics.

[0032] More specifically, the laying width of the first bonding area 31 on the fabric is dimension a, and the laying width of the second bonding area 32 on the fabric is dimension b. The bonding area with the larger width among dimension a and dimension b can be arranged at the position of the front side 11, and the bonding area with the smaller width among dimension a and dimension b can be arranged at the position of the back side 12 to meet the actual aesthetic requirements and the connection stability of the bonding structure.

[0033] More specifically, a number of bonding points 33 are arranged in the first bonding area 31 and the second bonding area 32. The bonding points 33 are bonding positions for placing adhesives. The number of bonding points 33 are arranged at straight-line intervals along the length direction of the bonding layer 3, which can reduce the consumption of adhesives on the basis of ensuring that the bonding path or bonding range is fully covered. During the bonding process, the adhesive will extend a certain range under extrusion. Therefore, each bonding point 33 is independently and spaced apart, which can save the input of adhesives, control the loss of adhesives, avoid excess adhesives being extruded out of the bonding range, and can also obtain the same bonding force, reducing production costs.

[0034] Embodiment 2:

[0035] On the basis of Embodiment 1, the laying width of the first bonding area 31 on the fabric in this embodiment is dimension a, and the laying width of the second bonding area 32 on the fabric is dimension b, satisfying that dimension a is less than dimension b. That is, when the first bonding area 31 and the second bonding area 32 have the same length, the area of the second bonding area 32 is larger than that of the first bonding area 31. At this time, the second bonding area 32 is bonded to the front side 11 of the first fabric 1, and the first bonding area 31 is bonded to the back side 12 of the first fabric 1 to meet the actual aesthetic requirements and the connection stability of the bonding structure.

[0036] More specifically, the number of bonding points 33 in the second bonding area 32 is more than the number of bonding points 33 in the first bonding area 31. The bonding points 33 in the first bonding area 31 are combined along the length direction of the bonding layer 3 to form a single-column linear structure, which is the first linear structure 34. The bonding points 33 in the second bonding area 32 are combined along the length direction of the bonding layer 3 to form a three-column linear structure, which is the second linear structure 35. The linear spaced structure can facilitate the automatic flow addition of adhesives during production. Compared with manual addition of adhesives, it can avoid the chaotic landing points of adhesives, avoid the phenomenon of local density or local vacancy in the bonding range, and effectively ensure the stability of the bonding force.

[0037] Embodiment 3:

[0038] Based on Embodiment 1, different from Embodiment 2, the laying width of the first bonding area 31 on the fabric in this embodiment is dimension a, and the laying width of the second bonding area 32 on the fabric is dimension b, satisfying that dimension a is greater than dimension b. That is, when the first bonding area 31 and the second bonding area 32 have the same length, the area of the first bonding area 31 is larger than that of the second bonding area 32. At this time, the first bonding area 31 is bonded to the front side 11 of the first fabric 1, and the second bonding area 32 is bonded to the back side 12 of the first fabric 1 to meet the actual aesthetic requirements and the connection stability of the bonding structure.

[0039] More specifically, the number of bonding points 33 in the first bonding area 31 is more than that in the second bonding area 32. The bonding points 33 in the second bonding area 32 are combined along the length direction of the bonding layer 3 to form a single-column linear structure, which is the second linear structure 35. The bonding points 33 in the first bonding area 31 are combined along the length direction of the bonding layer 3 to form a three-column linear structure, which is the first linear structure 34. The linear spaced structure can facilitate the automated flow addition of adhesives during production. Compared with manual addition of adhesives, it can avoid the chaotic landing points of adhesives, avoid the phenomenon of local density or local vacancy in the bonding range, and effectively ensure the stability of the bonding force.

[0040] Embodiment 4:

[0041] Different from Embodiments 1-3, in this embodiment, several bonding points 33 are arranged in a continuously connected linear structure. The bonding points 33 in the first bonding area 31 are connected to each other to form a coherent single-column linear bonding path, which is the first linear structure 34. The bonding points 33 in the second bonding area 32 are connected to each other to form a coherent linear bonding path and form a bonding path three times the line width of the first linear structure 34, which is the second linear structure 35. The linear coherent structure can facilitate the automated flow addition of adhesives during production. Compared with manual addition of adhesives, it can avoid the chaotic landing points of adhesives, avoid the phenomenon of local density or local vacancy in the bonding range, and effectively ensure the stability of the bonding force.

[0042] Embodiment 5:

[0043] Different from Example 4, the bonding points 33 located in the second bonding area 32 are connected to each other to form a coherent single column of linear bonding paths, which is the second linear structure 35. The bonding points 33 located in the first bonding area 31 are connected to each other to form a coherent linear bonding path, and a bonding path three times the line width of the second linear structure 35 is formed, which is the first linear structure 34. The use of a linear coherent structure can facilitate the automated flow addition of adhesives during production. Compared with manual addition of adhesives, it can avoid the chaotic landing points of the adhesives, avoid the phenomenon of local density or local vacancy in the bonding range, and effectively ensure the stability of the bonding force.

[0044] Example 6:

[0045] Different from Examples 1-5, the bonding points 33 in the second bonding area 32 of this example can be arranged in a staggered and spaced manner. The staggered and spaced arrangement can further make full use of the layout space of the bonding area and improve the stability and bonding strength of the bonding connection.

[0046] Example 7:

[0047] As Figure 6 shown, different from Examples 1-6, the bonding layer 3 of this example uses a bonding sheet 36 as the bonding medium between the first fabric 1 and the second fabric 2. The bonding sheet 36 is a sheet-like film adhesive. At least two bonding sheets 36 are respectively attached to the first bonding area 31 and the second bonding area 32 on the second fabric 2. The area of the bonding sheet 36 in the second bonding area 32 is larger than the area of the bonding sheet 36 in the first bonding area 31. The bonding sheet 36 adopts a sheet-like film structure, which can facilitate the workers to implement the bonding process. Compared with the bonding points 33 applied by dot coating, the bonding sheet 36 can be directly laid as a whole piece, without the need for multiple spot gluing, simplifying the process difficulty and process time, and having the effect of a more comprehensive bonding area.

[0048] One of the bonding steps of the present utility model is as follows:

[0049] As Figure 1 and Figure 4As shown in the figure, lay the second fabric 2 flat on the tabletop, and apply a plurality of bonding points 33 to form a bonding layer 3 at a position on one side of the edge d of the second fabric 2 close to it. The second fabric 2 is provided with a first bonding area 31 and a second bonding area 32 from the inside to the outside. A position for the fabric hem 21 is reserved between the first bonding area 31 and the second bonding area 32. A part of the bonding points 33 are arranged in the first bonding area 31, and another part of the bonding points 33 are arranged in the second bonding area 32. The bonding points 33 are arranged in a linear structure along the length direction of the edge of the second fabric 2. The number of bonding points 33 in the first bonding area 31 is small, forming a single-column first linear structure 34. The number of bonding points 33 in the second bonding area 32 is large, forming a second linear structure 35 with an interval of three columns. The plurality of bonding points 33 are arranged at intervals with horizontal and vertical displacements.

[0050] As Figure 2 shown, turn the front side 11 of the first fabric 1 upwards, so that the back side 12 covers the first bonding area 31 of the second fabric 2, align the bonding position of the first fabric 1, so that the edge c of the first fabric 1 and the edge d of the second fabric 2 are in an approximately parallel or parallel position. At this time, the second bonding area 32 is located between the edge c of the first fabric 1 and the edge d of the second fabric 2.

[0051] As Figure 2 and Figure 3 shown, turn up the side of the first fabric 1 far from the edge c and turn it over 180 degrees around the edge c towards the edge d, so that the position where the second fabric 2 is provided with the second bonding area 32 is bonded to the front side 11 of the first fabric 1.

[0052] As Figure 5 shown, use a hot pressing process to hot press the first fabric 1 and the second fabric 2 laid flat, so that the adhesives in the bonding layer 3 are accelerated to form a bonding structure and strengthen the bonding strength. After pressing, a crease line 22 is formed at the position of the fabric hem 21 to complete the fabric bonding structure.

[0053] The second bonding step of the present utility model is as follows:

[0054] As Figure 6 shown, different from the first bonding step, the bonding layer 3 is laid with a bonding sheet 36 in the first bonding area 31 and the second bonding area 32, and the first fabric 1 and the second fabric 2 are adhesively connected through the bonding sheet 36.

[0055] The above only further illustrates the technical content of the present utility model with examples, so that it is easier for readers to understand, but it does not mean that the implementation mode of the present utility model is limited to this. Any technical extension or re-creation based on the present utility model is protected by the present utility model. The protection scope of the present utility model is subject to the claims.
