Description

Technical Field

[0001] The present application relates to the technical field of manufacturing filled down jackets, and in particular to a sealing sewing method for down jackets. Background Art

[0002] In the prior art, when the home textile sewing processing industry manufactures a down jacket or other product filled with down or feathers, it is necessary to sew several horizontal and vertical cross-direction support and separation cloths on the inner side of the upper and lower fabrics of the product, sew the respective support and separation cloths on the inner side of the upper and lower fabrics along the designed sewing lines, and sew the horizontal and vertical cross-direction support and separation cloths on the inner side of the upper and lower fabrics to form several vertical lining-type inner filling chambers. Due to the action of the machine needle and the sewing thread during the sewing process, pinholes are left at the position of the sewing thread. Therefore, during the production process and the use of the finished product, the filling down or feathers in the inner filling chamber will leak out from the pinholes. Therefore, in the prior art, the use of multiple layers of fabrics can be sewn with fine needles and fine coins to reduce the leakage of down. However, since the pinholes are not closed, the barrier down or feathers will still leak out from the pinholes. If the fabric is sewn multiple times to reduce the down running, it is also easy to form sewing lines on the surface of the fabric, affecting the appearance of the down jacket.

[0003] The prior art also adopts a method of pre-coating glue and hot stamping on the inner side of the two layers of fabric along the designed sewing line, and the width of the glue and hot stamping area is greater than the width of the preset sewing line, and then sewing is performed in the area after gluing along the preset sewing line. This process can only be applied to products that are not made by the inner lining process. For example, the pinholes in the sewing part of the product made by the process technology of sewing the inner lining process still have direct contact with the filling down or feathers, resulting in leakage of down. Summary of the invention

[0004] In order to solve the above problems in the prior art, namely to provide a down jacket with beautiful and neat appearance and not prone to down loss, the present invention provides a sewing method for down jacket products.

The subsequent description of the specification is a preferred embodiment of the present invention, but the description is based on the general principles of the specification and is not intended to limit the scope of the present invention. The scope of protection of the present invention shall be determined by the attached claims.

[0028] refer to Figure 1 The present application provides a sealing sewing method for a down jacket, characterized in that: the down jacket comprises a first liner material 2 and a second liner material 9 arranged opposite to each other, a first supporting and separating cloth 4 is arranged on the first liner material 2; and a second supporting and separating cloth 11 is arranged on the second liner material 9;

[0029] The first supporting partition cloth 4 and the second supporting partition cloth 11 are arranged between the first bile material 2 and the second bile material 9, and the first supporting partition cloth 4 and the second supporting partition cloth 11 can overlap and correspond to each other in the same direction, so that the first supporting partition cloth 4 and the second supporting partition cloth 11 can be propped up between the first bile material 2 and the second bile material 9, so that there is enough space between the first bile material 2 and the second bile material 9 to fill the filler, thereby improving the comfort of the down jacket.

[0030] S1, marking a preset overlap line on the first liner material 2 and the first supporting separator 4, and overlapping the first liner material 2 and the first supporting separator 4 along the preset overlap line in sequence to form a first sewing line 15;

[0031] A preset overlap line is drawn on both the second lining material 9 and the second supporting separator 11, and the second lining material 9 and the second supporting separator 11 are overlapped along the preset overlap line in sequence to form a second sewing line 17;

[0032] The first sewing line 15 and the second sewing line 17 correspond to each other.

[0033] In order to sew the first supporting separator cloth 4 to the first bile material 2 and the second supporting separator cloth 11 to the second bile material 9, it is necessary to preset overlapping lines on the first bile material 2 and the second bile material 9 to determine the positions of the first supporting separator cloth 4 and the second supporting separator cloth 11 and make them correspond to each other better.

[0034] It should be understood that the first supporting separator cloth 4 may have a certain bending area so as to contact the first bile material 2, and the bending area of ​​the first supporting separator cloth 4 should have a certain width so as to be sufficient to sew the first supporting separator cloth 4 in subsequent steps.

[0035] Similarly, the second supporting separator 11 may also have a certain bending area so as to contact the second bile material 9, and the bending area of ​​the second supporting separator 11 should have a certain width so as to be sufficient to sew the second supporting separator 11 in subsequent steps.

[0036] A person skilled in the art can determine the position of the first sewing line 15 according to the overlapping area of ​​the first lining material 2 and the first supporting separator cloth 4. Similarly, a person skilled in the art can determine the position of the second sewing line 17 according to the overlapping area of ​​the second lining material 9 and the second supporting separator cloth 11.

[0037] S2, sewing the first liner material 2 and the first supporting separator fabric 4 together along a preset coincidence line, and forming a first needle hole 6 area on the first sewing line 15;

[0038] The second liner material 9 and the second supporting separator fabric 11 are sewn together along a preset coincidence line, and a second needle hole 13 area is formed on the second sewing line 17;

[0039] After sewing, the first sewing line 15 appears on the first supporting separator 4 and the first lining material 2; the second sewing line 17 appears on the second supporting separator 11 and the second lining material 9. When sewing is completed, the first supporting separator 4 and the second supporting separator 11 can be rotated and erected with the straight lines where the first sewing line 15 and the second sewing line 17 are located as axes.

[0040] S3. Place one side of the first supporting separator cloth 4 of the first bile material 2 and one side of the second supporting separator cloth 11 of the second bile material 9 opposite to each other, and at the same time make the first supporting separator cloth 4 and the second supporting separator cloth 11 correspond to each other; the correspondence here allows the first supporting separator cloth 4 and the second supporting separator cloth 11 to be on the same plane, rather than vertically corresponding, to ensure that subsequent operations can continue.

[0041] S4, sewing the first supporting partition cloth 4 and the second supporting partition cloth 11 together.

[0042] The seams may be joined by one or more seam joining methods including flat seams, split seams, fixed seams, divided seams, overlap seams, row seams, rolled seams, inner seams, etc., without any limitation here.

[0043] After the seams are joined, the first supporting separator cloth 4 and the second supporting separator cloth 11 are both in an upright state. At this time, a filling chamber 16 is formed between the first supporting separator cloth 4 and the second supporting separator cloth 11, the first bile material 2, and the second bile material 9 after the seams are joined. The filling chamber 16 is used to fill the filler. The filling chamber 16 is located on both sides of the first supporting separator cloth 4 and the second supporting separator cloth 11 after the seams are joined.

[0044] It should be understood that the first bile material 2, the second bile material 9, and the bending areas of the first supporting separator cloth 4 and the second supporting separator cloth 11 mentioned above can all serve as edge areas constituting the filling chamber 16 and directly contact the filler.

[0045] In one embodiment of the present application, one side of the first supporting separator 4 is sewn to the first sewing line 15, and the opposite side of the first supporting separator 4 can be sewn to the second supporting separator 11, or can be sewn to the second supporting separator 11 at a position close to the second sewing line 17. At the same time, one side of the second supporting separator 11 is sewn to the second sewing line 17, and the opposite side of the second supporting separator 11 can be sewn to the first supporting separator 4, or can be sewn to the first supporting separator 11 at a position close to the first sewing line 15. At this time, a tubular cavity may be generated in the middle of the first supporting separator 4 and the second supporting separator 11, and the cavity can also be filled with fillers to improve the comfort of the down jacket.

[0046] In one embodiment of the present application, a first adhesive strip 3 may be provided between the first liner material 2 and the first supporting separator cloth 4. It should be understood that one side of the first adhesive strip 3 is in contact with the bending area of ​​the first supporting separator cloth 4, and the other side is in contact with one side of the first liner material 2. Similarly, a second adhesive strip 10 may be provided between the second liner material 9 and the second supporting separator cloth 11. It should be understood that one side of the second adhesive strip 10 is in contact with the second supporting separator cloth 11, and the other side is in contact with one side of the second liner material 9. With such a configuration, a person skilled in the art can sew the first liner material 2, the first adhesive strip 3, and the first supporting separator cloth 4 together along the first sewing line 15, and form a first needle hole 6 area on the first sewing line 15; a person skilled in the art can sew the second liner material 9, the second adhesive strip 10, and the second supporting separator cloth 11 together along the second sewing line 17, and form a second needle hole 13 area on the second sewing line 17.

[0047] When the first supporting separator 4 is erected, the edge of the bending area of ​​the first supporting separator 4 on one side where the bending area is located may completely cross the first adhesive strip 3, or may overlap with the edge of the first adhesive strip 3, or may not cross the first adhesive strip 3; the other side of the first supporting separator 4 may overlap with the other edge of the first adhesive strip 3, or may cross or not cross the other edge of the first adhesive strip 3. The positional relationship between the bending area of ​​the first supporting separator 4 and the first adhesive strip 3 may be confirmed and fixed in step S1 and step S2;

[0048] Similarly, on one side where the bending area of ​​the second adhesive strip 10 is located, the edge of the bending area may completely cross the second adhesive strip 10, may overlap with the edge of the second adhesive strip 10, or may not cross the second adhesive strip 10; the other side of the second supporting separator 11 may overlap with the other edge of the second adhesive strip 10, or may cross or not cross the other edge of the second adhesive strip 10. The positional relationship between the bending area of ​​the second supporting separator 11 and the second adhesive strip 10 may be confirmed and fixed in step S1 and step S2.

[0049] In one embodiment of the present application, the first sealing strip 5 may be placed above the first sewing line 15 area on the side where the first supporting separator 4 is located, and completely cover the first sewing line 15 and the first needle hole 6 area, so as to pre-bond the first sewing line 15 and the first needle hole 6 area;

[0050] The second sealing strip 12 can also be placed above the second stitching line 17 area on the side where the second supporting separator cloth 11 is located, and completely cover the second stitching line 17 and the second needle hole 13 area, so as to pre-bond the second stitching line 17 and the second needle hole 13 area.

[0051] After the first liner 2, the first adhesive strip 3, and the first supporting separator 4 are sewn, the first stitching line 15 and the first needle hole 6 area appear on the first liner 2 and the first supporting separator 4, the first sealing strip 5 is in direct contact with the first supporting separator 4, and the first sealing strip 5 completely covers the first stitching line 15 and the first needle hole 6, and at the same time, the first stitching line 15 and the first needle hole 6 are at a certain distance from the edge of the first sealing strip 5 in any direction on the plane, so that the first sealing strip 5 can completely seal the first stitching line 15 and the first needle hole 6. And it should be understood that for the erection area of ​​the first supporting separator 4, the other side of the bending area of ​​the first supporting separator 4 can also be placed with a sealing strip to cover the seam of the first supporting separator 4 and the first adhesive strip 3 to achieve a better sealing effect. Due to the positional relationship between the bending area of ​​the first supporting separator 4 and the first adhesive strip 3 mentioned above, the positional relationship between the edge of the first sealing strip 5 and the edge of the bending area of ​​the first supporting separator 4 and the edge of the first adhesive strip 3 is not limited here.

[0052] Similarly, after sewing the second lining material 9, the second adhesive strip 10, and the second supporting separator 11, the second stitching line 17 and the second needle hole 13 area appear on the second fabric 8 and the second supporting separator 11, and the second sealing strip 12 is in direct contact with the second supporting separator 11, and the second sealing strip 12 completely covers the second stitching line 17 and the second needle hole 13 area, and at the same time, the second stitching line 17 and the second needle hole 13 area have a certain distance from the edge of the second sealing strip 12 in any direction on the plane, so that the second sealing strip 12 can completely seal the second stitching line 17 and the second needle hole 13. And it should be understood that for the erection area of ​​the second supporting separator 11, the other side of the bending area of ​​the second supporting separator 11 can also be placed with a sealing strip to cover the seam between the second supporting separator 11 and the second adhesive strip 10 to achieve a better sealing effect. Due to the positional relationship between the bending area of ​​the second supporting separator 11 and the second adhesive strip 10 described above, the positional relationship between the edge of the second sealing strip 12 and the edge of the bending area of ​​the second supporting separator 11 and the edge of the second adhesive strip 10 is not limited here.

[0053] Because after the sewing in step S2, relative to the first lining material 2, the first sewing line 15 and the first needle hole 6 area will appear on the first lining material 2 on the other side of the first supporting separator 4, therefore, in one embodiment of the present application, the first sealing strip 5 can also be arranged above the first sewing line 15 and the first needle hole 6 area on the first lining material 2, and completely cover the first sewing line 15 and the first needle hole 6 area, and pre-bond the first sewing line 15 and the first needle hole 6 area;

[0054] Relative to the second liner material 9, on the other side of the second supporting dividing cloth 11, the second stitching line 17 and the second needle hole 13 area will appear on the second liner material 9. Therefore, in one embodiment of the present application, the second sealing strip 12 can also be arranged above the second stitching line 17 and the second needle hole 13 area on the second liner material 9, and completely cover the second stitching line 17 and the second needle hole 13 area, and pre-bond the second stitching line 17 and the second needle hole 13 area.

[0055] In one embodiment of the present application, the first fabric 1 is arranged on the other side of the first supporting separator 4 relative to the first bile material 2, and the second fabric 8 is arranged on the other side of the second supporting separator 11 relative to the second bile material 9.

[0056] Since the first material 2 and the second material 9 need to directly contact the filler in the filling chamber 16, and the first fabric 1 and the second fabric 8 can be directly observed, the fabrics and the materials perform different functions. Therefore, the material of the first fabric 1 can be different from the material of the first material 2, the material of the second fabric 8 can be different from the material of the second material 9, and the material of the first material 2 and the second material 9 can be the same. Preferably, the material of the first material 2 is the same as the material of the second material 9.

[0057] In one embodiment of the present application, the material of the first fabric 1 and the material of the second fabric 8 can be different. For example, in a down jacket, the first fabric 1 is the fabric that can be seen by others when the user is using it (or called the outer side of the down jacket). The first fabric 1 can use, for example, technological materials with printed patterns or polyester materials to provide the first fabric 1 with aesthetics, or rain and snow protection, or wear resistance and other functions; and the second fabric 8 is the fabric that cannot be seen by others when the user is using it (or called the inner side of the down jacket). The second fabric can use, for example, flannel or wool materials to provide additional warmth for the down jacket.

[0058] In one embodiment of the present application, the first fabric 1 and the first lining material 2 are sewn together. In step S1, as Figure 1 As shown, preset overlap lines can be marked on the first fabric 1, the first liner material 2, and the first supporting separator 4, and after they are stacked in sequence, they are sewn together according to the preset overlap lines, or the first fabric 1, the first liner material 2, the first adhesive strip 3, and the first supporting separator 4 are stacked in sequence and sewn together according to the preset overlap lines to form the first sewing line 15.

[0059] In one embodiment of the present application, the second fabric 8 and the second lining material 9 are sewn together. In step S1, as Figure 1 As shown, preset overlap lines can be marked on the second fabric 8, the second liner material 9, and the second supporting separator 11, and after they are stacked in sequence, they are sewn together according to the preset overlap lines, or the second fabric 8, the second liner material 9, the second rubber strip 10, and the second supporting separator 11 are stacked in sequence and sewn together according to the preset overlap lines to form the second sewing line 17.

[0060] In an embodiment of the present application, as described above, the first bladder material 2, the first glue strip 3, and the first support partition cloth 4 can be stacked in the above order and then sewn together along a preset coincidence line to form the first sewing line 15. At this time, it should be understood that the area where the first sewing line 15 is located should only occupy a part of the first bladder material 2. If the area of the first bladder material 2 is large, the first bladder material 2 and the first fabric 1 can be sewn at a position on the first bladder material 2 away from the first sewing line 15. Similarly, if the area of the second bladder material 9 is large, the second bladder material 9 and the second fabric 8 can be sewn at a position on the second bladder material 9 away from the second sewing line 17. In this way, a plurality of support partition cloths and a plurality of filling chambers 16 separated by the support partition cloths can be provided, and at the same time, only a small amount of sewing is required to fix the fabric and the bladder material. There will only be a small amount of sewing lines and pinhole marks on the first fabric 1 and the second fabric 8, making the appearance of the down jacket more beautiful.

[0061] Preferably, sewing the fabric and the bladder material will not damage the integrity of the filling chamber 16, that is, the fabric, the bladder material, the sewing line, and the pinhole will not cause the down in the filling chamber 16 to leak.

[0062] For example, as described above, filling chambers 16 are formed on both sides of the support partition cloth after sewing. When a plurality of support partition cloths are arranged on the bladder material (such as sewing a plurality of support partition cloths in parallel, or sewing the support partition cloths in a "field" shape), when sewing, a plurality of filling chambers 16 (filling chambers 16 arranged in parallel, or filling chambers 16 in a "field" shape) will be generated. At this time, the filling chamber 16 is composed of two side strips and two bladder materials, or the filling chamber 16 is composed of four side strips and two bladder materials. Therefore, the sewing area of the fabric and the bladder material on the bladder material can be located in the area outside the filling chamber 16.

[0063] In an embodiment of the present application, when the sewing method has glue strips and sealing strips, the first glue strip 3 and the first sealing strip 5 are press-bonded. A first bonding area 7 is generated at the position of the first glue strip 3, and the first glue strip 3 and the first sealing strip 5 after press-bonding together form a first sealing area; the second glue strip 10 and the second sealing strip 12 are press-bonded. A second bonding area 14 is generated at the position of the second glue strip 10, and the second glue strip 10 and the second sealing strip 12 after press-bonding together form a second sealing area.

[0064] It should be understood that the first glue strip 3, the first sealing strip 5, the second glue strip 10, and the second sealing strip 12 should be rubber materials applicable to the textile field.

[0065] In the present application, the pressing and ironing bonding means that under the action of pressure and temperature, the adhesive material that can be used in the textile field is thermally dissolved and becomes sticky, or the adhesive material penetrates into the fabric or cloth, and after the adhesive material is cooled and solidified, the fabric can obtain a good fixed shape state or a waterproof and windproof state in the adhesive area. It should be understood that after the pressing and ironing bonding, both sides of the adhesive strip will become sticky, while after the pressing and ironing bonding, the sealing strip will only become sticky on one side, and the other side can be a smooth surface without stickiness.

[0066] After pressing and bonding, the first adhesive strip 3 is thermally dissolved and becomes sticky, so that the first supporting separator cloth 4 can be completely bonded to the first bile material 2, so that the first adhesive strip 3 becomes the first bonding area 10, and the first sealing strip 5 is thermally dissolved to completely seal the first sewing line 15 and the first needle hole 6 on the first supporting separator cloth 4.

[0067] Similarly, the second adhesive strip 10 is thermally dissolved and becomes sticky, so that the second supporting separator cloth 11 can be completely bonded to the second bile material 9, so that the second adhesive strip 10 becomes the second bonding area 14, and the second sealing strip 12 is thermally dissolved to completely seal the second sewing line 17 and the second needle hole 13 area on the second supporting separator cloth 11.

[0068] After pressing and bonding, the first sewing line 15 and the first needle hole 6 area on the first supporting separator 4, and the second sewing line 17 and the second needle hole 13 area on the second supporting separator 11 can be sealed by the first sealing strip 5 and the second sealing strip 12 respectively, preventing the possibility of the filler running out through the sewing line and the needle hole. Since the first supporting separator 4 and the second gallbladder material 2 are completely bonded by the first adhesive strip 3, the second supporting separator 11, and the second gallbladder material 9 by the second adhesive strip 10, it is possible to prevent the filler from drilling out through the gap between the gallbladder material and the supporting separator. That is, the viscosity generated by the adhesive strip will only affect the adjacent supporting separators and gallbladder materials, or interact with the viscosity generated by the sealing strip, but will not adhere to the filler in the filling chamber 16.

[0069] It should be understood that when the edge of the first sealing strip 5 passes over the edge of the bending area of ​​the first supporting and separating cloth 4, that is, when the first sealing strip 5 contacts the first adhesive strip 3, or even contacts the first bladder material 2 beyond the first adhesive strip 3, the sealing effect of the first sewing line 15 and the first needle hole 6 on the first supporting and separating cloth 4 will be further improved after pressing and gluing, and the same is true for the second sealing strip 12. That is, the viscosity generated by the sealing strip will only affect the above-mentioned lining strip, or adhesive strip, or bladder material, and the smooth surface on the other side has no viscosity and directly contacts the filler in the filling chamber 16.

[0070] Therefore, it should be understood that this document does not impose any restrictions on the relationship between the edge of the sealing strip and the edge of the bending area of ​​the supporting separator cloth and the edge of the coating strip. Therefore, after the pressing and gluing process, the form of the sealing area formed by the sealing strip and the coating strip may not be restricted. However, in one embodiment of the present application, the width of the first sealing area is 0.5cm-1cm, and the width of the second sealing area is 0.5-1cm. Preferably, the width of the first sealing area is equal to the width of the second sealing area. This reduces the use of the coating strip and the sealing strip, and can also reduce the weight of the textile, and can ensure the sealing effect of the filling chamber 16.

[0071] Through such sewing method, through pressing and bonding, the supporting separator cloth and the rubber strip between the first lining material 2 and the second lining material 9, any stitching lines, pinholes, and stitching edges caused by sewing will be well sealed or bonded. The filling material cannot escape through the stitching lines and pinholes in any way. At the same time, from the surface of the down product, the sewing method of the present application only leaves a small amount of stitching lines on the first fabric 1 and the second fabric 8, which will not damage the printed pattern on the surface of the fabric, and maximizes the beauty and uniformity of the appearance of the first fabric 1 and the second fabric 8.

[0072] In one embodiment of the present application, the first supporting separator cloth 4 and the second supporting separator cloth 11 are of equal width. Such an arrangement can make the first supporting separator cloth 4 and the second supporting separator cloth 11 symmetrical with each other, which is beneficial to the seaming operation of the supporting separator cloths, and facilitates the mass production of the supporting separator cloths, improves work efficiency, and at the same time enables the textile to remain flat after manufacturing, reduces the possibility of unevenness on the surface of the textile, and further improves comfort.

[0073] In one embodiment of the present application, the first lining material 2 may not be provided on the surface of the first fabric 1, and the second lining material 9 may not be provided on the surface of the second fabric 8. In this case, the first fabric 1 will simultaneously play the role of the first lining material 2, and the second fabric 8 will simultaneously play the role of the second lining material 9. The amount of fabric used in the textile is reduced, the weight of the textile can be reduced to a certain extent, and the comfort of the textile when used can be improved.

[0074] In one embodiment of the present application, the first supporting separator cloth 4 and the second supporting separator cloth 11 are both single-layer structures.

[0075] from Figure 1It can be seen that the support partition cloth after sewing separates two filling chambers 16. In one embodiment of the present application, as described above, multiple support partition cloths can be sewn using the sewing method of the present application to separate multiple filling chambers 16. The number of the filling chambers 16 is 2-30, for example, the number of the filling chambers 16 can be 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30. When the number of the filling chambers 16 is small, the volume of the filling chamber 16 becomes larger, and the filling material is easily unevenly distributed in the filling chamber 16, which may affect the comfort of the down jacket.

[0076] The present application also provides a down jacket, characterized in that the down jacket is sewn using any of the methods described above.

[0077] Example

[0078] like Figure 1 As shown, the first fabric 1, the first liner material 2, the first adhesive strip 3, and the first supporting separator 4 are stacked in sequence and sewn to produce a first sewing line 15 and a first needle hole 6 area; the second fabric 8, the second liner material 9, the second adhesive strip 10, and the second supporting separator 11 are stacked in sequence and sewn to produce a second sewing line 17 and a second needle hole 13 area;

[0079] A first sealing strip 5 is placed on the first supporting separator 4 for pre-bonding, and a second sealing strip 12 is placed on the second supporting separator 11 for pre-bonding. With respect to the first supporting separator 4, no sealing strip is placed on the other side of the bend; with respect to the second supporting separator 11, no sealing strip is placed on the other side of the bend;

[0080] The first supporting and separating cloth 4 and the second supporting and separating cloth 11 are joined together to form a filling chamber 16;

[0081] The adhesive strip and the sealing strip are pressed and glued to generate the first bonding area 7 and the second bonding area 14. It should be understood that after pressing and gluing, the adhesive strip will bond the adjacent gallbladder material and the supporting separator cloth together, and the sealing strip will completely seal the sewing lines and pinholes on the supporting separator cloth. And as shown in the figure, the edge of the first sealing strip 5 does not cross the first adhesive strip 3, and the edge of the second sealing strip 12 does not cross the second adhesive strip 10. In this case, the width of the generated first bonding area 7 is actually the width of the first adhesive strip 3, and the first bonding area 7 is the first sealing area; the width of the second adhesive area 14 is actually the width of the second adhesive strip 10, and the second bonding area 14 is the second sealing area. The width of the first bonding area 7 is equal to the width of the second bonding area 14, and both are 0.5cm-1cm.

[0082] By sewing in this way, the filling in the filling chamber 16 cannot leak through any gap, sewing line or needle hole, thus achieving complete isolation of the filling by the needle hole sewing line, and completely solving the problem of needle hole leakage. In addition, only the first fabric 1 and the second fabric 8 can be seen from the outside, with only the first sewing line 15 and the first needle hole 6 area, and the second sewing line 17 and the second needle hole area 13, ensuring the beauty and neatness of the first fabric 1 and the second fabric 8.

[0083] The above is only the preferred embodiment of the present application, and does not limit the present application in other forms. Any technician familiar with the profession may use the above disclosed technical content to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present application without departing from the technical solution of the present application still falls within the protection scope of the technical solution of the present application.
