Processing method of seamless hinges
[0001] This application claims priority to Chinese Patent Application No. 202411991518.6, filed with the Chinese Patent Office on December 31, 2024, entitled “Method for Processing Seamless Loose-leaf Brushes”, the entire contents of which are incorporated herein by reference. Technical Field
[0002] This invention relates to the field of garment manufacturing technology, and in particular to a method for processing seamless hinges. Background Technology
[0003] In the existing technology, some styles of clothing need to be processed with seamless hinges during the production process. Hinges refer to movable parts of the clothing such as pockets and plackets. The outer surface of the seamless hinges needs to meet the appearance requirements of seamless stitching. Therefore, the side of the outer layer facing the inner layer cannot be fixed to the inner layer by stitching. As a result, when the user wears the clothing, the inner layer is easily exposed due to the outer layer being pulled, which affects the wearing effect.
[0004] Therefore, to ensure the wearing effect, existing technologies generally use methods such as adding a seam allowance to the inner layer fabric or directly bonding the outer layer fabric and the inner layer fabric with double-sided adhesive.
[0005] Specifically, regarding the method of adding a drawstring to the inner fabric, as shown in Figure 1, one end of the drawstring 6 is sewn to the edge of the inner fabric near the edge of the seam 5 used for sewing the looper opening. The looper opening is the opening formed between the looper and the garment body. For example, for a pocket, the looper opening is the pocket entrance. The looper opening seam 5 is located at the looper opening, and the outer edges of the outer and inner fabrics are sewn together to form a complete looper. Again, taking a pocket as an example, the looper opening seam 5 is the seam located on the edge of the looper. Located at the edge of the outer and inner layers of fabric, and used to sew the outer and inner layers together, the other end of the pull strip 6 is sewn onto the inner layer of fabric near the center front line 7 of the garment. Because the length of the pull strip 6 is difficult to control, the pull strip 6 sewn onto the inner layer of fabric is prone to being too long or too short. When the pull strip 6 is too long, the inner layer of the flap is prone to being exposed due to being pulled by the end of the pull strip 6 near the outer edge of the flap seam 5. When the pull strip 6 is too short, the inner layer of fabric is prone to bunching up and becoming uneven after the pull strip 6 is sewn, thus affecting the appearance of the garment.
[0006] When directly bonding the outer and inner fabrics with double-sided tape, the outer edges of the two fabrics must be aligned during the bonding process to ensure proper seam stitching of the flap. This requires precise application of either the outer or inner fabric to the other side of the tape, making the process difficult. Furthermore, directly bonding the outer and inner fabrics to the tape can cause bubbling in the flap, affecting the wearing experience. Summary of the Invention
[0007] The purpose of this invention is to provide a seamless hinge processing method that is easy to operate and can prevent the inner layer fabric from being exposed while avoiding problems such as arching, unevenness, and bubbling on the garment.
[0008] To achieve this objective, the present invention adopts the following technical solution:
[0009] The processing methods for seamless hinges include:
[0010] One side of the double-sided adhesive is attached to the inner surface of the outer fabric, and the outer edge of the double-sided adhesive is aligned with the edge of the outer fabric used for sewing the outer opening of the flap.
[0011] A lining is adhered to the other side of the double-sided adhesive, the lining covering the inner edge of the double-sided adhesive;
[0012] An inner layer fabric is covered on the side of the lining fabric away from the double-sided adhesive, and the outer edge of the inner layer fabric is aligned with the edge of the outer layer fabric used for sewing the outer opening seam. The outer edge of the inner layer fabric is then sewn to the edge of the outer layer fabric used for sewing the outer opening seam to form the outer opening seam.
[0013] The portion of the lining fabric that extends beyond the inner edge of the double-sided adhesive is sewn together with the inner layer fabric.
[0014] Optionally, a slit area is reserved on the other side of the double-sided adhesive, the slit area being adjacent to the edge of the outer fabric used for sewing the outer opening seam, and the inner fabric is bonded to the side of the slit area away from the edge of the outer fabric used for sewing the outer opening seam;
[0015] After sewing the outer edge of the inner fabric to the edge of the outer fabric used for sewing the flap opening seam, the inner fabric is glued to the slit area.
[0016] Optionally, the width of the slit area is 0.6 cm, so that there is a 0.6 cm gap between the outer edge of the inner lining and the edge of the outer layer fabric used for sewing the outer opening of the flap.
[0017] Optionally, after one side of the double-sided adhesive is bonded to the inner surface of the outer fabric, a dividing line is laser-etched on the other side of the double-sided adhesive along a direction parallel to the edge of the outer fabric used for sewing the outer opening of the loose-leaf. The dividing line divides the protective film bonded to the other side of the double-sided adhesive into a first film and a second film. The first film is located on the side of the dividing line away from the edge of the outer fabric used for sewing the outer opening of the loose-leaf, and the second film is located on the side of the dividing line close to the edge of the outer fabric used for sewing the outer opening of the loose-leaf.
[0018] Remove the first film paper and attach the inner lining to the side of the dividing line away from the edge of the outer fabric used for sewing the outer opening seam.
[0019] Optionally, after sewing the outer edge of the inner fabric to the edge of the outer fabric used for sewing the flap opening seam, the second film paper is removed, and the inner fabric is bonded to the double-sided adhesive.
[0020] Alternatively, the inner layer fabric can be bonded to the double-sided adhesive by pressing with a heat press.
[0021] Alternatively, the outer fabric can be bonded to the double-sided adhesive by pressing with a heat press.
[0022] Alternatively, the inner fabric can be bonded to the double-sided adhesive by pressing with a heat press.
[0023] Optionally, the inner edge of the inner layer fabric is aligned with the inner edge of the lining fabric.
[0024] Alternatively, along a direction parallel to the edge of the seam used to sew the outer flap of the outer fabric.
[0025] The portion of the lining fabric that extends beyond the inner edge of the double-sided adhesive is sewn together with the inner layer fabric.
[0026] The beneficial effects of this invention are:
[0027] This invention involves bonding a lining fabric to the inner surface of the outer fabric. The lining fabric provides a sewing point for the inner fabric, allowing it to be sewn onto the side of the lining fabric facing away from the outer fabric. This secures the outer fabric facing the inner fabric to the inner fabric facing the outer fabric, ensuring that when the garment is worn, if the outer fabric is pulled, the inner fabric is pulled along with it, preventing the inner fabric from being exposed and affecting the wearing experience. Furthermore, since only one side of the double-sided adhesive is fully bonded to the outer fabric, it prevents bubbling. Additionally, because the lining fabric does not need to extend to the center front seam, its dimensions are easier to control, preventing unevenness and arching in the garment. This invention also reduces the number of stitches and simplifies alignment, thus reducing operational difficulty. Attached Figure Description

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.
[0037] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0039] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.
[0040] Based on the above, some garment styles require seamless flaps to be processed during the production process. This embodiment takes a pocket as an example. In the prior art, a stitching strip is usually added to the inner layer of the seamless flap or the outer and inner layers of the seamless flap are directly glued together with double-sided adhesive to prevent the inner layer from being easily exposed due to the outer layer being pulled when the user wears the garment, thus avoiding affecting the wearing effect.
[0041] As shown in Figure 1, when adding a pull strip to the inner fabric, one end of the pull strip 6 is sewn onto the inner fabric near the edge of the seam 5 used to sew the flap, while the other end is sewn onto the inner fabric near the center front line 7 of the garment. Since the length of the pull strip 6 is difficult to control, it is easy for the pull strip 6 sewn onto the inner fabric to be too long or too short. When the pull strip 6 is too long, the inner fabric of the flap is easily exposed due to being pulled by the end of the pull strip 6 near the seam 5 of the flap. When the pull strip 6 is too short, the inner fabric is prone to bunching up and becoming uneven after the pull strip 6 is sewn on, thus affecting the appearance of the garment.
[0042] When directly bonding the outer and inner fabrics of a seamless zipper using double-sided tape, it is crucial to ensure that the outer edges of the seams used for sewing the zipper opening on the outer fabric are aligned with the outer edges of the seams used for sewing the zipper opening on the inner fabric. This requires extremely precise bonding on both sides, making the process difficult. Furthermore, directly bonding the outer and inner fabrics to the two sides of the double-sided tape can easily cause bubbles to form in the zipper, thus affecting the wearing experience.
[0043] To solve the above problems, please refer to Figures 2 to 7, and in conjunction with Figure 1, this embodiment provides a method for processing seamless loose-leaf sheets. The method for processing seamless loose-leaf sheets includes:
[0044] First, attach one side of the double-sided adhesive 1 to the inner surface of the outer fabric 2, and align the outer edge of the double-sided adhesive 1 with the edge of the outer fabric 2 for sewing the outer opening of the loose-leaf. The outer edge of the double-sided adhesive 1 and the edge of the outer fabric 2 for sewing the outer opening of the loose-leaf are respectively the first edge 15 and the second edge 21. When attaching one side of the double-sided adhesive 1 to the inner surface of the outer fabric 2, align the first edge 15 and the second edge 21.
[0045] It is understood that in this embodiment, the outer side is the side closest to the side seam 8 of the garment after it is made, and the inner side is the side closest to the center front line 7 of the garment after it is made.
[0046] Next, the inner lining fabric 3 is adhered to the other side of the double-sided adhesive 1. The inner lining fabric 3 covers the inner edge of the double-sided adhesive 1. Taking the inner edge of the double-sided adhesive 1 as the third edge 16, the third edge 16 is opposite to the first edge 15, and the inner lining fabric 3 covers the third edge 16. Exemplarily, in this embodiment, the inner lining fabric 3 is a voile inner lining fabric.
[0047] Then, cover the inner layer fabric 4 on the side of the liner 3 away from the double-sided adhesive 1, and align the outer edge of the inner layer fabric 4 with the edge of the outer layer fabric 2 used for sewing the outer opening seam 5. The outer edge of the inner layer fabric 4 is referred to as the fourth edge 41. The fourth edge 41 is aligned with the second edge 21. Then, sew the outer edge of the inner layer fabric 4 to the edge of the outer layer fabric 2 used for sewing the outer opening seam 5, that is, sew the fourth edge 41 and the second edge 21 together to form the outer opening seam 5.
[0048] It is understandable that the outer layer fabric 2 is the outer fabric of the front piece of the garment. After the fourth edge 41 and the second edge 21 are sewn together, the outer layer fabric 2 and the inner layer fabric 4 are sewn together. After the outer fabric and the inner fabric of the front piece are sewn together, the opening seam 5 of the flap and the inner fabric form the entrance of the pocket, i.e. the flap opening.
[0049] Finally, the part of the lining 3 that extends beyond the inner edge of the double-sided adhesive 1 is sewn together with the inner layer fabric 4. That is, the part of the lining 3 located outside the double-sided adhesive 1 is sewn together with the inner layer fabric 4, thereby fixing the inner layer fabric 4 and the lining 3 together.
[0050] Therefore, in this embodiment, a layer of lining fabric 3 is first bonded to the inner surface of the outer layer fabric 2, and then the inner layer fabric 4 is sewn onto the side of the lining fabric 3 facing away from the outer layer fabric 2. The lining fabric 3 is used to provide a sewing position for the inner layer fabric 4, thereby fixing the side of the outer layer fabric 2 facing the inner layer fabric 4 and the side of the inner layer fabric 4 facing the outer layer fabric 2. This ensures that when the user wears the garment, if the outer layer fabric 2 is pulled, the inner layer fabric 4 can be pulled along with the outer layer fabric 2, rather than only the side of the inner layer fabric 4 near the outer edge seam 5 being pulled, thus preventing the inner layer fabric 4 from being exposed and avoiding affecting the wearing effect. Furthermore, the inner lining 3 does not need to extend to the center front line 7, making its dimensions easier to control and thus avoiding the problem of uneven arching of the inner lining 4. In addition, this embodiment only requires sewing one seam on the inner lining 3, thereby reducing sewing and alignment time. Moreover, this embodiment only aligns the double-sided adhesive 1 and the outer lining 2 when one side of the double-sided adhesive 1 is adhered to the inner surface of the outer lining 2, without needing to align the double-sided adhesive 1 and the inner lining 4 in the subsequent process, thus reducing the difficulty of operation. Furthermore, this embodiment only ensures that one side of the double-sided adhesive 1 is completely adhered to the outer lining 2, thereby avoiding the problem of bubbles forming in the loose-leaf binding.
[0051] In this embodiment, a lining fabric 3 is bonded to the inner surface of the outer layer fabric 2. The lining fabric 3 provides a sewing position for the inner layer fabric 4, allowing the inner layer fabric 4 to be sewn onto the side of the lining fabric 3 facing away from the outer layer fabric 2. This fixes the side of the outer layer fabric 2 facing the inner layer fabric 4 to the side of the inner layer fabric 4 facing the outer layer fabric 2. Consequently, when the user wears the garment, if the outer layer fabric 2 is pulled, the inner layer fabric 4 can be pulled along with the outer layer fabric 2, preventing the inner layer fabric 4 from being exposed and thus avoiding affecting the wearing effect. Moreover, in this embodiment, only one side of the double-sided adhesive 1 is completely adhered to the outer layer fabric 2, thereby preventing the garment from bubbling. In addition, since the lining fabric 3 does not need to extend to the center front line 7, its size is easier to control, thus avoiding unevenness and arching on the garment. At the same time, this embodiment reduces the number of stitches and simplifies the alignment operation, thereby reducing the difficulty of operation.
[0052] Furthermore, when attaching the inner fabric 3 to the double-sided adhesive 1, a slit area 11 is first reserved on the other side of the double-sided adhesive 1. The slit area 11 is adjacent to the edge of the outer fabric 2 used for sewing the outer opening seam 5, that is, the slit area 11 is set adjacent to the second edge 21. In this embodiment, the inner fabric 3 is attached to the side of the slit area 11 away from the edge of the outer fabric 2 used for sewing the outer opening seam 5. That is, in this embodiment, the inner fabric 3 is attached to the side of the slit area 11 away from the second edge 21, thereby reserving a slit area 11 between the inner fabric 3 and the second edge 21. After sewing the outer edge of the inner fabric 4 to the edge of the outer fabric 2 used for sewing the outer opening seam 5, the inner fabric 4 is attached to the slit area 11.
[0053] Therefore, in this embodiment, the part of the inner fabric 4 near the outer edge seam 5 of the hinge is bonded to the double-sided adhesive 1, thereby more effectively ensuring that when the outer fabric 2 is pulled, the part of the inner fabric 4 near the outer edge seam 5 of the hinge can be pulled along with the outer fabric 2 and will not be exposed. That is, this embodiment can more effectively prevent the inner fabric 4 from being exposed.
[0054] Furthermore, since this embodiment only bonds the part of the inner fabric 4 near the outer seam 5 of the hinge to the double-sided adhesive 1, that is, only a small part of the inner fabric 4 is bonded to the double-sided adhesive 1, the problem of bubbling can be avoided.
[0055] For example, in this embodiment, the width of the slit area 11 is 0.6 cm, so that there is a 0.6 cm gap between the outer edge of the inner fabric 3 and the edge of the outer fabric 2 used for sewing the outer opening of the flap. Taking the outer edge of the inner fabric 3 as the fifth edge 31 for explanation, in this embodiment, the gap between the fifth edge 31 and the second edge 21 is 0.6 cm, thereby ensuring that the part of the inner fabric 4 near the outer opening of the flap 5 can be bonded to the double-sided adhesive 1 while preventing bubbling.
[0056] Based on the above description, after one side of the double-sided adhesive 1 is bonded to the inner surface of the outer fabric 2, a dividing line 12 is laser-etched on the other side of the double-sided adhesive 1 in a direction parallel to the edge of the outer fabric 2 used for sewing the outer opening of the loose-leaf. The distance between the dividing line 12 and the edge of the outer fabric 2 used for sewing the outer opening of the loose-leaf is 0.6 cm, and the dividing line 12 divides the protective film paper bonded to the other side of the double-sided adhesive 1 into a first film paper 13 and a second film paper 14. The first film paper 13 is located on the side of the dividing line 12 away from the edge of the outer fabric 2 used for sewing the outer opening of the loose-leaf, that is, the first film paper 13 is located on the side of the dividing line 12 away from the second edge 21. The second film paper 14 is located on the side of the dividing line 12 close to the edge of the outer fabric 2 used for sewing the outer opening of the loose-leaf, that is, the second film paper 14 is located on the side of the dividing line 12 close to the second edge 21.
[0057] Next, peel off the first film paper 13 and attach the inner lining cloth 3 to the side of the dividing line 12 away from the edge of the outer fabric 2 used for sewing the outer opening seam 5. That is, after peeling off the first film paper 13, attach the inner lining cloth 3 to the exposed adhesive area on the double-sided tape 1, and align the outer edge of the inner lining cloth 3 with the dividing line 12. That is, align the fifth edge 31 with the dividing line 12. The cutting line can also provide a reference for the alignment of the inner lining cloth 3, thus making the operation simpler.
[0058] Furthermore, it is worth noting that in this embodiment, when covering the inner layer fabric 4, the inner edge of the inner layer fabric 4 is aligned with the inner edge of the lining fabric 3. The inner edge of the inner layer fabric 4 and the inner edge of the lining fabric 3 are described as the sixth edge 42 and the seventh edge 32, respectively. In this embodiment, when covering the inner layer fabric 4, the sixth edge 42 and the seventh edge 32 are aligned. Therefore, this embodiment can accurately determine the size of the lining fabric 3 based on the position of the dividing line 12 and the size of the inner lining fabric 3.
[0059] In addition, based on the above, after sewing the outer edge of the inner fabric 4 to the edge of the outer fabric 2 used for sewing the outer opening seam 5, that is, after sewing the fourth edge 41 and the second edge 21, the second film paper 14 is removed, and then the inner fabric 4 is bonded to the double-sided adhesive 1, so as to avoid the inner fabric 4 sticking to the double-sided adhesive 1 during the sewing process, thereby preventing the bonding position of the inner fabric 4 from being incorrect.
[0060] Furthermore, it is worth noting that in this embodiment, a heat press is used to bond the inner layer fabric 4 to the double-sided adhesive 1, thereby ensuring a firm bond between the inner layer fabric 4 and the double-sided adhesive 1.
[0061] Similarly, in this embodiment, a heat press is used to bond the outer fabric 2 to the double-sided adhesive 1, thereby ensuring that the outer fabric 2 and the double-sided adhesive 1 are firmly bonded.
[0062] Similarly, in this embodiment, a heat press is used to bond the inner fabric 3 to the double-sided adhesive 1, thereby ensuring a firm bond between the inner fabric 3 and the double-sided adhesive 1.
[0063] Furthermore, in this embodiment, the portion of the inner fabric 3 extending beyond the inner edge of the double-sided adhesive 1 is sewn together with the inner fabric 4 along a direction parallel to the edge of the outer fabric 2 for sewing the outer opening seam 5. That is, in this embodiment, the fixing seam 43 between the inner fabric 4 and the inner fabric 3 extends in a direction parallel to the second edge 21. Thus, this embodiment makes it easier to determine the seam between the inner fabric 4 and the inner fabric 3, thereby further simplifying the operation.
[0064] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
