Description

Technical Field

[0001] The invention relates to the technical field of clothing production, in particular to a method for processing a seamless loose-leaf. Background Art

[0002] In the prior art, some styles of clothing require seamless loose-leaf processing during the production process, where the loose-leaf refers to the movable parts of the clothing such as pockets and lapels, and the outer surface of the seamless loose-leaf needs to meet the seamless appearance requirements. Therefore, the side of the outer layer fabric facing the inner layer fabric cannot be fixed to the inner layer fabric by stitching, which results in the inner layer fabric being easily exposed due to the outer layer fabric being pulled when the user wears the clothing, thereby affecting the wearing effect.

[0003] In order to ensure the wearing effect, the prior art generally adopts a method of adding a tie strip to the inner layer fabric or directly bonding the outer layer fabric and the inner layer fabric by double-sided tape.

[0004] Specifically, for the method of adding a stitching strip to the inner layer fabric, Figure 1 As shown, one end of the tie strip 6 is sewn on the inner layer of fabric near the edge of the loose-leaf outer opening seam 5, wherein the loose-leaf outer opening is an opening formed between the loose-leaf and the clothing body. For example, for a pocket, the loose-leaf outer opening is the entrance of the pocket, and the loose-leaf outer opening seam 5 is located at the loose-leaf outer opening, and the outer edges of the outer layer of fabric and the inner layer of fabric are sewn to form a complete loose-leaf. Taking the pocket as an example, the loose-leaf outer opening seam 5 is the seam located on the edge of the loose-leaf, and the seam is located at the edge of the outer layer of fabric and the inner layer of fabric. Along the position, and used to sew the outer layer fabric and the inner layer fabric, the other end of the tie strip 6 is sewn on the inner layer fabric near the front center line 7 of the clothes. Since the length of the tie strip 6 is difficult to control, the tie strip 6 sewn on the inner layer fabric is prone to be too long or too short. When the tie strip 6 is too long, the inner layer fabric of the loose-leaf is easily exposed due to being pulled by one end of the tie strip 6 close to the outer seam line 5 of the loose-leaf. When the tie strip 6 is too short, after the tie strip 6 is sewn, the inner layer fabric is prone to arching and unevenness, thereby affecting the aesthetics of the clothing.

[0005] Regarding the method of directly bonding the outer layer fabric and the inner layer fabric by double-sided tape, since in the process of bonding the outer layer fabric and the inner layer fabric to the two sides of the double-sided tape respectively, it is necessary to ensure that the outer edges of the outer layer fabric and the inner layer fabric remain aligned so as to sew the outer seam of the loose-leaf later, therefore, whether bonding the outer layer fabric to one side of the double-sided tape or bonding the inner layer fabric to the other side of the double-sided tape, both bondings require very precise operations and are difficult to operate. Moreover, directly bonding the outer layer fabric and the inner layer fabric to the two sides of the double-sided tape respectively is likely to cause bubbling problems on the loose-leaf, thereby affecting the wearing effect. Summary of the invention

[0006] The purpose of the present invention is to provide a method for processing a seamless loose-leaf, which has low operating difficulty and can prevent the inner layer of fabric from being exposed while avoiding the problems of unevenness and bubbling on the clothing.

[0007] To achieve this object, the present invention adopts the following technical solutions:

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0036] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0038] In the description of this embodiment, the terms "upper", "lower", "right", "left" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0039] Based on the content mentioned above, some styles of clothing need to be processed with seamless loose-leaf during the production process. Taking pockets as an example in this embodiment, the prior art generally adopts a method of adding a stitching strip to the inner layer fabric of the seamless loose-leaf or directly bonding the outer layer fabric and the inner layer fabric of the seamless loose-leaf with double-sided tape to prevent the inner layer fabric from being easily exposed due to the outer layer fabric being pulled when the user wears the clothing, thereby avoiding affecting the wearing effect.

[0040] For the method of adding a tie strip to the inner layer of fabric, Figure 1As shown, one end of the tie strip 6 is sewn on the inner layer fabric near the edge of the seam line 5 for sewing the outer opening of the loose-leaf, and the other end of the tie strip 6 is sewn on the inner layer fabric near the front center line 7 of the clothing. Since the length of the tie strip 6 is difficult to control, the tie strip 6 sewn on the inner layer fabric is prone to being too long or too short. When the tie strip 6 is too long, the inner layer fabric of the loose-leaf is easily exposed due to being pulled by one end of the tie strip 6 near the seam line 5 of the outer opening of the loose-leaf. When the tie strip 6 is too short, the inner layer fabric is prone to arching and unevenness after the tie strip 6 is sewn, thereby affecting the aesthetics of the clothing.

[0041] Regarding the method of directly bonding the outer layer fabric and the inner layer fabric of the seamless loose-leaf by double-sided tape, in the process of bonding the outer layer fabric and the inner layer fabric to the two sides of the double-sided tape respectively, it is necessary to ensure that the outer edge of the outer layer fabric used for sewing the outer seam of the loose-leaf is aligned with the outer edge of the inner layer fabric used for sewing the outer seam of the loose-leaf. For this reason, both bonding operations require very precise operations, resulting in great difficulty in operation. Moreover, directly bonding the outer layer fabric and the inner layer fabric to the two sides of the double-sided tape respectively can easily cause bubbling problems on the loose-leaf, thereby affecting the wearing effect.

[0042] To solve the above problems, please refer to Figures 2 to 7 , and combined with Figure 1 The present embodiment provides a method for processing a seamless loose-leaf, the method comprising:

[0043] First, adhere one side of the double-sided tape 1 to the inner surface of the outer layer fabric 2, and align the outer edge of the double-sided tape 1 with the edge of the outer layer fabric 2 for sewing the outer seam line 5 of the loose-leaf. The outer edge of the double-sided tape 1 and the edge of the outer layer fabric 2 for sewing the outer seam line 5 of the loose-leaf are respectively described as the first edge 15 and the second edge 21. When adhering one side of the double-sided tape 1 to the inner surface of the outer layer fabric 2, align the first edge 15 and the second edge 21.

[0044] It can be understood that, in this embodiment, the outer side is the side close to the side seam 8 of the garment after the garment is made, and the inner side is the side close to the front center line 7 of the garment after the garment is made.

[0045] Afterwards, the lining cloth 3 is bonded to the other side of the double-sided adhesive tape 1, and the lining cloth 3 covers the inner edge of the double-sided adhesive tape 1, and the inner edge of the double-sided adhesive tape 1 is described as the third edge 16, and the third edge 16 is opposite to the first edge 15, and the lining cloth 3 covers the third edge 16. For example, in this embodiment, the lining cloth 3 is a floating yarn lining cloth.

[0046] Then, the inner layer fabric 4 is covered on the side of the bile cloth 3 away from the double-sided tape 1, and the outer edge of the inner layer fabric 4 is aligned with the edge of the outer layer fabric 2 for sewing the loose-leaf outer seam 5, and the outer edge of the inner layer fabric 4 is described as the fourth edge 41, and the fourth edge 41 is aligned with the second edge 21. After that, the outer edge of the inner layer fabric 4 is sewn with the edge of the outer layer fabric 2 for sewing the loose-leaf outer seam 5, that is, the fourth edge 41 and the second edge 21 are sewn to form the loose-leaf outer seam 5.

[0047] It can be understood that the outer layer fabric 2 is the outer layer 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 into one. Thereafter, after the outer layer fabric and the inner layer fabric of the front piece are sewn together, the entrance of the pocket, i.e., the loose-leaf outer opening, is formed between the loose-leaf outer opening seam 5 and the inner layer fabric.

[0048] Finally, the portion of the bladder cloth 3 that extends beyond the inner edge of the double-sided tape 1 is sewn together with the inner layer cloth 4, that is, the portion of the bladder cloth 3 that is located outside the double-sided tape 1 is sewn together with the inner layer cloth 4, so that the inner layer cloth 4 is fixedly connected to the bladder cloth 3.

[0049] As described above, in this embodiment, a layer of bladder cloth 3 is firstly bonded to the inner surface of the outer layer cloth 2, and then the inner layer cloth 4 is sewn on the side of the bladder cloth 3 facing away from the outer layer cloth 2, wherein the bladder cloth 3 is used to provide a sewing position for the inner layer cloth 4, so that the side of the outer layer cloth 2 facing the inner layer cloth 4 and the side of the inner layer cloth 4 facing the outer layer cloth 2 can be fixed, so that when the user wears the clothing, if the outer layer cloth 2 is pulled, the inner layer cloth 4 as a whole can be pulled together with the outer layer cloth 2, and only the side of the inner layer cloth 4 close to the outer opening seam 5 of the loose-leaf will not be pulled, thereby preventing the inner layer cloth 4 from being exposed, thereby avoiding affecting the wearing effect. Moreover, the bladder cloth 3 does not need to extend to the front center line 7, so its size is easier to control, thereby avoiding the problem of arching and unevenness of the inner layer cloth 4. At the same time, the present embodiment only needs to sew a seam on the bladder cloth 3, thereby reducing the time for sewing and alignment. In addition, the present embodiment only aligns the double-sided tape 1 and the outer layer cloth 2 in the process of bonding one side of the double-sided tape 1 to the inner surface of the outer layer cloth 2, and there is no need to align the double-sided tape 1 and the inner layer cloth 4 subsequently, thereby reducing the difficulty of operation. Moreover, the present embodiment only makes one side of the double-sided tape 1 completely adhere to the outer layer cloth 2, thereby avoiding the problem of bubbling of the loose-leaf.

[0050] That is, in this embodiment, a layer of bile cloth 3 is bonded to the inner surface of the outer layer fabric 2, and the bile cloth 3 is used to provide a sewing position for the inner layer fabric 4, so that the inner layer fabric 4 is sewn on the side of the bile cloth 3 away from the outer layer fabric 2, so that 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 are fixed, so that when the user wears the clothing, if the outer layer fabric 2 is pulled, the inner layer fabric 4 can be pulled along with the outer layer fabric 2 as a whole, so as to prevent the inner layer fabric 4 from being exposed, thereby avoiding affecting the wearing effect, and in this embodiment, only one side of the double-sided tape 1 is completely bonded to the outer layer fabric 2, so as to prevent the clothing from bubbling. In addition, since the bile cloth 3 does not need to extend to the front center line 7, its size is easier to control, so as to avoid the problem of arching and unevenness on the clothing. At the same time, this embodiment can reduce the number of stitches and simplify the alignment operation, so as to reduce the difficulty of operation.

[0051] Furthermore, when bonding the bile cloth 3 to the double-sided tape 1, firstly, a slit area 11 is reserved on the other side of the double-sided tape 1, and the slit area 11 is adjacent to the edge of the outer layer cloth 2 for sewing the outer seam line 5 of the loose-leaf, that is, the slit area 11 is arranged adjacent to the second edge 21. In this embodiment, the bile cloth 3 is bonded to the side of the slit area 11 away from the edge of the outer layer cloth 2 for sewing the outer seam line 5 of the loose-leaf, that is, in this embodiment, the bile cloth 3 is bonded to the side of the slit area 11 away from the second edge 21, thereby reserving the slit area 11 between the bile cloth 3 and the second edge 21, and after sewing the outer edge of the inner layer cloth 4 to the edge of the outer layer cloth 2 for sewing the outer seam line 5 of the loose-leaf, the inner layer cloth 4 is bonded to the slit area 11.

[0052] As described above, in this embodiment, the portion of the inner layer fabric 4 close to the loose-leaf outer seam 5 is bonded to the double-sided tape 1, thereby more effectively ensuring that when the outer layer fabric 2 is pulled, the portion of the inner layer fabric 4 close to the loose-leaf outer seam 5 can be pulled together with the outer layer fabric 2 without being exposed, that is, this embodiment can more effectively prevent the inner layer fabric 4 from being exposed.

[0053] Moreover, since this embodiment only bonds the double-sided tape 1 to the inner layer fabric 4 near the outer seam 5 of the loose-leaf, that is, only a small portion of the inner layer fabric 4 is bonded to the double-sided tape 1, blistering can be avoided.

[0054] Exemplarily, in this embodiment, the width of the slit area 11 is 0.6 cm, so that the outer edge of the bile cloth 3 and the edge of the outer layer fabric 2 for sewing the loose-leaf outer seam 5 have a distance of 0.6 cm. The outer edge of the bile cloth 3 is used as the fifth edge 31 for explanation. From the above, in this embodiment, the distance between the fifth edge 31 and the second edge 21 is 0.6 cm, thereby ensuring that the portion of the inner layer fabric 4 close to the loose-leaf outer seam 5 can be bonded to the double-sided tape 1 while preventing bubbling problems.

[0055] Based on the above content, after one side of the double-sided tape 1 is bonded to the inner surface of the outer layer fabric 2, a dividing line 12 is laser-formed on the other side of the double-sided tape 1 along a direction parallel to the edge of the outer layer fabric 2 for sewing the outer seam line 5 of the loose-leaf, and the distance between the dividing line 12 and the edge of the outer layer fabric 2 for sewing the outer seam line 5 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 tape 1 into a first film paper 13 and a second film paper 14, wherein the first film paper 13 is located on the side of the dividing line 12 away from the edge of the outer layer fabric 2 for sewing the outer seam line 5 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, and the second film paper 14 is located on the side of the dividing line 12 close to the edge of the outer layer fabric 2 for sewing the outer seam line 5 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.

[0056] Afterwards, tear off the first film paper 13, and adhere the bile cloth 3 to the side of the dividing line 12 away from the edge of the outer layer fabric 2 for sewing the outer seam line 5 of the loose-leaf, that is, after tearing off the first film paper 13, adhere the bile cloth 3 to the exposed sticky area on the double-sided tape 1, and the outer edge of the bile cloth 3 is aligned with the dividing line 12, that is, the fifth edge 31 is aligned with the dividing line 12, and the cutting line can also provide a reference for the alignment of the bile cloth 3, thereby making the operation easier.

[0057] Moreover, it is worth mentioning that in the present 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 bile cloth 3, and the inner edge of the inner layer fabric 4 and the inner edge of the bile cloth 3 are respectively the sixth edge 42 and the seventh edge 32. In the present embodiment, when covering the inner layer fabric 4, the sixth edge 42 and the seventh edge 32 are aligned. Therefore, the present embodiment can accurately determine the size of the bile cloth 3 according to the position of the dividing line 12 and the size of the inner layer fabric 3.

[0058] In addition, based on the above, after sewing the outer edge of the inner layer fabric 4 with the edge of the outer layer fabric 2 used for sewing the outer seam 5 of the loose-leaf, that is, after sewing the fourth edge 41 and the second edge 21, tear off the second film paper 14, and then bond the inner layer fabric 4 to the double-sided tape 1 to avoid the inner layer fabric 4 from bonding to the double-sided tape 1 during the sewing process, thereby preventing the bonding position of the inner layer fabric 4 from being wrong.

[0059] Furthermore, it is worth noting that in this embodiment, the inner layer fabric 4 is bonded to the double-sided adhesive tape 1 by means of a pressing machine, thereby ensuring that the inner layer fabric 4 and the double-sided adhesive tape 1 are firmly bonded.

[0060] Similarly, in this embodiment, the outer layer fabric 2 and the double-sided adhesive tape 1 are bonded by a pressing machine, thereby ensuring that the outer layer fabric 2 and the double-sided adhesive tape 1 are firmly bonded.

[0061] Similarly, in this embodiment, the bile cloth 3 and the double-sided adhesive tape 1 are bonded by a pressing machine, thereby ensuring that the bile cloth 3 and the double-sided adhesive tape 1 are firmly bonded.

[0062] Furthermore, in the present embodiment, the portion of the bladder cloth 3 that extends beyond the inner edge of the double-sided tape 1 is sewn together with the inner layer cloth 4 along a direction parallel to the edge of the seam line 5 on the outer layer cloth 2 for sewing the outer opening of the loose-leaf, that is, in the present embodiment, the fixed seam line 43 between the inner layer cloth 4 and the bladder cloth 3 extends along a direction parallel to the second edge 21. Therefore, the present embodiment can more conveniently determine the seams of the inner layer cloth 4 and the bladder cloth 3, thereby further simplifying the operation.

[0063] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
