Processing method of seamless loose-leaf

Abstract

The present invention belongs to the field of clothing production technology and discloses a seamless loose-leaf processing method. The present invention adheres a layer of lining cloth to the inner surface of the outer layer cloth. The lining cloth provides a sewing position for the inner layer cloth, so that the inner layer cloth is sewn to the side of the lining cloth facing away from the outer layer cloth, thereby fixing the side of the outer layer cloth facing the inner layer cloth and the side of the inner layer cloth facing the outer layer cloth. When the user wears the clothing, if the outer layer cloth is pulled, the inner layer cloth can be pulled along with the outer layer cloth, thereby preventing the inner layer cloth from being exposed, thereby avoiding affecting the wearing effect. Moreover, in the present invention, only one side of the double-sided tape is completely adhered to the outer layer cloth, thereby preventing the problem of bubbling in the clothing. In addition, since the lining cloth does not need to extend to the front center line, its size is easier to control, thereby avoiding the problem of arching and unevenness on the clothing. At the same time, the present invention can reduce the number of stitches and simplify the alignment operation, thereby reducing the difficulty of operation.

Description

Technical Field

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

[0002] In the existing technology, some styles of clothing need to be processed with seamless loose-leafs during the production process, where the loose-leafs refer to the movable parts of the clothing such as pockets and lapels. The outer surface of the seamless loose-leafs 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 sewing, which causes the inner layer fabric to be easily exposed due to the outer layer fabric being pulled when the user wears the clothing, thereby affecting the wearing effect.

[0003] Therefore, in order to ensure the wearing effect, the prior art generally adopts a method of sewing a tie strip on 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 of 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 on the edge of the outer layer of fabric and the inner layer of fabric. 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] As for the method of directly bonding the outer layer fabric and the inner layer fabric with 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 seams 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 bonding operations 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 can easily cause bubbling problems on the loose-leaf, thereby affecting the wearing effect. Summary of the Invention

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

DETAILED DESCRIPTION

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0036] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components.

[0037] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0038] In the description of this embodiment, terms such as "upper," "lower," "right," and "left" are used to refer to positions or locations based on those shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes 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 existing technology generally adopts a method of adding a sew strip to the inner layer fabric of the seamless loose-leaf or directly gluing the outer layer fabric of the seamless loose-leaf and the inner layer fabric 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 bar 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 5 for sewing the outer edge 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 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 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 5 of the outer edge 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 without seamless loose-leafs by using 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 for sewing the outer seam of the loose-leaf is aligned with the outer edge of the inner layer fabric 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 in the loose-leaf, thereby affecting the wearing effect.

[0042] To resolve the above issues, please refer to Figures 2 to 7 , and combined with Figure 1 This embodiment provides a method for processing a sutureless 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 seam 5 on the outer layer fabric 2 for sewing the outer edge 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 edge of the loose-leaf 5 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, a lining cloth 3 is adhered to the other side of the double-sided tape 1. The lining cloth 3 covers the inner edge of the double-sided tape 1. The inner edge of the double-sided tape 1 is described as the third edge 16. The third edge 16 is opposite to the first edge 15. 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. 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 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. Afterwards, after the outer fabric and the inner 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 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 first bonded to the inner surface of the outer layer cloth 2, and then the inner layer cloth 4 is sewn to 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 clothes, 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 not just the side of the inner layer cloth 4 close to the outer opening seam 5 of the loose-leaf is pulled, thereby preventing the inner layer cloth 4 from being exposed, thereby avoiding affecting the wearing effect. Moreover, the bile 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 fabric 4. At the same time, this embodiment only needs to sew a seam on the bile cloth 3, thereby reducing the time for sewing and alignment. In addition, this embodiment only aligns the double-sided tape 1 and the outer layer fabric 2 in the process of bonding one side of the double-sided tape 1 to the inner surface of the outer layer fabric 2, and there is no need to align the double-sided tape 1 and the inner layer fabric 4 subsequently, thereby reducing the difficulty of operation. Moreover, this embodiment only makes one side of the double-sided tape 1 completely adhere to the outer layer fabric 2, thereby avoiding the problem of bubbling of the loose-leaf.

[0050] That is, this embodiment adheres a layer of bladder cloth 3 to the inner surface of the outer layer fabric 2. The bladder cloth 3 is used to provide a sewing position for the inner layer fabric 4, so that the inner layer fabric 4 is sewn to the side of the bladder cloth 3 facing away from the outer layer fabric 2, 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. 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 as a whole, thereby preventing the inner layer fabric 4 from being exposed, thereby avoiding affecting the wearing effect. Moreover, in this embodiment, only one side of the double-sided tape 1 is completely adhered to the outer layer fabric 2, thereby preventing the garment from bubbling. In addition, since the bladder cloth 3 does not need to extend to the front center line 7, its size is easier to control, thereby avoiding the problem of arching and unevenness on the garment. At the same time, this embodiment can reduce the number of stitches and simplify the alignment operation, thereby reducing the difficulty of operation.

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

[0052] As described above, in this embodiment, the portion of the inner layer fabric 4 near the outer seam 5 of the loose-leaf 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 near the outer seam 5 of the loose-leaf 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 portion of 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 bonds to the double-sided tape 1, bubbling can be avoided.

[0054] For example, 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 part of the inner layer fabric 4 close to the loose-leaf outer seam 5 can be bonded with 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 edge seam 5 of the loose-leaf. The distance between the dividing line 12 and the edge of the outer layer fabric 2 for sewing the outer edge seam 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 edge seam 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 edge seam 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 edge seam 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. 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 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 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 this embodiment, when covering the inner layer fabric 4, the sixth edge 42 and the seventh edge 32 are aligned. From the above, this 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 bile cloth 3.

[0058] In addition, based on the above, after sewing the outer edge of the inner layer fabric 4 to the edge of the outer layer fabric 2 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 being bonded 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] Likewise, in this embodiment, the outer layer fabric 2 and the double-sided adhesive tape 1 are bonded together 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 tape 1 are bonded by a pressing machine, thereby ensuring that the bile cloth 3 and the double-sided tape 1 are firmly bonded.

[0062] Furthermore, in this 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 5 for sewing the outer opening of the loose-leaf on the outer layer cloth 2. That is, in this embodiment, the fixed seam 43 between the inner layer cloth 4 and the bladder cloth 3 extends along a direction parallel to the second edge 21. Therefore, this 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 the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
