Abstract
Description
Multi-layer sleeve structure with sleeve mid-sleeve division and labeling, sewing method, and down jacket Technical Field
[0001] The present invention relates to a sleeve structure, a sewing method and a down jacket, and in particular to a multi-layer sleeve structure with a sleeve divided and marked, a sewing method and a down jacket. Background Art
[0002] In the production process of down jackets, it is common to encounter styles with raglan sleeves that have splits and tangents that require armbands. The existing technology is to sew two layers of lining cloth together and then connect them to the fabric, and then sew the quilting line. When the fabric needs to be sewn with an armband (usually set at the upper arm position), the two layers of lining cloth will be directly sewn through. Therefore, the stitching along the edge of the armband connects the fabric under the armband and the two layers of lining cloth to form an independent area. The space between the two layers of lining cloth under the armband is not connected to the space between the two layers of lining cloth in other parts, resulting in a down-free area at the upper arm. The warmth retention of this position is poor, and there will be a noticeable depression at the armband after filling, resulting in a poor appearance.
[0003] Summary of the Invention
[0004] To address the above technical needs, the present invention provides a multi-layer sleeve structure with a mid-sleeve split and sewn label. This ensures full down filling throughout the sleeve, preventing poor warmth retention due to insufficient down filling at the sleeve label. The present invention also provides a method for sewing a multi-layer sleeve structure with a mid-sleeve split and sewn label. This method changes the sewing order of each component and avoids conflicts between quilting and sewing without compromising production efficiency. The present invention also provides a down jacket.
[0005] The technical solution of the present invention is as follows: A multi-layer sleeve structure with a sleeve divided and labeled in the middle, comprising a sleeve badge, a fabric, a first liner cloth and a second liner cloth stacked in sequence from the outside to the inside, the fabric comprising a front sleeve fabric and a back sleeve fabric, the first liner cloth comprising a front sleeve first liner cloth and a back sleeve first liner cloth, the front sleeve fabric, the back sleeve fabric, the front sleeve first liner cloth and the back sleeve first liner cloth are sewn together at the sleeve middle seam, the sleeve badge is sewn across the sleeve middle seam to the outside of the fabric, the stitching of the sleeve badge passes through the fabric and the first liner cloth, the quilting line arranged crosswise with the sleeve middle seam passes through the fabric, the first liner cloth and the second liner cloth, the quilting line passing through the sleeve badge is sewn around the sleeve badge along a partial outline of the sleeve badge.
[0006] Furthermore, the sleeve center seam is provided with a first stitch and a second stitch, the first stitch runs through the front sleeve fabric and the first lining cloth of the front sleeve, and the second stitch runs through the front sleeve fabric, the back sleeve fabric, the first lining cloth of the front sleeve and the first lining cloth of the back sleeve.
[0007] Furthermore, the first suture and the second suture are on the same path.
[0008] Furthermore, a binding structure is provided on the inner side of the first lining fabric of the front sleeve and the first lining fabric of the back sleeve at the center seam of the sleeve. The binding structure formed on the first lining fabric of the front sleeve and the first lining fabric of the back sleeve can prevent lint from penetrating the center seam of the sleeve.
[0009] Furthermore, it includes a lining, and the lining is arranged on the inner side of the second lining cloth.
[0010] Another technical solution of the present invention is as follows: a method for sewing a multi-layer sleeve structure with a sleeve mid-sleeve segmentation and marking, comprising the following steps:
[0011] Step 1: Align the front sleeve fabric and the first lining of the front sleeve and sew them together at the center seam of the sleeve with the first seam;
[0012] Step 2: Align the back sleeve fabric and the first lining of the back sleeve at the center seam of the sleeve and assemble the front sleeve fabric and the first lining of the front sleeve sewn in step 1 with the second stitching line;
[0013] Step 3: Sew the armband across the center seam of the sleeve on the outside of the fabric, with the stitching of the armband passing through the fabric and the first lining cloth;
[0014] Step 4: Collect the second bile cloth;
[0015] Step 5: Quilting the fabric, the first liner cloth and the second liner cloth with a quilting line, wherein the quilting line is arranged to cross the center seam of the sleeve, and the quilting line passing through the armband is sewn around the armband along a partial outline of the armband.
[0016] Furthermore, step 2A is included between step 2 and step 3, in which the front sleeve fabric, the front sleeve first lining cloth, the back sleeve fabric and the back sleeve first lining cloth are hemmed on the inner sides of the front sleeve first lining cloth and the back sleeve first lining cloth at the center seam of the sleeve.
[0017] Furthermore, step 2B is included between step 2A and step 3, which is to tangent-sew the back sleeve fabric at the center seam of the sleeve.
[0018] Furthermore, the first suture and the second suture are sewn along the same path.
[0019] Another technical solution of the present invention is: a down jacket having the aforementioned multi-layer sleeve structure with the sleeves divided and marked, and the first lining cloth and the second lining cloth are filled with down.
[0020] The advantages of the present invention compared with the prior art are:
[0021] The single piece of first liner cloth in the prior art is broken into the first liner cloth for the front sleeve and the first liner cloth for the back sleeve, which can save a first liner cloth, reduce the number of working steps, save costs, and meet the requirements of mass production.
[0022] The first gussets of the front sleeve and the back sleeve are first sewn to the fabric (front sleeve fabric and back sleeve fabric), so that the structure has a four-layer fabric (including lining) structure but achieves the effect of a three-layer structure. The connection between the first gussets and the fabric makes the appearance more fit, improving the appearance of the sleeves.
[0023] Sewing the armband first and then quilting can avoid conflicts between the labeling and quilting paths. The quilting can bypass the armband setting, ensuring sufficient down filling under the armband and ensuring the warmth retention of the sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention will be further described below with reference to the examples, but are not intended to limit the present invention.
[0029] 1 to 4 , the embodiment of the present invention relates to a method for sewing a multi-layer sleeve structure with a sleeve mid-sleeve segmentation and labeling, comprising the following steps:
[0030] Step 1: Align the front sleeve fabric 1 and the first front sleeve lining 2 and sew them up and down at the center seam 3 of the sleeve with a first stitching line 4, wherein the first stitching line 4 passes through the front sleeve fabric 1 and the first front sleeve lining 2.
[0031] Step 2: Align the back sleeve fabric 5 and the back sleeve first lining 6 at the sleeve center seam 3 and sew them vertically and horizontally with a second stitch 7. Simultaneously, the front sleeve fabric 1 and the front sleeve first lining 2 sewn together in step 1 are joined horizontally and horizontally with the second stitch 7. The front sleeve first lining 2 and the back sleeve first lining 6 are two separately cut pieces of fabric, which changes the prior art practice of using a single piece of fabric to form the first lining. This eliminates the step of dart-ing the first lining at the shoulder, thus saving steps. It should also be pointed out that in the description of this step, although the connection process is expressed as "sewing up and down" and "joining left and right", in actual operation, two connections are completed by sewing one seam at a time, that is, the back sleeve fabric 5 and the back sleeve first bladder cloth 6 are superimposed on the front sleeve fabric 1 and the front sleeve first bladder cloth 2 sewn in step 1, and the order of the front sleeve first bladder cloth 2, the front sleeve fabric 1, the back sleeve fabric 5 and the back sleeve first bladder cloth 6 are formed from bottom to top, and the appearance surface of the front sleeve fabric 1 is opposite to the appearance surface of the back sleeve fabric 5, and then the second seam 7 is sewn along the path of the first seam 4 in step 1, thereby completing the sewing of this step.
[0032] Step 2A: Overlock the front sleeve fabric 1, the front sleeve first lining fabric 2, the back sleeve fabric 5, and the back sleeve first lining fabric 6 on the inner sides of the front sleeve first lining fabric 2 and the back sleeve first lining fabric 6 at the sleeve center seam 3. After overlocking, the front sleeve first lining fabric 2 and the back sleeve first lining fabric 6 are tightly fitted to prevent lint from seeping through.
[0033] Step 2B: Sew a cut line 8 on the back sleeve fabric 5 at the center seam 3 of the sleeve, and the cut line 8 is about 0.6 cm away from the center seam 3 of the sleeve.
[0034] Step 3: Sew the armband 9 across the center sleeve seam 3 to the outside of the fabric. In this embodiment, the circular armband 9 is positioned halfway on the front sleeve fabric 1 and the other half on the back sleeve fabric 5. Connect the armband 9 to the fabric and the first lining along its outer circumference, i.e., the stitching of the armband 9 penetrates the fabric and the first lining.
[0035] Step 4: sew the dart 11 at the shoulder of the second bladder cloth 10.
[0036] Step 5: Align the already sewn fabric, the first gusset, and the darted second gusset 10. Quilting thread 12 is then woven through the fabric, the first gusset, and the second gusset 10. Quilting thread 12 is intersected with the center sleeve seam 3. The quilting thread 12, which passes through the armband 9, is then sewn around the armband 9 along a portion of its contour. In this embodiment, the quilting thread 12 is perpendicular to the center sleeve seam 3 and formed in a semicircular pattern around the armband 9, completing the sewing of the main structure.
[0037] Step 6. After the quilting line 12 is sewn, several filling channels 13 are formed between the first lining cloth and the second lining cloth 10. One end of the filling channel 13 is sewn closed and then filled with down. Then, the lining 14 is used to connect the front sleeve and the back sleeve on the other side to complete the production of the down jacket sleeve. Then, it is assembled with the down jacket body to make the down jacket.
[0038] The multi-layer sleeve structure, obtained by the above-described sewing method, is shown in Figure 2. It comprises, from the outside in, an armband 9, fabric, a first lining, a second lining 10, and a lining 14, stacked in order. The fabric is composed of front sleeve fabric 1 and back sleeve fabric 5, and the first lining is composed of front sleeve first lining 2 and back sleeve first lining 6. The front sleeve fabric 1, back sleeve fabric 5, front sleeve first lining 2, and back sleeve first lining 6 are sewn together at the sleeve center seam 3, forming a single, two-layer structure. Two stitches, a first stitch 4 and a second stitch 7, are located at the center seam 3. The first stitch 4 and the second stitch 7 follow the same path. The first stitch 4 passes through the front sleeve fabric 1 and the front sleeve first lining 2, as shown in Figure 3. The second stitch 7 passes through the front sleeve fabric 1, the back sleeve fabric 5, the front sleeve first lining 2, and the back sleeve first lining 6, as shown in Figure 4. The armband 9 is sewn to the outside of the fabric across the sleeve center seam 3, with the stitching of the armband 9 passing through the fabric and the first lining. A quilting thread 12, intersecting the center sleeve seam 3, penetrates the fabric, the first and second lining fabrics 10 to form multiple filling channels 13. In this embodiment, the quilting thread 12 is perpendicular to the center sleeve seam 3. When the quilting thread 12 encounters the armband 9, it is sewn around the armband 9 along the partial contour of the armband 9 to avoid the armband 9.
[0039] The multi-layer sleeve structure and sewing method with the sleeves divided and marked in the above embodiment break the original whole piece of first liner cloth, which can save a dart 11 and reduce the number of steps. Sewing together with the fabric changes its internal structure. The four-layer structure achieves the effect of a three-layer structure, making the sleeves more fitting in appearance and avoiding the lack of velvet on the sleeves at the position of the armband 9, thus meeting the warmth retention requirements.
