Description

Technical Field

[0001] This invention relates to the field of clothing manufacturing technology, specifically a process for smoothing and recessing the corners of a neckline. Background Technology

[0002] Formal attire refers to formal clothing suitable for serious occasions; it is not for entertainment or casual settings. Examples include suits and Zhongshan suits. Suits generally have a collar structure, and there are generally three types of suit collars: shawl collar, peak lapel, and notched lapel.

[0003] Peak lapels typically have a corner structure. During the production of peak lapels, because it's necessary to create a corner collar, such as... Figure 2 As shown at point A, multiple cuts are often required, which places high demands on the sewing operation and the operator's skills. Making slightly more or fewer cuts will directly affect the flatness and appearance of the suit collar.

[0004] Traditional manufacturing processes require cutting edges, which easily leads to unevenness, wrinkles, dents, and pits. This severely tests the maker's skill level. Improper operation will directly affect the flatness and appearance of the suit collar. If the flatness and appearance of the suit collar are poor, it will fail the factory inspection and require rework. This not only wastes fabric but also reduces production efficiency and is not conducive to practical application and operation.

[0005] Therefore, those skilled in the art provide a process for smoothing the concave corner of a neckline to solve the problems mentioned in the background art. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a process for smoothing the concave corners of the collar, which solves the problem mentioned in the background art where the flatness and appearance of suit collars are poor due to insufficient craftsmanship by the maker, requiring rework.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a process for smoothing the concave corner of a neckline, comprising the following steps: S1. Prepare materials: Select the main collar fabric, collar loop fabric, PVC coating, and a threader; S2. Measure and draw the size of the neckline, and cut the neckline fabric according to the drawn lines; S3. Leave seam allowance at both ends of the collar fabric for later corner finishing, and align the other two ends of the collar fabric. S4. Slip the collar over the neckline, adjust the position of the overlapping part of the two collars, and secure them in place. S5. Fold the excess fabric inwards and secure it at the corner of the neckline; S6. Sew the corner folds of the collar together; S7. At the corner, use glue to bond two pieces of cotton fabric to the two layers of fabric respectively, thereby filling the depression at the corner and achieving a smooth effect. S8. After the corners are sewn, use adhesive tape to fully glue and fix the collar to the inside of the neckline. S9. At the outer stitches of the right collar piece, fold the two ends of the collar loop inward and cover them with a sewing. At the same time, fold the left collar loop over the right collar loop to make it fit tightly against the right collar loop and sew the collar loop together. S10. Iron it.

[0008] By using the above technical solution, in step S7, two pieces of cotton fabric are glued to the two layers of fabric at the corner, thereby flattening the corner and filling the depression at the corner, ensuring the flatness and appearance of the suit collar.

[0009] Preferably, the collar fabric in step S1 is a double-layered fabric, which includes an outer layer and an inner layer. The outer layer is made of nylon or polyester, and the inner layer is made of cotton fabric.

[0010] Through the above technical solutions, nylon or polyester fabrics with good abrasion resistance and elasticity are used to ensure the durability of the collar, while cotton fabrics are soft and breathable to improve the comfort of the collar.

[0011] Preferably, the neckline drawn in step S2 is larger than the neckline circumference, and the outer and inner layers of fabric must be kept in the same size and shape when cutting the neckline fabric in step S2.

[0012] The above technical solutions ensure the flatness of the sewn collar.

[0013] Preferably, in step S3, the seam allowance at each end of the collar fabric is 1-2 cm. After aligning the other two ends of the collar fabric in step S3, the inner pleats need to be fixed with needle and thread.

[0014] The above technical solution utilizes the seam allowance for later corner treatment.

[0015] Preferably, during the fixing and positioning process in step S4, the upper and lower ends of the collar should be aligned with the center line of the neckline.

[0016] By using the above technical solution, the top and bottom ends of the collar should be aligned with the center line of the neckline, thereby ensuring more accurate subsequent processing of the collar.

[0017] Preferably, in step S5, after the excess fabric is folded inward and fixed, a small slit needs to be cut diagonally at the folded corner.

[0018] The above technical solution involves making a small diagonal cut at the corner to reduce the thickness.

[0019] Preferably, in step S6, the corner folds of the collar are sewn using a triangular stitch. The specific steps of the triangular stitch are as follows: S61. Fold the fabric at the corner fold to create a short edge, and sew from left to right. The first stitch goes from the leftmost inside side forward through the front fabric and pulls it out. S62. The second stitch lands on the upper right side. The needle is passed from front to back and pulled out. At the same time, the position of the second stitch is 6mm away from the first stitch. S63. The third stitch falls at the lower right position, parallel to the first stitch. It is threaded from back to front and pulled out. At the same time, the third stitch is 6mm away from the second stitch. S64. The fourth stitch falls on the upper left, intersecting the line connecting the first and second stitches, and is parallel to the second stitch. At this point, a triangle is sewn. S65. The fifth stitch falls to the left of the thread connecting the third and fourth stitches, crossing it. Then repeat steps S62, S63 and S64 until the required length is sewn.

[0020] The above technical solution reduces the thickness at the corners, making it fit the neckline better.

[0021] Preferably, in step S8, before fully bonding and fixing the collar to the inside of the neckline with adhesive, it is necessary to check whether the collar can be smoothly inserted into the neckline. If it can be smoothly inserted, the subsequent operation steps can be continued. If it cannot be smoothly inserted, step S5 above needs to be repeated to change the position of the corner fold.

[0022] The above technical solution ensures that the collar can be smoothly fitted into the neckline, thereby guaranteeing the accuracy of the collar size.

[0023] Preferably, a sewing machine is used to perform the covering stitch and collar stitching in step S9.

[0024] The above technical solutions facilitate better sewing operations using sewing machines, thereby improving sewing efficiency and benefiting practical applications and operations.

[0025] Preferably, the ironing temperature in step S10 is 100℃-120℃, and the time is 10min-15min.

[0026] By using the above technical solutions and ironing, the collar can be made flatter, improving its texture and appearance. At the same time, during the ironing process, attention should be paid to the control of temperature and time to avoid scorching or deformation of the collar.

[0027] This invention provides a process for smoothing the concave corner of a neckline, which has the following beneficial effects: This neckline corner smoothing process involves using glue to bond two pieces of cotton fabric to the upper and lower fabrics at the intersection of the collar's notch and the undercollar notch, where the angle turns. This fills in the notch and achieves a smooth finish, preventing situations where poor collar smoothness or appearance leads to failure to pass factory quality checks and requiring rework. This process not only saves fabric but also improves production efficiency, making it beneficial for practical application and operation. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Example

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This invention provides a process for smoothing the concave corner of a neckline, comprising the following steps: S1. Prepare materials: Select the main collar fabric, collar loop fabric, PVC coating, and threader. The collar loop fabric is a double-layered fabric, consisting of an outer layer and an inner layer. The outer layer is made of nylon or polyester, which are fabrics with good abrasion resistance and elasticity to ensure the durability of the collar. The inner layer is made of cotton fabric, which is soft and breathable to improve the comfort of the collar. S2. Measure and draw the size of the neckline. The drawn neckline should be larger than the circumference of the neck. Cut the neckline fabric according to the drawn lines. When cutting the neckline fabric, the size and shape of the outer and inner layers of fabric should be consistent to ensure the flatness of the neckline after sewing. S3. Leave a 2cm seam allowance at each end of the collar fabric for later corner finishing. Align the other two ends of the collar fabric and secure the inner pleats with needle and thread. S4. Slip the collar over the neckline, adjust the position of the overlapping part of the two collars, and make sure that the top and bottom ends of the collar are aligned with the center line of the neckline and fix them in place. S5. Fold the excess fabric inward at the corner of the neckline and secure it, and make a small diagonal cut at the corner to reduce the thickness. S6. Use the triangular stitch method to sew the corner folds of the neckline, reducing the thickness at the corners and making it fit the neckline better. The specific steps for using the triangular stitch method are as follows: S61. Fold the fabric at the corner fold to create a short edge, and sew from left to right. The first stitch goes from the leftmost inside side forward through the front fabric and pulls it out. S62. The second stitch lands on the upper right side. The needle is passed from front to back and pulled out. At the same time, the position of the second stitch is 6mm away from the first stitch. S63. The third stitch falls at the lower right position, parallel to the first stitch. It is threaded from back to front and pulled out. At the same time, the third stitch is 6mm away from the second stitch. S64. The fourth stitch falls on the upper left, intersecting the line connecting the first and second stitches, and is parallel to the second stitch. At this point, a triangle is sewn. S65. The fifth stitch falls to the left of the thread connecting the third and fourth stitches, crossing it. Then repeat steps S62, S63 and S64 until the required length is sewn. S7. At the corner, use glue to bond two pieces of cotton fabric to the two layers of fabric respectively, thereby filling the depression at the corner and achieving a smooth effect. Figure 3 As shown at point B in the middle; S8. After the corner is sewn, check if the collar can be smoothly put into the neckline. If it can be smoothly put into the neckline, you can continue with the next steps. If it cannot be smoothly put into the neckline, you need to repeat step S5 above, change the position of the corner fold, and then use adhesive to fully glue and fix the collar to the inside of the neckline. S9. At the outer stitches of the right collar piece, fold the two ends of the collar loop inward and sew them together using a sewing machine. At the same time, fold the left collar loop over the right collar loop to make it fit tightly against the right collar loop, and sew the collar loop together using a sewing machine. S10. Iron the collar at 110℃ for 13 minutes. Ironing will make the collar smoother and improve its texture and appearance. During the ironing process, it is important to control the temperature and time to avoid scorching or deformation of the collar.

[0032] The collars made are like Figure 4 As shown at point C.

[0033] Comparative Example Includes the following steps: S1. Prepare materials: Select the main collar fabric, collar loop fabric, PVC coating and threader. The collar loop fabric is a double-layered fabric, which includes an outer layer and an inner layer. The outer layer is made of nylon or polyester, and the inner layer is made of cotton fabric. S2. Measure and draw the size of the neckline. The drawn neckline should be larger than the circumference of the neck. Cut the neckline fabric according to the drawn lines. When cutting the neckline fabric, the size and shape of the outer and inner layers of fabric should be consistent to ensure the flatness of the neckline after sewing. S3. Leave a 2cm seam allowance at each end of the collar fabric for later corner finishing. Align the other two ends of the collar fabric and secure the inner pleats with needle and thread. S4. Slip the collar over the neckline, adjust the position of the overlapping part of the two collars, and make sure that the top and bottom ends of the collar are aligned with the center line of the neckline and fix them in place. S5. Fold the excess fabric inward at the corner of the neckline and secure it, and make a small diagonal cut at the corner to reduce the thickness. S6. Use the triangular stitch method to sew the corner folds of the neckline, reducing the thickness at the corners and making it fit the neckline better. The specific steps for using the triangular stitch method are as follows: S61. Fold the fabric at the corner fold to create a short edge, and sew from left to right. The first stitch goes from the leftmost inside side forward through the front fabric and pulls it out. S62. The second stitch lands on the upper right side. The needle is passed from front to back and pulled out. At the same time, the position of the second stitch is 6mm away from the first stitch. S63. The third stitch falls at the lower right position, parallel to the first stitch. It is threaded from back to front and pulled out. At the same time, the third stitch is 6mm away from the second stitch. S64. The fourth stitch falls on the upper left, intersecting the line connecting the first and second stitches, and is parallel to the second stitch. At this point, a triangle is sewn. S65. The fifth stitch falls to the left of the thread connecting the third and fourth stitches, crossing it. Then repeat steps S62, S63 and S64 until the required length is sewn. S7. After the corner is sewn, check if the collar can be smoothly put into the neckline. If it can be smoothly put into the neckline, you can continue with the next steps. If it cannot be smoothly put into the neckline, you need to repeat step S5 above, change the position of the corner fold, and then use adhesive to fully glue and fix the collar to the inside of the neckline. S8. At the outer stitch of the right collar piece, fold the two ends of the collar loop inward and sew them together with a sewing machine. At the same time, fold the left collar loop over the right collar loop to make it fit tightly against the right collar loop and sew the collar loop together with a sewing machine. S9. Iron the product at a temperature of 110℃ for 13 minutes.

[0034] The collars made are like Figure 4 As shown at point D in the middle.

[0035] The specific operation steps of the embodiment differ from those of the comparative example by one step, S7, which is: "At the angled bend, two pieces of cotton fabric are glued to the two layers of fabric respectively, thereby filling the depression at the corner and achieving a smoothing effect, such as..." Figure 3 As shown at point B in the middle; According to Figure 4 As shown, after comparing the embodiments with the comparative examples, it is not difficult to find that: the collar produced by using the specific steps of the embodiments is as follows...
