Abstract
Description
Technical Field
[0001] This invention relates to the field of clothing technology, and more particularly to a garment and its sewing method. Background Technology
[0002] To conceal raw edges or prevent them from forming on the garment edges, the edges are typically wrapped with binding strips and sewn together. This binding extends the garment's lifespan and improves its quality. Currently, there are two common methods for binding the corners of garments. One method involves using two binding strips 20 to wrap around the two adjacent edges at the corner O of the garment piece 10 and then sewing them together (e.g., ...). Figure 1 As shown in the figure, the overlapping of the binding strips 20 on the two adjacent sides at the corner O results in a thicker corner O of the garment piece 10, which can cause a foreign body sensation for the user and affect the quality of the finished garment. Another binding method is to avoid the fabric being too thick at the corner. First, two binding strips are used to wrap the two adjacent sides of the corner of the garment, and then a stitch is sewn along the two adjacent sides from the end of the binding strip away from the corner to a position a certain distance away from the corner. Then, the binding strip at the corner is cut according to the angle of the corner and the two binding strips are spliced together. Finally, the binding strip at the corner is sewn together. However, this method is difficult to operate, and the sewing threads before and after sewing are difficult to align, which can easily lead to inconsistent binding width and affect the quality of the finished garment. Summary of the Invention

[0031] Secondly, the present invention provides a garment, which is obtained by sewing using the garment sewing method described in the first aspect above.
[0032] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0033] This invention provides a garment and its sewing method. A binding strip has a first fold line and a second fold line intersecting at a first intersection point. The first fold line extends along the width of the binding strip, dividing it into a first part and a second part. By folding the binding strip, the two parts correspond to two adjacent edges at the corner of the garment piece. Before folding the binding strip to cover the raw edge of the garment piece, the first part and the second part are sewn together along the direction from the first fold line to the two opposite sides of the binding strip, forming a first seam and a second seam respectively. Then, the binding strip is cut along the length of the first seam and along the length of the second seam, while retaining the first and second seams to reduce fabric stacking at the corners and avoid excessive local thickness in the finished garment. Finally, the binding strip is folded to cover the first raw edge of the garment piece with the first part and the second raw edge with the second part. The binding strip and the garment piece are then sewn together along the lengths of the first and second raw edges, forming a first topstitch and a second topstitch respectively. In this way, the seams on the garment's edge consist only of a first and a second topstitch, both formed in a single stitch. This results in neat and aesthetically pleasing seams on the garment's surface and improves the consistency of the edge width. In other words, the garment and its sewing method provided by this invention can reduce the thickness at the corners of the garment and improve the consistency of the edge width, thereby enhancing the quality of the finished garment.

[0055] The following will further explain, in conjunction with embodiments and accompanying drawings, how this application solves the technical problems raised in the background art.
[0056] Please refer to the following: Figures 2 to 5 In a first aspect, the present invention provides a garment sewing method, which includes the following steps:
[0057] S1. Provide a garment piece and a binding strip. The corners of the garment piece have adjacent first and second raw edges. The binding strip has a first fold line and a second fold line intersecting at a first intersection point. The second fold line is along the length of the binding strip (e.g., along the length of the binding strip). Figure 4 and Figure 5 The first fold line extends along the width direction of the binding strip (as indicated by the arrow x in the image). Figure 4 and Figure 5 The edging strip is extended in the direction indicated by the arrow y in the diagram to divide the edging strip into a first part and a second part, and to divide the second fold line into a first sub-fold line and a second sub-fold line. The first part has a first side and a second side extending along the length direction of the edging strip, and the second part has a third side and a fourth side extending along the length direction of the edging strip, with the first side and the third side connected, and the second side and the fourth side connected.
[0058] Dividing the binding strip 20 into two parts (i.e., the first part 21 and the second part 22) along the first fold line 201 facilitates binding the two sides of the garment piece 10.
[0059] Optionally, the thickness of the binding strip 20 is less than the thickness of the garment piece 10, so that the thickness of the edge of the garment 100 after binding (i.e., the sum of the thicknesses of the binding strip 20 and the garment piece 10) is as small as possible, thereby reducing the thickness difference between the edge of the garment 100 and the garment piece 10, which is beneficial to improving the quality of the garment 100 and avoiding the user's feeling of foreign objects when wearing it.
[0060] Optionally, the binding strip 20 can be made of lining or pure cotton to make the binding strip 20 thinner, so that the thickness of the edge of the garment 100 after binding is less different from the thickness of the garment piece 10, thereby improving the quality of the garment 100.
[0061] Optionally, considering that when binding the edge of garment piece 10, to prevent the edge yarn of the binding strip 20 from becoming loose, the binding strip 20 is usually folded in half to wrap around the edge of garment piece 10, and the binding strips 20 on both sides of garment piece 10 are folded towards garment piece 10 to wrap the edge of the binding strip 20 inside. Based on this, the width of the binding strip 20 is 2 to 4 times greater than the seam width of garment piece 10 (i.e., the distance from the sewing thread used to sew the edge of garment piece 10 to the edge of garment piece 10). For example, if the seam width of garment piece 10 is 1cm, the width of the binding strip 20 can be 2cm, 2.5cm, 3cm, or 4cm, etc., so that the binding strip 20 has enough slack when binding the edge of garment piece 10 to fold the edge of the binding strip 20 inside, avoiding the situation where the edge yarn of the binding strip 20 becomes loose, and also avoiding the situation where the width of the binding strip 20 is too large. When the width of the binding strip 20 is too large, to ensure that the binding width matches the seam width, the binding strip 20 is often folded in half to wrap the garment piece 10, and then the edge of the binding strip 20 is folded along the seam width until the excess is completely wrapped inside. This results in the binding strip 20 piling up, leading to excessive binding thickness. Alternatively, to avoid excessive thickness in some areas of the garment 100, the binding strip 20 is often folded in half to wrap the garment piece 10, and then the two parts of the binding strip 20 separated by the garment piece 10 are... Fold the binding strip 20 in half along the direction towards the garment piece 10, that is, fold the first side 211 and the second side 212 of the binding strip 20 inwards so that the first side 211 and the second side 212 are set to correspond to the first raw edge 11 and the first side 211 and the second side 212 are wrapped inside. In this way, the width of the binding strip 20 wrapped around the garment piece 10 (i.e. the binding width) is greater than the seam width. The distance between the sewing thread of the seam and the edge of the binding is too large, which can easily lead to the problem of the binding edge curling up or folding.
[0062] To facilitate understanding, examples of different binding strip widths 20 are provided. It should be noted that the binding methods in the examples are for illustrative purposes only and are not part of the sewing method of the garment 100 in this embodiment.
[0063] In one example, the seam width of garment piece 10 is 1cm, and the width of binding strip 20 is 2.5cm. When binding the first raw edge 11 of garment piece 10, the binding strip 20 can be folded along the second fold line 202 and wrapped around the first raw edge 11. Then, the binding strip 20 can be folded towards the garment piece 10 along its corresponding seam line so that the width of the binding strip 20 wrapped around the garment piece 10 (i.e., the binding width) is 1cm. The edges of the binding strip 20 are each wrapped with a 0.25cm seam allowance to avoid the phenomenon of raw edges on the edges of the binding strip 20.
[0064] In another example, the seam width of garment piece 10 is 1cm, and the width of binding strip 20 is 4cm. When binding the first raw edge 11 of garment piece 10, the binding strip 20 can be folded along the second fold line 202 and wrapped around the first raw edge 11. Then, the two parts of binding strip 20 separated by garment piece 10 are folded in the direction towards garment piece 10. That is, the first side 211 and the second side 212 of binding strip 20 are folded inwards until the first side 211 and the second side 212 correspond to the first raw edge 11, and the first side 211 and the second side 212 are wrapped inside. At this time, since the binding strip 20 has been folded twice, the width of the binding strip 20 wrapping the garment piece 10 is 1cm, that is, the binding width is 1cm, which is consistent with or approximately the same as the seam width of garment piece 10. Moreover, the thickness of the binding of garment 100 is uniform, which is beneficial to improving the quality of garment 100.
[0065] This embodiment uses a seam width of 1cm for garment piece 10 and a binding strip width of 4cm as an example for explanation.
[0066] Optionally, considering that the fabric of garment 100 is relatively soft, the first fold line 201 and the second fold line 202 on the binding strip 20 are prone to bending or becoming misaligned after multiple folds. Therefore, in order to improve the accuracy of positioning during the sewing process and avoid positional deviations during sewing or folding, the binding strip 20 is laid flat, and the positions of the first fold line 201 and the second fold line 202 are folded and ironed to make the positions of the first fold line 201 and the second fold line 202 more obvious, which is beneficial to finding the first fold line 201 and the second fold line 202 during the sewing process.
[0067] Understandably, in some other embodiments, considering that the binding strip 20 has a first front and a first back, after binding the garment piece 10, the back of the binding strip 20 faces the garment piece 10, that is, the back of the binding strip 20 will not be exposed on the surface of the finished garment 100. Based on this, materials such as chalk (made of limestone or plaster), crayons or heat-erasable pens, which will disappear or be difficult to detect when the garment 100 is finished, can be used to draw lines along the first fold line 201 and the second fold line 202 on the back of the binding strip 20, so as to facilitate the positioning of the first fold line 201 and the second fold line 202 during the sewing process.
[0068] S2. Divide the binding strip into four equal parts along the width direction, and fold and iron them to form a first fold, a second fold, and a third fold arranged at intervals along the direction from the first side to the second side. The second fold is located on the second fold line, and the first fold line divides the first fold into a first sub-fold and a second sub-fold.
[0069] In this way, folding and ironing the binding strip 20 before sewing it onto the garment piece 10 helps improve the positioning accuracy in the subsequent sewing steps. At the same time, dividing the binding strip 20 into four equal parts helps improve the consistency of the binding width and makes the binding thickness of the garment 100 uniform, thereby improving the finished quality of the garment 100.
[0070] Understandably, in other embodiments, three lines can be drawn evenly and at intervals along the length of the binding strip 20 on the reverse side to divide the binding strip 20 into four equal parts along its width. This not only facilitates the positioning of the binding strip 20 but also eliminates the need for folding and ironing the binding strip 20, thus simplifying the operation steps.
[0071] Optionally, as mentioned above, the width of the binding strip 20 is 4cm. Therefore, after dividing the binding strip 20 into four equal parts along its own width direction, the distance from the first side 211, the second side 212 to the second folded edge 204 is 2cm, and the distance from the first folded edge 203, the third folded edge 205 to the second folded edge 204 is 1cm.
[0072] Please combine Figure 3 and Figure 6 In some embodiments, to facilitate accurate positioning during the sewing process, the binding strip 20 can be marked in advance. Based on this, the angle of the corner O of the garment piece 10 (i.e., the angle between the first raw edge 11 and the second raw edge 12) is defined as θ. A first marking line 206 is formed by drawing a line from the first side 211 to the fourth side 222, and a second marking line 207 is formed by drawing a line from the second side 212 to the third side 221. The first marking line 206 and the second marking line 207 form a first angle α with the second fold line 202 and pass through the first intersection point p. Angle α = θ / 2. The first marking line 206 intersects the first sub-fold 2031 and the third fold 205 at the first endpoint a and the second endpoint b, respectively. The second marking line 207 intersects the second sub-fold 2032 and the third fold 205 at the third endpoint c and the fourth endpoint d, respectively. The first marking line 206, the second marking line 207, the second side 212 and the fourth side 222 enclose a first marking area 20a of a triangle. The first marking line 206, the second marking line 207, the first side 211 and the third side 221 enclose a second marking area 20b of a triangle.
[0073] S3. Place the binding strip 20 on the garment piece 10, and align the first side edge 211 with the first raw edge 11, and align the first fold line 201 with the second raw edge 12 (see [link]). Figure 7 ).
[0074] In this way, the first side 211 is set to correspond with the first raw edge 11, which is conducive to selecting a suitable position to sew the first part 21 and the garment piece 10, so as to reasonably control the seam width of the first side 211 and the second raw edge 12. At the same time, the first fold line 201 is set to correspond with the second raw edge 12, so that the first part 21 of the binding strip 20 is located on the garment piece 10, which is conducive to the first part 21 binding the first raw edge 11.
[0075] Optionally, the garment piece 10 is defined to have a second front and a second back, the second front of the garment piece 10 being the front of the finished garment 100, and the second back of the garment piece 10 being the back of the finished garment 100. The first front of the binding strip 20 is placed facing the second front of the garment piece 10, and the first side 211 is aligned with the first raw edge 11, so that after the binding strip 20 is folded, its first back wraps around the first raw edge 11, and the first front of the binding strip 20 is aligned with the front of the finished garment 100.
[0076] S4. Along the length of the first raw edge 11, the first part 21 is sewn to the garment piece 10 to form a first hidden line 213, and the first hidden line 213 is at a first distance t1 from the second raw edge 12.
[0077] By setting the first concealed thread 213, the binding strip 20 can be sewn and fixed to the garment piece 10, which is beneficial for the folding and positioning of the binding strip 20 in subsequent sewing steps, making the shape of the binding strip 20 neater and improving the quality of the binding of the garment 100. At the same time, considering that the garment piece 10 will be cut in subsequent sewing steps, by limiting the first distance t1, the first concealed thread 213 can be prevented from being cut, thus avoiding the loosening of the sewing thread, improving structural stability, and reducing sewing thread waste.
[0078] Optionally, the first concealed line 213 is located between the first sub-fold 2031 and the first side 211, so that the first part 21 can be fixed together with the garment piece 10 without affecting the folding of the binding strip 20.
[0079] Preferably, the first concealed seam 213 is located on the first sub-folded edge 2031, so that the first part 21 can be fixed to the garment piece 10, and the distance from the first concealed seam 213 to the first side edge 211 is consistent with the seam width. This ensures that after the first part 21 wraps around the first side edge 211 of the garment piece 10, the edge of the first part 21 away from the first side edge 211 is fixed to the garment piece 10, effectively preventing the edge of the binding from curling up or folding over, thereby improving the binding quality of the garment 100.
[0080] Optionally, along the length of the first raw edge 11, the first distance t1 is greater than or equal to the distance from the first endpoint a to the first fold line 201. This facilitates the positioning of the binding strip 20, allowing the first part 21 to be partially fixed relative to the garment piece 10, while also allowing the portion of the first part 21 not sewn by the first hidden thread 213 to be movable, enabling further folding or turning of the binding strip 20 so that the first part 21 and the second part 22 of the binding strip 20 can respectively bind the first raw edge 11 and the second raw edge 12. Furthermore, it improves the integrity of the first hidden thread 213, preventing the thread from loosening due to cutting during subsequent sewing steps, thereby improving structural stability and reducing thread waste.
[0081] Preferably, along the length direction of the first rough edge 11, the first distance t1 is equal to the distance from the first endpoint a to the first fold line 201. At this time, the first dark line 213 intersects with the first marking line 206 at the first endpoint a, thereby ensuring the integrity of the first dark line 213 while maximizing the length of the first dark line 213, so that the fixation of the first part 21 to the garment piece 10 is more reliable.
[0082] S5. Fold the binding strip 20 to align the third side edge 221 with the second rough edge 12, and align the first fold line 201 with the first rough edge 11 (see [link]). Figure 8 ).
[0083] In this way, the binding strip 20 is a whole, with its first side 211 and third side 221 corresponding to the first rough edge 11 and the second rough edge 12 respectively, which is beneficial for the first part 21 and the second part 22 of the binding strip 20 to bind the first rough edge 11 and the second rough edge 12 respectively.
[0084] Understandably, at this time, the first part 21 and the second part 22 have overlapping portions, so that the first endpoint a corresponds to the third endpoint c, the second endpoint b corresponds to the fourth endpoint d, and the first marking line 206 corresponds to the second marking line 207.
[0085] Optionally, considering that the length direction of the first part 21 is parallel to the length direction of the first raw edge 11, and the length direction of the second part 22 is parallel to the length direction of the second raw edge 12, the length of the first part 21 is greater than or equal to the length of the first raw edge 11, and the length of the second part 22 is greater than the length of the second raw edge 12, so that the binding strip 20 can completely wrap the first raw edge 11 and the second raw edge 12 along the length direction of the first raw edge 11 or the second raw edge 12, thereby enabling the binding strip 20 to completely wrap the edge of the garment piece 10 and improve the quality of the binding of the garment 100.
[0086] S6. Along the length of the second raw edge 12, the second part 22 is sewn to the garment piece 10 to form a second hidden line 223, and the second hidden line 223 has a second distance t2 from the first raw edge 11.
[0087] By setting the second concealed thread 223, the binding strip 20 can be sewn and fixed to the garment piece 10, which is beneficial for the folding and positioning of the binding strip 20 in subsequent sewing steps, making the shape of the binding strip 20 neater and improving the quality of the binding of the garment 100. At the same time, considering that the garment piece 10 will be cut in the subsequent sewing steps, by limiting the second distance t2, the second concealed thread 223 can be prevented from being cut, thus avoiding the loosening of the sewing thread, improving structural stability, and reducing sewing thread waste.
[0088] Optionally, the second concealed line 223 is located between the second sub-fold 2032 and the first side edge 211, thereby securing the second part 22 to the garment piece 10 without affecting the folding of the binding strip 20.
[0089] Preferably, the second concealed seam 223 is located on the second sub-fold 2032, so that the second part 22 can be fixed to the garment piece 10, and the distance from the second concealed seam 223 to the third side 221 is consistent with the seam width. After the second part 22 wraps around the third side 221 of the garment piece 10, the edge of the second part 22 away from the third side 221 is fixed to the garment piece 10, so as to effectively prevent the edge of the binding from curling up or folding, thereby improving the binding quality of the garment 100.
[0090] Optionally, considering that the third endpoint c corresponds to the first endpoint a at this time, along the length direction of the second raw edge 12, the area from the third endpoint c of the second part 22 to the first fold line 201 partially overlaps with the first part 21. Based on this, along the length direction of the second raw edge 12, the second distance t2 is greater than or equal to the distance from the third endpoint c to the first fold line 201. This facilitates the positioning of the binding strip 20, allowing the second part 22 to be partially fixed relative to the garment piece 10, and also allows the portion of the second part 22 that is not sewn by the second hidden thread 223 to be movable, so as to fold or flip the binding strip 20, so that the first part 21 and the second part 22 of the binding strip 20 can respectively bind the first raw edge 11 and the second raw edge 12. In addition, it can also improve the integrity of the second hidden thread 223, avoid the situation where the thread is loosened due to the second hidden thread 223 being cut in subsequent sewing steps, thereby improving structural stability and reducing thread waste.
[0091] Preferably, along the length direction of the second rough edge 12, the second distance t2 is equal to the distance from the third endpoint c to the first fold line 201. At this time, the second dark line 223 intersects with the second marking line 207 at the third endpoint c, thereby maximizing the length of the second dark line 223 while ensuring its integrity, so as to make the fixation of the second part 22 to the garment piece 10 more reliable.
[0092] It is important to note that the first distance t1 and the second distance t2 can be equal or unequal. When the first distance t1 and the second distance t2 are unequal, the distance from the third endpoint c to the first fold line 201 along the length of the second raw edge 12 is less than or equal to the smaller of the two distances. For example, when the first distance t1 is less than the second distance t2, the distance from the third endpoint c to the first fold line 201 along the length of the second raw edge 12 is less than or equal to the first distance t1; when the first distance t1 is greater than the second distance t2, the distance from the third endpoint c to the first fold line 201 along the length of the second raw edge 12 is less than or equal to the second distance t2. This ensures the integrity of the first hidden thread 213 and the second hidden thread 223, preventing them from being cut in subsequent sewing steps and improving structural stability.
[0093] S7. Sew the first part 21 and the second part 22 together along the direction from the first fold line 201 to the fourth side 222 to form a first seam 23, the first seam 23 passing through the first intersection point p.
[0094] S8. Sew the first part 21 and the second part 22 together along the direction from the first fold line 201 to the third side 221 to form a second seam 24. The second seam 24 passes through the first intersection point p, and the first seam 23 and the second seam 24 are symmetrical with respect to the second sub-fold line 2022.
[0095] S9. Cut the binding strip 20 along the length of the first seam 23, while retaining the first seam 23 (see [link]). Figure 9 ).
[0096] S10. Cut the binding strip 20 and garment piece 10 along the length of the second seam 24, while retaining the second seam 24.
[0097] In this way, by setting the first seam 23 and the second seam 24, the cutting of the binding strip 20 and the garment piece 10 can be guided, and the first part 21 and the second part 22 can be sewn and fixed to improve the structural reliability of the binding strip 20.
[0098] Furthermore, by cutting the binding strip 20 and the garment piece 10, the fabric stacking at the corner O of the finished garment 100 can be reduced, thereby reducing the thickness of the edge of the garment 100 after binding (i.e., the sum of the thicknesses of the binding strip 20 and the garment piece 10). At the same time, the first seam 23 and the second seam 24 are retained to maintain the constraint of the first seam 23 and the second seam 24 on the binding strip 20 after cutting, thereby improving the structural reliability of the binding strip 20. This avoids the situation where the first part 21 and the second part 22 become extremely small due to the removal of the first seam 23 and the second seam 24 when cutting the binding strip 20, which could lead to the first part 21 and the second part 22 being torn during the folding process. Moreover, since the corner O of the garment piece 10 is removed when cutting, the constraint of the first seam 23 and the second seam 24 makes it easier for the binding strip 20 to be folded to form a new corner O in subsequent sewing steps, making the binding of the garment 100 neater and more beautiful.
[0099] Optionally, the first seam 23 is located between the second sub-fold line 2022 and the third fold 205, which facilitates the folding of the first part 21 along the first sub-fold 2031 and the folding of the second side 212 along the first rough edge 11, so as to avoid problems such as restricted folding of the binding strip 20 due to the restriction of the sewing thread, uneven binding, and the inability of the edge of the binding strip 20 to be wrapped inside.
[0100] Optionally, the second seam 24 is located between the second sub-fold line 2022 and the second sub-fold 2032, which facilitates the corner folding of the binding strip 20 so that the binding strip 20 can restore the shape of the garment piece 10 at the corner O, making the binding strip 20 neat and beautiful at the corresponding corner O, thereby improving the quality of the garment 100.
[0101] In some embodiments, as described above, in order to facilitate positioning during the sewing process, a first marking line 206 and a second marking line 207 are drawn. Based on this, the first sewing thread 23 can sew the first part 21 and the second part 22 along the first marking line 206 from the first intersection point p to the second endpoint b, and the second sewing thread 24 can sew the first part 21 and the second part 22 along the second marking line 207 from the first intersection point p to the third endpoint c, so that the positioning of the first sewing thread 23 and the second sewing thread 24 is more accurate. The first sewing thread 23 and the second sewing thread 24 respectively form a first included angle α with the second sub-fold line 2022.
[0102] Optionally, the first included angle α and the angle θ between the corner O of the garment piece 10 (i.e. the included angle between the first raw edge 11 and the second raw edge 12) satisfy the relationship: α=θ / 2.
[0103] This facilitates the folding and cornering of the binding strip 20, and helps the binding strip 20 restore the shape of the corner O of the garment piece 10 after folding, so that the appearance of the garment 100 is consistent with the shape of the garment piece 10, thereby improving the finished quality and aesthetics of the garment 100.
[0104] Optionally, as described above, the first marking line 206, the second marking line 207, the second side 212, and the fourth side 222 enclose a triangular first marking area 20a, and the first marking line 206, the second marking line 207, the first side 211, and the third side 221 enclose a triangular second marking area 20b. After folding, the first part 21 and the second part 22 overlap to form a three-layer structure. Based on this, the first seam 23 runs along the boundary of the first marking area 20a. The line (i.e., the line segment from the first intersection point p to the second endpoint b and the line segment from the first intersection point p to the fourth endpoint d) extends, and the second seam 24 extends along the boundary line of the second marking area 20b (i.e., the line segment from the first intersection point p to the third endpoint c and the line segment from the first intersection point p to the first endpoint a) to divide the first marking area 20a, the second marking area 20b, and the other areas of the binding strip 20, which are folded into a double-layer structure. After sewing, the first seam 23 and the second seam 24 are movable relative to the first sub-fold 2031.
[0105] Optionally, the specific area to be cut in step S9 is the first marked area 20a folded into a double-layer structure, thereby reducing the fabric stacking at the corner O and avoiding excessive local thickness of the finished garment 100.
[0106] Optionally, the specific area to be cut in step S10 is the second marking area 20b of the binding strip 20 folded into a double-layer structure and the part of the garment piece 10 corresponding to the second marking area 20b (including the corner O), thereby reducing the fabric stacking at the corner O and avoiding excessive local thickness of the finished garment 100.
[0107] In some embodiments, the cutting positions in steps S9 and S10 have a third distance from the first seam 23 and the second seam 24. The third distance is 0.2cm-0.3cm, for example, it can be 0.22cm, 0.25cm or 0.28cm, etc. This allows excess fabric to be cut off while retaining the first seam 23 and the second seam 24, thereby improving the structural reliability of the binding strip 20 and preventing the first part 21 and the second part 22 from being torn during folding in subsequent sewing steps. At the same time, based on the constraint of the first seam 23 and the second seam 24, it is beneficial for the binding strip 20 to be folded in subsequent sewing steps to form a new corner O, making the binding of the garment 100 neater and more beautiful.
[0108] It is understandable that steps S7 and S8 are not sequential; that is, in the actual sewing process, the first seam 23 can be formed first, or the second seam 24 can be formed first. Similarly, steps S9 and S10 are not sequential; that is, in the actual sewing process, the first marking area 20a of the binding strip 20 can be cut first, or the second marking area 20b of the binding strip 20 can be cut first. However, it is necessary to ensure that step S9 is performed after step S7 and step S10 is performed after step S8. This ensures that the first seam 23 and the second seam 24 can serve as markers during cutting, thus guiding the direction and position of the cutting.
[0109] S11. Fold the binding strip 20 to wrap the first part 21 around the first rough edge 11 and the second part 22 around the second rough edge 12.
[0110] This allows the binding strip 20 to wrap around the first raw edge 11 and the second raw edge 12 at the corner O of the garment piece 10, which helps to protect the first raw edge 11 and the second raw edge 12, prevents the edge yarn of the garment piece 10 from becoming loose, and improves the quality of the garment 100.
[0111] Please combine Figure 10 and Figure 11 , Figure 10 This is a schematic diagram of the front of garment 100 (i.e., the side of garment 100 furthest from the human body). Figure 11 This is a schematic diagram of the back of garment 100 (i.e., the side of garment 100 facing the human body). In this case, the first raw edge 11 and the second raw edge 12 are respectively wrapped by the first part 21 and the second part 22 to effectively protect the first raw edge 11 and the second raw edge 12 and extend the service life of the garment piece 10. Meanwhile, according to... Figure 11 It can be seen that the second side 212 of the first part 21 and the fourth side 222 of the second part 22 are exposed on the back of the garment 100.
[0112] Optionally, as mentioned above, the portion of garment piece 10 corresponding to the second marking area 20b has been cut off, and the corner O of garment piece 10 has also been removed. Based on this, for ease of understanding and reading, the intersection of the extension line of the first rough edge 11 and the extension line of the second rough edge 12 is defined as the second intersection point q, that is, the second intersection point q is located at the corner O position of garment piece 10 before cutting.
[0113] Please combine Figure 12 Specifically, step S11 above includes the following steps:
[0114] S11a. Fold the second part 22 along the second dark line 223 so that the second sub-fold line 2022 corresponds to the third side 221.
[0115] S11b Fold the first part 21 along the first dark line 213 so that the first sub-fold line 2021 corresponds to the first side 211 and the first intersection point p corresponds to the second intersection point q.
[0116] S11c, Fold the first part 21 along the first raw edge 11 toward the garment piece 10, and fold the second part 22 along the second raw edge 12 toward the garment piece 10, so that the first part 21 wraps the first raw edge 11 and the second part 22 wraps the second raw edge 12.
[0117] In this way, the binding strip 20 can simultaneously wrap the first raw edge 11 and the second raw edge 12. At the same time, the first fold line 201 corresponds to the first side 211 and the first raw edge 11, the second fold line 202 corresponds to the third side 221 and the second raw edge 12, and the first intersection point p corresponds to the second intersection point q, so that the first intersection point p forms a new corner O. Under the premise of cutting off the fabric at the corner O of the garment piece 10, the shape and angle of the garment piece 10 at the corner O are restored, so that the appearance of the garment 100 is consistent with the shape of the garment piece 10 before cutting. This ensures the finished quality of the garment 100 and reduces the thickness at the corner O of the garment 100.
[0118] S12. Fold the first part 21 toward the garment piece 10 to the second side 212, which corresponds to the first sub-fold line 2021. Fold the second part 22 toward the garment piece 10 to the fourth side 222, which corresponds to the second sub-fold line 2022.
[0119] Please see Figure 13 At this time, the second side 212 and the fourth side 222 are wrapped inside the binding strip 20 to effectively avoid the problem of loose edge yarn of the binding strip 20, improve the quality of the garment 100 and extend the service life of the garment 100.
[0120] S13. Sew the first part 21 to the garment piece 10 along the length of the first raw edge 11 to form a first visible seam 25, and sew the second part 22 to the garment piece 10 along the length of the second raw edge 12 to form a second visible seam 26 (see also...). Figure 14 ).
[0121] The first part 21 and the second part 22 are sewn and fixed to the garment piece 10 by the first visible thread 25 and the second visible thread 26 respectively, so as to complete the edge binding treatment of the garment piece 10. At the same time, the only sewing lines on the surface of the edge binding of the garment 100 are the first visible thread 25 and the second visible thread 26. The first visible thread 25 and the second visible thread 26 are formed in one sewing, so as to make the sewing lines on the surface of the garment 100 neat and beautiful, improve the consistency of the edge binding width, and thus improve the finished quality of the garment 100.
[0122] Optionally, the distance between the first sub-fold line 2021 and the first visible line 25 is 0.1cm-0.9cm, for example, 0.2cm, 0.3cm or 0.5cm, and the distance between the second sub-fold line 2022 and the second visible line 26 is 0.1cm-0.9cm, for example, 0.2cm, 0.3cm or 0.5cm.
[0123] This avoids the situation where the first visible thread 25, the second visible thread 26 overlap with the first concealed thread 213, and the second concealed thread 223, causing the seams to pile up and become locally hardened, thus improving the quality of the finished garment 100.
[0124] Secondly, the present invention provides a garment 100, which is obtained by the garment sewing method described in the first aspect. Specifically, the garment 100 includes a garment piece 10 and a binding strip 20. During the sewing process of the garment 100, the first marking area, the second marking area, and the corner position of the garment piece 10 are cut on the binding strip 20, while retaining the first seam 23 and the second seam 24, to reduce fabric stacking at the corners and avoid excessive local thickness of the finished garment 100. Finally, the binding strip 20 is folded over to wrap the first raw edge 11 and the second raw edge 12, and the first topstitch 25 and the second topstitch 26 are sewn on the surface of the binding strip 20 to sew the binding strip 20 to the garment piece 10. At this time, the only sewing lines on the surface of the binding of the garment 100 are the first topstitch 25 and the second topstitch 26. The first topstitch 25 and the second topstitch 26 are formed in one sewing, which makes the sewing lines on the surface of the garment 100 neat and beautiful, and improves the consistency of the binding width.
[0125] It is understandable that, since the garment is obtained using the garment sewing method described in the first aspect above, the garment has the beneficial effects of the garment sewing method described in the first aspect above, which will not be elaborated here.
