Take the arc line of the first front armhole and make the first front armhole The arc point O intersects with point O', and a vertical extension line through point O' is made as the symmetry line. The first front armhole arc is symmetrical with the symmetry line to obtain the second front armhole arc. The midpoint M of the horizontal line L3 is taken, and the first tangent line of the second front armhole arc is made through point M. The tangent point is point M'. The intersection point of the first tangent line and the front sleeve cap oblique line is point M", and the arc A'M" is connected with point A' and point M", and the arc A'M" is tangent to the first tangent line and the horizontal line L3 respectively, so as to obtain the front sleeve cap arc A'M"M'O';
[0008] Take out the back sleeve piece, select any point B' on the back sleeve piece, draw a vertical line L4 from point B', and draw a point B" on the vertical line L4, so that the length of line segment B'B" is equal to the height h of the armhole. Draw a horizontal line L5 from point B", extend the horizontal line L5 to the right, draw a front sleeve cap oblique line through point B' and intersect the horizontal line L5 at point O", and draw a horizontal line L6 extending to the right with point B' as the endpoint.

[0009] The sleeve cap arc is obtained by connecting point A' of the front sleeve cap arc line A'M"M'O' with point B' of the rear sleeve cap arc line B'N"N'O"
[0010] Beneficial effects:
[0011] The design method of the sleeve cap curve of the form-fitting sleeve disclosed in the present application matches the sleeve cap curve with the armhole curve, and the front and rear sleeve cap curves and the front and rear armhole curves are completely matched at a certain length at the bottom of the armhole, so that the sleeves of the finished garment can be completely matched with the body of the garment at the bottom of the armhole, making it more beautiful and avoiding the problem of sleeve accumulation under the armpit.

[0018] Because a chord-arc difference will be generated when drawing an arc with a straight line as a reference, shortening the front sleeve cap slant line and the back sleeve cap slant line by 1-1.5cm can effectively reduce the error and avoid the situation where the front and back sleeve cap arcs and the front and back armhole arcs do not match each other.

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
[0036] Combine the following Figures 1 to 5 , describing an embodiment of the present invention.
[0037] According to an embodiment of the present invention, a method for designing a sleeve cap curve of a form-fitting sleeve is provided, comprising the following steps:
[0038] Step 1: Design the body structure above the waist, including the front and back pieces.
[0039] Step 2: Draw the first front armhole arc line OA, the first back armhole arc line OB and the three-dimensional armhole eye height h according to the body structure.
[0040] In this embodiment, if Figure 4 As shown, first determine the front shoulder endpoint A on the front piece and the back shoulder endpoint B on the back piece according to the body structure, and draw the first front armhole arc OA and the first back armhole arc OB according to the front shoulder endpoint A and the back shoulder endpoint B. Point O is the midpoint of the armhole width. Draw a horizontal line through point A and intersect the first back armhole arc OB at point D. Take the midpoint E of arc BD, and draw an extension line of the first front armhole arc OA through point A to point E'. The length of arc AE' is equal to the length of arc DE. Point E' and point E are on the same horizontal line. Figure 5 As shown, take the midpoint G of arc E'O, draw a vertical line through point G and intersect the bust line 5 at point F, extend line segment FG away from the bust line 5 to point F', make FG and GF' equal in length, and line segment FF' is the armhole height h.
[0041] Specifically, Figure 5 As shown, take the midpoint H of arc EO, draw a vertical line through point H and intersect the bust line 5 at point I, extend line segment IH to I' in the direction away from the bust line 5, make IH and HI' equal in length, connect points F' and I', connect points G and H, arc GO takes line segment GH as the symmetry line to obtain arc GC, arc HO takes line segment GH as the symmetry line to obtain arc HC, CGOH is the armhole, arc E'G and arc GO are equal in length, so arc E'G and arc GC are of equal length; arc EH and arc HO are of equal length, so arc EH and arc HC are of equal length, the length of line segment OC is the armhole height h, arc GC and arc HC are tangent to line segment F'I', and the tangent point is point C. It can be seen that point C, point F', and point I' are on the same horizontal line, and point O, point F, and point I are on the same horizontal line. Therefore, the length of line segment OC is the same as that of line segment FF' and line segment II'. Therefore, line segment FF' is the armhole height h.
[0042] In this embodiment, point E' is at the same height as point E, and point O is the midpoint of the armhole width, so arc E'O is equal to arc EO (error is negligible), and the midpoint G of arc E'O and the midpoint H of arc EO are at the same height.
[0043] It should be noted that there is a large error between the height of the plane armhole eyelet designed by the related technology and the height of the three-dimensional armhole eyelet. The three-dimensional armhole eyelet is the armhole eyelet formed after the front and back pieces are sewn into a finished garment. In the related technology, the armhole eyelet height is determined by taking 4 / 5 of the armhole height, and the armhole width is not considered. Regardless of the armhole width, the armhole eyelet height is the same, so the following situation may occur: when the armhole width becomes wider, the armhole arc will become longer, but the armhole height will not change. After the finished garment is made, the three-dimensional armhole eyelet after sewing will become shorter due to the longer armhole arc, resulting in a smaller height of the armhole eyelet, which causes the armhole eyelet height to be smaller according to the related technology. The high armhole eyelet obtained by the technology cannot match the three-dimensional armhole eyelet, and the sleeve cannot droop smoothly and naturally, resulting in the problem of uneven fabric accumulation at the armpit of the inner seam of the sleeve; when the armhole width becomes narrower, the armhole arc will become shorter, but the height of the armhole does not change. After the finished garment is made, the three-dimensional armhole eyelet after sewing will become higher due to the shorter armhole arc line, resulting in the height of the armhole eyelet becoming larger, causing the sleeve body produced according to the high armhole eyelet obtained by the relevant technology to not match the three-dimensional armhole eyelet, and the sleeve cannot droop smoothly and naturally, and the problem of uneven fabric accumulation will also appear at the shoulder end of the sleeve length line.
[0044] The method for designing the armhole eye height disclosed in the present embodiment is to determine the plane armhole eye and the plane armhole eye height according to the length of the armhole arc by making the front armhole arc and the back armhole arc equal in length, and to determine the plane armhole eye height after the garment pieces are made into finished garments, because the armhole eye height of the present embodiment is determined according to the length of the armhole arc, the plane armhole eye height and the three-dimensional armhole eye height are the same, and the sleeve body made according to the plane armhole eye height is also matched with the three-dimensional armhole eye, so as to ensure that the sleeve can droop smoothly and naturally.
[0045] Step 3: If Figure 2 As shown, take out the front sleeve piece, select any point A' on the front sleeve piece, and move from point A' to Figure 2 Draw a vertical line L1 on the "lower" side pointed by the middle arrow, and draw a point A" on the vertical line L1. Make the length of the line segment A'A" equal to the height h of the armhole. Figure 2 Draw a horizontal line L2 on the "left" side pointed by the middle arrow. Figure 2 Extend to the "left" direction indicated by the middle arrow, and make a front sleeve slope line 1 through point A', intersecting the horizontal line L2 at point O'. Figure 2 The horizontal line L3 extending to the "left" direction indicated by the middle arrow passes through the midpoint of L2 and points to Figure 2 The vertical extension line of the "upper" side pointed by the middle arrow intersects at the other end point of L3. The length of the horizontal line L3 is 1 / 2 of the line segment A"O'. Take the first front armhole arc line and make the first front armhole arc line point O intersect with point O', and pass through point O' to Figure 2The vertical extension line (not shown) of the "upper" side pointed by the middle arrow is the symmetry line, and the first front armhole arc line is symmetrically extended from the symmetry line to the Figure 2 The second front armhole arc 2 is obtained symmetrically on the "right" side pointed by the middle arrow, and the midpoint M of the horizontal line L3 is taken. The first tangent of the second front armhole arc 2 is made through point M, and the tangent point is point M'. The intersection of the first tangent and the front sleeve cap oblique line 1 is point M", and the arc A'M' is connected with point A' and point M". The arc A'M" is tangent to the first tangent and the horizontal line L3 respectively, and the front sleeve cap arc A'M"M'O' is obtained.
[0046] Specifically, the first front armhole arc OA is 1-1.5 cm longer than the front sleeve cap oblique line 1. Because a chord arc difference will be generated when drawing an arc with a straight line as a reference, shortening the front sleeve cap oblique line 1 by 1-1.5 cm can effectively reduce the error and avoid the situation where the front sleeve cap arc and the front armhole arc do not match. Preferably, in this embodiment, the first back armhole arc OA is 1.2 cm longer than the back sleeve cap oblique line 3.
[0047] Step 4: If Figure 3 As shown, take out the back sleeve piece, select any point B' on the back sleeve piece, and move from point B' to Figure 3 Draw a vertical line L4 on the "lower" side pointed by the middle arrow, and draw a point B" on the vertical line L4. Make the length of the line segment B'B" equal to the height h of the armhole. Figure 3 Draw a horizontal line L5 on the "right" side pointed by the middle arrow. Figure 3 Extend to the "right" direction indicated by the middle arrow, and make a front sleeve slope line 1 through point B', intersecting the horizontal line L5 at point O", with point B' as the endpoint. Figure 3 The horizontal line L6 extending to the "right" direction indicated by the middle arrow passes through the midpoint of L5 and points to Figure 3 The vertical extension line of the "upper" side pointed by the middle arrow intersects at the other end of L6. The length of the horizontal line L6 is 1 / 2 of the line segment B"O". Take the first back armhole arc line and make the first back armhole arc line point O intersect with point O", and pass through point O" to Figure 3 The vertical extension line (not shown) of the "upper" side indicated by the middle arrow is the symmetry line, and the first rear armhole arc line is symmetrically extended toward the Figure 3 The second rear armhole arc 4 is obtained symmetrically on the "left" side pointed by the middle arrow, the midpoint N of the horizontal line L6 is taken, and the second tangent of the second rear armhole arc 4 is made through point N, and the tangent point is point N', the intersection of the second tangent and the rear sleeve cap oblique line 3 is point N", connecting point B' and point N" to make arc B'N", arc B'N" is tangent to the second tangent and the horizontal line L6 respectively, to obtain the rear sleeve cap arc B'N"N'O".
[0048] Specifically, the first rear armhole arc line OB is 1-1.5 cm longer than the rear sleeve cap oblique line 3. Preferably, in the present embodiment, the first rear armhole arc line OB is 1.2 cm longer than the rear sleeve cap oblique line 3.
[0049] Step 5: If Figure 1 As shown, the sleeve cap arc is obtained by connecting point A' of the front sleeve cap arc A'M"M'O' and point B' of the rear sleeve cap arc B'N"N'O".
[0050] The design method of the sleeve cap curve of the form-fitting sleeve disclosed in this embodiment is that the sleeve cap curve matches the armhole curve, and the front and rear sleeve cap curves and the front and rear armhole curves completely match each other at a certain length at the bottom of the armhole, so that the sleeves of the finished garment can completely fit the body of the garment at the bottom of the armhole, ensuring that the sleeves can droop smoothly and naturally, making them more beautiful.
[0051] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
