AI Technical Summary
Traditional pattern-making methods struggle to systematically and data-drivenly address the matching issues between the shoulder line and armhole in straight drop-shoulder sleeves. This results in skewed shoulder lines, armholes pressing against the arm, uneven connections between the sleeve and the garment body, and improper control of pattern ease, all of which affect the fit and aesthetics of the garment.
By scientifically determining the spatial relationship between the front and back shoulder drop points, accurately designing the armhole depth and width, and combining the sleeve cap shape, a straight-line drop shoulder sleeve pattern making process is adopted, including drawing the arm lift measurement, armhole opening depth position, and armhole curve, to ensure that the sleeve piece sits smoothly at the three-dimensional turning point of the human shoulder and arm, eliminating underarm wrinkles and sleeve cap emptiness, and achieving quantitative control of ease.
It achieves precise matching of shoulders and sleeves, preventing skewing and arm binding, eliminating wrinkles and looseness at the sleeve joint, ensuring a smooth and wrinkle-free finish after sewing, maintaining a relaxed drop-shoulder feel and avoiding excessive looseness, thus improving the fit and aesthetics of the garment.

Abstract
Description
Technical Field
[0001] This invention belongs to the field of clothing design technology, and specifically relates to a method for making straight-line drop-shoulder sleeve patterns, clothing patterns, and clothing. Background Technology
[0002] In the field of garment pattern making, the pattern making of straight-line dropped shoulders is a crucial step. Pattern makers need to accurately draw the paper pattern of straight-line dropped shoulders based on human body measurements and design style, using methods such as flat pattern making or three-dimensional cutting. This includes determining the position and angle of the shoulder line, the arc shape of the armhole, and the connection method between the sleeve and the garment body, to ensure the fit, comfort, and aesthetics of the garment. The core problem with traditional pattern making methods for this style is that it is difficult to systematically and data-drivenly solve the chain matching problems caused by structural changes, resulting in unstable garment effects. It relies heavily on the pattern maker's personal experience, which is specifically reflected in the following three aspects:
[0003] 1) Shoulder line and armhole matching: The "straight loose feeling" of the balanced dropped shoulder is not well matched with the armhole, resulting in a crooked shoulder line and the armhole being stuck to the arm.
[0004] 2) Connection between sleeve and body: Straight sleeves are prone to "empty sleeve caps" or "puffing fabric under the armpits", and wrinkles are likely to appear after sewing;
[0005] 3) Control of pattern ease: Excessive ease makes the garment look sloppy and affects movement.
[0006] Therefore, how to balance the straight, relaxed feel of the dropped shoulder with the fit of the armhole, avoid the shoulder line being crooked and the armhole being stuck to the arm, and ensure that the seam is flat and wrinkle-free after sewing, while retaining the casual feel of the dropped shoulder and avoiding excessive looseness, is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0007] In view of this, the purpose of the present invention is to provide a straight drop shoulder sleeve pattern making process that can balance the straight and relaxed feel of the drop shoulder with the fit of the armhole, avoid shoulder line skewing and armhole pinching, and ensure that the sewing is flat and wrinkle-free after sewing, while retaining the casual feel of the drop shoulder and avoiding excessive looseness.

[0017] S600: Determine the front and back chest circumferences: Move the second preset distance horizontally outward from the back armhole opening depth point T to obtain the second back chest position point;
[0018] The second anterior chest position is obtained by moving horizontally outward a third preset distance from the front armhole opening depth point U;

[0020] a) Draw the back armhole arc CV: passing through the back shoulder drop point C, the second back chest point and the back armhole opening depth point T, and control the arc to pass through the midpoint of the back armhole depth vertical line and shift downward by a fourth preset distance.
[0021] b) Draw the front armhole arc HW: passing through the front shoulder drop point H, the second front chest point and the front armhole opening depth point U, and control the arc to pass through the midpoint of the front armhole depth vertical line and shift downward by a fifth preset distance.
[0022] S800: Draw the side seam line smoothly: At the upper part of the side seam line of the front and back bodice, near the bottom of the armhole, indent the side seam line inward by the sixth preset distance and draw the side seam line smoothly.
[0023] S900: Determination of front and rear shoulder seam extension lines: Extend the front shoulder seam and the rear shoulder seam in the forward and backward directions respectively to form the front shoulder seam extension line HO and the rear shoulder seam extension line CN;

[0025] S1100: Sleeve Alignment: Align the center line of the front sleeve piece with the extension line HO of the front shoulder seam, and align the center line of the back sleeve piece with the extension line CN of the back shoulder seam to complete the pattern assembly of the straight drop shoulder sleeve.

[0036] As can be seen from the above technical solutions, compared with the prior art, the straight-line drop-shoulder sleeve pattern making process disclosed in the embodiments of the present invention has the following technical advantages:
[0037] 1) It can accurately solve the problem of shoulder and sleeve matching and prevent misalignment and arm compression: Through steps S100-S200, the spatial position relationship of the front and rear shoulder drop points C and H is scientifically determined, so that the sleeve can sit stably at the three-dimensional turning point of the human shoulder and arm. It not only retains the straight and relaxed outline of the shoulder line, but also provides the necessary ease of movement under the armpit by raising the arm. This effectively avoids the misalignment caused by uneven force on the shoulder line and the arm compression caused by insufficient armhole depth.
[0038] 2) Systematically eliminate wrinkles and gaps at the sleeve seam: Through steps S500, S600, and S1000, the depth, width, and sleeve cap shape of the armhole are designed and precisely matched in a coordinated manner, allowing the flat sleeve piece to fit into the three-dimensional armhole space. This effectively solves the common technical problems of armpit wrinkles and gaps at the top of the sleeve cap in straight sleeves, thus ensuring a smooth armpit area and a full sleeve cap after sewing.
[0039] 3) Intelligent control enables quantitative control of pattern looseness, avoiding excessive looseness that could affect personnel activities. Attached Figure Description

[0059] The pattern-making process for straight drop-shoulder sleeves disclosed in this invention includes the following steps:
[0060] S100: On the straight body prototype that has been balanced front and back, draw a horizontal line AB with the back shoulder point A as the reference, and determine the back shoulder point C on the extension line of the horizontal line AB according to the target shoulder drop amount.
[0061] S200: Obtain sleeve arm raise amount: Align the top point of the sleeve cap of the back sleeve prototype with the back shoulder point A, rotate the back sleeve prototype with the back shoulder point A as the center, so that the back sleeve center line intersects with the back shoulder drop point C, and obtain the back sleeve arm raise amount DE generated on the back sleeve cap; and determine the front sleeve arm raise amount FG associated with the back sleeve arm raise amount DE.
[0062] S300: Determine the front bodice shoulder point: Based on the distance AC from the top of the sleeve to the back shoulder drop point C on the back sleeve prototype, determine the corresponding equidistant points H and K on the front sleeve prototype, where HK=AC;
[0063] S400: Connect the front and back shoulder seams: Connect the back neck side point L and the back shoulder drop point C to form the back shoulder seam, and connect the front neck side point M and the front shoulder drop point H to form the front shoulder seam; S500: Determine the armhole opening depth position: Draw the first vertical line from the back shoulder drop point C, intersecting the horizontal line drawn from the first back chest point P to obtain the back intersection point R. Open the armhole depth downward from the back intersection point R along the first vertical line by a first set amount RT to obtain the back armhole opening depth point T.
[0064] Draw a perpendicular line at a first preset distance within the horizontal range of the front shoulder drop point H, intersecting the horizontal line drawn at the first front chest point Q, to obtain the front intersection point S. Then, along the first perpendicular line, open the armhole depth by a second preset amount SU downward from the front intersection point S to obtain the front armhole opening depth point U.
[0065] S600: Determine the front and back chest circumferences: Move the second preset distance horizontally outward from the back armhole depth point T to obtain the second back chest position point;
[0066] Move the front armhole opening point U horizontally outward by a third preset distance to obtain the second anterior chest position;
[0067] S700: Draw the armhole curve:
[0068] a) Draw the back armhole curve CV: passing through the back shoulder drop point C, the second back chest point and the back armhole opening depth point T, and control the curve to be offset downward by the fourth preset distance through the midpoint of the back armhole depth vertical line.
[0069] b) Draw the front armhole arc HW: passing through the front shoulder drop point H, the second front chest point and the front armhole opening depth point U, and control the arc to pass through the midpoint of the front armhole depth vertical line and shift downwards by the fifth preset distance.
[0070] S800: Draw the side seam line smoothly: At the upper part of the side seam line of the front and back bodice, near the bottom of the armhole, indent the side seam line inward by the sixth preset distance and draw the side seam line smoothly.
[0071] S900: Determination of front and back shoulder seam extension lines: Extend the front shoulder seam and back shoulder seam in the forward and backward directions respectively to form the front shoulder seam extension line HO and the back shoulder seam extension line CN;
[0072] S1000: Generate independent sleeve piece: Calculate the sleeve width size according to the formula 1 / 2 sleeve width = chest circumference / 5 - 3cm; draw the front sleeve cap by subtracting the seventh preset distance from the front armhole length; draw the back sleeve cap by subtracting the eighth preset distance from the back armhole length.
[0073] S1100: Matching the sleeve body: Align the center line of the front sleeve of the front sleeve piece 200 with the extension line of the front shoulder seam HO, and align the center line of the back sleeve of the back sleeve piece 100 with the extension line of the back shoulder seam CN to complete the paper pattern assembly of the straight drop shoulder sleeve.
[0074] Compared with the prior art, the straight drop shoulder sleeve pattern making process disclosed in the embodiments of the present invention has the following technical advantages:
[0075] 1) It can accurately solve the problem of shoulder and sleeve matching and prevent misalignment and arm compression: Through steps S100-S200, the spatial position relationship of the front and rear shoulder drop points C and H is scientifically determined, so that the sleeve can sit stably at the three-dimensional turning point of the human shoulder and arm. It not only retains the straight and relaxed outline of the shoulder line, but also provides the necessary ease of movement under the armpit by raising the arm. This effectively avoids the misalignment caused by uneven force on the shoulder line and the arm compression caused by insufficient armhole depth.
[0076] 2) Systematically eliminate wrinkles and gaps at the sleeve seam: Through steps S500, S600, and S1000, the depth, width, and sleeve cap shape of the armhole are designed and precisely matched in a coordinated manner, allowing the flat sleeve piece to fit into the three-dimensional armhole space. This effectively solves the common technical problems of armpit wrinkles and gaps at the top of the sleeve cap in straight sleeves, thus ensuring a smooth armpit area and a full sleeve cap after sewing.
[0077] 3) Intelligent control enables quantitative control of pattern looseness, avoiding excessive looseness that could affect personnel activities.
[0078] As a further embodiment, in the straight-line drop-shoulder sleeve pattern making process disclosed in this embodiment of the invention, in step S200: FG≤DE. Specifically, by ensuring that the ease amount of the front sleeve cap curve (corresponding to the arm raise amount FG) is not greater than or even slightly less than the back sleeve cap curve (corresponding to the arm raise amount DE), it is possible to ensure that the fabric in the front sleeve area (especially under the armpit) is flatter and neater when static, avoiding underarm piling due to excessive ease. Simultaneously, it ensures that when the arm performs regular forward and inward movements during movement, the ease amount provided by the back sleeve piece 100 just meets the activity requirements, while the larger ease amount DE provided by the back sleeve piece 100 provides sufficient allowance for scapular retraction and large-scale arm swing.
[0079] As a further embodiment, in the straight-line drop-shoulder sleeve pattern-making process disclosed in this invention, the values of the first setting amount RT and the second setting amount SU are equal, and both are half of the target drop-shoulder amount. This setting can increase the vertical relaxation while compensating for the underarm movement space, thereby achieving a balance between movement and stillness.
[0080] It should be noted that in step S500, the first preset distance is 1.5cm-2.5cm. Specifically, the first preset distance can be 1.5cm, 1.6cm, 1.8cm, 2.0cm, 2.3cm, or 2.5cm. This setting can scientifically construct a three-dimensional containment space for the front armhole and accurately resolve the interference between the chest and the armpit.
[0081] As a further embodiment, in step S600 disclosed in this embodiment of the invention, both the second preset distance and the third preset distance are 1.5cm-2.5cm. Specifically, the second preset distance can be 1.5cm, 1.8cm, 2.0cm, 2.1cm, 2.3cm, or 2.5cm, and the third preset distance can be 1.5cm, 1.8cm, 2.0cm, 2.1cm, 2.3cm, or 2.5cm.
[0082] This design creates a loose, triangular area between the armhole and the body when the arm is hanging down. When the arm is raised, this triangular area can expand smoothly, thus greatly eliminating the feeling of pressure and restraint under the armpit.
[0083] As a further embodiment, in step S700 disclosed in this embodiment of the invention, both the fourth preset distance and the fifth preset distance are 0.3cm-0.8cm. The fourth preset distance and the fifth preset distance can both be 0.3cm, 0.4cm, 0.5cm, 0.6cm, 0.7cm, or 0.8cm. This setting can significantly increase the curvature of the arc in the middle section region, thereby ensuring that the sleeve cap shape is full, the transition is smooth, and there are no sharp corners or twists after ironing.
[0084] As a further embodiment, in step S800 disclosed in this embodiment of the invention, the sixth preset distance is 1cm-2cm. Specifically, the sixth preset distance can be 1cm, 1.2cm, 1.5cm, 1.8cm, or 2cm. This setting, through optimization of the local shape, can make the side profile of the garment more fitted, cleverly balancing the boundaries between a loose and sloppy feel.
[0085] As a further embodiment, step S1000 disclosed in the embodiment of the present invention: the seventh preset distance is 0.8cm-1.2cm, wherein the seventh preset distance is specifically 0.8cm, 1.0cm or 1.2cm.
[0086] As a further embodiment, step S1000 disclosed in the present invention is: the eighth preset distance is 0.8cm-1.2cm, wherein the eighth preset distance may specifically be 0.8cm, 1.0cm or 1.2cm.
[0087] With this setting, the coordination of the seventh, eighth, and ninth preset distances ensures that the fabric at the sleeve joint is always in a pre-relaxed state, regardless of the arm's position.
[0088] To allow the sleeves to swing forward, the front sleeve cap height can be lowered by 0.5cm-1cm, and the back sleeve cap height can be raised by 0.5cm-1cm.
[0089] This invention also discloses a garment pattern, wherein the straight drop shoulder sleeve portion of the garment pattern is made using the straight drop shoulder sleeve pattern making process method disclosed in any of the above embodiments.
[0090] Since the garment pattern adopts the straight drop shoulder sleeve pattern making process disclosed in the embodiments of the present invention, the garment pattern also has the technical advantages of the straight drop shoulder sleeve pattern making process disclosed in the embodiments of the present invention, and the embodiments of the present invention will not elaborate on these advantages further.
