Description

Technical Field

[0001] This invention belongs to the field of clothing technology, and specifically relates to a three-dimensional three-piece sleeve and its pattern making method. Background Technology

[0002] In the structural design of down jackets, the sleeve design is a key element affecting the overall wearing experience and appearance, requiring a good balance between comfort, freedom of arm movement, and visual appeal. Currently, down jacket sleeve designs on the market are mainly divided into two basic types: one-piece sleeves and two-piece sleeves.

[0003] One-piece sleeve construction, consisting of a single sleeve piece, offers advantages such as simple manufacturing, convenient production, and low cost. However, due to its overall straight cylindrical shape, it is difficult to conform to the natural three-dimensional shape of the human arm when it is bent, especially in the elbow area where it can easily cause a feeling of ill-fittingness or restriction, affecting flexibility and comfort.

[0004] To address the shortcomings of one-piece sleeves in terms of fit, most down jackets now employ a two-piece sleeve structure. This structure divides the sleeve into a large sleeve piece and a small sleeve piece, which are sewn together to create a sleeve shape with a certain three-dimensional feel, improving the fit to the arm's curves to some extent. However, because the armpit and forearm areas have complex, multi-faceted curved surfaces, the cross-section of the traditional two-piece sleeve (S100) remains essentially elliptical (e.g., ...). Figure 2 As shown in the image, this leads to excess fabric piling up under the armpits when the arms are hanging naturally, creating noticeable wrinkles. This problem not only reduces the smoothness of the garment but also weakens the warmth retention efficiency of that area, causing heat loss.

[0005] In addition, because down jackets are filled with fluffy down material, their sleeves tend to expand visually in the radial direction, further aggravating the bulky feeling when worn, especially with obvious thickness accumulation on the sides of the sleeves, affecting the overall aesthetics and slimming effect.

[0006] Therefore, the existing sleeve structure of down jackets still suffers from problems such as insufficient conformity to the natural curve of the human arm, unavoidable underarm wrinkles, and a less than ideal slimming effect. There is an urgent need to optimize the structure based on the existing two-piece sleeve technology to better achieve a balance between comfort, freedom of movement, and visual appeal. Summary of the Invention

[0007] The purpose of this invention is to provide a three-dimensional three-piece sleeve and its pattern making method, which can achieve multiple effects such as visual slimming, comfortable movement and three-dimensional shape.

[0008] To solve the above-mentioned technical problems, the present invention provides a three-dimensional three-piece sleeve, comprising:

[0009] Step 1: Draw a basic one-piece sleeve pattern. Divide the one-piece sleeve into one large sleeve and two smaller sleeve pieces according to the proportions. Combine the two smaller sleeve pieces into one small sleeve to form two sleeves. There is no seam at the bottom of the armhole.

[0010] Step 2: Based on the two sleeve pieces, rotate and adjust the seam of the large sleeve and the small sleeve forward from the elbow to the cuff to form a forward-curving arc, and smooth the arc to fit the natural forward-leaning state of the arm.

[0011] Step 3: Divide the two sleeves again, dividing the large sleeve into a front sleeve and a back sleeve to form a three-piece sleeve. Sew the three-piece sleeve together to create a three-dimensional three-piece sleeve tube.

[0012] Optionally, in the above pattern-making method, in step one, a basic sleeve pattern is drawn based on the armhole arc length of the body and the sleeve width, sleeve cap height and cuff size of the design.

[0013] Optionally, in the above pattern-making method, in step one, the proportion of dividing a sleeve into a large sleeve and two smaller sleeve pieces is as follows: the armhole arc length and cuff length of the large sleeve are 1.8–2.2 times the armhole arc length and cuff length of the two smaller sleeve pieces.

[0014] Optionally, in the above plate-making method, in step two, the bending amount of the forward-bending arc is controlled within the range of 1.5cm-3.0cm.

[0015] Optionally, in the above pattern-making method, for the three-dimensional three-piece sleeve of lightweight thermal clothing, after sewing the three-piece sleeve, thermal insulation material is filled into the sleeve tube to form a three-dimensional three-piece sleeve tube.

[0016] Optionally, in the above-described pattern-making method, the insulating material is down jacket, sponge, or bubble wrap.

[0017] Optionally, in the above plate-making method, in steps one and three, the dividing line is a curve or a straight line arranged longitudinally.

[0018] Optionally, in the above pattern-making method, in step one, the large sleeve occupies 60%-70% of the width of the entire sleeve piece, and the two divided small sleeve pieces each occupy 15%-20%.

[0019] The present invention also provides a three-dimensional three-piece sleeve, which uses the pattern making method of the three-dimensional three-piece sleeve described above, wherein the cross-section of the sleeve tube of the three-dimensional three-piece sleeve is triangular.

[0020] Optionally, in the above-mentioned three-dimensional three-piece sleeve, the three-dimensional three-piece sleeve is used to manufacture down jackets, coats, or jackets.

[0021] This invention provides a pattern-making method for a three-dimensional three-piece sleeve, the advantages of which are:

[0022] Step 1: Prepare a basic sleeve pattern and make initial cuts; Step 2: Adjust the seam curves to fit the forward-leaning arm; Step 3: Cut again to form a three-piece sleeve and complete the production. Using these three steps, the resulting three-piece sleeve not only conforms to ergonomics but also achieves multiple effects such as a slimming effect, comfortable movement, and a three-dimensional shape.

[0023] The present invention also provides a three-dimensional three-piece sleeve. The pattern making method of the three-dimensional three-piece sleeve described above has the same beneficial effects, which will not be elaborated here. Attached Figure Description

[0040] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0041] The core of this invention is to provide a three-dimensional three-piece sleeve and its pattern making method, which achieves multiple effects such as visual slimming, comfortable movement and three-dimensional shape while ensuring the warmth function of down jacket.

[0042] To enable those skilled in the art to better understand the technical solutions provided by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] For details, please refer to Figures 3-7 The present invention provides a method for pattern making of a three-dimensional three-piece sleeve, comprising:

[0044] Step 1: Prepare a basic sleeve paper template and perform preliminary division:

[0045] like Figure 4 As shown, firstly, based on the garment design requirements and human arm dimensions, a paper pattern for a basic one-piece sleeve 110 is drawn (see a1). The basic one-piece sleeve 110 can be obtained using conventional garment pattern-making methods, such as designing based on parameters like sleeve length, sleeve width, sleeve cap height, and cuff width. The one-piece sleeve 110 is then divided into a large sleeve 120 and two smaller sleeve pieces 131 according to a predetermined ratio (see a2). The two smaller sleeve pieces 131 are then joined together to form a small sleeve 130, creating a two-piece sleeve with no seam at the armhole (see a3). The dividing line 200 can be designed as a straight line, curve, or diagonal line along the longitudinal direction to enhance the styling diversity.

[0046] It should be noted that the predetermined proportions can be determined according to the sleeve design requirements. For example, the large sleeve 120 may occupy 60%-70% of the total sleeve width, while the two smaller sleeve pieces 131 may each occupy 15%-20%, thus ensuring that the large sleeve 120 is the main sleeve piece and the smaller sleeve pieces 130 are auxiliary sleeve pieces. The dividing line 200 is set longitudinally along the sleeve piece, extending from near the top of the sleeve apex to the cuff, but the bottom of the armhole (i.e., the underarm area) remains seamless to avoid additional seams affecting comfort. After dividing, the two smaller sleeve pieces 131 are joined together along their edges to form a smaller sleeve 130, resulting in a two-piece sleeve structure consisting of the large sleeve 120 and the smaller sleeve 130. When joining, it is necessary to ensure that the seams of the smaller sleeve 130 are smooth and wrinkle-free.

[0047] Step 2: Adjust the seam curve to fit the forward-leaning arm:

[0048] like Figure 5 As shown, after obtaining the two sleeve pieces (including the large sleeve 120 and the small sleeve 130) (see b1, which is a3), the seam between the large sleeve 120 and the small sleeve 130 is rotated forward and adjusted from the elbow to the cuff (the elbow point is located approximately 5cm-10cm above the midpoint of the sleeve length, corresponding to the position of the elbow joint on the human body) (see b2), forming a forward-curving arc. The arc is then smoothed to conform to the natural forward-leaning posture of the arm (see b3). It should be noted that the offset amount can be determined according to the sleeve length and design requirements. For example, an offset of 1cm-3cm forward at the cuff ensures a smooth transition and avoids sharp angles. After adjustment, a curve ruler or computer-aided design software is used to smooth the arc, ensuring that the seam line between the large sleeve 120 and the small sleeve 130 presents a natural and smooth curve. This step allows the sleeve to better conform to the forward-leaning posture of the arm after sewing, improving freedom of movement and comfort.

[0049] Step 3: Divide the sleeve again to form three pieces and complete the production:

[0050] Based on the two sleeve pieces adjusted in step two (see c1, same as b3), the two sleeve pieces are further divided to enhance the three-dimensional effect. The large sleeve 120 is divided longitudinally into a front sleeve 140 and a back sleeve 150. The dividing line 200 can be set in the middle or slightly forward of the large sleeve 120. After division, a three-piece sleeve structure consisting of the front sleeve 140, the back sleeve 150, and the small sleeve 130 is obtained (see c2). Subsequently, the three-piece sleeve is sewn together, with the front sleeve 140, the back sleeve 150, and the small sleeve 130 joined along the seam line. When sewing, attention should be paid to the alignment of the curved lines to ensure that the overall sleeve tube is smooth. This forms a three-dimensional three-piece sleeve tube.

[0051] This invention provides a method for fabricating a three-dimensional three-piece sleeve, comprising: Step 1, preparing a basic one-piece sleeve pattern and performing preliminary division; Step 2, adjusting the seam curve to fit the forward-leaning arm; Step 3, dividing again to form the three-piece sleeve and completing the fabrication. Through the above steps, the resulting three-piece three-piece sleeve not only conforms to ergonomics but also achieves multiple effects such as visual slimming, comfortable movement, and a three-dimensional shape.

[0052] In a specific embodiment, in step one, a basic sleeve pattern is drawn based on the arc length of the armhole and the sleeve width, sleeve cap height and cuff size (28cm-40cm) of the design.

[0053] In step one, the sleeve is divided proportionally into a large sleeve 120 and two smaller sleeve pieces 131. The proportions are as follows: the armhole arc length and cuff length of the large sleeve 120 are 1.8–2.2 times that of the two smaller sleeve pieces 131. The division ratio can be adjusted according to the looseness of the sleeve. For loose sleeves, the proportion of the large sleeve 120 can be increased to over 70%. For fitted sleeves, the proportion of the smaller sleeve pieces 131 can be appropriately increased.

[0054] like Figure 1 As shown, when a person's arm hangs naturally, the midline of the wrist forms a natural angle of approximately 5°-10° with the vertical line of the arm. Therefore, the sleeve structure must conform to this physiological curvature and allow for adequate range of motion to ensure comfort.

[0055] Based on the above characteristics, in step two, the bending amount of the forward-bending arc is controlled within the range of 1.5cm-3.0cm. The arc adjustment can be optimized based on 3D human body scan data, and the offset can be accurate to the millimeter level.

[0056] The core technology of this invention lies in transforming the semi-elliptical cross-section of the traditional sleeve into a triangular cross-section through structural segmentation and bending treatment, combined with the proportional control (1.8–2.2 times relationship) of the large sleeve 120 and the segmented small sleeve pieces 131, and the forward bending design (1.5cm–3.0cm). Through multi-step segmentation and arc optimization, the problems of traditional sleeves being stiff and not fitting well are solved, significantly improving the functionality and aesthetics of the garment.

[0057] For lightweight, warm clothing with three-piece sleeves, in step three, after sewing the three-piece sleeve, insulating material is filled into the sleeve tube to form a three-piece sleeve tube. For example, in down jackets, down is filled into the sleeve tube; the amount of down filler can be adjusted according to warmth requirements to form a three-piece sleeve tube. The pattern-making method for down jackets is as follows... Figure 7 As shown.

[0058] The above pattern-making method is illustrated using the production of down jacket sleeves as an example, but the present invention is also applicable to other garments that require three-dimensional sleeves, such as coats and jackets.

[0059] Of course, insulation materials can also be made of materials such as sponge or bubble wrap, but down filling is preferred for lightweight thermal clothing.

[0060] It should be noted that because the large sleeve 120 is divided into a front sleeve 140 and a back sleeve 150, the newly added seam line can directionally constrain and guide the down filling, forcing the down to redistribute along the seam direction within the sleeve. This transforms the originally naturally expanded elliptical cross-section into a visually thinner and more stable triangular three-dimensional structure composed of sloping surfaces. While ensuring the warmth of the down jacket, it also achieves multiple effects such as a slimming effect, comfortable movement, and a three-dimensional shape.

[0061] In addition, the present invention also provides a three-dimensional three-piece sleeve, which uses the pattern-making method of the three-dimensional three-piece sleeve in the above specific embodiment. The sleeve tube of the three-dimensional three-piece sleeve made by the above pattern-making method has a triangular cross-section.

[0062] like Figure 3 As shown, the sleeve shape has changed from the traditional semi-ellipse to a triangle, and the armhole arc length and cuff length of the large sleeve 120 are 1.8-2.2 times that of the two divided small sleeve pieces 131, which are approximately equilateral triangles, forming a stable and visually slimmer three-dimensional silhouette.

[0063] Three-dimensional sleeves can be used to manufacture garments such as down jackets, coats, or jackets that require a three-dimensional sleeve design.

[0064] The beneficial effects of the technical solution provided by this invention include:

[0065] 1. Slimming visual effect: The three-piece proportion and seam layout guide the down to be evenly distributed in the sleeve and form a fulcrum, thereby transforming the semi-elliptical cross section of the traditional sleeve into a stable triangular cross section, breaking the bulky feeling of the down jacket sleeve and achieving a visually neat and slimming effect.

[0066] 2. Comfort of movement: Based on the natural forward curvature of the arm, a forward bend is precisely added from the elbow to the cuff, so that the sleeve shape is highly consistent with the dynamics of the human body. This not only solves the limitation of movement imposed by traditional sleeve types, but also avoids the accumulation of excess fabric under the armpits and elbows, significantly enhancing the smoothness, comfort and freedom of movement of the garment.
