The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] Example: See Figure 1 A qipao making process includes the following steps: S1. Take measurements and collect the wearer's net dimensions; S2. Design Finalization: Confirm the design elements, main fabric, lining, and accessories of the cheongsam with the wearer; S3. Determine the ease allowance based on the design and fabric of the cheongsam and the wearer's net measurements; S4. Pattern making and cutting: Pattern making: This includes the creation of basic paper patterns, collar processing, and marking of finishing processes; Cutting: This includes pre-shrinking, layout, pattern drawing, and cutting processing; S5.

Ironing and Quality Inspection: This includes using ironing tools for three-dimensional ironing and final quality inspection.

[0023] In step S1 above, the wearer's net measurements are collected, including neck circumference, chest circumference, waist circumference, abdominal circumference, hip circumference, garment length, shoulder width, chest height, chest distance, front waist length, back waist length, side slit height, arm circumference, sleeve length, collar height, front flatness, and back flatness. It is also important to record any special body shape characteristics, such as hunchback, upright posture, or sloping shoulders, so that targeted adjustments can be made during pattern making.

[0024] The side slit height is set at a position 15cm above the knee, perpendicular to the bust point, above the shoulder and neck. This is suitable for both long and short cheongsams.

[0025] In step S2 above, the design elements of the cheongsam include its silhouette, collar, sleeves, opening, buttons, and piping. The silhouette includes A-line, H-line, and X-line shapes; the collar includes Shanghai collar, ingot collar, and wave collar; the sleeves include sleeveless, raglan sleeves, wide-sleeved sleeves, and cap sleeves; the opening includes ruyi-shaped, slanted, double-round, and straight openings; the buttons include single-button, pipa-shaped, butterfly, and flower buttons; and the piping includes incense thread piping, wide piping, and inlaid piping, among other design elements.

[0026] In step S4 above: Basic pattern making: Based on the body measurement data in step S1 and the final design draft determined in step S2, use the principle of flat pattern making to draw 1:1 rough patterns of the front and back pieces, large sleeves, small sleeves, collar pieces, and front panels of the cheongsam. Collar treatment: The slope of the collar stand is designed to ensure that the collar fits the curve of the neck; Marking for shaping: Mark the parts that need to be shaped on the above-mentioned rough pattern paper in advance to prepare for subsequent three-dimensional shaping. Pre-shrinkage: The main fabric and lining are pre-shrinked to prevent deformation after the garment is made; Arrange the above-mentioned rough patterns on the fabric according to the grain direction, paying special attention to matching stripes, checks, and patterns, as well as the directional requirements of directional fabrics (such as printed and velvet fabrics). Drawing: Using chalk or a water-soluble pen, trace the outline of the above-mentioned rough pattern onto the fabric, and mark the darts and alignment points; Cutting process: Using a cutting device, cut along the outline formed by the above drawing. First cut the main fabric, and then cut the lining according to the main fabric.

[0027] In the cropping process: see [link] Figures 2 to 4 The cutting device includes a cutting base 1, a worktable 2, a cutting mechanism, and a flattening mechanism; wherein... Figure 2 The leveling mechanism is shown as a cross-sectional view of its internal structure.

[0028] Workbench 2 is located at the cutting base 1, and the cutting mechanism and flattening mechanism are located at workbench 2, with the flattening mechanism located on both sides of the cutting mechanism. The cutting mechanism includes a cutting support 3, a cutting drive device 4, a cutting blade body 5, a cutting plate body 6, and a cutting flattening assembly. The cutting support 3 is connected to the workbench 2. The cutting drive device 4 is located at the cutting support 3. The cutting plate body 6 is connected to the drive end of the cutting drive device 4. The cutting blade body 5 and the cutting flattening assembly are located on the cutting plate body 6. The cutting and flattening components are respectively located on both sides of the cutting blade body 5. The cutting and flattening components include a first flattening wheel body 7, a first rotating rod 8, a second rotating rod 9, a first spring member 10, and a first sleeve member 11. One end of the first rotating rod 8 is hinged to the cutting plate body 6, and the other end is rotatably engaged with the first flattening wheel body 7. One end of the first sleeve member 11 is hinged to the cutting plate body 6, and the other end is slidably engaged with one end of the second rotating rod 9. The other end of the second rotating rod 9 is hinged to the first rotating rod 8. The first spring member 10 is located inside the first sleeve member 11 and abuts against one end of the second rotating rod 9. The leveling mechanism includes a leveling bracket 12, a leveling plate 13, a second flattening wheel 14, and a second spring 15. The leveling bracket 12 is connected to the worktable 2, the leveling plate 13 is slidably engaged with the leveling bracket 12, the second spring 15 is located between the leveling bracket 12 and the leveling plate 13, and the second flattening wheel 14 is rotatably engaged with the leveling plate 13.

[0029] Furthermore, a groove is provided on the worktable corresponding to the position of the cutting scissors, which facilitates the cutting of fabric when the cutting scissors are engaged with the groove.

[0030] Specifically, the steps for cutting using a cutting device are as follows: Place the fabric on the workbench 2, slide and adjust the flattening plate 13 and the flattening bracket 12 to move the second flattening wheel 14 away from the workbench 2, place both ends of the fabric under the second flattening wheel 14, slide and adjust the flattening plate 13 and the flattening bracket 12 again to make the second flattening wheel 14 abut against the ends of the fabric, control the cutting drive device 4 to move the cutting plate 6 toward the fabric, and make the cutting blade 5 correspond to the position of the outline to complete the cutting.

[0031] In the structure of the above-mentioned cutting device, by activating the cutting drive device 4, specifically in this embodiment, the cutting drive device 4 can be an electric telescopic cylinder. Through its telescopic rod, the cutting plate 6 is moved, causing the first flattening wheel 7 of the cutting and flattening assembly to contact the fabric. The cutting plate 6 continues to descend, causing the first rotating rod 8 to drive the second rotating rod 9 to deflect. The second rotating rod 9 slides inside the first sleeve 11, causing the first spring 10 to compress and deform. This causes the second rotating rod 9 to apply force to the first rotating rod 8, so that the first flattening wheel 7 presses the fabric firmly, preventing the fabric from misaligning during the cutting process of the cutting blade 5, ensuring the accuracy of the cutting. At the same time, during the deflection process of the second rotating rod 9, the first flattening wheel 7 flattens the surface of the fabric, avoiding wrinkles in the fabric during cutting.

[0032] The flattening mechanism also includes a lifting plate 13, which raises the second pressing wheel 14 and compresses the second spring 15, causing it to deform and position the end of the fabric below the second pressing wheel 14. As the second spring 15 recovers, the flattening plate 13 moves down and recovers, allowing the second pressing wheel 14 to press and flatten the fabric, further eliminating wrinkles and preventing them from affecting the fabric cutting.

[0033] In step S5 above: Ironing and shaping: Using an iron, the side seams and waist area of ​​the front and back pieces of the cheongsam are shrunk and stretched. For example, the waist area is stretched to make it fit better; the curves of the hips are shrunk and gathered to make them rounder and fuller. This process gives the flat fabric a three-dimensional shape that conforms to the curves of the human body.

[0034] Pre-stitching and fitting: The garment pieces and darts are temporarily connected and combined to form a blank sample garment. The wearer tries on the blank sample garment and checks the overall balance, looseness, smoothness of the lines, and fit of each detail of the cheongsam based on the fitting. The parts that need to be modified are marked. This process may be repeated 1-2 times to ensure a perfect fit.

[0035] Suturing and Treatment: Sew the darts and side seams: According to the markings after the darts and fitting modifications, use a flat sewing machine to precisely sew each dart and side seam, and iron the seams separately to make the seams flat; Making the lining: Sew the lining fabric using the same method as the above-mentioned method for sewing darts and side seams, and leave a folded opening at the hem of the side seam; Applying a stripe: Apply a stripe with a straight grain to the neckline, shoulder line, and placket areas that are prone to deformation.

[0036] In step S5 above: Components to be made: Making the collar: Combine the collar outer layer, collar lining, and collar interlining into one piece, sew them together using the hook and press method, turn them inside out, iron them to shape them, and form a stand-up collar; Making the sleeve: Sew the sleeve outer fabric and sleeve lining together to form the sleeve body; Making Chinese knot buttons: After scraping the bias-thread fabric strips to form a button strip, coil it into a pattern, and sew on the button loops and button heads to form a Chinese knot button; Assembly components: Attaching the collar: Sew the collar to the neckline of the garment in alignment; Sleeve attachment: Sew the sleeves to the armhole of the garment and check the front and back positions and range of motion; Making the front opening: finishing the front opening area; Piping and Chinese knot buttons: Piping: Cut the fabric at a 45° angle; apply starch; after the starch dries completely, apply it from the right side of the fabric; then cut the piping again, and sew the bias-cut piping strips to the edges of the collar, placket, sleeves, and slits of the cheongsam to the required width; Attaching Chinese knot buttons: Sew the prepared Chinese knot buttons to the placket according to the design position. Hemming: Sew the body of the garment to the lining at the edges.

[0037] Specifically, in step S6: 3D ironing: This includes shaping and fixing, ironing the seams, and finishing the surface. Finishing the surface: Iron along the outline of the cheongsam, and avoid pressing directly on the piping and buttons. Final quality inspection: Check whether the overall shape of the garment conforms to the design; whether the stitching is firm and even; whether the size is consistent with the final design; the structure of the buttons and piping; and whether the cleanliness meets the standards.

[0038] In summary, this application improves the efficiency of pattern making by using body measurements as the basis for garment pattern making, always relying on actual human body measurements and analyzing body shape. Furthermore, the cutting device set in the cutting process can reduce the problem of fabric wrinkles during cutting, ensuring cutting efficiency and quality. Therefore, this application eliminates cumbersome cutting formulas and time-consuming draping, saving time and energy, especially for personalized custom clothing.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
