Description

Technical Field

[0001] This invention relates to the field of garment pattern technology, and in particular to a method for pattern making of underwear prototypes. Background Technology

[0002] Current underwear pattern making technology is basically based on the transformation of a trouser prototype. On the basis of the trouser prototype, the ease allowance is reduced and the dart allowance is transformed. On this basis, the basic underwear pattern can only be formed through the experience of technicians and multiple tests. It requires a high level of experience. Current draping generally uses draping white fabric, which is attached to the surface of the dress form with pins. After trimming, a basic prototype is obtained. Because the fabric has no elasticity, the resulting basic prototype will have many irregular darts. A lot of processing is required later to obtain a perfect and usable basic pattern. This requires a high level of experience and ability from the operators.

[0003] Therefore, there is an urgent need for a method that can reduce the difficulty for operators, make the pattern-making process quick and simple, and is suitable for making patterns for underwear prototypes. Summary of the Invention

[0004] The purpose of this invention is to provide a method for pattern making of underwear prototypes, which solves the technical problems of high experience requirements and difficult operation in existing underwear pattern making techniques. The various technical effects of the preferred solutions among the many technical solutions provided by this invention are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The present invention provides a method for pattern making of underwear prototypes, comprising the following steps: Step 1: Prepare a sealed heat shrink bag, a heat gun, and a mannequin. Cut three slits in the heat shrink bag to form a thick pair of trousers. Put the thick pair of trousers on the mannequin. Step 2: By manually operating the hot air gun, hot air is blown onto the thick pants shape. The thick pants shape shrinks evenly after being heated and fits into the mannequin, forming a shrinkable pants shape. Step 3: Draw a label line on the surface of the shrink-fit pants, remove the shrink-fit pants, and cut along the label line to form a preliminary sample; Step 4: Scan the initial sample into the computer, then import it into the pattern making software, and adjust the lines of the initial sample to form a sample image; Step 5: Add cutting allowance to the sample to form a cut piece, print out a paper pattern using a computer, and cut the fabric according to the paper pattern; Step 6: Sew the cut fabric together and put it on the mannequin for observation.

[0006] Preferably, in step one, there is a gap between the thick trousers and the waist and hip positions of the mannequin. The pinching edges on both sides of the thick trousers are pinched to make the thick trousers fit snugly against the waist and hip positions of the mannequin. The pinching edges on both sides are folded along the edge line of the mannequin to form a folded fitting area, and the folded fitting area is adhered to the surface of the thick trousers.

[0007] Preferably, the two sets of pinching edges on the thick trouser shape are symmetrically arranged, and the distance between the pinching edge and the edge line is 5cm-7cm.

[0008] Preferably, in step two, the temperature of the hot air gun is set to a low setting, the distance between the air outlet of the hot air gun and the wide-leg pants is controlled, the blowing time is controlled according to the degree of shrinkage of the wide-leg pants, and the position of the folds of the wide-leg pants during the shrinkage process is manually adjusted.

[0009] Preferably, in step three, before drawing the label line, the uniformity of the fit between the shrink-fit pants and the mannequin is checked.

[0010] Preferably, in step three, the label lines are drawn according to the characteristics of the mannequin.

[0011] Preferably, in step three, the initial sample includes a front sheet, a side sheet, and a back sheet.

[0012] Preferably, in step four, after the initial sample is traced, it is scanned into a DXF file by a computer, the DXF file is imported into the pattern-making software, and the pattern-making software is used to adjust it into symmetrical, complete and smooth lines to form the sample.

[0013] Preferably, in step four, the sample includes a modified front sheet, a modified side sheet, and a modified base sheet. The modified base sheet is formed by adding compensation to the edge of the base sheet to achieve the same degree of shrinkage. Based on the characteristics of the mannequin, a slack is added to the lower end of the front sheet to form the modified front sheet.

[0014] Preferably, in step five, the cutting includes shrinkage and seam allowance.

[0015] In the technical solution provided by this invention, a thick pant shape made of heat-shrink bag is placed on a mannequin. A heat gun is used to heat and shrink the pant shape, making it fit snugly against the mannequin. A preliminary pattern is cut according to the label lines. After scanning the preliminary pattern, the lines are adjusted and allowances are added using pattern-making software. Finally, the cut pieces are printed. The fabric is then cut based on the cut pieces, sewn together, and placed on the mannequin. This application offers fast preliminary pattern creation and flexible cut piece production for mannequins of different sizes.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0020] refer to Figure 1-9 A specific embodiment of the present invention provides a method for pattern making of underwear prototypes, comprising the following steps: Step 1: Prepare a sealed heat shrink bag, a heat gun, and a mannequin 2. Cut three openings in the heat shrink bag to form a thick pair of pants 1. Put the thick pair of pants 1 on the mannequin 2. Step 2: By manually operating the hot air gun, hot air is blown towards the thick pants shape 1. After the thick pants shape 1 is heated and shrinks evenly, it fits into the mannequin 2 to form the shrink pants shape 15. Step 3: Draw label line 7 on the surface of the shrink-fit pants 15, remove the shrink-fit pants 15, and cut along the label line 7 to form a preliminary sample; Step 4: Scan the initial sample into the computer, then import it into the pattern making software, adjust the lines of the initial sample to form a sample image; Step 5: Add 14mm of cutting allowance to the sample to form a cut piece. Print out a paper pattern using a computer and cut the fabric according to the paper pattern. Step 6: Sew the cut fabric together and wear it on mannequin 2 for observation.

[0021] Current underwear pattern making technology basically involves modifying a trouser prototype, reducing ease allowances and converting darts, and requiring experienced technicians and multiple tests to create the basic underwear pattern, demanding a high level of expertise. Current draping generally uses raw fabric, attaching it to a dress form with pins, and trimming to obtain the basic prototype. Due to the lack of elasticity in the raw fabric, the resulting basic prototype often contains many irregular darts, requiring extensive processing to obtain a perfect, usable pattern, demanding high levels of experience and skill from the operators. In this application, a thick trouser shape 1 made using heat-shrink bags is placed on a dress form 2. The thick trouser shape 1 is heated and shrunk using a heat gun, allowing it to fit snugly onto the dress form 2. A preliminary pattern is cut according to label line 7, scanned by computer, and adjusted using pattern-making software, with additional allowances added (14). Finally, the pattern piece is printed. The fabric is then cut based on the pattern piece, sewn together, and placed on the dress form 2. In this application, for different sizes of mannequins 2, the initial sample formation speed is fast, the fabrication of cut pieces is flexible, the whole process is quick and simple, it is suitable for the pattern design of intimate apparel, and the difficulty of operation for operators is effectively reduced.

[0022] Further optimizing the design, in step one, there is a gap between the waist and hip positions of the thick trousers 1 and the mannequin 2. The pinching edges 3 on both sides of the thick trousers 1 are pinched to make them fit snugly against the waist and hip positions of the mannequin 2. The pinching edges 3 on both sides are folded along the edge line 4 on the mannequin 2 to form a folded fitting area 6, which is then adhered to the surface of the thick trousers 1. The two sets of pinching edges 3 on the thick trousers 1 are symmetrically arranged, with the distance between the pinching edges 3 and the edge line 4 being 5cm-7cm.

[0023] After the thick pants 1 are put on the mannequin 2, there is a gap between them, meaning that the thick pants 1 has a lot of extra fabric. On both sides of the mannequin 2, pinch the pinching edges 3 on both sides of the thick pants 1, pinching off 6cm on each side of the thick pants 1. That is, the distance between one side of the thick pants 1 and the edge line 4 on the mannequin 2 is 6cm, so that the thick pants 1 fits the surface of the mannequin 2 as closely as possible, achieving a close fit between the thick pants 1 and the waist and hip areas of the mannequin 2. Next, fold the pinching edges 3 around the edge line 4 to form a folded fitting area 6, and then stick the folded fitting area 6 to the surface of the thick pants 1. This process is to speed up the shrinkage of the thick pants 1 when hot air is blown on it, and to ensure a good fit between the thick pants 1 and the mannequin 2. The thick pants 1 near the legs of the mannequin 2 also need to be folded and stuck to ensure a good fit between the thick pants 1 and the legs of the mannequin 2, achieving a preliminary fit.

[0024] To further optimize the solution, in step two, the temperature of the hot air gun is set to low speed, the distance between the air outlet of the hot air gun and the thick trousers 1 is controlled, the blowing time is controlled according to the degree of shrinkage of the thick trousers 1, and the position of the folds of the thick trousers 1 during the shrinkage process is manually adjusted.

[0025] After the trousers 1 and the mannequin 2 are initially fitted together, set the temperature of the heat gun to 300℃ and adjust the airflow to low. Keep the distance between the heat gun and the trousers 1 at 20cm. During the heating process, slightly increase the blowing time for areas with loose areas. For areas with more pleats, you can use your hands to gently separate them while blowing air to better control the heat shrink bag to shrink evenly.

[0026] To further optimize the plan, in step three, before drawing the label line 7, check the uniformity of the fit between the shrink-fit pants 15 and the mannequin 2.

[0027] If there is a significant gap or uneven fit between the shrink-fit pants 15 and the mannequin 2, use a heat gun to heat and adjust it.

[0028] To further optimize the plan, in step three, label lines 7 are drawn based on the characteristics of mannequin 2.

[0029] The mannequin 2 features both male and female characteristics, meaning the label lines 7 are drawn based on these gender characteristics. In this application, male characteristics are used as an example. Reference lines 5 are drawn on the surface of the mannequin 2 as a reference and benchmark for drawing the label lines 7.

[0030] Further optimization of the plan: In step three, the initial sample includes front film 8, side film 9, and negative film 10.

[0031] To further optimize the scheme, in step four, after the initial sample is rubbed, it is scanned into a DXF file by computer. The DXF file is then imported into the pattern-making software, which adjusts it to create symmetrical, complete, and smooth lines to form a sample.

[0032] After making the initial print, scan it into the computer as a DXF file. Import the DXF file into the dedicated pattern-making software and adjust the smoothness of the lines. Based on the left-right completeness of the graphic, adjust the left-right symmetry of each pattern piece. For example, the first center line 11 and the second center line 13 will serve as reference lines for correcting the left-right symmetry of the side piece 16 and the base piece 18, respectively.

[0033] Further optimization of the scheme: In step four, the sample includes a modified front sheet 17, a modified side sheet 16, and a modified bottom sheet 18. Compensation is added to the edge of the bottom sheet 10 to form the modified bottom sheet 18. Based on the characteristics of the mannequin 2, a slack is added to the lower end of the front sheet 8 to form the modified front sheet 17.

[0034] Two sets of excess seam lines 12 are cut at the lower end of the front piece 8 to form the corrected front piece 17. When the two sets of excess seam lines 12 are sewn together, they form a protruding style that conforms to male characteristics. The back piece 10 shrinks in the middle due to the heat shrinkage of the thermoplastic bag. When processing computer data, the amount of shrinkage in the middle needs to be released and adjusted to form the corrected back piece 18.

[0035] Further optimize the plan. In step five, the cutting measurement 14 includes reduction and seam allowance.

[0036] Based on the adjusted sample, and taking into account the fabric's elasticity, add appropriate shrinkage and seam allowances to extract the cut pieces. Print the cut pieces from the computer and cut the fabric according to the printed pattern. Sew the cut fabric together and wear it on a person for observation. Adjust the lines of the cut pieces flexibly according to any deviations.
