Description

Technical Field

[0001] The invention belongs to the technical field of clothing, and in particular relates to a three-dimensional skirt design method using a three-dimensional structure. Background Art

[0002] The commonly used pattern making methods for clothing are divided into two categories: flat pattern making and three-dimensional cutting. These two types of pattern making methods rely more on the operator's experience, and it takes a lot of time to systematically learn the knowledge of pattern making. The styles of the clothes made are fixed. On the other hand, flat pattern making is suitable for conventional clothing, but not for clothing with three-dimensional modeling effects, and it produces more waste fabrics. This type of clothing is suitable for creation through three-dimensional cutting, and three-dimensional cutting is a three-dimensional creation technology that relies on a mannequin and is different from conventional flat cutting. During the whole process, the designer needs to mobilize hands, brains, and eyes to interact with each other. After conception, modeling, modification, and even repeated modification, the designer can obtain a work that satisfies or is infinitely close to satisfaction. In this process, more fabric waste will also be generated. In short, the existing methods for creating three-dimensional clothing rely more on the operator's experience, and it takes a lot of time to systematically learn the knowledge of pattern making. The styles of the clothes made are fixed. Under the current fast and short-lived fashion trend, clothing has been seriously discarded. Whether it is the plate making process or the clothing discarding process, it causes a large waste of fabrics and pollutes the environment. Summary of the invention

[0003] The purpose of the present invention is to provide a three-dimensional skirt design method which is simple to learn, has little fabric waste, and has a variety of styles, thereby promoting the development of sustainable design and reducing damage to the environment.

[0004] In a first aspect, the present invention provides a three-dimensional skirt design method using a regular polyhedron structure, comprising the following steps: Step 1: Cut the fabric into polygons identical to the unfolded image of the regular polyhedron, and use the cut polygonal fabric to form a regular polyhedron; select any edge of the regular polyhedron as the skirt edge, and sew the open edges of the regular polyhedron except the skirt edge.

[0005] Step 2, making front and back top samples; placing the front and back top samples on two adjacent sides of the opposite sides of the skirt on the regular polyhedron, and the necklines of the front and back top samples are both facing the opposite sides of the skirt; connecting the waist points of the front top sample and the back top sample, and cutting and removing the area between the outline lines of the front and back top samples and the waist point connection line as a negative area to form the front and back pieces.

[0006] Step 3: Fit the front piece and the back piece together, and sew the shoulder line and the side seam to form the top; the area outside the top forms the skirt. Sew the openings on both sides of the skirt to obtain a skirt with a three-dimensional structure. The openings on both sides of the skirt are formed by the waist point connection line in step 2.

[0007] Preferably, in the step 1, the polygonal fabric is obtained by integral cutting, and a skirt is selected on the edge of the polygonal fabric.

[0008] Preferably, in step 1, the polygonal fabric is obtained by splicing a plurality of fabric blocks, and different fabric blocks are made of the same or different fabrics.

[0051] The present invention will be further described below in conjunction with the accompanying drawings.

[0052] Example 1 A three-dimensional skirt design method using a three-dimensional structure uses a cubic structure for three-dimensional modeling design, comprising the following steps: Step 1: Figure 1 As shown, three fabrics of different colors and matching are selected, and each of the three fabrics is cut into two 70cm×70cm squares; the six square fabrics cut out are arranged according to the positions of the cube expansion diagram, and are numbered in the order of 1 to 6, where 1 and 5, 2 and 3, 4 and 6 are squares cut out of the same fabric. In this embodiment, the three selected fabrics are off-white four-way stretch fabric, light pink polyester taffeta fabric and patterned artificial cotton silk fabric. These three fabrics are light, breathable, smooth and drapey, ensuring the close-fitting comfort of the garment, and the color matching is beautiful.

[0053] Step 2: Figure 2 As shown, the edge where fabric 4 and fabric 6 intersect is retained as the skirt edge, and the remaining edges are sewn, that is, the six square fabrics are sewn into a cube, among which 1 and 6, 2 and 4, and 3 and 5 are opposite to each other respectively; a three-thread overlock sewing machine is used to overlock all the seams, and finally a cube effect is presented.

[0054] Step 3: Figure 3As shown, make the front and back top samples according to the 160 / 84A women's table size, place the front and back top samples on the cube-shaped fabric 2 and fabric 1 respectively, with the neckline of the top sample facing the intersection of fabric 2 and fabric 1; and place the front top sample at the middle right of fabric 2, and the back top sample at the lower left of fabric 1. Draw the outline according to the edge of the top sample, and connect the waist points of the front top outline and the back top outline with irregular curves.

[0055] Step 4: After leaving the seam allowance, cut out the area between the front and back top pattern outline and the waistline as the negative area to form the front and back pieces. Fit the front and back pieces together, and sew the shoulder and side seams to form the top; the area outside the top forms the hem. Sew up the openings on both sides of the hem formed by the waistline, leaving the right side seam open, and install the zipper. Overlock the seam allowance, and hem the neckline and sleeve line to get a loose spliced ​​vest long skirt, such as Figure 4 This long skirt has an irregular three-dimensional skirt, which cannot be achieved by using ordinary flat pattern making method or conventional three-dimensional cutting method.

[0056] Example 2 A three-dimensional skirt design method using a three-dimensional structure. The difference between this embodiment and embodiment 1 is that after step 4 is executed, on the obtained loose spliced ​​vest long skirt, avoid the private parts of the human body and select appropriate positions for digging holes. In this embodiment, the diameter of the holes is 8cm and 10cm, respectively designed at the left and right waist positions of the front piece, the back waist position, and the hem position, with asymmetrical distribution of height. All the holes are hemmed and beige ribbons are inserted to tighten and create a pleated effect. The finished product is ironed to obtain a breathable drape vest long skirt. Figure 5 As shown in the figure, the long skirt not only increases the convection of the human body and has the function of cooling and ventilation, but also shows the beautiful figure of the wearer and has sexy style characteristics. Due to the hole and ribbon design, the skirt can be freely matched according to the wearer's personal preferences, and a variety of styles can be converted at will. The skirt includes the following styles:

[0057] Style 1: Waist-length pleated skirt like Figure 6 As shown, tighten the drawstrings at some or all of the openings; the pleats at the waist have a slimming effect, the pleats at the hem make the skirt more layered, the ribbon adds a flowing effect to the skirt, and the overall hem is short in front and long in the back, which conforms to the aesthetics of the human body.

[0058] Style 2: Waist-hugging pleated multi-layered short skirt like Figure 7 As shown, tuck the excess fabric on both sides of the skirt into the holes and tie them tightly, then tie them with the remaining holes to change the overall skirt from long to short.

[0059] Style 3: Waist-length pleated skirt like Figure 8 As shown, by changing the way the holes are tied, the skirt is changed from long to medium-length, giving it a more layered look.

[0060] Style 4: Waist-pleated cake skirt like Fig. 9 As shown, by changing the holes and tying the knots, the long skirt is changed to a short one, the front and back hems are close in length, the hems are more layered, and it has a Lolita style.

[0061] Example 3 A three-dimensional skirt design method using a three-dimensional structure uses a regular tetrahedron structure for three-dimensional modeling design, comprising the following steps: Step 1: Fig.10 As shown, three fabrics with different colors are selected, namely, off-white four-way stretch fabric, light pink polyester taffeta fabric and patterned artificial cotton silk fabric. These three fabrics are light, breathable, smooth and drapey, ensuring the comfort of close-fitting clothing. The three fabrics are cut into equilateral triangles of the same size, two pieces of light pink polyester taffeta fabric are cut, and one piece of the other fabrics is cut. The side length of the equilateral triangle fabric is 46cm; the four equilateral triangle fabrics are arranged according to the position of the regular tetrahedron expansion diagram and numbered in the order of 1 to 4, where 1 and 4 are equilateral triangles cut from the same fabric.

[0062] Step 2: Keep the intersecting edge of fabric 4 and fabric 6 as the skirt edge, and sew the remaining edges, that is, sew the four equilateral triangle fabrics into a cube; use a three-thread overlock sewing machine to overlock all the seams.

[0063] Step 3. Make front and back top samples according to the size of 1 / 2 mannequin, and place the front and back top samples on fabric 2 and fabric 3 respectively, with the necklines of the front and back top samples facing the intersection of fabric 2 and fabric 3; draw the outline according to the edge of the sample, and use irregular curves to connect the waist points of the front top outline and the back top outline.

[0064] Step 4: Fig.11 As shown, after leaving the seam allowance, the area between the front and back top pattern outline and the waist point connection line is cut and removed as the negative area to form the front and back pieces. The front piece is fitted with the back piece, and the shoulder line and side seam line are sewn to form the top; the area outside the top forms the skirt. The openings formed by the waist point connection line on both sides of the skirt are sewn, leaving the right side seam, and the zipper is installed. All seams are overlocked, and the finished product is ironed to obtain a triangular draped skirt. The skirt has natural triangular drapes at the waist, which are stacked on the left and right sides of the skirt body. The left and right sides have more drapes and the other has less drapes, which is full of design sense, and the skirt length is moderate, which can meet the wearer's daily activities.

[0065] Example 4 A three-dimensional skirt design method using a three-dimensional structure. The difference between this embodiment and embodiment 3 is that buttons are added to the excess fabrics on the left and right waists. The skirt has two switchable styles, as follows: Style 1: Multi-layered hip skirt like Fig.12 As shown, fabric 3 is overlapped to the front piece and connected by buttons, and fabric 4 is overlapped to the back piece and connected by buttons. The triangular fabric at the waist adds a decorative effect to the skirt, while the front and back side fabrics enrich the layering of the skirt.

[0066] Style 2: Multi-pleated short skirt like Fig.13 As shown, fabric 4 is overlapped to the front piece and connected by buttons, and fabric 3 is overlapped to the back piece and connected by buttons; after fabric 4 is overlapped to the front piece, an apron-like style is obtained, and the back side fabric forms a small decoration at the waist.

[0067] By overlapping the excess fabric with the front and back pieces, the presence of fabric between the skirt is reduced, making the style look cleaner and more design-oriented than ordinary pencil skirts.

[0068] Example 5 A three-dimensional skirt design method using a three-dimensional structure, specifically using a cylinder for three-dimensional modeling design, includes the following steps: Step 1: Fig.14 As shown, two fabrics of different colors are selected, namely red pure cotton fabric and brown plaid woolen fabric. Cut the two fabrics into rectangles of 150cm×93cm respectively; the two rectangular fabrics correspond to the side of half of the cylinder respectively; overlap and stick the two cut rectangles together, sew the long sides of the two overlapping rectangles and any one of the overlapping wide sides, and perform overlocking on the seam allowance.

[0069] Step 2: Fig.15 As shown, make front and back top patterns according to the 160 / 84A women's table size, and place the front and back top patterns on any rectangular fabric so that the front and back top patterns are opposite to each other and placed obliquely on the diagonal of the rectangle; draw the outline according to the edge of the pattern, and connect the waist points of the front top outline and the back top outline with irregular curves.

[0070] Step 3: As shown in Figure 16, after leaving the seam allowance, cut and remove the area between the front and back top pattern outline and the waist point connection line as the negative area to form the front and back pieces. Fit the front and back pieces together, and sew the shoulder line and side seams to form the top; the area outside the top forms the skirt.

[0071] Step 4: Fig.17As shown, all seams are overlocked, and the finished product is arranged and ironed to obtain a long skirt with a waist and draped pleats and a large hem. The skirt hangs naturally, the hem is pleated, and there are multiple layers of fabric at the back waist. The two colors of fabric form a contrast, giving the skirt a multi-layered effect.

[0072] Example 6 A three-dimensional skirt design method using a three-dimensional structure, specifically using the side of a cylinder for three-dimensional modeling design, includes the following steps: Step 1: Fig.18 As shown, two fabrics of different colors are selected, namely, off-white four-way stretch fabric and patterned artificial cotton fabric. The two fabrics are cut into rectangles of 50cm×100cm respectively; the two rectangular fabrics correspond to the side of half of the cylinder respectively; the two cut rectangles are attached together, and the long sides of the two rectangles overlap are sewn, and the seams are covered to form a cylinder.

[0073] Step 2: Fig.19 As shown, make front and back jacket patterns according to the size of 160 / 84A mannequin, and place the front and back jacket patterns on two rectangular fabrics respectively, with the front and back jacket patterns facing each other; draw the outline according to the edge of the pattern, and connect the waist points of the front jacket outline and the back jacket outline with irregular curves.

[0074] Step 3: After leaving the seam allowance, cut out the area between the front and back top pattern outline and the waist point connection line as the negative area to form the front and back pieces. Fit the front and back pieces together, and sew the shoulder and side seams to form the top; the area outside the top forms the hem; for the sake of convenience in display, the two overlapping fabrics are laid flat in Figure 16. In fact, the two are still Fig.15 The stitching status shown in .

[0075] Step 4: Fig. 20 As shown, all seams are overlocked, the finished product is trimmed and ironed, and the excess fabric at the waist is wrapped around the waist to form a long skirt with a belt and an intellectual and elegant style; if the belt is tied forward, a long skirt with a white front and a floral knot at the waist is formed, such as Fig.21 As shown; if the belt is tied backwards, the front piece will be pure white, the back piece will be mainly floral, and the waist will be decorated with a knot of alternating white and floral patterns, such as Fig. 22 In the style shown, the knot has both decorative effect and waist-tightening function.

[0076] Example 7 A three-dimensional skirt design method using a three-dimensional structure. The difference between this embodiment and embodiment 6 is that after step 4 is executed, holes are dug at appropriate locations on the obtained loose spliced ​​vest long skirt, avoiding the private parts of the human body. All holes are hemmed and green ribbons are inserted. Due to the hole and ribbon design, the skirt can be freely matched according to the wearer's personal preferences, and multiple styles can be converted at will. The skirt includes the following styles:

[0077] Style 1: Straight-tube long skirt like Fig.23 As shown in the figure, tie the green ribbon tightly and adjust the tightness of the ribbon, which can not only adjust the bust, waist and hem size, but also adjust the diameter of the hole after tying, thereby adjusting the breathability of the long skirt, achieving the effect of killing two birds with one stone. For example, when the weather is hot, you can tie the ribbon slightly to leave larger holes for ventilation. At this time, the waist, bust, hips, hem and other parts are looser, which can also play a role in convection heat dissipation. When the temperature is low, you can tighten the ribbon to form a closed area to reduce the loss of heat from the human body.

[0078] Style 2: Pleated ribbon long skirt like Fig.24 As shown, the corresponding holes when folded are tied opposite to each other; this style is similar to the ancient Greek toga (toga robe), with a unique artistic effect. At the same time, the added holes and ribbons allow the style to be freely matched according to the wearer's preferences, and the length, style and looseness of the skirt can be flexibly changed to meet the needs of different weather and occasions.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. That is, all equivalent changes and revisions made according to the content of the patent application scope of the present invention are within the technical scope of the present invention.
