Abstract
Description
Technical Field
[0001] This invention relates to the field of clothing technology, particularly to the field of IPC A41D1, and further to the process and manufacturing method of trousers for flat-hipped and hip-down body types. Background Technology
[0002] With the development of the social economy, people's demand for spiritual and cultural enrichment is also increasing as their living standards improve. In the clothing industry, more and more fashion-conscious women are pursuing personalized and aesthetically pleasing clothing while also placing higher demands on the fit of their garments. The fit of trousers, in particular, is closely related to body shape; those with flat hips or a low hip point require trousers with a more structured design.
[0003] Chinese patent CN201420340450 discloses a buttock-lifting and body-shaping system, including shaping pants and a buttock-shaping pad. The shaping pants have a pad bag on the back, and the buttock-shaping pad is inserted into the pad bag through the opening. The buttock-shaping pad is made of a foam layer and a silicone layer bonded together with hot melt adhesive. The silicone layer is 1mm thick, and the edge of the foam layer is 5mm smaller than the edge of the silicone layer, so that the silicone layer completely covers the foam layer, and the foam layer is a one-piece design. This technical solution combines shaping pants and a buttock-shaping pad to improve the buttock curve of women with flat or small buttocks, increasing women's confidence. However, the buttock-shaping pad is prone to deformation after repeated washing, which is unsightly.
[0004] Chinese patent CN201620640415 discloses a type of tight-fitting, cropped, hip-lifting trousers, comprising two front panels of identical shape and structure, two back panels of identical shape and structure, a front waistband, a back waistband, a fly, and two yokes of identical shape and structure. The length of the front panels is shorter than the length of the back panels. The waistline of the human body is located at half the length of the back waistband. The upper end of the back panels is curved, and its outer upper portion has pleats. The lower end of the yokes has an arc-shaped structure that matches the arc shape of the upper end of the back panels. The back of the back panels has longitudinal darts corresponding to the buttocks. The sewn-up back panels give the buttocks a three-dimensional feel. However, this technical solution is designed for tight-fitting jeans, and its application range is relatively narrow. Summary of the Invention
[0005] To solve the above-mentioned technical problems, the present invention provides a trouser design process for flat-hipped and lower-point-of-hip body types, including the following steps:
[0006] (1) Design the back and front trouser pieces of the required size and shape;
[0007] (2) Cut out the semi-finished back trouser piece and draw the waistline AB, hipline CD, crotch line EF, crotch line GH, and back center seam line JK;
[0008] (3) Determine the hip height point and the position of the dart on the back trouser piece, and draw the length of the dart;
[0009] (4) Cut, reassemble, and collect the province along the provincial border;
[0010] (5) The back trouser pieces are straightened and pulled back;
[0011] (6) Sew the back trouser piece and the front trouser piece together.
[0012] In some preferred embodiments, the hip height point is located at a position of 0.2 to 0.4 cm from the endpoint C of the hip circumference line.
[0013] Preferably, the hip height point is located at a position L, 0.3 cm from the end point of the hip circumference line C.
[0014] In some preferred embodiments, a first longitudinal dart is provided on the back trouser piece between the waistline and the hipline.
[0015] Preferably, the first province is triangular in shape.
[0016] Preferably, the midline of the triangle is: the midline of the triangle is the line connecting the hip height point L and the crotch point M and extending to the waistline.
[0017] In some preferred embodiments, the length of the first province is 9 + (0.1~2) cm.
[0018] Preferably, the length of the first province is 9 + (1~2) cm.
[0019] Preferably, the length of the first province is 9 + 1.5 cm.
[0020] In some preferred embodiments, a second longitudinal dart is provided on the back trouser piece between the hip line and the crotch line.
[0021] Preferably, the second province is located at the junction of the end point of the hip line C and the end point of the crotch line G.
[0022] Preferably, the edge line of the second province is: the intersection of the end point of the hip line C and the end point of the crotch line G with the upper crotch line EF is denoted as N, and a point is taken on EN and FN respectively and denoted as O and P. Connecting CO, OG, GP and PC is the edge line of the second province.
[0023] In some preferred embodiments, the distance of the second section after EP is 1 / 10 of the hip circumference + (0.1~1) cm.
[0024] Preferably, the distance of the second province after the EP is collected is 1 / 10 of the hip circumference + (0.5~1)cm.
[0025] Preferably, the distance of the second province after the EP is 1 / 10 of the hip circumference + 1cm.
[0026] In some preferred embodiments, the specific method of step (4) is as follows: cut along the edge line of the second dart, and fix the cut piece with the dart piece and the trouser piece; cut along the edge line of the first dart, and assemble the cut pieces and tuck them in.
[0027] Preferably, the overlap of the cut pieces from the second province is transferred to the rear inner crotch.
[0028] In some preferred embodiments, the specific method of step (5) is as follows: first, pull the back inner crotch area, then pull the upper end of the inner crotch seam, and finally pull the inner crotch.
[0029] Preferably, the temperature of the calcination is 160–180°C.
[0030] Preferably, the temperature of the tube is 170°C.
[0031] In this application, the applicant, through extensive creative experimental research, discovered that designing a first and second dart in the trouser manufacturing process, controlling the length of the first dart to 9 + (1~2) cm, and transferring the overlap of the second dart cut and spliced to the back crotch effectively solves the problem of women with flat hips or a lower hip point experiencing gaps in the middle of the hips and slanted lines at the root of the back thighs when wearing trousers. It also avoids tightness. Combined with the subsequent shaping process, on the one hand, it makes the width and size of the back crotch seam suitable for women with flat hips or a lower hip point, making the hips, waist, and legs fit the human body better and achieving a buttock-lifting effect; on the other hand, it also avoids the problem of being unable to sew due to a large difference in length between the inner seam of the back trouser piece and the inner seam of the front trouser piece.
[0032] In some preferred embodiments, the crotch is straightened during the stitching process in step (6).
[0033] In some preferred embodiments, the back and front trouser panels are made of woven fabric or 30-70% wool.
[0034] Beneficial effects:
[0035] 1. This application has a first vertical dart on the back pant piece located between the waistline and the hipline. The length of the first dart is controlled to be 9+(1~2)cm, which can effectively solve the problem of mid-hip gap in women with flat hips and lower hip point.
[0036] 2. This application features a second vertical dart on the back panel, located between the hip line and the crotch line. The overlap of the cut pieces of the second dart is transferred to the back inner crotch, increasing the width of the back inner crotch. This effectively solves the problem of slanted creases at the root of the thighs for women with flat hips or a downward shift in the hip point.
[0037] 3. This application controls the distance of EP after the second province is collected to be 1 / 10 of the hip circumference + (0.5~1)cm, which not only solves the problem of crotch pinching and wrinkles in women with flat hips and lower hip point, but also improves the fit between the pants and the human body.
[0038] 4. The pull-out process of this application, on the one hand, makes the width of the back crotch and the size of the crotch seam suitable for women with flat hips and lower hip points, so that the hips, waist and legs fit the human body more closely and achieve the effect of lifting the hips; on the other hand, it can also avoid the problem that the length difference between the inner seam of the back pant piece and the inner seam of the front pant piece is too large to sew.
[0039] 5. The temperature of the trousers is controlled at 160-180℃, which can effectively adjust the shape of the trousers and avoid damage to the material of the trousers. Attached Figure Description
