Abstract

The invention relates to a method for eliminating rear inclined locks of trousers, which comprises the following steps of: S1, cutting a rear cut piece IJHXY into a rear upper cut piece IJHBA and a rear lower cut piece B1XYA1 along a knee circumference line AB, and horizontally moving the rear lower cut piece B1XYA1 towards a trousers inner sewing line HX by 0.8-1.2 cm; s2, lengthening the width of the rear crotch bend, and correcting the inclination of the rear cut-part of the trousers; s3, re-determining the trouser center line and adjusting the hip circumference; according to the method, through knee circumference line segmentation and displacement of a pants rear lower cutting piece B1XYA1, the tension of a hip fabric is released, a rear crotch bend is lengthened to reconstruct a hip curved surface space, the length and the width of the rear crotch bend are lengthened, and an upward splayed inclined lock of the rear crotch is eliminated; after the trousers manufactured by the method are worn, the buttock peak at the buttocks is full, so that the trousers are more attractive and comfortable to wear, and the production efficiency is improved.

Description

Technical Field

[0001] This invention relates to a method for eliminating diagonal creases on the back of trousers, belonging to the field of garment processing technology. Background Technology

[0002] A well-fitting pair of pants is not only aesthetically pleasing and comfortable to wear, but it can also have a slimming effect. However, due to significant differences in body shape, as shown in the attached image... Figure 1 As shown, the upward slant at the crotch and buttocks of trousers not only affects the appearance but also reduces product quality. At the same time, trousers with slant are not comfortable to wear and may restrict movement. In addition, for clothing manufacturers, the slant problem may increase the defect rate, raise production costs, and affect the company's economic benefits and market reputation. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a method for eliminating the diagonal creases at the back of pants by dividing and adjusting the back panel of the pants so that the buttocks are full and flat after wearing.

[0004] The present invention adopts the following technical solution:

[0005] The present invention discloses a method for eliminating back slant lines in trousers, comprising a back panel IJHXY; AB is the knee line, CD is the center line, EF is the hip line, GH is the crotch line, and IJ is the waist line. The method for eliminating back slant lines comprises the following steps:

[0006] S1. Cut the back panel IJHXY along the knee line AB into the upper back panel IJHBA and the lower back panel B1XYA1. Move the lower back panel B1XYA1 horizontally towards the inner seam HX of the pants by 0.8cm to 1.2cm.

[0007] S2. Increase the width of the back crotch bend and correct the slant of the back panel of the pants;

[0008] S3. Redefine the center line of the pants and adjust the hip circumference.

[0009] In the present invention S1, the bottom edge of the upper back panel IJHBA is AB, and the top edge of the lower back panel B1XYA1 is A1B1; after moving, point A1 is on line AB, point B1 is on the extension line of AB, and AA1 = BB1 = 0.8cm ~ 1.2cm.

[0010] Specifically, S2 of this invention is as follows: A1E is smoothly connected by an arc, A1E intersects GH at point G1, GH is extended to point H1, GG1 = HH1, B1H1 is smoothly connected by an arc, and H1J is smoothly connected by an arc.

[0011] Specifically, S3 of this invention is as follows: take the midpoint D1 of A1B1, connect DD1 and extend it to intersect IJ at point C1; take point F1 on line FJ, the length of FF1 is 0.6cm to 0.8cm, connect EF1 with a straight line, EF1 is the new hip line;

[0012] Extend FJ to J1, with JJ1 having a length of 0.6cm to 0.8cm, and connect it to IJ1 in a straight line. IJ1 is the new waistline.

[0013] Then IJ1H1XY is the corrected back panel of the trousers.

[0014] The positive effects of this invention are as follows: By dividing the knee circumference and shifting the lower back panel B1XYA1, the method of this invention releases the tension of the buttock fabric, extends the back crotch curve to reconstruct the curvature space of the buttock, increases the length and width of the back crotch curve, and eliminates the upward V-shaped slant of the back crotch; it redefines the center line of the pants to maintain smooth leg lines and prevents the pant leg from twisting. Pants made using this method have a fuller buttock peak when worn, making the pants more beautiful and comfortable to wear, and improving production efficiency, reducing rework of finished products, and reducing fabric waste by more than 20%.

[0019] As attached Figure 2 , 3 As shown, the back panel of the trousers of this invention is IJHXY; AB is the knee line, CD is the center line, EF is the hip line, GH is the crotch line, and IJ is the waist line. The method for eliminating the slant at the back of the trousers adopts the following steps:

[0020] S1. Cut the back panel IJHXY along the knee circumference line AB into the upper back panel IJHBA and the lower back panel B1XYA1. The bottom edge of the upper back panel IJHBA is AB, and the top edge of the lower back panel B1XYA1 is A1B1. Move the lower back panel B1XYA1 horizontally towards the inner seam HX of the pants by 0.8cm to 1.2cm. In this embodiment, 1cm is optimal. After the movement, point A1 is on line AB, and point B1 is on the extension line of AB. AA1 = BB1 = 0.8cm to 1.2cm. In this embodiment, 1cm is optimal.

[0021] S2. Smoothly connect A1E with GH at point G1. Extend GH to point H1, GG1 = HH1. Smoothly connect B1H1 with GH and H1J with GH. This operation increases the width of the back crotch bend and corrects the skew of the back trousers.

[0022] S3, as attached Figure 3 , 4 As shown, take the midpoint D1 of A1B1, connect DD1 and extend it to intersect IJ at point C1, thus redefining the center line DC1 of the pants; take point F1 on line FJ, the length of FF1 is 0.6cm~0.8cm, and connect EF1 with a straight line, EF1 is the new hip line; extend FJ to J1, the length of JJ1 is 0.6cm~0.8cm, and connect IJ1 with a straight line, IJ1 is the new waist line; the back crotch curve length is increased, and the hip shape of the pants is adjusted, then IJ1H1XY is the corrected back pant piece. When wearing the adjusted pants, the hip peak is full, eliminating the upward V-shaped slant of the back crotch, making the pants more beautiful and comfortable to wear, and improving production efficiency, reducing product rework, and reducing fabric waste by more than 20%.

[0023] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
