[0031] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0033] Please refer to this as well. Figures 1 to 7 This invention provides a method for cutting a suit from a single piece of fabric, including:

[0034] S10, Obtain the entire piece of fabric;

[0035] S20. Determine the middle preset range of the entire piece of fabric as the collar outline cutting area Z1; determine the lapel lining cutting area Z2 extending from the collar outline cutting area Z1 to the edge of the entire piece of fabric; determine the shoulder and back cutting area Z3 located in the collar outline cutting area Z1 opposite to the lapel lining cutting area Z2 and the front hem cutting area Z4 connecting the shoulder and back cutting area Z3; determine the sleeve cutting area Z5 located on both sides of the collar outline cutting area Z1 and the lapel lining cutting area Z2 and the front piece cutting area Z6 connecting the sleeve cutting area Z5; cut according to the cutting lines corresponding to the collar outline cutting area Z1, the lapel lining cutting area Z2, the shoulder and back cutting area Z3, the front hem cutting area Z4, the sleeve cutting area Z5 and the front piece cutting area Z6, remove excess fabric, and obtain the cut fabric.

[0036] S30, fold the cutting fabric at the joint of the collar contour cutting region Z1 and the shoulder back cutting region Z3, fold and sew the sleeve cutting region Z5 to form a sleeve, sew the shoulder back cutting region Z3 corresponding to the sleeve cutting region Z5 to form an armhole, fold the front lower hem cutting region Z4 and sew it corresponding to the front piece cutting region Z6 to obtain a one-piece suit; the sewing includes fixed sewing or movable sewing.

[0037] Further, in the preferred embodiment, the shape of the whole piece of fabric is approximately circular.

[0038] Specifically, in the embodiment, the circular whole piece of fabric adopts a fabric with a diameter of 1.45m. It can be understood that the size of the whole piece of fabric can also be adjusted according to the needs of different user body types, such as a fabric with a diameter of 1.4m, a fabric with a diameter of 1.5m, etc. The one-piece suit is made by folding and cutting the circular whole piece of fabric, and the process is highly standardized and efficient. Specifically, the radius of the whole piece of fabric is approximately equal to the target length of the suit, for example, to make a suit with a target length of 0.72m, the radius of the circular whole piece of fabric can be 0.72m plus or minus a preset amount, for example, 0.7m-0.74m, and the diameter of the fabric is 1.4m-1.48m.

[0039] In the embodiment, the circular fabric is used to make a suit. It can be understood that after the above-mentioned manufacturing process, the edge of the circular whole piece of fabric corresponds to form the edge area of the lower hem edge, the sleeve cuff, etc. of the suit, achieving the purpose of direct clothing making, further simplifying the manufacturing process and improving the manufacturing effect. It can be understood that in other embodiments, considering the different body types of users, the relative size and position of each region will be different according to the above-mentioned steps, so that the shape of the whole piece of fabric cannot be completely limited to circular, and can also be elliptical, square, irregular, etc. For example, for the needs of large-volume users, the corresponding shoulder back cutting region Z3 needs to be increased in width, and correspondingly, the sleeve cutting region Z5 needs to be moved outward, so the cutting region of the whole piece of fabric will extend outward by a part, so that the whole piece of fabric needs to be cut and made within an approximately elliptical shape. It can be understood that a square whole piece of fabric or other irregular whole piece of fabric can also meet the clothing making needs, and the excess edge fabric can be cut and removed based on the above-mentioned cutting steps.

[0040] In step S20, the dimensions of the corresponding areas are cut to match the body size of the target user. For example, the collar outline cutting area Z1 corresponds to the neck size and shape of the target user, satisfying the matching neck shape and having a certain amount of ease; the shoulder and back cutting area Z3 corresponds to matching half of the chest size of the target user, such as using half the chest size + 2cm as the width of the shoulder and back cutting area Z3; the width of the sleeve cutting area Z4 corresponds to the sleeve width of the target user, and the length corresponds to the arm length of the target user, and so on.

[0041] In step S30, the corresponding area can be sewn with a fixed stitch to form a non-removable one-piece suit; or it can be sewn with a zipper, button, hook, or other movable stitching.
