AI Technical Summary
The placket of a pullover shirt is prone to splitting or deforming under stress, and existing technology cannot provide sufficient structural stability.
A reverse folding technique is used to create a slit at the intersection of the side and bottom edges of the placket. The fold is then reversed inward along the slit to form a folded edge. After heat pressing to create heat marks, the placket is sewn together, increasing the strength of the side and bottom triangular areas of the placket.
It improves the strength of the placket, preventing it from splitting or deforming under stress, and enhances the durability and aesthetics of the pullover shirt.

Description
Technical Field
[0001] This utility model relates to the field of clothing technology, specifically to a structure for the placket of an anti-splitting pullover shirt. Background Technology
[0002] The placket of a pullover shirt is the opening at the front of the shirt, used for easy putting on and taking off, but it also affects the shirt's appearance and durability. For example, the pullover shirt described in application number 201020514666.6 includes a shirt body with an opening at the top forming a collar; its key feature is that the shirt body is pullover style, and it has a clasp placket extending from the collar to a position on the shirt body corresponding to the chest area, changing the traditional way of wearing a shirt and making it as simple and quick to put on as a T-shirt. However, unlike traditional open-front shirts, the placket of a pullover shirt usually requires higher structural stability to prevent splitting or deformation under stress. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a ripstop pullover shirt placket structure. This placket structure is suitable for pullover shirts and improves the firmness of the sides and bottom triangular area of the placket through a reverse folding process, thus preventing the placket from splitting or deforming under stress.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] The anti-splitting pullover shirt placket structure includes a front panel fabric and a placket fabric with an opening on one side. The front panel fabric has a placket opening that extends from the neckline to the middle of the garment. The placket opening includes two side edges and a bottom edge. A slit is provided at the intersection of the side edges and the bottom edge. The side edges and the bottom edge are folded inward along the slit to form a folded edge. The folded edge is heat-pressed to form a heat mark.
[0006] The side edges are sewn to the placket fabric for the first time at a distance of 0.1cm from the heat mark. The folded edge is then folded inward along the heat mark, and the folded side edges are sewn to the placket fabric for the second time.
[0007] Preferably, the folded edge is provided with an adhesive strip with heat-pressing points, and the folded edge is bonded to the front fabric by heat pressing, and the width of the adhesive strip is 0.4cm.
[0008] Preferably, the folded edge width is 0.5cm.
[0009] Preferably, a reinforcing strip is provided at the intersection of the side fold and the bottom fold to increase the sturdiness of the bottom triangular area of the placket.
[0010] Preferably, the placket fabric includes two sets of placket pieces, each placket piece including an outer piece, two sets of inner pieces and a lining piece connected in sequence, the outer piece, the first inner piece, the second inner piece and the lining piece are folded by three fold lines and then stacked in sequence.
[0011] Preferably, the two inner panels are cut with notches on the bottom side to reduce seam allowance when the two placket panels are sewn to the folded bottom edge.
[0012] Preferably, the folded edge is placed between the inner and lining pieces after being folded back, and the second stitch passes through the outer piece, the folded edge, the inner piece, and the lining piece in sequence.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] The placket structure of this utility model is suitable for pullover shirts. The reverse folding process improves the firmness of the sides and bottom triangular area of the placket, preventing the placket from splitting or deforming under stress. Attached Figure Description

[0021] Example 1: A preferred embodiment of this utility model provides a ripstop pullover shirt placket structure, including a front fabric 1 and a placket fabric 2 with an opening on one side. The front fabric 1 has a placket opening 3, which extends from the neckline to the middle of the garment. The placket opening 3 includes two side edges 31 and a bottom edge 32. A notch 33 is provided at the intersection of the side edges 31 and the bottom edge 32. The side edges 31 and the bottom edge 32 are folded inward along the notch 33 to form a folded edge 34. The fold of the folded edge 34 is heat-pressed to form a heat mark 35. The side edges 31 are sewn to the placket fabric 2 for the first time at a distance of 0.1 cm from the heat mark 35. The folded edge 34 is folded inward along the heat mark 35. The folded side edges 31 are then sewn to the placket fabric 2 for the second time.
[0022] The placket fabric 2 includes two sets of placket pieces. Each placket piece includes an outer piece 21, two sets of inner pieces 22 and lining pieces 23 connected in sequence. The outer piece 21, the first inner piece 22, the second inner piece 22 and the lining pieces 23 are stacked in sequence after being folded by three fold lines.
[0023] The outer piece 21 is sewn to the side edge 31 for the first time. The side edge 31 is folded inward along the heat mark 35 to form a folded edge 34 with a width of 0.5cm. After the folded edge 34 is folded back, it is placed between the inner piece 22 and the inner piece 23. The second sewing passes through the outer piece 21, the folded edge 34, the inner piece 22 and the inner piece 23 in sequence.
[0024] This placket structure is suitable for pullover shirts. The reverse folding process improves the strength of the sides and bottom triangular area of the placket, preventing splitting or deformation when the placket is under stress.
[0025] Example 2: A preferred embodiment of this utility model provides a ripstop pullover shirt placket structure, which differs from the above embodiment only in that: the two sets of inner pieces 22 are cut with notches 24 on the side facing the bottom edge 32, so as to reduce the seam thickness when the two sets of placket pieces are sewn to the folded bottom edge 32.
[0026] Example 3: A preferred embodiment of this utility model provides a ripstop pullover shirt placket structure, which differs from the above embodiments only in that:
[0027] The folded edge 34 is provided with an adhesive strip with heat-pressing points. The folded edge 34 is bonded to the front fabric 1 by heat pressing. The width of the adhesive strip is 0.4cm and the width of the folded edge 34 is 0.5cm.
[0028] Example 4: A preferred embodiment of this utility model provides a ripstop pullover shirt placket structure, which differs from the above embodiments only in that:
[0029] A reinforcing strip 4 is provided at the intersection of the folded edge 34 on the side 31 and the folded edge 34 on the bottom 32 to increase the sturdiness of the triangular area at the bottom of the placket.
[0030] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
