Description

Technical Field

[0001] This utility model relates to the field of seamless edge technology for clothing, specifically a two-way seamless edge structure for wrinkle-free clothing. Background Technology

[0002] In the garment manufacturing industry, wrinkle-free clothing is favored by consumers for its convenience and good wearing shape. The craftsmanship of its two-way seamless edge structure directly affects the quality of the garment. However, most wrinkle-free garments still have obvious defects in their two-way seamless edge structure.

[0003] Traditional binding techniques often use single-sided or one-time binding to treat the seams of fabric pieces, covering only one edge. This results in the top and bottom edges of the seam not being finished simultaneously, leading to inconsistent binding quality and severely impacting the overall aesthetics of the garment. This fails to meet consumers' demands for a high-quality appearance. Furthermore, in single-sided binding, the seam only acts on one edge of the fabric piece (e.g., binding only the top or bottom), causing the stress at the seam to be concentrated on one side. For example, when the garment is stretched, the seam on one side must bear all the external force, while the other edge of the fabric piece lacks support, making it prone to loosening and breakage, thus reducing the quality of the seamless binding. To address the shortcomings of existing technologies, we propose a two-way seamless edge structure for wrinkle-free garments to solve the above problems. Utility Model Content

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a two-way seamless edge structure for wrinkle-free clothing, including a first cut piece and a second cut piece, wherein a first splicing part and a second splicing part are respectively provided on the sides of the first cut piece and the second cut piece that are close to each other, and an upper overlock piece and a lower overlock piece are respectively provided on the top and bottom of the first cut piece and the second cut piece.

[0005] The first splicing part is folded upward and installed inside the upper binding piece, and the second splicing part is folded downward and installed inside the lower binding piece. The widths of the first and second splicing parts folded upward are the same, and the widths of the upper and lower binding pieces are the same.

[0006] Preferably, the upper overlock sheet has an upper overlock portion one and an upper overlock portion two on both sides, and the lower overlock sheet has a lower overlock portion one and a lower overlock portion two on both sides.

[0007] Preferably, the upper seam portion one and the lower seam portion one have the same width, the upper seam portion two and the lower seam portion two have the same width, and the width of the upper seam portion one and the lower seam portion one is smaller than the width of the upper seam portion two and the lower seam portion two.

[0008] Preferably, the upper overlock portion one and the upper overlock portion two are fixedly installed on the top of the first cut piece and the second cut piece respectively by the second adhesive portion.

[0009] Preferably, the lower bound seam part one and the lower bound seam part two are respectively fixedly installed on the bottom of the second cut piece and the first cut piece by the fourth adhesive part.

[0010] Preferably, the first splicing part is folded upward and fixed between the upper seam-covering part and the upper seam-covering piece by the first adhesive part, and the second splicing part is folded downward and fixed between the lower seam-covering part and the lower seam-covering piece by the third adhesive part.

[0011] Preferably, the upper overlock portion two and the upper overlock sheet are fixedly filled with an upper filler sheet through a first adhesive portion, and the lower overlock portion two and the lower overlock sheet are fixedly filled with a lower filler sheet through a third adhesive portion.

[0012] Preferably, the distance from the top of the upper overlock sheet to the two sets of cut pieces is equal to the distance from the lower overlock sheet to the two sets of cut pieces.

[0013] This utility model discloses a two-way seamless edge structure for wrinkle-free garments, which has the following beneficial effects: The two-way seamless edge structure of this wrinkle-free garment features overlock panels at the top and bottom of two sets of cut pieces. The first and second splicing parts are connected by folding them in opposite directions and installing them with the upper and lower overlock panels. This allows for simultaneous edge binding of the top and bottom of the first and second splicing parts, thereby improving the aesthetics of the edge binding of the two sets of cut pieces. The use of upper and lower overlock panel structures, with the upper overlock panel connecting one pair of first splicing parts and the lower overlock panel connecting one pair of second splicing parts, ensures that while binding the two sets of cut pieces, it also increases the connection strength between the two sets of cut pieces and the two sets of overlock panels, preventing seam separation under tension and improving the quality and aesthetics of the edge binding between the two sets of cut pieces and the two sets of overlock panels.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] This utility model discloses a two-way seamless edge structure for wrinkle-free clothing.

[0023] According to the appendix Figure 1-4 As shown, the device includes a first piece 1 and a second piece 2. The sides of the first piece 1 and the second piece 2 that are close to each other are respectively provided with a first splicing part 11 and a second splicing part 21. The top and bottom of the first piece 1 and the second piece 2 are respectively provided with an upper overlock piece 3 and a lower overlock piece 4. When binding the splicing parts of the two sets of pieces, the two sets of splicing parts and the two sets of overlock pieces are installed and connected respectively. The first splicing part 11 and the second splicing part 21 and the upper overlock piece 3 and the lower overlock piece 4 are fixed by multiple sets of adhesive parts, so as to achieve the purpose of binding the first splicing part 11 and the second splicing part 21 of the two sets of pieces.

[0024] The first splicing part 11 is folded upwards and installed inside the upper binding piece 3, and the second splicing part 21 is folded downwards and installed inside the lower binding piece 4. The widths of the first splicing part 11 and the second splicing part 21 folded upwards are the same, and the widths of the upper binding piece 3 and the lower binding piece 4 are the same. By folding the first splicing part 11 and the second splicing part 21 upwards and installing them in the upper and lower binding pieces, the top and bottom of the first splicing part 11 and the second splicing part 21 can be bound simultaneously, thereby improving the aesthetics of the binding of the two sets of cut pieces. By using the upper and lower binding piece structure, and binding the first splicing part 11 through the upper binding part 31 and binding the second splicing part 21 through the lower binding part 41, the connection strength between the two sets of cut pieces and the two sets of binding pieces can be improved while binding the two sets of cut pieces, avoiding the situation of separation under pulling, and improving the binding quality of the two sets of cut pieces and the two sets of binding pieces.

[0025] The upper overlock piece 3 has an upper overlock section 31 and an upper overlock section 35 on each side, and the lower overlock piece 4 has a lower overlock section 41 and a lower overlock section 45 on each side. The upper overlock section 31 and the lower overlock section 41 have the same width, and the upper overlock section 35 and the lower overlock section 45 have the same width. The width of the upper overlock section 31 and the lower overlock section 41 is smaller than the width of the upper overlock section 35 and the lower overlock section 45. The space formed inside the two sets of overlock pieces after overlocking is filled by two sets of filling pieces, so as to ensure that the end face of the overlock piece after overlocking is in a horizontal state, thereby improving the aesthetics of overlocking the splicing part of the two sets of cut pieces.

[0026] Upper overlock part 1 31 and upper overlock part 2 35 are respectively fixedly installed on the top of the first piece 1 and the second piece 2 through the second adhesive part 34. Lower overlock part 1 41 and lower overlock part 2 45 are respectively fixedly installed on the bottom of the second piece 2 and the first piece 1 through the fourth adhesive part 44. Multiple sets of adhesive parts are evenly double-sided adhesive, with adhesive dots distributed on both sides. After high-temperature ironing, the connected pieces, overlock parts, and filling pieces can be fully bonded, improving the firmness after installation.

[0027] The first splicing part 11 is folded upward and fixed between the upper overlocking part 31 and the upper overlocking piece 3 by the first adhesive part 33. The second splicing part 21 is folded downward and fixed between the lower overlocking part 41 and the lower overlocking piece 4 by the third adhesive part 43. After the second splicing part 21 is fixedly connected to the lower overlocking part 41 and the lower overlocking piece 4 by the third adhesive part 43, the connected third adhesive part 43 is ironed at high temperature by an ironing machine, so that the second splicing part 21 is fully bonded to the lower overlocking part 41 and the lower overlocking piece 4 by the third adhesive part 43.

[0028] The upper overlock section 35 and the upper overlock piece 3 are fixedly filled with an upper filling piece 32 through a first adhesive part 33. The lower overlock section 45 and the lower overlock piece 4 are fixedly filled with a lower filling piece 42 through a third adhesive part 43. The distance from the top of the upper overlock piece 3 to the two sets of cut pieces is equal to the distance from the lower overlock piece 4 to the two sets of cut pieces. The upper overlock piece 3 and the lower overlock piece 4 are located at the top and bottom of the two sets of splicing parts, respectively, and have the same height, which can further improve the quality and aesthetics of the two sets of cut pieces after overlocking.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
