Description

Technical Field

[0001] The utility model patent relates to the technical field of clothing sewing, in particular to a sewing structure. Background Art

[0002] The overlock structure can be used for the seaming of conventional clothing, but its disadvantage is that it is easy to form a protruding bone position at the seam edge, making the back of the clothing uneven and easy to rub against the body, causing a more obvious foreign body sensation. Existing boneless sutures are mostly achieved through a four-needle six-thread structure, which leaves complex stitches on the outer surface of the clothing, affecting the design of some clothing; to achieve the four-needle six-thread structure, the front and back of the two pieces to be seamed need to be attached together, so the two pieces need to be fixed on both sides of the sewing needle for feeding operations, which requires a large operating space and restricts production efficiency.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Combined with the embodiments and Figure 1-5 , a sewing structure, comprising a stitching thread group passing through a garment layer, the garment layer comprising a first garment 1 and a second garment 2 which are arranged opposite to each other on the front side, and the first garment seam edge 13 and the second garment seam edge 23 are overlapped on the same side to form a side surface of the garment layer, and the upper surface of the garment layer is the reverse side 12 of the first garment layer;

[0020] The sewing thread group includes a bottom thread 3 and a top thread 4 which are sewn to the garment layer;

[0021] The bottom line 3 is arranged on the upper surface of the garment piece layer, and the bottom line 3 is bent circuitously on the reverse side of the first garment piece 1 to form a first bending section 31 close to the seam edge 13 of the first garment piece and a second bending section 32 far from the seam edge 13 of the first garment piece, and the first bending section 31 and the second bending section 32 are arranged alternately;

[0022] The upper thread 4 includes a first coil and a second coil arranged in an interlaced manner, the first coil needle loop 411 is interwoven and fixed with the second bending section 32, and the first coil coil column 412 penetrates the first garment piece 1 and the second garment piece 2, so that the first coil extension line 413 is located on the reverse side 22 of the second garment piece; the first coil extension line 413 is connected to the second coil extension line 423, the second coil coil column 422 is laid flat on the reverse side 22 of the second garment piece, and the second coil coil column 422 is connected to the side of the garment layer, so that the second coil needle loop 421 is hooked through the side of the garment layer to the first bending section 31 located on the reverse side 12 of the first garment piece, and the second coil does not form a perforation on the garment layer. When sewing, the front side of the first garment piece is opposite to the front side of the second garment piece, and the superimposed garment layer is placed on the working platform to carry out the feeding and sewing operation.

[0023] Furthermore, the second bending section is located at the midpoint between two adjacent first bending sections.

[0024] The length directions of the first stitch loops 411 and the first garment part seam 13 are parallel to each other, and a plurality of first stitch loops 411 are equidistantly arranged on the first garment part reverse side 12 .

[0025] The first garment piece 1 and the second garment piece 2 are both selected from elastic fabrics.
