Background

Splicing the cut pieces in the production process of the garment, splicing different cut pieces formed after cutting to form a complete garment, and forming a hem structure at the splicing position of two or more cut pieces; the conventional hemming structure generally adopts a overlock seam or a one-way overlock seam structure, the overlock seam structure is relatively simple to produce and is most widely applied, the overlock seam is exposed outside, and overlock threads are easily damaged and fall off in the garment ironing or washing and non-ironing processes, so that fabric yarns are broken and silked, and the wearing effect is influenced; in addition, the overlock seam needs to be overlocked in advance through an overlock machine, and the overlock machine may cut the fabric in the overlock process, so that the size of the cut piece is affected.

The other structure is a one-way edge-covering sewing structure, when two cut pieces are spliced, the width of one edge of the cut piece is trimmed, and the other edge of the cut piece is used for wrapping the trimmed edge of the cut piece.

The invention has the following patent: a seamless shirt with crease-resistant and non-ironing functions and a manufacturing method (authorized bulletin No. CN103220926B) thereof propose a novel seamless shirt manufacturing method, wherein the fabric of the seamless shirt does not contain adhesive fiber components, the manufacturing method mainly comprises a cutting process, a wireless sewing process and a ironing process, wherein: in the cutting procedure, when the fabric is cut into cut pieces, all or part of the fabric is cut integrally; in the wireless sewing procedure, all or part of the framework adhesive material is primarily adhered to the seam head of the corresponding cut piece along the edge by adopting a framework adhesive technology; manufacturing a hard collar and a button; when the framework bonding technology is adopted, the fabric is cut into required cut pieces; the width of the framework adhesive material coated on the cut pieces is set to be 0.2-4 cm; the initial bonding seam mode is U-shaped bonding, straight-line bonding or double-layer parallel bonding; the different parts of the shirt are bonded by half-overedged, opposite-bonded or external-bonded bonding, and the skeleton bonding material is primarily bonded to the corresponding cut piece seam along the edge; the obtained product is a seamless shirt with crease resistance and non-ironing function, and the whole seamless shirt is free of bonding fiber components, and comprises all seams, joints or overlocks of a collar, a front piece, a back piece, an armhole, a lower hem, cuffs, a top fly and a breast pocket, wherein all seams, joints or overlocks are not sewn by using sewing threads, and corresponding parts are combined into a whole by using a skeleton bonding technology; although the shirt can ensure the flatness of the shirt without sewing threads and wrinkling, the production cost is high, the requirements on the adhesive material and the adhesive process are very high, the adhesive material is influenced by the environment and the like, for example, the fabric shrinks under the condition of overhigh or overlow temperature or after multiple times of washing, the clothes have the risk of cracking, the use of the clothes is influenced inversely, the popularization is difficult, and the application range is narrow.

Therefore, there is a need for further improvements in the process of making a hem structure for non-ironing garments.
