Description

Manufacturing process of non-ironing clothing bidirectional seamless edge structure

Technical Field

The invention relates to the field of manufacturing of clothing parts, in particular to a manufacturing process of a bi-directional seamless edge structure of non-ironing clothing.

Background

The clothing must splice the cut-parts in the production process, different cut-parts formed after cutting are spliced to form a complete clothing, and a hemming structure is formed at the splice position of two or more cut-parts; the conventional hemming structure generally adopts a hemming seam or a unidirectional hemming seam structure, the hemming seam structure is simpler to produce and is most widely applied, but the hemming seam is exposed outside, and in the ironing or water washing, non-ironing treatment and other processes of clothing, the hemming line is easily damaged and falls off, so that the yarn of the fabric is broken and drawn, and the wearing effect is affected; in addition, the overlock seam needs to be overlooked by a overlock machine, and in the overlock process, the overlock machine can possibly cut the fabric to influence the size of the cut-off pieces.

The structure is also a one-way edge-covering seam structure, when two cut pieces are spliced, the width of the edge-covering seam is trimmed, the trimmed edge-covering seam is wrapped by the edge-covering seam, the mode is convenient for sewing the straight line or the clothes with smaller radian, but the clothes with larger radian, such as women's clothes or children's clothes, are sewn, and the folded edge-covering position is easy to generate wrinkles due to larger difference of the inner arc length and the outer arc length between the two cut pieces, so that the appearance of the clothes is uneven, and the attractive appearance is influenced.

Chinese invention patent: the seamless shirt with crease-resistant and non-ironing functions and a manufacturing method thereof (authorized bulletin number: CN 103220926B) provide a novel seamless shirt manufacturing method, wherein the fabric of the seamless shirt does not contain adhesive fiber components, and the manufacturing method mainly comprises a cutting process, a wireless sewing process and an ironing process, wherein: in the cutting procedure, when the fabric is cut into cut pieces, all or part of the cut pieces are cut in a conjunct way; in the wireless sewing procedure, all or part of the framework binding material is bound to the corresponding cutting piece seam head along the edge by adopting the framework binding technology; manufacturing a collar and a button; when the skeleton bonding technology is adopted, firstly cutting the fabric 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 primary bonding joint mode adopts U-shaped bonding, linear bonding or double-layer parallel bonding; the different parts of the shirt adopt a half-wrapping-sewing, opposite-sticking or external-sticking bonding mode to primarily stick the skeleton bonding material to the seam head of the corresponding cutting piece along the edge; the obtained product is a seamless shirt with crease-resistant and non-ironing functions, the whole seamless shirt is free of adhesive fiber components, and comprises all seams, joints or wrapping seams of a collar, a front piece, a back piece, armholes, a lower hem, cuffs, a top fly and a chest bag, all of which are not sewn by adopting a sewing thread, and the corresponding parts are combined into a whole by adopting a skeleton bonding technology; the shirt can ensure the flatness of the shirt without wrinkling without adopting sewing threads, but has high production cost, very high requirements on adhesive materials and adhesive technology, and the adhesive materials are affected by environment and the like, for example, under the condition of overhigh or overlow temperature or after washing for many times, the fabric is shrunk, the garment has the risk of cracking, the use of the garment is adversely affected, the popularization is difficult, and the application range is narrow.

Therefore, there is a need for further improvements in the process of making hemming structures for non-iron garments.
