Description

Sewing method of invisible zipper of double-layer garment

[ technical field ] A method for producing a semiconductor device

The invention relates to the technical field of garment manufacturing, in particular to a sewing method of an invisible zipper of double-layer garment.

[ background of the invention ]

The zipper is a common accessory of modern clothes and can play a role in opening and closing. In order to further avoid the zipper from affecting the appearance, many garments, particularly skirts, have zippers designed as invisible zippers. However, how to sew the invisible zipper with the fabric is a complicated process, which can not only make the zipper hidden, but also make the clothes fit and not easy to damage. In the prior art, when the invisible zipper is arranged on the double-layer clothes and the lower end of the zipper is layered, a knife edge is inevitably generated; the cut is easy to be cracked after being washed by water, and the manufacturing process of the transparent light and thin fabric such as European-root yarn, lace and the like needs to be improved.

[ summary of the invention ]

The invention aims to provide a sewing method of an invisible zipper of double-layer clothes, which can install the invisible zipper on the double-layer clothes, form layering at the lower end of the zipper and avoid generating a knife edge.

The technical scheme of the invention is as follows:

a sewing method of an invisible zipper of double-layer clothes is characterized by comprising the following steps:

step a, overlapping the surface layer and the front surface of the inner layer, and sewing along the remained seam head until the sealing position at the bottom end of the zipper is finished;

step b, the zipper is unzipped, the zipper is aligned with the surface layer and the inner layer from the open end of the zipper, the zipper is sewn with the surface layer and the inner layer along the inner sides of the zipper teeth, and the end of the sealing position at the bottom end of the zipper is reached;

c, overlapping the reverse sides of the two surface layers, and sealing the bottom end of the zipper by x₀Sewing according to a straight line track to form a width x₁Sewing the edges to the bottoms of the garment pieces, overlapping the front surfaces of the two surface layers, and sewing according to a straight line track from the zipper sealing position to form the width (x)₁+0.1cm) surface layer edge sewing, and finishing sewing to the bottom of the garment piece;

d, overlapping the reverse sides of the two inner layers from the bottom end of the zipper to the lower part (x)₀+0.1cm) to form a width x₁Sewing the edge till the bottom of the garment piece is finished;

e, clamping the sewed surface layer between two inner layers to form four layers of overlapped surface materials, sewing along a linear track from the zipper sealing position to form the product with the width of x₁The inner layer is sewn to the lower part (x) of the zipper sealing position₀+0.1cm)；

F, trimming and edge-covering the zipper, the surface layer and the inner layer;

and g, positioning the lower opening of the zipper to the inner layer.

Further, x is as defined above₁The width of the hem is 0.1 cm-0.5 cm, and the hems with different widths can be selected according to specific styles and materials.

Further, x is as defined above₀The sewing point is 2 cm-4 cm, and the sewing point is arranged at the position, so that the operation is convenient and the crack is not easy to fall off.

Further, x is as defined above₀3cm, the sewed invisible zipper is more beautiful and firm, the operation is convenient, and the sewed double-layer clothes are smoother.

Further, the zipper in the step f is trimmed until the tail part is 3-4 cm away from the sealing position, the zipper is kept at a proper distance, the zipper is durable, edge covering is facilitated, and the zipper is attractive and practical.

Furthermore, the tail of the zipper in the step f is cut into a semicircular shape, the transition is smooth, and the cloth and a human body are not easily scratched.

Furthermore, the step f is carried out by wrapping with oblique stripe cloth, so that the multiple layers of rough edges are hidden, and the product is attractive and practical.

The invention has the following beneficial technical effects: the invisible zipper can be arranged on the double-layer clothes, the upper surface layer and the inner layer of the invisible zipper at the sealing position cannot be separated, the lower surface layer and the inner layer form a separated cloth layer at the sealing position of the zipper, and no knife edge is generated in the whole process, so that sequelae of spalling after washing cannot be caused; the invention has wide application range and can be carried out on various fabrics, including European-root yarn, lace and other transparent light and thin fabrics.
