Description

Technical Field

[0001] The present invention relates to the technical field of clothing, and particularly relates to a manufacturing process for clothing decorative pieces. Background Art

[0002] With the development of the economy, people have higher and higher requirements for the aesthetics of clothing, and clothing with decorations is gradually popular among people. Usually, patterns are printed on clothing or some decorative fabrics of specific shapes are cut and sewn on the clothing. Existing decorative fabrics are usually flat-shaped, and when making decorative fabrics, it is impossible to lock the edges of the decorative fabrics well. The cut-out decorative fabrics are directly sewn on the clothing, resulting in the exposed cutting edges of the decorative fabrics, which easily causes the thread ends at the edges of the decorative fabrics to come loose and affects the quality. Summary of the Invention

[0003] The object of the present invention is to overcome the above-mentioned existing problems, and provide a manufacturing process for clothing decorative pieces. This manufacturing process can avoid the exposure of the cutting edges, improve the quality of the decorative pieces, and has folds in the shape, bringing a three-dimensional visual effect and improving the decorativeness.

[0004] The object of the present invention is achieved by the following technical solutions:

[0005] A manufacturing process for clothing decorative pieces includes the following steps:

[0006] (1) Cutting: Cut out three heart-shaped cut pieces from the fabric. The three heart-shaped cut pieces are the first heart-shaped cut piece, the second heart-shaped cut piece, and the third heart-shaped cut piece respectively;

[0007] (2) Sewing the center: Overlap the first heart-shaped cut piece and the second heart-shaped cut piece. When overlapping, the first heart-shaped cut piece and the second heart-shaped cut piece are mutually misaligned. Sew the center between the first heart-shaped cut piece and the second heart-shaped cut piece to fix the first heart-shaped cut piece and the second heart-shaped cut piece to each other;

[0008] (3) Pleating and sewing: Rotate the second heart-shaped cut piece around the center, align the edges of the first heart-shaped cut piece and the second heart-shaped cut piece, and sew the first heart-shaped cut piece and the second heart-shaped cut piece along the edges to form a heart-shaped transition product. During the sewing process, pleat the excess fabric in the second heart-shaped cut piece, and then align it with the edge of the first heart-shaped cut piece to pinch out folds on the second heart-shaped cut piece; The second heart-shaped cut piece constitutes the pleated surface of the heart-shaped transition product;

[0052] (3) Pleating and sewing: Rotate the second heart-shaped cut piece 2 around the center, align the edges of the first heart-shaped cut piece 1 and the second heart-shaped cut piece 2 with each other, and sew and stitch the edges of the first heart-shaped cut piece 1 and the second heart-shaped cut piece 2 to form a heart-shaped transition product 12. During the sewing process, pleat the excess fabric in the second heart-shaped cut piece 2, and then align it with the edge of the first heart-shaped cut piece 1, so as to pinch out pleats 4 in the second heart-shaped cut piece 2; The second heart-shaped cut piece 2 constitutes the pleated surface of the heart-shaped transition product 12, and the first heart-shaped cut piece 1 remains flat;

[0053] (4) Sewing the third heart-shaped cut piece 3: Orient the pleated surface of the heart-shaped transition product 12 towards the third heart-shaped cut piece 3, align and overlap it with the third heart-shaped cut piece 3, sew and stitch the edges of the heart-shaped transition product 12 and the third heart-shaped cut piece 3, and leave an unsewn opening 5; At this time, the second heart-shaped cut piece 2 is located between the first heart-shaped cut piece 1 and the third heart-shaped cut piece 3, that is, the pleated surface is hidden inside and cannot be seen from the outside;

[0054] (5) Turning out the wrinkled surface: Through the reserved opening 5, turn out the wrinkled surface located inside to the outside to form a semi-finished heart shape. After turning out, the first heart-shaped piece 1 is located between the second heart-shaped piece 2 and the third heart-shaped piece 3, that is, the wrinkled surface and the third heart-shaped piece 3 are exposed outside, and the third heart-shaped piece 3 remains flat.

[0055] (6) Sewing decorative stitches: Sew the edges of the semi-finished heart shape to form a decorative piece.

(2.3) Place multiple second heart-shaped pieces on the intermediate plate in sequence and position them through the second positioning marks. (2.4) Flip the cover plate and cover the cover plate on the second heart-shaped piece. (2.5) Sew the center between the first heart-shaped piece and the second heart-shaped piece through a sewing machine. (2.6) Open the cover plate and take out the second heart-shaped cut piece. At the same time, the first heart-shaped cut piece will pass through the elongated slot and the round hole and be taken out together with the second heart-shaped cut piece. Before step (2), five first positioning notches are cut on the edge of the first heart-shaped cut piece, and five groups of second positioning notches are cut on the edge of the second heart-shaped cut piece, with two second positioning notches in each group.

2. The manufacturing process of a clothing decoration according to claim 1, characterized in that, The area of the second heart-shaped cut piece is larger than that of the first heart-shaped cut piece.

3. The manufacturing process of a clothing decoration according to claim 1, characterized in that In step (2), the line connecting the tip of the first heart-shaped cut piece and the center of the circle is the first straight line, the line connecting the tip of the second heart-shaped cut piece and the center of the circle is the second straight line, and the angle formed by the first straight line and the second straight line is an obtuse angle.

4. The manufacturing process of a clothing decorative piece according to claim 1, characterized in that, Step (4) is assisted and completed by the second template assisting mechanism; the second template assisting mechanism includes a base plate and a top plate; both the base plate and the top plate are made of transparent materials; the base plate and the top plate can be flipped along one side; multiple positioning marks for positioning the heart-shaped transition product and the third heart-shaped cut piece are provided on both the base plate and the top plate; an avoidance groove for avoiding the needle during thread stitching is provided in the positioning mark; the head and the end of the avoidance groove are not connected.

5. The manufacturing process of a clothing decoration piece according to claim 4, characterized in that, The specific steps for step (4) to be assisted and completed by the second template assisting mechanism are as follows: (4.1) Flip open the base plate, place the third heart-shaped cut piece on the base plate and position it through the positioning mark. (4.2) Place the wrinkled surface of the heart-shaped transition product facing down, overlap the heart-shaped transition product and the third heart-shaped cut piece, and position them through the positioning mark. (4.3) Flip the top plate and cover the top plate on the heart-shaped transition product. (4.4) Use a sewing machine to stitch the edges of the heart-shaped transition product and the third heart-shaped cut piece. (4.5) Open the top plate and take out the heart-shaped transition product and the third heart-shaped cut piece together.

6. The manufacturing process of a clothing decoration according to claim 1, characterized in that In step (3), with the second heart-shaped cut piece facing up, pinch out five wrinkles on the second heart-shaped cut piece in a clockwise direction.
