Background

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides a bending deformation sequin which can meet the requirements of embroidering and then heating, and a production process adopting the bending deformation sequin. The purpose is as follows: the bending deformation sequin embroidery process can reduce the production cost, improve the working efficiency and improve the product quality.

The invention is realized by the following steps: a bending deformation sequin embroidery process comprises the following steps:

(1) stamping the sequin blank belt by using a die to form a sequin disc belt with a reserved inner hole, wherein the sequin is in a planar shape; the sequin blank is a heat-shrinkable polyester film, also called PETG composite film;

(2) embroidering one sequin at the top end of the sequin dribbling belt on the ornament at a preset position of the ornament by adopting an embroidery machine according to a preset pattern;

(3) cutting off the subsequent coils of the sequin coils, and returning to the step (2) until the embroidering is finished;

(4) the embroidery sequin decoration is deformed and bent at one time by a thermal deformation method, and the temperature range is controlled to be 60-90 ℃.

In the step (1), the PETG composite membrane has a layered structure: the PET base film 1, the coating layer 2, the mould pressing layer 3, the aluminum plating layer 4, the composite layer 5 and the composite shrink film 6 are sequentially overlapped;

in the step (1), the sequin tapes are circular sequin tapes, square sequin tapes, rhombic sequin tapes, star-shaped sequin tapes, flower-shaped sequin tapes and the like.

In the step (2), the embroidering is to embroider the planar sequin strip on the ornament by passing the thread through the reserved inner hole of the sequin strip according to the program setting of the embroidering machine.

The invention has the advantages that: compared with the prior art, the bending deformation sequin embroidery process has special advantages. Firstly, the process adopts a normal-temperature die to punch and shear the sequin strip, the normal-temperature die is generally low in price, and compared with the prior process that a special high-temperature die is needed to punch the sequin strip, the production cost is reduced, and meanwhile, the safety of operators can be guaranteed; secondly, when the sequins are sewn on the ornament, the sequins are in a uniform and neat plane sequin dribbling mode, and the sequins have good processing performance in a flat state, so that the phenomenon of missing stitch and jumping cannot occur; compared with the prior art, the process reduces the miss probability of the embroidery machine, reduces the rework rate and improves the product quality; finally, the final step of the process adopts a sequin one-time heating deformation technology to enable the sequins to bend and deform, the temperature is easy to control, and the uniform bending deformation sequins can be finally formed, so that the brilliant three-dimensional visual effect is presented. The process not only simplifies the prior procedures, reduces the production cost, but also improves the production efficiency.
