Description

Manufacturing process of seamless bonding clothing pocket with laser perforation

Technical Field

The invention relates to a manufacturing process of a seamless bonding clothing pocket with a laser opening, and belongs to the field of clothing.

Background

In the clothing field, especially in colder occasions such as skiing grounds or in cold weather, the requirements on wind resistance, snow resistance, rain resistance and heat preservation of clothing are high, and for example, a pocket of the clothing is usually required to be provided with a zipper at an opening position of the pocket, so that articles can be prevented from slipping from the pocket on one hand, and the pocket can be closed on the other hand, and wind resistance, snow resistance, rain resistance and heat preservation are achieved. However, the pocket opening of the traditional clothing is generally rectangular, when the pocket is manufactured, an adhesive interlining is adhered to the back surface of the pocket position, then the fabric is opened through cutting equipment, and then a zipper is sewn at reserved seams in the opening by buckling, so that the precision is poor, the processing efficiency is lower, burrs are easily generated at the peripheral edge of a cutting hole, in addition, the zipper is generally sewn at the pocket opening through a suture, burrs are easily generated at the triangular parts cut at the two ends of the opening during sewing, in addition, pinholes are generated during sewing, the windproof and warm-keeping performance is reduced, particularly in fast outdoor skiing, wind, snow and rain are easy to invade through the pinholes, and the zipper is not effectively protected on the seams formed at the slider positions on the zipper due to the self structural characteristics. If the pocket is an elliptical opening, the round parts at the two ends are required to be buckled with the light seam, so that the round parts at the two ends are difficult to be round and smooth to wear.

In view of this, the present inventors have conducted intensive studies on the above problems, and have produced the present invention.
