The invention discloses a method for manufacturing a double-zipper structure of a
mountaineering jacket, which comprises the following steps of: 1, sewing and connecting a third zipper with an edge seam of a front piece on one side of the
mountaineering jacket, taking a front middle piece after sewing, pressing an
adhesive tape on one side edge of the front middle piece along the length direction, and then sewing and connecting the front middle piece with a code belt of the third zipper, the sewing position and the code belt are
cut into lines of 0.15 cm through thin lines, then
hot melt adhesive is pasted for pressing, and after pressing, the sewing position and the code belt are flat and free of printing; secondly, a first zipper code belt is connected with a side seam of a front piece on the other side of the outdoor jacket in a sewing mode, the sewing position and the code belt are
cut into 0.15 cm lines through thin lines, then
hot melt adhesive is pasted for pressing, and the zipper is flat and free of printing after pressing; thirdly, a second zipper code belt is connected with the side edge, close to the first zipper, of the front middle piece in a sewing mode, the sewing position and the zipper code belt are
cut into 0.15 cm lines through thin lines, then
hot melt adhesive is pasted for pressing, and after pressing, the zipper code belt is flat and free of printing marks. Quality risks are effectively avoided, the cost is reduced, the production efficiency is improved, meanwhile, the overall quality is improved, and the service life of the outdoor jacket is prolonged.
