Zippers are now widely used in clothes around the world and are an integral part of people's lives. According to the material of the zipper, the zipper is divided into three categories: Metal Zipper, resin zipper, Nylon Zipper. Compared with metal zipper and resin zipper, nylon zipper has the characteristics of low cost, large output and high penetration rate. So today we come to understand the installation method of nylon zipper.

1. First prepare the nylon zipper and the fabric to be zippered;

2. Use a 1.5cm wide seam allowance to sew the place where you need to install the zipper first, and then iron the seam allowance separately. If you don't need to zip the whole seam, then the stitch length of this seam section without zipper should be finer, and the start and end positions should be fixed with inverted stitches.

3. Align the nylon zipper with the front side facing down and the seam allowance. Use hand stitches to sew it tightly with the seam allowance.

4. Turn the fabric to the front, and attach the sewing machine with a single-sided presser foot for sewing zipper, push the presser foot down to the right of the needle, start from the right side of the opening of the nylon zipper, and press the fabric with 0.7 cm seam Daoming Line

5. When the stitching on one side is completed and you are ready to sew the other side, first look at the position of the iron on the bottom zipper. If you can avoid it, you can directly turn 90 degrees and let the needle cross the zipper to the other side to start Suture. When turning, keep the needle at the lowest position, then raise the presser foot, and then lower the presser foot to continue sewing after turning. When sewing over the zipper teeth, do not step on the electric motor, but turn the sewing machine wheel by hand to allow the needle to carefully pass over the nylon zipper teeth to avoid broken needles;

6. If the bag iron is just right for the turning position, then you can only push the presser foot down to the left of the needle, and start to sew a bright thread on the left from the opening. Be careful not to forget the needle at the beginning and end of the crimp. Finally, remove the sparse stitches from the fabric;
