What kind of sewing method should different zippers follow?

Zipper is an item that is often used in daily handicraft production, whether it is making clothes or making bags. When the zipper is normally used, it is necessary to pay attention to whether there are any problems such as tooth loss and skew on the zipper. If these problems are found, they should be repaired in time, and do not pull hard. If the zipper is loose and the teeth are loose, you can use a small hammer to tap the zipper head a few times to make the upper and lower chain teeth bite tighter, so that the teeth will not come off again.


Before installing the nylon zipper, iron some adhesive lining on the zipper area, especially if sewing light weight or unstable fabrics, use a thinner adhesive lining about 1 inch wide and the length of the zipper opening lining, it will greatly help the effect and appearance of the sewed zipper.


There are three main sewing methods of nylon zipper, one is "overlapping", the 5/8 inch seam position of the garment car, and the zipper opening is sewn with dummy thread together with the seam position, and then the seam is ironed to open the closed seam. With the front of the zipper facing the wrong side of the seam, align the edge of the fabric on the right side of the zipper with the seam edge of the garment.


Secure the zipper fabric to the seam with 1/4" seams, being careful not to snag the garment, then turn the zipper over to the front and tuck the zipper along the fake seam or as close to the fake seam as possible. On the other side, open the fabric again so that the piece is facing up, stitch a 3/8" wide topstitch from the bottom front of the zipper to the top, then remove the basting.


The other is the "invisible form", which is an easy and quick way to install nylon zippers, because there is no need for false stitching and front stitching, using the invisible zipper foot, it can stitch the thread as close as possible zipper teeth, so as to achieve the invisible effect of the zipper "disappearing" in the garment panel when viewed from the front.


There is also a "middle seam" method of sewing zippers. After sewing the sewing position of the clothes, iron the seam, first sew the selvedge of the zipper on the seam of the garment, and then stitch the topstitching on the front of the clothes, and car to the appropriate position. To be flat, do not make the edge arched, use the unilateral presser foot from the bottom to the top, use the zipper foot, you can make the sewing line closer to the zipper teeth, the line spacing is 3/8 inch, you can use it before the top line Paint the 3/8-inch stitching position on the front of the garment piece, and then remove the fake stitching at the zipper opening after the car is finished, so that the zipper can be opened.


If the garments with zipper are "washed", it must be stated on the order that the garments require water washing. And please note that the fabric needs to be shrunk before sewing, so as to avoid the shrinkage of the fabric after washing, which will cause the zipper to arch and affect the hand feeling. When washing, the position of the slider must be fixed, otherwise the slider will slide down arbitrarily, and the slider is securely locked on the left and right teeth. According to the strength of the "wash", it can be twisted arbitrarily, and the twisting force exceeds the bearing capacity of a single tooth. , the teeth will fall off and the zipper will be damaged. The normal zipper will have a "not slippery" feeling after washing, and it can be painted with paraffin and pulled up and down two or three times. Guaranteed smoothness after washing.
