What rules must be followed when sewing zippers?
There are general rules that every seamstress must follow when sewing zippers into products. We recommend to get acquainted with them.
- When sewing a zipper, you need to use a leg and a needle in accordance with the recommendations of sewing equipment manufacturers.
- In the process of manufacturing the product, the zipper should be sewn as early as possible. This is due to the fact that it is easier to sew a zipper if both sides of the final product lie flat.
- Do not sew the raw edges of the material to the zipper, they can get between the coil in slider and cause the zipper break.
- The product must always be sewn to the tape using tension to prevent waviness and to ensure an correct position of the zipper.
- All rows of stitches must be flat and with gap from the spiral in such a way as to ensure smooth movement of the slider. For shoes, this gap should be not less than 4 mm.
- Never cut ends of zippers. In this case, the zipper may open up from the bottom. Cutted ends of the tape close to the top stops will cause the clothes to rub in these places. The ends of the tape at the top stops must be sewn into the product at an angle of 45° to the axis of the zipper.
- If zipper is high-quality sewned, then both halves should fit tightly to each other, it should close without tension, and the slider should move freely. To ensure the smooth movement of the slider, the zipper can be treated on both sides with paraffin or wax.
