What is Invisible Zipper?

Invisible Zips are made up of chain teeth, sliders, restriction codes (front and back codes) or locking pieces. The key part of the Zip is the teeth, which directly determine the strength of the zip's side pull. Generally, Invisible Zippers have two pieces of chain tape, each with a row of chain teeth, and the two rows of chain teeth are staggered with each other.

How to sew an Invisble Zipper?
1.First of all, prepare an Invisible Zip and before you put it on, unzip it and use an iron to iron it. Because all Nylon Zips Invisible are stretchy after use, we iron them to release their stretchiness and then sew them onto the garment without distortion.
2.Sew the rest of the garment together, leaving the part that holds the #3 Invisible Zipper. Have a needle insert or a large-headed needle ready.
3.Put the ironed Zip. Use a large head pin to fix it to the position to be fitted, taking care to balance both sides. Don't put one on top of the other. Once the Zipper is in place, look at the front and back to make sure it is in the right position.
4.To sew Invisible Zips, it is necessary to change the presser foot of the sewing machine. There is a special presser foot for Concealed Invisible Zips, which must be changed to fit Invisible Zippers, we remove the old presser foot and replace it with the presser foot for Invisible Zips.
5.At this point place the fabric on the sewing machine with the presser foot next to the edge of the Nylon Zip, remembering that it must be right next to each other so that the Zippper is not visible when sewn. If necessary, you can push the Nylon Invisible Zipper with your hand. After you have sewn one side together, sew the other side. Beginners may need to practice a few more times.
6.After sewing. Try the front and back of the Invisible Zip to see if it is smooth, and that the Zip is not visible from the front. This is the only way to pass. Practice makes perfect, if you do it a few times you will become familiar with the process and the results will get better and better.

The difference between Invisible and non-Invisible Zipper, which is better?

Custom Nylon Invisible Zipper is a fabric seam that can be pulled tight so that the presence of the Zip is not visually perceptible. A non-Invisible Zip can be seen as a Zipper. In terms of use, it depends on what you are using it for, if you are using it for a dress, an #3 Invisible Zip is perfect. For tops, bags... the non-invisible ones are fine. Overall, each has its own strengths and weaknesses. They all have a similar lifespan.
