Therefore, when purchasing zippers, they should give special suggestions to manufacturers: 1. What kind of products can zippers be applied to (such as leather suitcase, footwear, ski clothes, raincoat, tent, jeans or acid larger leather products) or other special requirements.

Two, the requirements for zipper ingredients, whether it does not contain AZO (AZO), nickel free, or can pass the needle detector.

Three, 3#, 4# and 5# refer to the number of zippers, which are measured by the width of the zipper.

In simple terms, the larger the number, the thicker the zipper.

Usually, the zippers on our jacket are all 5#, such as 8# and 10#. They are special zippers. They are very rough. They are very custom-made, usually less.

4YG specifically refers to the zipper on trousers, which refers to the zipper of the YG head of 4#. This zipper head is locked, especially jeans and casual pants, which are relatively strong and are usually metal teeth.

This is a zipper failure.

Serious.

The left and right teeth are pulled close so that the chain head can easily be closed by closing the zipper.

< p > 3. when the zipper is opened and closed, sometimes the chain head holds the line or cloth and makes the pull head not pull. In this case, if it is necessary to pull the pull head, it will bite deeper and deeper.

Pull the head back and spread the cloth aside.

Do not pull the pull head when you are biting completely, please slowly pull back.

And when sewing is pulled, please do not leave hidden trouble.

< p > 4. the clothes are worn for a long time and the drill is not easy to use because the loose heads of the zippers are loose. At this time, you can use a pair of pliers (no pliers or teeth to bite) to squeeze a pull head, so that the pull head is tightened and the zipper will be used well; < /p >
