How to choose a zipper
Important tips when purchasing zippers Because zippers have different adaptability in different environments, you should make special recommendations to the manufacturer when purchasing zippers:
1. What kind of products are the zippers applied to (such as luggage, shoes, ski jackets, raincoats, tents, jeans that need to be washed or leather products with high acidity) or other special requirements.
2. Requirements for restricted chemical substances in zipper, such as whether the belt cloth needs to be free of azo (AZO), whether the nickel release is qualified, or it can pass the needle detector.
Three 3#, 4#, 5# These refer to the number of the zipper, which is measured by the width of the zipper after it is closed. Simply put: the higher the number, the thicker the zipper. Usually, the zippers on our jackets are 5#, such as 8# and 10#, which are special zippers. They are very rough and need to be customized. Usually, they are rarely used. 4YG refers specifically to the zipper on the trousers, which refers to the zipper of the 4# YG head. This zipper head has a lock, especially on jeans and casual pants. It is relatively firm and generally made of metal teeth. The vast majority of brand clothes will have custom zipper cards on the zippers of their clothes, usually in different shapes, and the brand's LOGO is engraved on it. It is a very detailed thing.
