How do YKK zippers self lubricate and zip more smoothly with more use?

Question

I’ve been researching this all morning and keep running into articles that explain why YKK is a great company and what is unique about their zippers, but no article that explains the technical design of the product.

Would love an explanation that goes beyond the very simple “YKK zippers actually lubricate themselves as you zip and unzip them.”

Thank you!

After more than twenty years and I can finally understand this OutKast verse: “[Let me be bambino on your snipples YKK on yo’ zipper, lick you like a – lizard when I’m slizzard or sober; six million ways to fold ya](https://youtu.be/-JfEJq56IwI)”. Thanks OP!
