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!

Self lubricating describes the creation of a film between two surfaces. That film could be oil based or metal based. Certain plastics for example often slowly leak oils allowing for this. With metals you’d usually need something soft against a harder metal. As the soft metal rubs against the hard metal it would make sort of a metal dust. That dust is slicker than the bare metal.
