Annoying Laces

Image generated by AI using Bing Image Creator
Laces that keep opening do my head in. Even with double or triple knots, they seem to find a way to come undone. The reason is probably because they're made of polypropylene or nylon, two materials with a low coefficient of static friction, meaning the material is slippery. So as an experiment, I might try using one of these types of products which are used in industry to stop belt slip on machinery. The stuff, available in an aerosol can like WD40, is effectively the opposite of oil and improves friction.

In machines where the components aren't subjected to high loads which would cause a lot of wear, nylon is often used instead of more costly steel or brass. So for instance gears and pulleys are made of nylon, the advantage being its low coefficient of friction and no requirement to use grease or oil for lubrication. Most analogue wall clocks have nylon gears in the mechanism.
