Does dryers actually damage clothes? - Lemmy

I see all sorts of answers online, but am not fully convinced. I tried finding some research on the longevity of clothes between wash and wash + dry. Considering that it dries for hours just the mechanical movement should damage the clothes I would assume?

What do you suppose you’re removing from the lint trap?
I know this question is intended as a joke but it has me thinking. What is lint, actually? If its from our clothing then why is it always the same colour? Like, why can I put in a load of white clothing but the lint is still black? Is the lint burnt? Or is lint a byproduct of laundry soap? Or is it both from our clothing and our laundry soap? I genuinely don’t know. I’ve never thought about it before
Wat. Mine is always the average colour of the load.
