Why do bed sheets become more crinkly the longer it’s been since they’ve been washed?

Something that’s been bothering me for a long time. Even when I straighten them out again, they get more crinkles more quickly. In contrast, my newly cleaned sheets tend to preserve their integrity for at least a week on average.

This is an interesting question that you didn’t actually ask.

The answer is ‘entropy’. Things go from ordered to disordered naturally.

This isn’t 100% the truth, but it’s good enough for our purposes here.

The bullet point is that we (humans) create order, but nature abhors order – it prefers to mix things. Over time, things will mix. We can’t overcome that force because it’s ‘fundamental’.

It’s humidity, secretions, absorption, adsorption, pressure and heat.

Basically the fibres of your sheets come into contact with materials that results in them becoming stiffer, and in effect setting.
