Eli5 Why does it matter what temperature the water is when we do laundry?

I’ve been a “throw everything in and wash on cold” person forever, but I started to notice certain things such as towels that typically require hot or warm water didn’t feel right anymore. Once I switched back they came out feeling soft and fluffy as usual. Why does it matter?

At the very least, materials become more pliable when warm. Try shoveling warm mud vs cold mud for example. It’s easier to remove something from clothing that’s warm.

Also, chemical reactions tend to be sped up when the temperature is higher. Since there are at least some reactions happening between the detergent and the dirt, it would help that way as well.
