Are putting black work pants in the dryer to iron them a bad idea?

The dryer is my iron, as long as the clothing can be dried then it won't hurt a thing. Just put the pants in the dryer for 5 minutes(with a dryer sheet). Take them out while they are still hot, lay them on a flat surface and smooth out the wrinkle's with your hands.

I am not sure if I understand your question correctly.

Are you putting the iron also into the dryer? That might be a bad idea.

Are you trying to iron in the dryer instead of on a ironing board? Didn't think so.

Do you want to know if a dryer is a good replacement for an iron? Yes, and no.

In terms of dewrinkling or in terms of drying the pants?

Do you know about all this and do it with your blue pants on a regular basis and only want to know if black dye behaves more or less the same?

You can if ur dryer has a crease free setting... you wont get the same result as with an iron though because you iron the line in the front of business pants.

Only if you also put the iron in the dryer with the pants. Makes an awful racket.

It would be easier just to iron them yourself.
