I'll second the Dickies recommendation. Any time I need something dressier than jeans but still able to be worked in, Dickies are the first choice.

Much of the Dickies line is poly/cotton. If they are one of the cotton versions, they may dry quicker than the Carhartts because the Carhartts are a heavier cloth. Every Carhartt pants I've looked at is 100% cotton.

I've had the exact opposite results with jeans. Poly/cotton jeans will last years past a similar pair made of cotton. The cotton pants begin to show their age in the wear areas & seams when the poly/cotton ones are still going strong. They also dry faster.
