My bachelor brother asked me this question and I disdn't have an answer, even though I have experienced this occasionally. He just bought a house and is buying linens etc. He purchased some bath towels that aren't very absorbent. I also have bought towels in the past that weren't as absorbent as others. They feel great to the touch, are 100% cotton and have been washed, but seem to do a crappy job of drying you off. Not cheap either. Are some cotton towels treated somehow? Is there something you can add to the wash to fix this? I figured there is a textile expert in this group, or at least someone who has also experienced this.
