Wash only the collarSourced
A separate shirt part reduced the washing task
Detachable collars could be removed and washed independently from a shirt. If only the collar was dirty, the whole garment did not need washing. Their manufacture became a significant industry in Troy, New York. A small removable component changed the laundry workload.
The part most in need of cleaning could come away on its own.
