I just purchased two packages of complete bedsheets and pillow cases, 100% cotton, 200 thread per inch.I always wash sheets before using. These sheets were laundered alone. While hanging them on clothes racks in my kitchen, I had tons of cotton dust from them. There was a film of dust across the kitchen floor, table, everywhere it was like a cloud in the air when you shook the sheets/pillowcases. I have never seen this before with cotton sheets. Anyone out there know what this is about?
