Reasons for shrinkage of cotton bed sheet
The bed sheet of pure cotton is composed of plant fiber. When the bed sheet is soaked in water, water molecules will enter into the cotton fiber to make the fiber expand. When the weft (or warp) expansion of the fabric becomes thick, the bed sheet will shrink. The longer the bed sheet is immersed in water, the larger the shrinkage will be, of course, the larger the shrinkage will be, and it will not shrink endlessly.
