Type of material
Type of bed sheet material affect the comfort and care. Generally it’s made of cotton. Cotton bed sheet is very preferred because it is easy to absorb sweat and cool.
In addition to cotton bed sheet, there are other materials. Such as silk or cashmere. Both these materials are expensive. Treatment would not be arbitrary. If you have a bed sheet with this material should be washed with dry clean. Washing by dry clean will be safer to keep the shape and color of silk and cashmere.
