Concise Bible Dictionary:

Various Hebrew and Greek words are translated “linen,” and there can be no doubt that linen made of flax was known in ancient Egypt and to the Israelites; but cloths generally are called “linen” whether made of cotton or flax, some being distinguished as “fine linen,” such as was worn by the priests, kings. The word shesh, often translated “fine linen” and “fine twined linen” (for the curtains of the tabernacle, etc.) signifies “whiteness,” and is applicable to both fine linen and cotton (Ex. 26:1,311Moreover thou shalt make the tabernacle with ten curtains of fine twined linen, and blue, and purple, and scarlet: with cherubims of cunning work shalt thou make them. (Exodus 26:1)
31And thou shalt make a vail of blue, and purple, and scarlet, and fine twined linen of cunning work: with cherubims shall it be made: (Exodus 26:31)
). Joseph was arrayed in “vestures of fine linen” (Gen. 41:4242And Pharaoh took off his ring from his hand, and put it upon Joseph's hand, and arrayed him in vestures of fine linen, and put a gold chain about his neck; (Genesis 41:42)). The wrappings on the ancient Egyptian mummies were for a long time judged to be cotton, but by the use of the microscope they have been discovered to be linen.
