muslin

n. strong cotton cloth that is used for sheets and various other purposes

Muslin is a type of finely-woven cotton fabric, introduced to Europe from the Middle East in the 17th century. Its first recorded use in England was in 1670. It was named for the city where Europeans first encountered it, Mosul, in what is now Iraq, but the fabric actually originated from Dhaka in what is now Bangladesh. [1]
