Muslin, a Phuti carpus cotton fabric of plain weave, was historically hand woven in the areas of Dhaka and Sonargaon in Bangladesh and exported for many centuries. The region forms the eastern part of the historic region of Bengal. The muslin trade at one time made the Ganges delta and what is now Bangladesh into one of the most prosperous parts of the world. Of all the unique elements that must come together to manufacture muslin, none is as unique as the cotton, the famous "phuti karpas", scientifically known as Gossypium arboreum var. neglecta. Dhaka muslin was immensely popular and sold across the globe for millennia. Muslin from "India" is mentioned in the book Periplus of the Erythraean Sea, authored by an anonymous Egyptian merchant around 2,000 years ago, it was appreciated by the Ancient Greeks and Romans, and the fabled fabric was the pinnacle of European fashion in the 18th and 19th century. Production ceased sometime in the late 19th century, as the Bengali muslin industry could no longer compete against cheaper British-made textiles.

Muslin is a cotton fabric of plain weave. It is made in a wide range of weights from delicate sheers to coarse sheeting. It gets its name from the city of Mosul, Iraq, where it was first manufactured.
