Dhaka Muslin

Nearly 200 years ago, Dhaka muslin was the most valuable fabric on the planet. Then it was lost altogether. 

In late 18th-Century Europe, a new fashion led to an international scandal. In fact, an entire social class was accused of appearing in public naked.

The culprit was Dhaka muslin, a precious fabric imported from the city of the same name in what is now Bangladesh, then in Bengal. It was not like the muslin of today. Made via an elaborate, 16-step process with a rare cotton that only grew along the banks of the holy Meghnariver, the cloth was considered one of the great treasures of the age. It had a truly global patronage, stretching back thousands of years – deemed worthy of clothing statues of goddesses in ancient Greece, countless emperors from distant lands, and generations of local Mughal royalty.

There were many different types, but the finest were honoured with evocative names conjured up by imperial poets, such as "baft-hawa", literally "woven air". These high-end muslins were said to be as light and soft as the wind. According to one traveller, they were so fluid you could pull a bolt – a length of 300ft, or 91m – through the centre of a ring. Another wrote that you could fit a piece of 60ft, or 18m, into a pocket snuff box.

Dhaka muslin was also more than a little transparent.While traditionally, these premium fabrics were used to make saris and jamas – tunic-like garments worn by men – in the UK they transformed the style of the aristocracy, extinguishing the highly structured dresses of the Georgian era. Five-foot horizontal waistlines that could barely fit through doorways were out, and delicate, straight-up-and-down "chemise gowns" were in. Not only were these endowed with a racy gauzy quality, they were in the style of what was previously considered underwear.

In one popular satirical print by Isaac Cruikshank, a clique of women appear together in long, brightly coloured muslin dresses, through which you can clearly see their bottoms, nipples and pubic hair. Underneath reads the description, "Parisian Ladies in their Winter Dress for 1800".

Meanwhile in an equally misogynistic comedic excerpt from an English women's monthly magazine, a tailor helps a female client to achieve the latest fashion. "Madame, ’tis done in a moment," he assures her, then instructs her to remove her petticoat, then her pockets, then her corset and finally her sleeves… "‘Tis an easy matter, you see," he explains. "To be dressed in the fashion, you have only to undress."

Still, Dhaka muslin was a hit – with those who could afford it. It was the most expensive fabric of the era, with a retinue of dedicated fans that included the French queen Marie Antoinette, the French empress Joséphine Bonaparte and Jane Austen. But as quickly as this wonder-cloth struck Enlightenment Europe, it vanished.

By the early 20th Century, Dhaka muslin had disappeared from every corner of the globe, with the only surviving examples stashed safely in valuable private collections and museums. The convoluted technique for making it was forgotten, and the only type of cotton that could be used, Gossypiumarboreum var. neglecta – locally known as Phutikarpas – abruptly went extinct. How did this happen? And could it be reversed?

A fickle fibre 

Dhaka muslin began with plants grown along the banks of the Meghnariver, one of three which form the immense Ganges Delta – the largest in the world. sEvery spring, their maple-like leaves pushed up through the grey, silty soil, and made their journey towards straggly adulthood. Once fully grown, they produced a single daffodil-yellow flower twice a year, which gave way to a snowy floret of cotton fibres.

These were no ordinary fibres. Unlike the long, slender strands produced by its Central American cousin Gossypiumhirsutum, which makes up 90% of the world’s cotton today, Phutikarpas produced threads that are stumpy and easily frayed. This might sound like a flaw, but it depends what you’re planning to do with them.

Indeed, the short fibres of the vanished shrub were useless for making cheap cotton cloth using industrial machinery. They were fickle to work with, and they’d snap easily if you tried to twist them into yarn this way. Instead, the local people tamed the rogue threads with a series of ingenious techniques developed over millennia.

The full process involved 16 steps, each of which was so specialist, it was carried out by a different village around Dhaka, which was then part of Bengal – some in what is now Bangladesh, some in what is now the Indian state of West Bengal. It was a true community effort, involving the young and old, men and women.

First, the balls of cotton were cleaned with the tiny, spine-like teeth on the jawbone of the boal catfish, a cannibalistic native of lakes and rivers in the region. Next came the spinning. The short cotton fibres required high levels of humidity to stretch them, so this stage was performed on boats, by skilled groups of young women in the early morning and late afternoon – the most humid times of day. Older people generally couldn’t spin the yarn, because they simply couldn’t see the threads.
