Malda silk

What is Malda silk?

Malda silk is a yarn rather than a finished cloth. It comes out of Malda district in West Bengal, where two silkworms supply it: the Nista strain of Bombyx mori and a bivoltine worm of Japanese origin. Thread reeled from Nista cocoons ranks among the finest silk anywhere, and cloth made from it is soft instead of stiff. The fibre carries a strong golden yellow cast, and it is thin, measured at roughly 2 to 2.4 denier, the unit used for thread gauge. Most of it leaves the district as yarn for other weaving towns.

Where does Malda silk come from?

Silk work around Malda is old. Kautilya's Arthashastra, which the sources date to 321 BC, mentions Kausheya fabrics obtained from a land called Pundariksha, given as the ancient name for this part of Bengal. Later the region's output travelled as Bengal silk, or Ganga silk, shipped out through Malda to Europe and elsewhere. A local story collected by Hunter tells of a cloth trade with Russia in the sixteenth century, with large amounts of Malda silk going to Mirzapur and Benares through monk traders. Whether that account is record or folklore, it marks the town as a long-standing trading point.

How is Malda silk made?

Two kinds of cocoon feed the trade. One is the Nista variety of Bombyx mori, a local strain; the other is a bivoltine worm of Japanese origin, so called because it yields two broods in a year. The cocoon filament is reeled into yarn, and the resulting thread is unusually thin at 2 to 2.4 denier, which is what gives the cloth its soft handle. Every community development block of Malda district takes part in production. Murshidabad and Birbhum add to the supply, but around seventy per cent of the raw Nistari silk is reeled in Malda.

Colours, motifs and borders

The sources are clear on colour and little else: the Nista silk is bright golden yellow. Its thread is extremely fine, and that fineness passes into the cloth, described as soft. As a yarn it has no pattern of its own. Whatever decoration appears belongs to the saris it goes into. Baluchari, garad and korial are the three sari types named as taking Malda Nistari yarn, and the design work sits with the weaving centres that buy the thread rather than with the reelers.

How Malda silk is worn

On its own Malda silk is never worn. It reaches the body as thread inside a sari, most often a Baluchari, garad or korial. How those saris are tied and pleated is not set out in the sources, so the description stops at the cloth. Abroad the yarn has a second life: Bhutan buys it to weave two traditional garments, the gho and the kira, so thread from a Bengal district becomes part of another country's dress.

When Malda silk is worn

The sources do not link Malda silk to weddings, festivals or rites. Its story is a working one, of yarn moving out of Bengal's reeling households to weaving towns and to buyers elsewhere. Demand is described as strong in northern India, with Uttar Pradesh picked out, and in the south of the country. Some yarn is sold within India and some is shipped overseas, Bhutan among the destinations. Ceremonial use, where it exists, belongs to the saris rather than to the yarn.

Styles of Malda silk

Two silk strains feed this trade. Nista is the local one, valued for the fineness of its thread; the Japanese bivoltine worm is the other. The yarn is traded under the Nistari name, while Malda silk is the broader term for the district's output. Bengal's older export silks moved as Bengal silk or Ganga silk; today the same fibre travels as a named product with official protection. Production is not concentrated in one village, since every block of the district reels some.

What Malda silk means

In 2026 the Nista yarn from Malda received Geographical Indication protection, an official tie between a product and its home ground. For the district it is formal paperwork laid over an old reputation. Malda has served as a silk centre and market for a very long time, and the trade has shaped how the place is known. The Kausheya reference in the Arthashastra and Hunter's account of Russian buyers both feed local memory of that past. Behind the registration sit the reelers and growers spread across the district's blocks.
