Tussar Silk

Tussar silk (also tussah, tasar, kosa) is a wild silk produced by Antheraea moth species — primarily Antheraea mylitta (Indian tropical tasar) and Antheraea paphia — that feed on forest trees like Terminalia arjuna (arjun) and Shorea robusta (sal) across central and eastern India. India controls over 70% of global tussar production.

Market data:

• Global tussar silk market: $350.71 million (2023) → projected $501.44 million (2032) at 4.1% CAGR
• India's tasar silk production: 1,363 metric tons (2024–25), up from 90 MT in 2001 — a 1,415% surge
• Part of broader Indian silk exports worth Rs 2,027.56 crore (2023–24)
• Indian silk market projected CAGR 8.5% over next 5 years

Historical origins:

• Indus Valley Civilization (2450–2000 BCE): Archaeological evidence of wild silk usage predating Chinese sericulture
• Mughal era (1526–1700s): Emperor Akbar brought Gujarati artisans to royal workshops (1572 AD)
• Bhagalpur became major trade hub connecting Middle East–Far East, exporting tussar to Europe via Champanagar harbor
• Central Tasar Research & Training Institute established in Ranchi (1964) — post-independence revival

Fiber properties:

• Natural color: Golden/honey/deep gold tone (no dyeing required)
• Texture: Coarse, textured, slightly grainy feel with characteristic slub surface
• Luster: Lower gloss than mulberry silk; distinctive microstructure
• GSM range: 30–500 GSM (light/sheer 40–50, medium 100–200, heavy 300–500)
• Tensile strength: High (comparable to other silks despite coarser texture)
• Biodegradable: 100% natural protein fiber

Production process:

• Wild silkworms feed on host trees in natural forest environment — no irrigation, fertilizers, or pesticides needed
• Cocoons cooked in hot water to soften sericin (gum-like protein binding filaments)
• Shorter fiber lengths than mulberry silk — wet-reeling produces better strength
• Fewer chemical treatments than conventional silk (often no degumming/bleaching)

GI-certified varieties:

• Gopalpur Tussar (Odisha): GI tag received 2009
• Jharkhand Tussar: GI-certified with global recognition
• Bhagalpuri Silk: GI tag for Bihar's "Silk City"

Ahimsa (non-violent) tussar:

Allows moth to complete life cycle and emerge naturally before cocoon harvest. Costs 2x regular tussar due to extra 10-day wait time and 1/6th fiber yield. Appeals to ethical/vegan consumers in the growing slow fashion movement.

Major production states (ranked):

1. Jharkhand (40%+ of total output): 80% of tasar sericulture activity; Central Tasar Research & Training Institute, Ranchi (since 1964); production surged from 90 MT (2001) to 1,363 MT (2024–25)
2. Chhattisgarh: 350+ tussar centers; key towns — Bastar, Jagdalpur, Raigarh, Bilaspur, Champa (Janjgir-Champa); Devangan weaving community
3. West Bengal: Malda district (major center); Bankura, Purulia tribal cultivation areas
4. Bihar: Bhagalpur = "Silk City" — 30,000 handloom weavers, 25,000 active looms, Rs 100 crore ($12M) annual trade, 50% exports
5. Odisha: Gopalpur region GI-tagged (2009); forest-based tribal production

Tribal artisan communities:

• Santhal: Major practitioners in Jharkhand/West Bengal
• Munda: Jharkhand-based traditional rearers
• Devangan: Chhattisgarh weavers
• Women-led tribal economy with generational inherited knowledge

Quality checks:

• Natural color should be warm gold/honey, not bleached or chemically treated
• Texture should have natural slubs (sign of authenticity — not a flaw)
• Burn test: Real silk burns like hair with soft gray ash; synthetics melt into hard beads
• Handloom shows slight irregularities; powerloom creates uniform perfection
• Verify GI tags (Jharkhand, Gopalpur) and Central Silk Board certifications
