1. Industrial Ecosystem of Sankarankovil & Kovilpatti Dyeing & Texturizing Corridors
The Sankarankovil & Kovilpatti corridor specializes in high-value upstream textile processing that bridges raw fiber spinning with high-speed circular knitting:
- High-Temperature Package Dyeing Vats: Operating computer-controlled stainless steel package dyeing vessels at elevated temperatures (130°C to 135°C) under 0.4 MPa pressure, local dye houses process high-tenacity nylon 6,6, recycled polyester, and bio-based polyamides with deep dyestuff penetration and uniform shade consistency (Delta E < 0.3).
- Air-Jet & Friction Draw-Texturizing (DTY): Specialized texturizing units convert flat filament yarns into lofty, air-entangled microfibers with high crimp contraction (28% to 35%). This imparts superior stretch recovery, soft tactile hand-feel, and enhanced capillary moisture transport to elastomeric activewear fabrics.
- Zero Liquid Discharge (ZLD) Infrastructure: In compliance with strict environmental mandates, major units in Sankarankovil operate 100% ZLD plants utilizing multi-stage reverse osmosis (RO), mechanical vapor recompression (MVR), and solar evaporation pans. Over 98% of process water is recycled back into dye baths, guaranteeing zero hazardous effluent discharge.
