Surat, Gujarat | August 1, 2025 — In a major leap toward responsible textile innovation, Grasim Industries’ Cellulosic Fashion Yarn business has officially launched Raysileco, a next-generation sustainable and traceable viscose filament yarn (VFY) under the trusted Raysil brand. The unveiling took place at the 7th edition of Yarn Expo Surat, organized by the Southern Gujarat Chamber of Commerce and Industry (SGCCI).
Raysileco is crafted from wood pulp sourced exclusively from certified, sustainably managed forests, delivering full supply chain transparency from origin to end-product. It integrates advanced physical and digital traceability technologies, making it a standout solution in the global push for sustainable fashion.
Speaking at the launch, Mr. Satyaki Ghosh, CEO of the Cellulosic Fashion Yarn business at Grasim Industries, shared:
“Raysileco embodies the spirit of innovation with robust sustainability credentials and advanced traceability technologies. This launch reflects our drive to evolve with dynamic market needs and deliver value where performance, responsibility, and trust converge.”
He further emphasized that the product reinforces Grasim’s commitment to end-to-end traceability, giving value chain partners the confidence to verify the source and quality of every filament they use.
A Technological Leap in Traceability
Raysileco is distinguished by its dual-layered traceability system:
-
Physical molecular markers embedded directly into the yarn, and
-
Blockchain-powered digital traceability through TextileGenesis™, utilizing Fibercoins™ — unique digital tokens that track the yarn’s lifecycle from source to retail.
This tamper-proof, real-time digital record not only ensures accountability and authenticity but also helps brands meet increasingly strict global sustainability regulations.
Mr. Ghosh added:
“The traceability mechanism employs both physical markers and digital technologies. Our partnership with TextileGenesis™ enables secure, blockchain-based tracking from source to store.”
A Milestone in Sustainable Manufacturing
Manufactured at Grasim’s modern production facilities in Kalyan (Maharashtra) and Veraval (Gujarat), Raysileco is a testament to the company’s commitment to scalable, smart, and tech-enabled manufacturing.
Raysileco is fully biodegradable, responsibly produced, and designed to safely return to nature at the end of its lifecycle, aligning with circular economy goals.
Unique Industry Position
Grasim’s Raysil brand remains the only global provider of all three viscose filament yarn technologies:
-
Pot Spun Yarn (PSY)
-
Continuous Spun Yarn (CSY)
-
Spool Spun Yarn (SSY)
With Raysileco, the company is setting a new global benchmark in traceability, transparency, and sustainable yarn innovation, empowering fashion brands to make responsible sourcing decisions.
