The Central Silk Technological Research Institute (CSTRI) in Bengaluru is set to revolutionize the silk industry with the introduction of a new purity-testing technology. Collaborating with Germany-based startup Senorics, CSTRI will employ near-infrared (NIR) spectroscopy to verify the authenticity of silk fabrics. This innovative approach aims to enhance quality assurance and consumer protection, addressing long-standing issues with traditional testing methods.
Enhancing Silk Quality Assurance
The new technology leverages NIR spectroscopy, a non-invasive method that analyzes material composition without damaging the fabric. This advancement will allow real-time verification of silk authenticity by identifying its molecular composition. Traditionally, silk purity has been tested through destructive means such as burn tests or chemical analysis, which are impractical for large-scale verification and unreliable in preserving the fabric’s integrity.
P. Sivakumar, the member secretary and CEO of the Central Silk Board (CSB), highlighted the significance of this development. He noted that the new technology would reassure customers about the quality of their purchases, especially those without the “Silk Mark India” label. This label is a certification provided by CSB to authenticate silk products, and its absence often raises doubts about the fabric’s authenticity.
S. Periyasamy, Director of CSTRI, explained how this technology could transform silk sales. The device can analyze the properties of materials like polyester, nylon, and cotton, allowing sellers to install these sensors in their stores. This will enable customers to verify the quality of products on the spot, offering greater transparency and trust in the silk market.
Addressing Consumer Concerns
One of the key issues this initiative seeks to address is the frequent mislabeling of silk products. Customers often face difficulties in confirming the authenticity of silk fabrics, particularly when purchasing products without the “Silk Mark India” label. The introduction of NIR spectroscopy promises to mitigate this problem by enabling quick, on-the-spot testing at retail outlets.
The ability to differentiate between silk and synthetic fibers like polyester or nylon will offer greater transparency to consumers. This technology will not only be useful for silk but also for other fibers often blended with or substituted for silk. The adoption of this cutting-edge technology comes as Karnataka, India’s largest silk producer, continues to innovate in the field.
With CSB celebrating its platinum jubilee this year, this project is a long-awaited move to replace outdated testing methods. The collaboration with Senorics researchers is expected to be formalized within the next six months, marking a significant milestone in the silk industry.
Future Implications for the Silk Industry
The implementation of NIR spectroscopy in silk testing is expected to have far-reaching implications for the industry. By ensuring the authenticity of silk products, this technology will enhance consumer confidence and potentially increase sales. The non-destructive nature of NIR spectroscopy means that the integrity of the fabric is preserved, making it a more practical and reliable method for large-scale verification.
This initiative is part of a broader effort by CSTRI to modernize the silk industry and improve quality assurance processes. The ability to quickly and accurately verify the authenticity of silk products will be a game-changer for both consumers and retailers. As the technology becomes more widely adopted, it is likely to set new standards for silk testing and quality assurance.
The collaboration between CSTRI and Senorics represents a significant step forward in the field of textile technology. By leveraging advanced scientific methods, the silk industry can address long-standing issues and pave the way for future innovations. This project underscores the importance of continuous improvement and adaptation in maintaining the high standards of the silk industry.
