MUMBAI, India, July 25 -- Intellectual Property India has published a patent application (202411001993 A) filed by Chairman, Defence Research & Development Organisation, New Delhi, on Jan. 10, 2024, for 'bicomponent complex conductive yarn and its fabric.'
Inventor(s) include Mohit Katiyar; Kamal Kumar; Amit Saraiya; Ashok Kumar Yadav; and Mayank Dwivedi.
The application for the patent was published on July 25, under issue no. 30/2025.
According to the abstract released by the Intellectual Property India: "Bicomponent conductive yarn is formed by two fibre forming polymers arranged as 'core' and 'shell', the core being made from polyamide fibers and the shell composed of fluoropolymer filled with conductive filler wherein the filler is added in amount of 65-75% by wt. Both the outside and inside surfaces of shell bear smooth coating of fluoropolymer composed of conductive filler particles. When manufacturing yarn, first the conductive composition is prepared composed of fluoropolymer in organic solvent. The conductive particles are dispersed using rotary pulsating mixer which is followed by evacuation and secondly coating of the polyamide yarn with aforesaid developed conductive polymer composition and passing it through a customized die to maintain uniform coating thickness. Finally, the solvent is removed in drying section at 120 2oC which lead to the formation of integrated "core-shell" yarn."
