MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202641025170 A) filed by Subalakshmi R, Chennai, Tamil Nadu, on March 3, for 'biodegradable baby diaper using biomass-derived polylactic acid (pla) and banana fiber absorbent core.'
Inventor(s) include Subalakshmi R; and Dr. N. Jayachitra.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a fully biodegradable baby diaper constructed from a composite material comprising polylactic acid (PLA) derived from biomass sources and mechanically or chemically extracted banana fibers. The diaper includes a multilayer structure in which the top sheet is formed from hydrophilic-treated PLA nonwoven, the absorbent core comprises a PLA-banana fiber composite blended with biodegradable superabsorbent polymers, and the back sheet is composed of breathable yet liquid-impermeable PLA film. The incorporation of banana fiber provides enhanced absorbency, faster wicking, improved tensile strength, and reduced material cost while maintaining full compostability. The invention further discloses manufacturing methods including fiber surface modification, composite formation, thermo-bonding, hot-melt attachment, and ultrasonic sealing. The resulting baby diaper offers improved comfort, reduced skin irritation, and enhanced environmental sustainability compared to conventional petrochemical-based diapers."
