Inventor(s) include Poornima University; and Dr. Ranu Burad.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "The current invention proposes an innovative and environmentally friendly textile fabric dyeing and treatment method which uses natural pigments sourced in plants and binded to the fabrics using bio-based binding agents to provide a long and sustainable color on both natural and artificial fabrics. The new technology aims at the large scale reduction of water usage as opposed to traditional processes of dyeing in addition to the absence of toxic chemicals, heavy metal mordants and other substances that cause environmental pollution. It involves the use of a special pre-treatment and fixation step that improves the fixation of pigments on fibers, giving it high color permanency, laundry, and anti-fading properties. The technique achieves rich, steady, and pleasing coloration using natural dyes and biodegradable binders without affecting the environmental sustainability. Moreover, the system can support different types of textile such as cotton, silk, wool, polyester and blended fabrics such that it can be used in industries. In general, this eco-dyeing and treatment method is an environmentally and health-friendly method to deal with synthetic dyes, as well as the means of producing textiles in a socially friendly manner, therefore, allowing the principles of green chemistry and saving resources, which provides high-quality and durable colored fabrics."
