Egg shell are considered as waste and are generally dumped in the landfills. As the world is moving towards the sustainable way to recycle the waste and hence adding value to the waste produced. The egg shell is consisting of essential amino acids and properties which are still unexploited in various textile processing. The egg shell has proteineous matter which makes it a natural flame retardant. Cotton is the majorly used fibre in the overall textile industry. In the present study the egg shell waste was used to prepare an extract which is further applied on cotton fabric as a flame retardant. The characterization of the above egg shell powder shows it has amine group present at 1072.6 as well as at 873.56cm - C-Cl halo compound is present confirmed through FT-IR analysis. Two peaks were observed in DSC curves at 224.4 0 C and 254.5 °C. A LoI of cotton has increased to 36 at a lower concentration of 30% while that compared with the conventional cotton fabric.
