Biodegradable and eco-friendly materials are preferred due to less environmental impacts in compare to synthetic and chemical compounds. Serishm is known as a natural protein based material which includes Collagen and has been considered as an ancient coating on textile materials. However, there is a lack of scientific approach and experimental finding to show the capability of using this material as the fire retardant for fabrics. Therefore, the main objective of this work is to investigate the possibility of using Serishm as a natural fire-retardant material. 23 various samples in fabric type (polyester, cotton and cotton/polyester) , Serishm content in 150 cc water (5, 10 and 15 g) were investigated under various conditions of padding pressure (2, 3 and 4 MPa), padding times (2, 3 and 4 times) andmethod of coating (pad dry cure, conventional method and injection molding of silicone-resin. Moreover, as cotton fabrics were highly flammable, various nano-silica contents (2, 4 and 8%) were used to determine the most appropriate condition for cotton fabrics. Flame retardancy and physical properties of each sample were evaluated. According to the test results, polyester fabric coated by Serishm showed better flame retardancy in compare to cotton and co tton/polyester fabrics. By increasing the padding times, the sample was capable to stop the firing procedure. The conventional coating showed better results in compare to padding methods, while the injection molding was the most appropriate method in compare to the other methods. It was concluded that the protein resin could completely penetrate into the fabric texture during injection molding. Therefore, by applying Serishm through injection method even cotton fabrics showed better flame retardancy.
