Abstract
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.
Highlights
Nowadays, the main environmental concerns are due to the production and utilization of chemical compounds more than ever before [1,2,3,4,5]
Most of previous research studies have focused on hazards of using flame retardants but less .works have been done in the case of introducing green flame retardants the main objective of the present work is to investigate the capability of using a green material as a suitable fire retardant for fabrics
There is a lack of scientific experimental results to show the capability of using this material as the natural fire retardant for fabrics
Summary
The main environmental concerns are due to the production and utilization of chemical compounds more than ever before [1,2,3,4,5]. Some other researchers have focused on using biodegradable and eco-friendly compounds to be used as the flame retardant materials. Serishm is an ancient animal based material which was mostly used as a binder of fabric/wood in paintings for many years ago [14], and laterally was replaced by the conventional white wood glue. It is mainly made from a protein based material including Collagen. In the present work with the aim of introducing a biodegradable and eco-friendly material such as Serishm, the possibility of using this material in flame retardant applications such as textile fabrics was investigated
