Abstract
Mustard agent is a chemical compound containing chlorine and sulfur elements that was first used during World War I on July 12, 1917, by the German army in the city of Ypres. During the imposed war between Iran and Iraq, different chemical weapons were used many times by the Iraqi army. According to published statistics, mustard gas and nerve agent were the most used chemical agents in this era. Mustard gas damages the body through breathing and skin. This gas damages the body by reacting with the DNA of the cell and preventing its division, therefore, when faced with it, defensive operations should be performed. On the other hand, it is impossible to carry anti-chemical clothes permanently, so a quick and immediate solution should be sought for articles with mustard chemical agent in sudden exposure. In this research, a solution was made by using a combination of polyurea and amino silicone fluid, which after layering it on the military cloth, completely prevented the penetration of mustard gas both physically and by reacting with mustard gas to destroy it. This solution prevents it from passing by closing the openings between the thread and the fabric of the clothes. On the other hand, by making the surface of the fabric hydrophilic, it prevented the absorption of mustard gas on the surface of the fabric. At the same time, the amino silicone fluid enters into the alkylation reaction with the mustard agent as a sacrificial agent and destroys its structure.
