<p>PURPOSE:To maintain the safety of users so as to ensure them against burn by forming a self burning type ignition agent from a binder consisting of a water-soluble cellulose derivative. CONSTITUTION:An ignition line 6 is obtained by immersing a linear object such as carbon fiber in a water-soluble binder solution of ignition agent consisting of oxidizing and reducing agents and drying it. The ignition line 6 is so constructed as to ignite by a spark generating device 9 and hinder the exothermic reaction of an exothermic agent 4, unless it burns up to this agent. A water-soluble cellulose derivative is necessary as a binder for forming a self burning type ignition agent. By way of example, this cellulose derivative may be methyl cellulose and hydroxypropylmethyl cellulose. Under the moisture which can normally occur, the exothermic agent is normally ignited to generate heat and, in a case where an excessive amount of water intrudes into an exothermic body storing chamber 2, the exothermic reaction is hindered by decomposition of the composition of the ignition agent or loss of its shape.</p> |
