燃施工方法の開発が急務となっている。2. Description of the Related Art A method for treating a flame-retardant glass fiber woven fabric has been developed. For example, according to Japanese Patent Application Laid-Open No. 50-138883, heat treatment of diorganopolysiloxane for a short period of time results in transparency and heat resistance. A product having excellent properties and flame retardancy can be obtained. When a flame retardant test is conducted by impregnating glass fiber with the treatment agent thus obtained, self-extinguishing property is obtained, but smokelessness is hardly achieved. On the other hand, in the event of fire in building materials, smoke often causes fatalities, and it is an urgent task to develop materials that emit less smoke and to develop flame-retardant construction methods with aesthetic colors by improving living culture. There is.
