Abstract Of The Disclosure Thermal insulating material of cellulosic fibers is prepared by treating wood chips or other fibrous cellulosic material with saturated steam at elevated temperatures and pressures and then fiberizing the treated material. A fire-retardant chemical is added to the material immediately prior to fiberization. The resulting fiberized cellulosic material when dried exhibits superior flame and fire resistance properties.
