Abstract:
1. A method of obtaining a fiber texture of carbon from a cellulose precursor, the method including the steps of: spinning cellulose filaments from a viscose solution or a cellulose solution; subjecting the cellulose filaments to washing in water; subsequently impregnating the washed and non-dried cellulose filaments with an aqueous emulsion of at least one carbonization-enhancing organosilicon additive; drying the impregnated cellulose filaments to obtain dried cellulose filaments provided with said carbonization-enhancing organosilicon additive; making a fiber texture made up of said impregnated and dried cellulose filaments provided with said carbonization-enhancing organosilicon additive, the making of the fiber texture including a step of forming a yarn or unidirectional sheet from a plurality of said impregnated and dried cellulose filaments; and carbonizing the fiber texture.
