Abstract

Carbon or graphite materials possessing textile characteristics are prepared by subjecting to carbonization and/or graphitization temperatures a permanently dehydrated heat-treated material which retains the characteristic physical attributes of the cellulosic starting material, and which is prepared by subjecting natural or regenerated cellulosic textile material in an oxidizing atmosphere to a temperature of 100-350 DEG C. for a time sufficient to cause the starting material to realize a weight loss based on the starting material of 20 to 50% and to have a volatile content of from 45 to 70%. The textile starting material, e.g. cotton, linen, jute or rayon, may be impregnated with an up to 50% by volume acid solution and then dried in air at room temperature prior to being heated. The acid constituent of the solution may be phosphoric, sulphuric, hydrochloric or nitric acid, diammonium phosphate or diethylchloro phosphate and the solvent may be water, alcohol or ketone. The cellulosic material may be in the form of fibres, filaments, yarns and battings or cloth and impregnated with a solution of acid initial decomposition of the cellulose molecule involving rupture of the C-O and C-H bonds with the evolution of H2O and ends at a point just prior to the scission of the main cellulosic molecule, the rupture of C-C bonds, and the evolution of hydrogen.ALSO:A permanently dehydrated heat-treated material retaining the characteristic physical attributes of the cellulosic starting material is prepared by subjecting natural or regenerated cellulosic textile material in an oxidizing atmosphere to a temperature of 100-350 DEG C. for a time sufficient to cause the starting material to realize a weight loss based on the starting material of 20 to 50% and to have a volatile content of 45 to 70%. The material produced may subsequently be subjected to carbonization and/or graphitization temperature (see Division C1). The textile starting material, e.g. cotton, linen, jute or rayon may be impregnated with an up to 50% by volume acid solution and then dried in air at room temperature prior to heating. The acid constituent of the solution may be phosphoric, sulphuric, hydrochloric or nitric acid, diammonium phosphate or diethylchloro phosphate and the solvent may be water, alcohol or ketone. The cellulosic material may be in the form of fibres, filaments, yarns and battings or cloth and impregnated with a solution of acid concentration 3 or 7% by volume respectively. The heat treatment commences with the concentration 3 or 7% by volume respectively.
