<P>PROBLEM TO BE SOLVED: To produce a surface heating material constituted of a formed carbonized material having a light, flexible and porous fiber structure good in processability and reactivity and a strong texture exhibiting high carbon properties by a very simple means at a low cost. <P>SOLUTION: A raw material having a porous structure consisting of an entangled combined body of cellulose single filaments having twisted, wavy and crimped forms is directly subjected to carbonizing/baking treatment by heating without adding a binder in a nonoxidative atmosphere. The entangled binding between the single filaments is strengthened by the carbonization-shrinkage effect generated by the above treatment, and the texture is stabilized and strengthened. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
