Fibrous materials of zinc oxide (ZnO) and zirconium oxide (ZrO2) were prepared by impregnating sewing threadswith Zn and Zr solutions, prepared from alkoxides of zinc and zirconium, respectively, and then heat-treating the threads in theatmosphere or in a nitrogen gas (500~1000°C). With the use of cotton fibers for the sewing threads, ZnO and ZrO2 fibers havingrelatively high strengths could be prepared. The crystallinities of the prepared ZnO and ZrO2 fibers were identified by thedetermination of their X-ray diffraction patterns. Generally, the fibers heat-treated in the atmosphere and in the surrounding nitrogengas had white and black colors, respectively. The fibers heat-treated in the surrounding nitrogen gas had higher strengths than thoseheat-treated in the atmosphere. ZnO or ZrO2 only was observed in the fibers heat-treated in the atmosphere, while it was observed inthe fibers heat-treated in the surrounding nitrogen gas that ZnO or ZrO2 was evenly dispersed in carbon fibers.
