FIBER HAVING ELECTRIC RESISTIVITY CHANGING WITH TEMPERATURE AND FIBER STRUCTURE AND FIBER PRODUCT

摘要

PPROBLEM TO BE SOLVED: To provide a fiber whose electric resistivity changes in response to temperature, to provide a fiber structure; and to provide a fiber product. PSOLUTION: This fiber is characterized by containing fine particles changing their electric resistivity in response to temperature, such as a perovskite oxide represented by a chemical formula, ASB1-x/SBBSBx/SBMnOSB3/SB, and containing Mn, in the fiber. Therein, A is at least one of rare earth element ions of La, Pr, Nd, and Sm, and B is at least one of alkaline earth metal ions of Ca, Sr, and Ba. PCOPYRIGHT: (C)2007,JPO&INPIT
