<P>PROBLEM TO BE SOLVED: To improve the abrasion resistance of a fiber guide for guiding a fiber containing hard particles to elongate the life. <P>SOLUTION: The fiber guide has a yarn-contacting part composed of a sintered body which comprises alumina of 65-96 mass% and zirconia of 4-35 mass%, and in which the average particle diameters of the alumina and the zirconia are ≤1.2 μm. The abrasion resistance of the yarn-contacting part can be improved by preventing the dropout of the sintered body by suppressing the progress of crack even if the crack is generated at the grain boundary of the sintered body. <P>COPYRIGHT: (C)2011,JPO&INPIT |
