FUZZ DROPOUT PROPERTY EVALUATION DEVICE OF FIBER SUBSTRATE END SURFACE, AND FUZZ DROPOUT PROPERTY EVALUATION METHOD OF FIBER SUBSTRATE END SURFACE

摘要

PROBLEM TO BE SOLVED: To provide a device and method of evaluating a fuzz dropout property from a fiber substrate, especially from an end surface from which fuzz is apt to drop.;SOLUTION: The fuzz dropout evaluation device of a fiber substrate end surface includes: a turn table that rotates; a disk sheet having a non-smooth surface fixed onto the turn table; and a substrate sheet support tool that charges a load to at least one true-circle-shaped fiber substrate sheet as a test piece, brings its end surface into contact with the non-smooth surface by charging a load, and supports the fiber substrate sheet in the center of the true circle so that the sheet rolls due to a friction force with the non-smooth surface.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
