TOOTHBRUSH BRISTLE AND TOOTHBRUSH

摘要

PROBLEM TO BE SOLVED: To provide toothbrush bristles which can be highly densely implanted when they are used in a non-flat line toothbrush and which can provide the toothbrush with fine touch and excellent cleaning-properties and the toothbrush at least partly using the bristles. SOLUTION: The toothbrush bristles consist of cut bristles of synthetic resin monofilaments. A section perpendicular to the bristle longitudinal direction has a profiled section form other than a circle. The cut bristles are 10-25 mm in length, which are used in the non-flat line toothbrush.
