Title:
BRUSH BRISTLE
Document Type and Number:
Japanese Patent JP2012045276
Kind Code:
A
Abstract:

To provide brush bristles where different kinds of brush bristle materials mutually adhere each other by using an ultrasonic vibration.

The brush bristles are the bristles where grinding brush bristle materials and polishing brush bristle materials, where abrasive grains with different properties are mixed, adhere each other by forming a welding part by an ultrasonic vibration on mutual contact surfaces. at least one of first abrasive grains are mixed in the grinding brush bristle material, and at least one of second abrasive grains are mixed in the polishing brush bristle material. It is favorable that the brush bristle materials are made of a thermoplastic resin, etc., for example. The brush bristle materials where the two kinds of abrasive grains with different properties are mixed are obtained by generating frictional heat by the ultrasonic vibration on the mutual contact surfaces, so as to form the welding part. It is also favorable that pressurization force is added to the welding part by the ultrasonic vibration during generation of the frictional heat.
