Paper Abstract

On the basis of the principle of laser radiation and materials interaction, a laser-optical treatment method for toothbrush bristles (nylon et al., synthetic and polymeric materials) is provided. In this process, laser irradiation is stopped during melting and followed by cooling, so the free end of each bristle of toothbrush is formed for a smooth globe. The toothbrush with laser-optical end-globed bristles have many remarkable functions.
