Dental floss brushes, as described herein, are extremely difficult to coat with wax coatings. When conventional waxes are utilized, the floss brush becomes matted and gummy. We have developed an improved wax coating solution which results in a thin, uniform coating with good adhesion characteristics. This invention relates to an improved floss brash product and to a novel process for its manufacture. In particular this invention is directed to an improved floss brash made of a textured, high tenacity nylon yarn which provides the scraping functions of a floss under high tension and the brushing functions of a yarn under low tension. The present yarns require a wax coating to improve lubricity during use. The present product exhibits a uniform, thin wax coating. The present process imparts a thin coating by utilizing a "viscosity lowering agent" in the wax coating solution. |
