Coatings were made from bee wax mixed with oil which were coconut oil, sunflower oil and barn oil, in different ratio. There were 1:1, 1:2 and 2:1 of bee wax mixed with oil. All floss was coated by
various mixtures at temperature 70, 80, and 90 degree Celsius, respectively. In this research “Nang Noi” silk race was selected to produce dental floss. This was because of results from experiments in the past research. Floss that made from four silk races were compared their mechanical properties, adsorption, and the smoothness. The results shown “Nang Noi” was the best silk race for producing dental floss.
