Abstract: A bamboo toothbrush manufacturing method may include an operation of preparing raw materials, which selecting some of the raw materials as materials suitable for manufacturing bamboo toothbrushes on the basis of a vascular bundle ratio on the cross-section of each of the raw materials; a milling operation of processing the selected materials into the shapes of toothbrush bodies; a pretreatment operation of placing the materials, which have been subjected to the milling process, in an environment having a certain temperature range and a certain humidity range for a certain time range; a hot pressing operation of inserting the materials into a press die, and heating and pressing the materials; an operation of sanding and coating the materials; a drilling operation of forming a plurality of holes in a head portion of each of the materials; and an operation of planting toothbrush bristles into the plurality of holes.

Abstract: Disclosed is a method of manufacturing bamboo toothbrush and a toothbrush manufactured thereby. According to the method of manufacturing bamboo toothbrush of a detailed embodiment of the present invention and a toothbrush manufactured by the method, it is possible to improve strength, surface roughness, and moisture resistance of a bamboo and adjust the color of the bamboo using hot pressing. Further, since sanding and polishing and separate coating and drying are not performed, the process time is reduced, whereby the manufacturing cost can be reduced.
