Embodiment 1

[0027] A kind of processing method of toothbrush bristle provided by the invention comprises:

[0028] The toothbrush is heat treated so that the free ends of the toothbrush bristles have an irregular compound surface.

[0029] Wherein making the free end of the toothbrush bristle have an irregular compound curved surface refers to making the sharp edges and corners of the free end smooth, forming such as figure 2 For the irregular compound curved surface shown, the corners include not only the rough corners on the end face but also the corners between the end face and the end face perpendicular to the bristles of the toothbrush.

[0030] Wherein the material of the toothbrush bristles is any suitable material, including but not limited to resin, synthetic resin, animal hair, nylon and the like. Nylon is used in this embodiment. The bristles can be heat-treated, either by heat-treating the whole bundle of bristles, or only by partially heat-treating the free ends of the bri...

Embodiment 2

[0035] Compared with embodiment one, the difference of the processing method of a kind of toothbrush bristle provided by the present embodiment is:

[0036] The bristles of the toothbrush treated in this example were not fixed on the toothbrush. Full hair heat treatment (heat treatment of the entire bundle of toothbrush bristles). The material of the toothbrush bristles is polyolefin. The diameter of the toothbrush bristles is 0.1 mm to 1 mm, preferably 1 mm. The heat treatment method adopts laser. The heat treatment temperature is above 600 degrees Celsius, more preferably 600 degrees Celsius in this embodiment. The heat treatment time is 0.1-2s, more preferably 2s in this embodiment. The protective gas for heat treatment is nitrogen or inert gas. The orientation of the toothbrush bristles is vertically downward.

Embodiment 3

[0038] Compared with embodiment one, the difference of the processing method of a kind of toothbrush bristle provided by the present embodiment is:

[0039]The bristles of the toothbrush processed in this embodiment have been fixed on the toothbrush. Adopt all heat treatment on the toothbrush. The material of the toothbrush bristles is polyester. The diameter of the toothbrush bristles is 0.1 mm to 1 mm, preferably 0.5 mm. The heat treatment method is infrared heating. The heat treatment temperature is above 600 degrees Celsius, preferably above 650 degrees Celsius, more preferably 800 degrees Celsius in this embodiment. The heat treatment time is 0.1-2s, preferably 0.1-1s, more preferably 1s in this embodiment. The protective gas for heat treatment is nitrogen or inert gas. The orientation of the toothbrush bristles is vertically upward.

Abstract

The invention discloses a toothbrush bristle and a processing method thereof, wherein the processing method of the toothbrush bristle includes: heat-treating the toothbrush so that the free end of the toothbrush bristle has an irregular compound curved surface. The invention heat-treats the sharp edges and corners of the free ends of the bristles of the toothbrush to achieve a smooth effect, thereby avoiding damage to gums and enamel. At the same time, only the free ends of the toothbrush bristles are subjected to heat treatment, which can avoid heat treatment from causing damage to the rest of the toothbrush bristles and the rest of the toothbrush, and affect the overall quality of the toothbrush. Controlling the heating process allows the free ends of the bristles to be rounded, so that all sharp corners (including edge corners) are rounded, resulting in free ends with irregular compound surfaces.

Description

technical field [0001] The invention relates to the field of oral cavity cleaning, in particular to a toothbrush bristle and a processing method thereof. Background technique [0002] Toothbrush has been widely and long-term used as personal daily necessities for cleaning teeth and oral cavity. A good toothbrush can scrub the attachments on the teeth without damaging the gums or enamel, which puts high demands on the toothbrush. Wherein, the structure of toothbrush bristle has great influence on the quality of toothbrush, for example the shape of toothbrush bristle end, the hardness and flexibility of toothbrush bristle, the material of toothbrush bristle, the preparation process of toothbrush bristle all affect the quality of toothbrush. Among them, the bristle end of the toothbrush that directly contacts the toothbrush is the most direct factor affecting the quality of the toothbrush. [0003] Currently, untreated toothbrush bristles often have sharp edges at the ends tha...
