Benefits of technology

[0010]The present subject matter provides a round toothbrush bristle and a processing method thereof, in which at least one end of the toothbrush bristle is softly rounded to protect gum damage due to irritation of the one end of the toothbrush bristle and to provide a gum massaging effect for healthy gums with the rounded end of the toothbrush bristle.
[0011]Accordingly, one aspect the present subject matter provides a method of processing toothbrush bristles made of synthetic bristles for obtaining round-shaped toothbrush bristles comprising: cutting one end of a filament bundle of synthetic bristles; mechanically polishing the cut end of the filament bundle of synthetic bristles; heat treating the polished end of the filament bundle of synthetic bristles; and caustisizing the heat-treated end of the filament bundle of synthetic bristles into a round shape. Another aspect of the present subject matter is to provide tooth brush bristles made of synthetic bristles and having at least one end thereof round shaped by caustisizing. These toothbrush bristles, having at least one end softly rounded, can protect gum damage due to irritation by the one end of the toothbrush bristle and to provide a gum massaging effect for improving gum health.

Problems solved by technology

However, since part (B) is made of the same synthetic bristle and remains rough without additional processing after cutting, part (B) is in a damaged state due to cutting.
When such a fine bristle toothbrush is used for a predetermined period of time, while part (A) can remove foreign substance, part (B) continues to irritate the gum, causing gum damage.

Embodiment Construction

[0015]One aspect the present subject matter is a method of processing toothbrush bristles using synthetic bristles for obtaining round-shaped toothbrush bristles comprising: cutting one end of a filament bundle of synthetic bristles; mechanically polishing the cut end of the filament bundle of synthetic bristles; heat treating the polished end of the filament bundle of synthetic bristles; and caustisizing the heat-treated end of the filament bundle of synthetic bristles into a round shape.

[0016]In one embodiment, the synthetic bristles may comprise a polyethylene terephthalate resin or a polybutylene terephthalate resin. In another embodiment, the one end of the filament bundle of synthetic bristles, in causticizing, may be dipped to a depth of 3 mm or less in an alkali solution.

[0017]Another aspect of the present subject matter is to provide tooth brush bristles made of synthetic bristles and having at least one end thereof round shaped by caustisizing. These toothbrush bristles ha...

Abstract

Disclosed herein is a method of processing rounded toothbrush bristles using synthetic bristles. The method includes cutting one end of a filament bundle of synthetic bristles, mechanically polishing the cut end of the filament bundle of synthetic bristles, heat treating the polished end of the filament bundle of synthetic bristles, and caustisizing the heat-treated end of the filament bundle of synthetic bristles into a round shape. In this method, at least one end of the toothbrush bristle is softly rounded to protect gum damage due to irritation of the one end of the toothbrush bristle and to provide a gum massaging effect for healthy gum with the rounded end of the toothbrush bristle.

Description

CROSS-REFERENCE[0001]This is a National Phase Application filed under 35 U.S.C. 371 as a national stage of PCT / KR2009 / 004758, filed on Aug. 26, 2009, an application claiming the benefit of priority to Korean Patent Application No. 10-2009-0052323, filed Jun. 12, 2009, the content of each of which is hereby incorporated by reference in its entirety.BACKGROUND[0002]1. Field[0003]The present subject matter relates to round toothbrush bristles and a processing method thereof. In particular, the present subject matter relates to round toothbrush bristles and a processing method thereof to protect gum damage due to irritation by the one end of the toothbrush bristle and to provide a gum massaging effect for improving gum health.[0004]2. Related Art[0005]A variety of fine bristle toothbrushes are available on the market. FIG. 1 shows a conventional fine bristle toothbrush, in which some bristles are processed to have a tapered tip as shown in (A) and others are cut to have a blunt end as s...
