    摘要： The present invention provides a needle-shaped bristle and a method of manufacturing the needle-shaped bristle. The manufacturing method of the present invention includes the steps of cutting and removing a packing sheet, which is wound around a bundle of bristles, by a length ranging from 30 mm to 50 mm from a first end thereof, and grinding first ends of the bristles using a rotating grinder. The manufacturing method further includes steps of packing the first end of the bundle of bristles, from which the packing sheet is removed, using a packing sheet, cutting the bundle of bristles to a length ranging from 22 mm to 32 mm, and immersing a second end of the cut bundle of bristles, thus tapering second ends of the bristles. The needle-shaped bristle has an advantage of realizing a reduction in the proportion of defective products.

    摘要： The present invention relates to a toothbrush having needle-shaped bristles on the head portion and is configured in such a manner that the differences in height between the longer bristles and the shorter bristles is 1 to 4 mm, the end points of the longer bristles are 0.01 to 0.03 mm in diameter, the end points of the shorter bristles are 0.03 to 0.08 mm in diameter, the taper lengths of the longer bristles are 4 to 8 mm, the taper lengths of the shorter bristles are 2 to 6 mm, and the differences in taper length between the longer bristles and the shorter bristles is 1 to 4 mm. The toothbrush according to the present invention provides the superior teeth and gum contact force unique to a toothbrush having needle-shaped bristles and at the same time also provides superior cleaning performance for the surface of teeth thanks to the action of the shorter bristles having relatively large diameters at end points and relatively short taper lengths. In addition, the wearing-out of an end portion of the bristles is delayed thanks to the shorter bristles so that the effect of prolonging the lifespan of the toothbrush is provided.

    摘要翻译： 本发明涉及一种在头部上具有针状刷毛的牙刷，其构造方式使得较长的刷毛和较短的刷毛之间的高度差为1至4毫米，较长的刷毛的端点为 直径0.01〜0.03mm，短毛的端部直径为0.03〜0.08mm，长毛的长度为4〜8mm，短毛的长度为2〜6mm， 较长的刷毛和较短的刷毛之间的锥形长度的差异为1至4mm。 根据本发明的牙刷对具有针状刷毛的牙刷提供独特的优异的牙齿和牙龈接触力，同时还由于较短的刷毛具有相对较大的作用而对牙齿表面提供优良的清洁性能 端点处的直径和相对较短的锥形长度。 此外，由于刷毛较短，刷毛末端部分的磨损被延迟，从而提供了延长牙刷使用寿命的效果。
