    摘要： Disclosed is a toothbrush having soft and hard bristles together. The toothbrush having soft and hard bristles with 6-10mm in tapered length and 0.01 - 0.08mm in diameter of end portions comprises: longer bristles(1) located at both edges; and shorter bristles(2) located at the central portion, wherein the bristles are generally in a semicircular form at their top portions when seen from a side, and a difference in length between the longer bristles(1) and the shorter bristles(2) is about 2 - 4mm. The toothbrush can increase brushing efficiency and effectively remove foreign matters between teeth and inside periodontal pockets.

    摘要： The present invention provides a method of tapering bristles for toothbrushes and a toothbrush having bristles manufactured using the method. One method disclosed in the present invention includes setting bristles made of polyester in a head insert (10), and fastening the bristles to the head insert (10) by thermally welding portions of the bristles, protruding from a back surface of the head insert, to the head insert (10). The method further includes coupling the head insert (10), to which the bristles are fastened, to a toothbrush body (1), and tapering ends of the bristles by immersing the bristles in a chemical. In the present invention, the bristles can be securely set in the toothbrush body (1) without anchor. Furthermore, polyester bristles, which could not be set in toothbrushes having variously shaped setting rows due to excessively high stiffness, can be set in these types of toothbrush by the toothbrush manufacturing method of the present invention.

    摘要： The present invention relates to a method of tapering a toothbrush bristle which increases production efficiency. The method includes the steps of cutting bundles of toothbrush bristles; and non-directionally immersing the entire cut bundles of toothbrush bristles into a chemical solution to taper both sides of the toothbrush bristles. According to the present invention, the production efficiency of a needle-shaped bristle is increased approximately three times, and the loss of raw materials is greatly decreased because several processes are not performed.

    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.
