    Abstract: A toothbrush comprises a plurality of bristles, each of which comprises an upper part and a lower part, wherein toughness of the lower part is smaller than the toughness of the upper part, an enrooting member into which the bristles are enrooted, wherein the enrooting member comprises a plurality of enrooting holes that receive the plurality of bristles, wherein each of enrooting hole comprises an enrooting recess that receives the lower part of the bristle. A method of manufacturing a toothbrush comprises steps of cutting a predetermined length from a plastic wire; processing the cut wire into a bristle having an upper part and a lower part, wherein toughness of the lower part is smaller than the toughness of the upper part; and enrooting the bristles into a plurality of enrooting holes of the enrooting member.

    Abstract: The present invention relates to a method of manufacturing a needle-shaped bristle having a short taper length. The method includes preparing a bundle of toothbrush bristles by mixing a polyester resin (a polyester resin other than a PTT resin) and a PTT resin in a ratio of 90˜40 to 10˜60 and spinning the mixture thereof; cutting the bundle of toothbrush bristles; and tapering the cut bundle of toothbrush bristles by immersing it into a chemical. According to the present invention, since needle-shaped bristles having a taper length of 6 mm or less can be efficiently obtained, the needle-shaped bristles can be implanted even in an anchorless toothbrush.

    Abstract translation: 本发明涉及一种具有短锥度长度的针状刷毛的制造方法。 该方法包括通过将聚酯树脂（除PTT树脂之外的聚酯树脂）和比例为90〜40〜10〜60的PTT树脂混合，并纺出其混合物来制备一束牙刷刷毛; 切割一束牙刷刷毛; 并通过将其切入化学品而使切割的牙刷刷毛束变细。 根据本发明，由于可以有效地获得具有6mm以下的锥形长度的针状刷毛，因此即使在无锚式牙刷中也能够注入针状刷毛。

    Abstract: 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-fold, and the loss of raw materials is greatly decreased because several processes are not performed.

    Abstract: A toothbrush having needle-shaped bristles on the head portion is configured such that the differences in height between the longer and 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 and shorter bristles is 1 to 4 mm. The toothbrush provides 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.

    Abstract: 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.

    Abstract: Methods and machines are disclosed to attach tufts of individual bristles to a toothbrush with a resiliently flexible head, wherein the flexible head may be segmented with joints connecting adjacent segments or it may be angled or curved or combinations thereof, and to then trim such tufts of individual bristles to a desired length--or lengths in the case of brushes with multi-level tufts--and to then round the free ends of the individual bristles in each such tuft. The disclosed method and apparatus require only the modification of conventional toothbrush tufting machines having tuft insertion tools that travel in a defined direction and the modification of conventional trimming machines and methods. In particular, the present invention discloses novel apparatus and a method to hold securely a deformed resiliently flexible curved or angled toothbrush head or a segmented resiliently flexible head at the tufting apparatus in a configuration such that the bristle-receiving holes lie substantially parallel to the direction of travel of the tuft insertion tool, and at the trimming and end rounding portions of a toothbrush finishing machine so that conventional tufting, trimming and end rounding machines and methods can be used in the manufacture of such brushes.
