A spiral bristle (201) includes: a first component (231), a second component (233), and a third component (235), with each of the second and third components (233, 235) wrapping around the first component (231) in a helical and spaced-apart manner, the second and third components (233, 235) isolated from one another by the first component (231). An oral care implement includes the spiral bristle.

The present invention relates to mascara for eyelash makeup and, more specifically, to mascara for eyelash makeup, which is produced by winding a brush band around a brush shaft in a spiral form and then coupling the brush band to the brush shaft.

A bristled component for a cosmetic applicator comprising: an elongated carrier having a longitudinal axis; and at least a first plurality of bristles including at least one array of bristles ultrasonically welded to the carrier and outwardly extending therefrom according to a first pre-determined pattern, wherein the carrier and the bristles comprise ultrasonically compatible materials, and wherein the bristles are ultrasonically bonded to the carrier through a direct ultrasonic bond between a surface of the carrier and a lengthwise portion of each of the bristles. A process comprises wrapping a yarn around a moving endless band, juxtaposing a support strip with the band's edge, ultrasonically welding the yarn to the first support strip, removing the welded yarn and support strip from the band, and cutting the strip into a plurality of bristled components.

Provided are a toothbrush in which a tapered surface is formed on a tip part of synthetic resin fibers forming a brush and a fiber surface including the fiber tip part is coated with minerals and the toothbrush is provided with a bristle tip (fiber) having appropriate bending strength, and a manufacturing method of the toothbrush. The toothbrush 1 includes a brush in which a mineral component layer is formed on a surface of a synthetic resin fiber 4. The synthetic resin fiber 4a having a tapered surface 4a1 which is formed in a range of 1 mm to 8 mm from a tip occupies 90% or more of the synthetic resin fibers 4 (4a, 4b), and bending strength of the brush at a position of 1 mm from a leading edge of the brush 3 (the synthetic resin fibers 4 (4a, 4b)) is 0.60 N/cm.sup.2 to 2.00 N/cm.sup.2.

Disclosed are a no-glue cosmetic brush and its manufacturing method. The manufacturing method of the no-glue cosmetic brush of the present invention includes the steps of forming a shape of a brush hair by using a plurality of hair members; providing a fusion portion by applying heat to a lower end of the shaped brush hair; processing the brush hair in a desired shape by pressing a hair fixing tube in a region to which the fusion portion is inserted; and coupling the brush hair to the hair fixing tube by pressing the hair fixing tube after inserting the brush hair to the hair fixing tube.
