Provided is a method for manufacturing a sheet for use in a tongue plaque cleaner, capable of reliably cutting loops of thread members provided at a given density, and forming thread members each having a shape with an arc portion sufficient enough to scrape off tongue plaque, through steps that are simple, low-cost and suitable for mass production. A method for manufacturing a sheet 1 for use in a tongue plaque cleaner for scraping off tongue plaque, includes: a step of heating a sheet material having multiple looped thread members 2 protruding from one surface of the sheet material, at a temperature below the melting point of the thread members 2; and a step of forming first thread members 3, 8 and second thread members 4, 9 by cutting loops of the thread members 2 heated.

A broom and a manufacturing method thereof, the broom comprising at least a broom handle (1) and a broom core; the bottom of the broom handle (1) is provided with a transverse plate (2); the broom core is fixed on the transverse plate (2), and comprises more than one bundle of brushes; the brushes are provided with dispersed slender resilient strips (9) thereon for cleaning the ground; the resilient strips (9) take up more than ½ the length of the brushes; the side surface of the resilient strips (9) is arc-shaped, and tapers from top to bottom; the bottom end of the resilient strips (9) is a thickened layer. The brushes of the broom are made by cutting waste beverage bottles, solving the problem of environmental pollution caused by the waste beverage bottles; the manufacturing method is simple, thus reducing the production cost; the bottom end of the resilient strips (9) is a thickened layer (7), thus significantly improving wear resistance and stability and greatly extending service life compared to a bamboo broom.

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.
