Abstract
A method for manufacturing a bristle head for a brush is provided. The method includes a first step of obtaining a fiber bundle by reeling up a melt-spun synthetic fiber, a second step of obtaining a unit fiber bundle by cutting the fiber bundle in a direction perpendicular to a longitudinal direction, a third step of forming a tapered shape at a tip portion of each fiber included in the unit fiber bundle, a fourth step of forming a bristle head by isolating a part of the unit fiber bundle, and a fifth step of forming a conductive portion including a conductive material on a surface of each by immersing the bristle head in a treatment bath accommodating a treatment liquid.
Claims5
A method for manufacturing a bristle head for a brush, comprising,
- a first step of obtaining a fiber bundle by reeling up a melt-spun synthetic fiber;
- a second step of obtaining a unit fiber bundle by cutting said fiber bundle in a direction perpendicular to a longitudinal direction;
- a third step of forming a tapered shape at a tip portion of each fiber included in said unit fiber bundle;
- a fourth step of forming a bristle head by isolating a part of said unit fiber bundle;
- and
- a fifth step of forming a conductive portion including a conductive material on a surface of each fiber by immersing said bristle head in a treatment bath accommodating a treatment liquid,
- wherein said treatment liquid is an aqueous solution containing at least one type of metal ion selected from the group consisting of Cu2+, Ag+, and Pd2+, and a reductant agent, or is a plating solution containing at least one type of metal selected from the group consisting of Cu, Ag, and Ni.
