摘要:
A modified fiber of the present invention has high abrasion resistance under wet conditions and high washing resistance. The modified fiber is a modified fiber in which an epoxy compound is bonded to a refined cellulose fiber, a natural cellulose fiber, cuprammonium rayon, rayon, or a silk fiber, the epoxy compound being at least any one of resorcinol diglycidyl ether and hydroquinone diglycidyl ether.
摘要:
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.
