In one aspect, a composition for treating fibers comprises an acidic aqueous or aqueous-based continuous phase and a liquid repellent phase comprising a dendrimer component and/or non-dendrimer alkyl urethane. The treatment composition, for example, can have pH of 2.5 to 6.5. In some embodiments, carboxylic acid is employed in the treatment composition for providing the acidic character of the aqueous or aqueous-based continuous phase. Moreover, the treatment composition can further comprise at least one of an acid stain resist component and soil release component. In some embodiments, fibers treated with compositions described herein exhibit ionic character.

A human hair fiber treatment agent comprised of one or more compositions for treating human hair fibers having free ends at both ends, wherein the human hair fiber treatment agent comprises the following components (A) to (C) in the formulation thereof: (A): at least one formaldehyde derivative selected from the group consisting of formaldehyde, and the like; (B): phenol compound(s) having electron-donating group(s) on at least one of the meta positions and having hydrogen atom(s) on at least one of the ortho positions and the para position, with the proviso that the electron-donating group at the meta position optionally forms, together with a carbon atom attached thereto, a benzene ring optionally substituted with hydroxy group(s); and (C): water.

A rubber-reinforcing cord (12) of the present invention includes at least three strands. Each of the strands includes at least one filament bundle and a first coating provided to cover at least a portion of the surface of the filament bundle. The filament bundle consists essentially of aramid fiber filaments. The mass of the first coating is in the range of 14 to 25% with respect to the mass of the filament bundle. Each of the strands is given primary twists at a primary twisting rate of 50 to 100 twists/m. The at least three strands each given primary twists are assembled and given final twists at a final twisting rate of 120 to 200 twists/m.
