Abstract: According to an aspect of the invention there is provided a method of manufacturing an applicator brush for use in applying a product, such as a cosmetic product, the method comprising providing a plurality of fibers, decorating the fibers so as to define at least one colored region, and fitting the decorated fibers to a stem so as to define a cosmetic applicator brush, wherein the step of decorating the fibers includes a step of coloring the fibers using dye sublimation so that individual fibers have an outer colored region and an inner uncolored region. In an embodiment, an individual fiber is decorated with a color that is different to another individual fiber extending from the stem. Alternatively, or in addition, an individual fiber is decorated with at least two colors.

Abstract: An applicator brush includes a stem, and a plurality of bristles supported by the stem. The stem extends from an end of a rod and includes a first branch and a second branch twisted together, each branch having a non-circular cross-section The bristles are positioned between the twisted first and second branches. In some embodiments, each branch includes a plurality of strands pre-twisted together to create the non-circular cross-section of each branch, forming a multi-helicoidal stem.

Abstract: The present invention provides a non-contact process for decorating dye-permeable fibres of a cosmetic applicator. The process comprises heating a dye-carrying surface of a carrier medium to a temperature sufficient to cause a dye plume to be released from said dye-carrying surface. The process further comprises placing said dye-permeable fibres of the cosmetic applicator at a distance from said dye-carrying surface in the path of the released dye plume, thereby allowing said dye to penetrate and decorate said dye-permeable fibres. The dimensions and the density of the dye plume can be optimised by controlled air flow. In an embodiment, the process comprises decorating all of the dye-permeable fibres simultaneously. Alternatively, the process comprises decorating only a portion of the fibres, the portion being either radial sections around a core to which the fibres are fitted, or longitudinal sections along the length of the core.
