Applicator brush having decorated fibers and associated method of manufacture
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.
1. A method of manufacturing an applicator brush, 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 an applicator brush,
wherein the step of decorating the fibers includes a step of coloring the fibers by dye sublimation so that individual fibers have an outer, colored region and an inner uncolored region.
2. The method according to claim 1 , wherein the outer colored region is the result of color infiltration up to radial depth of approximately 20 μm.
3. The method according to claim 1 , wherein the step of decorating the fibers results in at least two distinctly colored regions.
4. The method according to claim 1 , wherein the step of decorating the fibers includes a step of decorating an individual fiber with a color that is different to another individual fiber for the same brush.
5. The method according to claim 1 , wherein the step of decorating the fibers includes the step of decorating an individual fiber with at least two colors.
6. The method according to claim 1 , wherein the step of providing a plurality of fibers includes a step of providing a multiplicity of fibers, and a step of fitting the decorated fibers includes the step of radially fitting the multiplicity of fibers to the stem.
7. The method according to claim 1 , wherein the step of decorating the fibers includes a step of distinguishing the at least one colored region so that when fitted to the stem, the at least one colored region is distinguishable axially along the length of the stem, radially relative to the stem or circumferentially around the stem, or a combination of these.
8. The method according to claim 1 , wherein the step of using dye sublimation includes a step of bringing the fibers into contact with a carrier medium carrying a dye to be transferred and applying heat to the carrier medium.
9. The method according to claim 8 , wherein the method comprises printing the dye according to a pattern that corresponds to the at least one colored region.
10. The method according to claim 9 , wherein the carrier medium is sandwiched between a heated cylinder or a heated platen and a backing.
11. The method according to claim 10 , wherein the backing is also heated.
12. The method according to claim 8 , wherein the carrier medium is paper and the dye is contained in ink printed onto the paper.
13. The method according to claim 1 , comprising bundling a plurality of fibers and decorating the bundled fibers so as to define the at least one colored region.
14. The method according to claim 1 , wherein the applicator brush is a cosmetic applicator brush for use in applying cosmetic product.
15. The method according to claim 14 , wherein the cosmetic applicator brush is a mascara applicator brush and the cosmetic product is mascara.
16. The method according to claim 1 , wherein the applicator brush is a toothbrush.
