Method to measure and/or adjust combing resistance by using a brush

Abstract

Disclosed herein is a method to measure and / or adjust combing resistance of fibers by using a brush, wherein the brush comprises: a brush handle; a brush head connecting to the brush handle and comprising a substrate and bristles which are mounted on the substrate, wherein a certain number of the bristles are movable; an activation means which moves the movable bristles from their original positions to different positions; wherein the brush further comprises at least one of the following: a cover for the brush head which is movable between an open position and a closed position, which internal surface can closely face to the tips of the bristles in its closed position, and which has a gap between the substrate and its side ends in its closed position; an indication to match at least one position of the movable bristles to at least one fiber type and / or at least one treatment type; or the combination thereof. By the use of the above brush device, it becomes easier to measure and / or adjust combing resistance of a variety of fiber types.

FIELD OF THE INVENTION[0001]The present invention relates to a method to measure and / or adjust combing resistance of fibers by using a brush, wherein the brush comprises: a brush handle; a brush head connecting to the brush handle and comprising a substrate and bristles which are mounted on the substrate, wherein a certain number of the bristles are movable; an activation means which moves the movable bristles from their original positions to different positions; wherein the brush further comprises at least one of the following: a cover for the brush head which is movable between an open position and a closed position, which internal surface can closely face to the tips of the bristles in its closed position, and which has a gap between the substrate and its side ends in its closed position; an indication to match at least one position of the movable bristles to at least one fiber type and / or at least one treatment type; or the combination thereof. By the use of the above brush devi...

AI Technical Summary

Benefits of technology

The patent describes a brush with a movable cover that can be opened and closed. The cover is designed to closely face the tips of the bristles when closed, and there is a gap between the brush and the sides when closed. This allows for easier measurement and adjustment of combing resistance for different fiber types. The brush has improved sensitivity to detect differences in combing resistance for different fiber types.

Problems solved by technology

Keratinaceous fibers, particularly human hair fibers, may be damaged over time.

Damages may be caused by environmental factors, including air pollution, sun exposure, chlorine from water pool, and / or rain.

Damages may also be caused by applying to the fibers grooming (cosmetic), chemical and / or mechanical treatments.

When hair fibers are damaged, the hair fibers may have undesirable conditions of, for example, “fly-away hair”, “split end”, and / or color fade.

However, it's sometimes difficult to measure differences in combing resistances of the keratinaceous fibers before / after treatments, by a common measurement device for all keratinaceous fiber types.

For example, a comb which is suitable for heavily damaged and / or heavily curled keratinaceous fibers may not be sensitive enough for healthier straight keratinaceous fibers.
