Abstract
A mascara brush and method of manufacture thereof provides a mascara brush with bristle fibers that are split into numerous fragments. The mascara brush is made with bristle fibers having longitudinal voids. The brush is then conditioned by passing a rotating wire wheel over the bristle fibers . The wire wheel splits the bristle fibers into numerous bristle fragments. The conditioned brush is softer to the touch than the original mascara brush. The conditioning can be applied to the entire brush or one or more zones of the brush. The conditioning can be shallow, so that only the bristle tips are conditioned, or deep, so that a substantial length of the bristle is conditioned.
Claims9
A brush for applying mascara to eyelashes, comprising:
- a straight twisted wire core holding a plurality of radially extending bristles to form a brush at an end of the core, at least some of said bristles having one or more longitudinal hollow voids therein, said brush having at least one first zone which is less than the entire outer surface of the brush and which extends around only a portion of the diameter of an outer surface of said brush and along a length of the outer surface of the brush in said portion of the diameter of the outer surface of the brush, and in which ends of bristles in said at least one first zone have been conditioned by the process of placing ends of the bristles against a rotating wire wheel to split some bristles in said first zone into two or more bristle fragments such that said conditioned bristles have a softer feel and have a larger mascara product carrying capacity than bristle ends which have not been conditioned;
- said brush having at least one second zone which is less than the entire outer surface of the brush and which extends around only a portion of the diameter of an outer surface of said brush and along a length of the outer surface of the brush in which ends of bristles in said at least one second zone are not conditioned such that said unconditioned bristles are stiffer than said conditioned bristles and provide lengthening and combing to a user's eyelashes.
