The ratio can be anywhere from 0% to 100%.

  In a further aspect of the invention, the inner region of the hair bundle has a greater pack density than the outer region of the hair bundle.

  In a preferred embodiment of the invention, the inner region of the hair bundle is more tightly packed compared to the outer region of the hair bundle, for example for more hair bundles per unit area. The length of the tuft can affect the tuft density, as can the force on the brush head to maintain the tuft morphology in place, such as by a crimper or ferrule. The packing density of the bristle bundle itself can be achieved during the manufacturing process by having more bristle in some areas than other areas in the brush head, but need not be.

Beading of liquid (BEADING)
In another aspect of the invention, the inner area of the hair tress is not as wet as the outer area of the tress.

  Wettability refers to the ability of a liquid to be absorbed into a surface, such as the inner and outer regions of a brush head. Preferably, the wettability of the inner area is lower than that of the outer area, so that the liquid material provided to the inner area "beads up" or is otherwise absorbed into the hair tress at that location. Therefore, it would be further available for application to a subject at the site of application.

  Wettability, in some instances, relates to the physical properties of the surface and the liquid applied to it, and can be measured by determining the contact angle. In one example, a hydrophilic liquid applied to a hydrophobic surface beaded on the surface and therefore has a relatively high contact angle compared to the contact angle of the hydrophilic liquid on the hydrophilic surface Will. In some instances, there is no contact angle when the liquid is absorbed to the surface, such as a drop of water applied to a cellulose filter paper or household tissue paper or paper towel. Determination of contact angles is well known in the art of materials science and can select materials and liquids, where the liquid is beaded on the surface or absorbed into the surface.

  In the present invention, the tuft density described herein also appears to be related to the wettability of the brush head, such as in the interior area. The surfaces can be coated or otherwise chemically modified to change their physical properties, such as hydrophobicity and hydrophilicity, and thus the desired wettability and / or beading The material can be selected or modified such that the coating is obtained for a particular liquid applied to the surface, such as the interior region of the brush head of the present invention.

  In a preferred embodiment of the invention, the wettability of the inner area is lower than the wettability of the outer area, so that materials such as liquid applied to the inner area are not absorbed into that area of the brush. The outer region is preferably more wettable with respect to a material such as a liquid applied to the inner region.

  In a further aspect of the invention, the inner area of the hair tress is larger or smaller in contact with the liquid, aqueous solution, polar solution, non-aqueous solution, non-polar solution, emulsion, or a combination thereof than the outer area of the hair tress. With horns.

  In a further aspect of the invention, the inner region of the hair tress is less or more wet than the outer region of the hair tress with respect to aqueous solutions, polar solutions, polar liquids, or combinations thereof.

  In another aspect of the invention, the inner region of the hair tress is not as wet as the outer region of the hair tress with respect to a non-aqueous solution, a non-polar solution, or a non-polar liquid, or a combination thereof.

  In a further aspect of the invention, the inner area of the hair tress is not as wet with respect to the emulsion as the outer area of the hair tress.

  In a further aspect of the invention, the interior region of the bristle bundle forms a reservoir for a material, such as, but not limited to, a liquid material. As the material is applied to the surface, the interior region of the hair bundle can inherently provide additional material for additional and sustained application of the material.

  In another aspect of the invention, the interior region of the hair tress may be partially wettable with respect to materials such as, but not limited to, liquid materials. This aspect of the invention is preferred when the interior region of the hair tress acts as a reservoir for the material. In this example, the material can "sink" into the interior area of the hair tress and is still available for application to the surface.

Rubbing In another aspect of the invention, the outer region has a higher rubbing characteristic, a reduced fringing characteristic, or a combination thereof than the inner region.

  In a preferred embodiment of the invention, during operation, therefore, the inner region effectively holds the material in place for application to the surface, and the outer region provides the material on the surface for the desired effect. It acts to smooth or rub the application. A preferred desired effect is the reduction of material streaks or stains when applied to a surface, such as, but not limited to, liquid cosmetics applied to a human subject.

  However, in certain instances, the invention also includes such aspects, such as for artistic purposes where stripes or stains have a desired effect. Such examples may be, for example, hobby paintings and other artistic expressions where incomplete mixing, streaks, shading, feathering, etc. are more desirable than a smooth, rubbed appearance.
