Abstract
Bristle tuft assemblies and associated fabrication methods are disclosed. One disclosed bristle tuft assembly comprises a bristle tuft, a retention material and a support surface. The support surface is permeable to the retention material when the retention material is in a molten state. The retention material is fused into the support surface. The bristle tuft is connected to the support surface via the retention material.

A bristle tuft assembly comprising:
- a bristle tuft;
- a retention material;
- and
- a support surface that is permeable to the retention material when the retention material is in a molten state;
- wherein:
- (i) the retention material is fused into the support surface;
- and (ii) the bristle tuft is connected to the support surface via the retention material.

A method for forming a bristle tuft assembly, the method comprising:
- transitioning a retention material to a molten state;
- permeating a support surface with the retention material, when the retention material is in the molten state;
- fusing the retention material into the support surface;
- and
- whereby:
- (i) the retention material is fused into the support surface;
- and (ii) a bristle tuft is connected to the support surface via the retention material.
