Painting Brush

Abstract

The chemical-fiber-made brush is capable of providing sufficient amounts of coating material picked up and released to improve the working efficiency of the coating operation. The brush is provided with bristles 1 made up of a bundle of chemical-fiber monofilaments including wavy monofilaments. By mixing wavy monofilaments and non-wavy monofilaments, the amount picked up can be increased as compared with the case of bristles made up of non-wavy monofilaments, and the spreading out of the leading ends of the bristles can be prevented as compared with bristles made up of wavy monofilaments alone.

Description

BACKGROUND OF THE INVENTION [0001] This invention relates to a painting brush used for applying a coating material. DESCRIPTION OF THE RELATED ART [0002] Typically, conventional painting brushes use as their bristles chemical fiber monofilaments outstanding in quality, stability of supply and the like. Such conventional brushes using chemical fibers have bristles made up of straight monofilaments alone. [0003] However, the conventional brush having straight bristles alone as described above can pick up and hold only a small amount of coating material. This may be the reason that, in the straight bristles, the monofilaments come into close contact with each other and so reduce the space for holding the coating material between monofilaments. [0004] In such a brush, a small amount of the coating material picked up naturally results in a reduced amount of release, which in turn gives rise to the need of repeatedly dipping the brush into the coating material many times for applying the ...

AI Technical Summary

Benefits of technology

[0007] It is an object of the present invention to provide a painting brush capable of maintaining excellent bundling of bristles, of ensuring that a satisfactory amount of coating material will be picked up and held and a satisfactory amount released, and of offering outstanding working efficiency in the coating operation.

[0011] According to the present invention, the mixing of straight monofilaments and wavy monofilaments makes it possible to increase the amount of coating material picked up while maintaining excellent bundling of bristles. As the amount of coating material picked up increases in this manner, the amount of coating material released increases, resulting in improvement in working efficiency of the coating operation.

Problems solved by technology

However, the conventional brush having straight bristles alone as described above can pick up and hold only a small amount of coating material.

In consequence, the problem of extremely inferior working efficiency arises.

However, the formation of the recesses in the surface of the straight bristles cannot allow a satisfactory amount of the coating material to be picked up.

In either case, the conventional painting brushes having straight bristles alone have the problem of the incapability of ensuring that a sufficient amount of coating material will be picked up.
