Abstract

Several brush assemblies are disclosed. All employ bristle strings that include a base string connected to a plurality of monofilaments. The preferred monofilaments are nylons and other polymeric thermoplastic materials. The monofilaments may be linear segments or loop segments disposed in two rows. The bristle strings may be connected to brush bodies to form virtually any of the various types of brushes. Bristle strings employing loops may be braided together to form entangled, monofilament articles for brush or other applications.
