Modern paper machine clothing is manufactured with a specific set of design and quality specifications for each paper machine’s performance requirements. Such specifications, i.e. surface characteristics, open area, void volume, permeability, smoothness, etc. are engineered to achieve specific goals in the papermaking process. The need to implement an effective PMC cleaning program has become increasingly crucial in recent years. This change is primarily due to increasing levels of recycled furnish, faster machine speeds and accompanying technology, elevated sheet quality requirements, and the desire for longer fabric life. Forming fabrics must be kept free of contaminants in order to maintain surface characteristics, adequate open area, and to prevent sheet marking.
