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 and so on. are engineered to achieve specific goals in the paper making process.

The need to implement an effective 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.

Polyester forming fabrics must be kept free of contaminants in order to maintain surface characteristics, adequate open area, and to prevent sheet marking.

Press felts must be cleaned, conditioned, and lubricated in order to maintain void volume, caliper and prevent wear; thus enabling the felt to take water and be dewatered uniformly throughout its operational life.

Finally, Polyester dryer fabrics must be cleaned in order to maintain their permeability and prevent sheet streaking due to non-uniform drying profiles and sheet drop-offs in vacuum assisted transfers, uniron and single tier dryer runs.

The cleaning of Paper machine clothing is accomplished by mechanical (showering) or chemical means. An effective cleaning system can employ both methods on a continuous and/or batch basis and is designed to prevent unwanted side-effects such as streaking and fabric damage due to plugged shower nozzles or improper operation of high pressure showers.
