Background

Papermaking felts are one of the most important components of modern paper machines, primarily for sheet formation and transport. The blanket can be polluted to different degrees in the production and use processes, and the necessary and reasonable cleaning and maintenance are very important. Carpet contaminants mainly include two types: 1. the adhesive pollution is mainly caused by the fact that resin and various organic synthetic auxiliary agents in the slurry are adhered to the surfaces of fiber raw materials and fillers or are dissociated in the slurry to cause deposition and adhesion; 2. fine fibers, fillers, etc. clog the blanket.

In the papermaking process, the pollution of the papermaking felt is accelerated due to the reasons of using a large amount of regenerated fibers, increasing the use amount of various fillers, using a large amount of chemicals and implementing white water closed circulation under the pressure of environmental protection. The felt with serious pollution greatly reduces the dewatering efficiency of the press part, brings adverse effects to the operation of paper making and paper machines, increases the steam consumption of the drying part, generally does not have mechanical wear but can be taken off due to pollution, dirt adhered to the surface of the felt and accumulated in the felt can be removed through washing in production, the elasticity and the bulk of the felt are recovered, and good drainability, water content and air permeability are maintained, so that the service time of the felt is prolonged, the normal operation of the paper machine is ensured, the yield and the quality are improved, and the consumption of the felt is reduced.

The existing washing mode is not ideal for the cleaning effect of the blanket after being heavily polluted by the sticky substances, and the expected cleaning effect can not be achieved even if the using amount of a cleaning agent is increased or the cleaning time is prolonged. Meanwhile, the wool fibers are damaged, the service cycle of the blanket is influenced, and the blanket can be replaced by a new blanket in serious cases, so that the production cost is increased.
