Maintaining clean, open felts is critical to paper machine performance. A 1% increase in sheet dryness leaving the press section generally permits a 3% to 5% increase in production or a comparable energy decrease. A properly designed felt conditioning/cleaning program will optimize felt life and press section performance. Felt conditioners are applied continuously to prevent felt filling and maximize felt life. Felt cleaners are applied in a batch fashion to remove contaminates from the felt and restore their performance.
Felt conditioners and cleaners are formulated based on specific contaminants found in the felt.
The application of felt conditioners is as important as the product selection. Fuyuan has custom designed systems for automated batch, batch-on-the-fly, and continuous applications.
