| titleOfInvention | Continuous papermaking process |
| abstract | ABSTRACT OF THE DISCLOSURE A continuous, essentially closed recirculating papermaking process is provided by using a dispersing me-dium of adjustable viscosity. The process permits the continuous reuse of the medium under preferred operating conditions. It includes the steps of forming a dispersion of fibers within the adjustable medium containing a pH sensitive viscosity producing agent, reducing the fiber consistency and the viscosity within the dispersion while maintaining the concentration of the agent substantially unchanged, subsequently forming a fibrous web material on a papermaking screen from said dispersion of reduced fiber consistency while separating the dispersing media from the fibers forming the web and continuously collecting the sep-arated media and recirculating it within the system to ef-fect a subsequent fiber dispersion as well as a fiber con-sistency reduction and viscosity reduction without substan-tially changing the concentration of the viscosity producing agent. The separated and recirculated dispersing media is capable of forming a high viscosity dispersing media for the fibers at the time of forming the subsequent fiber disper-sion without the addition of more viscosity producing agent. |
