Domtar raises the bar for fluff pulp quality

Domtar’s Plymouth mill has continuously improved its quality performance after an NC5 machine rebuild and the installation of a Valmet QCS and cross-direction profilers. The 306 inch (7772 mm) trim machine NC5, originally a fine paper machine, was rebuilt by Valmet to produce fluff pulp. With dilution control actuators on the headbox and a steam profiler just before the couch, the machine was ready-built for precise CD quality control. After a technical evaluation, a new Valmet IQ quality control system was purchased to provide the essential dry weight and moisture measurements and to close the loop on the CD and MD controls.
