Title: Innovations of Robert L De Jong
Introduction
Robert L De Jong is a notable inventor based in Appleton, Wisconsin, with a significant contribution to the field of papermaking and recycling. He holds five patents that showcase his innovative approaches to improving processes in these industries. His work has had a lasting impact on the efficiency and effectiveness of recycling methods.
Latest Patents
One of his latest patents is a method of measuring macro and micro stickies in a recycled sample containing pulp fibers. This method involves forming a slurry of recycled macro stickies and a liquid, using a first separation device to separate the macro stickies from the pulp fiber while collecting the screenate. The macro stickies and pulp fibers are then washed with additional liquid to further separate any remaining macro stickies. The macro stickies are measured after being removed from the first separation device. Additionally, the method includes agglomerating micro stickies in the screenate to form agglomerated micro stickies, which are then separated and measured using a second separation device.
Another significant patent by De Jong is a method of curling fiber and absorbent sheets containing the same. This method provides papermaking fibers with a durable curl by introducing the fibers into a rotatable drum operating at elevated pressure. The drum maintains the fibers in an aqueous dispersion while rotating, allowing the mechanical action to impart a durable curl to the fibers. The process is carefully controlled to ensure that the treated fibers exhibit a curl elevation of at least 50 percent after one hour of storage.
