FPInnovations research finds way to reduce tissue linting with aspen kraft

October 2, 2018 – FPInnovations researchers have found that the tissue linting associated with soft tissue products can be reduced by replacing part of eucalyptus pulp with aspen kraft, according to the results of new trials conducted by the organization.

Daniel Ricard, manager of the FPInnovations pilot tools, will present the results at the TAPPI RISI Tissue 2018 Conference and Expo.

The conference, which is the only non-commercial peer-review tissue event in North America, takes place in Appleton, Wisconsin from October 2-5. Ricard will give a presentation titled, "The use of aspen kraft as part of tissue furnish to reduce linting."

"Eucalyptus pulp is widely used in tissue-making because of its good bulk and softness,” explains Ricard. “But tissue dusting and linting is a growing issue for consumers because tissue makers are pursuing higher bulk and softness. Our research shows that aspen kraft can be an effective means of reducing tissue linting."

FPInnovations researchers Ricard, lead scientist Ho Fan Jang and principal technologist Tony Manfred ­­co-authored the research, which progressively replaced eucalyptus pulp with aspen kraft while maintaining the softwood constant.

The objective of the study was to explore the causes of tissue dusting and linting and develop strategies to minimize the issue.

Ricard will be joined at Tissue 2018 by Chris Kanters, national director, intellectual property, contracts and licensing. The conference is hosted by the Technical Association of the Pulp and Paper Industry (TAPPI) and RISI, an information provider for the global forest industry.
