Wet strength in tissue and towel products is traditionally achieved by using relatively high dosages of a wet strength resin (WSR). This puts a substantial pressure on the tissue maker’s profitability both due to high chemical cost and due to negative effects from WSR on machine runnability such as foaming, felt deposits and reduced dewatering.
In recent years, tissue makers have also been under pressure to reduce the AOX levels in their effluent, to which WSR can be a significant contributor. Thus, there is an acute need for economically effective solutions for reducing the WSR consumption.
Kemira has developed innovative chemical solutions to provide economic and environmental advantages in the production of wet-strengthened paper grades.
