Problem Summary

Control of dry tensile strength in tissue is critical to ensure good and consistent quality tissue. 

Low tensile strength can lead to a reduction in product quality or result in tissue being downgraded.  If the dry strength is too high, it can mean that softness is reduced or production costs could be too high.  Dry strength control can also help to reduce dusting around the Yankee cylinder and also a reduction in refining levels, which can result in increased machine speeds through improved drainage. 

Consistently achieving the correct dry strength means that quality and production costs are optimized and that good quality tissue will be produced at all times.

Recommended Solution

Hercobond® Dry Strength Technology is a range of synthetic polymers specifically designed to give increased strength.  Products are available to improve the strength properties of toilet grades, facial tissue and toweling grades.  The broad portfolio of Hercobond® dry strength technologies allows the tissue manufacturer to match product chemistry to actual machine conditions and grade requirements to maximize strength improvements without compromising any other sheet properties.

Key benefits recorded from practical applications of Hercobond® Dry Strength Technology include:

Increased dry tensile strength
Improved softness
Reduced dusting
Increased machine speeds and productivity
Reduced reject levels
