Tissue softness is a property that all manufacturers attempt to control, either to produce the highest quality tissue or to produce a level of softness at a specific cost. Softness can be enhanced by changing the furnish used or by changing the tissue machine operation. Alternatively, sheet softness can also be enhanced downstream of the tissue machine using treatments applied to the surface of the sheet. Choosing the most cost effective approach for achieving the desired level of softness is complicated by the problem of quantifying the improvement in softness. Panel testing is the method most commonly used to evaluate softness; however, this method generally only provides a qualitative result.
