Since softness is a key consumer purchasing characteristic of value-added tissue products, the challenge has always been how to measure it. To answer this, we need to understand what we mean by hand-feel. It’s a combination of multiple elements such as real softness, smoothness, stiffness, and compressibility.
In the past an assessment of softness used to be determined by an experienced panel of people. This test was time-consuming, and the results could be highly subjective. Over time, progress has been made and advanced new monitoring instruments have given us the ability to quantify tissue softness quickly, accurately, and cheaply. The results correlate closely to human testing and provide numerical data for QC and Marketing use. Factors such as culture, personal preferences, and personality can now be eliminated. However, it’s clear that Softness panels and HUT (home user tests) will always remain. Consumers are human after all and not machines.
Your challenges, our mission
The perceived softness of the tissue is controlled by many factors including fibre selection, formation and creping, as well as the external use of chemicals (e.g. surface conditioners) to enhance quality. The secret lies in the correct combination of chemistries, in the right place in the process and complemented by advanced analytical techniques. With our unique knowledge of pulp, papermaking and converting, BIM is the perfect partner in developing sustainable tissue solutions.
