New measuring method to evaluate the Hand Feel (HF) of Fiber Resources

on .

The TSA – Tissue Softness Analyzer represents a nearly perfect simulation of the human hand and shows excellent results in measuring base tissue and finished tissue products (toilet paper, handkerchiefs, facials). In case of hand sheets made in the lab, the device also convinced in measuring the influence of pulp quality (short fibers), refining or softener. But it was limited until now to measure the influence of different compositions of long and short fibers to the softness of hand sheets, and thus, to predict the haptic quality of tissue products.73

The German company emtec Electronic, which developed the original TSA – Tissue Softness Analyzer, upgraded the device with a new sensor design and Marcel Prinz, now Doctoral student at the University of Applied Sciences in Munich, started his master thesis with several tests with the upgraded prototype of the TSA in 2017. He proved and optimized the new TSA measuring method for hand sheets, which enables the measurement of the influence of different fiber mixes (long and short fibers ratio) to the quality of the hand sheet. By the new sensor design and an improved measuring method it was possible to gain very accurate and reliable results with a good correlation to the expectations and the haptic tests. This available information allows a quality forecast for the actual base tissue and finished product, if a certain fiber mix is used.

The new TSA measuring method opens completely new possibilities in saving costs and resources in the production, and it leads to an efficiency increase in the process and product optimization. Especially pulp mills, research institutes and the R&D labs of tissue mills and chemical suppliers waited for such results. Since the last quarter of 2018, the full upgraded TSA version for such measurements, but also the upgrade of an existing standard TSA, is available.

Also, this year in November, emtec Electronic GmbH will attend the ATIP 2018 in Grenoble in France, together with its French representative ODL Paper Service. At exhibition booth no. 2 the company will present a variety of testing instruments by which the complete production process – from the wet end to the finished products – can be controlled and guided in the right direction, to get an efficient process and the best possible quality with the lowest possible costs. To meet steadily the changing demands and requirements in the paper and board industry, the focus is again on further developments and innovations.FPA touchCAS touch Website

Displayed at the booth will be the state-of-the-art CAS touch! to measure the particle charge and the FPA touch! to measure the surface charge of fibers (zeta potential). Both devices help to get information about the efficiency of the chemicals, which are added during the paper, board and tissue production.

Besides this, the EST12 emtec Surface & Sizing Tester is shown. A device to determine important and for the converting relevant paper surface properties such as surface hydrophobia / sizing as well as the surface porosity, which influence printability, coatability and gluability of paper and board.

The ACA Ash Content Analyzer enables the determination of the mineral filler content without combustion, that means without destruction of the samples, within seconds. Both, the total mineral filler content, as well as the individual filler components (e.g. calcium carbonate, kaolin/talcum, titanium dioxide, iron oxide) and their percentage distribution are given.

Especially for tissue and nonwoven products, the TSA Tissue Softness Analyzer gives reliable and objective information about the three basic parameters, which determine the human feeling, the softness, roughness and stiffness. From these three, an overall hand feel value can be calculated. The availability of the three individual parameters opens a huge amount of chances for the optimization of the tissue production and converting processes.

For the 15th time, the international exhibition PAP-FOR 2018 will take place in St. Petersburg, Russia from November 13th to 16th. The German company emtec Electronic GmbH will attend together with the Russian representative Sigma Micron International Ltd. An interesting selection of their innovative testing instruments for the pulp, paper, tissue, converting and packaging industry is shown at booth no. E39 in pavilion F.1

The latest innovation, the ACA Ash Content Analyzer enables the determination of the mineral filler content of a paper or board within seconds and without combustion, that means without destruction of the samples. Both, the total mineral filler content, as well as the individual filler components (e.g. calcium carbonate, kaolin/talcum, titanium dioxide, iron oxide) and their percentage distribution are measured.

Besides this, the well-known EST12 emtec Surface & Sizing Tester will be displayed at the booth. This device is used to determine important paper surface properties such as surface hydrophobia / sizing as well as the surface porosity, which influence printability, coatability and gluability of paper and board.

The availability of the three individual parameters opens a huge amount of chances for the optimization of the tissue production and converting processes.

Furthermore, the smallest and lightest state-of-the-art devices for the wet-end are presented in St. Petersburg. The CAS touch! measures the particle charge and the FPA touch! measures the surface charge of fibers (zeta potential). Both devices help to get information about the efficiency of the chemicals, which are added during the paper, board and tissue production.
