Research on improving the basis weight measurement accuracy of tissue paper based on PSO-BP neural network, TAPPI Journal October 2022

ABSTRACT: The near-infrared (NIR) sensor can be used for measuring the basis weight and moisture of tissue paper, but the measurement accuracy is not ideal for this paper grade. The weight range of the tissue is 10~30 g/m2, indicating that it is a low gram weight paper. The temperature and humidity of the production environment significantly impact an NIR sensor. This paper focuses on improving the measurement accuracy of tissue paper basis weight. In order to reduce the influences of temperature and humidity, a mathematical model based on a particle swarm optimization back propagation (PSO-BP) neural network is proposed. In comparison with multiple linear regression measurement models, the basis weight measurement error with the PSO-BP model is within ± 0.5 g/m2. This model can effectively improve the measurement accuracy and has a good effect on overcoming the basis weight nonlinear effect caused by the changes in ambient temperature and humidity.

An experimental method to study the absorption capacity of paper towels, TAPPI Journal April 2021

ABSTRACT: This study proposes an experimental method for the in-plane liquid wicking to determine the absorption capacity of retail paper towels. Individual plies of the paper towels were tested to minimize the transverse wicking effects on surface wetting. The method involves arbitrary point source injection of liquid into the paper towel surface while recording microscopic images of the wetted areas as liquid spreads. The samples were selected from two main manufacturing processes: conventional wet pressing and through air drying. The tested liquids were water and decane with various driving forces. Two distinct imaging systems, infrared light absorption imaging and visible light transmission imaging, monitored and recorded the wetting process. The wetted regions were calculated to generate the wetting graphs, which illustrate both the dynamic and static wetting behaviors. It was found the amount of driving force has a negligible effect on the maximum wetted area formed on the surface. So, the maximum wetted area and the paper grammage were applied to determine the absorption capacity of the tested towels. Moreover, the absorption capacity results were validated by the basket-immersion test method (ISO 12625-8). Therefore, the proposed method in this work enables quantification of the absorption capacity of paper towels.
