A Study of the Factors Affecting the Separation Force of Artificial Leather Laminating Process

Abstract

The separation force is one of the most important properties of artificial leather industries. This paper aims to determine an optimal setting of artificial leather laminating process in order to obtain the desired separation force. There are three potential factors directly influence the separation force for both machine direction (MD) and transverse direction (TD). These factors are take-off temperature, heating temperature, and embossing pressure. To study the effect of these factors on the separation force, a 23 factorial design with six replicates is then conducted, and the result is analyzed at a significant level of 0.05. The result shows that all main factors have significant effects to MD and TD. The optimal setting of the laminating process for artificial leather to obtain the desired MD and TD is that using take-off temperature, heating temperature and embossing pressure at 175°C, 150°C and 40 Bar respectively.
