Title: Surface treatment effect in thermoplastic rubber and natural leather for the footwear industry
Issue Date: 2015
Abstract: This paper aims to analyze the peel strength of an adhesive joint with various typesof surface treatments. In the shoe industry, the adhesive properties are very important to ensure the quality of manufacture of the shoe, thus, to better understand thebehaviour of the adhesive joint, it is important to analyze the peel resistance in orderto adjust the manufacturing process. In this work, natural leather, thermoplastic rubber (TR) and a non-structural, solvent based, polyurethane adhesive were considered. The influence of the application of chemical and/or mechanical surface treatments on substrates in the peel strength of a T joint were analysed. To characterizethe surfaces, several test were considered, including Fourier Transform InfraredSpectroscopy (FTIR), Scanning Electron Microscope (SEM) and contact anglemeasurements. It was found that certain surface treatments are required to obtainan adhesive joint capable of satisfying the minimum strength requirements of theshoes sector.
