    • Abstract


      In this study, the adhesion strength of melamine–formaldehyde (MF) resin-based adhesives is improved manifolds by incorporating a little amount of starch in it for adhering Denim cloth. The effect of varying starch content inthe adhesive has also been studied. The reaction conditions of the adhesive preparation with respect to time, temperature and pH have been optimized. To understand the right storage condition, the denim fabric after application of adhesives isstored at different conditions of humidity and temperature. Thermogravimetric analysis (TGA) and Fourier transform infrared (FTIR) have been performed to study the effect of starch on the thermal stability and to study the interactions between the chemical species of the adhesive, respectively. Scanning electron microscopy (SEM) was done to study themorphology of the adhesive. At elevated temperature, the adhesion strength was found to improve and there was no effectof high humidity (90% RH) on the adhesion strength. The effect of temperature on viscosity changes of the adhesives was also recorded. Further, the chemical resistance of the adhesive in various solvents having different pH and polarity are also studied.
