Effect of Processing Factors on the Bonding Strength of Fibrous Assembles by Dielectric Heating

Article Preview

Abstract:

In the dielectric heating by using microwave, both the interior and exterior of fiber materials can be evenly heated simultaneously. Especially, in case of heating the material of low thermal conduction by normal furnaces, thermal loss is great and it takes long time to finish the required treatment. However, if microwave is applied to fibrous materials, it can be treated rapidly. Also, application of microwave system has the results of remarkably enhancing productivity and improving working environment owing to no air pollution. Thus, in this study, the bonded polypropylene (PP) fibers and PP/PET nonwovens have prepared by dielectric heating with various organic solvents, and their morphological structures and debonding force have investigated with different treatment time.
