The beginning of the new millennium is sure to bring about many drastic changes in the life of mankind. One of them is going to be the shift towards natural dyes and their efficient usage compared to their synthetic counterpart which has been slowly losing, mainly due to international awareness to environment and ecology preservation. The natural dyes which are non-pollutant appear as an ideal choice as they are non-toxic and their handling is easy. The saving of time and energy is obviously of interest to the textile industry, microwave as new technique allows the usage of less energy in...

The use of microwave energy for processing materials has the potential to offer many advantages in reduced processing times and energy savings. In conventional thermal processing, energy is transferred to the material through convection, conduction, and radiation of heat from the surfaces of the material. In contrast, microwave energy is delivered directly to materials through molecular interaction with the electromagnetic field. In heat transfer, energy is transferred due to thermal gradients, but microwave heating is the transfer of electromagnetic energy to thermal energy and is energy...
