Investigation of the process of shrink and volume of combined wool-and-chemical fiber under effects of electromagnetic waves of super high frequency

As a research object, a combined air jet yarn with the use of a complex chemical high-shrinkage yarn subjected to the action of electromagnetic waves of the microwave range was produced.The goal is to study the shrinkage process and increase the volume of the combined filament using electromagnetic waves of the microwave range.As a result of experimental studies, the obtained data show that the use of electromagnetic waves in the microwave range can achieve a significant increase in the volume of yarn, not inferior to the traditional methods of heat and moisture treatment of textile materials.
