The results of experimental researches of the influence of microwave exposure while dyeing wool on the degree of fixation of active dyes and tenacity of the yarn after dyeing are presented. The intensifying effect of electromagnetic waves on the microwave dyeing of wool fibers by periodic process was defined.

The aim of the research was the study of technology of wool fibers dyeing by the MICROWAVE waves. The comparative analysis of the results of dyeing by the classical technology and with the influence of MICROWAVE exposure was carried out. Classical technology allows achieving a high degree of dye fixation on the fiber, but the full technological cycle has a high duration. Using waves with super-high frequency with the power of 600 watts for 4—5 minutes while colouring wool fiber allows achieving a high degree of fixation of dye on the fiber while reducing the overall length of the process.

Influence of electromagnetic waves of ultrahigh-frequency range on results of wool fiber dyeing
