A material processing apparatus is disclosed. This material processing apparatus is particularly developed to utilize a quasi-traveling microwave to conduct heat treatment for a thread-type article like fiber, silk, artificial fiber, and artificial silk. The material processing apparatus comprises a primary waveguide tube, a microwave blocking plate, a secondary waveguide tube, and at least one microwave absorbing member disposed of in the primary waveguide tube. By such design, a microwave source supplies a microwave to the secondary waveguide tube and the primary waveguide tube, such that the microwave travels in the two waveguide tubes so as to become a quasi-traveling microwave. Therefore, in the case of a thread-type article being be fed into the primary waveguide tube via the secondary waveguide tube by a thread-type article transferring mechanism, the thread-type article is steadily and evenly heated by the quasi-traveling microwave in the two waveguide tubes.
