Production device and production method for magnetic fiber blended conformal yarns, and magnetic fiber blended conformal yarns

Abstract

Disclosed are a production device and a production method for magnetic fiber blended conformal yarns. Fed roving includes at least two types of fiber blended roving, including magnetic fibers. By adding left and right magnets on the outer circumference of a middle roller, the magnetic fibers in first strands obtained by untwisting and drawing the roving in a rear drawing zone are dispersed within a certain width range; by adding an adsorption roller that rotates synchronously with a front rubber roller to the front part thereof, and adding an adsorption magnet to the outer circumference of a certain width of an adsorption roller, the magnetic fibers in second strands obtained by drawing the first strands in a front drawing zone are adsorbed upward, the fibers except the magnetic fibers in the second strands are strongly twisted close to the lower part of the front roller and located at the cores of final yarns, and the magnetic fibers are weakly twisted close to the upper part of the adsorption roller and located at the outer parts of the final yarns, thereby forming overall yarn structures that are tight inside but loose outside.
