Abstract

A method for preparing full-dull cotton-like polyester fibers includes: sequentially passing a full-dull polyester POY fiber and a full-dull polyester FDY fiber through a first yarn guide, a yarn guide tube, a second yarn guide, a first yarn feeding roller, pre-entangling, a second yarn feeding roller, a first deformation hot box, a cooling plate, a false twister, a third yarn feeding roller, a middle entangling device, a setting hot box, a setting yarn feeding roller, oiling, and DTY winding and forming to obtain the same. The first and second yarn guides are both yarn guide wheels; a tow is wound around the first yarn feeding roller for 2-3 turns; an inferior angle of the tow before and after contacting a groove bottom of the second yarn guide is 140°-160°; a linear velocity ratio of the first yarn feeding roller to the second yarn feeding roller is 1.05-1.06.
