Method for preparing compact spun slub high count yarns

The invention provides a method for preparing compact spun slub high count yarns and the compact spun slub high count yarns prepared thereby. A low count yarn gap sheet control and high count primary drawing matched mode is adopted in a spinning process in a method for preparing blended far infrared fibers; and pressure of 10 to 14kg is applied to a drawing zone of a spinning frame, a chemical fiber leather roller is used, Vickers hardness is 70 to 83 degrees, and special long stapled cotton in a certain ratio is selected as a raw material. The method overcomes the defect that the conventional high count slub yarns have low strength and a large number of long hairs, the wearability of a product is improved through technological innovation, the slub yarns are united in a compact bundling device to make a fabric surface have smooth and clear appearance, and the third dimension of a fabric is increased.
