<p>The present invention relates to a high bulky wool spun yarn for knitting or weaving, which has a high bulky property by forming bulky loops in the bundle of the yarn. In a drafting system of a spinning machine, the present invention relates to an improved front top roller (32) of the drafting system, which periodically changes the contacting points of a wool roving so as to form uniform bulky loops in the bundle of a wool spun yarn. In the front top roller (32), multiple grooves (39) which ware perpendicular to the axis of the top roller (32) are formed on the surface of the top roller (32), multiple slanting grooves (37) which are slanted at about 45 DEG to the axis of the top roller (32) or to the multiple grooves (39), are formed on the surface of the top roller (32), and abrasion resistant fillers (38) are inserted and fixed in the multiple slanting grooves (37). The high bulky wool spun yarn of this invention is prepared by using the front top roller (32) in the drafting system of a spinning machine. <IMAGE></p> |
