  • High bulky wool spun yarn and a drafting apparatus for preparing the yarn
    Patent number: 5553357
    Abstract: A high bulky wool spun yarn for knitting or weaving, which has high bulky properties formed by bulky loops in the bundle of the yarn, and a drafting system for making the same is provided. The drafting system includes a spinning machine with an improved front top roller that periodically changes the contacting points of a wool roving to form uniform bulky loops in a bundle of a wool spun yarn, thereby forming the high bulky wool spun yarn. Multiple grooves which are perpendicular to the axis of the top roller are formed on the surface of the top roller. Additionally, multiple slanting grooves which are slanted at about 45.degree. to the axis of the top roller or to the multiple grooves are formed on the surface of the top roller. Abrasion resistant fillers are inserted and fixed in the multiple slanting grooves.
