  • Patent number: 6546711
    Abstract: A sewing yarn comprises at least two roving yarns, which are twisted together with one another, whereby each roving yarn has the structure of a core yarn, comprising at least one first multifilament yarn component, forming a yarn core, and a second fiber yarn component spun over the core. In the cross-section of the sewing yarn, the fiber yarn thread covering of at least one roving yarn contains less than 41 individual fibers. For the manufacture of each roving yarn, a slubbing made of fiber yarns is compacted to 10 to 25 times of the volume of the roving yarns, introduced into a spinning device with the multifilament yarn component serving as the core, and is spun in said device, with at least two roving yarns being thereafter twisted together with one another.
