  • Stretch break method and product
    Patent number: 7559121
    Abstract: A method for stretch breaking fibers to produce a staple yarn and operating a staple fiber spinning machine that enables the production of a plurality of products of lot size smaller than a large denier tow product. The process includes at least two break zones and a consolidation zone downstream from a second break zone to form a staple yarn. The filaments are broken in a second break zone downstream from the first break zone by increasing the speed of the fiber fed into the process.
    Type: Grant
    Filed: January 5, 2005
    Date of Patent: July 14, 2009
    Assignee: E.I. du Pont de Nemours and Company

  • Stretch break method and product
    Publication number: 20040081825
    Abstract: A method for stretch breaking fibers to produce a staple yarn and operating a staple fiber spinning machine that enables the production of a plurality of products of lot size smaller than a large denier tow product. The process includes at least two break zones and a consolidation zone downstream from a second break zone to form a staple yarn. The filaments are broken in a second break zone downstream from the first break zone by increasing the speed of the fiber fed into the process. The yarn includes discontinuous and, optionally, continuous filaments.
