The “Incremental Draw Process” (“IDP”)“Incremental Draw Processing”* and “IDP”* are trademarks and designations for fiber orientation and elongation processes owned and patented by M. V. Sussman, Ph.D., P.E., and licensed through Arthur D. Little Enterprises, Acorn Park, Cambridge, MA 02140. is a newly commercialized technique that controls stress and temperature profiles during high speed drawing of synthetic polymer fibers. Fiber is drawn on a single pair of shaped rolls through a large number of small draw increments within a compact space. Draw zone length and residence time are increased substantially, allowing time for morphological change. Stress relaxation between draw increments and adjustment of temperature, tension, and rate of deformation (draw) at each draw increment more effectively control stress induced crystal growth and amorphous orientation. Ultra-orientation, improved tensile modules high tenacity, low break elongation, and low boil-off shrinkage have been produced. Because rates of plastic deformation during drawing are drastically reduced, high fiber throughput speeds are possible, allowing direct coupling to high speed spinning lines.Commercial applications include both textile and ultra-high strength industrial fiber production. Limited drawing of liquid crystal fibers has been demonstrated. © 1993 John Wiley & Sons, Inc.
