New fibers are among the many products of technology that have significantly impacted on society in the years since World War II. Nylon, rayon, orlon, dacron, polyester, and a host of other fibers have become household words because of their widespread use, primarily in textiles of all sorts.
Fibers made of glass have found wide application for home insulation and as a key component of fiberglass construction materials used in the manufacture of boats and numerous other valuable products. More recently, glass fiber is helping to transform communications as fiber-optic cables are rapidly replacing metal wires as carriers of phone messages around the world.
Now another generation of fibers is under development, whose impact may well be as great. At the University of Wisconsin-Madison, chemical engineering professor James A. Koutsky and faculty associate Stanley A. Dunn are experimenting with an approach to making stiff, high-quality fibers at a much lower unit cost than can be attained by current methods. They expect the new technique will draw upon a range of materials previously regarded as impractical for fiber-making. They also expect it to yield a variety of products, including lighter, smaller lead batteries for cars; new fiberglass composites whose superior stiffness and low cost make them the natural choice for making about bodies; fluoride optical fibers that carry crisper messages via pulses of light; and, perhaps, exotic new fibers that would make the manufacture of high-temperature superconducting wires a possibility.
Koutsky and Dunn have revived and refined a dormant technology, Inviscid Melt Spinning (IMS), that engineers
