Title: Ann S Johnson: Innovator in Synthetic Fiber Technology
Introduction
Ann S Johnson is a prominent inventor based in Central, SC (US). She has made significant contributions to the field of synthetic fiber technology, holding 2 patents that showcase her innovative spirit and technical expertise.
Latest Patents
Her latest patents include "Processes and systems for making synthetic bulked continuous filament yarns." This invention provides processes and apparatus that allow for the variable control of the morphology of bulked continuous filament (BCF) yarns. Specifically, the BCF yarn is melt-spun, drawn, and textured in a one-step spin-draw-texture (SDT) process. Prior to texturing, the yarn is subjected to a differential temperature condition, which is achieved using duo rolls during the drawing process. One of the rolls is maintained at a higher temperature than the other, enhancing the quality of the yarn produced.
Another notable patent is a "Laboratory device to assist in the simulation of synthetic fiber." This laboratory-scale device features a pair of laterally spaced-apart flexible heat-resistant cords, which are tensioned between rigid cross-support bars. The device allows for the manual or automated lateral winding of synthetic heat-settable fibers or yarns, enabling researchers to investigate various effects on heat-setting conditions.
