Title: The Innovations of Malcolm O. Darby

Introduction

Malcolm O. Darby is a notable inventor based in Columbia, SC (US). He has made significant contributions to the field of materials science, particularly in the production of specialized yarns. His innovative approach has led to the development of a unique process that enhances the performance of poly(.epsilon.-caproamide) yarn.

Latest Patents

Malcolm O. Darby holds a patent for a process titled "Highly oriented, partially drawn, untwisted, compact." This patent describes a method for producing a highly oriented, partially drawn, untwisted, compact poly(.epsilon.-caproamide) yarn at windup speeds ranging from 3500 to 6000 meters per minute. The process involves overfeeding the yarn to entangling means and overfeeding the shrinking yarn to the winder. Notably, the yarn is 'drawn' in the quench stack, and draw-twisting is omitted, allowing the produced yarn to perform comparably to conventional, draw-twisted yarn in applications such as knitting and weaving.
