Title: Innovations of James M. Turner in Polyester Yarn Technology

Introduction

James M. Turner is a notable inventor based in Cary, NC (US), recognized for his contributions to the field of polyester yarn technology. With a total of 10 patents to his name, Turner has made significant advancements that enhance the performance and stability of polyester fibers used in various applications.

Latest Patents

One of Turner's latest patents focuses on a dimensionally stable polyester yarn designed for high tenacity treated cords. This innovation involves a spun polyester fiber and a drawn polyester yarn, along with methods for their production. The process begins with extruding a molten melt-spinnable polyethylene terephthalate, which has an intrinsic viscosity of at least about 0.8, through a shaped extrusion orifice. This forms a molten spun yarn that is gradually solidified in a controlled environment. The yarn is then withdrawn at a sufficient speed to create a crystalline partially oriented yarn, which is subsequently hot drawn to achieve a drawn yarn with a specific crosslink density. The resulting yarns and fibers are particularly suited for manufacturing treated tire cords that exhibit high tenacity and improved dimensional stability.
