Title: James W. Tolliver: Innovations in Polyester Fiber Production

Introduction

James W. Tolliver is an inventor associated with Kinston, North Carolina, and E. I. du Pont de Nemours and Company. His work includes inventions related to producing fine-denier staple fibers and quenching melt-spun filaments. He is credited with 2 patents.

Latest Patents

Tolliver’s patent, “Preparing Fine Denier Staple Fibers,” describes a high-throughput process for producing fine-denier polyester fibers from low-molecular-weight polymer. The process is designed to improve fiber uniformity and mechanical properties.

His patent, “Apparatus for Quenching Melt Spun Filaments,” concerns an apparatus that radially quenches melt-spun filaments. A foraminous distribution cylinder separates the filaments from the gas supply chamber. Its porosity varies along the quenching chamber, increasing from a low value below the spinneret and then decreasing toward the chamber’s exit.

Career Highlights

Tolliver’s listed inventions address different stages of synthetic-fiber manufacturing: forming fine-denier staple fibers and controlling the quenching of melt-spun filaments. Both patents describe process or equipment innovations intended to support fiber production.

Collaborations

Tolliver’s listed coworkers include Harvey G. Anderson and James Victor Hartzog. The available information identifies them as coworkers but does not specify their roles in the patents.

Conclusion

James W. Tolliver’s two listed patents reflect his contributions to polyester fiber production, particularly in fine-denier fiber preparation and filament quenching.
