Title: The Innovations of Daniel Scott Colley

Introduction

Daniel Scott Colley is an accomplished inventor based in Alexandria, VA. He is known for his significant contributions to the field of polymer processing, particularly through his innovative patent related to the flash-spinning process. His work has implications for the production of advanced materials used in various applications.

Latest Patents

Colley's most notable patent is the flash-spinning process, which involves an improved apparatus and method for creating plexifilamentary film-fibrils. This invention incorporates a static mixing device within the conduit that delivers polymer and spin agent to the spin orifice of the apparatus. The design includes a chamber located immediately upstream of the spinning orifice, enhancing the mixing process. The resulting plexifilamentary webs exhibit more densely spaced film-fibrils, increased tie points, and fewer holes. Consequently, bonded plexifilamentary sheets produced from these webs demonstrate a more uniform thickness and slightly higher tensile strength compared to those made without static mixers. Colley holds 1 patent for this innovative process.
