Title: Callum Hill: Innovator in Cellulose-Based Fibers

Introduction

Callum Hill is a notable inventor based in Edinburgh, Lothian, GB. He has made significant contributions to the field of cellulose-based fibers, holding two patents that showcase his innovative methods. His work focuses on the manufacture and spinning of fibers that utilize cellulose nano-fibrils, which are derived from cellulose-rich materials such as wood.

Latest Patents

Callum Hill's latest patents include a process for the manufacture of cellulose-based fibers and a method for spinning fibers comprising cellulose nano-fibrils. The first patent details a method where the nano-fibrils are aligned along the main axis of the fiber from a lyotropic suspension. This alignment is achieved through the extension of the extruded fiber, which is dried under extension, allowing the nano-fibrils to aggregate into a continuous structure. The second patent further elaborates on this process, emphasizing the importance of a concentration of solids of at least 7% wt in the suspension, which is homogenized prior to extrusion. Both patents highlight the potential of cellulose fibers that contain at least 90% wt of crystallized cellulose.
