Title: Heping Zhang: Innovator in Poly(ethylene terephthalate) Technologies
Introduction
Heping Zhang is a notable inventor based in Summerville, SC (US). He has made significant contributions to the field of materials science, particularly in the development of advanced poly(ethylene terephthalate) (PET) technologies. With a total of 5 patents to his name, Zhang's work has had a considerable impact on industrial applications.
Latest Patents
Zhang's latest patents include innovations in PET yarns with improved loop tensile properties. His work on poly(ethylene terephthalate) monofilaments focuses on enhancing loop strength and toughness, as well as improving tensile strength and tensile toughness. The yarns he developed can achieve a loop toughness of at least 2 gf/den, a loop tenacity of at least 7 gf/den, a tensile toughness of at least 0.9 gf/den, and a tensile tenacity of at least 4 gf/den, with a DSC crystallinity of at least 35%. Additionally, he has patented a process for producing these monofilaments, which includes melt extrusion, orientation by stretching, and heat treatment. His innovations are particularly beneficial for industrial fabrics, especially those used in paper machine clothing, as they provide load-bearing capabilities that resist loop failure and fabric creep under high temperatures and loads. Another significant patent involves a low tensile creep belt, which is an endless fabric belt designed to withstand substantial running tension, formed from ultra-high molecular weight polymer strands that exhibit near-zero creep at high tensile loads.
