Title: Chengqian Zhu and Polyester Fiber Innovation.
Introduction
Chengqian Zhu is an inventor based in Suzhou, China, associated with Jiangsu Hengli Chemical Fibre Co., Ltd. His patent work addresses the production of profiled polyester fibers with a low broken-filament, or lousiness, rate.
Latest Patents
Zhu is named on one patent, “Method for Producing Profiled Fibers Having Low Broken Filament Rate by Polyester FDY Process.” The method adjusts the horizontal and vertical positions of ceramic yarn guides on a pre-entangling guide frame. This helps keep the filament bundle vertically aligned in the pre-entangling device and supports an effective jitter effect during production.
The patent describes lousiness-rate ranges of 0.35–0.65% for triangular profiled fibers, 0.85–1.25% for trilobal profiled fibers, and 0.5–0.85% for flat profiled fibers. Zhu’s listed patent portfolio comprises 1 patent.
Career Highlights
Zhu’s documented invention focuses on improving filament handling in the polyester fully drawn yarn (FDY) process. By refining yarn-guide positioning, the method aims to reduce broken filaments and produce profiled fibers with controlled lousiness rates.
Collaborations
Zhu is associated with Jiangsu Hengli Chemical Fibre Co., Ltd. His listed coworkers include Yu Li and Shouzuo Liu.
Conclusion
Chengqian Zhu’s patent presents a process adjustment for producing profiled polyester fibers with reduced lousiness, highlighting his contribution to fiber-manufacturing innovation.
