Title: **Francois Pinaud: Pioneering Innovations in Polyester Yarn Production**
Introduction
Francois Pinaud, an accomplished inventor based in Brignais, France, has made significant contributions to the field of polymer technology. With a focus on enhancing the production efficiency of polyester yarns, Pinaud holds two innovative patents that reflect his dedication to research and development in textile manufacturing.
Latest Patents
Francois Pinaud's recent patents are centered around the creation of undrawn pre-oriented PET yarns that improve production efficiency. His first notable patent, titled "Undrawn Pre-oriented Polyester Yarns with Improved Production Efficiency," describes a process involving the incorporation of 0.03 to 0.01% of fumed silica, with a particle size ranging from 5 to 15 nm. This innovative approach leads to a significant delay in crystallization, thus enhancing the overall performance of the yarns.
The second patent, named "Process for Obtaining PET Yarns with Improved Production Efficiency," outlines a process designed to elevate production efficiency during the spinning of undrawn, pre-oriented yarns. The process includes introducing 0.03 to 0.1% by weight of fumed silica into the molten PET, in the form of a dispersion within a masterbatch. The subsequent spinning, cooling, sizing, and winding operations are optimized to obtain a production gain of at least 7%, typically achieving a 10-15% increase when measured against filament shrinkage in dry air at elevated temperatures.
