Title: Michel Verdan: Innovator in Composite Elastic Yarns
Introduction
Michel Verdan is a notable inventor based in Geneva, Switzerland. He has made significant contributions to the field of textile engineering, particularly in the production of composite elastic yarns. With a total of 2 patents, Verdan's work has paved the way for advancements in fabric technology.
Latest Patents
One of Verdan's latest patents is the air-jet method for producing composite elastic yarns. This innovative continuous method allows for the production of composite elastic yarns at speeds up to 700 m/min. The process involves stretching an elastomeric yarn, such as spandex, by 2.0× (100%) to 10.5× (950%) while heating it to a maximum temperature of 220°C. This is done in a single or double stage draft. Following this, air-jet entangling with a relatively inelastic yarn component creates the composite elastic yarn. The final step includes in-line heat-treating the yarn at a maximum temperature of 240°C. The resulting composite elastic yarn boasts improved stitch clarity, making it particularly suitable for hosiery. Its properties can be tailored to provide fabric characteristics for knit and woven fabrics that were previously unattainable with standard spandex yarns.
