Title: Michael M McNamara: Innovator in Nylon 66 Yarn Technology
Introduction
Michael M McNamara is a notable inventor based in Gaffney, SC (US). He has made significant contributions to the field of textile engineering, particularly in the development of nylon 66 yarn. With a total of 3 patents to his name, McNamara's work has advanced the properties and applications of nylon materials.
Latest Patents
One of McNamara's latest patents is a process for nylon 66 yarn that possesses a soft hand. This innovative yarn exhibits particular stress-strain properties, typically resulting in a soft, luxuriant hand in fabric form. Compared to conventional nylon 66 with similar boiling water shrinkage, this novel yarn demonstrates a higher modulus at break, a lower modulus at 10% elongation, a positive stress index, and excellent denier uniformity. The process involves applying tension to the yarn shortly after the solidification of the filaments and heating it to specific temperatures to minimize yarn retraction.
Another significant patent is related to the nylon 66 spinning process. In this process, polyamide yarn is melt spun at high speed and drawn almost immediately after solidification. A turbine-driven feed roll replaces the conventional feed and separator roll, resulting in unusually low drawing tension and exceptionally uniform yarn.
