Latest Patents
One of Dean H Smiley's latest patents is titled "Process of drawing yarn using an oscillating draw assist element." This invention describes a process and apparatus for drawing polyamide yarn, where the yarn, having a lubricating finish, is drawn while being spirally advanced in frictional contact with the outer surface of a yarn draw assist element. The outer surface of the draw assist element moves at a speed at least 100 times slower than the speed at which the yarn is advanced. This innovative process prevents the build-up of deposits on the heated rolls used in yarn production.
Another significant patent by Smiley is for an "Antistatic filament having a polymeric sheath and a conductive polymeric core." This filament features a polymeric sheath and a conductive polymeric core that constitutes less than 10% of the cross-sectional area of the filament. This invention addresses the need for antistatic properties in yarns, enhancing their usability in various applications.
