Patent number: 11702767Abstract: The present invention is a novel gas assisted nozzle and a method for micro and nanofiber production. In this composite nozzle, a high velocity gas stream is introduced through a core protruding orifice, while a liquid is introduced via at least one satellite orifice, external to the core orifice. The liquid flow is picked-up and accelerated (blown) by the gas stream from the tip of the protruding gas nozzle. This avoids passing the high velocity gas over the surface of the slow flowing liquid and achieves the acceleration of the liquid flow on its approach to being picked-up by the gas stream. Proper control of the gas and the polymer liquid flow results in fine liquid blowing and formation of micro and nanofibers.Type: GrantFiled: May 11, 2018Date of Patent: July 18, 2023Inventors: John Rawlins, Jin Hee Kang

Publication number: 20150141567Abstract: This invention relates to an alloy comprising polyurethane and polyolefin. It has now surprisingly been found that a specific composition of polyolefin and polyurethane has surprising mechanical properties and at the same time has transparent characteristics and/or appearance. The present invention provides an alloy with remarkable mechanical properties. The phases do not macro-phase separate. Thus, this stable and potentially broad interface is very effective in stress transfer when the alloy is strained. As one might expect, the hardness values for the alloys are in between the hardness values of each component but the other physical properties are no adjusted. In this way, when considering the hardness and mechanical values, these alloys behave like two compatible polymers.Type: ApplicationFiled: May 17, 2013Publication date: May 21, 2015Inventors: Carsten Hoej, Niels Joergen Madsen, Umit G.
