Title: The Innovative Mind of Lee W. Keene
Introduction
Lee W. Keene, an accomplished inventor based in Seaford, DE, has made significant contributions to the field of nylon yarn technology. With a total of three patents to his name, his work focuses on creating high-quality nylon flat yarns suitable for critical dye applications.
Latest Patents
One of Keene's latest patents revolves around the development of flat continuous multifilament nylon apparel yarns. This innovation is tailored for critical dye applications and encompasses a detailed process for manufacturing such yarns. The process involves spinning nylon polymer with a relative viscosity between about 35 and 80, followed by stabilization to create a feed yarn. A noteworthy aspect of this method is the sufficiently high withdrawal speed during spinning, which allows for the production of highly uniform feed yarns. The feed yarn undergoes drawing and subsequent relaxation, preferably arranged in a warp of yarns. This meticulous process results in drawn yarns exhibiting exceptional dye uniformity with large molecule acid dyes, making them ideally suited for use as flat yarns.
