Latest Patents

Bennett's latest patents include advancements in hollow nylon filaments and yarns. One of his key inventions is a melt spinning process that involves extruding molten nylon polymer with specific characteristics. This process includes parameters such as a relative viscosity (RV) of at least about 50 and a melting point (T.sub.M) ranging from about 210°C to about 310°C. The method utilizes a spinneret capillary orifice with multiple segments to achieve a fractional extrusion void content defined by the ratio [EVA/EA] of about 0.6 to about 0.95. Additionally, the extent of melt attenuation is defined by the ratio [EVA/(dpf).sub.S], which ranges from about 0.05 to about 1.5. The process results in spun filaments that possess at least one longitudinal void and a controlled residual draw ratio (RDR).
