摘要： Disclosed is a process for preparing crimpable bicomponent fibers from two poly(trimethylene terephthalate) starting materials that differ from one another in intrinsic viscosity. One starting material is characterized by an intrinsic viscosity ≦0.7 dL/g. The relatively low intrinsic viscosity allows the employment of a low melt temperature, with concomitant reduction in the evolution of acrolein, and without significant degradation in the properties or processibility of the bicomponent fiber.

摘要： An electrohydrodynamic spraying or spinning deposition system, which includes a common source of pressurized liquid within a manifold, and an array of 2 or more spraying tips, each tip being fed from the common source of pressurized liquid to create a liquid flow path. An individual flow impedance device is disposed within each tip's individual liquid flow path from the pressurized liquid source into each spraying tip. The individual flow impedance devices are disposed within a replaceable sheet, which can be easily cleaned or changed to accommodate the instance liquid viscosity and composition. A high voltage source is applied to create a high voltage potential applied between the tip array and a deposition surface.

摘要： A method and apparatus for spinning filaments of a polymeric material includes a first temperature control arrangement for heating a spin pack to a first predetermined reference temperature greater than the predetermined polymer inlet temperature such that the temperature across a polymer filter holder and the spinneret plate in the spin pack is substantially uniform, whereby the temperature of the filaments emanating from the spinneret plate is substantially uniform. A plate assembly having at least one polymer flow passage therein is disposed between the outlet of the pump and the inlet of the spin pack. A second temperature control arrangement for independently controlling the temperature of the plate assembly to a second predetermined reference temperature is provided. The second predetermined reference temperature is selectable to a temperature above, equal to, or below the predetermined polymer inlet temperature, whereby the temperature of polymer conveyed through the polymer flow passage in the plate assembly is selectably controllable to a predetermined polymer temperature lying within a predetermined range of the second predetermined reference temperature.
