Abstract:
Rotary spinning processes, more particularly processes for making hydroxyl polymer-containing fibers using a rotary spinning die, hydroxyl polymer-containing fibers made by the processes and webs made with the hydroxyl polymer-containing fibers are provided.
Abstract:
An improved method for creating fibers from a material dissolved in a solvent. In one embodiment, the method includes the steps of feeding a fiber making material dissolved in a solvent through a die including at least two rows of nozzles to form fiber strands. An attenuation medium is provided about the fiber strands. The attenuation medium is provided in a direction that is generally parallel to the fiber strands such that the attenuation medium elongates the fiber strands. The attenuation medium has a relative solvent-vapor content of at least about 50 percent.
