摘要： The invention relates to a continuous dry spinning process for preparing a fiber from a polymer solution having concentrations of polymer, salt, solvent and water. After the fiber is extruded and quenched, the fiber is placed in contact with a conditioning solution comprising concentrations of solvent, salt, and water. The conditioning solution acts upon the fiber to plasticize the fiber prior to being drawn. The conditioning solution has concentrations of solvent, salt, and water so that the fiber is plasticized to the extent necessary for drawing but does not plasticize the fiber to such an extent as to re-dissolve the fiber into a polymeric solution. A heat-treated fiber manufactured from this process has improved shrinkage and can be colored to darker shades.

摘要： This invention relates to a method and apparatus for sweeping dust and debris from the needles of a wand which is for applying an electrostatic charge to a plexifilamentary film-fibril web. The needles of the wand tend to acquire dust and debris from the polymer and by the present invention the dust and debris are efficiently swept away by a gaseous fluid flow over the needles preferably so that the fluid passes circumferentially over the needles through an annular passage.

摘要： The invention relates to nonwoven fabrics containing polymeric multiple component fibers which include a core component and a plurality of wing components attached to the core. The polymeric core component has an elasticity that is greater than the elasticity of at least one of the wing polymeric components. The fibers assume a spiral twist configuration in which the plurality of wings substantially spiral about the core. In a preferred embodiment, the nonwoven fabrics have elastic stretch and recovery properties with a textile-like hand.
