摘要: The present invention provides a lofty nonwoven web containing pneumatically drawn filaments, wherein the web has a density from about 0.01 g/cc to about 0.075 g/cc and the microfilaments have a weight-per-unit length between about 0.1 dtex and about 1.5 dtex. The invention also provides a process for producing the lofty nonwoven web.

摘要: Improved equipment and method for spinning filaments for nonwovens using an integral spinbank including one or more spinplates producing filament bundles separated by one or more central conduits for quench air. Embodiments include high velocity quench air driven into the central conduit or quench air blown or drawn in from outside the filaments into the central conduit. Means may also be provided for removal of undesired waxes and/or other condensates through a central exhaust removal using the central conduit. As quench air velocity is increased through the central conduit, the streams tend to improve total quench flow by deflecting opposing flows into a uniform stream. Other variations include division of quench air into flow zones that may be independently controlled and varying the angle of quench air flow and/or the spinplates to maintain separation distance between quench air and filament bundles.

摘要: A method of producing a fiber is provided where a liquefied polymer is divided into at least two streams. The streams are directed separately to a point of recombination, and extruded through, for example, a spinneret, and fiberized to form a single fiber having portions of each stream. The divided polymer streams are treated substantially identically from the point of division to the point of recombination.
