摘要: Polymeric fibers along with methods and systems for extruding polymeric fibers are disclosed. The extrusion process preferably involves the delivery of a lubricant separately from a polymer melt stream to each orifice of an extrusion die such that the lubricant preferably encases the polymer melt stream as it passes through the die orifice.

摘要: Particulate-loaded polymer fibers along with methods and systems for extruding polymeric fibers are disclosed. The particulate-loaded polymer fibers have a fiber body that includes a polymeric binder with a plurality of particles distributed within the polymeric binder. Some of the particles are completely encapsulated within the polymeric binder and others may be embedded such that they are partially exposed on the outer surface of the fiber body. The polymers used in the fibers may be of high molecular weight and the encapsulated particles may be preferentially distributed towards the outer surfaces of the fibers.

摘要: Melt blown nonwoven webs are formed by supplying attenuating fluid to a meltblowing die through an attenuating fluid distribution passage whose distribution characteristics can be changed while the die and manifold are assembled. By adjusting the distribution characteristics of the passage, the mass flow rate of attenuating fluid to channels in the meltblowing die and the temperature of the attenuating fluid at the die outlets can be made more uniform.

摘要: Melt blown or spun bond nonwoven webs are formed by flowing fiber-forming material through a die cavity having a substantially uniform residence time and then through a plurality of orifices to form filaments, using air or other fluid to attenuate the filaments into fibers and collecting the attenuated fibers as a nonwoven web. Each die orifice receives a fiber-forming material stream having a similar thermal history. The physical or chemical properties of the nonwoven web fibers such as their average molecular weight and polydispersity can be made more uniform. Wide nonwoven webs can be formed by arranging a plurality of such die cavities in a side-by-side relationship. Thicker or multilayered nonwoven webs can be formed by arranging a plurality of such die cavities atop one another.

摘要: Melt blown nonwoven webs are formed by supplying fiber-forming material to a planetary gear metering pump having a plurality of outlets, flowing fiber-forming material from the pump outlets through a plurality of inlets in one or more die cavities, and meltblowing the fiber-forming material. Each die cavity inlet receives a fiber-forming material stream having a similar thermal history. The physical or chemical properties of the nonwoven web fibers such as their average molecular weight and polydispersity can be made more uniform. Wide nonwoven webs can be formed by arranging a plurality of such die cavities in a side-by-side relationship. Thicker or multilayered nonwoven webs can be formed by arranging a plurality of such die cavities atop one another.
