    Abstract: 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.

    Abstract: 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.

    Abstract: The present invention relates to an apparatus and a method as well as a system for extruding continuously molded bodies for producing filaments or staple fibers from an extrusion solution, such as a cellulose solution containing water, cellulose and tertiary amine oxide such as N-methylmorpholine N-oxide. In comparison with the methods known from the prior art, profitability can be increased in the production of continuously molded bodies (3) if the extrusion rate v is set to a value vnullBnullT0.33null10,000null(1/r2). In a system, profitability can be enhanced if the number r of rows is rnullnull(B/v)null10,000nullT0.33null1/2. T is here the fiber titer in T dtex, v the extrusion rate in m/min, r the number of the rows of extrusion duct orifices (12), and B an operational parameter which is not more than 4 and at least 0.5.

    Abstract: The invention relates to webs or batts comprising polytrimethylene terephthalate crimped staple fibers and fiberfill products comprising such webs and batts, as well as the processes of making the staple fibers, webs, batts and fiberfill products. According to the preferred process of making a web or batt comprising polytrimethylene terephthalate staple fibers, comprising polytrimethylene terephthalate is melt spun at a temperature of 245-285null C. into filaments. The filaments are quenched, drawn and mechanically crimped to a crimp level of 8-30 crimps per inch (3-12 crimps/cm). The crimped filaments are relaxed at a temperature of 50-130null C. and then cut into staple fibers having a length of about 0.2-6 inches (about 0.5-about 15 cm). A web is formed by garnetting or carding the staple fibers and is optionally cross-lapped to form a batt. A fiberfill product is prepared with the web or batt.
