    摘要： A process and apparatus for producing a dimensionally stable melt blown nonwoven fibrous web. The process includes forming a multiplicity of melt blown fibers by passing a molten stream including molecules of at least one thermoplastic semi-crystalline (co)polymer through at least one orifice of a melt-blowing die, subjecting at least a portion of the melt blown fibers to a controlled in-flight heat treatment operation at a temperature below a melting temperature of the at least one thermoplastic semi-crystalline (co)polymer immediately upon exiting from the at least one orifice, and collecting at least some of the melt blown fibers subjected to the controlled in-flight heat treatment operation on a collector to form a non-woven fibrous structure. The nonwoven fibrous structure exhibits a Shrinkage less than a Shrinkage measured on an identically-prepared structure including only fibers not subjected to the controlled in-flight heat treatment operation, and generally less than 15%.

    摘要： A nozzle, die, apparatus, system and method for forming a fiber population having a median diameter less than one micrometer, and nonwoven fibrous webs including a population of such sub-micrometer fibers. The nozzle includes a first conduit having a first terminal end, a second conduit positioned coaxially around the first conduit and having a second terminal end proximate the first terminal end, wherein the first and second conduit form an annular channel between the first and second conduit, and additionally wherein the first terminal end extends axially outwardly beyond the second terminal end. The die includes at least one such nozzle, and the apparatus and system include at least one such die. Methods of making nonwoven fibrous webs including a population of sub-micrometer fibers, and articles including such nonwoven fibrous webs, are also disclosed.
