Abstract: A melt blowing process comprising: (a) providing a thermoplastic polymer material that includes at least one or a plurality of polyester polymers and at least one or a combination of different meltable metal phosphinates; and (b) melt blowing the thermoplastic polymer material into at least one fiber or a plurality of fibers, with each fiber having a diameter or thickness that is less than about 10 microns. The metal phosphinate is in an amount that (a) reduces the viscosity of the polyester polymer and (b) functions as a crystallizing agent, which at least promotes crystallization of the polyester polymer, when the thermoplastic polymer material is melt blown into the at least one fiber. Non-woven and woven fibrous structures can be made using fibers made from this process.

Abstract: Provided are non-woven fibrous webs, methods and assemblies thereof. The non-woven fibrous web comprises a plurality of melt-blown fibers. The plurality of melt-blown fibers include a thermoplastic polymer blended with a phosphinate and/or polymeric phosphonate. The provided non-woven articles can afford a fine fiber diameter for enhanced acoustic insulation properties, dimensional stability, and superior flame-retardant properties when compared with conventional non-woven articles having similar fiber diameters.

Abstract: An assembly includes an enclosure including first and second regions spaced apart along a first direction, and a plurality of spaced apart acoustic baffles arranged along a second direction different from the first direction and disposed in the enclosure between the first and second regions. The plurality of spaced apart acoustic baffles includes adjacent first and second acoustic baffles. Each of the first and second acoustic baffles include an acoustically absorptive layer disposed on a sheet having a specific airflow resistance greater than 200 MKS Rayl. The first and second acoustic baffles define a channel therebetween. At least a portion of the channel extends along a longitudinal direction making an oblique angle with the first direction.

Abstract: 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%.

Abstract: Dimensionally-stable fibrous structures including ceramic-coated melt-blown nonwoven fibers made of a flame-retarding polymer and processes for producing such fire-resistant nonwoven fibrous structures. The melt-blown fibers include poly(phenylene sulfide) in an amount sufficient for the nonwoven fibrous structures to pass one or more fire-resistance test, e.g. UL 94 V0, FAR 25.853 (a), FAR 25.856 (a), and CA Title 19, without any halogenated flame-retardant additive, and have a ceramic coating. The melt-blown fibers are subjected to a controlled in-flight heat treatment at a temperature below a melting temperature of the poly(phenylene sulfide) immediately upon exiting from at least one orifice of a melt-blowing die, in order to impart dimensional stability to the fibers. The nonwoven fibrous structures including the in-flight heat-treated melt-blown fibers exhibit a Shrinkage less than a Shrinkage measured on a nonwoven fibrous structure including only fibers not subjected to the controlled in-flight heat treatment operation, generally less than 15%.
