Facing for Acoustic Batts that Contain Melt-Film Fibrillation

Melt-Film Fibrillation (MFF) technology produces a facing for acoustic batts for vehicle sound insulation that offers equivalent or superior sound-deadening performance at reduced weight and cost. Equivalent weights of MFF fibers produce substantially enhanced sound insulation over conventional batts incorporating melt-blown, polypropylene fibers. The submicron fibers of MFF increase sound impedance, with significant performance improvements realized in the frequencies between 3000 Hz and 5000 Hz.

The extreme thinness and high aspect ratio of submicron fibers translates to higher surface area per given weight of fiber than can be achieved with larger fibers like those produced through traditional melt-blowing. In general, it is anticipated that fine fiber-containing materials may achieve equivalent product performance with less fiber mass, significantly reducing material cost, weight, size, shipping costs, and so forth; or using equivalent fiber mass, performance in many applications could be significantly enhanced.
