Abstract
A fibrous structure including one or more nonwoven material layers comprising a fiber matrix, where the fiber matrix comprises polymeric binder fibers having a softening and/or melting temperature of about 190° C. or greater, where the article is adapted to withstand temperatures of about 190° C. or greater while in use; and where the article is a thermoacoustic insulation material.
Claims37
An thermoacoustic insulation material for a generator set comprising:
- a facing comprising a metallized polymeric infrared heat reflective film;
- a fibrous structure including one or more nonwoven material layers comprising a fiber matrix formed by distributing fibers via an air laying process or a carding and lapping process;
- wherein the fiber matrix comprises a thermoplastic binder having a melting temperature of about 180° C. or greater;
- wherein at least a portion of the thermoplastic binder has a length of about 70 mm or less;
- and
- wherein the fibrous structure has a density of about 200 kg/m3 or less.
