Abstract
A nonwoven composite has a first surface, a second surface, and a thickness extending between the first and second surfaces. The nonwoven composite comprises a plurality of natural fibers, a plurality of binder fibers, and a VOC-absorbing material. The binder fibers are bonded to or interlocked with the natural fibers. The VOC-absorbing material is dispersed within the nonwoven composite in such a manner that the density of the VOC-absorbing material in the nonwoven composite is greatest adjacent to the second surface of the nonwoven composite. A method for producing a nonwoven composite is also described.
