Abstract
A fibrous structure including a carded web of fibers that have higher individual-fiber linear density and which exhibit a spring characteristic. The web is sprayed with glass fibers or continuous glass filaments that randomly spread out flat on the web, and the web is subsequently needle-punched through a surface thereof to drive the glass fiber or glass filaments through the thickness of the web such that the glass fibers or glass filaments emerge through an opposite surface of the web.
