摘要：
A ply includes a fibrous nonwoven web fabric forming a foundational structure, wherein the foundational structure includes fibers forming first pores and is partially filled with particles, wherein the particles at least partially fill the first pores so as to form regions filled with particles, wherein the particles in the filled regions form second pores, and wherein an average diameter of the particles is greater than an average pore size of more than 50% of the second pores.
