AbstractAn adsorbent textile product comprising a compressed nonwoven unitary batt of textile staple fibers, a cured binder disposed substantially throughout said batt, and an adsorbent material disposed substantially within the confines of said batt. In the disclosed product, the binder serves to hold the batt in its compressed condition such that the adsorbent is mechanically retained within the confines of the batt. In this way, the outer surfaces of said adsorbent material remain effectively free of the binder so that the adsorptive qualities of the adsorbent are preserved. An intermediate product and a process for making the disclosed products are also disclosed.
