Abstract
A three dimensional wipe pad with a superior capacity to remove contaminant solids particles from solid surfaces consists of a compressible bed of loose and discontinuous ultra-fine filaments which filaments include a significant number of sub-micron diameter microfilaments, enclosed and sealed in a pouch made from a deformable material which is permeable to the contaminant solids being removed. Rubbing a contaminated surface with the pad causes the contaminant solids to pass into the interior of the wipe where they are trapped in the interstices between the ultra-fine filaments. Liquids may be added to the pad to assist the passage of the contaminant solids particles into the interior of the pad.
Claims11
A three dimensional wipe pad for the removal of contaminants from solid surfaces which comprises a compressible bed of ultra-fine microfilaments, said microfilaments being loose and discontinuous and substantially unbonded and including a significant quantity of unbonded sub-micron diameter microfilaments, said bed being enclosed and contained in a sealed pouch made from a deformable sheet material which material is permeable to the contaminants being removed.
