ABSTRACT:
A reusable pad for the absorption, dispersion and retention of a liquid comprises an interior layer of hydrophobic material for receiving the liquid, a median layer consisting of a non-woven web of carded and cross-laid viscose rayon fibres and an outer layer of substantially waterproof polyurethane film. The fibres of the median layer have a cross-section of substantially rigid multilimbed configuration. The web is stitchbonded to form a cohesive layer for dispersing and absorbing the liquid. The web is stitchbonded with a thread under medium tension whereby uniform absorption characteristics are retained throughout said web. The interior layer, median layer and outer layer are joined to form a pad of unitary construction and capable of being washed for reuse.
