Abstract:
A reusable and absorptive mat for the absorption, dispersion and retention of a liquid is disclosed. The absorptive mat comprises a plurality of non-woven layers, of carded and randomly laid viscose rayon fibres having a cross-section of substantially rigid multi-limbed configuration. The layers are stitchbonded in an as laid state, thereby substantially limiting entanglement and breaking of individual fibres. The stitchbonding is performed with a thread under limited tension so as to maintain uniformity of the absorptive mat. Also disclosed is a method of manufacturing a reusable and washable article for the absorption, dispersion and retention of a liquid comprising providing a plurality of viscose rayon fibres, carding the plurality of fibres, randomly laying the carded fibres into a continuous random web structure and stitchbonding the continuous random web structure in an as laid state.
