A multi-layer material for use in incontinence products comprises a base layer comprising a needled felt containing not less than 50% by weight polyester fiber, wherein the surface regions of the felt are denser than the central region thereof, which remains substantially unneedled. In addition, a second, multi-ply, layer is provided by a unitary fabric comprising two outer plies of knitted polyester fiber fabric with a ply of monofilament polyester accommodated therebetween. In order to prevent strike-through, furthermore, a barrier layer, e.g. of a polyurethane coated fabric, is also provided, as is also a fourth, skin-contact, layer with a nap finish to provide a comfortable "feel" to the product. Incontinence products made from this material exhibit good absorbency, little or no strike-through and a dry skin effect.
A material for use in multi-layered incontinence products including a non-woven absorbent layer characterised in that the non-woven layer includes a first, base, layer comprising a needled felt containing not less than 50% by weight polyester fibre, wherein surface regions of the felt are denser than a central region thereof, which remains substantially unneedled, and the material includes a second, multi-ply, layer comprising two outer plies of polyester fabric between which is accommodated a ply of monofilament polyester, wherein the layers are joined together and the second layer serves to spread fluid applied to the product and thus enhance absorption thereof into the first layer and also to provide a barrier for the prevention of wet-back.
An incontinence product of a multi-layered construction comprising a first, base, layer comprising a needled felt, a second layer serving to spread fluid applied to the product and thus enhance absorption thereof into the first layer and also to provide a barrier for the prevention of wet-back,
