Abstract
The invention is directed to a composite sheet suitable for use as artificial leather or a precursor to artificial leather, where both surfaces have a napped or brushed appearance. The composite sheet comprises a low-density, lightly bonded non-woven web that is stitch-bonded and bulked such that the stitch-bonding yarns are not visible to the naked eyes without the need of post-processing steps to hide the yarns. The composite sheet may have binder resin(s) dispersed therein and activated.
