Abstract
The present process involves applying a plasticizer- or solvent-containing solution to a subject fabric, preferably under heated conditions, and then mechanically abrading the treated fabric. The process results in the rearrangement of the fabric structure, as a plurality of branched fibrils are created along the length of the yarn filaments. Thus, the molecular weight of the fabric's yarns and, therefore, the strength of the polymer chains are maintained. Fabrics made from this process, which exhibit a silk-like hand that results from the presence of multiple integral fibrils and branched fibrils, are also provided.
