ABSTRACT:
The composite sheet of this invention provides a fabric of superfine fibers impregnated with a high molecular weight elastic polymer and a hardened high molecular weight organic compound, having a nap on its surface formed from the ends of the fibers which constitute the fabric. The root portion of at least a part of the nap is bonded into a bundle by the high molecular weight organic compound, and the tip portion of the nap constituting the bundle is fibrous, thereby including at least some individually distinct fibers.
The composite sheet or fabric has the appearance of a high-quality napped woolen woven fabric, deep in color, having a smooth touch, having bulkiness, water-washability and easy care due to excellent crease resistance and packability. It is especially suitable for clothing.
