A composite sheet comprising a fiber base and a binder, wherein said binder is broken into small fragments which adhere to the fibers, but at least some not to each other. Said composite sheet is produced by a method comprising the step of (a) applying a binder to a fiber base and (b) directing a fluid jet stream to the fiber base during or after coagulation of the binder applied thereto. The composite sheet of this invention is very soft and has considerable strength, because the fluid jet breaks weak portions of the binder only to divide the binder into small fragments, without breaking the tougher portions of the binder which mainly contribute to the strength of the leather.

Composite sheet and method of producing same

Woven or knitted fabrics of soft touch and elegant appearance composed of yarns including bundles of superfine fibers of less than 0.7 denier which are at least partly bound with a cured silicone polymer.

Composite woven or knitted fabric

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.
