ABSTRACT A composite sheet comprising a fiber base and an 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.
