Process for producing a nonwoven wadding, characterized in that it comprises the steps of forming a continuous band of continuous filaments of decomposed curls, laterally extending a bundle of filaments of decomposed curls and forming a first fibrous layer; depositing a second layer of non-woven fibrous material in contact with the first layer, and needle-puncturing the fibers by subjecting them to a series of rapidly reciprocating needles whereby the fibrous layers are intimately entangled.
