Abstract
A composite nonwoven fabric is constructed to have high breathability, a low modulus and a good hand. The composite is comprised of a fibrous nonwoven material attached to a highly elastic breathable foam film substrate. The foam film substrate is dimensioned to be thin enough to provide numerous apertures and/or voids therethrough. The attachment of the fibrous nonwoven material to the foam film substrate is accomplished by needlepunching portions of at least some strands of the nonwoven material through the apertures in the elastic foam film. During the needlepunching process, the numerous apertures and/or voids in the foam film facilitate the passage of strands of the nonwoven material through the foam film by the needles while minimizing damage to the structure of the foam film by the needles. Alternatively, the composite nonwoven textile is constructed by attaching fibers to the breathable elastic foam film by flocking. The fibers may be attached by an adhesive or may be attached by application to the elastic foam film while the film is still 'wet' (i.e. before the film is cured).
