Hydroembedded film-based composites
A substrate has an elastomeric film having surfaces and a nonwoven web having fibers, wherein a plurality of fibers is partially embedded in one surface of the film. In addition, a substrate has an elastomeric film and a nonwoven web having fibers, wherein a plurality of fibers is partially embedded in one surface of the film, and wherein the substrate is essentially free of adhesives and film-based microfibers. A method for making a film/nonwoven composite includes providing an elastomeric film traveling in a machine direction; providing a nonwoven web traveling in the machine direction in face-to-face contact with the film, wherein the nonwoven web includes fibers; and impinging the elastomeric film with hydro jets such that at least some of the fibers become embedded in the film.
1. A method for making a film/nonwoven composite, the method comprising:
providing an elastomeric film traveling in a machine direction;
providing a nonwoven web traveling in the machine direction in face-to-face contact with the film, wherein the nonwoven web includes fibers;
providing a hydraulic entangling manifold, the elastomeric film and the nonwoven web traveling in the machine direction to the hydraulic entangling manifold such that the elastomeric film is disposed between the hydraulic entangling manifold and the nonwoven web; and
impinging the elastomeric film with hydro jets from the hydraulic entangling manifold pushing the elastomeric film into the nonwoven web such that at least some of the fibers become embedded in the film.
2. The method of claim 1 , wherein the nonwoven web includes staple fibers, substantially continuous fibers, pulp fibers, or a combination thereof.
3. The method of claim 1 , further comprising positioning the nonwoven web on a forming screen.
4. The method of claim 1 , wherein the film/nonwoven composite is substantially free of film-based microfibers.
5. The method of claim 1 , wherein the hydro jets continuously bond the nonwoven web to the elastomeric film such that the nonwoven web is uniformly bonded to the elastomeric film to provide a homogeneous elastic material.
6. The method of claim 1 , wherein the hydro jets do not rupture the elastomeric film.
7. The method of claim 1 , wherein the hydro jets rupture the elastomeric film to provide apertures such that the film/nonwoven composite is breathable.
8. The method of claim 1 , further comprising drying the film/nonwoven composite.
