Abstract:
A method of producing an apertured film with attached fibrils having a cloth-like look and feel, comprising the steps of:dispensing a controlled layer of fibrils adjacent to an extrusion die having a plurality of air slots, releasing air streams at converging angles from said air slots to create a turbulent zone for the dispersion of a polymer melt having a first melting point; forming melt blown fibers by releasing said polymer melt having a first melting point from said extrusion die in said turbulent zone in fiber-like strands; combining said polymer melt having a first melting point with said layer of fibrils to create a composite temporary web; combining said composite temporary web with a polymer melt having a second melting point to create the permanent film with attached fibrils, wherein said polymer melt having a first melting point in said composite temporary web melts and is absorbed into said polymer melt having a second melting point to form a permanent film with attached fibrils; and drawing the permanent film with attached fibrils between a forming screen having perforations and a vacuum therein and a nip roll to form apertures in the permanent film.
