ABSTRACT:
Method of making a transparent film by forming two or more melt streams, combining the melt streams into a multilayer melt stream, extruding the layered melt stream and attenuating with an airstream to form multilayer microfibers, collecting the microfibers as a nonwoven web, and consolidating the web under heat and pressure. At least one of the melt streams is a thermoplastic elastomer and at least one of the melt streams is a thermoplastic material. The transparent web has a generally continuous elastomeric phase with an included array of thermoplastic microfibers.
