Abstract: A process of making a non-lofted fiber veil (14) for the production of insulation (e.g., thermal, for blown-in applications), having X, Y and Z vector directions of the fibers includes melt blowing a polymer to form molten fibers having molecules oriented along the length (or X vector direction) of the fibers, placing the fibers on a roller (12) spinning at a rate to provide additional orientation of the molecules of the fibers into the Y vector direction, and cooling the fibers while on the roller (12) to form the non-lofted fiber veil (14).
