ABSTRACT:
A thermoplastic fabric for use as a support fabric in interfacing, underlining, and applique carries a persistent electrostatic charge that causes the fabrics in contact therewith to cling thereto in a nonslip relationship. This facilitates sewing of the layers together. The preferred support fabric is a nonwoven fabric such as meltblown and spunbonded fabrics.
