Abstract
Abstract A stretchable strap material for the shoulder straps of brassieres, slips, nightgowns, swimsuits or other articles of feminine wearing apparel is constituted by a raschel-knitted fabric tape having the desired hand and appearance to match or complement the fabric of the associated wearing apparel and in which longitudinally extending filaments or strands of spandex are laid in, and such raschel-knitted fabric tape is longitudinally folded so that portions thereof define the opposite faces of an outer shell or envelope containing a nonwoven, open randomly reticulate web of thermoplastic synthetic elastic fibers by which confronting portions of the folded tape are bonded together.
