ABSTRACT OF THE DISCLOSURE A method of producing breathable, conformable, elastic, pressure-sensitive, permanently tacky, adhesive bandaging material from a fabric which has been formed by interweaving essentially non-stretch filling yarns with stretch and non-stretch warp yarns, said method comprising conveying a continuous web of said fabric in a substantially relaxed condition, applying steam to the relaxed fabric, and applying an adhesive layer to the back side of the relaxed fabric. A breathable, conformable, elastic, pressure-sensitive, permanently tacky, adhesive bandaging material comprising a fabric formed by essentially non-stretch filling yarns inter- woven with stretch and non-stretch warp yarns, the fabric normally being in a relaxed condition, an adhesive applied in a level layer to the entire back side of the relaxed fabric such that, in its relaxed state, the bandaging material has an adhesive layer which has a smooth exposed surface and a sub- stantially uniform depth throughout, and such that, in its stretched state, the adhesive bandaging material has an adhesive layer which has a non-uniform, discontinuous surface and a depth which varies from being relatively great where the non-stretch warp yarns extend to the back side of the fabric to being relatively slight or even zero where the non-stretch warp yarns extend away from the back side of the fabric.
