Abstract
There is described a woven bandage which exhibits a crepe effect and which contains composite warp yarns (1) and weft filaments (7) wherein the composite warp yarns (1) are formed by twisting a staple fiber yarn (2) and a textured filament yarn (3) together. The staple fiber yarn (2) forms loops (4) which gives the bandage a crepe effect. There is also described a process for the manufacture of such woven bandages and an article of manufacture which includes the composite warp yarns used in the woven bandage.
