Breathable backing for an adhesive article

摘要

There is provided pressure-sensitive adhesive coated breathable nonwoven tape backing substrate where the nonwoven tape backing comprises a fibrous nonwoven web formed in part by multicomponent fibers having an adhesive component region. The multicomponent fibers are distributed throughout the width dimension of the nonwoven tape backing such that adhesive component region is exposed on both outer faces of the nonwoven tape backing. The adhesive component region is preferably a pressure-sensitive adhesive region formed by hot melt coextrusion of at least two components to form the multicomponent fibers. A pressure-sensitive adhesive tape layer is coated onto at least one face of the nonwoven tape backing which pressure-sensitive adhesive tape layer is preferably of the same type of adhesive as that forming the adhesive region of the multicomponent fiber or is at least compatible with the adhesive region of the multicomponent fiber such that the adhesive has enhanced adhesive properties to the pressure-sensitive adhesive tape layer.
