Abstract:
A low trauma adhesive coated substrate comprising a backing substrate and a porous fibrous adhesive layer, having a basis weight of from 5 to 200 g/m.sup.2, adhesively attached to said backing substrate, said fibrous adhesive layer comprising an entangled web of discrete pressure-sensitive adhesive fibers, which pressure-sensitive adhesive fibers are adhesive along their entire length, and which pressure-sensitive adhesive fibers form an outer adhesive surface on the fibrous adhesive layer for adhesion to skin and an inner adhesive surface on the fibrous adhesive layer for adhesion to the backing substrate, which entangled web of discrete pressure-sensitive adhesive fibers has a MVTR of at least 1000 g/m.sup.2 /day, provides an initial adhesion to skin of at least 20 g/2.5 cm, and provides a TEWL after 10 tape pulls per day for two consecutive days of less than 20 grams/m.sup.2 /hour at 0.5 hours after the last pull (with an original TEWL of from about 3 to 7 grams/m.sup.2 /hour).
