A low trauma pressure-sensitive adhesive coated substrate comprising a sheet material, tape or laminate structure designed to adhere to skin or like surfaces. The pressure-sensitive adhesive layer of this adhesive coated substrate is a fibrous adhesive layer generally having a basis weight of from 5 to 200 g/m2 applied to a conformable backing or substrate. The fibrous adhesive layer has a textured outer face and persistent porosity between discrete adhesive fibers. Generally, the fibrous adhesive layer has a MVTR (measured by ASTM E 96-80 at 40.degree. C.) of at least 1000 g/m2/day, preferably at least 6000 g/m2/day.

1. A low trauma adhesive coated substrate comprising a backing substrate formed of an absorbent material having a water absorbency of at least 100% and a fibrous adhesive layer said fibrous adhesive layer comprising an entangled web of discrete pressure-sensitive adhesive fibers, with a basis weight of 5 to 200 g/m2 of which pressure-sensitive adhesive fibers are adhesive along their entire length, of which entangled web of discrete pressure-sensitive adhesive fibers is persistently porous and has a MVTR of at least 1000 g/m2/day, said adhesive coated substrate having an initial adhesion to dry skin of at least 20 g/2.5 cm (0.08 N/cm), an initial wet skin adhesion of at least 20 g/2.5 cm (0.08 N/cm), and provides a TEWL after 10 tape pulls per day for two consecutive days of less than 20 grams/m2/hour at 0.5 hours after the last pull, with an original TEWL of from about 3 to 7 grams/m2/hour.
