Abstract

A sheet-form composite (10) suitable as a spyrosorbent wound dressing and exhibiting differential moisture vapor transport rate properties, is disclosed. The sheet-form composite includes a hydrophilic, differential ratio of wet to dry moisture transport rate greater than 1 and a dry moisture transport rate greater than about 2,600 g/m2/24 hrs.
This film layer (12) is laminated to a hydrophilic exudate transport layer (14). The exudate transport layer can itself be, or can further include, a hydrophilic pressure sensitive adhesive (18) applied in a continuous or discontinuous pattern. The sheet-form composite has a moisture vapor transport rate of greater than 2,000 g/m2/24 hrs when dry, and a wet to dry moisture vapor transport rate ratio in the range of about 1.5 to about 10.
