Abstract
A composite includes a first substrate, a second substrate, a third substrate and a discontinuous adhesive structure disposed intermediate the first and second and the second and third substrates for securing the first, second and third substrates together to form a composite without significantly modifying the properties of any of the substrates. The discontinuous adhesive structure is an array of substantially linear filaments or strands of an adhesive. The composite combines high moisture vapor transmission, high resistance to penetration by liquids and high resistance to viral penetration even at a pressure of at least 3 psi, thereby rendering it suitable for medical applications such as surgical gowns, etc.
