A flexible, breathable laminate is provided for use in, for example, hospital gowns and the like, or tents. The article prevents liquids such as blood, alcohol and water from penetrating through internally while at the same time permits water vapor such as perspiration to pass out externally. The article comprises an inner layer of hydrophobic material and an outer attached layer of hydrophilic material containing a solid particulate or a liquid additive. For its intended uses, the article is fabricated possessing the following favorable combination of properties when compared to prior art materials: water vapor permeability, non-glare outer surface, bacteria barrier, comfort and/or drape, non-linting, liquid resistance, sterilizability and antistatic characteristics.

A flexible layered article suitable for use in hospital gowns and the like, or tents, which permits transfer of water vapor preventing build-up of internal moisture comprising: (a) a flexible inner layer of hydrophobic material having a moisture vapor transmission rate exceeding 1000 gms./m2. day and an advancing water contact angle exceeding 90 degrees; and (b) a continuous outer hydrophilic layer attached to the outer face of said inner hydrophobic layer, said hydrophilic layer having a moisture vapor transmission rate exceeding 1000 gms./m2. day, said outer hydrophilic layer containing a particulate solid pigment and a liquid antistatic agent dispersed throughout said hydrophilic layer to impart color and antistatic properties to said layered article but not impair its moisture vapor transmission property.
