Abstract
This invention relates to a method for hiding stains in medical dressings and other textile substrates. The method includes applying a metallic silver coating to a textile substrate via a plasma enhanced chemical vapor deposition (PECVP) process. The metallic silver coating effectively hides any stain that comes into direct contact with the treated substrate by transferring the liquid beneath the surface of the coating. The invention also relates to textile substrates containing metallic silver coatings.
Claims18
A stain hiding fabric comprised of a textile substrate having a wound contact surface and a non-wound contact surface, wherein the wound contact surface contains a metallized silver coating having a thickness in the range from 1% to 60%, based on the total thickness of the textile substrate.
A method for making a stain hiding fabric comprising the following steps:
- (a) Providing a textile substrate having a wound contact and a non-wound contact surface,
- (b) Exposing the wound contact surface of the textile substrate to a plasma enhanced chemical vapor deposition (“PECVD”) process, and
- (c) Allowing the PECVD process to add a metallic silver coating to the wound contact surface of the textile substrate.
A method for hiding stains in a textile substrate comprising the following steps:
- (a) Providing a textile substrate having a wound contact and a non-wound contact surface,
- (b) Exposing the wound contact surface of the textile substrate to a plasma enhanced chemical vapor deposition (“PECVD”) process,
- (c) Allowing the PECVD process to add a metallic silver coating to the wound contact surface of the textile substrate to form a coated textile substrate, wherein the metallic silver coating has an exterior surface facing outward from the textile substrate and an interior surface facing inward to the textile substrate,
- (d) Exposing the exterior surface of the metallic silver coating to an aqueous liquid, and
- (e) Allowing the aqueous liquid to move from the exterior surface of the metallic silver coating to the interior surface of the metallic silver coating.
