Abstract
A surgical glove has inner and outer surfaces. At least one of the surfaces is treated with a treatment consisting of a non-ionic hydrocarbon solution with a carbon chain in the range of 8-16 and containing a hydrophilic functionality with a pH within the range 4.5-6.5. After treatment, the treated surface or surfaces are dried, the glove packaged and then irradiated. The treatment controls the initial contact angle of the surface to be less than 70 degrees, so that liquid material will spread quickly across the treated surface or surfaces, thereby ensuring that the presence of the liquid, indicative of the glove having been compromised, is visible to the wearer or other observer as quickly as possible.
