ABSTRACT:
A method of manufacturing a cohesive bandage comprising the steps of providing at least one layer of woven fabric and applying a coating containing polybutylacrylate ester and alkylphenyl polyethylene glycol to at least one fabric face is disclosed. In one embodiment, the coating is applied by an airless method, microselectively in statistical distribution where the quantity of coating is controlled by pump pressure. Alternatively, an aqueous dispersion of polybutyl acrylate ester and carboxymethyl cellulose is microselectively and cohesively coated on both sides of the fabric by screen printing to produce a regular dot pattern on both faces of the fabric.
