Abstract

A cohesive bandage fabricated according to a method comprising the steps of providing at least one layer of woven fabric and applying a coating containing polybutylacryate ester and alkyphenyl polyethylene glycol ether 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.

Claims

1. A cohesive bandage comprising at least one layer of woven fabric, a coating applied to at least one face of said fabric, said coating made by the method of (1) preparing an adhesive substance formed from an aqueous dispersion of 50% of one thousand parts cross-linked polybutyl acrylate ester, and two parts alkylphenyl polyethylene glycol ether and ten parts stabilizer (2) applying said adhesive to said fabric, and (3) drying said fabric.

2. A cohesive bandage comprising at least one layer of woven fabric, a coating applied to at least one face of said fabric, said coating made by the method of (1) preparing an adhesive substance formed from an aqueous dispersion of 60% of 100 parts non-cross linked polybutyl acrylate ester, and one part carboxymethyl cellulose (2) applying said adhesive substance to said fabric, and (3) drying said fabric.
