Thermoplastic casting material and method for production thereof

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.

Cohesive bandage

The textile fabric is used as a wound dressing in much the same way as dressing gauze with improved characteristics compared with the latter and comprises a central web portion of man-made fibers having a high surface tension, and on either side thereof web portions formed from absorbent, cellulosic yarns. The central web portion is connected by looping to the outer web portions so that after folding, a nonstick wound dressing is obtained in which the hydrophobic man-made fibers functioning as the wound covering, come to rest on the wound, while the folded layers of cellulosic fibers behind it, act as an absorbent layer.

Knitted hydrophobic web wound dressing

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.

Method of manufacturing a cohesive bandage

Textile sheet-like structure impregnated or coated with water-hardening synthetic resin, said textile comprising organic fibers with an elasticity modulus of 200 to 2500 daN/mm.sup.2 and having an extensibility in the longitudinal direction of at least 10% before hardening of said resin is useful in preparing orthopaedic support dressings, containers, filters, pipes, reinforcing material, stiffening material, filler or sealer material for hollow spaces or joints, insulating material, in preparing decorative and artistic articles.
