Abstract
A modified elastomeric glove is disclosed having a lubricous coating made up of polyvinyl alcohol and a thickening agent. The thickening agent is initially added in order to increase the processability of the polyvinyl alcohol coating in order to prevent runbacks and drips during the manufacturing process. A hydroscopic thickener may be used. The polyvinyl alcohol coating becomes lubricous when wetted in a water bath and therefore becomes particularly useful in applying a water-activated resin casting material for forming orthopaedic casting bandages.
Claims11
A method of making a lubricous glove comprising the steps of:
- a) providing a form having a shape to simulate a hand;
- b) coating said form with a layer of elastomeric material to form a hand shaped casing;
- c) dipping said casing in a solution including polyvinyl alcohol and a thickening agent at ambient temperatures to form a coated casing;
- and
- d) removing said coated casing from said solution and drying.
A method of making a lubricous glove for use in application of resinous material comprising:
- a) providing a glove form;
- b) dipping said glove form into a coagulator bath to coat said glove form with a substance for coagulating latex;
- c) thereafter dipping said glove form into a latex solution and maintaining said glove form in contact with said latex for sufficient time to have said substance form a latex gel layer of said form for curing;
- d) dipping said form having latex thereon into a solution including polyvinyl alcohol and a thickener at substantially ambient temperatures depositing thereon a layer of said polyvinyl alcohol and thickener;
- e) exposing said glove form to elevated temperatures to dry said layer of polyvinyl alcohol and thickener;
- and
- f) removing said polyvinyl alcohol and thickener coated latex from said form.
