ABSTRACT:
A damage tolerant cut resistant chemical handling glove that is flexible and lightweight comprises a cured, liquid-impervious polymeric latex shell, a knitted cut resistant liner comprising a cotton yarn and at least one cut resistant yarn, the liner being infiltrated with a soft nitrile or polyurethane layer such that the liner bonds to the shell. The soft nitrile or polyurethane layer seals interstices of the cut resistant liner and replicates its rough texture on the external surface of the glove, providing enhanced grip properties. A thin nitrile latex layer applied to and cured together with the polyurethane layer to protect the polyurethane layer from oil or chemical degradation. The intimate seal thus created between the shell and the liner prevents accumulation of liquid there between, which prevents formation of a liquid boundary layer and interference with grip properties of the glove.
