Claims20
A thin, abrasion resistant supported glove, comprising:
- a knitted liner comprising at least one yarn;
- and
- a polymeric layer disposed on at least a portion of the knitted liner, the polymeric layer comprising a polymeric composition including a mixture of a nitrile-butadiene material and a water-based polyurethane material, wherein the polymeric composition has a total solids content of less than or equal to 35% and penetrates the at least one yarn approximately 50% or less of a thickness of the yarn, resulting in a thin, abrasion resistant glove.
A method for making a thin, abrasion resistant supported glove, comprising:
- dressing a knitted liner comprising at least one yarn onto a former
- disposing a coagulant solution comprising acetic acid onto the knitted liner and former;
- drip-drying the knitted liner;
- dipping the knitted liner and former into a polymeric composition, the polymeric composition comprising a total solids content of equal to or less than 35%, thereby disposing a polymeric coating onto the liner;
- and
- curing the polymeric coating, wherein the polymeric composition penetrates 50% or less of a thickness of the at least one yarn of the knitted liner and the polymeric coating is approximately 0.01 to 0.02 mm in thickness.
