DIPPING COMPOSITE MATERIAL FOR ENHANCING CUT RESISTANCE OF CHEMICAL-RESISTANT GLOVES

Abstract

Disclosed is a dipping composite material for enhancing the cut resistance of chemical-resistant gloves, wherein an additive is added to a latex, and the additive is a metal oxide and/or silica and/or glass fiber and/or basalt fiber and/or aramid fiber. The present invention improves the formula of a dipping layer such that the dipping layer has the cut resistance, which can significantly improve the cut resistant level of gloves.
