Abstract

In producing an elastic glove made of rubber or resin and having an interior surface flocked with piles through a step for depositing the piles on a film of a latex composition formed on a surface of a mold conformal to a three-dimensional shape of the elastic glove, a water repellent/hydrophilic pile mixture containing water repellent piles in a proportion of 10 to 80 mass % is used as the piles to uniformize a pile embedded state in a rubber or resin film defining the interior surface over the substantially entire surface of the elastic glove.

First claim

The invention claimed is:

1. A method of producing an elastic glove entirely made of rubber or resin and having an interior surface flocked with a multiplicity of piles, the method comprising the steps of:
dipping a mold conformal to a three-dimensional shape of the elastic glove into an aqueous liquid latex composition containing the rubber or the resin, and taking out the mold to form a film of the latex composition defining at least the interior surface of the elastic glove on a surface of the mold; and
depositing the piles on the film and then vulcanizing the rubber contained in the latex composition or curing or solidifying the resin contained in the latex composition;
wherein hydrophilic piles and water repellent piles are used in combination as the piles, and the water repellent piles are present in a proportion of not less than 10 mass % and not greater than 80 mass % based on a total amount of the hydrophilic piles and the water repellent piles,
wherein the water repellent piles are obtained by treating the hydrophilic piles with stearic acid, calcium stearate, wax or a silicone resin.

2. The elastic glove production method according to claim 1 , wherein the proportion of the water repellent piles based on the total amount of the hydrophilic piles and the water repellent piles is not less than 20 mass % and not greater than 50 mass %.

3. The elastic glove production method according to claim 1 , further comprising the step of: dipping the mold in a liquid latex composition containing rubber or resin, and then taking out the mold to form a film of the latex composition defining an exterior surface of the elastic glove on the surface of the mold before the formation of the film defining the interior surface of the elastic glove.
