Abstract (en)
[origin: WO9623643A1] The present invention relates to a multiple-dip process for producing a powder-free glove having a polyurethane coating. The method of this invention involves dipping a former into a powder-free aqueous dispersion or emulsion of a polyurethane polymer or copolymer to form a first layer; dipping the first layer while still on the former into a powder-free coagulant; dipping the first layer into a latex compound to produce a second layer; leaching the second layer in water; curing the first and second layers; and stripping the resulting glove from the former. Gloves produced according to this process can be made in a continuous fashion without interruption and are more economical than conventional processes used to make powder free gloves. The method of this invention does not include a halogenation step but rather employs environmentally friendly materials which do not pose toxicity of environmental issues.
