Abstract
There is provided, in accordance with the principles of the present invention, a glove having a textured surface or textured foam coating produced by embedding a layer of discrete particles, such as a salt, into a previously formed liquid layer, gelling or curing the layer and dissolving the discrete particles to leave a textured or textured foamed surface.
Claims18
A process for making a cured textured glove, the process comprising:
- providing a support layer of a dip-coated, gelled latex or of a non-latex material on a former;
- dip-coating the former with the support layer in a coagulatable aqueous latex emulsion composition to form an ungelled outer layer of emulsion composition;
- applying discrete particles of multi-faceted salt to the ungelled outer layer of emulsion composition;
- coagulating the ungelled outer layer of emulsion composition where the particles of multifaceted salt are in contact with the ungelled outer layer of emulsion composition to form a gelled outer layer so that impressions replicating the multi-faceted shape of the particles of salt are formed in the gelled outer layer;
- dissolving the particles of multi-faceted salt;
- heat curing the gelled outer layer after the step of dissolving to form a cured outer layer;
- and
- stripping the support layer and the cured outer layer from the former to form the cured textured glove comprising the impressions replicating the multi-faceted shape of the particles of salt.

A process for making a cured textured glove, the process comprising:
- treating a former with a coagulant;
- dip-coating the former in a coagulatable aqueous latex emulsion composition to form a gelled support layer of latex;
- washing the gelled support layer of latex to remove residual surface syneresis products;
- drying the gelled support layer to remove excess water on the gelled support layer;
- dip-coating the former with the gelled support layer in a coagulatable aqueous latex emulsion composition to form an ungelled outer layer of emulsion composition;
- applying discrete particles of multi-faceted salt to the ungelled outer layer of emulsion composition;
