Abstract

A glove comprising a front sheet (9) and a back sheet (10). At least one of the sheets consists of an outer layer (12) and an inner layer (13) made of polymeric films. The layers are bound to each other. The faces (18) facing each other of at least two adjacent layers (12, 13) are independent from each other so as to allow relative movement (M) between the two layers (12, 13).

Claims

1. Glove comprising a front sheet (9) and a back sheet (10), at least one of said sheets having an outer layer (12) and an inner layer (13) made of polymeric films, said layers being permanently bound to each other along their periphery, characterized in that contacting faces (18) of said inner and outer layers (12, 13) are independent from each other so as to allow relative movements (M) between said inner and outer layers (12, 13) and that the dynamic and static friction coefficient of the contacting faces (18) is less than 0.80.

2. Glove according to claim 1, in which said friction coefficient is lower than 0.70.

3. Glove according to claim 1 characterized in that the adjacent layers (12, 13) contain at least one agent allowing said layers to slide on each other wherein said agent is selected in the group consisting of saturated hydrocarbons, fatty acids, metal soaps, fatty acid monoesters, fatty acids partially esterified polyfunctional alcohols, fatty acid bisamides, stearamide and erucamide.

4. Glove according to claim 1, characterized in that the adjacent layers (12, 13) contain at least one agent allowing each layer to slide on each other wherein said additive consists of particles of bismuth, bismuth oxides, bismuth hydroxides or salts of bismuth.

5. Glove according to claim 4, characterized in that said additive is the bismuth oxide of the formula Bi₂ O₃.

6. Glove according to claim 4, characterized in that said particles have a size lower than 40 microns.

7. Glove according to claim 6, characterized in that said particles have a size lower than 5 microns.

8. Glove according to anyone of the claim 4, characterized in that the layer contains 30 to 80% by weight of said particles.

9. Glove comprising a front sheet (9) and a back sheet (10), at least one of said sheets having an outer layer (12) and an inner layer (13) made of polymeric films, said layers being bound to one another along their periphery, characterized in that contacting faces (18) of said inner and outer layers (12, 13) are independent from each other so as to allow relative movements (M) between said inner and outer layers (12, 13), the adjacent layers (12, 13) contain at least one agent (19) allowing said layers (12, 13) to slide on each other.
