Abstract

An elastomer material for a wristband or components for horology configured to be in contact with skin, the elastomer material including a moisture wicking mechanism. The wicking mechanism includes hydrophilic microfibers capable of wicking away and neutralizing moisture through the material.

First claim

The invention claimed is:

1. An elastomer material for wristbands or components for horology intended to be in contact with skin, the elastomer material comprising:
moisture wicking means, wherein the wicking means includes hydrophilic microfibers made of a synthetic material from the polyamide or polyester family, the microfibers forming channels in the elastomer material to transport moisture by capillary action through the material; and
thermally conductive fillers selected from zinc oxide and boron nitride.

2. The elastomer material according to claim 1 , including an antimicrobial additive of organic zinc compound or silver salts or aluminium salts type.

3. The elastomer material according to claim 1 , wherein the material is chosen from thermoplastic elastomers, polyurethane, polyether block amine, copolyester elastomers, acrylic elastomers, or styrene elastomers.

4. The elastomer material according to claim 1 , wherein the material is chosen from hot vulcanizable elastomers, fluoroelastomers, acrylonitrile butadiene copolymers, silicones, or ethylene propylene diene monomer.

5. The elastomer material according to claim 1 , wherein the material is chosen from cold vulcanizable elastomers or silicones.

6. The elastomer material according to claim 1 , wherein the hydrophilic microfibers have a fineness of less than 150 mTex.

7. The elastomer material according to claim 1 , wherein the hydrophilic microfibers are made of a cellulosic material, cotton, linen, or from synthetic derivatives or viscose.

8. The elastomer material according to claim 1 , wherein the hydrophilic microfibers have a cross-section with n channels, wherein n >2.

9. The elastomer material according to claim 8 , wherein the cross-section of the hydrophilic microfibers has an oblong shape with grooves or a helical shape.

10. A method for manufacturing a wristband, comprising at least one portion made from an elastomer material, the elastomer material including at least hydrophilic microfibers, thermally conductive fillers, and an antimicrobial additive, wherein the method comprises:
forming a mixture from the elastomer material;
adding to the mixture obtained in the forming at least hydrophilic microfibers, thermally conductive fillers and an antimicrobial additive;
forming the wristband from the mixture obtained in the adding by a molding process,
wherein the hydrophilic microfibers are made of a synthetic material from the polyamide or polyester family, and the hydrophilic microfibers form channels in the elastomer material to transport moisture by capillary action through the material.

11. The method according to claim 10 , wherein the elastomer material is chosen from thermoplastic elastomers and vulcanizable elastomers.

12. A method for assembling a wristband obtained by the method according to claim 10 , wherein the method comprises:
forming a first layer of a wristband intended to be in contact with the skin;
assembling an aesthetic layer on top of the first layer.

13. An assembly method according to claim 12 , wherein the aesthetic layer is leather, fabric, polymer, or any other decorative element.

14. An elastomer material for wristbands or components for horology intended to be in contact with skin, the elastomer material comprising:
moisture wicking means, wherein the wicking means includes hydrophilic microfibers made of a synthetic material from the polyamide or polyester family, the microfibers forming channels in the elastomer material to transport moisture by capillary action through the material; and
an antimicrobial additive of organic zinc compound or silver salts or aluminium salts type.
