Abstract
The invention provides a functional leather product, preferably for a glove or a shell of a glove having a capacitive, near field communication enabling perceptible and/or protective function, and a method for producing said leather product. The leather product comprises leather in form of a cut piece comprising at least in part a sandwich structure of at least two layers, wherein said sandwich structure comprises a first layer, which comprises an upper split leather obtained by at least partially splitting said cut piece of leather parallel to its upper surface at a predetermined cross-sectional depth of maximum about 4.95 mm, preferably 2.5 mm and a second layer comprising a functional layer, wherein the functional layer is attached at least in part to the first layer.
Claims19
A functional leather product for a glove having a capacitive,
- near field communication enabling, perceptible and/or protective function, the leather product comprising:
- leather in form of a cut piece comprising at least in part a sandwich structure of at least two layers;
- wherein said sandwich structure comprises:
- a first layer, which comprises an upper split leather obtained by at least partially splitting said cut piece of leather parallel to its upper surface at a predetermined cross-sectional depth of maximum 4.95 mm;
- and
- a second layer comprising a functional layer,
- wherein the functional layer is attached at least in part to the first layer;
- wherein the overall thickness of the first layer is in the range of from about 0.05 mm to 0.45 mm;
- wherein the functional layer is a conductive silicon sheet or a conductive rubber sheet and the functional layer has an area of at least approximately 50 cm2;
- and
- wherein the conductive silicon sheet or conductive rubber sheet has a surface resistivity of less than 1000 Ohm per square and/or a volume resistivity of less than 5 Ohm-cm.
A functional leather product for a glove having a capacitive, near field communication enabling, perceptible and/or protective function, the leather product comprising:
- leather in form of a cut piece comprising at least in part a sandwich structure of at least two layers;
- wherein said sandwich structure comprises:
- a first layer, which comprises an upper split leather obtained by at least partially splitting said cut piece of leather parallel to its upper surface at a predetermined cross-sectional depth of maximum 4.95 mm;
- and
- a second layer comprising a functional layer,
- wherein the overall thickness of the first layer is a maximum of 0.50 mm;
- wherein the functional layer is attached at least in part to the first layer;
- wherein the functional layer is a conductive silicon sheet or a conductive rubber sheet;
