Abstract
The present invention is directed towards a tanned leather product that is impregnated with a plurality of microspheres containing a temperature stabilizing material. The present invention is also directed to a tanning process for embedding the microspheres into the leather. The thermal stabilizing material is a phase change material that allows the leather to have enhanced thermal properties when exposed to heat or cold.
Claims16
A tanned leather comprising:
- an internal fiber matrix;
- a plurality of microspheres containing a temperature stabilizing material, said microspheres being disposed and embedded within the fiber matrix in a sufficient amount so that the microspheres enhance the thermal stability of the leather when subject to heat or cold.
A method of impregnating a material selected from skins and hides, wherein the method comprises the steps of:
- placing the material in a container;
- adding a tanning agent to the container;
- combining a plurality of microspheres containing a temperature stabilizing material with a liquid to form a suspension;
- adding the suspension to the container;
- and
- agitating the contents of the container until a portion of the micorspheres are disposed and embedded within the fiber matrix so that the microspheres enhance the thermal stability of the material when subjected to head or cold.
