Abstract
A coating is adapted to be applied to a fabric in order to enhance the thermal characteristics thereof. The coating includes integral and leak-resistant microcapsules filled with phase change material or plastic crystals that have specific thermal properties at predetermined temperatures.
Claims16
An article having enhanced thermal storage properties and repeatability of thermal response consisting essentially of:
- a base material selected from the group consisting of fabrics and fibers, and
- a coating covering at least a portion of the surface of said base material and comprising:
- a polymeric binder, and
- a plurality of microcapsules dispersed throughout and submerged within said binder on the surface of said base material so as to be surrounded thereby, said microcapsules containing a temperature stabilizing means selected from the group consisting of phase change materials and plastic crystals, whereby the article exhibits enhanced thermal stability when subjected to heat or cold.
1 more element
A fabric consisting essentially of, in combination:
- (a) a base fabric substrate and
- (b) a flexible polymer directly coating and covering at least a portion of said substrate, a plurality of microcapsules dispersed throughout said coating so as to be covered and surrounded thereby, said microcapsules containing a temperature stabilizing means selected from the group consisting of phase change materials and plastic crystals and being positioned on the surface of said substrate, whereby the coated substrate exhibits enhanced thermal stability when subjected to heat or cold.
