Abstract
A coating composition for fabrics includes wetted microspheres containing a phase change material dispersed throughout a polymer binder, a surfactant, a dispersant, an antifoam agent and a thickener. Preferred phase change materials include paraffinic hydrocarbons. The microspheres may be microencapsulated. To prepare the coating composition, microspheres containing phase change material are wetted and dispersed in a dispersion in a water solution containing a surfactant, a dispersant, an antifoam agent and a polymer mixture. The coating is then applied to a fabric.
Claims13
A wet coating composition, for coating fabrics to produce coated fabrics specially adapted for thermal regulation across the coated fabrics, comprising:
- 100 parts dry weight of a polymer binder;
- 70 to 500 parts by dry weight of thermo-set microspheres containing a phase change material having a capacity for repeated thermal regulation for each 100 parts dry weight of said polymer binder;
- 0.001% to 6% dry weight of a surfactant based on the dry weight of said microspheres;
- 0.001% to 6% dry weight of a dispersant based on the dry weight of said microspheres;
- 25% to 80% by weight water based on the total weight of the wet coating composition;
- and
- 0% to 1% by weight of dry antifoam agent based on the total weight of the wet coating composition.
