Abstract

Processes of applying conductive composites on flexible materials, transfer assemblies, and garments including conductive composites are disclosed. The processes include positioning the conductive composite relative to the flexible material, the conductive composite having a resin matrix and conductive filler, and heating the conductive composite with an iron thereby applying the conductive composite directly onto the flexible material. Additionally or alternatively, the processes include positioning the conductive composite relative to the clothing, and heating the conductive composite thereby applying the conductive composite on the clothing. The garments include the flexible material and the conductive composite positioned directly on the flexible material. The transfer assembly has the conductive composite on a transfer substrate. The transfer substrate is capable of permitting heating of the conductive composite through the transfer substrate, the heating being at a temperature that permits applying the conductive composite to the flexible material.
