How can I get a print on CoolMax that won make the wearer feel hot and sweaty?
CoolMax is a very light weight fabric often used in cycling and running wear. CoolMax fibers are designed to wick perspiration away from the body and provide a cooling effect through the rapid evaporation of moisture. Any plastisol print would at least partially block this evaporation process and is therefore not the best choice. For white or light-colored garments (CoolMax is generally white) Union Ink’s Unisoft Sub-Dye Sublimation Transfer Dyes will do the job. Use them to print sublimation transfers that you then apply to the CoolMax garment. Because the melting point of CoolMax is 493 F (256 C) the heat required for applying sublimation transfers should not damage the fabric. For direct printing, Union Ink’s Aerotex (ATEX) or Unidye (UNDY) water-base inks are recommended.
