Abstract
The present invention further relates a sublimation printing process of a multilayer system comprising a polyester top layer and at least one heat sensitive polymer layer whereby a temperature gradient is applied during sublimation printing such that the heat sensitive polymer layer is maintained at a temperature below its melting temperature and the polyester top layer is maintained at a temperature above its glass transition temperature to allow diffusion of a sublimation dye into the polyester top layer. The temperature gradient is maintained by using a heat sink element beneath the heat sensitive polymer layer. The temperature gradient can also be maintained by cooling the heat sink element. The cooling preferably occurs with a circulating coolant. The heat sink element comprises a polymer, a ceramic or a metal. The invention further relates to a sublimation printed multilayer system comprising a polyester top layer and at least one heat sensitive polymer layer. The present invention also relates to the multilayer system in the manufacturing of textile, tents, outdoor gear, apparel, clothing, bags, jackets, gloves.
