Shock pre-drying is a combination of vacuum extraction and convective drying methods that provides rapid drying due to the synergy between heat energy and mechanical forces. Shock pre-drying of polyester (PE) fabrics and their blends was performed. Experimental results showed that complete drying of PE fabrics was possible. As well as pre-drying, use of the method for intermediate drying after thermosol dyeing was also studied. The method prevents center-surface and horizontal migration. It also ensures higher color yield values at the face side of the fabrics after the thermosol process, compared to squeezing, and therefore leads to chemical savings.
