After thermal processing, the prescribed re-cooling of the web is especially important. If the web temperature is excessively high relative to the subsequent stage of processing, such as cold pad batch dyeing or chemical web impregnation, the temperature of the dye or chemi- cal bath will quickly rise and a significant amount of product quality will be lost. At Dhaval, we primarily produce two types of cooling cylinders: those with guide spiral double shell cooling cylinders or those with a waterspraying system without controlled water circulation. Through the careful application of the water guiding system, an even cooling and a temperature toler- ance of less than 8°C to 10°C across the entire width are ensured.
