Abstract

Continuous textile dyeing and finishing processes are strongly influenced by the temperature differences between liquor and fabric during the padding operation. The temperature of the padding solution is usually higher than that of the fabric, the difference being as much as 60°C. The temperature of the fabric does not reach the temperature of the solution throughout the entire padding process. Important changes in wetting, penetration, and reactivity occur as a consequence of preheating of the fabric. Chemical and physical changes in cellulosic fibers can be shown to occur after short thermal treatments. New methods for the dyeing and finishing of cotton fabrics have been made possible by the Thermotex Process.
