Open the CIPO recordAbstract From the Canadian patent
Apparatus is provided for effective low liquor wet processing of textile piece goods with exceptional flexibility as to type of fabric that may be handled and processing conditions that may be applied. The wet processing is effected by applying the treated liquor to the fabric in a non-persistently foamed condition so that the liquid tends to decay to liquid phase in the course of fabric treatment and is available for recovery so as to be recycled for continued treatment of the fabric.
