Abstract
Method of dyeing a textile web having a relatively large volume or relief-like construction which includes immersing the web in a dye solution having a dye concentration corresponding to the quantity of liquid to be squeezed from the web in a subsequent dewatering step, passing the web between two absorbent endless entrainer members of a squeeze foulard that are continuously saturated with the dye solution prior to engagement of the endless entrainer members with the web, and squeezing the web in the foulard so as to dewater it to less than substantially 40% moisture with respect to dry weight of the web, then passing the web through an infra-red channel at an adjusted relatively low drying velocity so as to prevent the formation of cloudiness in the dye distribution and drying the web to a final moisture content of at most 5% with respect to dry weight of the web, and subsequently completing the steps of the dyeing process per se.
