ABSTRACT:
Processes for dyeing, print-dyeing and differentially dyeing smooth-dry cellulose containing fabric are disclosed. Cellulose containing fabric is treated with a solution of crosslinking agent and a reactive additive which can be either polyethylene glycol or choline quaternary. The resultant fabric can then be dyed with a cellulosic dye. Print-dyeing is accomplished by selective application of a choline quaternary to a fabric padded crosslinking agent or by printing with a combination of crosslinking agent and choline quaternary on an untreated cellulosic fabric. These treatments are then followed by curing and dyeing. Differential dyeing is accomplished by first treating separate yarns with different solutions containing crosslinking agent with and without choline quaternary, drying, knitting, curing and dyeing the knitted fabric.
