ABSTRACT:
Process for manufacturing a fabric having distinctive and sharp differentially colored patterns or designs, which process comprises the steps of: (a) producing a first and a second polyamide, said polyamides having different concentrations of amine groups; (b) producing a first and a second polyamides having different concentrations of carboxyl end-groups and sulfonate groups; (c) producing a first yarn from said first polyamide and a second yarn from said second polyamide; (d) making a fabric having first surface areas defined by said first yarn and second surface areas defined by said second yarn; and (e) chemically dyeing said fabric in a dyeing bath comprising at least one anionic (acid) dyestuff and at least one cationic (basic) dyestuff, whereby said first yarn and therefore said first surface areas are dyed predominantly by said anionic dyestuff and said second yarn and therefore said second surface areas are dyed predominantly by said cationic dyestuff.
