Abstract:Cationic native starch (CNS) and cationic hydrolyzed starch (CHS) were investigated in physical modification of cotton to realize salt-free dyeing of reactive dyes and their application properties were compared. Adsorption isotherm studies of C.I. Reactive Red 2 on the modified cotton presented the dyeing followed Langmuir-type model. The dyeing properties of the fibers modified with CNS and CHS were investigated and compared. The results showed the dye fixation and fastness properties of both C.I. Reactive Red 2 and C.I. Reactive Blue 19 on CNS modified cotton were inferior to that on the untreated and CHS modified ones.
