| Abstract: | The blend fiber was prepared from PP and normal-pressure cation-dyeable copolyester and was dyed until saturation in different concentration of cationic blue X-GRRL at l00℃ and 117℃. The thermodynamic parameters of the blend fiber were studied. The standard dyeing affinity of this fiber in this dyebath at 1001 was calculated as -7.94 kJ/mol,the dyeing heat from l00℃ to 117℃ was 4.21 kJ/mol, and the dyeing entropy at 100℃ was -10.0J/(mol·K). |
