摘要：

In order to explore the dyeing mechanism of reactive dye on cotton yarn in SiO2 emulsion (Pickering emulsion)system, Reactive Red M-3BF was used to explore the kinetics for cotton dyeing. The dyeing performance of the dye in Pickering emulsion system and the traditional aqueous system were compared, before the data of cotton yarn dyed in Pickering emulsion system was fitted, and the kinetic parameters were calculated and compared with the traditional aqueous system. The results show that the dye utilization of Reactive Red M-3BF in the Pickering emulsion system are higher than that in the traditional aqueous bath dyeing system and the washing fastness is equivalent under the same dye dosages, and the dyeing of reactive Red M-3BF on cotton fibers in both systems conforms to the quasi-second-order kinetic adsorption model equation. The equilibrium adsorption capacity of dye in Pickering emulsion system is higher than that of traditional aqueous system, and the adsorption activation energy is smaller, the half-dyeing time is shortened. Sodium sulfate can increase the equilibrium adsorption capacity and speed up the dyeing rate. Copyright No content may be reproduced or abridged without authorization.
