Study On Polyester Dyeing And Dispersing Leveling Agents

Polyester is the world's largest varieties of synthetic fiber,polyester processing of the most important process for dyeing,and other fibers have a relatively large difference,polyester does not contain the normal dye on the need for reactive groups,is through the polyester fiber swelling,Disperse dyes into the polyester fiber and dyeing,processing,easy to produce color flowers,color points,dyeing a low success rate of the problem,more waste of water resources and energy.High temperature and high pressure dyeing process is widely used in dying polyester fabrics,high temperature dyeing process is in high temperature and high pressure conditions,the disperse dyes evenly in the polyester fiber on the process,in which the dispersing agent in polyester dyeing has a very important role.In this test,the effect of dispersing leveling agent on the dyeing of polyester was taken as the main research object.The laboratory synthesized nonionic surfactant castor oil polyoxyethylene ether and anionic surfactant triphenyl vinyl phenol polyoxyethylene ether sulfate Divided,And compounded into a dispersing leveling agent.Mainly to identify the different dispersing leveling agent,the impact on the dyeing,and provide evaluation method of the dispersing leveling agent to the factory.The results show that the dispersing leveling agent A has very balance performance,more suitable for polyester dyeing,The dispersing leveling agent A and B are mixed type,but the dispersing leveling agent is not good as the dispersing leveling agent A.Suitable for the ratio achieve better performance,such as the mix of poor mix may get the opposite effect.
