Preliminary discussion on identification method of elastomultiester
A more complete test process was used to identify theelastomultiester,first confirm its composition,then separate the two components,and then identify and confirm the composition of each component,and finally obtain the qualitative conclusion of the composite fiber.7 quantitative dissolution methods were tried to dissolve one component of elastomultiester,and the effect of separating two components was achieved.The results showed that the dissolution degree of one component of the sample was better than that of the other component by 3 methods,and the purpose of separation was basically achieved.The research direction of the separation of elastomultiester components by dissolution method and the identification standard of bicomponent fiber were put forward.
