Process of making a multiple domain fiber having an inter-domain boundary compatibilizing layer |
摘要 |
Multicomponent fibers and methods and apparatus for producing the same are provided such that an inter-domain boundary layer is interposed between distinct domains formed of incompatible polymers so as to minimize (if not eliminate entirely) separation of the domains at their interfacial boundary. The inter-domain boundary layer is formed of a heterogeneous mixture of the polymers forming the respective adjacent domains between which the boundary layer is interposed. The inter-boundary layer will most preferably include rivulets or fingers of each polymer forming the adjacent domains which interlock with one another in a randomly tortuous manner. These different polymer rivulets thereby effectively increase the surface area and mechanical interlocking at the interfacial boundary between the fiber domains thereby increasing the adhesion therebetween.
